History Characters / TheCampHalfBloodSeriesForcesOfGaia

* BerserkButton: Never mention GlobalWarming around her.

* EldritchLocation: Tartarus the location is his body, with all that implies. The ground is flesh, rivers of horrific properties flow across and under the land, the air is poison, and monsters crawl from the living soil. Even ''that'' horrific place is just AFormYouAreComfortableWith, with many successive layers existing simultaneously in the same space, so mind-numbingly horrible that even before you get to the true destroy-you-if-you-look-at-it form you'll be driven mad. On top of that, this entire place is floating in an endless black void that's somehow ''worse''.

''The'' Tartarus, a manifestation of the darkest part of the Underworld.

[folder:Tartarus]]

!!Gigantes (The Giants)

[[folder:Porphyrion]]
The most powerful of the giants and their king. Deigned to be a direct counter to Zeus including power.

* ArchEnemy: To Zeus.
* AuthorityEqualsAsskicking: When at full strength.
* BladeOnAStick: His main weapon
* CurbStompBattle: In the last book, [[spoiler: He is on the receiving end of one at the hands of Zeus and Jason. Zeus nearly kills him with his Master bolt before Jason blows him off a cliff and Zeus uses another lighting blast to reduce him from ash. His own spear is sliced in half and he fails to mount any sort of defense or offense.]]
* TheDragon: To Gaia.
* LargeAndInCharge: Described as the tallest of the giants and the most built physically.
* OrcusOnHisThrone: Is resurrected in the first book only to do nothing over the next four while the heroes steadily advance toward him. Any actual planning or action is taken by Gaia.

[[folder:Polybotes]]
Counterpart to Poseidon.

[[folder:Tartarus]]
''The'' Tartarus, a manifestation of the darkest part of the Underworld.

* AdaptationalVillainy: Tartarus is not a bad guy in myths, not even the [[EverybodyHatesHades Hades-kind]] bad guy. He's a sort of a static character who functions more as a locale (being the worst prison for any being), and his relationship with Gaea that produced Typhon is a strictly a one-shot affair with no indication that he hopes it would be used against the gods.
* ArchnemesisDad: To Damasen.
* AttackOfThe50FootWhatever: As with all other protogenoi.
* BigBadDuumvirate: Implied by his dialogue, and a logical conclusion given that he fathered the Giants with Gaia and is by far the most powerful of her affiliates.
* TheBlank: A variation. He doesn't have a face, but he doesn't have a blank patch of skin either. What he does have is a nightmarish combination of whirlpool and black hole.
* BodyHorror: [[EldritchLocation The entirety of Tartarus is his]] ''[[EldritchLocation body]]''. This is given nods throughout the book as Percy and Annabeth joke about how they're traversing across different parts of his anatomy.
* DarkIsEvil: Oh, you had better believe it!
* DisproportionateRetribution: Destroys [[spoiler:Krios and Hyperion]] for the former describing him in an unflattering manner.
* TheDreaded: For very good reason. It takes [[spoiler:a YouShallNotPass by Bob and Damasen to slow him down long enough for Percy and Annabeth to escape. What, exactly, do you think happened to them afterwards?]]
* EldritchAbomination: The realm of Tartarus is his body, and when he [[HumanoidAbomination assumes a form to deal with them personally]] Percy and Annabeth have a hard time looking directly at him.
* EldritchLocation: Tartarus the location is his body, with all that implies. The ground is flesh, rivers of horrific properties flow across and under the land, the air is poison, and monsters crawl from the living soil. Even ''that'' horrific place is just AFormYouAreComfortableWith, with many successive layers existing simultaneously in the same space, so mind-numbingly horrible that even before you get to the true destroy-you-if-you-look-at-it form you'll be driven mad. On top of that, this entire place is floating in an endless black void that's somehow ''worse''.
* FightingAShadow: The manifestation at the end of the book is simply a form he assumed to deal with the Heroes. His true form ''is'' the locale of Tartarus.
* GeniusLoci: Tartarus' body is pretty much the Greek version of Hell.
* KickTheDog: We probably weren't supposed to feel bad for [[spoiler:Hyperion and Krios]], but his reason for doing what he did to them just makes it callous.
* KnightOfCerebus: Twofold. [[spoiler:Percy and Annabeth]]'s trek across Tartarus (technically his body) is easily one of the darkest parts of the book, and things naturally get worse when he shows up in person.
* MightyGlacier: Is slow but immensely powerful, due to never having taken on a humanoid form before.
* MonsterProgenitor: Fathered Typhon, Kampê, and the giants with Gaia
* OffingTheOffspring: Presumably did this to [[spoiler: Damasen and Bob.]]
* OrcusOnHisThrone: He fathers monsters with Gaia and serves as a respawn point for all monsters, but he doesn't really get involved himself. At the current point in time, he's only formed a corporeal form once. [[spoiler: In fact, he doesn't participate in the final battle.]]
* RealityEnsues: He assumes an incredibly powerful humanoid form to crush Percy and Annabeth...and is barely able to walk, since he's a GeniusLoci and has never done it before.
* RelatedInTheAdaptation: Depending on the source, in some of the original myths Tartarus didn't father the giants (they're generally described as springing from Ouranos's blood in such tellings), nor was he actually married Gaea (though he did have an intimate relationship with her).
* ThePowerOfTheVoid: Everything about his physical description. He has VoiceOfTheLegion that echoes inwards instead of outwards, a vortex for a face that absorbs essences and Annabeth describes the environment as looking like it's being pulled into him.
* TheUnfought: The heroes never even ''try'' to touch him, while [[spoiler: Damasen and Bob's sacrifices]] simply distract him long enough for the heroes to flee before [[spoiler: Tartarus possibly kills them.]] Thanks to this, [[spoiler: he's one of Gaea's two major allies (alongside Python) to survive the Second Gigantomachy.]]
* UnskilledButStrong: Thankfully, for all his power, he's clearly unused to combat in a corporeal form, a weakness the heroes are able to exploit. Justified, though, as he'd never summoned a physical manifestation of himself before this point, and was essentially taking his baby steps.
* WombLevel: The realm of Tartatus is his body.
[[/folder]]

[[folder:Kymopoleia]]
Goddess of sea storms. For related tropes, see [[Characters/TheCampHalfBloodSeriesMinorGods here]].
[[/folder]]

!!Titans
[[folder:Koios]]
The titan of the North, foresight and knowledge.
----

* GettingCrapPastTheRadar: "Schist!"

[[folder:Aeolous]]

* AscendedExtra: Like Lityerses, Medea is a much more prominent antagonist in ''TheTrialsOfApollo'' than she was in ''The Lost Hero''.

* AesopAmnesia: Defied. He never really learned the anti greed lesson his story is often used to teach to begin with. He simply learned how to reverse the unintended consequences of his gift.

* ArchEnemy: To Hades. Also to Hazel, seeing as she was the one who was manipualted into resurrecting him.

* FrickinLaserBeams: Not himself, but he bought a few to protect the airspace over his home.

* GemTissue: Is covered in various precious jews and metals, in fact his very own heart is a made of diamonds.

* WalkingTechbane: Specifically invoked, as he was made to counter the god of technology. Around him, "maps are misread, devices break, data is lost, and the finest minds turn to mush" (which is why Annabeth has such a hard time with him).

Midas's son.

* PokeInTheThirdEye: Every time Percy sees her in a dream he wakes up when she detects and lunges for him.

* HairDecorations: Like most Giants. His "decorations" of choice are weapons (implied to be those of past enemies).

* HairDecorations: He has ''live basilisks'' slithering in his hair.

* HairDecorations: He has bones braided into his hair.

* HairDecorations: Gold and silver coins, and, at one point, [[TemptingFate fireworks]].

* HairDecorations: An [[AvertedTrope aversion]] among giants; he has no special decorations. The only unusual thing is that the braids appear to be made of smoke.

* {{Yandere}}: Ur-Example.

* WinterRoyalLady: The goddess of snow.
* WomanInWhite: Wears a white silk gown.

* WoundThatWouldNotHeal: As a ghost, he's forever trapped to appear as he was when he died.

* VilalinousCrush: Sump develops one on Piper.

* WoundThatWouldNotHeal: He still has Odysseus's arrow sticking out of his neck and none of his other wounds ever close.

* FinalBoss: Of ''The Mark of Athena''.

* GoodCOlorsEvilCOlors: They glow red.

Tired of the rule of her descendants the gods and angered by the murder of her children the titans, Gaea, goddess of the Earth itself, seeks to rise once more.

* CurbStompBattle: In the last book, [[spoiler: Both gives and receives one. He fights Percy in the water and his poison instantly takes Percy out, but is on the receiving end of one from Jason and Kymopoleia. And he only won the Percy battle because Percy intentionally swam into the poison because he felt he deserved to be punished for prior actions.]]
* HairDecorations: He has ''live basilisks'' slithering in his hair.
* InformedAbility: Supposed to be the anti-Poseidon. Percy proceeded to open up a can of [[CurbStompBattle 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.
* PaperTiger: All of the giants vastly over-exaggerate themselves one way or the other, but Polybotes is the worst. Despite his frighting appearance and and status as the anti-Poseidon he is stymied by minor goddesses defeated relatively easily in single-combat with demigods. Especially hilarious in the second time it was underwater, which should have been his domain, against a child of the sky.
