Momonga

I was thinking that it might be okay if Momonga and Dekatsuyo didn't switch bodies again. If they hadn't switched bodies, it probably wouldn't have been very fun. Thanks to the current 'fake Momonga' personality, he's quite popular. You need a villain for the story to progress, and even in the movie, although Momonga caused trouble, he ultimately carried the team. I think Momonga's charm is 99% his viciousness. Without Momonga, it wouldn't have been fun. Summary: Momonga's viciousness is the best.
