2) Bowser
I know what you’re thinking. How can Bowser be an antihero when he’s the main antagonist in the majority of Mario games? Well, things are a little bit different in Mario RPGs, where Bowser pretty much always teams up with heroes to fight the bigger evil. On top of that, he’s depicted as a more comedic character. Remember how he kissed Mario and then later in another game Mario got inside of him? Good times.
Good call with Corobo. Don’t forget that he would decide willy-nilly who had to get married and have kids.
No Pokey from EarthBound? :(
