Griffin is a super-villain and enemy to the fourth Flash, Bart Allen. He began as Allen's close friend and roommate when the two worked together at Keystone Motors, then received energy powers in an accident. The powers caused him to grow arrogantly self-centered while they aged his body much faster than usual. He turned evil and died shortly afterward. Griffin was created by Danny Bilson, Paul DeMeo, and Ken Lashley, first appearing in The Flash: The Fastest Man Alive #1. (2006)
