First fight, from Heroes for Hire v1 11
Second fight, H4H v1 19
I love Cat, but he's almost like a completely different person between their first and second fights, and Ostrander wrote both of them. I don't think I've ever seen him as cynically mercenary as he was in 19.
Either way, it's pretty impressive for Danny to beat him without the use of the IF, because Cat managed to fight Shang Chi to a draw on three occasions in the 1970's when he was virtually unbeatable, and I can't think of any particularly bad showings in his very limited number of appearances.
