Crazed 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.
When fighting Crazed 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.
At 100% strength magnification, Crazed Moneko has the exact same stats as Corrupted 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 Corrupted Moneko, she was the first enemy to have an ability that only activates on one part of a multi-hit attack.
