History Characters / TheCampHalfBloodSeriesMinorGods

Goddess of youth. Her cabin in Camp Half-Blood is Cabin 18.

* FountainOfYouth: She runs a club in Times Square where boomers and millennials alike can experience being young again.

* TheFriendNobodyLikes: The rest of the gods either hate or fear him, because he represents that they should have been if not for their godly powers: frail and ugly.

-->'''Jason''': Is this guy Love or Death?
-->'''Cupid''': Ask your friends. Frank, Hazel, and Percy met my counterpart, Thanatos. We are not so different. Except Death is sometimes kinder.

--> '''Cupid''': Love is no game! It is no flowery softness! It is hard work- a quest that never ends.

--> '''Cupid''': Love is on every side. And no one's side. Don't ask what love can do for you.

* EverythingsBetterWithRainbows: As the goddess of rainbows she's cheery and perky.

* NiceGirl: Unlike virtually every other god or goddess she lacks the arrogance, personality quirks or JerkAss qualities that make dealing with the other ones such a pain. She is helpful without having to dance through flaming hoops.

* CainAndAbel: [[RunningGag She joins the list of Percy's siblings who have tried to kill him.]]

* TheUnfavorite: Her parents keep her away because they find her presence and powers disruptive.

* DeathByIrony: A fan of inflicting it. Ask Narcissus...as soon as he stops looking into his mirror.

* SplitPersonality: [[AvertedTrope Averted]]. Revenge is universal, and her name remains the same [[note]]She may be equated with Invidia though.[[/note]] whether Greek or Roman, rendering her immune to the debilitating effects of the war.

* CompetitionFreak: Obsessed with victory in all its forms, which makes her case of the divine schizophrenia much harder to handle as she's so desperate to pick a winner between her two sides that she's much more volatile as a result. According to Percy and Annabeth this is a trait she shares with her children.

!!!'''Played by''': Creator/RosarioDawson

* Note: Since an exact definition is very hazy, only the first and second generations of Titans are listed here (aside from the Olympians).

* AscendedExtra: Several of the titans shown are hardly even known to the public.

* JerkassGods: Just like most of the gods only in most cases worse.

* EvilIsBurningHot: While Helios is not really evil, his fire is described to be white-hot, pure, and merciless. His powers are also used by Medea, who is certainly evil.

* ThePollyanna: Name means "Bright" which was how she tried to see the world.

* BeingGoodSucks: In ''Greek Gods'', Percy uses language similar to describing his own mother, in that Rhea had the nicest sweetest personality of out of the Titans, which meant she got the worst luck, such as having Kronos fall for her and having him swallow her children.

* SophisticatedAsHell: Rhea's ominous warnings about the rise of the Triumvirate is mixed in casual slang from the sixties.

* BirdsOfAFeather: She (rivers and streams) marries Oceanus (the ocean). "Hey you like water? I like water too! We should totally go out!"

* TheDitz: Theia is... not too bright. Which is ironic considering she is the Titan of bright and shiny things.

* UnwittingPawn: To [[spoiler:Khione.]]

* FaceHeelTurn:[[spoiler:Between appearances, Khione seems to have turned him to Gaia's side. Though this could just be her manipulating his fragile state of mind and body, as he's back on the gods' side by the finale.]]
* FrenchJerk: Of the French-Canadian variety, actually.

* UnwittingPawn: To [[spoiler:Khione.]]

* BackForTheFinale: [[spoiler:Cameos while pulling Zeus's chariot in ''The Blood of Olympus.'']]

* HotBlooded: Notus.
* TwoRoadsBeforeYou: Auster hates indecisiveness, and insists that he won't help Jason until he decides [[spoiler:between Greek or Roman.]]

* BackForTheFinale: [[spoiler:Pulls Zeus's chariot in ''The Blood of Olympus.'']]
* CrazyJealousGuy: Murdered the guy he was in love with out of jealously.
* IfICantHaveYou: Was in love with [[PrettyBoy Hyacinthus]] and was jealous of the god Apollo's closeness to him, so when Apollo and Hyacinthus were playing a game Zephyros arranged for the disc to strike Hyacinthus. He doesn't seem too hung up about it, though.

* SitcomArchnemesis: With Hudson River.

* SitcomArchnemesis: With East River.

* HeartIsAnAwesomePower: She's in charge of nets for hunting and fishing only. Just like in the source material, she can make some pretty elaborate nets- apparently beat traps and booby traps qualify by extension.

Son of Aphrodite/Venus and god of love. To date only his Roman form has been seen.

* LadyOfBlackMagic: UrExample.

Goddess [[note]] Openly admits to actually being a Titan though.[[/note]] of magic and crossroads. Her cabin in Camp Half-Blood is Cabin 20.

[[folder:Harpocrates]]
Originally an Egyptian deity and a protector of children, later reimagined by the Greeks as a god of secrets.

* CessationOfExistence: [[spoiler:This is how he goes out, having willed himself to fade into Chaos.]]
* ClapYourHandsIfYouBelieve: His conception as a deity was the Greeks mistaking the Egyptian symbol for youth they saw on a statue of Horus for a hushing gesture. When Meg doubts this, Apollo states the power of belief from thousands of people should not be underestimated.
* FingerMuzzle: He is stuck in this position, due to all his statues showing him as such. It's also the reason he was reimagined. The Egyptians use it as an indication of youth and childhood; the Greeks thought it was a hushing gesture, hence reimagining the deity as a god of secrets and silence.
* HeroicSuicide: [[spoiler:Along with the Cumaean Sibyl, he willingly [[CessationOfExistence fades]] so his final breath can be used for the ritual to summon divine help.]]
* MindRape: Communicates with telepathic blasts, due to his aura of silence.
* SilentAntagonist: Justified, since he's literally the god of silence. He also generates a bubble of absolute soundlessness around himself. The Triumvirate use magic to amplify this effect to block demigods' communications.

[[folder:Hecate/Trivia]]
Goddess [[note]] Openly admits to actually being a Titan though.[[/note]] of magic and crossroads.

* AscendedExtra: Only gets a few mentions in [[Literature/PercyJacksonAndTheOlympians the previous series]], but plays an important role in ''Son of Magic'' and ''The House of Hades''.
* AtTheCrossroads: Hecate is the goddess of crossroads, and as such can predict possible outcomes each choice will lead into. [[spoiler:In ''The House of Hades'', she shows Hazel three possible outcomes their crew could end up with given their precarious situation, and none of them are pretty.]]
* CanineCompanion: Apparently, she turned Hecuba, the former Queen of Troy, into a Labrador.
* HeelFaceRevolvingDoor: Born a Titan and served the Olympians in the first war, but is remembered for her stint on the Titan's side in the previous series (although this was pretty justified given how the gods treated her). She's now back on the gods' side, although to what extent is ambiguous.
* JediMindTrick: Notable for being the best Mist manipulator the series has seen so far, due to it being part of her powers.
* LadyOfBlackMagic: UrExample.
* LooksLikeCesare: Beautiful, but deathly pale. Hazel compares her to a dead body.
* MagicIsFeminine: Hecate is the Greek goddess of magic and the maintainer of the [[PerceptionFilter Mist]] that keeps mortals from discovering TheMasquerade. She trains Hazel (one of three girls on the team) in how to use magic and manipulate the Mist to her own ends.
* MatchstickWeapon: Her two torches. She used them in the original Giant War to kill Clytius. She uses them to kill Clytius again in ''House of Hades''.
* NeutralFemale: In ''Son of Magic'' (a short story in the Demigod Diaries), she stays out of Alabaster's fight against Lamia, and only intervenes [[spoiler:when he's about to trap Lamia in her own sand]]. [[JustifiedTrope Justified]]; she's a god and both Alabaster and Lamia are her children, so she can't play favorites.
* UhOhEyes: Hazel describes them as [[BlackEyesOfEvil black]] and creepy; although Hecate asserts that she isn't ''evil'', magic, her domain, is merely a tool.
* YouRemindMeOfX: Tells Hazel that she's a lot like her mother.

[[folder:Heracles/Hercules]]
Child of Zeus who ascended to Godhood as a minor god who guards the doors of Olympus. Previous owner of Percy's CoolSword.

* BerserkButton: The very mention of Hera will piss him off. [[spoiler:He was nice and friendly to his half-brother Jason, hating to give hard quests since he was once a demigod...right up until he mentioned Hera's name. Then he gave them a really hard one and threatened to kill everyone on the Argo II.]]
* BrokenPedestal: Heracles was Percy Jackson's favorite hero, mostly because he admired how he had rotten luck in his old demigod life, much like his. But then he learns from [[spoiler:Zoe Nightshade that he convinced her to betray her family and [[UngratefulBastard instead of thanking her for helping him, he stole credit for everything she did and left her to face the wrath of the Hesperides and her father, Atlas]].]] This causes Percy to lose some respect for his favorite hero.
* CoolSword: He owned Riptide before Percy.
* JerkWithAHeartOfGold: Hercules is usually more benevolent towards demigods than most other gods since he knows first hand what a pain it is to constantly go on quests, slay monsters, and put up with the other Olympians. The jerk part comes out with anything involving Hera since she tormented him all his mortal life and upon death he was sent to an island with nothing to do but reflect on his past...which he can never forget.
* KickTheDog: He once used a river to wash out the horse poop from Geryon's stables, causing the naiad who lived in it to be sick for years. She's still bitter about it.
* RevengeBeforeReason: He absolutely ''refuses'' to do anything that could possibly benefit Hera in any way. This is pretty justified, considering all the hell she put him through in his lifetime.
* SuperStrength: His most famous trait.
* WalkingShirtlessScene: Played for laughs; in the past he was apparently naked so much that the dwarves who stole from him called him "Black Bottom."
* WhoWantsToLiveForever: He laments that eternal life only means that he'll never forget his pain.

[[folder:Iris/Arcus]]
The goddess of rainbows and a messenger goddess. She used to run the Iris Messaging service, but has turned over most of it to her assistant Fleecy to focus on running her store and developing an identity of her own. Only Iris has been seen, with no mention of Arcus even existing.

* AscendedExtra: Doesn't make an actual appearance in the [[Literature/PercyJacksonAndTheOlympians first series]], but gets a supporting role in ''Son of Neptune''.
* DidYouJustFlipOffCthulhu: Enemy forces are surrounding her store, the giant Polybotes leading them. She throws a ding-dong at him.
* EverythingsBetterWithRainbows: As the goddess of rainbows she's cheery and perky.
* NiceGirl: Unlike virtually every other god or goddess she lacks the arrogance, personality quirks or JerkAss qualities that make dealing with the other ones such a pain. She is helpful without having to dance through flaming hoops.
** A bit less so in her second appearance in ''The Chalice of the Gods''; while she is still largely friendly and ultimately helps the heroes out, she does make Percy undergo a somewhat-dangerous quest for her in exchange for her aid on the quest he was ''already'' undertaking (and when he succeeds, her happiness is directed more at her symbol of office that Percy cleaned and less at Percy for actually cleaning it). Percy even observes when on the way to meet with her that even the nicer gods can be fickle, and having had ''one'' relatively positive interaction is no guarantee for the future.
* GranolaGirl: She is trying to find her own identity and currently working with an environmentalist-hippie outlook which is what her store represents.

[[folder:Janus]]
Roman god of choices. For related tropes, see [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].

[[folder:Keto]]

* AttentionWhore: Joined Gaia to make the world remember her again.
* CainAndAbel: [[RunningGag She joins the list of Percy's siblings who have tried to kill him.]]
* DudeWheresMyRespect: Despite being an incredibly powerful goddess, she despairs over not getting the recognition she deserves.
* HeelFaceTurn: Jason wins her over by promising to erect shrines to her and the other minor gods at the Greek and Roman camps.
* InUniverseNickname: Jason and Percy just call her "Kym."
* TheMentor: She's the one who reveals to Jason and Percy how to defeat Gaia [[spoiler:by reminding them of how Ouranos, a fellow primordial god and First Lord of the Sky, was ultimately defeated]]. She also warns Percy of his FatalFlaw once again.
* UnderwaterRuins: She makes her lair in the abandoned wreckage of her father's old palace.
* TheUnfavorite: Her parents keep her away because they find her presence and powers disruptive.
* UnwantedSpouse: She was married off to Briares, whom she loathes. Granted, it's not for his personality, as Briares is a NiceGuy overall, but more for the fact the marriage was forced on her.

[[folder:Melinoe]]
Goddess of ghosts. For related tropes, see [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].

[[folder:Morpheus/Somnia]]
God of dreams. For related tropes, see [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].
[[/folder]]

[[folder:Nemesis]]
Goddess of Revenge.

* DeathByIrony: A fan of inflicting it. Ask Narcissus...as soon as he stops looking into his mirror.
* EmpathicShapeshifter: She takes the form of those others want revenge on. Leo sees his Aunt that called him a Devil Child for causing her sister's death. Hazel sees her as a long dead SternTeacher.
* EquivalentExchange: In the original series, she took Ethan's eye to influence Camp Half-Blood's victory. In ''Mark of Athena'', she offers the same for Leo, a heavy price for her help should he need it. [[spoiler:Leo uses her offer to save Hazel and Frank's lives... which comes at the cost of trapping Percy and Annabeth in Tartarus.]]
* ScalesOfJustice: One of her symbols. [[spoiler:Her son Ethan is buried with them embroidered on his shroud.]]
* SplitPersonality: [[AvertedTrope Averted]]. Revenge is universal, and her name remains the same [[note]]She may be equated with Invidia though.[[/note]] whether Greek or Roman, rendering her immune to the debilitating effects of the war.
* WindsOfDestinyChange: Nemesis tears down those who have too much good luck, and raises up those who have too much bad luck.
* YouCannotGraspTheTrueForm: To any individual person, she looks like a specific person that they want revenge against.

[[folder:Nike/Victoria]]
Goddess of victory and charioteer to Zeus.

----
* BoundAndGagged: After being successfully subdued by the Seven she's tied up and kept in the ''Argo II''. The fact that her "gag" is a dirty sock and duct tape is given much emphasis.
* CompetitionFreak: Obsessed with victory in all its forms, which makes her case of the divine schizophrenia much harder to handle as she's so desperate to pick a winner between her two sides that she's much more volatile as a result. According to Percy and Annabeth this is a trait she shares with her children.
* RockMonster: Her minions, the Nikai (or "Nikettes" as Leo christens them), are metal women.
* WingedHumanoid: Her preferred form has two large golden wings.

[[folder:Pan/Faunus]]
The lost god of the wild, believed to have been dead for two thousand years.

* AlwaysSomeoneBetter: Gaia, introduced in the ''Heroes of Olympus'' series, holds sway over domain similar to his but with much more power.
* DeathSeeker: [[spoiler:Wanted to fade because of the decline in the wild places of the earth, and let the world believe he was dead so he would fade faster, but [[GodsNeedPrayerBadly since the satyrs believed in him]], he couldn't fade yet.]]
* FriendToAllLivingThings: As per his role of god of the wild.
* GodIsDead: Claimed many centuries ago, though the satyrs don't believe it. [[spoiler:Becomes true as of ''Battle of the Labyrinth''.]]
* GreenThumb: Nature is part of his domain.
* HesJustHiding: In-universe, Grover does not believe Pan dead and his main motivation throughout the series is to gain a Seeker's license so he can find Pan.
* MagicMusic: Music played on his reed pipes can make plants grow.
* PassingTheTorch: [[spoiler:He passes his role on to every mortal, satyr, and nature spirit in the world.]]
* SmallRoleBigImpact: He only has one short appearance but his mere existence has driven the satyrs for centuries and Grover personally for all previous books.

[[folder:Persephone/Proserpine]]
!!!'''Played by''': Creator/RosarioDawson

[[quoteright:266:https://static.tvtropes.org/pmwiki/pub/images/persephone_apringtime.jpg]]
Goddess of springtime, Demeter's daughter, and Queen of the Underworld. Married to Hades.

* BigEater: At least according to Apollo's rather gossipy internal monologue:
-->'''Apollo:''' You'll hear stories about the goddess of springtime being all sweetness and daffodils and nibbling on pomegranate seeds, but I'm telling you, that girl was frightening when she attacked a mound of pork spareribs.
* ChildByRape: She was conceived when Zeus cornered her mother and forced her to have sex.
* ClingyJealousGirl: A milder example than Hera, but she doesn't like it when Maria di Angelo is brought up. [[note]]Actually a carry-over from the original mythology, where she turns Hades's ex-mistress into a [[JustSoStory the first mint plant]].[[/note]]
* DishingOutDirt: Splits open the earth in ''The Demigod Files''.
* EtherealWhiteDress: The otherworldy, deathly aspect. While in the Underworld and Hades's queen; she wears a washed-out white dress. When she's out of it, her attire is very colorful.
* GoodStepmother: As noted below, she was initially a WickedStepmother but by ''The Sun and The Star'' she not only admits to Will that she didn't treat Nico right but goes out of her way to give Will advice about Nico and how to make their relationship work, showing a surprising amount of insight and understanding for her stepson. She even let Will keep the pomegranates they stole.
* GreenThumb: She double teams with her mother to attack the Titans' army with wheat and flowers.
* HappilyMarried: To Hades, more or less. [[note]]Actually a carry-over from the original mythology, most stories mention that she preferred Hades over Demeter.[[/note]] Certainly so by Greek standards.
* LadyMacbeth: Goes behind Hades' back to try and ensure he's just as powerful as Zeus and Poseidon. One of the reasons Nico decides to spend more time in the Underworld is so that he can counteract Persephone's influence.
* NoodleIncident: In ''The Demigod Files'':
-->'''Persephone:''' We just had a little family spat.\\
'''Nico:''' ''Family spat''? You turned me into a dandelion!
* RaceLift: Implicitly white in the books; AmbiguouslyBrown in the films.
* RavenHairIvorySkin: Described as such during her time in the Underworld.
* WickedStepmother: To Nico with whom she has a very strained relationship. She apparently turned him into a dandelion at one point. She's moved past this by ''The Sun and The Star'' however.

[[folder:Phorcys]]
God of the dangers of the sea. For related tropes, see [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].

[[folder:Pomona]]
Roman goddess of plenty. For related tropes, see [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].
[[/folder]]

[[folder:Terminus]]
The exclusively Roman god of boundaries. His tropes can be found [[Characters/TheCampHalfBloodSeriesCampJupiter here]].
[[/folder]]

[[folder:Thanatos/Letus]]
The god of death.

* CompellingVoice: His voice is deep and sonorous.
* DarkIsNotEvil: He's the God of Death with large black wings but pretty chill and reasonable. He's not malicious, death is just his job.
* DistressedDude: In ''Son of Neptune'', the whole point of Percy, Hazel, and Frank's quest is to rescue him from Alcyoneus.
* DontFearTheReaper: Not particularly gentle and a ScaryBlackMan with some shades of TheStoic, but obviously not malicious or cruel. Indeed, he's really quite polite to the demigods.
* GoodIsNotSoft: He's on the side of the gods, but he ''is'' Death.
* GoodWingsEvilWings: Has a pair of black angel wings, specifically.
* TheGrimReaper: As the god of death, this is essentially his job.
* LiteralMinded: When Hazel implores him to help the demigods fight an army of undead spirits, he replies that he is, by ensuring that the spirits they slay will remain dead. When she thanks him sarcastically, he replies with, "You're welcome."
* NumberTwo: Lieutenant of Pluto (Hades). Thanatos acts as border control to keep souls from crossing between life and death without his permission.
* PrettyBoy: Hazel calls him the prettiest man she's ever seen.
* ProductPlacement: Uses an iPad to keep track of the dead.
* ScaryBlackMan: Somewhat, although he's just doing his job.
* TheStoic: Merciless and seemingly emotionless.
* WingedHumanoid: His preferred form has a pair of large black wings.

[[folder:Triptolemus]]
A man who found favor with Demeter and was raised to a minor farming god.

* CloudCuckooLander: Turned Nico into a cornstalk, for one.
%%{{Jerkass}}: A minor one.
* SeriousBusiness: Woe betide anyone who doesn't consider agriculture as important as he does.

!!The Titans
* Note: Since an exact definition is very hazy, only the first and second generations of Titans are listed here (aside from the Olympians).
[[folder:In general]]
A series of deities who preceded the Olympians as rulers of the universe. The eldest of the [[Characters/ClassicalMythologyTitans Titans]] are children of Gaea, the primordial goddess of the earth, and Ouranos, the primordial god of the sky. Their domination ended when the Olympians overthrew their king, Kronos, and exiled him to Tartarus. The majority of the male Titans supported Kronos and were therefore exiled with him, while others supported the Olympians or remained neutral and as a result were allowed to live as minor gods. Other than the Olympians, many other gods have some amount of Titan ancestry.

----
* AFormYouAreComfortableWith: Justified, as anyone seeing them in their true forms would probably be crispy-fried in an instant.
* AscendedExtra: Several of the titans shown are hardly even known to the public.
* GodNeedsPrayerBadly: It's brought up several times that Helios and Selene, Titans of the Sun and Moon, faded away entirely after the Romans reassigned their domains to Apollo and Artemis.
* InhumanlyBeautifulRace: Unless otherwise stated or if the narration says they cross into UncannyValley despite their beauty, you can expect a titan's preferred form will be extremely easy on the eyes.
* JerkassGods: Just like most of the gods only in most cases worse.
* MayflyDecemberRomance: Any that have any demigod's are this with the mortal parents.
* TheOlderImmortal: They are older than the Olympians, but younger than the primordial gods. The eldest four of the Olympians (Zeus, Poseidon, Hera, Demeter), plus Hestia and Hades, are children of two Titans, Kronos and Rhea.
* OurTitansAreDifferent: Not too different from the Gods themselves, but older and often larger.
* SadlyMythtaken: The common mistake of treating the Titans as a separate race entirely from the gods rather than simply a group of gods (in spite of retaining the familial connections).
* VoluntaryShapeshifting: All of them can change their appearance at will, and hence have "preferred" forms.
* YouCannotGraspTheTrueForm: Titans take different shapes due to the fact that their true forms will incinerate anyone who sees them as such.

----

[[folder:Atlas]]
The Titan son of Iapetus who was forced to carry the heavens on his back. He is the father of Calypso and the Hesperides, including Zoë Nightshade. His tropes can be found [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].

[[folder:Helios/Sol]]
The Titan of the Sun and the son of Hyperion. He is the father of Circe and Pasiphae and the grandfather of Medea. He had faded millennia ago, with Apollo succeeding him as the master of the Sun.

* CessationOfExistence: Gods who fade away will return to the Chaos AKA nothingness. ''The Burning Maze'', however, reveals that Helios manages to tether his will on Earth due to pure hatred. [[spoiler:Once Medea is killed, Apollo manages to convince him to move on.]]
* ChekhovsGunman: Already has mentions since the first series, he becomes an important figure in ''The Burning Maze''.
* EvilIsBurningHot: While Helios is not really evil, his fire is described to be white-hot, pure, and merciless. His powers are also used by Medea, who is certainly evil.
* GreenEyedMonster: He resents Apollo for taking his place and dooming him into a life as a shadowy figure. [[spoiler:Or so it seems. In actuality, he became a shadowy figure because Medea restrained him from dissolving into Chaos]].
* ThePowerOfHate: It's explicitly mentioned that he is able to escape succumbing to the Chaos due his extreme hatred of Apollo. [[spoiler:Or rather, Medea.]]
* ThePowerOfTheSun: It's in his name. Apollo describes that while he is merely a god who dabbles in the Sun, Helios personifies the Sun itself. While Apollo can limit himself to only show the Sun's good side (warmth, life-giver), Helios embodies everything about it, including its dark side (distance and resentment).
* UsedToBeASweetKid: Before he ceased to exist, anyway. Apollo implies that he was an all-around good guy, being one of the few male Titans who sided with the Olympians during the Titanomachy. Now, he is so much filled with anger that the first thing he says to Apollo when the two meet after his cessation is [[spoiler:to kill his granddaughter.]]
* WalkingWasteland: When Medea moves her grandfather's essence to the Labyrinth below Southern California, the area slowly turns into {{Mordor}}.

[[folder:Hyperion]]
The Titan of light, father of Helios. His tropes can be found [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].

[[folder:Iapetus]]
The Titan of mortality, father of Atlas and Prometheus. His tropes can be found [[Characters/TheCampHalfBloodSeriesServantsOfTheGods here]].

[[folder:Koios]]
The Titan of knowledge, father of Leto, and grandfather of Apollo, Artemis, and Hecate. His tropes can be found [[Characters/TheCampHalfBloodSeriesForcesOfGaia here]].

[[folder:Krios]]
The Titan of stars and constellation, grandfather of the Anemoi, Hecate, and Nike. His tropes can be found [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].
[[/folder]]

[[folder:Kronos/Saturn]]
The King of the Titans who presides over time. He is the father of Zeus, Poseidon, Hades, Hera, Demeter, and Hestia. His tropes can be found [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].
[[/folder]]

[[folder:Leto]]
The Titaness daughter of Koios. One of Zeus' many lovers, with whom she had Apollo and Artemis.

* DisposableWoman: Koios implies that Zeus cast her out as soon as she gave birth to the twins. For some reason, she is in Tartarus as of ''The House of Hades'', though she eventually does manage to get out.
* GoodParents: Compared to [[AbusiveParents Zeus]], Apollo remembers her fondly.

[[folder:Metis]]
An Oceanid and the Titaness of deep thought. She was a lover of Zeus, with whom she had Athena.
----
* PsychicStatic: Zeus first married her, Titan of deep thought... and then swallowed her because he feared their children would overthrow him. Metis eventually dissolved into pure, occasionally annoying thoughts in Zeus' mind.

[[folder:Mnemosyne]]
The Titaness of memory.
----
* PhotographicMemory: She remembers ''everything''.

[[folder:Oceanus]]
The Titan of the sea, father of the Oceanid nymphs. His tropes can be found [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].

[[folder:Phoebe]]
The Titaness of foresight, wife of Koios, and grandmother of Apollo and Artemis.
----
* FortuneTeller: Percy describes her rather like one.
* ThePollyanna: Name means "Bright" which was how she tried to see the world.

[[folder:Prometheus]]
The Titan son of Iapetus who can predict the future. His tropes can be found [[Characters/TheCampHalfBloodSeriesForcesOfKronos here]].

[[folder:Rhea]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/rhea.jpg]]

The Mother Goddess, Rhea is the Titaness wife of Kronos and the mother of the elder four of the Olympians: Zeus, Hera, Poseidon, and Demeter, plus Hades and Hestia. She presides over motherhood as well as an oracle.

* AnachronismStew: More so than most of the other gods, Rhea seems to confuse different time periods, insisting Music/JimiHendrix attended the Seneca Falls convention with her.
* AscendedExtra: Rhea is mentioned as far back as the first book of the first series, ''The Lightning Thief'', though it was during an insult battle between Zeus and Poseidon. She gains far, far more prominence in ''The Hidden Oracle''.
* BeingGoodSucks: In ''Greek Gods'', Percy uses language similar to describing his own mother, in that Rhea had the nicest sweetest personality of out of the Titans, which meant she got the worst luck, such as having Kronos fall for her and having him swallow her children.
* HotGod: Percy describes her as this.
* NewAgeRetroHippie: Rhea's vernacular and fashion take cues from hippies, highlighting her rejection of Titan culture.
-->'''Rhea:''' The Man, man. Big Brother. The suits. The imperators.
* SophisticatedAsHell: Rhea's ominous warnings about the rise of the Triumvirate is mixed in casual slang from the sixties.
* TimeAbyss: Rhea's creation, the Groves of Dodona, was ancient even before the birth of Olympus, and she was alive even before that.
* VerbalTic: She punctuates many of her sentences with "Man", man.

[[folder:Tethys]]
The Titaness of rivers and wife of Oceanus, with whom she had the Oceanids.

* BirdsOfAFeather: She (rivers and streams) marries Oceanus (the ocean). "Hey you like water? I like water too! We should totally go out!"
* HappilyMarried: Her marriage to Oceanus. Hera tried to model her own marriage with Zeus after it, with considerably less success.

[[folder:Theia]]
The Titan of gems and jewels, wife of Hyperion, and mother of Helios.

* AttentionDeficitOohShiny: Percy thinks this is why she married Hyperion.
* TheDitz: Theia is... not too bright. Which is ironic considering she is the Titan of bright and shiny things.

!!Anemoi
[[folder:Aeolus]]
King of the winds, weatherman of Olympus.

* AscendedExtra: Was mentioned in ''The Last Olympian'' as the one defending the skies of Olympus.
* BewareTheSillyOnes: He's clearly missing quite a few screws, but that doesn't make him any less dangerous when push comes to shove.
* BlowYouAway: He's the most powerful wind god, and as such has domain over winds.
* {{Cloudcuckoolander}}: Being the weatherman of Olympus 24 hours a day will do that to you.
%%PointyHairedBoss
* UncannyValleyMakeup: He was described by Jason as a microwaved Ken doll.
* UnwittingPawn: To [[spoiler:Khione.]]

[[folder:Boreas/Aquilon]]
The North Wind.

* AffablyEvil: Definitely not the most antagonistic of the gods, but there's a clear undercurrent of cruel excitement in his discourse with Piper and Jason.
* ArchEnemy: To Notus.
* BackForTheFinale: [[spoiler:Per tradition, appears as one of the winds pulling Zeus's chariot in the finale.]]
* FaceHeelTurn:[[spoiler:Between appearances, Khione seems to have turned him to Gaia's side. Though this could just be her manipulating his fragile state of mind and body, as he's back on the gods' side by the finale.]]
* FrenchJerk: Of the French-Canadian variety, actually.
* AnIcePerson: Because he lives in Canada, he is far colder.
* UnwittingPawn: To [[spoiler:Khione.]]

[[folder:Eurus/Vulturnus]]
The East Wind.

[[folder:Notus/Auster]]
The South Wind.

* ArchEnemy: To Boreas.
* BackForTheFinale: [[spoiler:Cameos while pulling Zeus's chariot in ''The Blood of Olympus.'']]
* BrickJoke: During Boreas' rant about Notus in the first book, he makes an offhand mention of his holiday retreat in Cancún. When Notus makes his appearance in ''The House of Hades'', he too says that he has a lovely place in Cancún during the off-season.
%%[[ChekhovsGunman Chekhov's Gunman]]
* EmpathicShapeshifter: While talking with Jason, his form switches repeatedly between his two identities, mirroring [[spoiler:[[TwoRoadsBeforeYou Jason's confusion about whether he belongs with the Greeks or the Romans]]. When he throws his lot in with the Greeks, Notus's form solidifies for good.]]
* HotBlooded: Notus.
* TwoRoadsBeforeYou: Auster hates indecisiveness, and insists that he won't help Jason until he decides [[spoiler:between Greek or Roman.]]
* RedOniBlueOni: The Greek and Roman facets of his identity, respectively. Notus is thunderous and ill-tempered, whereas Auster is sluggish and lazy.
* SmallRoleBigImpact: At least as far as Jason is concerned, he's the one who solidifies Jason's decision to [[spoiler:go Greek]].

[[folder:Zephyros/Favionus]]
The West Wind, a servant of Cupid.

* BackForTheFinale: [[spoiler:Pulls Zeus's chariot in ''The Blood of Olympus.'']]
* CrazyJealousGuy: Murdered the guy he was in love with out of jealously.
* IfICantHaveYou: Was in love with [[PrettyBoy Hyacinthus]] and was jealous of the god Apollo's closeness to him, so when Apollo and Hyacinthus were playing a game Zephyros arranged for the disc to strike Hyacinthus. He doesn't seem too hung up about it, though.
* MysteriousStranger: With a bit of TheWatcher, he says that he's been watching Nico for years, knowing that one day he'd have to return to Split and face Cupid.
* WingedHumanoid: His preferred form has two large wings.
* {{Yandere}}: He murdered his crush because the crush was in a relationship with Apollo.

!!Specific Locations
[[folder:Achelous]]
Once god of the biggest river in Greece; currently stuck on Hercules' island as a punishment (whether it's for him or Hercules isn't clear).

* AbhorrentAdmirer: Seems to have been one for Deianara. It's never occurred to him that she didn't want to marry a bull with a human head who lives in a river.
* AntiVillain: Tries to drown Jason and Piper, but is really kind of pitiable and, to be fair, they were trying to take his other horn.
* ButtMonkey: Lost his wife to Hercules (see AbhorrentAdmirer), lost his horn (forever keeping his head off balance) and is now trapped on an island with Hercules, who hates him.
* MakingASplash: You come to expect this from a river god.
* MatterReplicator: His horns become cornucopias after being severed, at which point they shoot out food.
* MixAndMatchCritters: Human head, body of a bull.

[[folder:East River]]
God of the East River in New York.

* BrokenBridge: Once Percy pays him off he serves as one to Kronos by sinking his ships.
* GlowingEyesOfDoom: His eyes glow radioactive green.
* MonstrousSeal: He looks like a combination of a seal and a wolf.
* NoNameGiven: No name beyond the name of his river.
* SitcomArchnemesis: With Hudson River.

[[folder:Hudson River]]
God of the Hudson River in New York.

* BrokenBridge: Once Percy pays him off he serves as one to Kronos by sinking his ships.
* JerkassHasAPoint: He's rude and hostile, but he isn't wrong about demigods seeking the blessing of Achilles in the hopes that it'll solve their problems, just like he isn't wrong about how it never works.
* NoNameGiven: No name beyond the name of his river.
* SitcomArchnemesis: With East River.

[[folder:Tiberinus and Rhea Silvia]]
Rhea Silvia is the mother of the legendary twins, Romulus and Remus. Her sons were set adrift on the Tiber river. Its god, Tiberinus, saved the twins, who would go on to found Rome, and ended up with her.

* CelebrityResemblance: They look and act a lot like Gregory Peck and Audrey Hepburn off the set of ''Film/RomanHoliday''.
* SickeninglySweethearts: They act giddy and in-love.
%%ThinkNothingOfIt

* CanadaEh: He and his family live in Quebec, Canada.

* AdaptationalBadass: This version of Cupid isn't the cherubic winged baby that is normally portrayed. This guy gives Nico and Jason a run for their money [[spoiler: and manages to drag out Nico's suppressed feelings about Percy.]]

* CruelToBeKind: [[spoiler: After forcing Nico out of the closet, Cupid drops his harshness and admits with an air of sympathy that love often hurts, before giving him the scepter. He went about it brutally, but he seems to just want to help him finally be honest with himself.]]

* SilentAntagonist: Justified, since he's literally the god of silence. He also generates a bubble of absolute soundlessness around himself. The Triumvirate use magic to amplify this effect to block demigodly communications.

* BerserkButton: The very mention of Hera will piss him off. [[spoiler: He was nice and friendly to his half-brother Jason, hating to give hard quests since he was once a demigod...right up until he mentioned Hera's name. Then he gave them a really hard one and threatened to kill everyone on the Argo II.]]

* GodIsDead: Claimed many centuries ago, though the satyrs don't believe it. [[spoiler: Becomes true as of ''Battle of the Labyrinth''.]]

* PassingTheTorch: [[spoiler: He passes his role on to every mortal, satyr, and nature spirit in the world.]]

* UsedToBeASweetKid: Before he ceased to exist, anyway. Apollo implies that he was an all-around good guy, being one of the few male Titans who sided with the Olympians during the Titanomachy. Now, he is so much filled with anger that the first thing he says to Apollo when the two meet after his cessation is [[spoiler: to kill his granddaughter.]]

* BackForTheFinale: [[spoiler: Per tradition, appears as one of the winds pulling Zeus's chariot in the finale.]]

* FaceHeelTurn:[[spoiler: Between appearances, Khione seems to have turned him to Gaia's side. Though this could just be her manipulating his fragile state of mind and body, as he's back on the gods's side by the finale.]]

* TheCameo: His only appearance is [[spoiler: pulling Zeus's chariot in ''Blood of Olympus'']].

* BackForTheFinale: [[spoiler: Cameos while pulling Zeus's chariot in ''The Blood of Olympus.'']]

* SmallRoleBigImpact: At least as far as Jason is concerned, he's the one who solidifies Jason's decision to [[spoiler: go Greek]].

* BackForTheFinale: [[spoiler: Pulls Zeus's chariot in ''The Blood of Olympus.'']]

** A bit less so in her second appearance in ''The Chalice of the Gods"; while she is still largely friendly and ultimately helps the heroes out, she does make Percy undergo a somewhat-dangerous quest for her in exchange for her aid on the quest he was ''already'' undertaking (and when he succeeds, her happiness is directed more at her symbol of office that Percy cleaned and less at Percy for actually cleaning it). Percy even observes when on the way to meet with her that even the nicer gods can be fickle, and having had ''one'' relatively positive interaction is no guarantee for the future.

* YourCheatingHeart: The myths focus on his unrequired love for Hyacinthus, but forget to mention that Zephyrus is married. First to Chloris, a nymph turned goddess of flowers and then to Iris, the goddess of the Rainbow.

[[folder:Zephyrus]]
The god of the west wind and spring.

* AbhorentAdmirer: Was one to the Spartan Prince Hyacinthus.
* CrazyJealousGuy: Murdered the guy he was in love with out of jealously.
* {{Yandere}}: He murdered his crush because the crush was in a relationship with Apollo.

!!The Titans
* Note: Since an exact definition is very hazy, only the first and second generations of Titans are listed here (aside from the Olympians).
[[folder:In general]]
A series of deities who preceded the Olympians as rulers of the universe. The eldest of the [[Characters/ClassicalMythologyTitans Titans]] are children of Gaea, the primordial goddess of the earth, and Ouranos, the primordial god of the sky. Their domination ended when the Olympians overthrew their king, Kronos, and exiled him to Tartarus. The majority of the male Titans supported Kronos and were therefore exiled with him, while others supported the Olympians or remained neutral and as a result were allowed to live as minor gods. Other than the Olympians, many other gods have some amount of Titan ancestry.

* {{Bishonen}}: He's described as being long haired and beautiful.

* WickedStepmother: To Nico with whom she has a very strained relationship. She apparently turned him into a dandelion at one point.
** She seems to have moved past this by ''The Sun and The Star'' where she not only admits to Will that she didn't treat Nico right but goes out of her way to give Will advice about Nico and how to make their relationship work.
