King of the Beasts III (Merciless)
百獣王Ⅲ 超極ムズ
King of the Beasts III (Merciless) is a Battle Cats stage in Hunt for the Xenobeast. It costs 200 energy and sends 10 enemy spawn lines — led by Xenobeast Bunaglios as the boss — against a 1,400,000 HP enemy base, and clearing it rewards 18,800 XP. Its enemies carry the Red, Floating, Relic, Alien and Behemoth traits, so cats that target them do the most work here.
