Ok, after listening to ideas and whatnot, I've come up with what I want to see in the next films.
1. Begins
2. The title for this is Batman Two(I think it's fits quite well) Two-Face is the main bad guy(with acid contributed by the mob) he goes around with his grudge against Batman and the justice system. He plans to blow up Wayne Tower unless he gets 5 million dollars(he would have made it 2 but he has bills to pay: that is from DKR) and Batman stops him after a sweet fight at the end.
3. This is called Batman: Venom
In this film, Richard Grayson's parents are killed by Tony Zucco. He becomes Robin(without the green shorts) Joker finally reveals himself and tells Batman about his plan. It is simple, with the help of Dr. Crane, he creates Joker Venom. But after a quarell, Joker tests his venom on Crane, leaving him death with a smile.(whoever thought that idea up is genius!)He plans on using the venom to leave Gotham smiling forever. After leading them through tons of stuff, the finale begins. After a struggle on Joker's blimp, he shoots Robin and wounds him. Batman punches him. Joker falls out of the blimp, but he just smiles as he lands in the lake. Batman takes Dick to the Batcave and Alfred fixes him up. But Dick decides to go around the world, searching for an answer to his life question.
And that is what I think...
