Since she is a single-target attacker, Capy will always select the cats closest to her to attack. But Capy does disgusting damage to the cat that she selects to attack, barely oneshotting maxed-out Eraser Cats when her attack power is halved by the Weaken effect. She also has a 15% chance to do a Critical Hit and hit even harder. Even tanky cats that resist Red, like Sushi Cat and Cat Machine, will lose to Capy in a duel, because Capy has also been gifted with about half a million health.

She is very easy to stall with meatshields, as she is a single-target attacker. However, if she is supported by bosses like Teacher Bun Bun, the latter can wipe out all the shields for Capy, allowing her to hit stronger cat units (notably in Oil Platform and Morning Rush Hour).
Dread Pirate Catley in particular has an easy time repelling this enemy with heavy enough meatshielding.
