TARDIS

The TARDIS (an acronym for Time and Relative Dimension in Space) is a time travel technology which has the ability to materialize as a camouflaged object in the reality targeted. The pilot of a TARDIS enters through a set of doors in the camouflaged exterior, to a control and living area which has greatly expanded dimensions compared to the outside.

In an alternate reality, a TARDIS was deposited in the 23rd century. In this reality, Emperor Vandar tracked the TARDIS when it arrived in his space-time, and captured its occupant, and took the vehicle to his trophy room. This particular TARDIS was disguised as a London police call box, and was present when he captured and entertained Captain Jame T. Kirk and landing party, who had been captured along with a number of Legionnaires from yet another reality. 


 * The upcoming Star Trek: The Next Generation—Doctor Who crossover, Assimilation², will also feature the TARDIS, and it is shown on the first issue's cover. The fact that the TARDIS captured by Vandar was disguised as a police call box suggests that it was the one belonging to, as the Doctor's is permanently frozen with that particular camouflage. There is the possibility, however, that Vandar had captured another TARDIS that had just happened to take the same camouflage appearance.
