Synopsis for "The Serpent Crown Affair Part 1: From the Depths!"
Fearing that he is constantly puttingAlicia in danger,Ben decides that it's best that they break-up so that Alicia is no longer in any danger from any of theFantastic Four's villains. This upsets Alicia who tearfully, and angrily accepts it, and Ben regrets the suggestion right after she slams her door on his face but decides to stick with his decision.
Returning to theBaxter Building, where he helpsReed Richards out in the lab, they are interrupted by the arrival ofWalter Newell (aka Stingray) and his colleagueHenry Croft. The two men have come seeking Reed Richard's aid, as Henry and a group of people living onHydrobase had been turned into amphibians by the villainDr. Hydro and all their attempts to restore everyone on Hydrobase to normal have to date failed. After hearing about how Dr. Hydro changed all the people of Hydrobase into amphibians Reed agrees to help.
Meanwhile,Thundra has gone back to the gym where she was tricked into helping theGrapplers in invadingProject Pegasus on the behalf ofRoxxon Oil. Inside she confronts her former managerHerkimer Oglethorpe, however before she can get information out of him she is confronted by his bodyguard and sometime wrestler,Hyperion. While out on the New York/New Jersey highway,Aquarian wanders the streets and saves a deer from being struck by a car.
Back at the Baxter Building, Ben is roused from a dull exercise session by Reed Richards, who informs Ben that he found similarities between Dr. Hydro's formula and theInhumans'Terrigen Mists. Having contacted the Inhumans, they had agreed to give Reed a sample, and so Reed sends Ben, Walter, and Henry to meetTriton inCalifornia to pick up the Terrigen Mist sample.
Arriving on the California coast, Walter notices a suspicious looking Roxxon Oil rig, and comments on how it's in a location where there are no oil deposits, Ben simply dismisses it as they land thePogo Plane in the ocean and wait for Triton's arrival. With some time to kill, Ben and Walter decide to investigate the strange oil rig, Walter changing into his Stingray costume.
When they approach the Roxxon Oil Rig they are asked to leave by the workers, when suddenly an underwater explosion damages and destabilizes the rig's ability to stay afloat. As Ben keeps the rig upright, Stingray jumps into the water and tries to find out the cause of the explosion. To the Thing's surprise, he is attacked by the rig workers, and Stingray finds himself attacked by a bunch of underwater divers.
As the two heroes manage to fight off their attackers, they are suddenly brought to the attention of an approaching submarine. When the sub rises from the water, from its exit hatch comes a new group of costumed super-villains: TheSerpent Squad.

Notes
Continuity Notes[]
- Ben decides to break up with Alicia due to his concerns over her safety. This culminated in a number of issues. Namely when she was turned into a spider-woman byHydra inMarvel Two-In-One #31–32, had her art show crashed by theTerrible Trio inMarvel Two-In-One #60, and when she was kidnapped byHer inMarvel Two-In-One #61–63. The two eventually get back together inMarvel Two-In-One #70.
- Dr. Croft mentions the time Doctor Hydro mutated him and the crew of an aircraft turning them into the Hydromen, this happened inSub-Mariner (Vol. 2) #61.
- Stingray mentions his previous encounter with Triton of the Inhumans inSub-Mariner (Vol. 2) #31.
- The theory that there might be a connection between the Inhumans and the Hydromen turns out to be true. As revealed inMarvel Two-In-One #71 the gas that Dr. Hydro used was derived from theTerrigen Mist that is used to empower the Inhumans.
- Thundra recalls her brief wrestling career and how she got swindled into working for Roxxon to infiltrate Project PEGASUS, this was chronicled inMarvel Two-In-One #53–58.
Continuity Errors[]
- TheFantastic Four previously visitedHydrobase and met the Hydro-Men inSuper-Villain Team-Up #7, though Ben and Reed are depicted learning of them in this story as if for the first time.
