Campbell draws with an animator's sense of pose and expression, all clean curves and confident line. Gen 13 and Danger Girl made his name in the nineties, and his variant covers have since become some of the most collected on the stands.
Few artists have shaped what a superhero looks like on the page as directly as Jim Lee. His early-nineties X-Men work, all dense crosshatching and coiled anatomy, became a house style that later artists still work against. He left to co-found Image Comics and WildStorm, then became one of DC's defining figures on Batman: Hush and Justice League.
Romita builds figures from blocky, weighted shapes that land with real force. Across four decades he has drawn most of the Marvel line, from Amazing Spider-Man and Daredevil to Thor and Uncanny X-Men, plus Kick-Ass with Mark Millar and a run on Superman.
