Anti-Gravity Gun (Earth-6531)

The Anti-Gravity Gun (AA Gun), is a series of weapons created by the Tinkerer with combined Parademon technology and the remnants of Ultron's technologies.

History
The Tinkerer created the Anti-Gravity Gun by orders of the Vulture, and promptly sold in the black market across the globe.

Four criminals, all masked with the faces of some members of the Justice League, purchased one of these weapons, using it to destroy cashiers at the Queens Community Bank. They were stopped by the vigilante Spider-Man, who took three of them with ease before the fourth one drew his AA gun and shot the hero.

While Spider-Man fought against them, the criminal using the weapon attempted to shoot him again, causing the shot to be directed at a nearby store, where a civilian named Delmar Madera, a neighbor of Peter Parker, was killed. Two of the robbers were ultimately able to escape, but the gun was apprehended by Spider-Man.

One night later, Shocker, one of Toomes' henchmen, attempted to leave their operations, Adrian attempted to use the AA gun against him, but ultimately chose another to kill him.
