Batman: Gotham by Gaslight – A League for Justice #4

The League for Justice has found itself against a foe like none other: General Zod! Will this newly formed team succeed in their struggle for control over the Kryptonite Core power source and its near-infinite power, or will the dreaded general use its power to make the very Earth kneel before him? Meanwhile, Cyborg and Flash — the two newest additions to the League, who are still getting acclimated to life outside Luthor's laboratory — discover a dark secret that Batman is hiding in his cave.
