Kala, Queen Of The Netherworld!
Tony Stark, along with a few bystanders (but without his trusted attache case!), is kidnapped from his factory and taken to the Netherworld, an underground civilization descended from Atlantis. Kala, their queen, plans to invade and conquer the world above, but lacks the means to get her forces above ground -- hence why she captured Stark: either the scientist develops a way for her to reach the surface, or she kills all the captives.
Stark pretends to agree, and asks to be in a private lab and not to be disturbed. He makes a model of his Iron Man armour, and claims that Stark had drilled through to the surface to get him. He then manages to fight off all of Kala's defences, and then takes her to the surface, where he shows her that a hostile takeover would be pointless, as she ages dramatically in the surface air. Kala agrees to let Stark and his friends go, and takes another person who lives underground, named Baxu, to be her husband.
