Infinite Frontier #4

Description

"President Superman finds himself in the wrong world, and it isn’t looking good. Bones and Chase attempt to stop super-powered heroes and villains from crossing Multiversal lines. If they can shut down the President of Steel, they think that it will serve as a signal to all to not mess with Earth-0! This is only a distraction, however, as Injustice Incarnate begins to show them the worst the Multiverse has to offer, and only Flashpoint Batman is there to lend the heroes backup."
