|Real Name||Repulsor Beam|
|Powers and Abilities||Powerful Energy Attack|
|Family and Friends||Iron Man Armor|
The robot Ultron adapted the repulsor beams into its design.
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 powerful enemies.
Iron Man has a more powerful beam built into his chest called the unibeam. This is a more powerful attack though it drains more energy so it is used less often.
It is possible, though not specified, that Iron Man uses the same or similar technology to fly with.
Its early history was largely unknown but it is stated that Tony Stark had created the Repulsor Beam as his main weapons to the Iron Man armor he built.
As he built Ultron, he added the Repulsor Beams, Unibeam, and other advanced weaponry on it
When Ultron found Iron Man and the Avengers' children in their hiding location, Tony had clashed with his creation as the children escaped. But Ultron had the upper hand and defeated its creator and destroyed the armor.
In the desert, Ultron used his Repulsor Beams and Unibeam on the Hulk, but the green brute had resisted them and destroyed the machine in the process.
