With their make-up and costumes, the Doctors took on the personas of comic book-style characters: The Starchild (9th Doctor), The Demon (10th Doctor), The Spaceman or Space Ace (11th Doctor) and The Catman (12th Doctor). No. 9 became the "Starchild" because of his tendency to be referred to as a "starry-eyed lover" and "hopeless romantic." The "Demon" make-up reflected No. 10's cynicism and dark sense of humor, as well as his affection for comic books. No. 11's "Spaceman" make-up was a reflection of his fondness for science fiction and his supposedly being from another planet. No. 12's "Catman" make-up was in accordance with the belief that he had nine lives, because of his rough childhood on Gallifrey.
