It follows the origin of Superman, including his infancy as Kal-El of Krypton, son of Jor-El, and his youthful years in the rural town of Smallville. As the “everyman” reporter, Clark Kent, he learns that he is a superpowered alien from the planet Krypton and assumes the role of mankind's protector as Superman and adopts a mild-mannered disposition in Metropolis and develops a romance with Lois Lane, while he faces unintended consequences after he intervenes in an international conflict orchestrated by the villainous billionaire Lex Luthor. Superman must win back public support with the help of his reporter and superhero colleagues, making the choice to face General Zod and stop him from destroying humanity.
It is the Second Chapter of the First Arc of the First Generation and the First Entry of the Superman Saga in the DC Fictional Universe (DCFU). The Last Son of Krypton symbolizes idealism, contrasting the symbol of cynicism of Batman/Joker. The film is compared to Richard Donner (Superman, 1978), Bryan Singer (Superman Returns, 2006), Zack Snyder (Man of Steel, 2013), and James Gunn (Superman, 2025).
