Iron Man Noir (2010 series) #2

Tony Stark, James Rhodes, and Pepper Potts embark on their search for Atlantis. They depart from Spain in the Lady Dorma, a trawler whose captain is the notorious pirate Namor. Tony gives Pepper a history of Atlantis and the story of orichalcum, the “metal of the gods,” which acted as a super-conductor, amplifying power; a statue of Poseidon held a trident with a head of orichalcum. He also confides in Pepper about his father, broken by his experiences in a German POW camp during the Great War, and becoming a great inventor….

Approaching the site of Atlantis, the crew breaks out Stark’s miniature submarine; Tony, Rhodey, Pepper, and Namor voyage under the ocean and discover a mountain of wrecked ships, twisted into a vortex. An opening underneath leads to a cavern full of air where they discover the statue of Poseidon. Tony tests the orichalcum with a single volt of electricity and instantly the cavern is brightly lighted. They take the trident head and return to the ship…

…where they find the Nazis, led by Baron Strucker and Baron Zemo, have taken over. Gialetta reveals that her notes were a plant to get Tony to find the orichalcum for them. Tony sets off a gas trap but the Nazis grab Pepper and take off in their speedboat back to their sub and a torpedo is fired, blowing up the Lady Dorma….
