Derf

Derf is a very powerful inter-dimensional entity that presides over all things pertaining to video games, technology, and the universal force of awesomeness. Though this is all that he is responsible for, he is still omnipotent and omniscient though usually lets its followers find their own way as long as they stay on the lighter side of morally gray. He speaks in 133t speak and internet slang, has many different personalities (one for each video game genre), and, if you do right by him in life, he will elevate you to the Emerald Arcade, where you will live among the most advanced technology, awesomest games, and a lot of other things. Hey I don't know it was a short conversation.

Dude 1: Man for a while there EA was pretty bad with their games.
Dude 2: I know I wonder why?
(burst of pixels, Derf appears)
Derf: I know I let them come under the influence of the Great Spectator for awhile.
Dude 1 & 2: Let us worship you!
