nightmare (kirby)

"It was a mistake for you to come here, Kirby. As you can see, you and your puny Star Warriors are no match for me. Challenging me is the last mistake you will ever make."

-- Nightmare - Combat Kirby

Nightmare is a major villain hailing from the Kirby series of games. He first appears in Kirby's Adventure as the game's final boss, and he desires to spread nightmares all across Dream Land.

He also appears in the anime as the main antagonist, where he desires to conquer the universe by selling monsters, usually to someone like King Dedede. The monsters, along with several other creations, come from his company Nightmare Enterprises.

The villain, as his name suggests, is a living nightmare, and his one and only weakness is the Star Rod.
