Marvel Team-Up #9

The cover of this May 1998 Marvel Team-Up tells you everything you need to know: Namor the Sub-Mariner — or someone claiming to be him — and Captain America stand back-to-back, shields and fists ready, as they're swarmed by the war-hungry hordes of Atlantis. Hovering above them in an eerie green glow is Namorita, clearly imperiled, her fate hanging over the entire confrontation. With cover art by Jordan Raskin and a script from Tom Peyer and Glenn Herdling, "In Deep" makes for a genuinely compelling undersea showdown between two of Marvel's most enduring heroes.
