Dark Troopers are the bodies of Galactic Federation troopers that have been possessed by the Ing.


When Samus Aran traveled to Aether in search of the missing GFMC Task Force Herakles, she found every one of the troopers deceased. Shortly after this terrible discovery, the Ing possessed many of the corpses (though only in the Splinter Hive), "reanimating" them to attack her. For whatever reason, the Ing were unable to fully complete this possession, leaving the resulting Darklings with slow reaction times and poor coordination. They are capable of using the troopers' rifles and bayonets, but do not use the latter frequently. They are relatively weak, possessing only 25HP (Hard/Hypermode). Any weapon can be used to kill them, though a single, charged Power Beam shot from Samus' Arm Cannon is sufficient enough.

More Troopers become possessed when Samus returns to the Splinter Hive later in the game. The most notable example of this is when Samus acquires the Morph Ball Bombs and optionally returns to Hive Chamber A, where she will encounter a Dark Missile Trooper. It is also incompletely possessed, but has greater stamina than its fellow Darkling Marines.

Logbook entry

Bioscans indicate terminated lifesigns in this trooper, and the presence of an unknown biomass with parasitic tendencies. Though the trooper's armor has been compromised, the bulk of it remains intact. Weapon systems remain online as well. Full parasitic fusion has yet to be obtained, resulting in low agility and response time.


Federation Troopers are reanimated through Ing possession in the Command Chamber.

  • The Ing are able to complete their parasitic fusion in an instant with every other bioform in the game except for the Troopers and Missile Trooper; this is most likely due to the latter bioforms having been dead long before their Darkling possession.
  • The visors of certain Troopers' visors that are unbroken will shatter on the right side and fade completely black to match the uniform model of Dark Troopers; their eyes can also be seen glowing red through their broken visors.
  • Any Trooper corpse that possesses a Logbook entry will not be possessed. This is so players do not encounter problems finding one-time entries the first time around, especially if they aren't looking for them.
  • The Dark Trooper's slow and shambling gait, as well as the fact that they are dead bodies that rise and attack to begin with, seems to be based on that of a typical zombie in popular culture. This also makes them similar to the X-infected Zombie Researchers encountered in Metroid Fusion and to a lesser extent the Chozo Zombies (also infected by the X) in Metroid Dread.
  • In Metroid Prime: Episode of Aether, the appearance of the Dark Troopers is much more grotesque. Their entire faces can be seen, and when possessed, their eyes lose their pupils and veins pop up all over their faces.
  • In the Metroid Prime 2: Echoes: The Official Nintendo Player's Guide, the section detailing the debut of the Dark Troopers is titled "The Few, The Proud, The Dead", which is a reference to the tagline for the United States Marine Corps (The Few, The Proud, The Marines).
