He only started a fight with Otto when Otto was gonna steal the helmet, during the surgery, he kept being annoying, but didn't interfere.
Anyways, there's also one weird moment from Superior#2, where Peter doesn't want Otto to break up with MJ:
And it's weird because, in the same fucking issue, he was shown disgust whenever something was going on between MJ and Otto:
Makes no sense, he should be celebrating that Otto broke up with MJ lol.
Also fuck, Ghost Peter is annoying, if I ever read Superior in its entirety, I'll probably be kinda happy when he gets "killed", will be one less annoying thing to put up with lol.
