Suggested by iKnowledge Superman is the strongest comic book character of all time. His strength is transcendent and his speed is crazy. That being said, Yomi can more than hold his own against the Man of Steel. Superman will have a tough time keeping up with his efficient moves. Moreover, Yomi’s energy barrier will block Superman’s attacks. Yomi has earned his title of S Rank Demon and that makes him too much for Superman to handle. Superman just doesn’t have what it takes this time. Yomi wins.
