The Mugwumpus

The Mugwumpus is a secondary antagonist in Super Smash Bros. Into the Void!.

Biography
The Mugwumpus was created by Turunga Tuwabee to attack the cast of Stannard Misadventures. While at first, his plan and powers were unknown, Lucario was able to magically and conveniently figure all of this out in mere seconds. Once he his plan was exposed, he was heroically murdered by Lucario, and became the a source of ridicule for an unspecified period of time.

Personality
He is evil, which means that he is not good.

Powers/Abilities
The Mugwumpus apparently has the power to give anything unsightly green lumps, causing whoever sees/has the lumps to hate everything. We never get to see any of this in action, so the audience has to take The Author's word for it.

Trivia

 * Similar to The Crinkler, his brief appearance and lack of contribution to the overall story have made many fans wonder why he was even included.
 * Of course, anyone who asks this question is an idiot bully.
