The Seventh Doctor claimed to have delivered Genghis Khan, describing him as "a sweet baby." (PROSE: Tragedy Day)

When the Master claimed he wanted to rule people "for their own good", the Third Doctor wondered if he had heard Adolf Hitler or Genghis Khan say the same thing. (TV: The Dæmons)

The Master once lied and told Chang Lee that the Doctor had been Genghis Khan in one incarnation. (TV: Doctor Who)

The Doctor's TARDIS once withstood an attack from the hordes of the Genghis Khan, as recounted by the Sixth (AUDIO: City of Spires) and Ninth Doctors. (TV: Rose)

The Eleventh Doctor was uncertain if it had been Al Capone or Genghis Khan who had told him that villains wanted records of exactly how bad they'd been. (PROSE: Borrowed Time)

Genhis Khan also existed in Pete's World, where he was cited as an inspiration by John Lumic alongside Adolf Hitler and Machiavelli as people who "got what they wanted in spite of the little people". (PROSE: Lumic)
