Camp Half-Blood Chronicles

Percy Jackson and the Olympians main characters

Percy Jackson

Main article: Percy Jackson

Perseus "Percy" Jackson is a young demigod, the son of the mortal Sally Jackson and the Greek god Poseidon. He is the main protagonist and first-person narrator in the Percy Jackson & the Olympians series and appears directly in every book of the Camp Half-Blood chronicles except The Lost Hero. He is twelve years old in The Lightning Thief. In The Blood of Olympus, Percy and his girlfriend Annabeth Chase plan to finish senior year in New York before heading to the college in New Rome (a sentiment they reiterate in The Hidden Oracle).[1]

The powers he inherited from his father include controlling water, making hurricanes, breathing underwater, and talking to horses and sea creatures. He is also a notably good swordsman. Percy's fatal flaw is excessive personal loyalty, which he does not at first see as a danger.[2] Throughout the series, Percy fights by using a ballpoint pen named Anaklusmos (Ancient Greek for "riptide") that changes into a "celestial bronze" sword when uncapped (in the books) or clicked (in the movies). He is described as having a "Mediterranean" complexion, with black hair and his father's sea green eyes.[3]

In the films, he is portrayed by Logan Lerman.

Annabeth Chase

Annabeth Chase is one of Percy Jackson's closest friends and later his girlfriend, first appearing as a twelve–year-old who helps nurse him back to health after he fights the Minotaur. She is the daughter of the goddess Athena and mortal history professor Frederick Chase, from whom she has an extensive paternal family. Annabeth has blond hair, stormy gray eyes, and tan skin. As a daughter of Athena, she is naturally intelligent, with a particular gift for strategy and architecture. At the end of The Last Olympian, she is even assigned to redesign the damaged Mount Olympus. Her fatal flaw is hubris, which is excessive pride. She is also described by her teacher Chiron as "territorial about her friends", which is manifested in several moments of jealousy and distrust. In The Lightning Thief, it is revealed that she is terrified of spiders.[4]

Annabeth runs away from her father and stepfamily at age seven and encounters Luke Castellan and Thalia Grace. They live as runaways until they are found by Grover Underwood and taken to camp. Annabeth remains attached to Luke and convinced of his goodness even after his decision to support Kronos.[4] Her attempts to bring Luke back into the fold are an important theme in the books. Annabeth is crucial to the plot of each book in the Camp Half-Blood Chronicles, in various ways. She leads quests in The Battle of the Labyrinth and The Mark of Athena.[5] She also spends some time in Tartarus with Percy and Bob the Titan during the House of Hades. At the end of the series, she and Percy plan to finish high school in New York and then attend college in New Rome. In The Hidden Oracle, Percy states that Annabeth had gone to Boston for "some family emergency"—searching for her cousin Magnus Chase. Annabeth's appearances in crossover shorts with The Kane Chronicles, and in Magnus Chase and the Gods of Asgard make her the only character who has appeared in all three of the Greco-Roman, Egyptian, and Norse mythology series by author Rick Riordan.

Her main weapon is a short celestial bronze knife given to her by Luke. After losing it in The Mark of Athena, she uses a drakon-bone sword given to her by the giant Damasen. Annabeth also uses an invisibility Yankees cap from her mother and a magic shield. At the end of The Battle of the Labyrinth, Daedalus gives Annabeth his incredibly advanced laptop computer.[6]

In the film adaptations, she is portrayed by Alexandra Daddario.

Grover Underwood

Grover Underwood is a satyr who is Percy's best friend. In the books, he has curly brown hair and fur, acne, a wispy beard. His horns grow larger as the series progresses, and he must take increasingly careful measures to hide them and his goat legs while posing as human. He is a vegetarian but also eats tin cans, furniture, and enchiladas. Grover is twenty-eight in the first novel, but because a satyr's lifespan is twice that of a human, he is still physically a teenager. Grover is a very sensitive and nature-conscious person. Like all satyrs, he can sense emotions and "smell" monsters and demigods. As the series progresses, his concern for his friends and pursuit of his goals lead him to take on leadership roles and become more sure of himself. Unlike his demigod friends, Grover is not an orthodox fighter. Instead, he uses reed pipes or a cudgel. [4] In The Battle of the Labyrinth, Grover begins a relationship with the dryad Juniper.

He is first seen in The Lightning Thief, where he is disguised as a human student at Percy's school, serving as his "protector". Grover later reveals that if he completes a protector mission, he will receive his "searcher's license", and leave to look for the missing god Pan, his life's ambition.[3] When Polyphemus captures him in The Sea of Monsters, he forms a psychic bond with Percy, called an empathy link, allowing them a limited degree of telepathic communication across great distances. He uses this ability to guide Percy to his rescue.[7] He eventually finds Pan in The Battle of the Labyrinth, and receives the wild god's spirit. At the end of The Last Olympian, he is named a Lord of the Wild and given a seat on the satyrs' ruling council.

In the film adaptations, Grover is portrayed by Brandon T. Jackson.

Luke Castellan

Luke Castellan is a 19-year-old demigod (in The Lightning Thief), the son of Hermes and May Castellan. Introduced as the friendly head counselor of the Hermes cabin, he is soon revealed to be a servant of Kronos. Luke is resentful of his father, who adhered to the gods' policy of non-interference despite May Castellan's mental illness. Luke runs away from home young and eventually arrives at Camp Half Blood. After the loss of Thalia, a failed quest, and continued silence from his father; his ongoing resentment turns into a strong hatred of not only Hermes, but all the gods. Though described by those who knew him before he joined with Kronos as a nice guy, he later becomes moody and violent.[4]

Luke is described as handsome with sandy hair, blue eyes, and a long scar on his cheek given to him by Ladon. He is first and foremost an excellent swordsman. He even receives a sword named "Backbiter" from his master Kronos at the end of The Lightning Thief. This sword, which is later reforged as Kronos's scythe, has the ability to harm both mortals and monsters. From the demigod Halcyon Green, he receives a celestial bronze knife and diary. Luke later gives this knife to Annabeth with a promise to always remain her family and entrusts the diary to Chiron. From his father he receives a pair of magic flying shoes, which he later curses and gives to Percy Jackson. He has also inherited an ability to open locks with his mind, along with a cunning nature, from his father. Just before giving himself over completely to host the spirit of Kronos, Luke bathes in the River Styx and obtains the invincibility of Achilles.

Though Luke originally serves Kronos willingly, the horrors he witnesses during the Battle of Manhattan convince him to fight against his former master, eventually committing suicide to stop the Titan. By doing this, Luke proves himself to be the "hero" of the Great Prophecy. As he dies, Luke reiterates what another demigod tells Percy earlier: that unclaimed children and unrecognized gods deserve more respect than they have been given.

In the films he is portrayed by Jake Abel. In this version, Luke is also incredibly skilled in unarmed combat, easily overpowering Percy Jackson when the latter was carrying the sword.

Thalia Grace

Thalia Grace is the daughter of Zeus and Beryl Grace, a TV starlet the god met in the 1980s. In The Lost Hero she is revealed to be the older sister of Jason Grace.[8] Due to her mother's abusive nature, Thalia has considered leaving home since she was little, but stays to protect Jason from her mother's antics. However, when Jason is apparently killed during a visit to Sonoma (in actuality, he is merely presented to Hera), Thalia finally runs away at age 9 and stays with Luke Castellan and Annabeth Chase (who is later portrayed by Alexandra Daddario in the movies) until they meet Grover Underwood when she is 12. When the party reaches Camp Half-Blood, Thalia gives her life to hold off pursuing monsters on top of what would later be called Half-Blood Hill. To save Thalia's life, her father transforms her into a pine tree. Her spirit then provides a magical barrier that protects the camp until six years later when it is purged from the pine tree by the Golden Fleece.

Thalia is pursued so fiercely by monsters because she is a violation of the "Big Three Oath", which was a promise between the three eldest male Olympians to have no more children, for fear of "The Great Prophecy" coming true. At the end of The Titan's Curse, she joins the Hunters of Artemis, a band of immortal female archers in service to the goddess Artemis. This freezes her age the night before her sixteenth birthday, taking her out of the running for the prophecy.

Thalia has electric-blue eyes and spiky black hair, and wears dark makeup and punk style clothing. Annabeth remarks that Thalia's personality and character traits—such as her bravery and loyalty—are very similar to Percy's, and the centaur Chiron later says much the same. She also shares some traits with her father Zeus, including sometimes over-the-top pride, confidence, and reactions to betrayal or contradiction. She is also an incredibly skilled warrior, willing to attack even Luke Castellan, recognized as the best swordsman Camp Half-Blood has ever known. Thalia's weapons of choice are at first a shield named Aegis disguised as a silver charm bracelet (this gift from her father causes paralyzing fear in those who see it because the head of Medusa is pictured on the shield), and a spear disguised as a Mace canister. After The Titan's Curse, she uses a bow and hunting knives, but still uses Aegis. Her main "power" is the ability to summon lightning and generate electric shocks. In The Titan's Curse, it is revealed that she has a fear of heights. In The Lost Hero, she makes a minor appearance and embraces her brother Jason for the first time in years, only to learn that he had lost his memory.

In the film Percy Jackson: Sea of Monsters, she is portrayed by Canadian actress Paloma Kwiatkowski. It was shown that the Cyclopes were the ones who attacked her, Annabeth, and Luke outside of Camp Half-Blood.


Tyson is Percy's younger brother. In The Sea of Monsters, he is introduced as Percy's bullied, childish friend. When Percy is forced to take him to Camp Half Blood, it is revealed that he is a baby Cyclops and a son of Poseidon making him Percy's half-brother. Percy is at first resentful of him as a brother, while Annabeth is openly hostile towards him, but both accept him after they get to know him better during a quest to the Sea of Monsters.

Tyson is described as tall with unkempt teeth and fingernails, and brown hair and eye. He is mentally about 8 years old, but fairly intelligent and extremely compassionate. As a son of Poseidon, Tyson has some limited powers over sea creatures and water. As a Cyclops, he is immune to fire and super-strong; has an uncanny ability to mimic voices; has enhanced senses; and can understand the "old tongue" (the language spoken by Gaea to her first children). Tyson also becomes an excellent smith with help from Beckendorf. In The Last Olympian, he proves himself also to be a capable fighter and is named a general of Poseidon's armies. He leads his fellow Cyclopes into the fight with battle cry of "Peanut Butter!"

Tyson is close with several characters and magical creatures in the series. The first is Rainbow the hippocampus. He also befriends the hellhound Mrs. O'Leary. In The Battle of the Labyrinth, Tyson is revealed to be afraid of satyrs, including Percy's friend Grover; he manages to conquer this fear after a quest with Grover, and befriends the satyr. In the Heroes of Olympus series, Tyson also begins a romantic relationship with the harpy Ella.

In the Percy Jackson: Sea of Monsters movie, he is portrayed by Douglas Smith.

Nico di Angelo

Nico di Angelo is first seen in The Titan's Curse, as an unclaimed demigod rescued by Percy, Annabeth, Thalia, and Grover. At the end of the novel, it is revealed that Nico is a son of Hades. Though he appears to be ten years old and therefore a violation of the "Big Three Oath", in reality he and his elder sister Bianca were born sometime in the 1930s, before Hades took the oath; and, after having their memories wiped in the Lethe, stayed in the Lotus Hotel and Casino until the present day.[9] Their mother was Maria di Angelo, daughter of an Italian diplomat. He is a native of Venice, Italy and can speak Italian.

Nico is initially depicted as cheerful and childish, with olive skin and dark hair, and enjoys playing Mythomagic (a Greek-mythology-themed card game similar to Magic: The Gathering). After Nico learns of Bianca's death, he becomes moody and secretive. Afterwards, he becomes pale and shaggy-haired, always wearing dark clothing. Nico, despite being very powerful, is extremely lonely, much like his father. He makes many other characters uncomfortable, in part due to his powers over darkness and death and his unnerving weapon of choice: a sword made of iron cooled in the Styx ("Stygian iron") capable of absorbing monsters' essences, rather than simply banishing them to Tartarus. Nico initially blames Percy Jackson for Bianca's death, but forgives Percy after learning that holding grudges is likely his fatal flaw. From this point on until meeting Cupid in The House of Hades, Nico struggles to hide his homosexuality, something he was raised to believe was completely inappropriate. At the end of The Blood of Olympus, he begins a relationship with Will Solace.

Nico's suggestion that Percy take on the curse of Achilles and his work to convince Hades to fight in The Last Olympian are crucial to the Olympians' success, and earn him a short bout of fame. He was also privy to the fact that there were two camps, one Greek and one Roman, before The Lost Hero, which makes him an important liaison between the two groups in the latter series. He brings Hazel Levesque, daughter of Pluto and his half-sister, back from the dead and established her at Camp Jupiter. Between The Son of Neptune and The Mark of Athena, Nico travels through Tartarus to find the monstrous side of the Doors of Death, an experience which leaves him haunted and weak. In The Blood of Olympus, he nearly dies several times while "shadow-traveling" the Athena Parthenos back to camp Half-Blood.

The character Nico was named after one of Riordan's former students.[10]

Rachel Elizabeth Dare

Rachel is a main character in the later books of the Percy Jackson series and a minor character in the Heroes of Olympus series. Rachel is a mortal girl who can see through the Mist, the force that obscures gods and monsters from most mortals. She first meets Percy in The Titan's Curse at the Hoover Dam.[9] In The Battle of the Labyrinth, she helps Annabeth and Percy by guiding them through the Labyrinth to Daedalus's workshop. It is hinted throughout the series that she harbors some romantic feelings for Percy; Annabeth notices this and becomes jealous.[6] In The Last Olympian, she begins having strange visions and becomes the new Oracle of Delphi. Her first act as the Oracle is to deliver the next Great Prophecy about seven heroes, setting the plot of the Heroes of Olympus series. Her appearances in the sequel series is sparse; she is contacted by Annabeth in The House of Hades to ask for Reyna's assistance to bring the Athena Parthenos back to Camp Half-Blood.

Following the loss of Delphi to Python, as revealed in The Hidden Oracle, Rachel stops visiting Camp Half-Blood and begins in a frenzied attempt to regain her foresight, not helped by the disappearance of Apollo. Once informed of Apollo's arrival at Camp Half-Blood, Rachel returns and learns that not only Delphi is lost, so do three other Oracles, except for Dodona, which is owned by Rhea. She becomes upset upon learning of the existence of other Oracles, as Apollo has not told her before.

She is described as having red hair and freckles. She is skilled at painting and drawing, with both feet and hands, and is occasionally shown as a non-ADHD foil for her demigod teammates. Percy remarks on her ability to stand still for long periods of time at a charity event. Due to her limited power of foresight, Rachel knows a great deal of knowledge before she learns it herself; during her meeting with Reyna, she states the latter's full name, something that only Reyna's inner circle of friends know.

Clarisse La Rue

A daughter of Ares and the lead counselor of the Ares cabin at Camp Half-Blood, Clarisse is hot-tempered, courageous, and strong. As the child of a war god, she is an excellent fighter (usually utilizing an electric spear given to her by Ares) and a good military strategist. She can be stubborn and overconfident, much like her father, but often surprises other characters with her loyalty and leadership skills. Despite their similarities, Clarisse has a fear of her father and his anger at her if she should ever disappoint him—this, along with a strong sense of honor and pride, often motivates her actions. She also fears the Labyrinth because of what happened to the demigod Chris Rodriguez when he was inside the huge maze. She is aggressive towards most demigods, including Percy Jackson, though she does respect and make friends with a few: Percy, Annabeth Chase, and Silena Beauregard included. She eventually starts dating Chris Rodriguez.

Clarisse makes frequent appearances throughout the novels, first seen just after Percy Jackson arrives at Camp Half-Blood.[4] In The Sea of Monsters, Clarisse is instrumental in bringing the Golden Fleece to camp. She is a main character in the short story "Percy Jackson and the Stolen Chariot" (published in Percy Jackson & the Olympians: The Demigod Files). In The Last Olympian, Clarisse initially sits out the war for Olympus due to a personal feud (like Achilles in the Trojan War). Enraged after the loss of her friend Silena, she later joins the battle with a fury reminiscent of her father's, slaying a drakon singlehandedly and receiving the blessing of Ares.[11] In The Blood of Olympus, Clarisse leads the Greeks in battle to defend the camp.

In The Hidden Oracle, it is stated that Clarisse has gone to attend the University of Arizona.

In the film adaptation, Clarisse is portrayed by Leven Rambin.

The Heroes of Olympus main characters

Leo Valdez

Leo Valdez is a 15-year-old demigod son of Hephaestus and the one of seven protagonists of The Heroes of Olympus. Leo is described as looking like a "Latino Santa's elf" with curly hair, brown eyes, a cheerful face, a slim build, and a mischievous smile. He is Hispanic-American and a native of Texas. He speaks Spanish. Leo has the ability to create and manipulate fire, a skill that no son of Hephaestus has had in 400 years. Leo is also an excellent mechanic. He repairs a bronze dragon running wild in the camp's woods, renaming it Festus. He also creates the Argo II, a ship the Seven sail on to reach Greece.[8]

When he was eight, he accidentally set fire to his mother Esperanza's machine shop while facing off against Gaea, which resulted in Esperanza's death. Leo's remaining family blamed him for killing his only parent and left him a foster child and runaway. Leo also uses his sarcasm and wit to hide his feelings, especially in regards to having been the cause of his mother's death. He has a tendency to think of himself as a "seventh wheel", though he proves no less important or skilled than the others. In The Mark of Athena, Hazel Levesque learns her former boyfriend, Sammy, was Leo's great-grandfather.[5] Until he falls in love with Calypso in The House of Hades, Leo falls quickly for almost any attractive girl he meets.[12]

In The Blood of Olympus, Leo sacrifices himself to annihilate Gaea, and dies in the process. He is brought back to life using the "Physician's Cure" and returns for Calypso on her island of Ogygia.[1] Following his resurrection, Leo goes on a journey with Calypso. As Leo is included in the prophecy of the Grove of Dodona, he accepts the task to accompany Apollo on his trials in The Trials of Apollo, together with Calypso.[13]

Piper McLean

Piper McLean is a daughter of Aphrodite and the famous actor Tristan McLean. She is fifteen in The Lost Hero. Unlike most children of Aphrodite, Piper is not particularly concerned with beauty or fashion. Piper is Cherokee on her father's side. She has tan skin, eyes that change color constantly, and choppy caramel/chocolate-colored hair which she cuts herself. She is slim build and of average height. Her demigod "powers" include "charmspeak" (essentially, magical persuasion) and the ability to speak French. She is also occasionally able to see visions in her magic dagger Katoptris (meaning looking glass in Ancient Greek), which once belonged to Helen of Troy. It is unclear whether this is due to the knife's magic or her own.

Piper's relationship with her father is mutually affectionate but strained, in part because of the small amount of attention he spares for her. When she was young, Piper used her persuasive skills to "borrow" things (such as a car, lawn mower, etc.) just to earn a little of his time. After he is kidnapped by the giant Enceladus in The Lost Hero and subsequently rescued by Piper, Jason Grace, and Leo Valdez; Mr. McLean's relationship with his daughter begins to improve.[8] Piper is also very close to another character: Jason Grace. Though she later learns it was all a trick of the Mist, she was once his girlfriend while they attended the same school. She works hard to recreate this relationship in real life when she comes to Camp Half-Blood. She is also friends with all of the seven quest members in The Heroes of Olympus, especially Annabeth Chase.

Piper's main weapon is her dagger Katoptris, though she later acquires a magic cornucopia and uses it as a weapon. After being captured by pirates in The House of Hades, Piper asks Hazel Levesque to teach her sword fighting, using a jagged celestial bronze sword taken from one of the Boreads.[12]

In The Hidden Oracle, Nico mentions that Piper is currently attending school in Los Angeles, together with Jason.

Jason Grace

Jason Grace is a son of Jupiter and the mortal Beryl Grace, a TV star of the 1980s, and the younger brother of Thalia Grace. Jason has few memories of his mother, who was compelled to give him up when he was two, but he remembers enough about Thalia to not be surprised when he sees her again, in The Lost Hero. Thalia reveals that their mother told her that Jason was dead, and that this was what finally drove her to leave home, after she run away from home and found "Camp Half-Blood . He later discovers, in The Blood of Olympus, that Beryl Grace had become a mania, or spirit of madness. He grew up at Camp Jupiter, the Roman equivalent of Camp Half-Blood, where demigods born to the Olympians' Roman aspects receive their training. In The Lost Hero, he begins a romantic relationship with the demigod Piper McLean.

Jason is described as having blond hair, blue eyes, and a scar above his upper lip (according to Thalia, this is the result of an attempt to eat a stapler when he was two). He is of above-average height, with an athletic build and muscular arms. He has a tattoo burned under his forearm, with twelve straight lines like a bar code, an eagle, and the letters SPQR over the lines. The tattoo symbolizes his twelve years of service in the Twelfth Legion Fulminata at Camp Jupiter; the eagle is a symbol of Jupiter.[8] By the age of fifteen, he had earned the rank of praetor and led the legion with his longtime quest partner, Reyna. Jason also coordinated the Roman camp's attack on the Titan force. He led an assault against Mount Othrys, a Titan stronghold near San Francisco, and defeated the Titan Krios in combat, much as Percy Jackson defeated Kronos.[8]

Of all the characters in the series, Jason is the one who struggles the most with the differences between the Greek and Roman perspectives. Piper McLean describes Jason as very rule- and duty-oriented, though the Roman god Terminus describes him as a "rule-flouter." However, when his former compatriot Reyna sees him again in The Mark of Athena, she comments that he seems to have lost some of his Roman qualities. When the Argo II is stuck in North Africa, he realizes that he must choose one identity or the other. He chooses to consider himself a Greek, despite his parentage, and is later unable to command a legion of ghosts sworn to obey only Roman officers.[5] During The House of Hades it is revealed that Jason has plans to return to Camp Jupiter to improve it with things he learned at Camp Half-Blood, such as giving the fauns (the Roman equivalent of a satyr) more rights and responsibilities.[12] Later, during The Blood of Olympus, Jason decides to consider both the Greek and Roman traditions as part of his heritage.[1] He becomes "Pontifex Maximus", a role which will see him travel between Camp Half-Blood and Camp Jupiter to build shrines for every god and goddess in the pantheon, allowing him to stay in touch with both sides.

Although Jason and Percy immediately recognize that it is best to work together, and become friends, their relationship is not without antagonism. As Percy puts it, it is natural for two powerful demigods to wonder which of them is stronger after a fight. Jason is a sword fighter like Percy, though they have different fighting styles. Jason uses an Imperial gold sword, styled as a Roman gladius, which he can extend into a pilum at will. It is possible that this is a trait common to all Roman demigods, as Reyna is also shown as able to turn her sword into a pilum. Jason also has power over air currents and can fly. He can sense and control some air spirits and has, like Thalia,called down lightning, which he conducts through his Imperial Gold weapons, even underwater.[1] On one occasion, he and Percy together summon a hurricane in Charleston harbor. Like his sister, Jason can also emit static shocks, which seem to be tied to his emotions.

The Hidden Oracle reveals that Jason has been attending school in Los Angeles with Piper, as per Nico's words.

Hazel Levesque

Hazel Levesque is a thirteen-year-old demigod, a daughter of Pluto and Marie Levesque. She first appears in The Son of Neptune, at Camp Jupiter. It is later revealed that she has returned from the dead, assisted by her brother. She grew up in the 1940s in New Orleans, where her mother had a gris-gris shop. When she was born, Pluto offered to grant her mother a wish, but her request for wealth backfired into an ability to control precious metals and gems, which both first view as a curse. Hazel died after Gaea tries to use Hazel's power over earth to resurrect Alcyoneus. When Hazel's mother changes her mind about helping Gaea, Hazel buries herself and her mother under the earth, delaying Alcyoneus's rebirth and killing them both. While Hazel's spirit is being judged, she gives up the chance to go to Elysium to save her mother from punishment, and they are both sent to the Fields of Asphodel instead. At some point before The Lost Hero, Nico di Angelo finds Hazel in the Underworld while investigating an imbalance between life and death. He helps her escape to the world of the living and arranges for her to join Camp Jupiter. Hazel and Nico are protective of each other, much as true half-siblings.

Hazel is described as African American, having cocoa-colored skin, curly cinnamon-brown hair, and golden eyes. Her legion tattoo is described as looking like a cross with curved arms and a head. She eventually learns to manipulate her curse, manipulating precious stones and metals and sensing structures underground. She is an accomplished horse-rider and skilled with a spatha. She tames the horse Arion, who eats precious metals. She is unusually knowledgeable about the Underworld because of her time there. During The House of Hades the goddess Hecate insists Hazel learn to manipulate the Mist. Hazel becomes very gifted at this. After the Second Gigantomachy, Hazel is promoted to the rank of centurion of the Fifth Cohort, succeeding her boyfriend Frank.

Frank Zhang

Frank Zhang is a 16-year-old demigod, son of Mars and a Chinese-Canadian "legacy" (descendant of a demigod) who dies during military service in Afghanistan. He is taken care of by his grandmother after his mother's death, and makes his way to Camp Jupiter upon her insistence. Frank's family descends from Periclymenus, a grandson of Poseidon, who had the power to shapeshift. Periclymenus's descendants were sold into slavery in China, and migrated to Canada many years later. While battling Alcyoneus (who is invincible within Alaska), Frank taps into his ancestral power and transforms into an elephant. However, his combined power of being a son of Mars and having the ability to shapeshift makes his life very fragile. The Fates tied his life force to a piece of firewood when he was a baby....if the wood burns up, he will die (as in the ancient Greek legend of Meleager). The goddess Juno appears to his mother and grandmother while he is a baby to warn them of this fact, as he would be crucial to defeating the Giants. In all his life, Frank has ignited the wood twice, which he can do simply by thinking about it; the first time is while he is finding his way to Camp Jupiter, in bitter cold. The second time is when he, Percy, and Hazel travel to Alaska to free Thanatos. Eventually, Frank entrusts the firewood to Hazel, and in The House of Hades, Leo creates a fireproof pouch to contain it.

Frank has a meek disposition and is uncomfortable upon learning his father's identity publicly in front of the whole of Camp Jupiter. He suspected himself a son of Apollo, given his skill with a bow and arrow. On his quest in The Son of Neptune, and later during the series as well, he uses an enchanted spear given to him by Mars. To Frank's surprise, the spear summons a skeleton warrior that defeats the basilisks. Frank calls this skeleton "Gray".

As he has been residing in Camp Jupiter for no more than a year, Frank is initially considered a probatio, or rookie, of the Fifth Cohort. Before the quest to free Thanatos, however, his cohort's centurion, Gwen, decides to retire and give her position to Frank. Later, in The House of Hades, Jason surrenders his praetorship to Frank, who uses its authority and the Diocletian's Scepter to lead an army of Roman skeleton soldiers against the monsters in the Necromanteion.

Frank was described as 'cuddly' and 'fuzzy' and with a chubby, babyish face in The Mark of Athena, but in The House of Hades, after summoning the blessing of Ares to defeat a hoard of enemies, he transforms. He is then described as being taller, more muscular, and without all his childhood fat. Though now built like a professional football player, he is still as sensitive as before, and is embarrassed at his new appearance at first.

Initially, he was wary of the tension between Hazel and Leo, as Leo reminded Hazel of her old boyfriend, Sammy Valdez. After Leo's encounter with Calypso, however, Leo became more relaxed around Hazel and there were no more signs of anything other than friendship, much to Frank's relief. He then pursues a relationship with Hazel.

Reyna Avila Ramírez-Arellano

Reyna Avila Ramírez-Arellano is 16 year-old Puerto Rican demigod. She is a daughter of Bellona and the younger sister of Queen Hylla of the Amazons. She and her sister worked for Circe during the events of The Sea of Monsters. She is described as intimidating and a natural leader; she has glossy black hair and black eyes. Reyna is generally more used to responsibility than other demigods, as she is a praetor at Camp Jupiter.[8] Reyna's demigod "power" is the ability to lend her energy, skills, and character traits to nearby demigods. Like Leo Valdez, she can speak both English and Spanish. Reyna is often accompanied by two magical dogs, Aurum and Argentum, or by her pegasus Scipio ("Skippy" dies at the end of The House of Hades).[12] The immortal winged-horse named Pegasus awards her the title of "Horse Friend", because of her kindness towards Scipio and other of his descendants.

In The Blood of Olympus she, Nico, and Coach Hedge go on a quest to return the Athena Parthenos to Camp Half-Blood. While shadow-travelling to New York, the trio stops in San Juan and visits Reyna's former house, haunted by the ghosts of her relatives. There Reyna reveals that the Ramirez-Arellano family (which includes Roberto Cofresi and Captain Marion Frederic Ramirez de Arellano) has always been favored by Bellona. Reyna's father (an Iraqi war veteran) deeply loved with the goddess, but his PTSD turned this love into an unhealthy paranoia. When Reyna was ten years old, he became a mania, or evil insane ghost. When the mania attacked Hylla, young Reyna picked up the closest weapon and killed what remained of her father. Reyna is reluctant to discuss the incident because patricide is "unforgivable" in New Rome.[1]

Coach Gleeson Hedge

Gleeson Hedge is a satyr first mentioned in The Last Olympian, as the author of a distress call sent to Grover Underwood. Like Grover, Hedge is also a demigod Protector; his proudest "recruit" being Clarisse La Rue. He disguises himself as a coach at the Wilderness School to escort Piper McLean and Leo Valdez (and later, Jason Grace) to Camp Half-Blood. He also serves as the adult chaperone for the Argo II and later accompanies the Athena Parthenos to camp. Despite his often warlike and often overly-aggressive attitude, Hedge is kind and understanding to campers in need. He enjoys extreme sports and martial arts movies. In The Lost Hero, Hedge falls in love with Mellie the cloud nymph (assistant to Aeolous) and marries her; by the time of The House of Hades, Mellie is pregnant with a satyr boy. Chuck, the baby, is born at the end of book five, with Clarisse as his godmother. In The Hidden Oracle, Hedge, Mellie, Chuck, Piper, and Jason are spending the winter in Los Angeles.

The Trials of Apollo main characters

Lester Papadopoulos

Lester Papadopoulos is the mortal form of the god Apollo and the main protagonist of The Trials of Apollo series.

In The Heroes of Olympus, Apollo's descendant Octavian promises the god many things for blessing his prophetic skills, which leads to the Olympians' distraction from the true threat of Gaea, and to the resurgence of Python. As a result, the Delphic Oracle ceases to function, effectively halting demigod quests, and the Zeus punishes Apollo. Zeus's punishment consists of making Apollo mortal, though he retains most of his personality and some more minor powers. This punishment is revealed in The Trials of Apollo series.

Following a meeting with two thugs, Lester encounters a demigod called Meg McCaffrey who claims him as her servant until he regains his godhood. There, Apollo has to adjust himself to a life of mortality and questing to regain his former powers and lifestyle. Apollo is released by Meg after the revelation of her alliance with his enemy.

Lester is a 16-year-old teenager with curly brown hair, blue eyes, acne, and a flabby torso. He is narcissistic, prideful, and arrogant, but does his best to not be a burden on others. His mortal transformation has made him realize how miserable humans are in facing the gods. In particular, he grows to deeply care for Meg, and resolves to be with her despite the difficulties involved.[13]

Meg McCaffrey

Margaret (Meg) McCaffrey is a 12-year-demigod daughter of Demeter and a main character in The Hidden Oracle. Her father was murdered by "the Beast" and she was subsequently adopted by Emperor Nero, unaware that the two are the same person. Nero taught her the arts of demigod and gave her a pair of crescent rings which can transform into sickles made of imperial gold, before giving her a task to lure Apollo into the Grove of Dodona. Meg appears to Apollo at an alley of Hell's Kitchen, Manhattan to defeat the thugs, also sent by Nero, to stage "robbery". Meg demands Apollo's servitude and with him travels to Camp Half-Blood with Percy's assistance. There, Meg displays unusual abilities even before Demeter claims her, and later goes with Apollo to search for missing demigods and the Grove in the nearby woods, having to endure a brief abduction in the process. Her relationship with Nero is revealed at the climax, but her growing doubtfulness regarding Nero's ways, not to mention her already familiar friendship with Apollo, leads her to rob Nero of his chance on burning the Grove. While she helps Apollo bring the Grove alive, she severs their bonding spell and leaves.

Meg is described as small and pudgy, with dark hair chopped in a messy pageboy style and black cat-eye glasses with rhinestones glittering in the corners. She is perky and adventurous, full of questions, and is also confrontational. She poses questions with no subtlety, something that Apollo is annoyed with but later comes to regard as a unique trait. Her abilities as Demeter's daughter allows her to connect better with nature as well as summoning a karpoi (crop spirit) called Peaches (a spirit of peach trees), a power that none of Demeter's other children demigods are known to possess.[13]

Will Solace

Will Solace becomes the head of the Apollo cabin after the death of Michael Yew during the second Titanomachy. He is a native of Austin, Texas, the son of Apollo and an alt-country singer named Naomi Solace. In The Last Olympian, he uses his father's healing gift to help cure Annabeth Chase.[11] In The Blood of Olympus, Will is revealed to possess the ability to produce sonic waves in addition to his healing-related gifts. At the end of the series, it is implied that he begins a relationship with Nico di Angelo. He refers to Nico as his boyfriend in The Hidden Oracle, after helping heal Lester.[13]

Austin Lake

Austin Lake is a teenage son of Apollo, an accomplished African-American with musician, specializing in jazz saxophone. His mother, Latricia Lake, is a music professor at Oberlin College in Oberlin, Ohio whose music theory class Apollo once took. He is mentioned in The Last Olympian, where he is seen fighting alongside his brothers and sisters of the Apollo Cabin. He serves as a major character The Hidden Oracle, where his and Kayla's abductions in the woods by Nero prompt Apollo to rescue them. Austin's inherited talents are primarily musical.[13]

Kayla Knowles

Kayla Knowles is a daughter of Apollo first mentioned in The Last Olympian carrying out the orders of Michael Yew. She is a major character in The Hidden Oracle, and is abducted by Nero. Kayla's mortal father is a Canadian archery coach named Darren Knowles. Kayla's inherited gift is archery.[13]


Harley is a son of Hephaestus, first seen in The Lost Hero. He is eight years old at the time of The Hidden Oracle, but very muscular. Harley has been trying to locate Leo, his older half-brother, with a magical beacon ever since his disappearance in the aftermath of the Second Gigantomachy.[13]

Triumvirate Holdings

Triumvirate Holdings is a company that is led by three beings who are said to be the worst Roman Emperors in history. They force other people to worship them. During the Second Titanomachy, Triumvirate Holdings was responsible for giving Luke Castellan and his allies with the Princess Andromeda, weapons, helicopters, and top human mercenaries. During the Second Gigantomachy, Triumvirate Holdings supplied Octavian with different weapons. Rachel Dare described Triumvirate Holdings to be so rich that they make her father's company "look like a kid's lemonade stand."

Among the known members of Triumvirate Holdings are:

Greco-Roman deities

Twelve Olympians

Though not all the gods who appear in Rick Riordan's novels are truly Olympians (that is, gods who live on Mt. Olympus), all Greek and Roman gods are generally considered to be a subset of the Twelve Olympians. As such, most characters in the series refer to these immortals generally as the "Olympian gods", to distinguish them from the Greco-Roman primordial gods and Titans.

In the film adaptations, Hermes is played by Dylan Neal in the first film and by Nathan Fillion in the second.
Minor Greco-Roman gods
  • Rhea Silvia – Rhea Silvia is a former Vestal Virgin who mothered Romulus and Remus, the founders of Rome. She was made an immortal and wife of Tiberinus after she was given a death sentence for breaking her chastity vow. In The Mark of Athena, Rhea Silvia and Tiberinus give advice to Annabeth about the location of the Athena Parthenos. She is described as looking like Audrey Hepburn.

Primordial deities

The Primordial Deities are the deities that came before the Titans and the Olympians came into existence. Among the known Primordial Deities are:


The Titans are the children of Gaia and Uranus. Most of them fought against the Gods during the Titanomachy which ended with the Gods winning. Among the featured Titans are:


The Gigantes (also known as the Great Giants) are a race of giant beings that were made by Gaia and Tartarus to overthrow Olympus. They were previously defeated by the Gods and Heracles during the Giantomachy. Each was meant to oppose a specific god. They can only be defeated by a gods and heroes working together. They are mostly described as very tall with dragon-like legs and shaggy hair with different objects braided into it.


The following demigod characters all have one parent who is a Greek or Roman god (or, more rarely, a Titan), while the other parent is a mortal human. It is common for these "half-bloods", as they are known, to grow up unaware that they are not entirely human. They are frequently referred to by gods and other mythological beings as "mortals", though they are certainly more than human.

Historic demigods

In this franchise, different historic people are mentioned to have Greek Gods as their parents or are otherwise involved with the series. Among the known historical demigods are:


The following are mentioned not as direct children of the Olympians, but as grandchildren, great-grandchildren, or the like:

Mythological figures

The following characters from Greek mythology appear in this series. Most of them are the direct children of gods or Titans, but a few are mortals with such great power that they are able to influence the realm of the gods.

Other Greco-Roman beings

Greco-Roman humanoids

Many of the beings and creatures of Greco-Roman myths are humanoid—in other words, they possess both the intelligence and some of the physical features of humans. The vast majority of these creatures are friendly, such as nymphs and centaurs. Unlike the majority of Greek creatures, these beings are also unquestionably sentient and tend to have larger roles in the novel series.

Greco-Roman creatures

The Kane Chronicles

Main characters

Carter Kane

Main article: Carter Kane

Carter Kane is one of two main protagonists and narrators; a descendant of Narmer and of Ramses the Great. He is the son of Julius and Ruby Kane. After the death of his mother (when he was eight years old), he spent six years travelling the world with his Egyptologist father. After his father is captured by the god Set during The Red Pyramid, Carter spends most of his time with his sister Sadie and uncle Amos Kane. He becomes the host of Horus in the first novel, and often collaborates with and receives advice from the god. He also develops a romantic relationship with the shabti of magician Zia Rashid, and subsequently spends much of his time trying to find the real Zia and demonstrate his feelings toward her. Like his father, Carter has dark skin and hair, quite different from both his mother and sister. When living with his father, Carter dressed "impeccably" like Julius even when relaxing, but adopts a much more casual style when he goes to live at Brooklyn House. Though he is not one to flout rules, Carter is brave and courageous enough to pursue the way of the gods despite the House of Life's disapproval. His specialty is combat magic; his preferred weapon a khopesh. He is often given leadership responsibilities and struggles to accept his role, until he willingly becomes pharaoh of the House of Life during The Serpent's Shadow.

Sadie Kane

Sadie Kane is one of two main protagonists and narrators; the younger sister of Carter Kane. She is left in the care of her non-magical grandparents in London after the death of their mother Ruby Kane. Though she is able to live a "normal" life, something her brother is occasionally jealous of, her unusual circumstances make her sometimes jealous of Carter (especially when she is reminded of his exotic lifestyle). Sadie has to abruptly leave her life in London when she goes to revive the twenty-first Nome and fight Set after the god captures her father, Julius Kane. Sadie becomes the host of Isis in The Red Pyramid and continues to study the goddess's path throughout the series. She also becomes romantically involved with one of the Brooklyn House initiates Walt Stone and also with the god Anubis, though her relationship with either is not formalised until after Walt becomes the "eye" of Anubis in The Serpent's Shadow.

She has caramel-colored hair and light skin, traits inherited from her mother Ruby. Unlike Carter, Sadie is rebellious and bold (also like her mother) and acts the part; often making snap decisions, ignoring rules, and choosing to wear clothing to display her personality rather than to conform or aid her magic. Her magical speciality is with spells, potions, and hieroglyphics.

Walt Stone

Walt Stone is one of the twenty-first Nome's initiates, who arrives at Brooklyn House sometime between the first and second novels. He has dark skin and is from Seattle, where he lived with his mother. Walt is a sau, or charmmaker.[17] In The Throne of Fire, it is revealed that Walt has inherited a deadly curse from his ancestor Akhenaten, which will kill him before reaches adulthood, as it did to his father and their famous ancestor King Tut. The curse progresses more quickly when he uses magic, which is why he specializes in charms and also why he begins to call on the god Anubis for guidance. In The Serpent's Shadow, Walt finally succumbs to the curse, but as he dies he allows himself to become the host of Anubis, whose spirit can essentially keep him alive. Both Anubis and Walt Stone have romantic feelings for Sadie Kane, and this is part of the reason why the two "fuse" successfully.

Zia Rashid

Zia Rashid is a magician from the first Nome who was born and raised in Egypt. She is found and raised by Iskandar, the Chief Lector, after the destruction of her hometown by Apophis. When Julius Kane released five gods through the Rosetta Stone, she became the unexpected host of Nephthys, and was subsequently placed by Iskandar in an underwater prison so the House of Life could not eliminate her. A shabti of her was created to take her place; it is destroyed during the fight with Set in The Red Pyramid. Carter Kane falls in love with this shabti and seeks out the real Zia to free her and release Nephthys's spirit. Zia, who specializes in fire magic, later becomes the host of Ra and the two manage to destroy Apophis in The Serpent's Shadow. Her initial indifference to Carter slowly evolves into romance, and the two begin dating at the end of the series when Ra ascends back to the heavens.

Amos Kane

Amos Kane is Julius Kane's younger brother, Carter and Sadie's uncle, and the leader of the twenty-first Nome (New York). He takes in Carter and Sadie after Julius hosts Osiris and is trapped by the god Set. During the first novel, Amos is possessed by Set and forced to lure his niece and nephew to the god's pyramid in Phoenix, Arizona. Once freed, Amos goes for healing at the first Nome, and does not return to Brooklyn House until the second novel. His experience hosting Set has changed him, however, and eventually leads to his highly-controversial decision to voluntarily host the god during the final battle with Apophis. Amos succeeds Michel Desjardins when the former leader of the House of Life sacrifices himself fighting Apophis.


Iskandar is the Chief Lector of the House of Life. Born in the 1st century BCE, during the reign of Cleopatra VII, he witnessed the end of the Egyptian monarchy and the absorption of Egypt into the Roman Empire. He came to believe this was the fault of the gods and ended the House's policy of calling upon them; Ruby Kane's vision of Apophis rising changes his mind, but it is too late for him to make any real change. He was the one who saved Zia after her village's destruction and, sensing that she holds the power to host Ra, arranged for her confinement in an underwater prison under the watch of Nephthys while creating a shabti of her to protect Carter and Sadie, both of whom also hold the potential to become hosts of gods. Shortly after meeting them, he dies in his sleep, knowing that these three can make a change where he could not. He is succeeded by Michel Desjardins as the House's leader.

Michel Desjardins

Michel Desjardins is the lesser antagonist and leader of the House of Life after the death of Iskandar. Desjardins is approximately 200 years old, considered "young" for a magician, and as such has known only the House policy of exterminating the gods. He is therefore at first opposed to cooperation with the gods. He works with Vladimir Menshikov in the latter's attempt to hunt Sadie and Carter Kane, but he chooses to sacrifice himself execrating Apophis when he learns of the chaos serpent's rising and Menshikov's attempt at a form of mind control. He is succeeded as leader of the House of Life by Amos Kane.

Magnus Chase and the Gods of Asgard

Main characters

Magnus Chase

Magnus Chase is the main protagonist of the series. A 16-year-old Bostonian teenager, Magnus lost his mother Natalie to a mysterious wolf attack two years prior to the events of The Sword of Summer and is forced to live in the streets with his homeless friends, Blitz and Hearth. On his 16th birthday, his uncle, Randolph informs him of his divine parentage as a son of a Norse god and his inheritance of Sumarbrander, the sword that once belonged to his father, Frey. After being killed by Surt, a fire giant, Magnus is then sent to Hotel Valhalla by Sam, a Valkyrie. He then finds out that his father is Frey, the god of peace and prosperity, who belongs to the Vanir tribe of Norse deities.

Magnus is described as having parted blond hair that reaches his chin and haunting gray eyes that resemble his cousin's, Annabeth. He is said to look like Kurt Cobain and has asthma. His scrawny look is replaced by a more muscular persona after his death and acceptance to Valhalla. He is quite street smart due to the two years he spent as a homeless man and as a result, is not quick to trust people. Nevertheless, he considers Blitz and Hearth as the only friends he is completely loyal to, and after a while, also begins to ease up and trust Sam. He is also known to have a bonding relationship with another daughter of Loki named Alex Fierro. He is not fiery and quick to anger.

As a son of the god of fertility, Magnus does not excel in offensive power. Instead, he usually thinks a strategy to safely escape from a danger. When he does have to attack, he mainly uses the Sword of Summer, Jack, whom he usually lets go by himself. Magnus' demigod abilities concern healing and warmth: through concentration, Magnus is able to heal even the mortally injured as well making a mortal see through Ginnungagap and thus the Norse world, though doing so often causes him to read the subject's memories.


Blitzen (Blitz) is a 20-year-old dwarf or, more specifically, a svartalf from Nidavellir. He has dark skin and hair, and has a beard. He is the son of a Vanir, Freya, making him Magnus' cousin, and a dwarf, Bilì, who was eaten by Fenris Wolf while checking Fenris's prison rope. He is sent alongside Hearth by Mimir to watch and protect Magnus. Though he keeps it up for two years, the task fails when Magnus is killed, but Blitz continues to look for him until they are reunited in Valhalla. As a dwarf, Blitz is sensitive to sunlight and will slowly turn to stone if exposed too much, which is why he always wear a copious article of clothing whenever there is sunlight, except in Folkvanger, in which sunlight is replaced by an aura radiated by Freya instead. Instead of forging, Blitz excels in clothing design, making him a laughing stock among his fellow dwarfs, but after he wins a match against Eitri Junior, he becomes respected and eventually opens up a clothing shop. In battle, Blitz uses his creations to assist himself, including chain-mail gloves and vest. Blitz has had a strong relationship with Hearth ever since the former saved the latter's life, and the two are very protective of each other.


Hearthstone (Hearth) is a light elf from Alfheim. He is skinny with fair skin and with short spiky white hair, which, when combined with his black leather jacket, jeans and a red scarf, "makes him look like a character from a Japanese anime". Hearth is deaf and can only communicate with ASL (Alf Sign Language), though he is able to read lips. Since his home world is always bright, he is sensitive to darkness. Like Blitz, Hearth makes a deal with Mimir to drink water from Mimir's Well by one of the roots of Yggdrasil to gain knowledge about runes and in return has to work with him for several years. He becomes a companion and protector of Magnus from then on. Hearth is the first elf in a long time to focus on magic from runes, which he has studied extensively. He can cast various runes, though doing such consumes his energy. Eventually he progresses to the rank of a full sorcerer. Hearth has a traumatic past, as he is effectively unwanted by his parents, who shun him for being deaf and not as great as his brother, Andiron, who died young; he is forced to face his past in the second book, when he has to collect Skofnung Stone from his father, Alderman, who wants him to finish the blood tax imposed on him as repentance for Andiron's death. He is also reminded that sooner or later, he will have to take the othala rune from Andiron's place of death, which he planted as a reminder of his past, to complete his magic arts. His relationship with his friends helps him, though, and he even once calls Magnus "brother". At the end of the first book, Hearth is freed from servitude and begins learning runes at Asgard.

Samirah al-Abbas

Samirah (Sam) al-Abbas is a Valkyrie and a daughter of Loki who selects Magnus as an einherji under Odin's order. She is an Arab American who normally wears her Valkyrie armory and a noticeable green hijab, which also functions as a swan cloak, or an invisibility cloak. As a Valkyrie, Sam is different from Magnus in that she is still alive. She leads a double life as both a Valkyrie and a normal high school student. She does not worship the Norse gods as she already has a God she believes in, though she still has to occasionally work with them. Her family is from Baghdad, Iraq, and Sam is raised by her grandparents after the death of her mother Ayesha. Sam's family already had a long history with the Vikings, even before her mother met Loki; Ahmad ibn Fadlan, an envoy of the Abbasid Caliph to the Kievan Rus', is one of Sam's ancestors, and the Varangians had since intermarried with Sam's family. Her parentage is a shame to both sides of her parents; she is shamed in her mother's family as an out-of-wedlock child, while having Loki as a father makes others view her as suspicious among the Asgardians. Sam has an interest in flying and planes and vows to become a pilot one day, which is why she is very serious about her job as a Valkyrie.

In The Sword of Summer, Sam is expelled from Valhalla when her video of Magnus' heroic death is edited by Gunilla, but later joins Magnus, Blitz, and Hearth in stopping Fenris Wolf from breaking free. She is eventually reinstated as Valkyrie and gets another job as Odin's personal aide. In The Hammer of Thor, Sam is betrothed by Loki to Thrym in exchange for Mjolnir; in reality, Loki wants the Skofnung Sword, with which he can finally free himself. Sam is then given a task by Odin to head towards Scandinavia and personally imprison Loki back before he is able to invade Midgard, and eventually invade Asgard.

As a fighter, Sam excels in using the axe, a weapon of the Valkyries. She also inherits her father's ability to shapeshift into animals such as a horsefly or lion (her surname, al-Abbas, means 'of the Lion' in Arabic); however, it makes her uncomfortable, as it causes her to become more like her father, Loki.


The Sword of Summer (Jack) was Frey's weapon, currently wielded by Magnus Chase. After Magnus finds out that the sword is sentient, Sumarbrander decides to name itself Jack, and be referred to as a male. In battle Magnus can let the sword attack his enemies on its own or use his own strength and control the sword himself. Either way, it is Magnus who loses energy ultimately, though this loss is delayed until he next grips or sheathes Jack.

He bears a grudge against Frey, who 'abandoned' him, by giving him to Skirnir as a price for the latter bringing the former a Giantess with whom he fell in love; he summarises this by once admonishing Frey, saying 'blades before babes'.

He reached Boston with one of Skirnir's descendants during the Viking expansion, where he was lost for centuries till he was recovered by Magnus.

Alex Fierro

Introduced in Magnus Chase and the Hammer of Thor, Alex Fierro is a son of Loki and Mr. Fierro. She is gender-fluid, similar to Loki who was known to change genders in myths. When in Valhalla, she is referred to as an argr, the Old Norse word for Unmanly, due to being born a male but identifying as a woman occasionally. Unlike her half-sister, Sam, Alex was born via Loki's female form, thus making the god her mother rather her father. Like Sam, she resents her mother; however, Alex seems to be able to resist Loki much easier than Sam. She, like Magnus, is homeless due to her family disagreeing with her gender-fluidity.

Alex uses a gold garrote wire as a weapon, which formally used to be a pottery wire. She can also shape-shift into things such as a bear and an elephant in combat, and is far more comfortable with embracing this power than her half-sister, Sam.

Norse deities

The Norse gods fall into two general groups: the Aesir and the Vanir. All are referred to generally as "Asgardians", but the Vanir inhabit Vanaheim as often as Asgard. The Aesir are more warlike, while the Vanir are peaceful. Specifically, however, the gods tend to be distinguished by what side they fought on during the Aesir-vanir war, and not by their personal temperaments.


The following Norse gods are considered the more warlike of the two strains of immortals.


These gods are generally more peaceful and dislike the warlike nature of the Aesir.
