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.
Villains United
The central revelation of the book is that Mockingbird is actually Lex Luthor and that the Luthor who organized the Secret Society is an "imposter" (in reality, Alexander Luthor, Jr.). Mockingbird/Luthor reveals that he chose those six individuals because each had different knowledge and experience that could be used to oppose the Society: Catman, for his knowledge on Batman's villains; Deadshot, for his knowledge on the remaining Suicide Squad members; Parademon, for his experience living on Apokolips; Ragdoll, because he grew up as a "nephew" to the members of the Injustice Society; Scandal, because she grew up with Vandal Savage and his associates; and Cheshire, for her knowledge on the villains of the Teen Titans. Mockingbird/Luthor reveals to Scandal that he never placed the families of the Six in danger and disbands the team. Also notable is the Society Luthor's apparent murder of Pariah, a character from the original Crisis.
