Mario
Mario is Nintendo's mascot (the face of the company). Mario's rival was Sega's mascot, Sonic the Hedgehog. Sonic the Hedgehog first appeared in 1991. At first, Sega and Nintendo competed with each other. But then, in Sonic Adventure 2: Battle, Sega made a game for a Nintendo video game console. Mario and Sonic appeared together in a sports game, Mario & Sonic at the Olympic Games, and again in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS and Wii U, and Super Smash Bros. Ultimate.
