Clayton HaggertyThe first antagonist of Demigod Power, Clayton was a son of Moros, Greek God of Doom, and a highly skilled combatant who fought during the American Civil War against the Romans, due to being tricked into believing the Romans had butchered his family, when in fact the children of Ares had done the killing themselves. When Clayton discovered the treachery, he attacked camp only to be struck down by Ares himself. Nemesis took pity on him and negotiated with Hades to release his soul 150 years later. This was intended to give him a second chance at life, but when Clayton awoke he was consumed by a desire for revenge, and vowed to take revenge on the Olympians by destrying camp and thus killing all their children. He is the great-great-great-great-great-grandfather of camper Jolon Edgecomb.
Tropes that apply to Clayton:
- Alas, Poor Villain: Despite what he attempted to do, he is buried among the heroes of Camp Half-Blood, in recognition of his first life and the injustices thrust upon him.
- All There in the Manual: His backstory makes much more sense if you've read The Lost Hero, which sheds light on the Demigod Civil War.
- Anti-Villain: Type II.
- Artifact of Doom: He uses one to increase his power so he can summon an army of Keres.
- Badass Beard: Also doubles as a Beard of Sorrow.
- Bad Powers, Good People: He originally started out as this in his first life, and continued until his first death. It's debatable whether or not he transitioned to Bad Powers, Bad People in his second life, because he was majorly motivated by justified revenge and not malicious intent.
- Bare-Fisted Monk: Extremely notable in a world where demigods require weapons made out of certain metals in order to kill monsters, Clayton's One-Hit Kill powers allowed him to use only his fists in battle.
- The Beastmaster: He could summon Keres (death-spirits) to do battle with him, and summons a whole army of them to attack camp.
- Berserk Button: Anything to do with his dead family or Ares, or Ares' children, would send him flying into a rage.
- Casting a Shadow: As he grew more powerful, he developed this ability.
- Crazy-Prepared: He showed shades of this before launching his attack on camp. It paid off, because by the time he actually stepped into the open and made his plan known, he was five steps ahead of camp and they were rushing to catch up with him.
- He recruited Ryder expressly to look for the artifact he needed, and to spy on camp for him, so he would know exactly where it would be when he entered camp.
- He also had a captured demigod ready and waiting for interrogation/execution to prove his worth to Cal and Lykaina when attempting to ally with them.
- He kept Jace with the group of demigods pursuing him so he could stall them if they started to catch up.
- Death Seeker: Implied by his conversations with Jace and his reaction upon seeing Tessa.
- Disc-One Final Boss: More apparent in hindsight after the Ronin War, but Clayton was the least powerful of all the main antagonists, and he was defeated rather soundly during his final battle. However, his attack on camp managed to weaken it enough thst the Ronins were able to invade and cause a LOT more devastation.
- Don't Make Me Destroy You: Is on the receiving end of this from Jolon, and offered a chance to walk away. He refuses and attacks, forcing Jolon to kill him.
- Fiction500: States that his family has become incredibly wealthy in the modern era. This is supported when it's revealed that Jolon, who is incredibly rich, is a descendent of his.
- Good Is Not Soft: Even back when he was firmly a good guy, before the war, Clayton was a renowned warrior who did not shy away from conflict.
- Hope Spot: When he sees his reincarnated wife Tessa, and recognizes her, it briefly looks like he might surrender his forces. However, he only grows angrier and blames the gods for taking her away from him even in death, because she won't be in the Underworld anymore.
- Idiot Ball: For all his Crazy-Prepared planning, he chose to drop a temple on the demigods pursuing him and leave them for dead, rather than kill them himself to make sure they wouldn't follow.
- Karmic Death: He rose to avenge his dead family, and was killed by a descendent of his, who had inherited the very same Touch of Death power that made Clayton infamous.
- Long Dead Badass: Even before his debut, Clayton was mentioned offhandedly once or twice by other characters, and usually his skill in combat was addressed.
- Luckily, My Shield Will Protect Me: He has a gauntlet on his left hand that doubles as a collapsible shield.
- Power Glows: Activating his Touch of Death power made bright red light burst from the eyes andout of his victims.
- Red Eyes, Take Warning
- Roaring Rampage of Revenge: His entire plan is this.
- Touch of Death: His signature ability, allowing him to instantly kill anyone he could get his hands on.
- Tragic Villain
- Used to Be a Sweet Kid: It is outright stated that Clayton was a nonviolent and a downright pacifist in his first life. His refusal to take part in the war between Greeks and Romans is what made the Greeks decide to frame the Romans for the murder of his family, because they were losing and had no other option left. When he is seen again in the Underworld after his second death, he shows shades of this.
- Villain's Dying Grace: Subverted. In his final appearance Clayton is already dead, and appears as a ghost being escorted into the Underworld by Charon. However, his last act is to shove Charon into the River Styx, allowing Taren and Hunter to escape the Underworld. When asked why he would help them, Clayton replies that life is too fleeting to waste it on anger and pain, something he never learned while he was alive.
- Volcanic Veins: They glowed red when he was enraged.
- Woobie, Destroyer of Worlds
- Worthy Opponent: Calls Erin one after their fight.
- Would Hurt a Child: Played with. Clayton is genuinely horrified that he was tricked into slaughtering hundreds of Roman demigods (many of whom were likely teenagers), but he has no problem destroying the modern-day campers of Camp Half-Blood.
A son of Poseidon who acts as a spy for Clayton and serves as his right-hand man. He is driven by his own motivations to destroy the gods.
Tropes that apply to Jace:
- Blood Knight: He shows shades of this whenever fighting the Olympians or camp is involved.
- Dies Wide Open
- The Dragon: He is this for Clayton.
- Evil Counterpart: Whether intentional or not, he can easily be this to Percy Jackson. Both are sarcastic sons of Poseidon who adored their mothers and are almost unhealthy dependent on a female friend/Love Interest of theirs. The difference is while Percy was introduced to camp at an early age and was able to save his mother, Jace's mother died and he spent years living on the streets growing to resent the gods for abandoning him and his mother.
- Impaled with Extreme Prejudice: How Dusk kills him.
- Jerkass: To everyone except for Chloe.
- Living Emotional Crutch: Heavily implied to be this for Chloe.
- Making a Splash: Par the course for children of Poseidon.
- The Mole: He becomes this for Clayton almost immediately before the final quest kicks off.
- Morality Pet: Chloe was this for him, but it wasn't enough.
- Self-Made Orphan: As the gods are forbidden to actually interact wit and raise their children, Jace only had his mother. It's implied in his backstory that he caused the storm which killed her, though not intentionally.
- Street Urchin: Part of his backstory.
Goes by Cal, he is a son of Aeon and the first love interest of Faith. Though he did not found the Ronins, he leads their assault during their assault on Camp Half-Blood and is killed by Hannibal. He is resurrected and serves as a protagonist in Dream Of The Dead.
Tropes that apply to Cal
- Earn Your Happy Ending: He eventually is granted access to Elysium after redeeming himself in Dream of the Dead.
- Klingon Promotion: How he took over the Ronins—he killed his predecessor.
- Love Makes You Evil: He begins his war against Olympus because the girl he loved, Faith, died. By the time she was resurrected, he was too far gone to stop.
- Time Master: Not to the same extent as the Hierophant, but Cal could slow down time around him, using it to his advantage in battle.
Eteocles Krónidis/The Hierophant
A demititan son of Kronos, the Hierophant is the last member of the Golden Age race of humans who lived during the First Age of Man. He spent centuries at a time hibernating, and founded the Covenant, and anti-Olympian cult which was eventually wiped out, but its legacy founds the modern-day equivalent, the Ronins. When the Hierophant awakes, he launches a campaign to destroy Olympus.
Tropes that apply to the Hierophant
- Bad Boss: It is revealed that he took the last few hundred members of the Covenant, his loyal followers, and horrifically stripped their souls from their bodies and implanted them into the first Celestials.
- Badass: You automatically are one if you can duel and defeat Apollo with your fists.
- Big "NO!": He screams one right before he dies.
- Dark Messiah: He considers himself the savior of demigods, and even founded a cult during his millenia spent on the earth.
- Defeat Equals Explosion: He explodes upon being stabbed with the Spear of Destruction, leaving nothing behind but a helmet.
- Greater-Scope Villain: His appearance kicks off the next two plots after his death, since Golden Age artifacts begin to activate and get discovered.
- Hero Killer: He has the highest body count of any antagonist so far.
- Hoist by His Own Petard: His haste to kill Hunter led to him accidentally piercing his own armor, allowing Tempest to stab him.
- Impaled with Extreme Prejudice: How Tempest kills him with the Spear of Destruction.
- Jerkass Has a Point: If you know your mythology, he's not actually wrong when he says the Olympians cheated destiny. Zeus was supposed to have a son which would eventually overthrow him, but he swallowed Metis before she could become pregnant with him. The Hierophant saw this as an affront to the universe.
- Last of His Kind: He is the last Golden Age human left alive.
- Nigh Invulnerable: He can take an incredible amount of punishment. He gets tackled through a mountain, lit on fire and propelled into the earth with the force of a small comet, and the only thing that happens is...one of the eye-pieces in his helmet cracks. It becomes a plot point in Earthfall.
- Non-Action Big Bad: Played with. He doesn't shy away from combat, and the Celestials do most of his fighting for him. But he does significantly less fighting than any of the other antagonists, and is so invulnerable that he can basically stand around and let people hammer away at him uselessly. Until Hunter attacked him, he sat there and directed his troops during the final battle.
- Offscreen Moment of Awesome: We never actually see his takeover of Olympus, it happens before the story begins.
- Physical God: He is, by far, the single-most powerful antagonist as of yet.
- The Faceless: Though his physical appearance is given a description, he is never actually seen at all during the story. He wears a hooded cloak during his first appearance, and then his armor, which has a helmet.
- Time Master: He used this to drastically extend his own life, and displays time-manipulating abilities in battle.
Sentinel/ Thomas Carter
A crime-lord who appeared in between the third and fourth plots, Sentinel was originally a minor villain, a mortal man who ruled the global criminal underworld. When Peter and Jolon began to act as vigilantes and attempt to clean up the city, they inadvertently targeted a number of his own high-ranking employees. Eventually, Sentinel was forced to step into the open, revealing his lresence. He laid siege to Manhattan, killed Peter (who got better) and traumatized Jolon into retiring. Though technically defeated, he was unmasked as Veronica's philanthropic father and subsequently managed to clear his own name. He upgrades to the antagonist of Earthfall, now seeking the Harvester, an ancient Golden Age superweapon.
Tropes that apply to Sentinel
- Crazy-Prepared: In his first appearance, he rigged the skyscraper in which he had his final battle with Peter with C4, in case Peter proved too much.
- Villainous Breakdown: Subtle, but it's there. He's much more eager for open confrontation than he was during his first appearance.
- The Bad Guy Wins: He is the only villain who is shown consistently winning in his confrontations with the heroes.
- Finally averted in Earthfall, where he's been trounced twice in a row.
