The Incredible Hulk #256 (Marvel, 1981)

The Israeli superhero Sabra makes her first cover appearance and her first full appearance ever after only a previous single-panel cameo. After this full issue introduction, the character would go on to appear next in Marvel Super Hero Contest of Champions #2 in 1982. A version of the character (as another product of the Black Widow/Red Room program) appeared in Captain America: Brave New World in 2025. This iconic cover is a true knockout and a rare example of a character making a full debut on a cover, particularly in such a bold image -- and one where all the hallmarks of the great John Romita Jr.'s classic peak-period style are on full display.
