Steel FistRenowned (?) Boxer! Doesn't back down from a fight, and will take down opponents with sheer force! Steel Fist joins the fight!
Maybe.
Based off: Hard Man
Battle Style: Steel Fist is a big boxer and is very used to the ring. As such, he knows how to hit like a truck. Some of his stronger attacks might require some wind up, but once the attack connects, there's gonna be a lot of pain on the enemy side. Due to structure and experience with a lot of fights, his defenses are rather high as well, letting him tank a lot of physical attacks.
The same can't be said for other attacks, where Steel Fist is a lot more vulnerable and can't tank nearly as well.
tl;dr: he punches a lot of things and it hurts, he can also take punches but not take missiles or fire or something. Is more about focusing on one target than groups.
Appearance: 
Seriously though. Steel Fist has quite a presence, donning blue armor (as one would expect given the origin) around a rather big body frame. Though below the waist the appearance changes to a lighter blue than that of his main body. He almost always wears a champions belt around his waist. His actual fists for their power, don't seem that impressive...until any sort of match where they morph into a more boxer glove shape. Woo.
Personality: For being a rather good boxer, Steel Fist doesn't really bring it up that much outside of the ring. He is more of the quiet type, and doesn't often respond to a situation unless provoked. Though he will almost never give up a fight and if challenged, nine times out of ten, he will quickly accept the battle. He lives for the fight, even if he doesn't show it nearly that much.
