Mutants are the subject of a number of stories in the Judge Dredd science-fiction series published in British comics 2000 AD and the Judge Dredd Megazine. Mutants are genetically-flawed, physically deformed people who are the subject of prejudice and apartheid in the 22nd century. Although they have appeared in Judge Dredd since the strip's earliest stories in 1977, a major story arc beginning with "Mutants in Mega-City One" in June 2007 and ending with "Tour of Duty" in July 2010 dealt specifically with their struggle against apartheid in Dredd's city, Mega-City One.
