|“||Hello, Perseus Jackson. Come to help at last?||”|
–Triton to his half-blood half-brother in, The Last Olympian.
Triton is the sea messenger god. His Roman counterpart is Triton.
Misenus, the trumpeter of Aeneas, challenged Triton to a contest of trumpeting. However, the god flung him into the sea for his arrogance.
Triton is somewhat cold and arrogant to Percy Jackson, talking down to him and acting as if his half-brother was lazy for not appearing sooner after Percy jumped off the now blown up Princess Andromeda. This is probably understandable, however, as Percy is the son of his father's affair with Sally Jackson, a mortal. Triton makes fun of Percy, smiling at one of his comments. However, Triton shows respect to Tyson by nodding respectively.
Percy mentions Triton when saying how sea gods are very possessive of their magic items, saying his immortal half-brother practically sleeps with his conch.
Like most gods, Triton seems to be proud and arrogant. He is jealous of Percy, his father's favourite son instead of him despite being only a demigod.
In Percy Jackson's Greek Gods, Triton was described to have the appearance of a merman with two fish tails instead of one.
In The Last Olympian, Triton was described as a merman with two fish tails instead of one. He looked young, had green skin and black hair tied in a ponytail, and wore armor studded with pearls.
- Hydrokinesis: As a sea god, Triton has absolute control and divine authority over water and the sea. He has the same hydrokinetic powers as Percy's, only to a more advanced level.
- Tidal Wave Manipulation: Triton has the ability to manipulate tidal waves, which he channeled through his conch shell. When he played it as a trumpet, the sea waves would either calm down or rise up in accordance to his will.
- Speed Swimming: As the Messenger God of the Sea, Triton has the ability to swim at incredible speeds as Hermes and Iris do in land and skies.
- Aerokinesis (limited): Triton has limited control over the air. He can manipulate the sea breezes.
- Aquatic Telepathy: Triton is able to communicate telepathically with equestrians and sea creatures.
- Superhuman Speed: Triton can move at superhuman speeds.
- Shapeshifting: As a god, Triton can alter his physical form. He can resemble any sea creature he wishes.
- War Trumpent: Triton's special attribute is a twisted conch shell, on which he blew like a trumpet to calm or raise the waves. Its sound was so terrible that when loudly blown, it put the giants to flight, as they imagined it to be the roar of a mighty wild beast.
- Trident: Like his father, Triton carries a trident.
- Triton might be multiplied into a host of Tritones, daimones of the sea.
- Triton, a moon of Neptune, is named after this deity.
- Triton's Trumpet or Triton Snail is the common name given to members of a genus of sea snail.
- In myths, Triton is sometimes cited as the father of Scylla by Lamia.
- The relationship between Triton and Percy may be seen as sibling rivalry, as they both attempt to out do each other to prove their worth to their father.
- Ironically, in the The Mark of Athena, Camp Fish-Blood (as Leo Valdez calls it) say they do not allow children of Poseidon, despite Triton being a son of Poseidon.
- According to Percy Jackson in The Ship of the Dead, all sea gods are vainer and more possessive than other deities where their magical items are concerned - Triton sleeps with his conch-shell trumpet.
