Greg

 is an alien who participated in a tap-dance contest that Randy organised in 3013. He was the last contestant to be eliminated before the finals, losing to Bender and Tonya in week three. After seeing the finals, he watched the death and subsequent resurrection of Tonya, who won the contest, and patted Bender on the back for bringing Tonya back to life.
