Champion of the Underground Arena

地下闘技場チャンピオン

Champion of the Underground Arena is a Battle Cats stage in Strongest Things Alive. It costs 200 energy and sends 3 enemy spawn lines — led by Baki Hanma (Enemy) as the boss — against a 200,000 HP enemy base, and clearing it rewards 28,200 XP. Its enemies carry the Aku trait, so cats that target it do the most work here.
