Superhero fiction fiction. In 1960, DC banded its most popular heroes together in the Justice League of America, which became a sales phenomenon. Empowered by the return of the superhero at DC, Marvel Comics editor/writer Stan Lee and the artists/co-writers Jack Kirby, Steve Ditko and Bill Everett launched a new line of superhero comic books, beginning with The Fantastic Four in 1961 and continuing with the Incredible Hulk, Spider-Man, Iron Man, Thor, the X-Men, and Daredevil. These comics continued DC’s use of science fiction concepts (radiation was a common source of superpowers) but placed greater emphasis on personal conflict and character development.
Power Comics integrate elements of American superhero comics into mainstream British comic publishing, motivated by the huge success of Stan Lee's line of Marvel Comics in the USA. Besides reprinting many of Marvel's most popular series such as Spider-Man and the X-Men, there was also an attempt to create a home-grown British superhero: firstly with Johnny Future, who appeared in "Fantastic" prior to its merger with "Terrific"; and subsequently with 'Tri-Man', who appeared in "Smash" after its merger with "Fantastic". As well as drawing heavily on Stan Lee's creative output, Power Comics also attempted to emulate Lee's chatty style and community building
