Triton has long, wavy, orange hair, light green skin, and a blue tail. He wears a light brown vest and a blue headband on his head. He also wears a brown belt around his waist with a small pouch on his right side that has the letter "T" on it, which stands for his name. He wears a necklace with a blue crystal on it and a rope-like wristband. He also wears two pearl bracelets on his other wrist.
When Triton was a kid, his hair was short, he wore a white T-shirt, he wore the same belt like his Mom and Dad, had two golden clasps on his right arm that were like his Mom's, and strangely, he has the same voice now as he had as a teenager.
As a child, Triton showed interest in mortal affairs during his smiting lessons with King Neptune. He tells his father that he wants to play baseball (called the "ball and stick game" by Triton). His father then smites a single light post at the baseball field and sets it aflame. He tells his son that he could hit a home run and Triton leaves, as he wants to be alone. When he is grown up, his father finds him successfully making a cure for all mortal diseases. King Neptune destroys it and realizes Triton needs to learn to be the god he expects him to be. So, he locked his son in a cage in the Island in the Sky, where he will be, in his case, 10,000 years (although Triton's only been in the cage for about 1,000 years). When SpongeBob lets him out, he locked his father and everyone at the party in a cage as an act of revenge. Later, the two reconciled their differences with each other and hugged after Triton destroyed Bikini Bottom. The citizens put the blame upon SpongeBob and Patrick for the destruction that happened.
Triton is the (former) main antagonist in the episode. The Clash of Triton was based on him, and King Neptune regretting to lock him up. At the end of the episode, he finally reconciles with his father so he is no longer considered a villain.
Triton is the main antagonist of the game. He captures his family and others within the Krusty Krab. SpongeBob and Patrick try to stop him but they fail. However, they manage to acquire the tridents of King Neptune and Queen Amphitrite to gain god-like powers. The heroes must face off against Krabzilla and King Neptune's advisers (who Triton uses for his cause) to clear each area of Bikini Bottom (including Rock Bottom) which Triton has turned into a giant mountain called Mt.Triton. After clearing the areas, the heroes arrive at the Krusty Krab. Triton uses his god-like powers and his Krabby Patty minions to attack. However, SpongeBob and Patrick manage to defeat him and rescue his prisoners. He is later reunited with his father.
He appears on the cover along with many other villains.
Triton refers to baseball as the "ball and stick game."
Triton tends to say "man" in nearly every sentence. Sometimes, he would say "bogus" which might indicate that he has a stereotypical teenage attitude, explaining the behavior.
Triton is the messenger of the sea and the son of Poseidon in Greek mythology.
Triton and Neptune both have orange hair, but Triton's hair is more of an auburn orange, while Neptune's is a bright scarlet.
Allusion: Triton's interest in the mortal world is similar to Princess Ariel's fascination of the human world in The Little Mermaid. Also, both their fathers disapproved of their likings.
In addition, he is a redhead, similar to how his namesake counterpart in The Little Mermaid series had red hair in his youth.
Neptune says that Triton was to be locked in the cage for 10,000 years, when he just turned 5,000. He probably was exaggerating, and it might have been about 1,000 years Triton was locked in.
If one would look closely, the two hair locks that show on the outside of Triton's headband have different lengths in some scenes in "The Clash of Triton" (one shorter than the other); however, in most others, they're the same length.
Triton seems to have a strange habit of trimming his fingernails, probably because it was the only thing he could do when he was in the cage (he probably kept his nail clippers in the pouch attached to his belt, as seen where he ignored his father's plead to let everyone in the cage go).
In Serbia, Mermaid Man's name is Triton, so this character sparked some confusion.
Despite Triton's previous hatred towards his father, he also fears him (unless he is secured) because of his fear of the cage.
