Namor, the Sub-Mariner #23

Namor, the Sub-Mariner #23 brings a genuinely unsettling cover from John Byrne, who both penciled and inked the image: a massive, oozing green-and-yellow arm thrusts upward from a tangle of sickly vegetation, its dripping fist radiating a burst of toxic-looking energy, while a bare-chested Namor recoils and braces for a fight against whatever monstrous force is rising before him. The tagline "…Like Unto a Thing of Iron" promises something formidable lurking beneath that grotesque exterior. With the Fantastic Four's 30th anniversary badge adorning the corner, this 1992 issue sits at an intriguing crossroads of Marvel history.
