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.
Megamind: The Button of Doom
For their first day on the job as the new protectors of Metro City, Megamind (Will Ferrell) and Minion (David Cross) are selling off their gadgets from their evil lair to the citizens for good purposes. All of their items get sold (except for the Death Ray which Megamind used to "kill" Metro Man in the original film). As for the De-Gun, Megamind's weapon of choice used for a number of different destructive functions, it gets sold to a boy named Damien, who accidentally uses it, in its dehydration mode, on his mother and turns her into a cube. After the auction is over, Megamind reveals a suit he created that copies all of Metro Man's powers, which he will wear to protect Metro City.
