The Destroyer was an enchanted automaton controlled by Odin to guard his vault on Asgard. When the throne of Asgard was upsurped by Loki, the Destroyer was sent to Earth to kill the exiled and depowered Thor. The Destroyer found Thor in New Mexico and seemingly killed him, despite the efforts of Sif and the Warriors Three. However, Thor's selfless efforts evacuating the area of innocents made him worthy of his powers again, which allowed him to fight the Destroyer and render it inoperable. The disabled Destroyer was confiscated by S.H.I.E.L.D. and was reverse-engineered to create a powerful laser weapon.
