Red Hood tries to escape to a parallel Earth with the Phase Oscillator, but is thwarted by the Injustice Syndicate.
To infiltrate the Injustice Syndicate of a parallel Earth, Batman takes the place of his villainous counterpart Owlman (whom Batman defeated and imprisoned in the Batcave's cell). He infiltrates the Injustice Syndicate and gains the unlikely alliance of Red Hood and heroic counterparts of the villains Batman has faced.
