Beginning with issue #169, Strange Tales was renamed to Doctor Strange. Expanded to 20 pages per issue, the Doctor Strange solo series ran 15 issues, #169-183.Roy Thomas wrote the run of new stories, joined after the first three issues by the art team of penciler Gene Colan and inker Tom Palmer.
Colan drastically altered the look of the series, as Thomas recounted: "…he had his own view of what these other worlds should look like. Everyone else sort of copied Ditko's versions of those extra dimensions, which were great and wonderful. When Gene came on, he didn't feel a real rapport with that, I guess, so his extra dimensions tended to be just blackness and smoke and things of that sort… Sometimes it was a little strange for a dimension Doc Strange had been to before to look different when drawn by Gene, but nobody complained."[
