Superman vs Onslaught

Description
DC vs Marvel, again. Will Superman overpower Onslaught, or will the Man of Steel have to behold his mighty hand?

Superman
''Superman: I feel like I live in a world made out of cardboard. Always taking constant care not to break something, to break someone. What we have here is a rare opportunity for me to cut loose and show you just how powerful I really am.''

Onslaught
''Onslaught: Free will is a privilege. Not a right.''
