Top Spin

Top Spin (タップスピン) is Top Man's special weapon. To activate it, Mega Man must be up in the air and press the attack button to spin.

Capacity
In Mega Man 3 and Mega Man II, Top Spin uses one weapon energy unit when it hits an enemy. Using it without hitting anything will not use up energy. In Mega Man 3, Top Spin will always use energy when it hits a target, even if it is not affected by it. In Mega Man II, it only uses energy if the target is damaged.

In Mega Man 3, the energy usage of this weapon is unique and somewhat unpredictable. If it is used after getting hurt in the invincibility state, it will drain all of its energy in some cases (due to it counting as multiple hits). A few times it also doesn't use energy, like when using it in Hammer Joe's projectiles. Although the less direct contact Mega Man has with the target, the less energy will be used up while the more Mega Man's sprite is contacting with the target's sprite, more energy will be used up. Usage may hurt Mega Man if he touches an enemy that isn't destroyed in one hit (or if the enemy is explosive).
