The title says it all
What is your opinion on the Ebony Warrior and his origin?
Personally I believe he is the aspect of Reymon Ebonarm, the Yokudan God of War.
Chat it up.
But when you think about it, isn't every one of our characters and builds in Skyrim badass? He's meant to represent the stereotypical overpowered warrior we've all played, which means he's pretty much as tough as you can get. This is why I think he's just a man - a blank slate, like all of our characters were initially.
