Tony Stark is one of the regular humans. He's a genius, and is the MCU version of Elon Musk in wealth, which combined led to his Iron Man suit that makes him a legitimate superhero. However, in the words of Tony Stark: The Iron Man suit is just a result of Tony Stark's real superpower: ADHD.
Tony Stark has a damaged heart from the plane crash that the Mandarin caused, and because of that, he has an implant made by Dr. Ho Yinsen that keeps it beating. His implant is made out of a stabilized form of Kylight, a metal that is found in the abandoned Stark outpost in the Arctic.
During his time as a comic book mainstay, Iron Man deals with addiction and mental illness, including his addiction to alcohol during the “Demon in a Bottle” arc and his various Iron Man suits.
Throughout his comic book and movie run, Tony Stark (Iron Man's identity) has to wear a special electromagnet and ARC reactor as part of his chest plate. That's because he sustained shrapnel during an injury at war, and the chest plate keeps the small pieces from entering his heart.
The same learning trend happened in Avengers: Endgame when he stayed up all night and learned how to time travel. Part of what makes Tony Stark such a great character is his hyperactivity, but also the good that comes from his hyperfocus.
Summary. Tom Cruise was considered for the role of Iron Man but was not chosen because his asking fee at the time was too high for the studio to risk on an untested superhero property.
Thor's recent physical disability (a severed arm, which is soon "replaced" by a prosthetic arm) is presented as permanent and follows his loss of worthiness, which prevents him from lifting his mighty hammer; thus, he is captured by his enemy, who gleefully severs his arm.
In Iron Man 3, Anthony Stark appears to meet the full criteria for posttraumatic stress disorder. He either does not know enough about PTSD or he is in denial, refusing to recognize his own problem, which is a common occurrence among some of those who suffer similarly in real life.
Direct Cybernetic Interface: The Extremis virus has fused Stark's armor to his body. Initially, the inner layers of the Iron Man armor were stored in the hollows of his bones, but later his entire exo-armor would be contained within carbon nanotubes.
The arc reactor keeps Tony Stark alive. In the different versions of Iron Man, Stark's group has been ambushed in Vietnam, the Persian Gulf, and Afghanistan. Stark sustained serious injuries as a result. He created the personal arc reactor to generate energy for an electromagnet keeping shrapnel away from his heart.
Tony Stark, also known as Iron Man, is often referred to by his superhero identity rather than his academic credentials. It's already been joked about in the comics. Quite a few times in fairness but this one basically sums it up perfectly; Tony Stark kept his technology a secret so it doesn't fall into the wrong hand.
In Iron Man #6, written by Christopher Cantwell with art by Cafu and Frank D'Armata, Tony has to be injected with opioids to save his life. As a result, he becomes addicted to morphine. Iron Man #19 by the same creative team reveals that Tony kept using the drugs "to keep going, stay strong, not los.
In the comics, Thanos and Eros were born on Titan to two Eternal parents, but the children of two Eternals risk being born with Deviant DNA. Eros, then, was born without the Deviant gene, while Thanos was born with the Deviant Syndrome, thus why he's purple and looks nothing like his brother.
Back in the early days of Marvel's Ultimate Comics, the Ultimate version of Iron Man was established as a genius weapons designer who had an inoperable brain tumor (the equivalent of the MCU and mainstream Tony's heart condition).
Jane Foster is revealed as the mysterious masked woman who has been swinging Mjolnir as Thor since the Dude Formerly Known as Thor — now just called the Odinson — was deemed unworthy.
The comics play up her identity as a mystery for several issues, but the movie is forthright about Dr. Jane Foster becoming Thor. In both, she is dying from cancer and finds herself empowered when holding the hammer, even though it leaves her more frail when she is without it.
In the comics, it is explicitly stated that Jane's cancer progresses because the transformation that Mjölnir causes in her thinks it is healing her: namely, it purged the drugs from her chemotherapy treatments because those are technically foreign toxins meant to kill cells.
In this way, Downey's exit has helped keep the MCU fresh to avoid fan fatigue. On the personal side, Downey's comments and discussions in interviews show he's given himself the room to expand to other acting and producing projects and to dive headfirst into his philanthropic efforts.
Why did Robert Downey Jr not want to play Iron Man?
Robert Downey Jr. thought playing "Iron Man" for over a decade was going to affect his acting skills. "You start to wonder if a muscle you have hasn't atrophied," Downey told The New York Times. Downey said he was "a hundred percent" concerned about doing Marvel movies for too long.
Kids -- they squirm in their chairs; they run when you tell them to walk; they stop in the middle of cleaning their room to play with their toys. These are all normal parts of being a kid. But some of this behavior can also be a sign of attention deficit hyperactivity disorder (ADHD).
They keep their things fairly organized and try to avoid making a mess. But many kids and adults with ADHD are the opposite — they're messy most of the time. And it can cause problems at home, school, and work. For example, kids might miss a field trip because the permission slip got lost in their overflowing backpack.
