Battle TARDIS (Stop the Clock)
After escaping after being captured by the Time Lords in opposition to the Doom Coalition, the Eleven took Helen Sinclair as a hostage, and hijacked a lone Battle TARDIS, which he piloted to the Capitol.
Caleera, upon discovering how much Padrac had ruined and manipulated her life, gave Helen some of her powers as the Sonomancer, and Helen was able to fight against the Eleven and hold him down. She was even able to resist a direct blast from the Eleven's weapon.
Helen used the Battle TARDIS to destroy the Resonance Engine, saving the universe. (AUDIO: Stop the Clock)
The Battle TARDIS was heavily damaged, and in the words of Helen "falling apart," when it finally met its end by crash landing on Rykerzon. (AUDIO: World of Damnation, Sweet Salvation)
