Hyper Zone is the space above Dedede's Castle in Kirby's Dream Land 3 where Kirby and Gooey battle 0. The area is only reachable once Kirby has obtained the Love-Love Stick.

Appearance

Hyper Zone itself is a blue void with blobs of black Dark Matter swooping around chaotically. It has no theme of its own, since it is exclusively used during the fight with 0; so only 0's battle theme is heard. In Dream Land 3's Boss Butch mode, Hyper Zone becomes yellow, and the swirling Dark Matter srrounding Hyper Zone becomes red and blue.

Trivia

• Hyper Zone is named after a shooter game called HyperZone that HAL made for the SNES in 1991.
