Then there would be no reason for SEGA creating him in the first place.
Wario is too slow to keep up with Sonic. So Sonic would pawn him.
I think silver kills sonic:))
sonic the hedgehog is not slow he can go the speed of sound.
He maybe did but I know Sonic can use his special attack
No.
Sonic from Sonic X would ask who Sonic the freedom fighter was and then the freedom fighter said he was Sonic the Hedgehog and they would start a huge fight and in the end Sonic from Sonic X would win because Sonic Underground is dumber than Sonic X. well, for one, that cant happen because both tv shows were based on the same character, but with different meanings. my point of view is sonic underground sucks, and sonic x rocks! :D but that's just me. from mf842
The series would be ruined.
SEGA accidentilly made Sonic fast,not slow
Combustion and decombustion would be extremely slow
Sonic Rush happened in 2005.
Sonic Advance happened in 2001.
Sonic Unleashed happened in 360.
