In the 2008 film, the repulsors are a form of propulsion and (as hand units) steering jets, though they can be used offensively. They have been referred to as being magnetic, a blast of charged particles, and as a force beam. The repulsors originated as a hand attachment, but have since become the armor's most important standard armament. The defining abilities of Stark's armor are the jets situated in the boots and the repulsors situated in the gauntlets. Earlier versions of the armor could also fold virtually flat, allowing Stark to store them in his bullet-proof briefcase. Furthermore, they typically have multiple power sources including a secondary solar energy collection function in the event that conventional-recharging methods are unavailable. Every suit has a self-contained environment, assorted onboard weapons systems, enhanced strength, flight, and various communications arrays and sensors (such as radar and radio). They are made of incredibly-strong, fictional materials bolstered by a force field. Stark's suits are each unique in design and purpose.
