Anzor's TARDIS
From Tardis Wiki, the free Doctor Who reference
Anzor's TARDIS was the transport of the renegade Time Lord and old childhood enemy of the Doctor. Anzor used a Type 60 TARDIS. (PROSE: Mission to Magnus)
It was a later model than the Doctor's TARDIS, and Anzor used that superiority to lock the Doctor's TARDIS into orbit around Magnus.
