Dark Sunnycide X

"Kill you? ...Look, kid, this is how I function. If you want to live, I'll kill you. If you desperately want to die, I'll do everything I can to make sure you live. It's not your girl's fault her life came to its last chapter. Who was the one to just stand there? And not do anything due to his fear to risk his life for even those he loves?"

Summary
The Dark Sunnycide X is the main antagonist of Season 1 of Mario Adventures. He is a godlike version of Sunnycide, boss in Mario and Luigi: Partners in Time, accidentally resurrected by butterfly effects caused by Bowser's time traveling in an attempt to rid the timeline of Mario.

This version of Sunnycide has a black shell with white dots instead of pink with green, the ability of speech, a sadistic, psychopathic personality and massive bloodlust, immortality and a massive array of dark powers. His goal is to become powerful enough to channel the Zenith Star, an artefact that can give others the power to completely remake the reality. Along this way, Sunnycde goes on a killing spree through the world of Mario, killing even Bowser along the way, among others. While the heroes venture through many locations to perform a ritual to create a 1-Up Aura to resurrect all of the victims, Sunnycide simply resumes his murdering while hunting them down, taking more and more lives as time goes on.

Eventually, Sunnycide, in his search for the Zenith Star, comes across the god tiers of the Marioverse — Rosalina, Chakron, Queen Jaydes and the Star Spirits. He slaughters them all. He then finds out about the Shadow Queen and kills her as well to make sure the Zenith Star is his, then hunts down the other Marioverse villains and battles them as well, emerging victorious time and time again.

The heroes knew this couldn't go on any longer, and worked together with the remaining villains to defeat Sunnycide once and for all and finally end his ravage.
