This is how Imagine them meeting for the first time

I figure Superman will go to Gotham to save someone, destroying the city in the process. Then Batman will show up and they become bff's. Either that, or Superman is pinned against someone like Brainiac, so the government seeks out Batman for help. Either way, millions die.

Batman will put out an ad online after discovering that the he needs help with crime fighting on the day shift. Clark reads it and applies, when both apply justice they become BFF's with one of them suggesting they wear their undies on the outside just for fun. Then the New 52 will cease to exist.

Like they did in Lex Luthor: Man of Steel. Batman tries to take on Supes and get his ass handed to him.

I think Bruce will meet Superman as Bruce and not Batman. Maybe Bruce will come off at first disliking Superman considering he owns him (Bruce) a satellite.

They shouldn't have an all out fight when they meet but a small brawl like in that clip. Probably Batman doing his business and Superman interfering or the other way around.

Clark will be sent to interview Bruce Wayne about him visiting the city to repair it.

Best way to start it
