Red Frontier

紅き本能の秘境

Red Frontier is a Battle Cats stage in Island of Hidden Treasure. It costs 300 energy and sends 8 enemy spawn lines — led by J.K Bun Bun as the boss — against a 890,000 HP enemy base, and clearing it rewards 26,790 XP. Its enemies carry the Red and Floating traits, so cats that target them do the most work here.
