Nokturnus

Nokturnus was a superboss found in Dragon Quest VI that is the most powerful character in the franchise. He is a diety that wants everything to be destroyed there to be only a void of nothingness, but he is not neccesarily outright evil, even aiding the heroes at one point.

History
Nokturnus was a god who was summoned by people from a kingdom known as Graceskull, they were trying to stop this being known as Mortamor who was destroying the entire world. He would have done the job, but he was offended when he saw the kingdom gave him offerings like spider soup. So he cursed the entire kingdom into flames. He is not seen again until the end of the game/

If you beat the game, he will appear as a bonus boss. If you beat him in under 20 rounds, he will fight Mortamor for you in an absolutely one-sided stomp.
