Sonic for sure! I mean he can roll into a ball and blast through anything in his path. How awesome is that?! ;D

I have to say Sonic has more style. Mario is a little gay with Luigi and his high-pitched cries for joy.

I like how sonic gets pissed at you when you stop playing.

Im talking about the Sega Genesis sonic. The only Sonic. The true sonic.

Sonic is sleek, speedy, and polished. Mario is big, fat, and klutzy. He's also pretty gay with Luigi. But Sonic was way better when he was owned by old school Sega, instead of new and improved Nintendo.

Sonic rules!!!!! I grew up with him! I've played Sonic 1, Sonic 2, Sonic 3, Sonic and Knuckles, Sonic 3D Blast, basically every Sonic the Hedgehog game you could imagine! I love the show Sonic X. Just look at my username and pic!!!

Sonic rules!!! Mario sucks!!!

I THINK SONIC BECAUSE HE HAS BETTER GAMES THAN MARIO MARIO SUCKS DICK SONIC ROCKS AND MOST OF ALL I PLAYED EVERY SONIC GAME IN THE ENTIRE WORLD EXCEPT SONIC XTREME AND SONIC DS SO SONIC 100%

Sonic. The games are both fun... but Sonic is waaayyy more fun.

Sonic i way better than mario well evne though the old school game were better then the new ones well Sonic STILL KICKS ASS WETHER HE HAS BAD GAMES OR NOT!!!!!!!!!!!

Oh btw Mario only saves his beloved Princess Peach wihtout even give a shit about whats going on about the world .Well Sonic has to give pretty much give up all his time saving the world fighting Dr.Eggman.IM defenetly On SONICS SIDE!!!!!!!!!!!!!!!!

Ablitys

Sonic:Faster Than Sound/Faster than light(when super sonic)which i heard.

Spin attacks

Athleticism

Chaos control(in SA2B)

Hyper Sonic

And Lotsa other crazy moves that are awsome!

I like the both of them ,but i rather sonic than mario imean all mario does is save peach peach just keep getting stolen by bowser over and over what a slut. bowser had it with peach to get bowser jr and she still likes mario thats why she's a slut

Sonic Rocks!!! I would rather support a cool blue hedgehog that has great speed and severe coolness instead of a fat plumber. Sonic games have more action and in Mario games its pretty much the same story all the time. If Sonic and Mario were fighting, Sonic would win hands down. Mario is fat and all he does is just stomp on his foes. Maybe Mario should work out so he could lose some weight. And he could learn how to fight better. SONIC U ROCK!!!!! YOU'RE THE BEST HEDGEHOG EVER!!!!!!

Sonic Rocks! Mario should work out more and lose some weight. Sonic would beat the heck out of mario

Mario FTW! He can jump extremely high and stomp on enemies! Plus he can throw fire balls at his opponents! how awesome is that? xD

Mario is better because he has more games after him and he is older then sonic with more experience

he is whey more fun than sonic

Mario is a fat plumber who should absolutely no place in the gaming world. Huh. It's weird because in the current standings, Mario has his foot on Sonic's writhing head. The true champion of games almost every single one of his adventures are an amazing playthrough. The same cannot be said for Sonic. Sonic uses cheap gimmicks and executes them poorly.

Don't be retarded. Mario wins.
