Otherworld Colosseum · Stage 1

Round 1

Round 1 is a Battle Cats stage in Otherworld Colosseum 17. It costs 200 energy and sends 13 enemy spawn lines — led by Professor A. as the boss — against a 1,000,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Angel and Red traits, so cats that target them do the most work here.
