2020 Debut
2020年デビュー
2020 Debut is a Battle Cats stage in Pt. 2: Enemy Maneuvers. It costs 160 energy and sends 9 enemy spawn lines — led by Baron Seal as the boss — against a 720,000 HP enemy base, and clearing it rewards 14,288 XP. Its enemies carry the Red, Alien, Floating and Colossus traits, so cats that target them do the most work here.
