Ruthless Tyrant (Merciless)
来怨キング 超極ムズ
Ruthless Tyrant (Merciless) is a Battle Cats stage in The Malevolent Cow. It costs 200 energy and sends 7 enemy spawn lines — led by Brollow as the boss — against a 2,500,000 HP enemy base, and clearing it rewards 18,800 XP. Its enemies carry the Aku and Floating traits, so cats that target them do the most work here.
