"Last Son" is a five-issue comic book story arc featuring Superman in the monthly Action Comics. It was written by Geoff Johns and Richard Donner, the director of the well-known 1978 film Superman: The Movie and a portion of Superman II, with pencils by Adam Kubert. This story introduces the original character, Christopher Kent and adapts the classic Superman film villains, General Zod, Ursa and Non into the regular DC Universe continuity.

General Zod is a supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Superman. The character, who first appeared in Adventure Comics #283, was created by Robert Bernstein and initially designed by George Papp. As a Kryptonian, he exhibits the same powers and abilities as Superman and is consequently viewed as one of his greatest enemies alongside Lex Luthor, Darkseid and Brainiac. He is also well known for his famous catchphrase, "Kneel before Zod!".
