Earth

地球

Earth is a Battle Cats stage in Cats of the Cosmos Ch. 2. It costs 60 energy and sends 3 enemy spawn lines — led by UltraBaaBaa as the boss — against a 300,000 HP enemy base, and clearing it rewards 1,000 XP. Its enemies carry the Alien trait, so cats that target it do the most work here.
