Triton

Tritanni is the son of Tritannus in Little Winx. He is very mean, selfish, and only cares about glory/wealth. In Season 5, the Little Winx go on an ocean-filled quest to stop Triton from fulfilling his father's request: To be the new emperor and do evil.

Tritanni is very persistent on his goals and will stop at nothing to make sure they are completed.
