Immortal Legend Batman (Immortal Legend Batman #1)

Humanity broke the barrier between our universe and our universe's shadow. From the void came horrific apparitions that craved nothing but destruction. But from this terror... a legend was born. A warrior who found a way to access the energy that binds our universe and the shadow universe, transforming him into a cosmic dark knight. This immortal legend was named Batman. He fought to keep us safe but then one day abandoned the war. Though he didn't disappear entirely. Now they say he hunts a rogues gallery of monsters... born from the shadows!
