Cardinal Ollistra owned a Battle TARDIS, which she used to travel during the Last Great Time War.

She used it to reach Synthesis Station, where an open door allowed it to be infested by Vashta Nerada. (AUDIO: Day of the Vashta Nerada) Later, the Doctor's TARDIS was loaded onto her Battle TARDIS for transport to the Tenacity system. (AUDIO: Echoes of War, The Conscript)
