The Freeze Banger is a freezing ray weapon built and sold by H.D.S.V.A.D.L.. Dr. Robotnik bought two of these weapons from Wes Weasely in the Adventures of Sonic the Hedgehog episode "Birth of a Salesman".
Scratch and Grounder tried to ambush Sonic with Freeze Bangers, but Sonic avoided their blasts and the robots froze each other. Sonic then ran around the two robots so fast that he set the road on fire, melting not only the ice that Scratch and Grounder were trapped in, but Scratch and Grounder themselves.
The Freeze Banger was soon afterwards used as a component of the Super Stupendous Tremendous Horrendous Hedgehog-Catching Vanquisher.
The Freeze Banger was remade and used to stop Dr. Doofenshmirtz from using his Amnesia-inator.
