Three Evil Brothers
極悪三兄弟とのデュエル
Three Evil Brothers is a Battle Cats stage in Castle of the Sentinels. It costs 185 energy and sends 4 enemy spawn lines — led by Koronium as the boss — against a 920,000 HP enemy base, and clearing it rewards 297,369 XP. Its enemies carry the Metal and Red traits, so cats that target them do the most work here.
