Aku Reincarnation (Merciless)
悪魔転生 超極ムズ
Aku Reincarnation (Merciless) is a Battle Cats stage in Rashomon. It costs 200 energy and sends 13 enemy spawn lines — led by Sathankhamun VIII as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Aku, Alien, Angel and Relic traits, so cats that target them do the most work here.
