From Multiversal Omnipedia
Lieutenant Granitor was a large, gray Stone Warrior who was with General Traag while he was chasing three Neutinos. He and his superior were accidentally brought to Earth when the Shredder opened a portal to Dimension X. Granitor was reunited with Krang and he and Traag served him on Earth until the Teenage Mutant Ninja Turtles knocked the pair back through the portal to Dimension X.
