Junk TARDIS

The Junk TARDIS was a makeshift TARDIS created by the Doctor and Idris (the embodied matrix of his TARDIS) to reach his own TARDIS, which had been hijacked.

They constructed it out of bits of TARDISes from the Bubble universe's junkyard, a task which Idris called "impossible". The components were from TARDISes that had traveled through the Bubble universe rift and been consumed by House (with their Time Lords likewise being killed by House). The TARDIS consisted solely of a console (with time rotor) and three walls. It was lacking a proper shell which the Doctor stated would be very dangerous to travel without.

Unfortunately, the Junk TARDIS was not able to draw enough power from the rift energy in the Bubble Universe. The only way it was able to function was due to the Doctor's TARDIS personified in Idris, who powered the Junk TARDIS for him, as well as operated the telepathic circuits.

It was highly unstable in flight, but once the Doctor's TARDIS' shields were down, it managed to materialise in an archived control room. It materialised in the same spot Nephew was in, killing him. The Junk TARDIS was lost when the archived control room was deleted by House. (DW: The Doctor's Wife)
