Zero

Zero is the final boss of Kirby's Dream Land 3. It is a form of Dark Matter. He has three different forms.

Form 1
Zero, in this form, looks like a normal black ball of Dark Matter, except it has orange spots along his edges. He attacks by shooting black lightning at Kirby.

Form 2
In this form Zero looks much like the Zero most people know it as. It shoots blood from cuts it opens around its eye, and sometimes shoots little balls of Dark Matter for Kirby to take care of.

Form 3
Once you defeat Zero's second form, its eye pops out and you have to defeat its eye. After you do that, the game is done.
