Batwars: Episode 1, End To Fear.
Batman vs Darth Vader.. a fight debated almost as often as Superman vs Goku. Though Superman vs Goku is rather more impossible to predict. However, now, the debate shall end.. The Dark Knight's Bat Cave, in some strange event even he was unable to see coming, has been transported to a distant world, in an unknown galaxy..
Unable to reach the Justice League, and armed only with his wits and what he has left in the Batcave.. Batman explores the new world, and discovers a war far beyond that of his home world. A battle between two sides, Dark and Light. This Light needs a hero.. no.. not a hero.. it needs a watcher.. a protector who borders on both sides.. it needs a Dark Knight.
