We see the space, there is a big ship with the form of a metallic skull, inside of it there is Brainiac. He gave to Krypton the technology for cloning childrens, and then he killed them by overpowering the inside of the planet. He was created for the purpose of the knowledge, he goes to world and world to collect knowledge of the cities in their best age for stealing that knowledge and the destroying the planet so they can't fall into a dark age. He spot a kryptonian energy in the planet earth, he already got the kryptonian's prisoners, but he miss one with yellow solar energy. He goes to earth.
After this we're in Metropolis one month after the events of JL part 1 (that I will rewrite) there is this man named John Henry Irons that's sick of Superman's White Saviourism, he want to be a black Superman because he doesn't believe that a white man can be a good person. He wrote a murales with the script "Superman's white saviourism called me a NIGGER". He create his own suit in th STAR labs.
Brainiac comes, he doesn't do anything. An albino man in a wheelchair spots him (the Ultra Humanite) and try to make contact Brainiac with a kryptonian technology he stole. Brainiac send a Brainbot to him and try to abduct him, and then Superman came and stop the robot.......
And this was the trailer!
