First Cohort
Octavian
"Surrender to Rome!"
Octavian is a legacy of Apollo, meaning he is descended from one of Apollo's demigod children. This gives him the gift of prophecy and a position at Camp Jupiter as its augur, who kills animals and interprets their innards to see the future. Due to this being set in the modern world and the impracticalities of gutting animals every time the future needs to be read, Octavian guts stuffed animals instead.
He is extremely ambitious and power-hungry, and aims to rise to the rank of praetor. He's willing to get his hands dirty in order to accomplish this, as seen when it's hinted he murdered Gwen. He also possesses a burning hatred of all Greeks, and calls for war against them. Reyna sees him as a danger to the camp, but as her nominal Number Two he finds ways to circumvent this.
- Accidental Suicide: Attempts use onagers to destroy Gaia and Camp Half-Blood without having to do any work, while failing to notice that his toga got snagged on the ammunition he's about to fire. This results in him being sent flying towards Gaia and dying with her in a fiery explosion.
- Ambiguously Evil: Well-Intentioned Extremist or power hungry Corrupt Politician? It is not helped that he eventually starts to crack, throwing mental problems into the mix.
- Ambition Is Evil: Dead set on becoming praetor so he can order a quest to find the Sibylline Books.
- Asshole Victim: Due to being a complete jerk with practically no redeeming qualities, a lot of people, Greek and Roman, in-universe and out, did not feel sorry for him when he got himself launched by a flaming catapult and died. Not even his most loyal bodyguard bothered to warn him that his toga was snagged.
- Big Bad Ensemble: His desire to destroy the Greeks makes him a constant secondary antagonist throughout the series.
- Big Bad Wannabe: At the end of the day, Octavian is merely a deluded pawn used by Gaia to sow conflict between the demigods.
- Blackmail: In The Son of Neptune, he's pretty clearly blackmailing Hazel into getting whatever he wants from her.
- Commander Contrarian: He disagrees with every decision Reyna makes.
- Corrupt Politician: He manages to win favor in the council by backstabbing everyone else.
- Creepy Blue Eyes: He's got dark blue eyes that compliment his generally creepy appearance.
- Dirty Coward: Best exemplified in The Blood of Olympus, in which he intends to destroy Camp Half-Blood using onagers without actually having to do any work himself and still being able to claim the glory for it. He also runs away once Gaia reveals herself after her awakening.
- Evil Chancellor: Seems to be acting as one to Reyna, as an active advocate of war against the Greeks. She quickly puts a stop to that. The moment she turns her back, he announces that they're changing their plans.
- Evil Counterpart:
- To Rachel. He serves the same oracular purpose as she does, but he's creepy and manipulative while she's straightforward and nice. They meet in the fourth book; it doesn't go over very well.
- He's also this to Will Solace, both are descended from Apollo, but while Will who is more of a medic than a seer wants to help make peace, Octavian wants to destroy the Greeks. Will explains that what Octavian was doing was not what Apollo would want.
- Fortune Teller: An augur, specifically, and using his insight into the future to twist Camp Jupiter politics to his advantage.
- General Ripper: He has this relationship towards the Greeks.
- Hate Sink: His jerkass behavior when he's first introduced and later acting purely on paranoia against the Greek camp and recruiting of monsters and sociopaths into his army in said paranoia make him this. Even his own bodyguard dislikes him.
- Hoist by His Own Petard: In the fifth book, he dies helping to destroy Gaea. He intended to hog all the glory of defeating her for himself, but instead his clothes snag on the ammunition of the onager he fires. He was able to do something useful for once.
- Identical Stranger: An amnesiac Percy notes he resembles someone he can't remember, but the reader can probably tell is Luke.
- Jerkass: His rampant hatred of Greeks, hunger for power, and cruelty towards others more than qualifies him for this.
- Jerk with a Heart of Jerk: Never once shows a redeeming feature.
- Manipulative Bastard: He uses his connections and cunning to try and take over the Legion for himself.
- Meaningful Name: Shares quite a few personality traits with the original Octavian, including ambition and being a smooth talker.
- Not-So-Well-Intentioned Extremist: Wants to go war with the Greeks allegedly to protect Camp Jupiter, but the fact that he goes behind Reyna's back to do so and recruits criminals and monsters proves that he just wants to seize power and eliminate people he hates.
- Number Two: The augur is right below the two praetors in the chain of command, unfortunately.
- Prophecies Rhyme All the Time: In a series that mostly plays this straight, Octavian lampshades it by demanding that the prophecy Mars gives be cryptic and vague. Mars pulls out a grenade in response.
- Prophecy Twist: A good chunk of his Sanity Slippage comes from his obsession with Apollo telling him that one day he would be remembered for saving Rome. He clearly didn't expect that would mean that he'd be remembered for getting his clothes stuck on an Onager, causing him to be hurled screaming to his death via contributing to the gigantic explosion that permanently dispersed Gaea.
- Sanity Slippage: Suffers from this to a serious degree in The Blood of Olympus when he essentially dives head first off the deep end and begins recruiting criminals and monsters to help his cause.
- Screw the Rules, I Have Connections!: Octavian comes from a very influential Roman family descended from Augustus himself. He uses this to further his own political ambitions.
- Seers: Guts teddy bears to see the future.
- The Sociopath: At one point, it's indicated that he stabbed Gwen In the Back after the War Games were over, and he shows no remorse for doing such a thing.
- Sore Loser: Heavily implied to have killed Gwen in retaliation for losing the war games.
- The Starscream: He's the traitorous second-in-command to Reyna.
- Trojan Horse: Invokes it when he advises the Romans to "beware of Greeks bearing gifts". Subverted, since that wasn't the plan to begin with.
- Undignified Death: In addition to the humiliating and terrifying way he died, the last person to see him alive was Leo, who didn't even notice he was there aside from the sound of someone screaming like a small girl.
- War Hawk: Is the most vocal in Camp Jupiter about going to war against the Greek demigods, and when Leo, possessed by an eidolon, starts firing on the camp, thereby giving him a reason, Octavian eagerly jumps on it and whips the Romans into a war frenzy.
Michael Kahale
A son of Venus and centurion of the First Cohort.
- Badass in Distress: He leads a team of commandos to attack Caligula's fleet, but is captured. Thankfully, Lavinia and the nature spirits save him before they destroy the ships.
- The Big Guy: He is very large, enough to crush rock with his bare hands.
- Charles Atlas Superpower: Being a son of Venus, none of his godly abilities augment his body. He got that strong through hard work.
- Commander Contrarian: He questions some of Octavian's decisions.
- Everyone Has Standards: As loyal as he is to Octavian, he's sickened by Octavian reinstating Bryce Lawrence as a probatio.
- The Ghost: He's mentioned several times in The Tyrant's Tomb but never appears (or at least is never singled out from the other Romans).
- Number Two: The second-in-command of Octavian.
- Punch-Clock Villain: He's a good guy, but he's very loyal to Octavian, who sponsored his entry into the legion. This loyalty however, has limits and reaches them during the final battle with Gaea.
- Shoot the Dog: Though he sees Octavian's robes are caught on the rope of the onager, he stands by and does nothing to warn the other teen or prevent Octavian from triggering it and causing his own death.
Second Cohort
Larry

Third Cohort
Hank
A centurion of the third cohort of unknown heritage.

- Green Thumb: As a daughter of Ceres.
Fifth Cohort
Dakota
Son of Bacchus, senior centurion of the Fifth Cohort.
- The Alcoholic: Well, not quite...Percy: You let him drink wine?
Hazel: Gods, no! That would be a disaster. He's addicted to red Kool-Aid. Drinks it with three times the normal sugar, and he's already ADHD — you know, attention deficit/hyperactive. One of these days, his head is going to explode. - Heel–Face Turn: He defies Octavian and tries to stop the Roman siege of Camp Half-Blood.
- History Repeats: Once again, the final battle at one of the camps in a series's fourth book results in the death of one of Dionysus/Bacchus's sons.
- Mauve Shirt: He's one of the more prominent minor characters at Camp Jupiter, and he dies in the climax of The Tyrant's Tomb.
- Trademark Favorite Food: Red Kool-Aid.
Gwendolyn
A legionnaire of unknown heritage and centurion of the Fifth Cohort.
- Benevolent Boss: She's quite nice to her subordinates.
- In the Back: She was impaled from behind with a pilum.
- Impaled with Extreme Prejudice: She's run through with a pilum during one of the war games.
- Not Quite Dead: Those tropes about her being impaled would have spelled the end for her, had Thanatos not been a bit tied up.
- The Pollyanna: She's described as being optimistic by her fellow legionnaires and is less fazed then you'd expect of someone who died and was resurrected.
- Screw This, I'm Outta Here: Not a combat example, but narrowly avoiding death caused her to step down as centurion and leave to attend college.
- Team Mom: She takes care of the Fifth Cohort and tries to keep their spirits up.
Lavinia Asimov
A daughter of Terpsichore, the Muse of dance, and one of Hazel's subordinates. She is promoted to Centurion after Hazel's ascension to Praetor.
- Attention Deficit... Ooh, Shiny!: She's even more hyperactive and anxious than most other demigods.
- BFG: Her manubalista is the crossbow equivalent, a huge weapon that is extremely powerful but very slow to reload.
- Bubblegum Popping: She regularly chews bubblegum to the extent that she carries 5 packs.
- Conscience Makes You Go Back: After needing to put down one of her zombified friends in Tarquin's tomb and finding out that Caligula and Commudus are bringing enough Greek fire to turn Camp Jupiter into another Pompeii, Lavinia briefly loses all hope and tries to hightail out of there with the nature spirits. Then they have a change of plans, storm the yachts, and rig the Greek fire cannons so that the entire fleet is completely annihilated.
- Informed Judaism: She often fiddles with a Star of David necklace when nervous and mentions her bat mitzvah, but unlike Samirah Al-Abbas, no attention is drawn to her religion and the oddness of someone from an Abrahamic faith being a Roman demigod.
- Interspecies Romance: Currently dating a dryad named Poison Oak.
- Outdoorsy Gal: She has a love of hiking and a natural camaraderie with the nature spirits of Camp Jupiter and its surroundings.
- Shoot the Dog: She is forced to shoot the zombified Bobby to save Hazel.
- The Sneaky Guy: She has a talent for getting in and out of places unseen. She most uses it to sneak away from patrol and meet up with cute dryads but it also comes in handy escaping Tarquin's forces after leading them away from Apollo, Hazel, and Meg.
- Spell My Name With An S: Her surname is spelt as 'Asimov' in canon, but would be spelt as 'Asimova' in reality due to Russian Naming Convention, which leads to confusion over how her surname should be spelt.
- Twofer Token Minority: She's a Jewish lesbian.
- Vitriolic Best Buds: She has this dynamic with Don the faun.

Former Legionnaires
Bryce Lawrence
A former member of the Twelfth Legion, expelled for his sociopathic tendencies. He is a descendant of Orcus, the god of broken vows and eternal punishment. He is reinstated by Octavian and dispatched to hunt down Reyna.
- Asshole Victim: Considering the pleasure and glee he took in torturing his victims, it's pretty cathartic when Nico lets loose on him.
- Ax-Crazy: Is pretty known for being a remorseless and bloodthirsty psychopath, having killed his centurion and even stating at one point that he considers the screaming in the Fields of Punishment to be music to his ears.
- The Brute: He's one of Octavian's "attack dogs".
- Dirty Coward: He's very smug when he has the upper hand; however, when Nico lets loose on him, he's reduced to begging for mercy.
- Dragged Off to Hell: Courtesy of Nico, who turns him into a ghost and sends him straight to the Fields of Punishment.
- Screw the Rules, I Have Connections!: He would have been executed for his crimes, but his family's influence let him off with exile.
- The Sociopath: Reyna essentially calls him one in describing his sheer remorselessness and bloodthirsty tendencies, not to mention his murder of his centurion, which was why he was expelled in the first place.
Michael Varus
The historical praetor who lost the legion's standard and a large reserve of weapons in a futile attempt to fulfill a prophecy meant for another. His tropes can be found here.

Julia
