To Loveable Cats: BossdaPrometheuus is on the right track, Not trying to be rude or anything.

A villain is someone who does bad things as you got right, however an antagonist is a character who has opposing actions to the protagonist, and the protagonist is the character who tells the story, so therefore Mario cant be an antagonist in the episodes.
