The Avengers #263

In "What Lurks Below?", the Avengers take on a mysterious deep-sea mission when they recover a strange cocoon from Jamaica Bay—containing the dormant form of Jean Grey, long believed lost. With Sub-Mariner newly joined and tensions rising, Captain America, Wasp, and Black Knight must convince their government liaison, Raymond Sikorsky, that Namor deserves full membership, all while navigating personal moments and unseen dangers beneath the waves. Roger Stern’s writing and John Buscema’s dynamic art, enhanced by Tom Palmer’s inks and Christie Scheele’s colors, bring this pivotal moment to life, with a cover by Buscema and Palmer capturing the eerie mystery of the deep.
