TARDIS

A TARDIS is a time machine originally from Doctor Who. Its name is an acronym for "Time And Relative Dimension In Space." It is a multidimensional vehicle whose interior can be customized. It's exterior changes depending on the time and place it is in, so it may blend in with it's surroundings. Sometimes the device that facilitates this change breaks and the TARDIS will remain looking the same way until the problem is fixed.

When the macrovirus epidemic swept HQ, each pair or trio of uninfected Agents was given a TARDIS to serve as a mobile Response Center. They are coordinated by the Corkscrew Cattail.
