Hyper Zone

Hyper Zone is the last level in Kirby's Dream Land 3, where Kirby fights Dark Matter and Zero. It is the ominous mass of Dark Matter's cloud that is hovering over Pop Star during the game. The player gains access to it by collecting all the Heart Stars.

Intro
All the collected Heart Stars coalesce and form the Love-Love Stick. Kirby grabs it and flies into the ominous space above while everyone watches from below.

General Information
Hyper Zone's environment resembles a big, blue oblivion with Dark Matter-esque blobs sailing through it. Hyper Zone's counterpart, Dark Star in Kirby's Dream Land 3's sequel, Kirby 64: The Crystal Shards, appears as a red oblivion with ribbons of Dark Matter energy.

The level is thought to be named after an SNES shooter also developed by HAL Laboratory, which uses the name as the final level and Ripple Field as one of the levels, as well as Grass Land.

Trivia

 * In Boss Butch, Hyper Zone takes on a yellow coloration instead of blue, with blue and red blobs instead of black blobs sailing through it.
 * The blobs in the background move faster with each fight, starting quite slow with Dark Matter, faster with Zero, and extremely fast with Zero's Eye.
