Question (comics)
The Question's specialized belt buckle, which releases a binary gas that binds his mask to his skin and temporarily recolors his garb and hair, is similar to that of the Spider-Man villain Chameleon. In his initial appearances, which were drawn by Steve Ditko, the Chameleon had used a device in a belt buckle which emitted a transformation-enhancing gas. The binding element is adjusted to Sage's specific body chemistry.
