The Shredder is a powerful combatant and his thunder sword makes him a menace in close combat as well. That being said, Blasterman has the edge here. His super armor will protect him against the Shredder’s attacks. The Shredder will be able to dodge Blasterman’s attacks for quite a while, but eventually he will falter and be defeated. The Shredder just can’t pierce this kind of defense! Blasterman wins.
