TARDIS

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

In some parts of the multiverse, sentient TARDISes are known to exist. None have appeared in HQ yet, but it is probably only a matter of time.

TARDISes in the PPC
When the macrovirus epidemic swept through HQ in 2008, each pair or trio of uninfected agents in the field was given a TARDIS, duplicated by DoSAT, to serve as a mobile response center (which has been cited as a key component of Cycle Theory). They were coordinated by the Corkscrew Cattail. Prior to this point, the only TARDIS known to be in HQ belonged to Agent Morgan, who was reportedly quite annoyed by this development. And by being killed. Again.

Since the end of the emergency, to the relief of those worried about Cycle Theory, it seems most agents have returned to their response centers. Active TARDISes in the PPC now seem to be limited to actual Time Lord agents such as Agent Morgan and The Fisherman.

The Cloister Bell is the TARDIS equivalent of the BEEP! that the console uses to alert agents to impending missions.
