Well, kind of. He's mainly shown to be a serious villain, but does have some rare moments like this (such as, when Mario acts annoying on the Firestorm, Nul frustratedly says "Thanks a lot, dumbass. You reminded me why I want to destroy your miserabe planet!" and, when confronted with all of SMG4's allies in 'SMG4: Battle Of The Mushroom Kingdom', he says "My lord, I thought this would be a challenge!").
