Charge Kick

Charge Kick (チャージキック) is the Special Weapon obtained from Charge Man. By incorporating Charge Man's power to his slide, Mega Man causes a strong shockwave while sliding. 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 (but not Wave Man's own waterspout). 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. Unlike a regular slide, the player cannot change direction in the middle of a Charge Kick, even if they are in a place where sliding is the only way to get through. Charge Kick does 1 damage to enemies, excluding weaknesses.

''It is physically impossible to deal damage to Gravity Man or any of the Wily Castle bosses. The Charge Kick ends as soon as Gravity Man shifts gravity and all Wily Castle bosses have weak points that must be hit with a ranged weapon or at least one that can be aimed (either because they are flying or have weak points above the ground).''
