While researching alternate universes and how to travel to them, Greg discovered a way to travel to the Sonic universe. Naturally his curiosity outwayed any thought of danger that a transition like that could have on his body and created a device to create a portal to that universe. The moment his body entered that universe it began to change. He got shorter and cuter. His lab coat became bigger on him. There he was, on planet Mobius and meet a great friend and inventor rival in Miles Prowler, known as Tails. Greg frequently goes to planet Mobius to help Tails with his inventions and has a lot of fun.
