Who do you think would win Rainbowdash or sonic?

Although This is your opinion I think sonic would win, I mean sure rainbow has the advantage butwith sonics incredible speed she would be able to touch him, also sonic can sorta fly since his spin dash attack from sonic X (u know when he goes into a ball and goes in the air and flies) he can sorta fly kind of so yeah sorry girls who watch my little pony but rainbow would SUCK against sonic! Isn't that right sonic fans!
