Sub-Mariner #63

Namor surges forward on this 1973 Marvel cover with fists outstretched and fury on his face, while smaller figures battle in the churning waters around him — the corner blurbs promising "Dr. Hydro Returns!," "Atlantis Besieged!," and "Namor at Bay!" all at once. John Romita and Joe Sinnott make the ocean feel like it's crackling with kinetic energy, framing the Prince of Atlantis as a force of nature bearing down on his enemies. With Bill Everett and Steve Gerber sharing writing duties and the story titled "…And the Seas Shall Explode!," this issue looks to deliver exactly the high-stakes underwater chaos that cover promises.
