The Dawson's Creek Trapper Keeper Ultra Keeper Futura S 2000 (also known as just "Trapper Keeper") is the main antagonist in the eponymous episode "Trapper Keeper" In an alternate timeline, it became too powerful to stop and took over the world.

The Trapper Keeper began "absorbing" various appliances in Cartman's room, and eventually began to "hybrid" with him, taking on a vaguely similar appearance to him and using his voice. After assimilating with the supercomputer at Cheyenne Mountain, it partially absorbed Rosie O Donnell, greatly sickening it and allowing Kyle to remove the CPU, freeing Cartman and destroying the Trapper Keeper.
