Yet another entry in the "powerful and fast enemy" category, Beefcake Cat is a force to be reckoned with at the best of times having massive health, deadly attack power, somewhat short range to bust past your Cats, fast attack speed, and area attack.
Strategy
The easiest way to kill it is by using long ranged attackers such as Radiant Aphrodite and Windy, and if you have a slow or freeze unit that affects Floating, use them unless they get outranged.
Beefcake Cat is a Floating enemy. As such, some anti-Floating units who outrange him can be used to deal with him.
