Tony Stark's Arc Reactor is one of the most iconic pieces of tech in the MCU. Iron Man's artificial heart is — literally — front and center of this beloved comic-book character.
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.
Overview. 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.
After regaining conciousness Tony Stark, using a box of scraps, built a small Arc Reactor, an almost limitless source of energy. He placed it inside his chest to power the electromagnet and no longer had to use the car battery.
The power source for the Iron Man Armor is easily the most expensive part of the suit. Tony Stark created a “arc reactor,” a portable nuclear reactor that smashes hydrogen atoms into helium like the sun, essentially creating an endless power source for the user.
While attempting to shut down this sentient armor, Tony Stark had a heart attack. The armor replaced Tony's heart with an artificial one to save his life, and Tony began steering himself away from such high technology out of fears of this incident happening again.
In the Iron Man 2 novelization, as well as in the junior novelization, the element created by Tony Stark to replace palladium in the Arc Reactor is called vibranium.
Highlights. The Arc Reactor was created in the first Iron Man movie and was initially designed to prevent shrapnel from reaching Tony Stark's heart. Throughout the MCU, Tony Stark used different versions of the Arc Reactor, each improving upon the previous version and increasing the power supply.
The arc reactor, affectionately known as Tony Stark's "heart," serves a dual purpose in the urban comic world. First and foremost, it keeps shrapnel from an earlier injury away from his heart, acting as a life-saving power source to prevent his heart from failing.
After being taken captive by the Ten Rings in Iron Man, Stark equips himself with a miniaturized arc reactor, with the help of Ho Yinsen, which prevents pieces of metal shrapnel from making their way into Stark's heart.
In the feature films of the Marvel Cinematic Universe, Morgan Stark is the name of Tony Stark and Pepper Potts' daughter, who in the 2019 film Avengers: Endgame, is played by Lexi Rabe.
However, the Ironheart mantle is something decidedly different, hence why Ironheart can't simply be referred to as a female Iron Man. Riri was inspired by Stark and is honoring him, but she's not a replacement.
In the Iron Man 2 novelization, the new element created by Tony Stark to replace Palladium in the arc reactor is called Vibranium. This information would later be invalidated by Captain America: The First Avenger, where Vibranium is shown as a rare metal already existing in the 1940s.
Summary. Iron Man's direct replacement, Ironheart, has a cleverly inverted origin story that sets her apart from Tony Stark and establishes her as her own hero. Tony Stark's journey as a hero was defined by making mistakes and atoning for them, while Riri Williams started out as a genuinely heroic person from the start ...
As Tony Stark/Iron Man, the actor looks to be taking his life-saving, power-generating arc reactor out of that hole and placing it back in, and it sure looks real and therefore kinda painful. But that chest is all fake, prosthetics from the makeup artists as seen in the step-by-step illustration below.
Emaciated from lack of food and water, Stark recorded a message using his helmet for Pepper Potts explaining his situation on his time in space. Becoming lightheaded from exhaustion, Stark concluded that he will dream about Potts in his sleep before turning off the recording.
"Tony Stark's story is far from over," Downey said. "Iron Man 4 will explore new dimensions of the character and his legacy through the eyes of Morgan.
Vibranium is metallic element that absorbs sound waves, along with other vibrations such as kinetic energy. So, if a bullet was fired at vibranium, the energy from the bullet would transfer to the vibranium, and the bullet would fall harmlessly to the ground. This makes it nearly indestructible to brute force attack.
When it was suggested early on in Tony Stark's time in the MCU that he get surgery to remove the shrapnel from his chest, he was decidedly against this. He found out that he would pretty much instantly die if such surgery were performed. Because of how the shrapnel had entered his body, it was impossible to remove.
However, he didn't, and for a good reason. Since Vibranium is extremely rare and valuable, it also doesn't come cheap. As revealed in WandaVision, Vision, whose body was made from Vibranium and synthetic flesh, cost around $3 billion of the Wakandan material.
The new Arc reactor uses a Palladium Core inside which is burned during prolong use of the Ironman suit which sends particles of Palladium into Tony's body causing Palladium poisoning.
Famed Wakandan scientist and Wakanda University professor Obinna Nwabueze discovered a new form of vibranium. Testing its subatomic structure, he concluded that the metal had some kind of sentience. The naturally occurring sentient metal came from the echo caves of the Dora Milaje, the king's personal guard.
