One of our favorite superheroes is Iron Man or Tony Stark, portrayed by actor Robert Downey Jr. Well, the actor turns 55 today, and he has amazed us with his performance as Iron Man. The superhero film is a follower worldwide, and Iron Man has fans all over. So on the birthday of the actor who portrays the role of Iron Man, we bring you 5 things unknown about our favorite Avenger Superhero.

Robert Downey Jr. has been playing Iron Man for almost ten years now. That’s longer than most today. But at age 55, he’s also the oldest superhero to still fight on the silver screen.

When wearing the Iron Man suit, Tony Stark can lift up to 100 tons. This is a remarkable feat, as it is the same amount that the Hulk can lift when he is calm. Tony later created the Hulkbuster armor, capable of lifting 175 tons, to confront the Hulk in specific situations. Additionally, he has designed a black Iron Man suit called the Stealth Armor, which is not detectable by radar.

In the comics, Tony Stark requested to be trained by Captain America to remain useful if he didn’t have his Iron Man suit available. He turned out to be quite the fighting force afterward.

Tony Stark is constantly upgrading and optimizing his Iron Man suits. In the comic book universe, he’s made roughly 53 different suits. He’s also made a “rescue suit” for Pepper Potts.
