Suggested by Destroyer Vengeance has energy blasts and some super strength. That makes him pretty tough to deal with but Swordman has speed at his disposal and those powerful shockwaves. I don’t expect Vengeance would be able to survive too many direct hits and he would have a hard time dodging. I can see this being a fairly close fight but at the same time it’s one where I am pretty confident on the victor. Swordman’s attacks are just well suited to blocking fire and keeping Vengeance away. Swordman wins.
