Ant-Man is a superhero character from the Marvel Comics universe. The original Ant-Man was scientist Hank Pym, who invented a suit that could shrink him down to the size of an ant while still retaining his full strength. Later, the mantle of Ant-Man was passed on to Scott Lang, a former thief who became a hero. The character is known for his ability to change size, as well as his appearances in the Marvel Cinematic Universe (MCU) films, including Ant-Man and Ant-Man and the Wasp.
