Irken teleporters

Irken teleporters prove capable of seamlessly transporting living beings to different locations; specifically, one of Zim's teleporters in his base is able to beam people up to his space station orbiting Earth. It is highly possible that the several other teleporters seen are meant for transportation to other places also, besides his station. However, the teleporters do seem susceptible to sabotage, in that Zim once prevented Gaz and Dib from leaving in this way by cutting the power—and he also prevents the rest of the alliance from coming up to the space station from his base in the "Dimension" saga. Nevertheless, the teleporter on board the station ends up being Sonic's only method of getting back to the planet surface (seeing as a barrier is now in place, surrounding Earth—courtesy of the Nazca Lines' secret weapon).
