I'd be a player character. I'd have astonishing adventures, wear outrageous outfits that clearly place form over function but still are somehow more powerful than the ones they replaces, die regularly but just come back from the dead with a bit of gear damage, grow in power exponentially to the point that it's really just silly, and have a kill count in the tens of thousands. Honestly I think the story of what would happen if there were player characters like the ones we play and all the mechanics etc were canon would be a very interesting one.
