"Ultimate Iron Man" #5 shows that shortly after Howard's arrest based on planted evidence (by Obadiah) at the gruesome murder of his enemy Zebediah Stane, Tony gets his first taste of champagne at a party held by his father. Tony was warned against alcohol by his father because it would affect his brain more than a normal human due to his decentralized brain tissue and increase his chances of alcoholism. He later says that while he was intoxicated, it was the first time in his life he was not in chronic pain. After Howard's incarceration, Tony takes control of his father's company. Its at this point where two prototype variations of the suit are shown. One is roughly tall, designed for more practical testings, while the second is a large suit at least tall, for designing any additions to the traditional suit before including them to the more restricted design. The suit doesn't fly, but hovers or bounces and is not completely stable. Stark is forced to use the prototype to foil a terrorist plot to destroy his building. Though Tony is successful, the terrorists manage to detonate the bomb prematurely and completely destroy the suit. Tony is also injured, but due to his physiology, bounces back quickly.
