We don't actually get to see Jason Mamoa as Aquaman's Arthur Curry, but we feel like he would approve of his character's mention in the Shazam! post-credits scene. Freddy (aka baby Seth Cohen) continues trying to figure out the scope of Billy's powers. They both learn that Shazam isn't able to communicate with fish and thus, won't be able to "command an army of billions in the sea." Shazam laughs and notes that he doesn't think it's that cool of a power anyway!
