Unused content refers to removed bits of games that can be found in magazine pre-release images, pre-release videos, and occasionally on the developer's or producer's own site. Another form of removed content from final game versions can be found through using hacks, glitches, and emulator cheats. Although specific content revealed to be beta was removed from the final pressing of the title, subtleties resulting from the ideas from the beta may remain.
List of unused content by game
The following lists every notable bit of unused content still present in the files and data for games in the Kirby series. Note that any additions to this list will require some sort of evidence in the form of an image or link.
Kirby's Block Ball
Sprites for a Waddle Doo are found in the game's files. Defeating him would cause him to lose his eye.
Kirby Squeak Squad
- Main article: Block (copy ability)
An unused design for a Copy Ability exists in the game's files called 'Block'. It is unclear how exactly this ability would have functioned.
Kirby's Return to Dream Land
A number of unused ability icons exist in the game's files. Among them include icons for super versions of Cutter and Spark. Additionally, a pair of icons with a clock inset are present, and it is unclear if they had represented a new Copy Ability, or are merely a placeholder left in the game.
Kirby: Planet Robobot
- Cappy was meant to have an attack that allowed him to toss his cap between foreground and background. A full working version can be found in the game, but it was never implemented.
