In Bruce Wayne's future, he frequently questions if he should continue to fight crime as he is growing older and becoming tiresome. His question was answered the night he failed to save Lori Lynch (daughter of Leon Lynch, the new mayor of Gotham) from the clutches of the Makusuta Street Gang that controls vice in Gotham City.
Bruce returned to the cave that night to hang his cape and cowl for the last time (like a dramatic scene from hell's kitchen). One year later, now residing in Metropolis with Alfred, Bruce picks a Daily planet whith a headline that shocks him to the core... "GOTHAM GETS ZOMBIFIED!"
Bruce takes his private jet back to gotham ASAP and on his first encounter with the undead he knows he, and his martial art skills alone, are no match. He must return to his cave to retreive a gift from the Green lantern that he has sworn to never activate unless he had no other option. This gift was a Lantern Ring, with this power Bruce might stand a chance against the Living Dead.
Bruce then returns to metropolis to get the help of friend Clark (aka superman). But when Bruce connot contact Superman, he gets a message from Krypton from Jor-El himself. "Bruce, Cal-El must rest, I understand your troubles and I shall grant you temporary Kryptonian powers, use them wisly Mr Wayne"
Now, exploding with power, bruce is ready to destroy the undead and restore Gotham's peace once and for all.
But there is one thing The Super Bat Lantern did not expect... "What!? the came from WHERE?!"...............
