The Batman (Apr 2012)

I really liked the idea of having a broken batman from the death of robin but it was done poorly. This movie would adapt batman: a lonely place of dying and introduce an expanded bat family. After the death of Jason Todd, Bruce has become reckless and emotional. Tim drake works out that bruce is batman and goes to Wayne manor to help but only finds Alfred. Both being worried they find Nightwing and they both go after Bruce who's gone after Two-Face. They help Bruce get over the death of Jason and they deal with Two-Face
The Flash (Sept 2012)

Barry is the main flash. Barry has been the flash for a while now and is loved by the people of Central City. He's a skilled forensics scientist and has a reporter girlfriend, Iris. This movie introduces Wally and he becomes kid flash and they both defeat Gorilla Grodd.
Aquaman (Dec 2012)

Keep it mostly the same as the first movie but change the main villain from Ocean Master to Black Manta.

Villain: Lex, Amazo, Deathstroke, Weather Man, Chemo
Bruce, Clark and Diana have become close they meet at a cafe. but they are alerted by screams of people being attacked by Deathstroke, Weatherman and Chemo. They try to stop the fight but are outmatched, Chemo weakening Batman and Weatherman and Deathstroke handling Superman and Wonder Woman. They stumble back to the Batcave wondering what to do and what caused those villains to team up. Files are pulled up to explain the villains to each other (and the audience). Realising that they're out powered Bruce pulls up some files on other metahumans (Flash, Aquaman, Cyborg).
They each go after one and recruit them to help. Bruce goes after The Flash relating as they both work as detectives. Wonder Woman Goes after Aquaman both as a leader of a mythological species. Superman meets Cyborg relating to him as a alien living amongst humanity. They get to know each other and they deal with the trio once more but now it's not just them its also Amazo. They get beaten and Amazo gets most of their powers.
As they get back Bruce suggests that they share weaknesses to take down the robot. Clark goes ahead and says his weakness to Kryptonite. Barry says that he's weak to ice and it slows him down. Aquaman and Wonder Woman both decline sharing their weaknesses to the group as their species share weaknesses and people could take down their species. After another failed attempt with the robot Wonder Woman and Aquaman reveal their weaknesses. Cyborg speaks says that he's weak to technology. They go to take on the robot terrorising the city and defeat it as a united team.
Post Credits Scene: Lex meets with Deathstroke as he says "sorry we failed" and lex replies saying "no need I got all I need" showing Amazo in an incubation tube and a folder with the title Public enemies (Setup for MOS 2)
