SSB fighters outside SSB

[Psychospacecow]

Link, Snake, Sonic, Mega Man, and Donkey Kong are the only characters to be playable in fighting games outside the Super Smash Bros. series.

In Link's case, he appeared in the GameCube port of Soul Calibur II, as a guest character for the platform. Some of Link's attacks in the game, such as his Boomerang, Spin Attack and Bombs, came directly from the Smash games.

Snake appeared in the Japan-only DreamMix TV World Fighters as a playable character.

Sonic appeared as a playable character in Sonic the Fighters (Sonic Championship in the USA) and Sonic Battle, which makes him the first character to have appeared in a fighting game of his series, which was then coupled by Mega Man.

Mega Man appeared in the Marvel vs. Capcom series as well as Mega Man - The Power Battle and its sequel Mega Man 2 - The Power Fighters, making him the second character in a fighting game of his series (the first being Sonic).

Donkey Kong appeared in Punch-Out!! for Wii as a secret opponent.
