I'm About to Be Defeated by a Hero With Nothing Better to Do

I am the Demon King. When most people think of a Demon King, they imagine someone who commands all demons, stands above everyone, and is insanely powerful, with a goal of spreading fear and darkness to every corner of the world. But that's not actually what I'm like. First, I'm not the strongest fighter among the demons. Second, I don't have any great talent for military leadership. Third, I have no ambition to conquer the world. The only reason I got this throne is that I'm so handsome. Everyone says I look like Gul'dan, so the Demon King is really just the demon race's designated eye candy. The important thing is... who exactly is Gul'dan?
