Hot-Headed Echidna
マジメすぎるアツい男
Hot-Headed Echidna is a Battle Cats stage in Sky Sanctuary. It costs 200 energy and sends 9 enemy spawn lines — led by Knuckles (Enemy) as the boss — against a 240,000 HP enemy base, and clearing it rewards 352,500 XP. Its enemies carry the Floating and Red traits, so cats that target them do the most work here.
