Tony Stark is a multi-billionaire and the head of Stark Enterprises, the world leader in weapon industry. His injured heart forced him to create a mighty armor which he use to protect himself and fight evil and injustice as the armoured avenger - Iron Man. His arch enemies are the Mandarin, a powerful sorcerer, eager to get his hands on Stark's inventions and Iron Man's armor, and Justin Hammer, Stark's number one rival and Mandarin's ally in order to destroy Stark.
In the first season, Iron Man fought the Mandarin along with his team - the Force Works, which members were War Machine (James Rhodes), Spider-Woman (Julia Carpenter), Hawkeye (Clint Barton), Scarlet Witch (Wanda Maximoff) and Century.
The second season was much darker, and it focused more on Stark's personal issues and issues of other main characters.
The series was aired as part of Marvel Action Hour along with another Marvel comic based series - The Fantastic Four
