Unibeam (Yost Universe)

The Unibeam is the ultimate weapon of the Iron Man armor used by Tony Stark.

Uses
The unibeam is used as a final weapon of choice. It can fire a very long repulsor beam blast from the armor's chest within a hundred mile radius.

However, it requires a large amount of energy to power up the unibeam otherwise if too much energy,it might cause the suit to shut down and slowly recharge.

History
Its history was largely unknown but it is stated that Tony Stark had first discovered the unibeam possibly tested it if his chestpiece would fire a large repulsor beam blast.

He then integrated them into all of the Iron Man armors including the Mark I.

On a number of occasions, Tony often used the unibeam to finish off enemies and aliens.

Background Information
The unibeam's color is bluish color instead of yellow in other versions of that weapon.

It is very unique and different weapon of choice but requires a large amount of energy to do it.
