Is sonic in super smash brothers melee? My friend said that sonic was in the game, and I also saw that mentioned on a website. Thanks.
No, neither Sonic nor Tails are in Super Smash Bros Melee. The total number of playable characters in SSBM is twenty-five, and none of them belong to SEGA. One magazine (EGM, I believe) published this as an April Fools Day joke.
