Widowmaker

If this guy wanted to wrestle aliens, would you tell him, 'No?' Didn't think so.

Origin
Imagine, for a second, that aliens were real and that they came to Earth. Not to be our friends, but to conquer it. Look around you…see any super heroes? Neither do I. Now, sure, we could throw the Armed Forces of the entire world at them (maybe, if all got along), but what if all it took was a group of men and women that could be passed off as super heroes? What if instead of cannon fodder and casualties, we told them that we had powerful men and women that could beat them in combat? Yep. We sent professional wrestlers to deal with them. Welcome to the GWP. Galaxy Wrestling Pro. A federation made up of humans and aliens alike.

'Maker is the most dominant force of nature the wrestling world has ever seen. He is unstoppable 1-on-1 (so you can imagine that it took a lot of trickery to beat him for the title). Neither heel nor face, the Widowmaker just is.
