A repulsor beam is an offensive attack built into the armors of Iron Man. It is his most iconic attack. They are a particle beam weapon in the palm gauntlets; can repel physical and energy-based attacks, traveling as a single stream or as a wide-field dispersal. They can be extremely destructive, allowing Iron Man to blast through walls of government buildings. Iron Man is also deadly accurate with the beams and can hit small targets flying through the air. It is possible, though not specified, that Iron Man uses the same or similar technology to fly with.
