Isabelle "Izzy" Sinclair is a fictional character who appeared in the Doctor Who Magazine comic strip based on the long-running British science fiction television series Doctor Who. She was a companion of the Eighth Doctor. Izzy was born on October 12, 1979 (the same day that the first issue of Doctor Who Weekly was published). However, she did not know where she was born, nor did she know who her biological parents were. She was adopted by Les and Sandra Sinclair, but because of her unknown ancestry, chose to call herself Izzy S (for "Izzy Somebody") instead. Izzy was first introduced in End Game, which ran in issues #244-#247 of DWM, written by Alan Barnes and drawn by Martin Geraghty, where she was a 17-year-old science fiction fan and amateur paranormal investigator who lived in the town of Stockbridge, England. She was also a friend of Maxwell Edison, a UFO enthusiast who had encountered the Fifth Doctor several years before.

Izzy had left Earth without telling her adoptive parents, but that did not concern her much as she was trying to escape what she felt was a too-mundane life. As a result, she revelled in the experience of travelling with the Doctor, even though it was usually dangerous. However, her vivacious and trusting nature eventually had tragic consequences. When the TARDIS was swallowed by a gigantic snake-like spacecraft called Ophidius, Izzy and the Doctor met Destrii, an amphibious alien with the characteristics of a humanoid fish. Destrii was being pursued by the group of aliens that controlled Ophidius, and gained Izzy's confidence only to switch bodies with her to evade capture. When Destrii (in Izzy's body) was apparently disintegrated, Izzy had to deal with the possibility that she
