Sunfire is the perfect enemy for Namor, so that makes this story better than your average Sub-Mariner tale. But that’s probably damning with faint praise, since this book is objectively bad.
Only Namor seems to be able to figure out that water and fire negate each other. Although Namor doesn’t shoot water, so technically it’s fire against flesh.
Sunfire is part of a Japanese plot that will damage the seas. Namor comes in and they fight. Then they reach mutual agreement. Then they team up and beat up the guy who recruited Sunfire in the first place.
Namorita is in these issues, too. She’s largely just a joke–a “dumb little girl” joke. Somehow, when you’re in a book with an obviously over-macho Namor, it doesn’t seem sexist.
Namor also punches a giant frog.
Issue #56 is a fill-in issue.
