Tony Stark

Tony Stark (Iron Man) is the genius, billionaire, and co-leader of the Avengers. Without biological superpowers, he uses his brilliant intellect to create Iron Man's technology and armor, funding and equipping the team. His definition in three points: The origin: He goes from being an arrogant weapons manufacturer to a hero after witnessing the damage his creations caused. The internal conflict: His fear of cosmic threats leads him to make mistakes in trying to control everything (such as creating Ultron). The legacy: He completes the ultimate redemption arc, going from total selfishness to the final sacrifice with the Infinity Stones to save the universe.
