Sonic because he was made first and Mario is trying to copy him... Sonic > Mario, in a lot of peoples minds.
Belive it or not, the first time Mario and Sonic appeared in the same Video game was Sega's Mario and Sonic at the Olympic Games made in 2007
Mario came first
Mario is older, Mario was made in 1981 and sonic made in 1991, I think it is very obvious, have you played that donkey kong game? that makes it obvious. look at how old it is! its was made in the 80's.
good question I think in the first sonic and mario game,or youtube
sure first was Mario and sonic at the olympic games then Mario and sonic at the olympic winter games then its Mario and sonic at the London 2012 olympic games
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.
No, the reason why is New super Mario bros is made my Nintendo(Mario makers) not SEGA(sonic makers)
Sega
Back in the days SEGA and Nintendo were like mortal enemies. But Sonic and Mario were concidered to be enemies. But know like in the 2006 and up, Nintendo and SEGA teamed up and that's how sonic came in Brawl and Mario and sonic at the olympic games was made. And that means Mario and Sonic are friends.
Mario has superior strength in comparison to Sonic however Sonic is faster than Mario.
I think the only one out so far is Mario & Sonic at the Winter Olympic Games.
