Behind the Scenes
Doctor Omega is the main character of the 1906 French science fiction novel Le Docteur Omega by Arnould Galopin, which fell in the public domain in 2004. After Doctor Who nonfiction writer Jean-Marc Lofficier discovered the character and noticed the similarities between him and the First Doctor, him and his wife published an English translation of the book. They gave it a new cover, similar to that of Chris Achilleos' for Doctor Who in an Exciting Adventure with the Daleks, with an introduction by veteran Who writer Terrance Dicks. Lofficier added lines suggesting that the novel told adventures of the Doctor shortly before An Unearthly Child, with the Doctor having taken a brief leave of absence from his grand-daughter, Susan Foreman.

Doctor Who writers John Peel and Andrew Skilleter wrote new adventures for him, giving a spaceship with time travel capacities, and with the art staying close to promotional pictures of William Hartnell.

The Lethbridge-Stewart series of publications seems to imply that Doctor Omega is the in-universe version of the Hartnell era of Doctor Who with its Dalekmania being replaced by the Kelptonmania and Hartnell by an actor actually considered by the BBC at the time.
