During a lull in the War, Captain America, unwilling to
return to the US for a rest with the other Invaders, accepted an invitation to
visit Namor’s home, Atlantis….
Now, Cap and Winter Soldier, turned into water-breathers by Black
Panther’s science, are going undercover in Atlantis to recover the Genus
Compound. But Cap has another mission first: he frees the captive Hydro-Man
from his cage just as an explosion rocks the city. Roxxon troops are attacking
and Namor goes out to face them—but Bucky knows this is a distraction. He and
Cap find a smaller Roxxon squad searching the lab for the Compound. A diver
locates it and begins swimming toward the surface….
Meanwhile, Machan/Roman Peterson with the Serpent Crown is
preparing his device to turn all air-breathers into water-breathers when he
detects intruders. On the surface he confronts Human Torch and Toro and uses
his mind-control abilities to send Toro flying straight up into space, forcing
Torch to pursue him. After a few pages, the lack of oxygen extinguishes Toro’s
flames and Torch is able to catch him and return him to the ground….
Cap reaches the deck of the Roxxon ship and signals for a
drone to drop him his costume and shield. Cap crashes in, seizes the bag with the
compound and then heads for the sea but he runs into Namor who wrongly
concludes that Cap was behind the scheme to steal the Genus Compound. The two
end up fighting the Roxxon mercenaries together and a stray bullet pierces the
Compound’s container, spraying it on the heroes. Namor falls overboard and Cap pursues….
When Roxxon’s Simon Kaito learns of the success in stealing
the Compound, he gives orders to find Cap and Namor….
When Namor awakens, Cap informs him they are stranded on an
island—and the Compound has turned them both into air-breathers….
