John Byrne had been back at Marvel for a while before he took on the challenge of doing a new Sub-Mariner series. And it works. Namor was believed dead at the end of the Atlantis Attacks storyline that ran though Marvel’s 1989 annuals, and here just shows up bursting out of the ocean to attack the natives on a nearby island. Researchers Carrie Alexander and her pop, David, see this, recognize him, and help him out. Turns out David has a theory to modulate Namor’s extreme moods — and it works. So Namor enlists them as he digs up sunken treasure to fund a corporate front to fight ocean pollution and other causes. The art is pleasingly detailed, open, and inviting. The story has enough action and plot to keep things interesting enough to make me want to come back for the next issue.
