Hyper Sonic
Pit is a cheap character, but I think Sonic would win 55% of the time because of his speed.
Dark sonic would win period. Dark sonic can disintegrate anything he looks at. Sonic just turns super sonic and runs and were weolf form, but they are both still pretty good.
i think sonic would win but then again sub zero may freeze sonic but sonic can just turn super and kill subzero before he even seen it coming

In my opinion, Mario would win easily. In my opinion, yes. Sonic would win.

Its so obvious! Mario will leave Sonic lying on the ground,groaning.(Mario wins).
No weapons: Sonic speeds around Mario at 600 mph and smashes into him with spin dash, effectively cutting Mario in half. Sonic wins. Weapons: Mario uses a star to go invincible, Sonic uses the Chaos Emeralds to go super. Tie.
No, Sonic wasn't only created to rival mario, well, about 2 years before that. Sonic was created in his first game, just to destroy robots and collect Chaos Emeralds. Mario was created in his first game, just to kill Gombaas, Koopas and circle-headed gombaas. And defeat Bowser and rescue Princess Peach too.SEGA and Nintendo made 'Mario & Sonic at the Olympics' series together.Years before that, Sonic and Mario were mortal enimies, If Super Sonic competed Fire Mario for a battle, Super Sonic would easily win by jumping on Mario, burning Mario himself out.
werehog has physical attacks, but fire Mario has projectile attacks. hm, i don't know.
It's hard to say, it depends on who would participate, Sonic is most popular in the UK and Europe, whilst Mario is popular in the US and Japan. But since Mario has been around longer than Sonic, he may have a slight advantage.
Although this answer is completely opinionated, SONIC WOULD WIN FOR SURE!!!
