Revenge of N-1 (Merciless)
N-1グランプリ決勝 超極ムズ
Revenge of N-1 (Merciless) is a Battle Cats stage in King Wahwah's Return. It costs 200 energy and sends 12 enemy spawn lines — led by King Wahwah as the boss — against a 1,500,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Black, Alien and Zombie traits, so cats that target them do the most work here.
