Nightmare (Kirby)
From Multiversal Omnipedia
Nightmare is an evil demon who tried to invade Dreamland. King Dedede thwarted this by stealing the Star Rod from the Fountain of Dreams, closing off the demon's access point at the fountain. Dedede then shattered the rod and gave its pieces to his lieutenants to take to the far corners of Dreamland.
When Kirby gathered the pieces of the rod together and put it back in the fountain, Nightmare attacked, and was only narrowly defeated by Kirby using the rod.
