Enemies made their debut in Super Smash Bros. Melee as part of Adventure mode. While there were only a few at the time, the number of enemies expanded greatly in Super Smash Bros. Brawl with its Adventure Mode "The Subspace Emissary," some of which created for that game mode.
Some of those enemies were also carried over to Smash Run, a mode exclusive to Super Smash Brothers for 3DS. Here's the listing of said enemies.
