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
Lord Wily can be seen as the primary antagonist of the Battle Network franchise. He himself appears as the main villain of "Mega Man Battle Network", "Mega Man Battle Network 3" and "Mega Man Battle Network 6". He manipulates Sean Obihiro into leading the NetMafia Gospel in "Mega Man Battle Network 2", and his son Dr. Regal is the main villain of "Mega Man Battle Network 4" and "Mega Man Battle Network 5". He becomes jealous when his robotics research is pushed aside in favor of Tadashi Hikari's breakthroughs in network technology, and devotes his life to destroying network society. "Battle Network 6" reveals that, for a time, Wily had put aside his thirst for revenge; however, the death of Baryl's father caused him to reconsider.
