Suggested by Random Superman is a very powerful comic book character. He has juggled whole planets in the past and his speed isn’t bad either. Let’s be honest here, nobody goes into a fight with Superman and walks away unscathed. Well most don’t anyway, but Jiren would be able to. He just doesn’t get hurt very easily and he would be able to speedblitz Superman from all sides. That would be the end for the Man of Steel. Jiren wins.
