"The Amazing Mr. X" was a strip that ran in The Dandy, back when that comic ran adventure as well as humour material. The strip, drawn by Jack Glass, delivered the exploits of the dashing Les Manners, alias Mr. X, a masked-and-caped crime-fighter who was so strong he could tear the tails off aeroplanes and stuff. The character first appeared in issue 272, dated 5 August 1944; his adventures lasted for only 14 issues, although he made another appearance in a Dandy annual in 1962, drawn by Dudley D. Watkins.
Morris Heggie, who edited The Dandy from 1986 to 2006, described Mr. X as "The closest we've ever had to a super hero". However, he added that "His arch nemeses weren't glamorous.... He would chase people who stole lead from roofs and other small time crooks."
Mr. X Was one of several superhero characters revived for "Retro Active", a partially animated strip in the digital incarnation of The Dandy which launched in December 2012.
