Namor, the Sub-Mariner #47

In "SeaQuest," Namor and his allies battle the alien Xlyym’s mind control to free Triton and Trieste, only to find themselves trapped in a powerless submarine sinking into the depths of the Marianas Trench. Written by Glenn Herdling and illustrated with gripping detail by Geof Isherwood—whose dynamic interior art and cover pencils bring the underwater tension to life—this 1994 Marvel classic delivers a claustrophobic, high-stakes dive into the ocean’s darkest reaches.
