The Nightmare Wizard, also known as Nightmare, is the final boss of Kirby's Adventure and its remake, Kirby: Nightmare in Dreamland, whose goal is to spread his nightmares across the land by taking over the Fountain of Dreams. He is ultimately defeated by Kirby with the help of King Dedede and the power of the Star Rod.
In Smash Bros., his ominous form appears in the background before engulfing the stage in total darkness, causing confusion for human and computer players alike.
