List of Characters in The Percy Jackson and The Olympians Series and In The Heroes of Olympus Series - Olympian Gods

Olympian Gods

• Zeus/Jupiter: The king of the gods, lord of the sky, and god of lightning. Zeus is brother to Poseidon and Hades, uncle to Percy, Nico, and Bianca, father of Thalia, and son of Kronos. Jupiter is brother to Pluto and Neptune, father to Jason, and uncle to Hazel. His symbol of power is his Master Bolt. He is prominent in The Lightning Thief, but has only small roles in the rest of Percy Jackson & the Olympians. In The Lost Hero, under the influence of Khione, Zeus forbids contact between gods and mortals and closes down Olympus, although he indirectly aids the demigods several times on their quest, such as answering his son's prayer for aid against Enceladus. In the film adaptation, Zeus is played by Sean Bean.

• Hera/Juno: The queen of the gods and goddess of marriage. Hera plays a small role in The Titan's Curse, but helps Percy and the others on their quest in The Battle of the Labyrinth. 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. She frequently meddles in the affairs of demigods, however. As Juno in The Lost Hero, she is kidnapped by Gaia, and she contacts Jason Grace to rescue her. Previously, as Juno, she had sneaked out of Olympus and exchanged Percy and Jason to try to unite the Roman and Greek demigods, going against the wishes of Zeus in doing so. Compared to Hera, Juno is more rebellious; she states that Hera would not have disobeyed Zeus as she did. In the film adaptation, Hera is played by Erica Cerra.

• Achelous: A river god with the face of a man and the head of a bull. He had previously fought with Hercules where Hercules removed one of Achelous' horns. In The Mark of Athena, Hercules sends Jason Grace and Piper McLean to obtain Achelous's other horn. When Achelous was unwilling to give up his other horn to Hercules, Piper cuts off his other horn yet doesn't give it to Hercules. Piper uses his horn as a cornucopia at Hercules, and food comes pouring out of the mouth of the horn, burying Hercules. They fly away from Hercules's, island leaving behind a mourning Achelous and an angry Hercules.

• Aeolus: The custodian of the four winds. Aeolus is an unseen character in the Percy Jackson & the Olympians series. In The Last Olympian, he manipulates the winds to form a barrier around Olympus that protects it from air attacks from the Titans. This also impedes Pegasus traffic, however. In The Lost Hero, he has gone insane attempting to fill all the requests of the gods and wants to be recognized as a major god.

• Amphitrite: The queen of the seas. Amphitrite is the wife of Poseidon and a daughter of Oceanus. She is resentful of Percy, a living testament to her husband's unfaithfulness. She is described as a beautiful goddess, with black hair and small horns like crab claws.

• Aphrodite/Venus: The goddess of love, beauty, and lust. Aphrodite first appears briefly in The Titan's Curse. When Percy meets her, her appearance shifts constantly, matching every girl he has ever had a crush on (including Annabeth). Aphrodite is also the last child of Ouranos. Most of Aphrodite's demigod offspring are female, such as Silena Beauregard and Piper McLean. The latter's tomboyish habits vex Aphrodite, who twice changes Piper's appearance to make her look more beautiful. In The Mark of Athena, Aphrodite and Venus are revealed to be almost identical in personality and portfolio (the only difference is that Venus is more interested in high society functions), so the goddess is not rocked by an identity crisis like the rest of the Olympians. In the film adaptation, Aphrodite is played by Serinda Swan.

• Apollo: The god of the sun, light, poetry, healing, truth, plague, prophecy, music, the arts, the Oracle, and more. It is said that Zeus gave Apollo more powers than any other god because he is responsible. Apollo drives a flying red Maserati Spyder convertible that glows brightly like the sun. He appears to be about 18 or 19 years old, with sandy-colored hair, sky-blue eyes, and dazzling white teeth. Apollo seems flirtatious, playful, and optimistic, but he can also be one of the most dangerous gods when he wants to be. He also has the most children out of any other male god. Apollo wears Ray-Ban sunglasses and sports an iPod. Percy notes that he looks similar to Luke, but less evil and without a scar. Apollo is also described by Thalia Grace as being "hot". Like most other gods, Apollo is arrogant and has a big ego, and he is described as a very annoying brother by his sister Artemis. Apollo helps Percy and his friends by flying them to Camp Half-Blood in The Titan's Curse. Apollo also mentioned that Helios and Selene faded away when the Romans didn't build their temples. In The Last Olympian, he heals Annabeth's broken arm after she was thrown into her mother's throne. At the end of the war between the Titans and the gods, he certifies Rachel Dare as the new Oracle. His Greek and Roman forms have the same name, as he claims that "perfection can't be improved". In the film adaptation, Apollo is played by Dimitri Lekkos.

• Ares/Mars: The god of war and bloodlust. Percy first encounters Ares in The Lightning Thief, in which he drives a large black Harley-Davidson motorcycle with flame decals and a leather seat made from human skin. He wears red wraparound sunglasses that cover his flaming eyes, a bulletproof vest, combat boots, black leather biker clothes, and a black leather duster. He is the father of Clarisse, whom he blesses in battle in The Last Olympian. He appears as Mars in The Son of Neptune after a war game in Camp Jupiter, announcing the capture of Thanatos. He then claims Frank as his son, commissioning him to lead a quest to Alaska to free Thanatos. Mars is much more forward-thinking and strategic than Ares. In the film adaptation, Ares is played by Ray Winstone.

• Artemis/Diana: The goddess of the moon, wild animals, and the hunt. Artemis is the twin sister of Apollo. Cabin 8 at Camp Half-Blood is dedicated to her, though as she is a virgin goddess without demigod children, it is unoccupied, except for the rare visits when her Hunters visit. Artemis appears to be about 12 years old, with auburn hair and silver-yellow eyes, the color of the full moon. Artemis leads the Hunters of Artemis, a group of girls who pledge to give up love in exchange for immortality and agelessness. In The Titan's Curse, she is captured by Atlas, who forces her to hold up the sky for him. She is rescued by Percy, who holds the sky for her while she fights Atlas. Together, Artemis and Percy trick Atlas into taking back the sky. Thalia then joins her Hunters, preventing Thalia from fulfilling the Oracle's prophecy. Satyrs are also reported to be attracted to Artemis because she is "so into nature." In the film adaptation, Artemis is played by Ona Grauer.

• Athena/Minerva: The goddess of wisdom and battle strategy. Athena first appears in The Titan's Curse, where she dislikes Percy and his relationship with her daughter. Athena is beautiful, but serious and foreboding. Like most of her demigod children, she has grey eyes. She has been alternately described as having black and blonde hair. She does not actually give birth to her children; rather, they are conceived and born in her mind, just as she herself sprang from the mind of Zeus; a child of Athena is a literal brainchild. Athena considers Percy dangerous, given his potential to fulfil the prophecy that could destroy Olympus. Percy considers her the most dangerous Olympian because of her calculating intelligence, which ensures that her plans rarely fail. Her Roman form, Minerva, is much less imposing, being simply a virgin goddess of wisdom, and since the Romans take virginity quite seriously, Minerva has no children. The massive differences between Athena and Minerva render the goddess functionally insane during conflicts between the Greek and Roman demigods. Athena has a personal vendetta against Rome and Roman demigods ever since the Romans stole the Athena Parthenos statue from Athens during their original invasion of Greece, and over the centuries has sent many of her children on suicide missions to retrieve it. In the film adaptation, Athena is played by Melina Kanakaredes.

• Boreas/Aquilon: The god of the North Wind. Jason, Piper, and Leo seek Boreas in his palace in The Lost Hero. Jason, Piper, and Leo meet him in his palace when they come to him for help. He has two immortal children who were Argonauts, and is the father of Khione.

• Deimos: The god of terror. A son of Ares, Deimos only appears in the "Percy Jackson and the Stolen Chariot" story in The Demigod Files, where he torments Clarisse, a demigod daughter of Ares; Percy and Clarisse cooperate to defeat him.

• Delphin: The god of dolphins. Delphin is one of Poseidon's lieutenants in the war against Oceanus.

• Demeter/Ceres: The goddess of the harvest and agriculture. Demeter made few appearances in the Percy Jackson & the Olympians series. She and her daughter Persephone appear in The Last Olympian, where they participate in the battle against the Titans. Bacchus implies that the war between the Greek and Roman demigods has trapped her in her Roman form. In the film adaptation, Demeter is played by Stefanie von Pfetten.

• Dionysus/Bacchus: The god of wine and madness. Dionysus is Percy's cousin and the father of Castor and Pollux. He is the director of Camp Half-Blood, a position given to him as a punishment by his father Zeus for chasing an off-limits nymph. At camp, he is known as "Mr. D." Dionysus hates his job and has a low opinion of demigods because of Theseus's abandonment of Ariadne (whom Dionysus made into his wife) and how Jason abandoned Medea. Although he enjoys playing with the camp satyrs. In The Battle of the Labyrinth, he goes in search of minor gods to recruit against the Titans. Although he claims Percy "always manages to annoy him," he has saved the lives of Percy and his friends on several occasions. When war breaks out between the Greek and Roman demigods, Dionysus goes through an identity crisis, but is able to focus enough to force himself to remain in his Bacchus form. In the film adaptations, Dionysus is played by Luke Camilleri in the first film and by Stanley Tucci in the second film.

• East River: A river god who personifies the river in New York. East River only appears in The Last Olympian, where he sinks Titan ships coming to attack Olympus. He is a rival of Hudson River.

• Ganymede: The gods' cup-bearer. In The Sea of Monsters, Ganymede's voice was heard advising users of the Gray Sisters' taxi service to use the "seat belt" (a black chain).

• Hades/Pluto: God of the underworld, riches, and death. Although technically not an Olympian, Hades is still considered to be one of the most powerful gods as he is one of the original six gods to be born of Kronos and Rhea. He is the middle brother of Poseidon and Zeus, father of Nico, Bianca, and Hazel, uncle to Percy, Jason, and Thalia, and son of Kronos and Rhea. He is the husband of his niece Persephone. Hades is portrayed as cunning and resentful of the Olympians proper, though not specifically hostile to them. In The Last Olympian, he traps Percy, planning to hold him in an underworld prison so Nico can fulfill the great prophecy. Nico, however, helps convince Hades to join in defense of Olympus against Kronos and the Titans. After his army of the dead helps Olympus win, the Olympians reward him, his demigod children, and the minor gods with full recognition at Camp Half-Blood. In the film adaptation, Hades is played by Steve Coogan and is depicted as also having a fiery winged demon form.

• Hebe: The goddess of youth, daughter of Zeus and Hera. Hebe is among the minor gods who allied themselves with the Titans in the Percy Jackson & the Olympians series, dissatisfied with Olympian rule. She was granted cabin 18 for her children after the war. Hebe is married to Hercules.

• Hecate: The goddess of magic, cousin of Apollo and Artemis. Hecate is an ally of Kronos in the Percy Jackson & the Olympians series. Her empousai minions and her daughter Circe torment Percy in The Battle of the Labyrinth and The Sea of Monsters, respectively. After the Titans are defeated, she reconciles with Olympus and is granted cabin 14 at Camp Half-Blood.

• Hephaestus/Vulcan: The gods' blacksmith and the god of fire. Father of Charles Beckendorf and Leo, Hephaestus acts as a major ally of Percy in The Battle of the Labyrinth. In The Lost Hero, he defies Zeus by speaking to Leo, to whom he delivers the head of Festus to be used as the figurehead for the Argo II, a war vessel for the gods to use against Gaia's forces. In the film adaptation, Hephaestus is played by Conrad Coates.

• Heracles/Hercules: The greatest and strongest hero in Greek mythology who is the son of Zeus. Heracles was mentioned a lot in the Camp Half-Blood franchise. In The Titan's Curse, Zoë Nightshade was the one who gave Heracles the ideas for several of his labors, including how to steal the Apples of the Hesperides. Percy was not pleased that Heracles never gave Zoë any of the credit for this. In The Demigod Diaries episode "Percy Jackson and the Staff of Hermes," Hercules was mentioned by Cacus, who stated that Hercules was the only one to have defeated him. Hercules appears as a god in The Mark of Athena. He is tasked by Zeus to guard the Pillars of Hercules. Hercules is willing to let the demigods pass into the Mediterranean Sea at first. But when Jason and Piper mentioned that they were ordered by Hera to stop the Giants, he becomes uncooperative and orders them to break the remaining horn of the god Achelous. They do so, but Piper refuses to give the horn to Hercules, which enrages him. Yet the demigods manage to escape his wrath when Piper uses the Horn of Achelous to bury Hercules in food. They fly away from Hercules's island, leaving behind a mourning Achelous and an angry Hercules.

• Hermes/Mercury: The god of travelers, communication, and thieves, and the messenger of the gods. In the Percy Jackson & the Olympians series, Hermes helps Percy, hoping that he will be able to redeem Luke. After Luke's death in The Last Olympian, he becomes angry at Annabeth for not saving him when she had the chance. In the film adaptations, Hermes is played by Dylan Neal in the first film and by Nathan Fillion in the second film.

• Hestia/Vesta: The goddess of hearth and home. Hestia makes few appearances, but exemplifies quiet power when she becomes involved in the affairs of demigods and Olympians. Originally an Olympian, she sacrificed her place on Olympus to Dionysus/Bacchus in order to prevent a civil war. She is the title character of The Last Olympian, wherein she aids Percy in his fight against Kronos.

• Hudson River: A river god who personifies the river in New York. Hudson River only appears in The Last Olympian, where he sinks Titan ships coming to attack Olympus. He is a rival of East River.

There she sends the demigods to Phineus to discern the location of Thanatos. Her cabin at Camp Half-Blood is cabin 14.

• Janus: The god of gates, doorways, beginnings, and endings. He appears as a minor character in The Battle of the Labyrinth, where he offers Annabeth a choice between two doors, which represents the situation she was in when she had to make the decision about saving Luke's soul. He has two faces, and each face seems to think the exact opposite of what the other face thinks. He is also mentioned when Percy Jackson has a dream of Daedalus. Janus makes him choose to become a murderer, which he must bear as a burden for as long as he lives.

• Khione: The goddess of winter and daughter of Boreas. She appears in The Lost Hero. Jason, Piper, and Leo encounter her in Boreas' palace. She ends up betraying them to help Gaia in her conquest.

• Persephone: The goddess of spring and queen of the underworld. Persephone is the wife of Hades, and the daughter of Demeter and Zeus. Hades only allows her to visit Demeter, her mother, in the spring and summer; during these seasons, Persephone is kinder and more beautiful. Unlike most minor gods, she sides with Olympus during the war against the Titans. Persephone appears in The Demigod Files and The Last Olympian. In the film adaptation, Persephone is played by Rosario Dawson.

• Phobos: The god of fear. A son of Ares, Phobos only appears in the "Percy Jackson and the Stolen Chariot" story in The Demigod Files, where he torments Clarisse, a demigod daughter of Ares. He has the power to show people their greatest fears, but Percy and Clarisse cooperate to defeat him.

He remains there in The Last Olympian while the other Olympians fight Typhon, until Percy convinces him that his power is necessary to defeat Typhon. In the film adaptation, Poseidon is played by Kevin McKidd.
