Suggested by Sonic Rodin is a pretty powerful fighter. He looked very impressive in the Bayonetta series and I haven’t seen anything from Bowser to suggest that he would be a match for such an opponent. Bowser’s strength is his biggest selling point and in that area he is already outmatched by Rodin. Even ignoring all of Rodin’s other abilities that is already the end of the match. I like Bowser but he is just outclassed in every possible way for this round. Rodin wins.
