What Happened To Everyone Who Became Iron Fist?
3. Power Fist
You knew this weirdo was gonna show up on this list somewhere, as he couldn't NOT be mentioned at least a little.
Exiles, aka "who needs you, internet, we'll make our OWN fanfiction, with blackjack and hookers!" introduced some of the wackiest stuff ever penned for the house of ideas, due to its multiverse-spanning premise. So in that regard, "what if Iron Fist and Luke Cage were the same guy?" seems almost tame compared to some of our main characters.
Power Fist, despite the above joke, is not ACTUALLY the two characters fused into one body. In actuality, this is just normal Luke Cage, with his usual origin, but with the twist that somewhere along the way he got the powers of the Iron Fist on top of the invulnerability and super strength that came with his default origin.
As you can imagine, this dude is not someone you wanna mess with. A shame we don't see that much of him outside of Exiles, and not even much in that book.
