In 'Thor', Odin had a 12' tall armored robot called 'The Destroyer' guarding the weapons vault. The Destroyer is composed of overlapping and articulating metal strips. When it's about to attack it emits a distinctive whirring, spooling up sound as it starts glowing yellow from the inside and its face panels open. Its primary weapon seems to be some kind of yellow disintegrating type force beam that it shoots from its 'face'. Has there been any information disclosed about what its power source may be?
This question is focused on The Destroyer's technology/power source as presented on screen unless they're planning to introduce the Fourth Host of Celestials and the Skyfather gods (e.g. Zeus, Osiris, Shiva, etc.)
