Shotgun Ice

Shotgun Ice (ショットガンアイス) is the weapon that X obtains from defeating Chill Penguin in Mega Man X. In its normal state, X fires a shard of ice that can freeze and/or damage a target. Upon collision, smaller shards will be fanned out in the opposite direction. When charged, it creates an sled composed of ice that X can stand upon and ride for a short period of time. Spark Mandrill, Bospider, and Velguarder are especially weak to this weapon.

The nature of this weapon is similar to that of Freeze Cracker from Mega Man 7.

Trivia

 * In Mega Man X, because obtaining the Foot Parts for the First Armor is mandatory in Chill Penguin's stage as the capsule blocks the way to the boss, it is impossible to obtain Shotgun Ice while not wearing any piece of the armor under normal circumstances. To circumvent this, a special password or a code from an external cheating device (such asa Game Genie or a Pro Action Replay) must be inputted.
 * This problem is fixed in the remake Mega Man Maverick Hunter X as the Foot Parts are no longer in the way, or even in that same stage any more.
