Like Crazed Moneko, Corrupted Moneko has moderate range, many knockbacks and a multi-hit attack with a 100% chance of creating a Lv. 5 Shockwave on the third hit. Unlike her cat counterpart, the enemy version can only has a 50% chance to do a Critical Hit, while the allied version is able to Critical Hit at a 100% chance.
Strategy
When fighting this enemy by herself, it is sufficient to send out only an occasional Manic Mohawk Cat to trigger her attack animation. As long as no units with a range under 240 are deployed during her attack, she will be unable to produce a Shockwave, making her much less of a threat. When there are other enemies on the battlefield, then just enough meatshields must be deployed to keep your backline attackers safe without allowing her to hit anything with her last attack.
It is ill-advised to use Metal Cat or other meatshields/close-ranged attackers that can survive the first two hits of Corrupted Moneko's attack, as they can easily give her a chance to unleash her Shockwave. The only Wave Shields that won't backfire on the player are Eva Unit-00, Hatsune Miku: MM2020 Tokyo and Doom Engine Pandora.
At 100% strength magnification, Corrupted Moneko has the exact same stats as Crazed Moneko, the difference is that Crazed Moneko is never seen at 100% strength magnification, while Corrupted Moneko is.
