(TV: Time Crash)
 * The first eight Doctors also time rammed their TARDISes against the Master's TARDIS in order to defeat him in a pocket dimension. (AUDIO: The Light at the End)
 * The Tenth Doctor time rammed an imitation of the TARDIS in the Time Vortex in an attempt to save Cindy Wu. (COMIC: Sharper Than a Serpent's Tooth)
 * The Daleks also used a time ram against a factory default TARDIS and the Eighth Doctor's TARDIS when its defences were removed. (AUDIO: Tangled Web, X and the Daleks)
 * The Daleks launched a temporal bomb in the origins of Gallifrey, which the Doctor assumes is revenge for his own attempt to wipe out the Daleks in their past. (TV: Genesis of the Daleks)
