Layton continued to ink and work on covers for titles such as "The Incredible Hulk", "Captain America", "Power Man and Iron Fist", and "Micronauts". In September 1982, he launched one of Marvel's first limited series, writing and drawing the four-issue "Hercules: Prince of Power". Its success spawned a four-issue sequel in 1984 and a 1988 graphic novel (#37 in the "Marvel Graphic Novel" series) - "Full Circle". Around this time, he designed the highly successful "Marvel Secret Wars" toy line for Mattel, which formed the impetus behind the 1984 "Secret Wars" event. Layton was one of the inkers on "The Amazing Spider-Man Annual" #18 (1984) which featured the wedding of Spider-Man supporting characters J. Jonah Jameson and Marla Madison in a story written by Stan Lee.
