Otherworld Colosseum · Stage 1
Round 1
Round 1 is a Battle Cats stage in Otherworld Colosseum 12. It costs 200 energy and sends 10 enemy spawn lines — led by Razorback as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Black and Floating traits, so cats that target them do the most work here.
