Sharon (Doctor Who)
Sharon (last name not given) 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 Fourth Doctor. The canonicity of the comic strips, like other Doctor Who spin-off media, is unclear.
Sharon was introduced in Doctor Who and the Star Beast, which ran in issues #19-#26 of Doctor Who Weekly (as it then was), written by Pat Mills and John Wagner, and drawn by Dave Gibbons. She was a secondary school student living in the city of Blackcastle, England. She was the first non-white companion, albeit not on television.
