The platform fighter genre has typically been thought of as having originated with the Super Smash Bros. franchise, to the point where it is common for the genre to be called "Smash Clones". However, while Smash did introduce almost all of the defining mechanics to the subgenre, such as ring-out based KOs, wavedashing, and the 3/4-way-input special move system, there are at least two titles that predate Nintendo's crossover and attempted to merge platforming with fighting gameplay - the multiplayer mode within 1991's Captain America and the Avengers for NES, and 1995's arcade title The Outfoxies. Both titles had characters with limited movepools compared to the style Smash would popularize and were lifebar-based. The Outfoxies also included damaging stage hazards and items, two mechanics popular within Smash but scantly used in other platform fighters.

Also of mention is Savage Reign, a traditional fighting game from 1995 featuring a platform gimmick, though this game has far less in common with platform fighters than The Outfoxies or Captain America, simply serving as a traditional fighting game with two planes to stand on as opposed to mobility-based platforming.

It is not known if anyone who worked on Super Smash Bros. was aware of or consciously took inspiration from these 3 games.
