Charge Kick

Charge Kick (チャージキック) is Charge Man's special weapon. To activate this power, Mega Man must slide while the weapon is active, causing damage with his slide and being immune to some attacks and traps while using it, such as the steam vents in Wave Man's stage. This is useful against some low-to-the-ground enemies. In Mega Man IV, it can break some blocks. Due to being a short-range weapon, Mega Man may get hit by enemies if he stops near them.

Capacity
In Mega Man 5 and Mega Man IV, one Charge Kick uses 1 weapon energy unit. With a full weapon energy gauge, Mega Man can use Charge Kick 28 times in Mega Man 5 and 19 times in Mega Man IV.
