This feature has become unobtainable and can only be obtained via hacking.

This article lists all features that are currently unimplemented. It does not include features that were once in the game but were eventually removed (such as Serial Codes).

Evangelist Cat

Evangelist Cat is an Uber Rare Cat that was once obtainable through a limited-time event in the Korean Version, but also exists in the files of the Japanese, English and Taiwanese Versions. The Battle Cats Unite! uses it as a reward for completing Cats of the Cosmos, but it remains unused in the mobile versions of the game.

Chicken Cat

Chicken Cat was an Uber Rare Cat that was part of partner-works with Nobe_tto (のべぇ〜っと), creator of "Life of Chicken and Chicks". It was never obtainable through any known means, and was eventually removed altogether in version 8.7.

Maneki Cat

Maneki Cat is a Special Cat that was once obtainable through a limited-time event in the Japanese Version, but also exists in the files of all other versions; however, it is unobtainable in them.

Enemy IDs 21 and 22

Enemy ID 21 shares Zoge's (ID 286) sprites and animations, but has completely different stats. This enemy slot has always been unused: it and ID 22 separate the enemies found in the original mobile phone version of the game—ending with The Face at ID 20—from the ones added later on, starting with Ms. Sign at ID 23. It seems that the slot was used to test Zoge's animations, and the developers simply forgot to delete the unused data. Also, in previous versions, the image file for this enemy housed a red Master A. recolor named "Bloodsucker"; this was presumably an early version of Professor A.

Enemy IDs 566 to 571

Enemy IDs 566, 567, 568, 569, 570 and 571 share Doge's stats, sprites and animations, but are traited as Aku. Since these IDs come right after Wicked Cat, Wicked Tank Cat and Wicked Axe, it is possible that they are stand-ins for Wicked versions of the other six Normal Cats.

Unused Unit Sprites


Mr. and his evolved form, Super Mr., use the same spritesheet internally, even though Mr. carries a shotgun while Super Mr. uses a bazooka. Also, the spritesheet has an unused missile in it. This same missile would later be used in Tricycle Cat's spritesheet.

Tricycle Cat

Tricycle Cat's spritesheet includes an unused greyscale version of the missile he normally shoots in his attack animation.

Biker Cat

Biker Cat's spritesheet has considerably more unused sprites than its pre-evolution, including three unused missiles, a sonic boom, and a red version of the spikes he normally ejects from his front wheel to attack. It seems that he was originally meant to fire a much bigger missile than his pre-evolution; the missile is still present on the in-game model, but does not animate and is set to 0% opacity.

Cat Base Mini

All three members of the Cat Base Mini evolution line have unused sprites. Cat Base Mini and Cat Base Jr. both have duplicates of the wave effect from the Cat Cannon. In-game, both of them instead use the same wave effect as every other unit.

Cat Base Ultra

Cat Base Ultra doesn't have the unused wave effect, but it does have an unused Li'l Cat head present. It's unknown where it would have been used, as it's too big to fit inside the base's door or the top port.

Drumcorps Cat

The spritesheet for Drumcorps Cat includes sprites for two additional Cats, a tuba, drumsticks, and particles relating to them. However, in-game, only the leading Cat with the baton is used.


Kachi-Kachi's spritesheet has one more unused frame of animation for the tanuki in the top-right corner.

|Kachi-Kachi's spritesheet


Supercat's spritesheet includes four rectangles, coloured dark yellow, cyan, magenta, and dark green, respectively. These are not assigned to any parts on the model. Strangely, they're also nowhere to be found on the spritesheet of Mightycat, the basic form.

Bakery Cat

There's an unused impact effect on Bakery Cat's spritesheet. Technically, the sprite is used during gameplay; however, it's set to 0 opacity, so it never renders during the attack animation. It also appears on Boomerang Cat's spritesheet, where it "animates" in the exact same way.

Bronze Cat Base

An unused enemy base featuring Bronze Cat can be found in the game's files, suggesting that Bronze Cat was originally a Monthly Event unit or that Cyclone Stages were originally going to have their own bases.

Region Exclusives

Certain region-exclusive units and stages (including collab ones) exist in the files of all versions, but with their sprites removed. Some use placeholders for their names and descriptions, but others have official translations.

Unused Catfruit

There are three types of Catfruit that are not used in-game. When hacked into the Catfruit Storage, the unused types only show as white circle with the kanji "仮" (meaning "temporary") written over it in BCJP, or as black boxes in other versions. When exchanged, they give 500,000 XP each.

Sono 1

その1 (Sono 1, lit. "Part 1") was the placeholder name for an unfinished stage which cost 150 energy to play. The only enemies known to appear were Cruel Angel Clionel and Gentleman Bros., who spawned together at the beginning to form a nightmarish combo in which Clionel would annihilate your backlines and Gentleman Bros. would freeze anything that could enter her blind spot. It later became Old Master (Expert), with which it shares an ID.

To the Future and Droid Awakens!

To the Future and Droid Awakens! are stages exclusive to the Google Android Collaboration Event in Nyanko Daisensou. Both exist in the English Version as well, but neither has been released.

The Battle Cats Together! and Cat Bros

The Battle Cats Together! is a Nyanja Daisensou-exclusive tie-in event with The Battle Cats Unite! that drops Rare Cat Cat Bros. Even though The Battle Cats Unite! has not released outside of Japan, both the event and the units have existed in all versions for years.

Warp Resistant and Improved Knockback

These abilities have been in the Cat Filter since version 8.0 and are presumably meant to be unlocked through Talents, but neither is actually assigned to any unit.

Traitless Icon

Ever since the Version 8.0 Update, within the game's files, a White (Traitless) target icon is able to be found among the many other traits the game has.

Unused Enigma Maps

Only three Enigma rarities exist in the game, but sprites for two more can be found in the game files, as well as a platinum Enigma in the first image for the Enigma Stage tutorial. The former two may have simply been the original designs for Normal and Superior Enigmas.

Traitless and Relic Talent Orbs

Although Traitless and Relic do not have associated Talent Orbs, the game files have had sprites of Talent Orbs for both since version 9.7.
