Dark Missile Trooper

The Dark Missile Trooper is a Galactic Federation Marine Corps Missile Trooper possessed by Ing. It is slow because full parasitic fusion has yet to take place. It shoots Missiles at enemies with its Missile Launcher. It is the only optional boss in the entire game. The Dark Missile Trooper retains the Darkling weakness of light, thus it is easy to defeat with the Light Beam. This boss is also easy to defeat using a charged Dark Beam and a Missile. It is possible that the Ing possessing the body is the one that stole the Missile Launcher, especially since the Missile Expansion it drops looks like the Missile Launcher as opposed to a regular Missile Expansion.

Trivia

 * The Dark Missile Trooper is the only optional boss of the game, found near the landing base.
 * If the player obtains a Missile Launcher before fighting the boss, the missile tank that the trooper carries will act like a normal Missile Expansion.
