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.
Brotherhood of Evil
With Madame Rouge's daughter Gemini now a member, the group reunited with Phobia, Mallah, and Brain and joined the Secret Society of Super Villains, under the command of inner circle member Deathstroke. Deathstroke had the group acquire the mass murdering chemical monster Chemo for the Society and in "Infinite Crisis" #4, dropped the monster onto the city of Blüdhaven. Murdering several million people, the Brotherhood became the most wanted villains in the DC Universe for their act of mass murder. Furthermore, Warp was recruited by the villainous Doctor Psycho to free the murderous Doomsday for the Society as part of the group's final endgame against Earth's heroes.
