Triton (Winx Club)

Tritons are magical sea creatures who are the male counterparts of mermaids and who come from the home world of Andros, with the upper half of a human and the lower part of a fish, and live underwater.

Individuals
The only Tritons known so far are Neptune, the King of the Seas of Andros, Nereus, the heir to the throne, and Tritannus, the son of Neptune and brother of Nereus, who was turned into a monster by pollution due to an oil spill on Earth, which came through a portal on Earth's oceans. The Winx will have to go on a quest to find the ancient Sirenix power to fight him because their Believix powers are too weak to fight Tritannus underwater. As it's been stated that Tritannus loses his power when his trident is destroyed, the Tritons' powers may be contained on their weapons, thus leading them to lose their powers if their weapons are destroyed.

Biology
They are humanoid in appearance, except for the fish tail in place of legs. They also seem to have strange sexual dimorphism in their species ( that is assuming they're the same species as the mermaids, which they most likely are), because unlike the females who possess fairy - like wings, the males appear to have a single fin found over the backbone.

Mutants
After Tritannus absorbs the toxic power, he turned into a horrible monster and turns the triton guardians into monsters. The same thing happened to mermaids. Other things coming soon...

Culture and society
The Triton, Neptune rules all of Andros under the Sea, with his Queen being the Mermaid, Ligea and their children are the Princess Tressa and the twin princes Nereus and Tritannus. Neptune is the brother of King Teredor and Queen Niobe and the uncle of Aisha. In Season 5, Neptune named Nereus as his heir to the throne, making Tritannus jealous.
