H.D.S.V.A.D.L.

The H.D.S.V.A.D.L. company (Handy-Dandy Super-Villain Appliance Distributors, Limited) is a corporation that dabbles in the production and sale of various gadgets and weapons to aspiring super-villains. They have built and sold a large variety of gizmos, including the Darkinator, the Freeze Banger, the Gravity Stopper and the De-Atomizer. Wes Weasely is one of their best spokesmen, as was proven when he sold several weapons to Dr. Robotnik without living up to the company's money-back guarantee. H.D.S.V.A.D.L. were also the ones who sold several defense systems to Robotnik for his Pinball Fortress, such as its impenetrable door (which had a slight rust problem).
