A unibeam is an offensive attack built into the armors of Iron Man. The robot Ultron, which was designed by Iron Man, also has the ability to fire a unibeam. It is unknown if Iron Man built it into the robot or it figured out how to do it itself. It is a particle beam weapon in the chest piece; can repel physical and energy-based attacks, traveling as a single stream or as a wide-field dispersal. It is extremely destructive and power. Iron Man is also deadly accurate with the beam and can hit targets flying through the air.
