Fan Casting Super Smash Bros (1992)

In the Adventure mode titled "The Subspace Emissary", Mario and Kirby face each other on a stadium located in the Smash Bros. world. In this world, when a fighter is defeated, they become a trophy which can be revived by touching the base. Suddenly, the Battleship Halberd appears, releasing a stream of black, purple-clouded Shadow Bugs that form the soldiers of the Subspace Army. The Ancient Minister, the cloaked, mysterious Subspace General, arrives and detonates a Subspace Bomb, which can only be detonated by the sacrifice of two R.O.B units, and transports the stadium into Subspace, an alternate dimension where the Subspace Army resides. The Ancient Minister's advance prompts the heroes to ally and attempt to repel the enemy, while villains harvest the power of the allied characters by using dark cannons to convert them into trophies and using Shadow Bugs on some of them to create powerful doppelgängers. King Dedede begins independently gathering some fallen fighters' trophies, placing golden brooches on them.
