Ytraxorian Reality Gun

A Ytraxorian Reality Gun was a name coined by Torchwood Three for a weapon acquired from a Ytraxorian who appeared in the Hub in 2009. It was capable of transporting a target randomly through time and space.

Oscar Lupé was hit by the gun when it was being transported from Britain into CIA custody, causing him to disappear. (PROSE: The Men Who Sold the World)
