Mario. Why? Because all Sonic does is run around on meth to destroy things. Does Sonic have HELPFUL friends? No, their all pussies and that flying one looks like something a flying koopa would eat.. Does Sonic have WORTHY villians? No, it's a fat dude with defective projects. What's Sonic's extra power ups? Turning piss yellow and going super faster which seems like the same thing. What about Sonic: Unleashed? Please, really? Mario could transform and use ANYTHING! Hell, even Mario Sunshine with that water spraying thing could defeat that thing by making it slip. I'm just sayin', Sonic was only developed for running and collecting coins. Don't get me wrong, even the original characters like R.O.B (He was in an old stacking game) didn't look as fun as Mario either. Mario in the original was addictive, obstacles we're endless and then Super Mario Brothers 3 had multiplayer which improved it's fame. Which proves his friends are helpful too because at least they go on to help defeat Bowser. Another thing is Bowser is some huge turtle thing but it seems Nintendo got creative and made it a Dragon. Better than that fat dude because he's more intelligent to have other powerful henchman to drive Mario to search more and more castles. That is all. Mario, everyone.
Mario. If Sonic ran off, as is suggested by "Mario would never catch him", then Mario would win by default. Sonic isn't faster than Mario in a battle situation, only when moving long distance. Plus, Mario could become Mega Mario, Fire Mario, or find a star, and whoops, game over for Sonic. Sonic can... um... curl up into a ball. Mario's clearly a star jumper, and would outmanuver Sonic in a battle situation. If we're using Super Mario Advance rules, then Princess Peach could whup Sonic. If we're playing New Super Mario Bros rules, then, two or three ground pounds would see Sonic off. Come on, if Mario can get Bowser every time with his shell and spikes, then Sonic's a pushover by comparison.
Water-jug well if thats the case then i daont think neither of them should win cuz they just might be there own asses
Hmmmmmmm... I VOTE [the following answer could not be shown due to lack of intellingence and big tummy-aches]
mario would rape sonic with his fire balls and his awsome mushrooms watch out sonic hes goin for ya mum
I believe it would be a tough battle. Both Mario and Sonic are just plan veterans when it comes to fighting. I believe and support Sonic however and think in the end Sonic`s overwhelming speed would get the job done.
Sonic, obviously. Both jump on peoples' heads to kill them, so my bet is on the one who has spikes growing out of his head.
