|~ Jasper Sitwell and Agent Coulson about the Destroyer|
While not as powerful as the comic version, nonetheless, the Destroyer is one of the most powerful non-living weapons in the MCU. The Destroyer operates at the behest of whomever holds Gungnir, the Asgardian ruler's spear, and can therefore be used for good or for evil depending on who sits on the throne. It can also therefore be stopped by an attack on its vulnerable master. The Destroyer was programmed solely for battle and destruction.
- Strength: The Destroyer's large size and construction gives it a formidable physical power, enough to bat away a car hurled at it with apparent ease and swat Thor back several feet with one hit (although Thor was temporarily human at the time).
- Durability: The Destroyer was constructed of alien materials that makes it highly resistant to damage. Even when pierced by an Asgardian lance it was able to continue functioning and remove it from its body and showed no signs of damage from it.
- Energy Blast: The Destroyer contains Odinforce that can be unleashed through an aperture in its head. When it does this, part of the facial structure retracts downward into the lower face and the energy discharge lances out the orange-white beam. The touch of this beam was enough to blast a car to pieces or vaporize a living being. At full power, it nearly devastated half of a town.
- Retrograde Positioning: The Destroyer is able to move its armor pieces so that it faces the opposite way without turning around; its back side becomes its front side and vice versa. This was used when Lady Sif drove a lance through its back and the Destroyer positions itself to blast her.
