Susan (Dr. Who and the Daleks)
From Tardis Wiki, the free Doctor Who reference
Susan, also known as Suzy, was a fictional version of the Doctor's granddaughter Susan, created by the Doctor himself. She, along with a fictional version of the Doctor, served as decoys to distract the Five O'Clock Shadow while the real Doctor piloted his TARDIS to safety. (PROSE: The Five O'Clock Shadow)
