The God-Emperor of Mankind

The God-Emperor of Mankind is the figurehead ruler of the Imperium in the Warhammer 40K universe. He used to be pretty badass, but following a couple of slight errors in judgement ended up in a coma attached to the Golden Throne, the only thing keeping him alive. There are a variety of theories on whether or not this is a good thing, but it is generally accepted that the absence of the Emperor's proper guidance is what has turned the Imperium into the hellish mess that it is. There are also a variety of theories on what circumstances might cause him re-awaken, which may or may not include Loli Daemonettes.

He is sometimes referred to as the Empra or Emprah, a joke derived from the voice acting in the Dawn of War games.
