Iron Man (Robert Downey Jr) was the hero that kicked off the Marvel Cinematic Universe, and as such, he was the first one to get a sequel, but Iron Man 2 couldn't match the quality and success of the first movie. Following his confrontation with Obadiah Stane and his encounter with the Ten Rings in his debut movie in the MCU, Tony Stark’s journey as a superhero continued in Iron Man 2, where he, once more, faced two villains as one used the other to fulfill their own plans.
