They first met at least ten years prior to the comics. They were imprisoned by Robotnik Prime (Dr. Julian Robotnik) and became fast friends. On the way to the prison camp, they also met Sonic. When they escaped, Ray grabbed a Power Gem but was zapped in the back. Ten years later (Knuckles the Echidna Issue 27) Ray came back but has not aged a day. Possibly from what happened ten years and was in a dimension of his own. Now he's traveling with Mighty to help the armadillo find his long lost sister.
