A Copy Essence is an object which gives Kirby the associated Copy Ability if Kirby moves over it. The Copy Ability it gives is traditionally indicated by the enemy on the Essence; the same enemy which gives the ability when inhaled. It is first introduced in Kirby Super Star, although its concept and appearance is very similar to the museums in the earlier Kirby's Adventure. In Kirby's Return to Dream Land however, the Copy Ability given by the copy pedestal is represented by the Copy Ability's unique Ability Star instead of the enemy.
Copy Essences are fairly common. A certain number of them are almost always found before a boss fight (and, in rarer cases, a mid-boss fight), and the selection of abilities they give is usually fairly useful against the specific boss. Before the introduction of the Copy Essences, Copy Abilities are similarly presented before boss fights in the form of regular enemies completely enclosed within the ground, but this is rather unrealistic, and the enemies are not as harmless as the Essences, as certain ones can hit outside the barrier they are encased in. Also, if Kirby inhales the wrong enemy, they have to be respawned by moving off-screen, which is sometimes impossible to do without triggering the boss fight.
Instead of Kirby having to face the boss without any Copy Ability or having an unsuitable one which is better off used performing the Star Spit, it is usually better off to grab an ability from one of the pedestals unless the player is using special or universal abilities, or that the ability has uses elsewhere, like Master, Smash, Triple Star, Hammer, UFO or even Plasma.
The Copy Essence replenishes itself after being used after Kirby no longer touches it, which makes it particularly useful for experimenting with Copy Abilities or the creation of specific Helpers in Kirby Super Star and Kirby Super Star Ultra. Due to their very nature, the Copy Essences cannot be used to perform Mix, however.
With the Sleep Essence in particular, Copy Essences can become a nuisance, as moving over one causes Kirby to discard his current ability (except in Kirby & The Amazing Mirror), whatever it may be. In The Great Cave Offensive, there is a particular sequence with a large number of Sleep Essences which Kirby must navigate while braving strong winds to get at a treasure chest inside the Old Tower. A.I.-controlled Helpers are also sometimes prone to moving over Essences and changing their form to one less suitable for an upcoming battle.
In certain games, an area with (almost) all of the Copy Abilities in the form of Copy Essences can be unlocked by certain means.
|Dyna Blade sub-game, Kirby Super Star / Ultra||Activating two hidden switches unlocks Trial Rooms 1 and 2, respectively. Sleep is not present. Crash, however, can be obtained from the Bomber in Trial Room 2.|
|Kirby & The Amazing Mirror||The Golden Door (not the Dimension Mirror) is unlocked after all the big Switches are activated and all regions are connected to the Central Circle in Rainbow Route. The Master Sword is found in the Central Circle instead of inside the Golden Door after the game is completed. UFO is not present, however.|
|Kirby: Squeak Squad||Finding all the pieces of the Secret Map in treasure chests unlocks the Secret Area. Triple Star is found inside here after the game is completed.|
|Kirby's Return to Dream Land||Four Copy Ability Rooms are located on the Lor Starcutter. To open them, Kirby must collect the number of Energy Spheres required. The first room requires 20, the second requires 40, the third requires 60, and the fourth requires 80. Each room contains five Copy Essences and a training dummy for Kirby to test his abilities on. The Limited-use abilities and Super Abilities are not present.|
|Kirby: Triple Deluxe||Beating Story Mode will allow Kirby access to the Copy Ability Testing Room, which can be accessed by descending the Dreamstalk. Located there are all the Copy Abilities in the game, excluding Hypernova and Sleep, and a Tough Waddle Dee, which can be used for training.|
Copy Essence Deluxe
|Main article: Copy Essence Deluxe|
In the Milky Way Wishes sub-game of Kirby Super Star and Kirby Super Star Ultra, there are no traditional Copy Essences available (except during the Computer Virus boss fight) and Kirby can only copy rarely-available limited-use Copy Abilities by means of his inhale. Nineteen Copy Essence Deluxes are hidden throughout the levels, and upon touching one of these, Kirby gains the use of the Copy Ability permanently within the context of Milky Way Wishes, able to swap in and out of all such Deluxe abilities at any time.
- In all versions of The True Arena, in the rest area, a Sleep Copy Essence will always appear alongside a different Essence. Sometimes both Copy Essences will grant the Sleep ability.
