Suggested by Anonymous Tetsuo Shima is definitely quite powerful. He was able to fly into space in an instant and he caused an explosion that could wipe away a city. Guyver will have to be at the top of his game here. Tetsuo may actually have the edge against Guyver with speed, but his defense is considerably lower. I think Guyver can also take Tetsuo’s best shots long enough to dish out his own. Guyver will land the hits and Tetsuo’s fragile defense will be the end of him. Guyver wins.
