Arno Stark is a character that appears in the Marvel Comics series entitled Iron Man. He is the foster brother of Tony Stark, and the true biological child of Howard and Maria Stark.


The Secret Origin of Tony Stark

Maria Stark had suffered numerous complications during her pregnancy, and was told the prognosis of her child surviving birth was not good. Desperate to save his unborn son, Howard Stark travelled the world in the hopes of finding a mind greater than his own that would be willing to help him. He found one in the form of Rigellian Recorder 451, an extraterrestrial android that had been observing Earth for decades. 451 agreed to help, but he had a heavy price: He had envisioned humans one day controlling a massive Empire that would rule the known galaxy, but humanity needed a champion that would ensure that it would survive to see this future, and as far as 451 was concerned, any "initiative" that Colonel Fury was putting together was simply not going to cut it. The "son of Stark" would have to be a scion of a new breed of humanity - superior even to these mutants that were starting to reveal themselves - whose very existence would advance humanity's technological growth by at least 50 years. The Starks reluctantly accepted 451's terms and gave birth to a healthy child... but never fully trusted 451's motivations. Sure enough, it was soon discovered that the child had a killswitch built into his genetic cocktail to ensure that he would fulfill his intended purpose when 451 returned. Howard managed to engineer a biococktail that neutralized the killswitch, but it resulted in the son having severe medical complications. In order to maintain the charade in the event of 451's return, they adopted a boy named Tony and raised him as their own, while the biological child, Arno, was kept hidden within a medical facility within the Stark Foundation. Howard and Maria were killed in a car accident before they could inform either brother of the other's existence. However, Howard did make a recording that revealed the truth, with a trail of breadcrumbs to ensure that Tony would find it once he was ready to start looking.

A City of The Future

By the time the Stark Brothers finally met, neither 451 or the Mandarin were active threats any more, so they decided to pool their resources together on an ambitious project to turn Mandarin City into Troy, an ambitious city of the future.

Original Sin

Arno's research into the Extremis virus enabled him to save the life of Bruce Banner when he was shot by an insane assistant who feared the threat he posed as the Hulk. Not long after his recovery, Banner discovered that Tony had tampered with the Gamma Bomb that resulted in his original transformation, removing the shielding that Banner had intended for it to have. Believing that Tony, through either negligence or sabotage, was ultimately responsible for his condition, Banner confronted Arno, blackmailing him into injecting him with a new strain of Extremis, which enabled him to retain his intelligence when he transformed into the Hulk, then went after Iron Man in revenge. Ultimately, Iron Man and the Hulk call a truce when it's discovered that Tony's "tampering" ultimately saved Banner's life... had the Gamma Bomb detonated with the original level of shielding, Banner would have been killed. Arno would later use the research he used to "upgrade" the Hulk to rewrite his own DNA, seemingly curing himself of all of his physical disabilities.

"Please, "Mr. Stark" was my father. Call me Arno."
―Arno introducing himself
"Everything in my entire life has been leading to this. It's my destiny. This is the year I save all life on Earth... and nothing will stand in my way."
―Iron Man 2.0...or is it 3.0?
"Until now, I've failed to bring A.I. and humanity together into the unified force I'll need. Trying to reprogram all robotkind didn't work... but now I see it's because they're not the real problem. Machines make sense. It's humanity that's complicated... irrational... unruly. Once I've installed my new invention on the Stark Space Station, all that will change. Every man, woman and child will obey me... without question. This is my penultimate task. Once it is all completed, all that will remain... is the sole reason that I, Arno Stark, exist-- To save you all!"
―Arno goes mad with power
