Possessed by Evil (Merciless)
魔王憑依 超極ムズ
Possessed by Evil (Merciless) is a Battle Cats stage in Prelude to Ruin. It costs 200 energy and sends 10 enemy spawn lines — led by Evil Emperor Cat as the boss — against a 1,222,222 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Relic and Red traits, so cats that target them do the most work here.
