The most common terrestrial vampire, this small rodent-based mutant commonly seeks out partnership with other vampires, particularly its own kind, to establish colonies beneath towns and cities. Its highly advanced sense of hearing can focus in on sounds many miles away, and its eyes can peer through solid matter at close range. Lacking a mouth opening, it feeds exclusively on blood through its hollow but unbreakable fangs, which can vibrate at high speed to chisel through even the toughest lead piping or concrete floor.
