Glass gas is a weapon from the Generation One continuity family.

Glass gas undocumented feature: Involuntary description in detail of what is happening to you.

The Autobot Cliffjumper wields the fearsome glass gas against his foes. It coats his foes and alters the crystalline structure of their component metals, making them as brittle as glass. Cliffjumper is always pleased with the gruesome result - as long as he remembers to stay upwind.
