Welp, here's a thread for those of us interested in sharing theories and headcanons. Please don't get into arguments, debates, sure, but don't be jerks during one. Because I'm in a bit of a rush, I'll post my up-to-date Sonic Timeline theory: And the timeline mentions a second Metal Sonic during Triple Trouble. That isn't a random addition, that Metal Sonic is damaged and refurbished by Robotnik with knowledge garnered during Generations, building the Metal Sonic seen in Sonic 3 and Knuckles from TT Metal Sonic's remains. Please, share your theories, I'd be interested to hear them all.
