Triton

Triton is the main antagonist of the SpongeBob SquarePants episode The Clash of Triton, and he is the son of King Neptune I and Queen Amphitrite. In the episode, he was placed in a shrinking cage for a thousand years as a result of having a hard time coping with godhood, and upon being released by SpongeBob and Patrick, he realized his father was right as he ended up viewing mortals as 'lame' and wreaked havoc, convincing King Neptune he has accepted godhood and accepted him into the family again.

Biography
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.

Role in the series
Triton returns and gets another role in the Chronicles series, and one that holds true to the lies in the ads of his debut episode. Upon opening up to mortals again and falling in love with mortal women, and even rejecting his brides The Tritones, careful manipulation from his uncle Hades, his Villain League counterpart and Plankton, through the desperate girls gets him so amoral, he becomes an 'ascended god' and, unsure of what he wants, becomes a villain out to destroy mortal society, naming the Tritones as his henchwoman, along with his amoral titan ancestor Oceanus, his old pet Cetus, and Oceanus' many evil descendants in the form of Oceanids and Nereids (sea nymphs), to do it. Thus, SpongeBob, with the godly aid of Thetis, gets the godly power to stand up to Triton, and eventually get him to realize he is being used by his evil uncle to unleash his evil titan grandfather, Kronos.
