Battle Cats | A Cat Screaming Love (Merciless)
Best way to do this stage is basically rush it as shown here. You don't necessarily need your worker cat to be at full level once you kill off the starting relic doges, but you should have a good bit of money. Can Can deals with the first wave of relic doges then manic flying for the others. When timing Awakened Bahamut and Manic Lion, you'll most likely have some Manic Flyings on the field. Try to summon Lion + Baha not too late when the flyings are closer to the base because as I've seen in previous runs, the flyings advance too much and clionel activates attack much quicker, something you want to avoid. You do want the manic flying in close proximity so that he can help kb heavenly hippoe though. The gabriel from the base makes clionel miss bahamut, so don't worry about that. Then just time your cat cannon after bahamut kb hippoe to cancel clionel attack and then spam to win afterwards. Your ramen mostly keeps the peons from killing bahamut, but sometimes he will die, which is why zamboney is good for this. Pretty all there is to the strategy.
