Trivia

 * This film takes place 8 months after the events of Batman: Arkham Knight, and it's spin off, Suicide Squad: Kill The Justice League.
 * The film features the debut of The Mighty Mutatron and his inclusion as a new DC Comics character.
 * The concept of the the titular character was heavily and loosely inspired by the 2019 superhero horror film, Brightburn. since that film was a take on the Superman origin story detailed in more explicit horror and how Brightburn became a villain, which is the opposite of what Superman is, Mutatron's origin story is a comedic take on the Joker's origin story and that like Brightburn, Mutatron became the opposite of what The Joker is, which the opposite is being a comical superhero.
