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.
