Batman becomes Deified
Based on This Post about Batman being accidentally turned into a God by the people of Gotham’s belief
So, if this was the case, I feel like some of his fellow godly teammates would notice and/or comment on it. But since they assume he already knows, they never really directly state that Batman is a God.
Diana would just say something like “It is a good idea for Batman to take care of the hostages on this mission, all things considered”, and Batman thinks it’s just a dig at his so called “adoption addiction” sinc emost of the hostages are kids.
Or Captain Marvel says “It’s an honor to meet you Mr Batman sir! Never really get to meet other people like me!” and Batman thinks it’s because he’s the only Hero from Faucett City, and he’s excited to meet another Hero
Or even Constantine making jokes like, “Would you let me off the hook if I sold you my soul” and Batman thinks it’s a joke but Constantine is being entirely serious about this, since Batman is a God and he could definitely take a persons soul.
And also, the day he joins the League the amount of people who think he’s a God skyrockets. There’s no way a normal guy would be on the same team with the likes of Wonder Woman and Superman without being a God himself. That point is proven even further when Captain Marvel, another God, joins the team.
Then one day, Clockwork drops in and tells Batman that he wants him to take care of Danny, because he needs somebody who can take care of both of his sides. Since Batman used to be a Human, he would be able to relate to Danny in that regard.
And Batman is just like “What the hell do you mean ‘Used to be Human’, what happened to me!?”
And after he finds out that he is a Minor God of Protection and Children, his full powers come to light.
He rushes to the League, and tells them that he has somehow attained Godhood. And Diana and Shazam are confused, saying “What, did you not know? You’ve been a Minor God since I met you”
And Constantine is laughing his ass off that Batman legitimately did not know he was a God.
And the chaos that would ensue from that would be hilarious.
