Kirk Langstrom (Earth-8920)

"I have only ever loved two people in my life... and now they're both gone."

- - Batman to Green Lantern

Doctor Kirk Robert Langstrom is a former Gothamite scientist who specialized in the study of bats in an attempt to cure a tumor that was slowly consuming him. A college friend of Will Magnus and Tina Johnson, Langstrom was on the verge on the success, when the experiment ultimately failed, transforming him into a vampire. Faking his own death, Kirk started to feed on the blood of criminals to keep himself alive, becoming known as the urban legend Batman, and a founding member of the Ultimates.
