Feathergeddon III (Merciless)
一石三鳥Ⅲ 超極ムズ
Feathergeddon III (Merciless) is a Battle Cats stage in Invasion of Poultrio. It costs 200 energy and sends 12 enemy spawn lines — led by Poultrio as the boss — against a 1,400,000 HP enemy base, and clearing it rewards 18,800 XP. Its enemies carry the Aku, Angel, Red and Black traits, so cats that target them do the most work here.
