Kabuki Z is the third boss from M.U.S.H.A..
Kabuki Z appears as a large red mech. It will show up right at the beginning of the stage, dropping bombs on the floor to launch debris then stopping to shoot energy balls at the player. Upon taking some damage it will retreat, appearing again at the end of the stage.
It will show up inside of a large floating shell with two faces, surrounded by many orbiting spiked balls and using the smae energy balls attack. Upon taking enough damage the shell will blow up, revealing the boss who will then float about with the spiked balls serving as a tail while shooting the energy balls.
