Suggested by iKnowledge Grunbeld is a pretty big Berserk villain, but he isn’t quite ready to take down a powerhouse like Superman. Superman is still the strongest comic book character of all time and his stats are just off the charts. Grunbeld can turn into a giant monster but that would just seal his fate. In his mortal form he is also pretty quick and strong, but I can’t really say that I’m all that impressed with him. Superman will be able to take him down a few pegs with his superior speed. Superman wins.
