Suggested by Sonic Shuma Gorath is an interesting Marvel character. Technically he is one of the strongest to ever appear in the verse. He has a great arsenal of energy attacks and his sheer defense is impressive. Hellboy is more of a traditional fighter although we’ve seen him with mountain level feats. Hellboy’s strong, but I don’t believe his abilities are at quite a high enough level to do a whole lot against Shuma. Shuma Gorath would take whatever Hellboy dishes out and then some. Shuma Gorath wins.
