The TARDIS is NOW!

The Doctor's TARDIS — sometimes called the Ship by the First Doctor, before then the Box, and most often known simply as the TARDIS (PROSE: Time and Relative, COMIC: Food for Thought) — was the Doctor's primary means of transport. It was capable of travelling through space and time. The Doctor voyaged in his vessel from the Big Bang (TV: Terminus, Castrovalva, AUDIO: Slipback) to the end of the universe in the year 100 trillion. (TV: Utopia).Other Time Lords frequently characterised the Doctor's TARDIS as woefully out-of-date. (TV: The Time Meddler, The Claws of Axos, The Ribos Operation) Indeed, by at least the time of the Doctor's fourth incarnation, if not much earlier, the model — called a "Type 40" — had been pulled from general service on Gallifrey. (TV: The Deadly Assassin, The Invasion of Time)

The craft was prone to a number of technical faults, ranging from depleted resources (TV: An Unearthly Child, The Wheel in Space, Vengeance on Varos) to malfunctioning controls (TV: The Edge of Destruction) to a simple inability to arrive at the proper time or location. (TV: The Visitation, Attack of the Cybermen, The Eleventh Hour, Victory of the Daleks, The Girl Who Waited and many others) However, because the TARDIS was a living being, these "faults" may instead have been at least partially attributed to the manifestation of the Ship's free will. Indeed, the TARDIS herself once told the Eleventh Doctor that she may not have always taken him where he wanted to go, she had always taken him to where he needed to go. (TV: The Doctor's Wife)

As the centuries passed and all of the Doctor's companions came and went, his faithful TARDIS remained his constant companion. They shared an unbreakable bond, and the Doctor came to feel that in the end, it was just him and his TARDIS. (AUDIO: The Girl Who Never Was, TV: The Doctor's Wife) The Doctor and his TARDIS were so close, that, in an alternate timeline, his TARDIS eventually became his final resting place, containing the Doctor's timestream.
