Charge Kick

Charge Kick (チャージキック) is Charge Man's special weapon. To activate this power, Mega Man would have to slide while the weapon is active, causing damage with his slide and being immune to some attacks while using it. This is useful against some enemies low on the ground. In Mega Man IV, it can break some blocks. Due to being a short range weapon like the Top Spin, Mega Man may get hit by enemies if he stops near them.If you use the Charge Kick, you can slide through the steam holes in Wave Man's level unharmed.

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.
