Aile Graff

Aile Graff is very, very tired.

Originally just an average dude, he got kidnapped alongside his friend Brooke to be used as a test subject for roboticization. In a stroke of luck, there was a blackout that allowed him to escape, but not without being partially roboticized and stranded far away from home. His main mission was to find his missing friend, and hopefully reverse what happened to him so he could go back to a normal life. Only one of those things happened.

There's a silver lining, though: his super strength makes him a powerful member of Team Comeback, and he's now friends with a bunch of cool people, including Vent and Tails.
