What Happened To Everyone Who Became Iron Fist?

10. Quan Yaozu

No better place to begin than at the beginning. The VERY beginning, at that, with the very first Iron Fist known as Quan Yaozu.

We don't know that much about him, since he exists purely as mythology in the world of Iron Fist. It isn't like they gave him his own entire series (maybe if Iron Fist was actually a halfway successful property financially speaking, but alas).

What we do know is that he was one of, if not the earliest holders of the mantle, given to him by the elders of K'un-Lun to protect it and the other Seven Capital Cities of Heaven from a recently discovered, brutally hellish, eighth city.

When the time came to seal off the eighth city forever, Quan elected to stay on the other side to make sure it closed properly, condemning himself to death at the hands of the city of very pissed off demons.
