McCleaver

McCleaver, known as "Basarika" (バサリカ) in Japan, is a squat virus appearing in the Mega Man Star Force series. It is a relatively small virus, with large blades on his hands and a hockey mask. Other varieties include the McDicer and the McSlicer. A McCleaver randomly moves about the field until it intiates it's attack, trying to slice MegaMan three times.
