Corrupted Moneko has low range, many knockbacks and a multi-hit attack with a 100% chance of creating a Lv. 5 Wave Attack on the third hit. Unlike her cat counterpart, the enemy version can only Critical Hit at a 50% chance while the allied version is able to Critical Hit at a 100% chance.
Strategy
When fighting Corrupted Moneko by herself, it is sufficient to send out no meatshields or only an occasional Crazed Macho 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 Wave Attack, 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 who can survive the first two hits of Corrupted Moneko's attack, as they can easily give her a chance to unleash her Wave Attack. The only Wave Shields that won't backfire on the player are Eva Unit-00, Hatsune Miku: MM2020 Tokyo, and Doom Engine Pandora.
Multi-Hit (20,000 at 4f 0.13s, 20,000 at 19f 0.63s, 20,000 at 139f 4.63s) 100% chance to create a level 5 Wave Attack on third hit 50% chance to perform a Critical Hit on third hit
At 100% strength magnification, Corrupted Moneko has the exact same stats as Crazed Moneko. The difference is that Crazed Moneko only appears at 12% or 50% strength magnification, while Corrupted Moneko is at full strength in both of her appearances.
Along with Crazed Moneko, she was the first enemy to have an ability that only activates on one part of a multi-hit attack.
