Kurt Langstrom (Earth-5641)

"I spent my life as a scientist trying to create a world without weakness, without outcasts. I sought to create a stronger human being, but there's no such thing. Humans are weak, pathetic, feeble-minded creatures. Why be human at all when we can be so much more faster, stronger and smarter? This is my gift to you."

Doctor Kurt Langstrom was a scientist working for the Weyland-Yutani Corporation, who specialized on genetic engineering. Using the help of his student, Jessica Drew, Langstom acquired a serum which allowed him to cure his deafness, but also turned him into a hulking creature called Man-Bat.
