The Brzak appears to be an oversized bull shark, though it was of human origin. It appears to be blind as it was not impaired after being struck in the eyes with a harpoon, and presumably it uses electroception to navigate, as other predatory sharks do. Its tongue is vastly deformed, boasting a bright orange extension covered in bony protrusions, and takes up a large portion of the creature's head. This tongue appears to be capable of extending to ensnare its victims. The creature's fins appear to end in claws, which enable it to navigate rough terrain and pursue its prey through not entirely aquatic environments.
