Repulsor Beam (Marvel Anime)

The Repulsor Ray is a particle beam weapon created by Tony Stark aka Iron Man.

Uses
It can be used to provide jet speed to the Iron Man armor's flight engines to makes it fast.

It can blast through anything or anyone within a mile away from where Iron Man is standing or flying on.

History
The first repulsor ray of the Iron Man armor is the Mark I's arm-wristed flamethrowers that were quite effective on the terrorist forces in Stark's escape.

After Stark returned to America, he created the repulsor ray as the main weapon of the Iron Man Mark Nos. and Special armors he developed over the years.

When Stark came to Japan, he even gave the schematics of the repulsor ray weapon to the Japanese Defense Force who then built their own Ratsetsu armor, a samurai-type armor, piloted by Sakurai.

However, the Zodiac came to possess the repulsor ray weapons through Kuroda and the stealing of the Iron Man Dio armor and were using it against Tony Stark. But Stark defeated them all including Kuroda (in his bigger Ratsetsu armor) due to Stark's knowledge of those weapons he built.

After his job is done in Japan, Tony Stark then went back to America along with those armors he brought along.
