The leader of the dark matter force, Zero continued the trend of creepy final bosses for Kirby games(started by Nightmare, and continued by Marx), but in how he attacks instead. Design-wise, he is pretty basic (probably even more than the regular Dark Matter and Dark Nebula), but how he attacks, is kind of disturbing. He attacks by launching blood out of slits near his eye. When you beat his 1st phase, he gets even creepier. The eyeball comes straight out of his body to chase you, along with a seething trail of blood. That phase is pretty easy, but this 1 boss fight was enough to change Kirby's Dreamland 3 to E-10 when it hit the Wii U E-shop. But when you kill Zero, he still wants to settle the score with the pink puffball...
