Like his father, Triton carries a trident. However, Triton's special attribute was 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, who imagined it to be the roar of a mighty wild beast. Triton dwelt with his parents in a golden palace in the depths of the sea.
Triton was the father of Pallas and foster parent to the goddess Athena. Pallas was accidentally killed by Athena during a sparring match between the two goddesses. Triton is also sometimes cited as the father of Scylla by Lamia. Triton might be multiplied into a host of Tritones, daimones of the sea.
Triton was adopted by the Romans as the son of Neptune and Salacia. In the Aeneid, Misenus, the trumpeter of Aeneas, challenged Triton to a contest of trumpeting. 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. It is also possible that he is jealous of Percy, as his father declared that Percy was his favorite son instead of him, despite being only a demigod. However, he shows respect to Tyson by nodding respectively. He is seen only briefly however, so his actual attitude in general is unknown. He also seems to be proud of being Poseidon's son, saying "Your son and heir," after Poseidon introduces them, saying "Yes, well ... and this is my son Triton. Er, my other son."
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 also described as a merman with two fish tails instead of one, but he looked young, had green skin and black hair tied in a ponytail, and he wore armor studded with pearls.
As the son of Poseidon and Amphitrite as well as an actual embodiment of the sea itself, Triton is extremely powerful, much more than a demigod, but less than an Olympian. He is considered a minor god.
He possesses the standard powers of a god.
- Hydrokinesis: Triton has the ability to create, manipulate, and control water to his will. He has the same hydrokinetic powers as Percy's, only to a more advanced level.
- Aerokinesis: Triton can manipulate the sea breezes.
- Fear Inducement: Triton can invoke fear in others, an ability which he usually channels through his conch shell, though he can do so without it. He once used it to frighten off the Giants when they attempted to invade his father's kingdom, driving them into hiding among the mountains, and almost incapacitating their king, Porphyrion, in the process.
- Shapeshifting: Triton can alter his physical form to resemble that of any sea creature he wishes.
- Telepathic Communication: Triton is able to communicate telepathically with equestrians and sea creatures.
- Superhuman Strength: Triton possesses enhanced strength.
- Superhuman Speed: Triton can move at superhuman speeds.
- Flight: As a messenger god, Triton has the power of flight.
- 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.
- Triton was called The Son of Neptune by the Romans.
- 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.
