Iron Fist didn't really do much supernatural stuff. He was always "Focus your chi then do the mickey" and other stuff.
There were some supernatural elements, like ki blasts and ki weapons, but I don't think there was much about alternate dimensions and demons and stuff.

Then again, I mostly read him in Iron Fist and Luke Cage: Heroes for Hire, where he basically kicked the shit out of drug dealers and pimps, so I might not have read the right books
