Cats of the Cosmos (often abbreviated to CotC) is the third saga in The Battle Cats. Like the previous sagas, it contains 3 Chapters, each with 48 stages. Cats of the Cosmos features many of the enemies introduced in Into the Future, as well as some new enemies and Stories of Legend enemies.

The main gimmick of this saga is the introduction of "Starred" Alien Enemies, which are unaffected by the anti-Alien crystal Treasures from Into the Future. Starred Aliens have a 1600% strength magnification by default, which can only be reduced by collecting the Treasures in Cats of the Cosmos.

Chapter 1 of Cats of the Cosmos is unlocked by completing Into the Future Chapter 1 and was added in version 6.5, while Chapter 2 was added in 7.2. Chapter 3 was released in update 8.3 JP. It is currently yet to be released for BCEN. No Treasure Festivals are officially scheduled on the weekly event chart yet, and may only appear in events.

New Features

Elite "Starred" Aliens

This saga introduces a variant of the Aliens that can be identified by a yellow star badge on a part of their bodies. Even though they are categorized as Aliens, the Crystal Treasures collected in Into the Future don't affect them. They initially have a 1600% strength magnification. Collecting all Superior anti-Starred Alien Treasures in a CotC chapter will reduce their stats by 500% (1600% - 1100% - 600% - 100%).

This saga expands the series of "elemental" fruits that increase the effect of certain abilities against a particular type of enemy. Titanium Fruit (Metal), Antimatter Fruit (Zombie) and Enigma Fruit (Alien) are available to collect here as well as Treasure to increase XP earned, max energy and five sets of Treasure for weakening the Starred Aliens. The last treasure on the list is needed to weaken the final boss of the chapter.


For the full article, see Special Abilities.

This saga introduces the Warp, Warp Blocker, Barrier and Barrier Breaker abilities. Enemies with the Warp ability have a chance to bring one or a group of Cats they hit back a specific distance after an amount of time; Cats with the Warp Blocker ability will ignore this effect; Enemies with the Barrier ability are able to ignore any damage that is weaker than the limit of their barrier. Each enemy has a barrier with different limit and it is not affected by strength magnification, Massive Damage effects do not work on the barrier as it requires raw damage to break, the player only needs one hit strong enough to break it. After breaking the barrier, the enemy is vulnerable to all attacks; Cats with the Barrier Breaker ability have either a percentage chance or are guaranteed to break barriers, without having to deal higher damage than the Barrier limit.


This saga introduces new restrictions. Every 3 stages has different restrictions, with a few exceptions. The restrictions are as listed:

  • Many of the enemy bases and Treasure names are pop culture references.
  • Most of the stage names and individual Treasure names are reused from Interstellar Invasion, which is Chapter 3 of The Battle Cats POP!.
  • Most Anti-Starred-Alien treasures were named with a format "natural satellites, gemstone", e.g. "Phoebe Beryl" is named after Phoebe, a moon of Saturn and Beryl, a gemstone that has a golden colored variant. With the exception of "Stellar garnet" in which Stellar means "star". The only thing that it is related to moons is that moons can be find by stellar occultation (solar eclipse).
