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.
List of Mega Man characters
Lumine is the main antagonist of "Mega Man X8". Due to being a new generation Reploid, he can transform into other Reploids. Lumine is introduced as the director of the Jakob project, the Orbital elevator in the beginning of X8. He was soon kidnapped by Vile, due to his knowledge of the elevator. After defeating Sigma (originally thought to be the instigator of the events of the game once more) on normal or hard mode, Lumine is revealed to have been manipulating a weakened Sigma this time around, though he really means that he is essentially Sigma himself, and is carrying out his plans. He knows that Sigma could not do what he did in the whole series forever. He goes onto claim that this was Sigma's final death and that would be unable to return.
