Synopsis for "Scale Model"
In the Curios shop Billy Yuan admires the dragon idol, and Fin Fang Foom telepathically convinces him to steal it. Meanwhile on his yacht, Stark publicly unveils Happy as the new Maria Stark Foundation liaison for local affairs. As Happy answers reporters' questions, Iron Man takes Stark away on a harness-chair. Stark folds the remote-controlled armor into its module form and hides it in his trunk. Pepper phones and towards a call from Count Andreas Zorba, who requests Stark Solutions' services locating a treasure, but Stark declines. Fin Fang Foom uses his statue to take control of Billy's body. In Los Angeles, Charles Gray is abducted by two men; they force him into a car, where he is greeted by an unseen passenger, and moments later the car is filled with a flash of light. Stark is having dinner with Dr. Ramona Napier in the Space Needle, when he hears of a disturbance in Seattle on the news. He excuses himself with a "call" from Iron Man and soon finds a mutated Billy breaking into ATMs. During their fight Billy mutates some rats into lizards, but Iron Man overpowers him. When the police arrives, the lizards merge with Billy, transforming him fully into Fin Fang Foom.
