Ghost King III (Merciless)
妖怪大王Ⅲ 超極ムズ
Ghost King III (Merciless) is a Battle Cats stage in Invasion of the Swamplord. It costs 200 energy and sends 11 enemy spawn lines — led by Kappy Kawano as the boss — against a 1,400,000 HP enemy base, and clearing it rewards 18,800 XP. Its enemies carry the Alien, Red and Black traits, so cats that target them do the most work here.
