The saga ends with the Cat army deciding to build a rocket to venture further into space and continue the fight against the aliens.

However, the Aliens out in space are unlike those on Earth, as their power is enhanced with stars and they can warp Cat units away and nullify damage with barriers.

However, an entity of chaos and destruction known as Filibuster Obstructa arrives from outside the galaxy, serving as the Cat Army's final test in their conquest of the Cosmos.

Upon entering the Aku Realms, the Cats find more altars that weaken them, which the dark priest Mamon built to prevent others from interfering with his plan.

He seeks to unleash the god of destruction, Jagando, the Lord of Ruin, by undoing the seals of power the heroes of legend placed on him.

After emerging victorious, the Cats soon find that the laws of this universe are drastically different from their own, with natural phenomena such as snow in volcanoes and forests filled with poisonous gas.

These enemies can have traits such as "Red", "Floating", "Black", "Metal", "Angel", "Alien", "Zombie", "Aku", "Relic", "Traitless", "Behemoth", "Colossus", and "Sage".
