Ridley (Metroid)
One of Adam's final missions to Samus is to finish off Ridley, whom Adam fears might be more dangerous than the Metroids if left unchecked, and claims Samus is the only one capable of stopping him. However, Samus later discovers his corpse after he is killed, having had his energy drained by the Queen Metroid on the Bottle Ship. His mummified corpse turns up again in "Metroid Fusion" on the BSL station, after having apparently been removed from the Bottle Ship by the Galactic Federation and placed in a sub-zero storage room for further research (potentially into further bioweapon applications). It is later infected by an X Parasite, allowing it to gain the ability to transform into Ridley's likeness, known as . Samus later defeats the Ridley mimic and absorbs its Core-X, regaining her signature Screw Attack. What was left of the cloned Ridley's remains were destroyed along with the X when the BSL station crashed into SR388.
Characters in the Metroid series
However, this project was foiled by the accidental cloning of Ridley and the rebellion of MB, the Mother Brain-like android created to control the Metroids. This leads to the interference of Adam Malkovich's team of soldiers and Samus. However, one of their operatives called ""The Deleter"" by Samus, infiltrates Adam's squad to remove any evidence of the project. While it is not explicitly stated, the Deleter was in fact James Pierce, the squad's communications expert. The presence of Samus derails James' mission, though he does manage to kill several members of Adam's squad before he himself was found dead in the Bioweapons Research Center: it can be surmised that he tried to eliminate MB, but failed. An unnamed scientist who cleans the Metroid and Ridley's DNA off Samus is implied to be a member or operative for the group. Additionally an unnamed GF colonel who orders MB's destruction and attempts to force Samus to handover Madeline Bergman using the fact she is an outsider to force her to comply is implied to either work for or a top ranking member of the group and may have been the one responsible for sending the Deleter to eliminate Adam and his team before they could uncover and expose their bio-weapons research as he is a member of the Galactic Federation military. The actions of Samus and Adam's heroic sacrifice put an end to their bio-weapons research on the Bottle Ship, but their secret bio-weapons research and Metroid breeding program continues on the B.S.L. research station until it is overrun by the X parasites. In "Fusion", Samus discovers the continued bio-weapons research and learns that they foolishly plan to capture the X parasites and the SA-X for the bio-weapons research, and crashes the station into the planet SR388 with the help of her ship's AI, which was based on Adam Malkovich.
