Billy Batson (DCEU)

Billy Batson is the superhero Shazam! After saving his foster brother Freddy as he was being assaulted by bullies outside of school, Billy ran from said bullies until escaping inside the subway train. The train came to a stop in a weird location, and as Billy walked out to it, he was greeted by an elderly wizard, who had chosen him to be his champion after his selfless act. Following the wizard's instructions, Billy touched his scepter and said his name, "Shazam", which made him be struck by a lightning and become a muscular adult in a caped suit. Billy awakened back in the subway, and after it stopped, he ran back to his foster home to ask for Freddy's help, finding him the only one who could aid given Freddy's fandom of superheroes.
