Triton (voiced by Chris Elliott) is the son of Poseidon and Amphitrite. He's also a sea prince who wants to go to Prometheus Academy with Hercules. It turns out Triton is somewhat of a nerd, wanting to be like his cousin Hercules; he has considerable acrobatic skills but terrible balance and timing, much like Hercules himself. He also has an older brother named Otis who goes to the Trojan academy.
Like his parents, Triton can breath underwater. He can also communicate with sea creatures like his father (at least dolphins, who according to him never shut up and mostly talk about themselves). He can also contol the trident to a certain extent (since he accidentally let a sea monster loose).
