The villains get rounded up to create an anti-superman type brigade.
The witch steals the vial with her brother.
The brother gives the witch power so she isn't dependant on her heart which has been taken from her.
The joker shows up to save Harley but the helicopter gets shot down, they both survive just fine.
The Mexican gangbanger grows a pair of balls and attacks the brother, he's able to hold him back while a bomb is detonated , killing both the brother and the Mexican.
Harley tricks the witch and rips out her heart, the bf of the girl who is being used by the witch crushes the heart.
All the criminals get locked up again ad obviously Harley is broken out by the joker.
Batman gets the files of the criminals and makes a suggestion leading to a marvel type movie suggestion.
The movie had to be politically correct so the main boss is a black chick that obviously messes everything up.
Overall 8/10
