JUSTICE LEAGUE OF AMERICA STORY IDEA
So this story starts at Batman 3 or The Dark Knight Rises (if they did this I would be so happy)
At the end of the credits of the Dark Knight Rises, Batman is chasing 3 robbers in a car with his bat-pod or batmobile, then the car crashes to a pole then Batman comes out of the batmobile chasing the robbers while running, then a figure flies over Batman without knowing what it is because it was too fast, then Batman stops wondering who or what that figure is. Then we here’s 2 gun shot, Batman runs faster then sees the 3 robbers tied up with a metal. Then he sees the figure standing right beside the robbers. Then Batman said “Who are you?”
The figure was walking then there’s a light and we see Superman (Brandon Routh) and he says “I’m a friend.” Then Batman says “I read about you. What do you want?” Then Superman says “We need your help.” Batman says “Who’s we?” Then out from the shadows we see Green Lantern, Wonder Woman, Aquaman, The Flash (Barry Allen), and Martian Manhunter. Then Superman looks at the said characters then back at Batman and smiles. Then they fade.
(I'm really sorry if you think it's short, it's just part of it,and it's really hard to make a story, just wait)

Sorry if Megan fox is Wonder Woman on the First Poster I can't find a JLA poster with Cobie Smulders, but I have a DC Trinity poster with Smulders.
