Armstrong Houston is a bounty hunter who appears in the Super Metroid Nintendo Power comics series. He uses a version of Samus Aran's Varia Suit which is blue with a black visor, and appears more bulky, although it is said in the comics that it possesses lower shielding and the inability to recharge energy. He also possesses a gunship similar to the one Samus has in Metroid II: Return of Samus, Super Metroid, and Metroid Prime 2: Echoes. He does barely any fighting and is only around to collect bounties, but he does warn Samus of danger and cheers her on. He seems sort of desperate to be her partner and a few readers believe he may be romantically attracted to her. Also, due to the censoring of the comic's violence, it says that he collects "Space Pirate claws" instead of corpses.
Armstrong is also equiped with a variety of beam weapons quite similar to those used by Samus, these include the Pyro Beam (Plasma), Arctic Beam (Ice), the all-familier Power Beam, and his last and most powerful, the Electron Beam which looks almost exactly like the Phazon Beam used at the end of Metroid Prime as well as its unique abillity to arc from object to object, wether it be living or non-living.
After his debut in the comics, he has been adapted into a more powerful and serious character for a variety of fan fiction works.
