The Iron Man trilogy follows Tony Stark's transformation from a reckless billionaire to a selfless hero. In Iron Man (2008), Stark is captured by terrorists and builds a suit of armor to escape, later using it to fight his mentor-turned-villain, Obadiah Stane. In Iron Man 2 (2010), Stark grapples with public pressure, health issues, and a new enemy, Ivan Vanko, while forming alliances with Black Widow and War Machine. In Iron Man 3 (2013), Stark faces PTSD from his experiences in *The Avengers* and confronts the mysterious Mandarin and the dangerous Extremis technology. Throughout the trilogy, Stark learns to embrace his humanity, proving that he's more than just the armor.
