Justice League: Warworld DVD

Who is the mysterious gunslinger with a golden lasso; the barbaric warrior with a dark knight's helmet; and the mild-mannered, bespectacled G-man? More importantly, how are they key to rescuing Wonder Woman, Batman and Superman--who disappeared from Earth--from the walking hell that is the omnipotent battle planet Warworld? Their disparate fights for survival in seemingly unrelated time periods could lead directly to unravelling the fate of the entire Justice League itself--as well as a looming crisis in the DC Universe.
