Billy And Cap Are Different People But Are Connected - Tumblr Posts
Billy and Captain Marvel are such sweethearts. If he saw you fall down he would purposely fall down as well to make you feel less embarrassed, he'd pick up litter at the park, offer to take a photo of a couple, handwrite a letter to a fan, buy lemonade from a stand (if he has extra money), and leave positive notes in library books.
What other small but kind thing do you think he'd do?
Evil Billy AU
Imagine if Captain Marvel couldn't turn evil but Billy could, kind of like a Jekyll and Hyde situation. I don't think Captain Marvel could ever actually physically kill anyone, even if he wanted to. The power of Shazam is given to people pure of heart and then changes them to be their ideal selves. Black Adam became a warrior fighting for freedom, the wizard Shazam became an immortal protector of magic, and Billy became an powerful heroic version of his father.
Black Adam became a killer after losing his son but the reason why he's so easily made that change was because he was a warrior in the first place! Captain Marvel on the other hand is formed from the idea of a parental figure and a protector. So even if he did hit someone with all his powers I think subconsciously something would stop him from going too far. However the same does not apply to Billy himself, so while everyone's worried about Captain Marvel turning evil but they should really be worried about Billy.
