Shouldn't even have gotten mind controlled
If you look in the lore, Superman thought that Brainiac was friendly and even though Batman and Wonder Woman thought it was a trap, they just all went in unprepared anyways
And, making Deadshot black and having the other Deadshot be a fake was just bad
And also, why would Batman just come out and show that he's not dead after Superman comes in, that doesn't sound like Batman at all
