Grover Underwood is a satyr and Percy Jackson's best friend. He has found the four most powerful demigods of the century: Percy Jackson (son of Poseidon), Thalia Grace (daughter of Zeus), and Nico and Bianca di Angelo (children of Hades). Before his death, Pan (the god of nature) says Grover is the bravest satyr ever to be. He names Grover as his successor to carry on his word to protect the wilderness. The Council of Cloven Elders is angered by this choice. He is the boyfriend of the tree nymph Juniper. But in The Last Olympian he is chosen as a replacement for Leneus (another Satyr who died in battle) on The Council of Cloven Elders after.
Tyson[change | change source]
Tyson is a Cyclops, the son of Poseidon and his mother is unknown. Technically he is not a demigod, but at camp he lives in Percy's cabin, and is considered to be Percy's brother. He first appears in The Sea of Monsters as a homeless boy. He is afraid of Grover while Grover is also afraid of him. Also in The Sea of Monsters he was Percy's best friend and was always picked on. At the end of the book, he gets to go to work for his father, Poseidon, in the Underwater Armory.
Nico di Angelo[change | change source]
Nico di Angelo is a son of Hades, Bianca's younger brother and Hazel Levesque half-brother and Percy Jackson and Thalia and Jason Grace's cousin. At first Percy assumed Hades broke the oath not to have children after World War II, but Nico and his sister Bianca had been placed in the Lotus Casino, where 'time stands still' since before the oath was made. At the time, he took great interest in a game called Mythomagic. Nico has the power to raise skeletal warriors, shadow travel, and create great fissures in the ground that swallow up anyone or anything unfortunate enough to be standing on it at the time. For a time, he was Percy's enemy, blaming him for the fact that he had failed to protect Bianca as he had promised, but they became friends eventually. Nico tried multiple times to contact his sister and had difficulty contacting her, even using his dreams. Nico refused to stay at Camp Half-Blood in the fourth book after noting that he was not welcomed at Camp Half-Blood; he compares this to the fact that his father is not welcomed at Olympus. Several months later, he informed Percy of a plan that could lead to defeating Kronos. In the final book of the first series, he convinced Percy to bathe in the River Styx, making him invincible barring the small of his back. In the end of the final book Percy makes all the gods and goddess to 'claim' all their children and make sure they have cabin's in Camp Half-blood. Nico goes back to the camp and makes a cabin for himself and all the other minor gods and goddess. Later in the Heroes of Olympus series,he became captured by to giants [in mark of Athena] though he survived. Through out house of Hades and at the end of blood of Olympus,it is said that Nico has a crush on Percy,though he gives up that dream and goes to Will Solace,the son of Apollo,and in trials of Apollo they are seen as a couple.
Thalia Grace[change | change source]
Thalia Grace is a daughter of Zeus. She is Jason's older sister and the cousin of Percy Jackson and Hazel Levesque and Bianca and Nico di Angelo. Grover Underwood was assigned to watch over her when she ran away from home at ten years old. On her journey, she met Luke Castellan and Annabeth Chase. They also had brief encounters with the Hunters of Artemis and she was enticed to join by Zoë Nightshade. When she was twelve, they were all soon attacked by a herd of monsters and caught by a Cyclops in New York. She was captured, but thanks to Annabeth, was freed. They meet the satyr Grover Underwood on the way. They escaped, but found that the monsters they had briefly escaped caught up to them. As they reached Half-Blood Hill, Thalia sent Luke, Grover, and Annabeth over the boundary line while she faced the monsters. She sacrificed her life for her friends, and her father, Zeus, took pity on her and transformed her to a pine tree. She is later brought back to life by the Golden Fleece and joins the quest in the third book where she ultimately joins the Hunters, taking the place of Zoë Nightshade. She has a younger brother, Jason Grace who was separated from her when she was 10. This became the reason she ran away from home.She wears a lot of dark makeup and punk style clothing. She has electric blue eyes and spiky black hair. She is so like Percy that according to Annabeth, they either could be best friends... or worst enemies.
Luke Castellan[change | change source]
Luke Castellan is one of Hermes's children and a major antagonist of the series. Though initially the counselor of Cabin 11 and an ally to Percy, he revealed his true nature as a high-ranking member of Kronos's army by attempting to kill Percy at the end of The Lightning Thief, and on several occasions afterward. He is shown to harbor a great bitterness towards the gods (particularly his father, Hermes) for what he regards as abandonment. His mother had been driven crazy upon attempting to become the Oracle, leading to a stressful childhood. After reforming, Kronos does not need Luke's assistance. However, in his duel with Percy on Mount Olympus, striking Annabeth reminds him of his promise to protect her. This temporarily frees him from Kronos's influence. Percy makes his choice to give Luke Annabeth's knife, and Luke, cursed by the broken promise, kills himself by stabbing his own Achilles heel to destroy Kronos. This fulfills the prophecy, with Luke being the foretold hero. In the film, Luke is portrayed by Jake Abel. Percy refers to Luke as a hero.
Greek/Roman gods[change | change source]
- Zeus/Jupiter - The King of the Gods, God of the Sky, Zeus is brother to Poseidon and Hades, uncle to Percy, father of Thalia, son of Kronos. His Roman counterpart is Jupiter, brother to Pluto and Neptune, and father to Jason. He is a principal character in the first book but is a minor one in the next four. His cabin is Cabin 1. Poseidon calls Zeus dramatic, saying that he might do better as the God of the Theater. His symbol of power is his Master Bolt. In The Lost Hero, Zeus (under the influence of Khione) forbids contact between gods and mortals and closes down Olympus. Despite this, Zeus indirectly aids the demigods several times on their quest, such as answering his son's prayer for aid against Enceladus.
- Hera/Juno - The Queen of the Gods and the Goddess of Marriage. Hera plays a small role in The Titan's Curse but is one of the gods who help Percy and the others in their quest in The Battle of the Labyrinth. At the end of the book, Annabeth and Percy offend her because she did not care that Luke was gone or that Daedalus and Pan were both dead. She especially dislikes Annabeth and curses her like how Ares cursed Percy in the 1st book. She thought Luke, Pan and Daedalus were better off gone. Cabin 2 at Camp Half-Blood is dedicated to her, but is perpetually empty; as the goddess of marriage, she has not given birth to any demigods. In spite of this, Hera meddles with the affairs of many demigods. In The Last Olympian she has a minor role where she congratulates Percy on his victory rather disdainfully and says that she would have to let him and Annabeth live a little longer. She returns as Juno in The Lost Hero in which Percy Jackson has disappeared. She has been kidnapped by Gaea and contacts Jason Grace, the new protagonist and asks him to help her. It is then revealed that as Juno, she snuck out of Olympus and exchanged Percy and Jason to try and unite the Roman and Greek demigods. She goes against the wishes of Zeus in this regard because she wants to save everyone – gods, demigods and mortals from the new evil. Juno also admits that she is bitter towards heroes and demigods because she does not have any of her own. Juno, Hera's Roman counterpart, is more warrior-like and more disciplined and rebellious. Juno even states that Hera would not have disobeyed Zeus, but Juno would.
- Aphrodite/Venus - The Goddess of Love, Beauty, Lust, etc. She is mentioned in The Lightning Thief and appears briefly in The Titan's Curse. Her children (mostly girls) live in Cabin 10. She wears a red satin dress and has long dark-brown hair in ringlets, though she sometimes wears it down. Her appearance changes as Percy looks at her, matching every female he has ever had a crush on (one being Annabeth). She encourages Percy to pursue a quest for true love. She is shown to have interest in Percy's feelings towards Annabeth and promises to make Percy's love life hard. She appears again at the Council of the Gods and votes to let Percy live. Aphrodite is also the last child of Ouranos. Aphrodite is also the mother of Piper McLean, a main character in The Lost Hero, and changes her daughter's tomboyish appearance twice to make her more beautiful.
- Apollo - The God of the Sun. The campers in Cabin 7 are his children. He drives a flying red convertible, a Maserati Spyder, that glows brightly like the sun. He appears to be about 18 or 19 years old and has sandy colored hair and dazzling white teeth. Apollo wears Ray-Ban sunglasses and sports an iPod. Percy notes that he looks similar to Luke, but less evil. He also loves to recite poetry, especially haikus; Percy describes them as so bad that he would rather be shot by an arrow than listen to one, but Zoe says his limerick days were much worse. Apollo helps Percy and his friends by flying them to Camp Half-Blood in The Titan's Curse and later speeding up a train while being disguised as a homeless man. In The Last Olympian, he heals Annabeth's broken arm after she was thrown into her mother's throne. Apollo is also the god of prophecy and controls the Oracle. At the end of the war between the Titans and the gods, Rachel is certified as the new Oracle by Apollo. His name is both Greek and Roman.
- Ares/Mars - The God of War and Bloodlust. His children are the campers in Cabin 5. He first encounters Percy in The Lightning Thief. Ares drives a large, black, Harley-Davidson motorcycle with a flame-pattern paint job, a boar themed antenna, handles, boars head shaped red headlight and a leather seat made from human skin. He wears red wraparound sunglasses that cover his eyes, which are flames, a bulletproof vest, combat boots, black leather biker clothes, and a black leather duster. His face is covered with scars from many fights. Once, Ares sends Percy, Grover and Annabeth to retrieve his shield, which he left behind after a date with Aphrodite. They travel to a Tunnel of Love, which ends up being a trap set by Hephaestus. He intercepts Zeus's master bolt from Luke in The Lightning Thief and gives Percy a backpack containing it. He wants to cause discord among Zeus, Poseidon and Hades. Later, he is overpowered by Percy in a duel. He curses Percy that his sword will fail him in battle and departs. Ares returns with minor roles in The Sea of Monsters and The Titan's Curse. He is seen at the end of The Last Olympian after giving Clarisse a blessing during battle and is very proud of her.
- Artemis/Diana - The Goddess of the Moon, Wild Animals, and the Hunt. She is the twin sister of Apollo. Cabin 8 at Camp Half-Blood is dedicated to her, though it is unoccupied, except for the rare visits when her group of huntresses stays at the camp, such as in The Titan's Curse. She is a maiden goddess and bears no demigod children. She has a prominent role in The Titan's Curse. Artemis appears to be about 12 years old. She has auburn hair and silvery-yellow eyes, the color of the full moon. Artemis leads a group of teenaged girls known as the Hunters of Artemis. The Hunters pledge to give up love in exchange for immortality. The Hunters never grow up and can only die if they are killed in battle or break their oath. Artemis leaves the Hunters to pursue a monster that has the potential to destroy Olympus. She is trapped by Atlas and is forced to hold up the sky. She is rescued by Percy who holds the sky for her so she can fight Atlas. Artemis and Percy trick Atlas into holding the sky again. Artemis transforms Zoe into a constellation after she is killed in battle. She seems to like Percy, saying that he's okay for a boy, and later refers to him as a man. She speaks up for Percy, Annabeth and Thalia at the Council of the Gods and votes for Percy to live. Thalia joins her hunt at the end of The Titan's Curse, preventing her from fulfilling the Oracle's prophecy. Artemis did not follow Zeus' order to not have contact with mortals by still communicating with her Hunters. Thalia states, "Artemis follows her own rules," even though she does this without Zeus' knowledge. She sent Thalia to find Jason, her long-lost brother.
- Athena/Minerva - The Goddess of Wisdom and Battle Strategy. She first appears in The Titan's Curse, where she is shown to dislike Percy and his relationship with Athena's daughter, Annabeth. Athena is described as being beautiful but also serious and foreboding. She has intense grey eyes, as do almost all of her children who reside in Cabin 6. In The Demigod Files, she has black hair, but in other books, she is depicted as having blonde hair, like her children. Athena considers Percy to be very dangerous as he has the potential of fulfilling the Prophecy that a child of one of the Big Three will destroy Olympus. She advises Percy that wise counsel is not always the most popular, and cautions him about his fatal flaw. She also votes not to let Percy live. Percy considers Athena one of the most dangerous beings he has encountered, noting that because of her calculating intelligence, her plans rarely fail.
- Demeter/Ceres - The Goddess of the Harvest. She is first mentioned in The Sea of Monsters, when Hermes is talking to Percy about the quest. She was also one of the goddesses who voted to keep Percy alive in The Titan's Curse. Demeter made three brief appearances along with her daughter Persephone in The Last Olympian, notably when she participates in the battle against the Titans. Her children reside in Cabin 4.
- Dionysus/Bacchus - The God of Wine and Madness. He is Percy's cousin and the father of Castor and Pollux. He is the director of Camp Half-Blood where he was sent by his father Zeus for chasing an off-limits nymph though he is married. At Camp Half Blood, he is known as "Mr. D." He is shown to hate his job and have a low opinion of demigods stemming from Theseus' abandonment of Ariadne, but he has to remain at Camp Half-Blood for another fifty years (his punishment used to be 100 years, then Zeus shortened it). His children live in Cabin 12. He can be seen playing with the satyrs in camp. He appears in all the books. In The Battle of the Labyrinth, he goes out to search for the minor gods and returns at the end of the book. He rarely bothers to call the campers by their proper names, making a point of calling Percy Jackson names such as "Peter Johnson", "Perry Johannson", or "Pierre Jorgenson" throughout the series. He also calls Annabeth "Annie Bell" or "that Anne girl", regardless of the fact that she has been in Camp Half-Blood since she was seven years old. Though he has said that Percy "always manages to annoy him," he has saved Percy's and Annabeth's life several times.
- Hades/Pluto - The God of the Underworld, son of Kronos, brother to Poseidon and Zeus. He is the husband of his niece Persephone and is Nico and Bianca di Angelo's father. Percy first encounters him in The Lightning Thief on his quest to find and return Zeus's master bolt. In The Last Olympian, Hades traps Percy when Nico leads him to the Underworld palace. He plans to put him in the dungeon until Nico turns sixteen, so Nico can fulfill the prophecy. He appears again with Persephone and Demeter to save Olympus. After the war, Hades, along with the minor gods, is given a cabin in Camp Half- Blood
- Hephaestus/Vulcan - The Gods' Blacksmith and God of Fire. He appears as a minor character in The Titan's Curse and as a major one in The Battle of the Labyrinth where he helps Percy numerous times. His children reside in Cabin 9. He is the father of Charles Beckendorf and Leo Valdez. He was thrown off of Mount Olympus when he was born because Hera thought he was hideous and wanted a "perfect" family, though Hera denies it. Hephaestus says that Hera likes telling the story that Zeus threw him off the cliff because "it makes her seem more likable." He defied Zeus' rule in The Lost Hero and spoke to his son. He also took the head of Festus to Bunker 9 for Leo.
- Hermes/Mercury - The Messenger of the Gods and the God of travelers, Communication, and Thieves. He has nearly no role in the first book but is a significant character in the second book where he helps Percy by giving him a flask full of air, backpacks, and his special multi-vitamins, hoping that he will be able to rescue his son, Luke, who had joined the Titans. He is also mentioned briefly in The Titan's Curse. He is bitter about Luke's situation and gets angry at Annabeth in The Last Olympian for not saving him when she had the choice. All of his children and any half-bloods of undetermined parents stay in Cabin 11.
- Hestia/Vesta - The Goddess of Hearth and Home. She first appears as a young girl, about 8 years old, who wears a simple brown dress and scarf. Percy sees her when he enters Camp Half-Blood for the first time, but does not speak to her. Percy and Nico encounter her in The Last Olympian when she gives them food. She has glowing eyes that remind Percy of a cozy fire. Hestia tends to the hearth in Olympus while the other gods battle Typhon. Hestia gave up her throne for Dionysus in order to prevent a civil war among the Olympians. She explains to Percy that one of the greatest powers is to yield in order to retain peace. Percy offers Pandora's jar to Hestia, as she is the Last Olympian and Hope survives best at the hearth. Hestia accepts, preventing Percy from being tempted to open it. She later helps Percy when he battles Kronos by making her hearth painfully hot for Kronos when he reaches to get his scythe when it fell into the flames. When Percy looks into her eyes, he can sometimes see the past or the future, like what happened before Annabeth, Thalia and Luke came to Camp Half-Blood.
- Poseidon/Neptune - The God of the Sea, Earthquakes, Storms, and Hurricanes and the creator of the horse. He is Percy's father and his children (Percy's half-siblings) reside in Cabin 3. In the first book, he is suspected of having stolen Zeus's master bolt, but Percy proves the claim false. He appears as a minor character in the next three books. In The Last Olympian, Percy falls unconscious in the ocean and lands at Poseidon's castle. Poseidon is at war with Oceanus, the Titan god of the ocean, and makes Percy go back to camp instead of helping him. He is one of the few gods that does not go and help in the effort to defeat Typhon until Percy tells him that the only way to win is to abandon the sea and fight Typhon. His symbol of power is the trident
Minor gods[change | change source]
- Aeolus - The custodian of the Four Winds. They never made an appearance, but they were mentioned in The Last Olympian. They made it hard for the Titan army to hit Olympus by air.

- Amphitrite - The Queen of the Seas, wife of Poseidon, and daughter of Oceanus. In The Last Olympian, Amphitrite alongside Triton is seen talking strategy with her husband Poseidon in the throne room of their ocean floor palace. Percy Jackson joins them and Amphitrite treats him coldly as he is a reminder of Poseidon's unfaithfulness. Percy expects nothing else and feels sorry for her as she does not have a faithful husband.

Later, Annabeth and Percy save Luke, and Luke sacrificies himself.

- Charles Beckendorf - A son of Hephaestus, known to be able to build almost anything. He is lead counselor for Cabin 9. He had a minor role in the first four books in the series, but has a larger role in The Last Olympian. He has a crush on Silena Beauregard, whom he starts dating from the short story The Bronze Dragon contained in The Demigod Files. Most members of Camp Half-Blood call him by his surname, Beckendorf. He sacrifices himself at the beginning of The Last Olympian to destroy the Princess Andromeda, a ship that was Kronos' headquarters, unaware that it was actually because of Silena (a spy on the camp) that he lost his life.
- Christopher - The demigod son of Hephaestus who first appears in The Lost Hero.
- Chris Rodriguez - A half-blood son of Hermes (as shown in "Percy Jackson and The Olympians The Ultimate Guide") who had gone to Kronos's side until having gone completely insane in the Labyrinth. Clarisse finds him and brings him to camp where Dionysus makes him sane again. He later has a relationship with Clarisse.
- Clarisse La Rue - One of the children of Ares and the head of Cabin 5. She is hot-tempered, arrogant, big, tall, strong, and is known to dislike Percy. Despite her brash nature, she is capable of compassion, shown when she cares for Chris Rodriguez, a half-blood who became a traitor and was later found crazed and stumbling within the Labyrinth in a bout of madness. She is later seen holding Chris's hand at a campfire after Dionysus cures him of his madness. She later befriends Silena Beauregard, apparently after Silena gives her advice on her first boyfriend. She and her cabin later fight with the Apollo cabin over a flying chariot. Later, she prevents Cabin 5 from joining in the battle of Manhattan because of the chariot fight, though Michael Yew gives it to them. Silena later impersonates her to bring the Ares cabin into the battle by taking her armor and spear. Silena is killed by a drakon during this charade. To avenge her friend, Clarisse stabs the drakon in the eye, breaking her spear and electrocuting the drakon. She then runs at Kronos's armies, appearing to be as invulnerable as Percy, even though she does not have the Curse of Achilles. Percy recognizes that an aura around her highly resembles that of Ares when Percy fought him. Thalia remarks that it is a blessing of Ares and that she has never seen it before in person. She is later frozen by a giant, and, after thawing, is welcomed to Olympus by her father, who is very proud of her.

He turned to Kronos' side after Percy saved his life by letting him live after a duel. After the duel, he pledges himself to Kronos, the last half blood needed for his resurrection. In The Last Olympian, he tries to stab Percy in the small of his back (his Achilles spot), but Annabeth leaps in front of the dagger, and Kronos believes that he tried to stab Percy's Achilles spot. He is in the truce party along with the Empousa queen and Prometheus. Ethan later figures out that the small of Percy's back was his Achilles spot, but instead of killing him, he tries to kill Kronos. Kronos laughs, and kills him easily. Ethan's last words were "Deserve better...if they the minor gods just...had thrones..."
- Harley - A demigod son of Hephaestus who first appeared in The Lost Hero.
- Jake Mason - A son of Hephaestus. He becomes the head of Hephaestus' cabin after the death of Charles Beckendorf in The Last Olympian. He fights in the war between the gods and Titans.

- Katie Gardner - A daughter of Demeter that is the head counselor for cabin four at Camp Half-Blood, as seen in The Last Olympian. Miranda Gardiner is her deputy taking over in winter because Katie is not a year-rounder. She fights in and survives the war between gods and titans.

She is the cousin of Percy Jackson, Thalia Grace, Nico di Angelo and Bianca di Angelo.
- Lacy - Lacy is a daughter of Aphrodite who befriends Piper McLean in "The Lost Hero".

- Mark - A son of Ares. He is mentioned by Percy once in The Demigod Files in the short story Percy Jackson and the Stolen Chariot when Percy asks Clarisse which of her brothers played a prank on her. He may have been the one that Percy awoke from a midday nap in The Titan's Curse.
- Michael Yew - A son of Apollo. He is the leader of the Apollo Cabin after Lee Fletcher died in The Battle of the Labyrinth. He is described as very short, four foot six, with personality that makes up for his height, and a face that reminds Percy of a ferret. In The Demigod Files, in an interview with Clarisse, she mentions that she would want to pulverize Micheal, thus stating that they are enemies. Percy finds it very interesting that he's the counselor. He is supposedly killed leading a group of demigods in the fight against Kronos' army. Percy looked everywhere for him, but only found his bow. He is presumed deceased, although this was never confirmed.
- Miranda Gardiner - Miranda is a daughter of Demeter who first appears in The Lost Hero and is the counselor of her cabin. Miranda had her nose (temporarily) removed by Lou Ellen, a daughter of Hecate.

- Silena Beauregard - A daughter of Aphrodite and the head of Cabin 10. Percy regards her as one of the nicer girls of the cabin and acknowledges that she is pretty, but still finds her to be a "neat freak". She participates in the Battle of the Labyrinth. She does not think that she is a good fighter and feels that she does not do anyone any good at camp. She unveils her hatred towards the hunters of Artemis, who say that love is worthless, to which she responds by stating that she is going to "pulverize" them. Silena is killed by a drakon when she fights it while pretending to be Clarisse in The Last Olympian. It is also revealed in The Last Olympian that she was the spy giving Kronos information about what was going on at Camp Half-Blood. When the Stoll brothers ask Percy about it, he will not let Silena be remembered as a spy. She did, however, want to stop being the spy when her boyfriend Charles Beckendorf died (charming her with his looks, Luke had promised that fewer lives would be lost and that Charles would be safe), but was blackmailed by Luke when he threatened to reveal her betrayal. This causes Silena to become even weaker or as Percy described, "She looked like glass. Like she was going to break at any time." Percy also notes that no one says the word "spy" during the burning of her shroud (which was hot pink with an electric spear embroidered on it).
- Sherman - A son of Ares. He, like Mark (another son of Ares), is mentioned by Percy in The Demigod Files in the short story Percy Jackson and the Stolen Chariot, when Percy asks Clarisse which of her brothers played a prank on her.

- Travis Stoll - One of the children of Hermes. He and his brother become the new counselors of cabin 11 after Luke went to Kronos. Travis is the older brother of Connor Stoll. Both are known to be crafty and mischievous. Percy finds it ironic that their last name is Stoll, like the word 'stole'. His and his brother's shenanigans incapacitated a member of Artemis's Huntresses, which enabled Percy to join the quest of The Titan's Curse. He and his brother have a larger role in The Last Olympian and both survive.
- Will Solace - He is a son of Apollo whom Percy took to heal Annabeth in The Last Olympian and become the leader of the Apollo Cabin as seen in The Lost Hero.
Mythological Characters[change | change source]
Some of the known characters of Greek Mythology have made an appearance in this series:
- Achilles - The image of Achilles appears briefly in The Last Olympian, warning Percy about The Curse of Achilles.
- Ariadne - Ariadne once helped Theseus when it came to him slaying the Minotaur. When Theseus unknowingly left Ariadne on an island, she was found by Dionysus who took her on as his wife. Theseus "abandoning" Ariadne was one of the reasons why Dionysus dislikes heroes. Ariadne made an appearance at the end of "The Titan's Curse" where she was walking arm to arm with Dionysus.
- Circe - Circe ran a magical beauty boutique in the Sea of Monsters. She was glamorous and went by the alias of C.C. While she treated females at her spa, she turned males into guinea pigs.

Not knowing which one is Percy, Annabeth fed them all multivitamins restoring Circe's victims to normal.
- Daedalus - Inventor of the Labyrinth, son of Athena, and father of Icarus. Daedalus killed his nephew Perdix and took his notes, which he then used to cast his animus (soul) into automatons after Athena branded him with the murderer's brand.

He later decides that it is time to go to the Underworld and leaves Annabeth his laptop which is filled with his notes and ideas. Nico unleashes Daedalus' spirit which destroys the labyrinth. When in the Underworld, King Minos tried to convince the other judges to punish him and fails. Daedalus' spirit now works as the Underworld's architect while being able to visit Icarus and Perdix on weekends.
- The Fates - The three women who control the threads of life.
- Clotho - The Fate who spins the Thread of Life.

- Atropos - The Fate who cuts the Thread of Life.
- Gaea - The embodiment of Earth, the mother of the Titans, Giants, and Antaeus, and grandmother of the Olympian Gods. She serves as the primary antagonist of The Heroes of Olympus series.

King Lycaon escaped when the Hunters of Artemis stopped him.
- King Midas - King Midas was a king who had the Golden Touch. He was referenced in "The Battle of the Labyrinth" where he states that Rachel's gold appearance made her look like she was touched by King Midas. In "The Lost Hero" King Midas was among the dead people brought back to life when the Doors of Death opened in Omaha, Nebraska. When Jason, Piper, and Leo arrived at Midas' mansion, he was polite. Midas told them that it was a silly story that he learned his lesson when he touched his daughter, turning her into solid gold. Midas touched Piper's backpack, turning it into flexible gold and making it magic, proving he still had the magic touch. Midas admitted that he had sometimes pat his son Lityerses on the pack accidentally, but he always had the lake to rinse it off. Midas finally revealed he was working for the Giants and turned Leo and Piper into gold. He gave Jason a choice: turn into a nice gold statue for his collection or fight Lityerses and die. Jason fought Lityerses and Midas. Midas and his son fought off the Hunters of Artemis before Jason managed to defeat Lityerses and unfreeze Piper and Leo.
- King Minos - King Minos is a former king who is one of the Judges of the Underworld. Nico summons in book four where he pretends to advise him on how to bring Bianca back from the dead he is when really trying to bring himself back. He is also seen as a live king in Percy's dreams/flashbacks. Near the end of the book, it is revealed that he is serving his own dark purpose when he kidnaps Nico and tries to kill Deadalus and use his knowledge. When Daedalus ends up in the Underworld following his sacrifice, King Minos tried to convince the other two judges to punish him and fails.
- King Sisyphus - A former ruler of Corinth. He had committed violations of guest hospitality, seduced his niece, plotted to kill his brother Salmoneus, and told the River God Asopus where Zeus had his daughter. His major crimes involved cheating death twice. The first where he tricked Thanatos into showing him how the chains worked causing Thanatos to be trapped until Ares freed him (Thanatos being trapped displeased Ares since no one in battle could die). The second time was when he complained to Persephone that his wife Merope did not give him a proper funeral and sent Sisyphus' spirit to the living. Even when Sisyphus did not want to return to the Underworld, he was forcefully dragged back there by Hermes. His punishment in The Fields of Punishment was to roll a boulder up a hill, and whenever he failed he would be tempted to try again. He appears in The Demigod Files in the story titled The Sword of Hades when Percy and Nico ask him advice while Thalia rolls the boulder up the hill. He does not really help them much, but he does say that he helped someone else. He said that he told that other person to go see Melinoe. Therefore, Percy and his friends go to see Melinoe as Sisyphus begs for them to set him free from his punishment as being here was a minor set-back.
- King Tantalus - Tantalus is a king from the Fields of Punishment who is the son of Zeus. He ended up there after killing his son Pelops, cutting him up, and serving him as food to the Gods. His punishment in the Fields of Punishment was to stand under a fruit tree in the middle of a lake where the branches and water would go out of reach from him. He becomes the activities director at Camp Half-Blood after Chiron is fired. He appears in The Sea of Monsters as a minor character. Even when hired as the activities director, he could not eat or drink as the food kept evading him. He is shown to hate Percy and his friends even more than he hates most half-bloods, yet shows favoritism to Clarisse such as naming her hero when the camp was attacked by Colchis Bulls or when she wins the chariot race. He throws a banquet in her honor. When the camp is attacked by a large flock of Stymphalian birds, Tantalus blames it on Percy, Annabeth, and Tyson's "bad chariot driving" despite that they were the ones who defeated the birds. When Tyson is brought to camp, Tantalus insults and makes fun of him even when Tyson is claimed by Poseidon. When at the end of the book, his curse is lifted by Dionysus just before he is sent back to the Underworld as he attempts to take some food along. Though none of the campers were sad to see him go.
- Lityerses - Lityerses is the son of King Midas. In "The Lost Hero," he appeared alongside his father.
- Medea - A sorceress and granddaughter of Helios that Jason, Piper, and Leo encountered in "The Lost Hero." She is shown as the head of a mall in Chicago that Jason, Piper, and Leo visit. She begins to show the demigods her stock of magic objects and potions, but becomes angry when she hears Jason's name (as he is named after the hero that betrayed her). It quickly becomes evident to Piper that Medea is an agent of Gaia, and the one who Hera had warned them about. Jason and Leo however are entranced by the magic in Medea's voice who tells them to attack and kill one another. Piper managed to bring the two to their senses and they blew up the mall. Medea shouts that she will not be abandoned again causing the three to quickly leave before she makes another attempt to destroy them.
- Oracle of Delphi - Apollo's Oracle of Delphi used to reside in the mummified remains of its host until its power was transferred to Rachel Elizabeth Dare in The Last Olympian. The Oracle's power originally passed from the deceased oracle to a newly chosen oracle; however, at the end of the second world war, the oracle gave a Great Prophecy predicting a child of the Big Three (Zeus, Poseidon, and Hades) would determine whether or not the gods would be preserved or destroyed. Using this information, the Big Three entered a pact in which none could continue to sire heroes. Before this, Hades bore two young children, Nico di Angelo and Bianca di Angelo. Zeus, fearing that either were the children of the prophecy, destroyed the hotel where the di Angelos lived with his master bolt, killing Maria di Angelo, Hades' lover. In revenge, Hades cursed the Oracle to ensure that the power of the Oracle of Delphi would not pass on to somebody else in hopes that it would soon return to the dust along with its prison. After the Battle of Manhattan in which Hades and Nico successfully assist in the defense of Mount Olympus, Zeus honors the Lord of the Dead. In response to his newfound respect from the other gods, he lifts the curse, allowing the Oracle's power to pass on into Rachel Elizabeth Dare, the last Oracle.

- Gabriel "Gabe" Ugliano - Known as "Smelly Gabe," he was Percy's stepfather. In appearance, he is heavy and bald, wearing thrift store clothes often. He managed the Electronics Mega-Mart in Queens as an occupation. As Percy described him in The Lightning Thief, he "was nice the first thirty seconds we knew him, then showed his true colors as a world-class jerk." During summer break from school, Gabe asks him for money for beer and for his poker games with his friends. Supposedly he can easily guess how much money a person has. It is implied that, at least once, he hit Percy's mother. Grover later tells Percy that Sally (Percy's mother) married Gabe to protect Percy from monsters who would have tracked him down otherwise. He smelled so "repulsively human" that his smell hid Percy's demigod scent from monsters. If she had not married him, monsters would have found Percy sooner. At the end of Book 1, he is turned to stone by Percy's mother (using Medusa's severed head) and sold as a statue, "The Poker Player", earning lots of money in the process.
- May Castellan - Luke's mother who attempted to become the Oracle. Since Hades's power prevented her from taking it, she was driven crazy and instead received small glimpses of her son's terrible future.

It was shown that she had numerous clippings of Hermes from advertisements and many beanbag monsters sitting in the house and on the front lawn.

When Percy, Nico, and Mrs. O'Leary come unexpectedly into Sally's apartment, Paul fully believes, and thinks it's "awesome!". Paul turns out to be an excellent swordsman due to the fact that he was a Shakespearian actor in college and assists in the fight to save Olympus in The Last Olympian. He asks Percy for permission before proposing to Percy's mother.
- Preacher - A preacher who raised money supposedly for orphans and spent it instead on his mansion until he was caught by the police.

After mistaking her for a monster and realizing she is human, Percy discovers that she can see through the mist. She leads the skeletons away from Percy. Rachel goes to the same school as Percy in "The Battle of the Labyrinth," realizing that the cheerleaders are actually empousai. In The Battle of the Labyrinth, she aids Annabeth and Percy by guiding them through the labyrinth to Daedalus's workshop. From there she, Percy, Annabeth, and Nico escape, only to enter again to locate Grover and Tyson. She is present at the deathbed of Lord Pan and, like the others, takes part of his essence within her. By throwing her hairbrush at Kronos, she provided enough of a distraction for Percy to escape the Titan Lord's time manipulation. It is hinted throughout the series that she harbors romantic feelings for Percy. In The Last Olympian, she begins having strange visions and becomes the new Oracle of Delphi after Hades's curse is lifted, under the guidance of Chiron and Apollo. Her first act as the Oracle is to deliver the Great Prophecy of the next generation of heroes.
- Sally Jackson - The daughter of Jim and Laura Jackson. She is the mother of Percy and she was married to "Smelly" Gabe." She then turned him to stone with the head of Medusa, and married Paul Blofis in the fifth book. In the beginning of the series, it is indicated that Sally works at a candy shop called "Sweet on America" and said that she wanted to be an author when she was young. In the third book, Percy guesses that Sally can see through the Mist and he believes that this was probably the reason Poseidon took interest in her. In the first book, she was thought to be killed by the Minotaur. Later on, it was discovered that she survived and that she was still alive in the clutches of Hades. She was freed once Percy gave the Helm of Darkness (which was also stolen by Luke) to the Furies.
- William Dare - He is Rachel Elizabeth Dare's father, who first appears in The Last Olympian. He owns a land developing company and is very wealthy. His family lives in a mansion in Brooklyn, where Rachel lives on the top floor. Rachel hates her father because of his job, but he seems to care about her. He said that he and her mother had really been looking forward to the vacation, but, according to Rachel, they both hate the beach, and are just too stubborn to admit it. He supported Rachel's going to finishing school. He walked into Rachel's room in Percy's dream, wearing pajamas with "WD" monogrammed on the pocket.
