Gravity Stopper

The Gravity Stopper is another of H.D.S.V.A.D.L.'s many ray weapons. This large cannon fires a blast of zero-point energy at targets, causing them to lose all weight and be suspended in the air. Wes Weasely sold a Gravity Stopper cannon to Dr. Robotnik in the AoStH episode Birth Of A Salesman and even threw in two pairs of Self-Gravity Boots so that Scratch and Grounder wouldn't be affected by the device.

Scratch and Grounder attacked Sonic and Tails with the Gravity Stopper and kept them suspended in the air so they could gloat over their defeat. Although Sonic couldn't run away, Tails tried to fly them away, prompting Scratch to take off his Self-Gravity Boots so he could catch them. Finding himself helpless, Scratch told Grounder to shut off the Gravity Stopper. Grounder did so, and Scratch fell on top of the Gravity Stopper and Grounder, wrecking them all.
