Homing Torpedo (Mega Man)

Homing Torpedo (ホーミングトーピード Hōmingu Tōpīdo) is the Special Weapon that X obtains from defeating Launch Octopus in Mega Man X. When equipped, X fires a small missile that seeks out the nearest enemy. If there or no enemies nearby, the weapon will simply fly in a straight line. Despite its "torpedo" moniker, it can be used both in and out of water, much like the amphibious Dive Missile from the original series. Up to two Homing Torpedoes can be fired and be visible on the screen at a time (three in Maverick Hunter X). When fully charged, X will fire four (six in MHX) quick piranha/angelfish-like missiles; along with having increased firepower, these torpedoes boast a more fluid mobility and faster traveling speed that grants its homing capabilities with a higher degree of accuracy onto nearby targets than if uncharged, and is useful when faced with numbers of enemies.

This weapon is Boomer Kuwanger's weakness. Vile is also susceptible to the Homing Torpedo as well.
