Sonic the Hedgehog

Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ Sonikku za Hejjihoggu?) is the titular main protagonist of the Sonic the Hedgehog game franchise, and the mascot of Sega. He was first introduced by Sega in the game Sonic the Hedgehog to combat Nintendo's mascot, Mario. He is often thought of as Mario's unofficial rival, although they have appeared in games together. He makes his first Smash appearance in Super Smash Bros. Brawl, as the second third-party character in Super Smash Bros. after Solid Snake but before Mega Man, Pac-Man, Ryu, Cloud, and Bayonetta. He also returns as a veteran in Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate.
