With just few weeks left for the release of "Avengers: Age Of Ultron", theories on the film continue to gain a steady pace, and the latest among it is on "Iron Man 2" that hints at the future of Tony Stark in Marvel's Cinematic Universe.

The theory explains the superhero's arc reactor, which was created with the help of his father's research book. The fictional scientific explanation elaborates on the birth of a critical weapon and if it is proved true, then the life-saving device will have a major role to play in upcoming Marvel movies.  

The theory published by MoviePilot explains that the mounted element on the superhero's chest could be an Infinity Stone that could make him the key to defeat Thanos in "Infinity War".

In "Iron Man 2", the industrialist is seen creating a powerful mystery element by referring to his father's notes on how to make The Tesseract. The film also foreshadowed the sequence of "Captain America: The First Avenger", in which young Howard Stark gets his hands on the critical weapon after Cap's death, according to Cinema Blend.

Further strengthening the theory, the website reminds Marvel fans a sequence between Loki and Tony, where in the formal fails to use his magic power on the latter. As per the fictional scientific explanation, both the characters might have related powers that could have interconnected with each other. 

However, the life-saving device is said to be Vibranium in the novelisation of "Iron Man 2" and it even stated that the weapon is created with same elements used for making the shield of Captain America. 

Marvel fans will have to wait for the release of "Avengers: Age Of Ultron" on 1 May to know more about the future of their favourite superhero.
