The Heroes of Olympus/Characters

Everything About Fiction You Never Wanted to Know.


Characters who appear in The Heroes of Olympus.

The Seven

Jason Grace

Son of the lord of the sky and hero of the first book, who is amnesiac at the start of The Lost Hero.

Percy Jackson

Son of Poseidon. A lost hero.

"He'd perfected his wolf stare over the last few months - a look that said: However bad you think you are, I'm worse"

Piper McLean

Daughter of Aphrodite, one of the resident heroines and Jason's girlfriend (sort of, but not really).

Leo Valdez

Jason's mischievous best friend and a son of Hephaestus.

Frank Zhang

A resident of Camp Jupiter.


Hazel Levesque

A resident of Camp Jupiter.

  • All of the Other Reindeer: Got picked on a lot as a kid in New Orleans. Camp Jupiter wasn’t all that much better.
  • Back from the Dead: Spent 70+ years in the Fields of Asphodel after she sacrificed her place in Elysium to keep her mother out of the Fields of Punishment. Got out after Nico, after discovering that Bianca had already chosen to be reborn, rescues her instead.
  • Be Careful What You Wish For: Pulls up cursed riches due to mommy's request gone wrong.
  • The Big Easy
  • Blessed with Suck
  • Cool Horse: Is the only person the Cool Horse, Arion, will listen to (thanks in no small part to her gold-producing powers).
  • Dark and Troubled Past / Dark Secret: Was forced by Gaea to use her powers to reconstruct Alcyoneus in Alaska.
  • Dishing Out Dirt: Daughter of Pluto. Unlike Nico, she got the "god of wealth" half as opposed to the "god of death" half. Unfortunately, her power is mostly limited to precious gems and metals. It's also the curse her mother saddled her with.
  • Eyes of Gold: Justified. She’s the daughter of the god of wealth.
  • Fish Out of Temporal Water
  • Foreign Cuss Word: "As Hazel marched up the hill, she cursed in Latin. Percy didn't understand all of it, but he got son of a gorgon, power-hungry snake, and a few choice suggestions about where Octavian could stick his knife."
  • Heroic Sacrifice: Killed herself and her mother to stop Gaea from raising Alcyoneus and then gave up Elysium so her mother wouldn’t go to the Fields of Punishment.
  • Human Mom, Nonhuman Dad
  • It's All My Fault: Alcyoneus coming back to live was directly Hazel's doing. Even though she was forced to by Gaea, Hazel still feels hugely guilty.
  • Long-Lost Relative: To somebody we know well from Camp Half Blood. Seems to be a trend in this series. Turns out to be Nico.
  • Meaningful Name: Levensque means either somebody who served in the household of a bishop, or just bishop. Of ancient Greek origin, curiously.
  • Pensieve Flashback: Hazel has some pretty powerful "blackouts". Even manages to pull Frank into one.
  • Resurrected for a Job: Implied as much.
  • Older Than They Look: Mentally, anyway. Being a child of Pluto, she remembered everything during her 70+ years in the Fields of Asphodel.
  • Ragin Cajun: Lived in New Orleans until she was 13.
  • Replacement Goldfish: Technically being Nico's sister, she has shades of this for Bianca.
  • What Could Have Been: In-universe example. Had she stayed in New Orleans, Hazel would have grown up to marry her childhood friend, Sammy (Leo’s grandfather).

Other Demigods

Annabeth Chase

Heroine of the last series, she misses most of the book because she's looking for Percy Jackson. Daughter of Athena.


Thalia Grace

A daughter of Zeus, lieutenant of Artemis, leader of the Hunters.

Nico di Angelo

Son of Hades. Kidnapping bait.

Reyna

Jason's pre-amnesia love-interest and the other praetor of Camp Jupiter.

  • Braids of Action
  • Gondor Calls for Aid: Knowing that Camp Jupiter will soon be attacked, she tells Percy to find her sister Hylla and ask her to help.
  • Lady of War: Daughter of Bellona, the Roman goddess of war, specifically.
  • Meaningful Name: Her name, like the similar-sounding Spanish "Reina," is a derivation of the Latin "Regina" (queen, counsel).
  • Reasonable Authority Figure
  • Ruling Couple: Averted? She points out it might have happened with Jason if he stayed, then offers this to Percy.
  • The Woman Wearing the Queenly Mask: Has been carrying the leadership of Camp Jupiter on her own for the past eight months and is struggling under the weight of both protecting everybody from the monster attacks and fending off Octavian’s attempts at seizing the other praetorship.

Octavian

A descendent of Apollo and resident of Camp Jupiter who guts stuffed animals and uses their fluff to tell the future.

Will Solace

A son of Apollo.

Clovis

A son of Hypnos.

Butch

A son of Iris.

Drew Tanaka

A daughter of Aphrodite and also former head counselor of her cabin.

Hylla

Reyna's sister, and the Queen of the Amazons.

Gods and Giants

Boreas and Family

The North Wind and his kids.

Aeolus

King of the winds, weatherman of Olympus.

Aphrodite

Goddess of love and beauty, who plays a bigger role this time around.

  • Love God
  • Shipper on Deck: Even more than in the last series - she doesn't care to hide it for anything. Add Jason/Piper to her list of ships.

Aphrodite: Paris and Helen were a cute couple...

Hera/Juno

Queen of the Gods.

  • Babysitter From Hell/Magical Nanny: For Leo.
  • Character Development: Compared to how she was in the previous series, she's far nicer to demigods. She's shown Jason AND Percy respect and even been supportive, not even getting mad when Percy was basically chewing her out in his dreams. While Jason has some leeway as his Patron Saint, Percy has only the fact that he's one of the seven, and while she could try to boss him around, she's being pretty nice about everything. She extended Frank's life as well.
  • Gambit Roulette: She seems to be pulling this considering the whole Jason/Percy switch was her idea. Bonus points for working on this long before the first series, considering her actions with Frank and Leo.
  • I Have You Now, My Pretty
  • Patron Saint: For Jason. And of Rome in general.
  • Queen Incognito: Juno briefly pretends to be an old hippie lady dressed in trash bags when she dishes out her Sadistic Choice to Percy. She drops the act once they make it to Camp Jupiter.
  • Wicked Stepmother: Only inverted towards Jason.
    • Arguably this is becoming a bit of Character Development or or even Alternate Character Interpretation.
      • It could just be Fridge Brilliance. Why wouldn't Hera be nice to a demigod son of Zeus on the eve of the Gigantomachy? during the last one, Porphyrion nearly raped her until Hercules managed to kill him, which is what caused Hera to accept him in the first place. Maybe she just wants to be sure she'll be saved again.

Ares/Mars

The God of War. Father of Frank Zhang.

  • Blood Knight: Subverted as Mars. He’s not about endless bloodshed without resolution.
  • Character Development: Gets some on Son of Neptune.
    • Justified considering that Mars is held in much higher regards to the Romans than Ares to the Greeks (the Spartans are an execption).
  • Colonel Badass: Mars's preferred form.
  • Doting Parent: Compared to how Ares treated Clarisse, his Roman counterpart nearly rivals Poseidon.
  • Obfuscating Stupidity: Pretends to not remember who Percy is in front of the Romans even though Frank can tell he’s lying.
  • Pet the Dog: Keeps Grandmother Zhang company while she’s waiting for Frank to come home one last time.
  • Vitriolic Best Buds: Acts like this with Percy, who's probably a lot more appealing to Mars than he was to Ares.

Thanatos

The god of death.

Terminus

The Roman god of boundaries.

Gaea

The goddess of the Earth and progenitor of the Titans and, by extension, the Olympians. She's the main antagonist now.

Enceladus

Porphyrion

The most powerful of the giants and their king. Deigned to be a direct counter to Zeus including power.

Polybotes

  • Arch Enemy: To Poseidon
  • Informed Ability: Supposed to be the anti-Poseidon, and his mere presence left Percy in a shivering pile the first time he saw the giant. Percy proceeded to open up a can of whoopass on him when they encountered one another during the last battle, and Polybotes became the first giant to lose against a demigod in single combat (okay technically a god was there). Some anti-Poseidon.
    • It could be that what made Percy Freak-Out was not Polybotes, but the notion of evil Centaurs and Cyclops.
      • The book specifically states that looking at Polybotes made Percy feel the major nausea, though.
    • It's also possible that since he is the Anti-Poseidon that he was intending to fight him in the sea or ocean so that Poseidon would think he had the advantage, but since Polybotes' touch turns water to poison. that in a straight up fight he would have the advantage.
      • That is a possibility—but Percy was offered a choice in the beginning of the book: fight for the chance to save all that he loves, or retreat to the sea and live a long life, untouchable by the war and invincible in his own territory. That this decision mirrors one made by Hercules, and that it was given by a god, lends credence to it being an honest option for him, which suggests that Polybotes wouldn't have been able to kill him in the ocean either.
      • Like the old monsters That attack poseidon's domain in TLO, Hera might have meant for Percy to hide in the far reaches of the ocean while Polybotes usurped his father's kingdom.
  • Prongs of Poseidon: Simultaneously Type I and Type II.

Alcyoneus

Other Mythological Creatures

Gleeson Hedge

A Protector.

Trainer of Greek heroes.

Lupa

Trainer of Roman heroes.

Ella the Harpy

Tristan McLean

Piper's father, who works as a movie star.

  • Fake Nationality: He never plays a Native American in any movie he's in, despite being Cherokee.
  • Hostage Situation / I Have Your Wife: Gaia kidnaps him so that Piper will do what she wants. It doesn't work.
  • Hot Dad: All the girls in Piper's school have crushes on him. Justified as he's a movie star.
  • Mind Wipe: Piper gives him a drink that erases his memory of the whole ordeal, even if it helped the two of them grow closer.
  • Window Love: With Piper, after he loses his memory.
  • Weak-Willed: Somewhat. He can't handle the existence of the Mist, which Aphrodite cites as her reason for staying away.

Hazel's deceased mother.

Grandmother Zhang

Frank's grandmother, who was his guardian after his mother's death.

Emily Zhang

Frank's deceased mother, who died in the war against Afghanistan.

Esperanza Valdez

Leo's deceased mother. Are you starting to see a pattern here?

  • Deceased Parents Are the Best: When Leo's not angsting about killing her with his fire powers, he remembers her fondly.
  • Doting Parent: As much as she could, when she was alive.
  • Hot Mom
  • Meaningful Name: "Hope."
  • Spicy Latina: Averted. She was described as being very warm and friendly, as well as satisfied with her living conditions as long as she had Leo.
  • Wrench Wench: Very talented with machines, which, perhaps unsurprisingly, attracted the attention of Hephaestus.

Jane

Tristan McLean's secretary, and the one who minds Piper when he's busy.

Sammy

Hazel's almost-boyfriend from her time in New Orleans. His surname just happens to be Valdez, and it's implied that he's Leo's grandfather.
