Plastoid was a type of material used in the armor worn by Darth Vader, a Dark Lord of the Sith. When Luke Skywalker burned Vader's armor on Endor, only the charred and twisted remains of the partially molten helmet, along with ashes and small pieces of metal and plastoid were left behind in the funeral pyre. Stormtrooper armor was made of a plastoid composite.
