um i dont see any reason y mewtwo takes this 1. the devil has tk of his own hell devil jin (which is has only half devil) took out half a city blocc with his tk and didnt seem as if hes straining to do so 2. mewtwo is a psychic pokemon weak to dark attaccs i think the devil incarnate and a half demon would be pulling off some sort of dark attac either one could solo team 10/10
Mewtwo creates a protective sphere, this to shield him from Dante's bullets. He will then with plain thinking send both Devil and Dante flying in seperate directions and mentally abuse them.
Devil may so have taken out a city block, but Mewtwo almost destroyed the world with his telekinetical abilities (Would have if not he had invited the humans for a final stance). He can lift busses from miles away and that being trough mountain and forest. He has destroyed two massive facilities by just looking. One did he destroy with a thought and the second by looking around.
