Necrodeus

Necrodeus is the main villain of Kirby Mass Attack. He serves as the final boss in the game.

He is a "head and hands" boss, similar Wham Bam Rock and Wham Bam Jewel from Kirby Super Star (Ultra), and Master Hand and Crazy Hand from Kirby & the Amazing Mirror.

Physical Appearance
He has red eyes, a pointed face, horn-like ears, sharp teeth, and pale purple complexion. In a way, he resembles Nightmare from Kirby's Adventure. His only garment is a black cloak. He wields a scepter which he used to split Kirby into ten Kirbies at the beginning of the game, but it serves no other purpose in the game, story or boss battle or otherwise.

Attacks
He first attacks with his hands by slamming them onto the ground, or trying to catch the Kirbies between them. Sometimes he shoots small plasma balls that bounce around temporarily. At some points in the battle, buttons appear on the back of his hands. Touching them with the stylus hurts him. After you hit both buttons, his hands explode and the ground disappears.

His head then goes onto the bottom screen and either shoots out large plasma balls that bounce across the screen slowly, or charges a laser cannon that the Kirbies need to attack before being shot by. He occasionally summons 3 "Skull-Ghosts" that try to pick up a Kirby and drop it into his mouth and destroy it. After you doing enough damage to Necrodeus' laser, his entire head cracks. If the Kirbies attack him now, he explodes and the game is won.

Trivia

 * In the beginning of the game, Necrodeus has a cape, but it is not seen in the battle.
 * Necrodeus seems to emit a deep cackle in battle, making him the third final boss to cackle during the fight against him, the other two being Drawcia and Marx/Marx Soul.
