Zero Knuckle

The Zero Knuckle is an exclusive weapon used by Zero in Megaman Zero 4. It took the place of the Shield Boomerang and the Rod weapons that had been in previous MMZ games. The Zero Knuckle is represented by two Zs on the palms of Zero's hands. These Z-chips allowed Zero to punch an enemy for low damage, but also to grab and pull a part of the enemy off for use by Zero. The part can have a number of uses, some of which have limited ammunition. You can also use it to affect the environment. Like Zero's other weapons, elemental chips can be used with this weapon when charged.
