Mashed sonic

As of now, not much is known about Sonic's true character. From what is seen in his debut episodes, he appears to have a generally calm disposition, speaking in a polite tone when addressing Amy and generally serves as a contrast to Tails' more unstable personality. Despite this however, Sonic is implied to be just as insane as his partner, and is simply better at hiding it. This is seen by the fact that not only does he have the same desire to destroy all universes with a "fake" Sonic in them, but also having a hint of possessiveness to him as well, mentioning to Amy that he had already lost her once and that he wasn't going to let her go again.

To emphasize this point more, Tails reveals that he had been the one to send him to Amy's world in the first place, while he's not explicitly implied to have instructed the fox to turn Amy into the monster she became, he was nevertheless proud of the result, saying that she was "The Amy of Amys". He's also the one to convince Amy to infiltrate Knuckles' world and corrupt him into becoming a kaiju before eventually destroying it, only lending more credence to the idea that despite how jovial he may act, he's just as crazy and obsessed as Tails is.

He's also shown to be manipulative, roping Amy into his any Tails' scheme of destroying all realities with a "fake" Sonic in them and helping put together a corrupted version of all of his friends by stating that the fake Sonics were "deceiving them" and "denying them their truth".

Which sonic would fall and act like his evil counterpart Scourge from the Archie comics reference all it takes it one bad day and you be just like me which scourge words did made him just like him all together.
