Roy Thomas joined the Marvel Bullpen as a writer and editor under Stan Lee, scripting key runs of nearly every title of the time: Amazing Spider-Man, Avengers, Daredevil, Doctor Strange, Sub-Mariner, Thor, X-Men and more. He wrote the first 10 years of Marvel's Conan the Barbarian and Savage Sword of Conan; and launched such series as Defenders, Iron Fist, Invaders and Warlock. At DC, he developed All-Star Squadron, Infinity Inc. and related titles, proving instrumental in reviving the Golden Age Justice Society of America. Thomas later became editor of Alter Ego, a magazine devoted to comic-book history, and co-scripted the sword-and-sorcery films Fire and Ice and Conan the Destroyer. Dan Adkins (1937-2013) worked on comic books and science-fiction magazines from an early age; as the Silver Age of comics dawned, he joined the Wally Wood Studio as Wood's assistant, their collaborations including stories in such titles as Creepy and Eerie. Adkins arrived at Marvel in 1967 and worked primarily as an inker on an array of titles, including an extensive run on Conan the Barbarian. He also penciled the adventures of Doctor Strange, Ka-Zar and others.

Also famed for his cover paintings, Adkins was inducted into the Joe Sinnott Hall of Fame in the Inkwell Awards of 2019. In 1976, Ross Andru (1927-1993) made comic-book history by penciling the first large-scale intercompany crossover, Superman vs. the Amazing Spider-Man, having spent years illustrating both characters in various titles. He also made Marvel history in Marvel Feature, drawing the Defenders' first appearance. At DC, he spent nine years collaborating with Bob Kanigher on Wonder Woman. With Marv Wolfman and Mike Esposito, he co-created Vigilante (Adrian Chase). Don Heck (1929-1995) worked for Harvey, Quality, Hillman and other publishers before arriving at Atlas Comics, later Marvel, where he penciled and inked stories for virtually every genre: crime, horror, jungle, romance, war, Western and more. With Stan Lee and others, he launched Iron Man, his supporting cast and his early rogues gallery -- including the Black Widow, Hawkeye and the Mandarin.

He also succeeded Jack Kirby on Avengers. At DC, his artwork appeared in Justice League of America, Flash, Wonder Woman and other titles.
