Arqum, have you ever heard about alternative universes? This series are not based on the real sonic story, but it is as i said: Alternative Universe. In this universe, Sonic doesn't know who is Rouge and Chaotix (as you could see in the previous episode), Shadow and Silvers are the dragons, (lol) and all the Megaman characters are some kind of the world protectors. Ok, that should be it. I hope you can understand it better.
