Diceman was a short-lived British comic which ran for five issues in 1986. It was a spin-off from 2000 AD and was devised by Pat Mills, who also wrote almost all of the stories. It was edited by Simon Geller, but purported to be edited by a monster called Mervyn. The stories were designed to be played like gamebooks. Each issue contained two or three such stories and was published every two months.

Patrick Eamon Mills is an English comics writer and editor who, along with John Wagner, revitalised British boys' comics in the 1970s, and has remained a leading light in British comics ever since. He has been called "the godfather of British comics".
