Mario and Sonic are not rivals. If you're thinking of Mario and Sonic at the Olimpic Games, yes and no. In virtual and real olimpic games you compete with each other. That does not make them rivals. If you saw a video of Mario and Sonic fighting, it is not owned by by Nintendo or Sega. (Except maybe a demo video or trailer of Super Smash Bros. Brawl, but that still doesn't make them rivals.) If there is a game where Mario and Sonic are rivals that I don't know about, reply.
