10 Biggest Iron Man Plot Twists
3. Tony's Secret Brother, Arno Stark
As it turns out, the baby that Recorder 451 saved was not Tony at all. When Tony's father Howard noticed that 451 had secretly, for some reason, engineered the child so that it would not live past 30, he decided to do some genetic engineering of his own. He injected his wife Maria with a serum of his own making, hoping to counteract 451's meddling.
This had the unfortunate effect of throwing the entire genetic process off balance, and the child, Arno, was born extremely sickly. Howard and Maria knew they couldn't allow 451 to discover what they had done, so they decided they had to adopt another child as a decoy. They would continue to secretly raise the bedbound Arno, while pretending that their new child, Tony, was the saviour 451 had designed.
When Tony discovers this, he tracks down Arno, and finds him still bedbound and suffering from a mysterious illness.
