At long range, he can charge up for a powerful yellow ball to attack. His melee attack is named Dash Punch and his ranged attack is named Energy Ball.

Super Karate Wave
When the boss slots land on three Zen Sensei icons, a Super Karate Wave will occur. During the wave, Karate Zombies replace all regular zombies.
