Thor is one, but I am not sure if Tony could take him in pure melee. Guts is extremely fast, and if shield strikes from Steve can rock Tony, Guts wacking him in the head with Dragon Slayer could very well ruin his day quite badly.

Tony at least has the benefit of being able to fight at long range without having to fear anything in Guts' arsenal. Just fly into the stratosphere and spam tank missiles and repulsar beams. Don't bother with a direct confrontation.
Edit: Oh nvm. Topic says Melee. Yeah, in that case, Tony would get clobbered.
Yeah, Guts is plenty fast, strong and tough enough to give Thor a decent scrap at close range. Thor would still win though.
I actually forgot what a monster Guts was until I recently got back into Berserk, after watching the, I suppose, kind of remake of the Golden Arc, which was converted into a film trilogy a few years ago. And then got into the latest anime and back into the manga again as well. Watching Guts casually hack half a dozen fully armored knights in half at a time, with individual sword strikes, never gets old lol.
What about Ronan maybe? Even though Drax was drunk, Ronan beat him badly. And showed a decent level of speed/reactions/spatial awareness, being able to even dodge blows that were coming from behind.
