General Calvin Swanwick was a United States Army general overseeing the defense against General Zod, and later became Secretary of Defense.
Man of Steel
General Swanwick was alerted to the Kryptonian invasion by General Zod's global broadcast demanding that humanity give him Kal-El, who soon came to the U.S. military base with the intention of cooperating as necessary for humanity's safety, being questioned by Swanwick.
Swanwick and the military later assisted Superman and others in stopping the invasion by sending the Black Zero back into the Phantom Zone.
Following the battle, Swanwick sent out drones to keep track of Superman's whereabouts, but Superman immediately destroyed them while insisting that the United States and humanity had nothing to fear in him and telling Swanwick that he trusted him to help convince his government employers of this much.
Batman v Superman
Swanwick, now acting as Secretary of Defense, was initially turned against Superman along with much of humanity following the massacre in Nairomi for which he was framed, but was convinced by Lois Lane to examine a suspicious bullet used in the attack, whose manufacture was ultimately traced to Lex Luthor, thus implicating him as responsible.
Upon Luthor's creation of Doomsday, Swanwick led the initial military response to the monster, and unsuccessfully protested the U.S. President's decision to use a nuclear missile against both Doomsday and Superman.
Swanwick was later present at Superman's funeral.
Zack Snyder's Justice League
This section of the history covers the events of the 2021 director's cut Zack Snyder's Justice League. Part of this contradicts the cinematic release of the 2017 movie Justice League. All or part of this section may no longer be valid for the rest of the DC Extended Universe.
As what appeared to be Martha Kent exited Lois Lane's apartment, "she" was revealed to be a shapeshifting alien, which then assumed the form of Calvin Swanwick while muttering that the world needs Lois Lane as much as it needs Superman.
Following the death of Steppenwolf, the alien, in his true form, visited Bruce Wayne to warn him that Darkseid would attack Earth again and that he would help the Justice League fight him when the time came as well as find the Anti-Life Equation before he could, introducing himself as the Martian Manhunter (one of many names he said he was known by).
- Calvin Swanwick was portrayed by Harry Lennix.
- Prior to his departure from the DC Extended Universe, Zack Snyder intended for General Calvin Swanwick to be revealed to be a disguised Martian Manhunter in Justice League. The director's cut of the film restores this reveal in full, but Snyder has confirmed that his cut is non-canon for Warner Bros. Entertainment, Inc.
- If the gap between Man of Steel and Batman v Superman: Dawn of Justice is indeed three years from 2013 to 2016 just like the years where the movies were released, Swanwick's transition from active service Lieutenant General in the United States Army to Secretary of Defense raises questions. The National Security Act of 1947 prohibits active-duty military personnel to serve as United States Secretary of Defense. They are only allowed to do so seven years after retiring. Both the house of Representatives and the Senate would have to have granted General Swanwick a waiver so he'd be able to serve as the Secretary of Defense within this short timespan.
