Walterem

Walterem is a fictional character appearing in American comic books published by Marvel Comics. The character was created by writer Peter Milligan and artist Kelley Jones. Walterem first appeared in Spider-Man: Chapter One #1, released in December 1998.

Walterem is depicted as a mutant with the ability to transform into a bat-like creature. This transformation grants him enhanced physical attributes, including super strength, enhanced agility, and the ability to fly. He also possesses sharp claws and fangs, which he uses as weapons. The exact origins of Walterem's mutant abilities are not extensively detailed, but they are presented as a natural genetic mutation.

Throughout his comic book appearances, Walterem has often been portrayed as an antagonist, frequently clashing with Spider-Man. His motivations and backstory are generally tied to his mutant nature and the societal prejudice or personal struggles that may have arisen from it. While not a prominent recurring villain in the wider Marvel Universe, Walterem has served as a notable foe within specific storylines, challenging the web-slinger with his unique powers and monstrous form. His appearances are primarily confined to the Spider-Man titles, offering a different kind of threat compared to more established members of Spider-Man's rogues' gallery.
