thats what i think too just don't know how they will kill doomsday thought.

Okay so how does everyone die?

And yes it is world war hulk and the doomsday that killed superman

okay then maybe Lex if they are even and Braniac is good  but even then Braniac just calls superman or something . lol

can he use the knowledge of his previous forms ?

who wins this over kill or does doom have a chance?

Okay since Braniac 5 can travel through time he has infinite time .

ya possibly it just sounds really cool.

 I do not think so since Brainiac is from the future so he would be way ahead of Lex any way and giving him no morals when he is good is just overkill .
