Fire Storm

Fire Storm (ファイヤーストーム) is Fire Man's Special Weapon. It shoots a fireball forward and causes a small flaming orb to circle the user, providing a brief shield effect. Both the fireball and orb can cause damage.

In the Mega Man Archie Comics serial, Fire Storm was used by Fire Man and copied by Mega Man. In one of the Short Circuits, Mega Man briefly imagined Roll using Fire Storm to clean up a basement when forgiving Mega Man for his earlier actions in Issue #3.

Trivia

 * Mega Man is seen using the Fire Storm against Ice Man in the intro to the cartoon, using it to simultaneously set his parka on fire and blow him away, also defrosting a frozen area of the city. However, in the games, Ice Man's weapon is actually Fire Man's weakness. This problem also occurs in the commercial for Rockman on Famicom. Not only did Mega Man defeat Ice Man with one shot from Fire Storm, this also contradicted his weakness in the game itself.
 * In Mega Man Megamix, in Napalm Man's profile, it states that the scattering explosion produced by Napalm Bomb is called a Fire Storm.
 * It is considered the series' first shield weapon.
 * It can be used effectively against Quick Man in Dr. Wily's Revenge. When Quick Man get close to the player, the fiery orbs can deal damage to him.
 * It is the first shield-like weapon that can be used in destroying Pipi birds as they keep spawning, to collect lots of dropped Power-ups.
