Ripperjack
Creatures native to Necromunda said to resemble a cross between a bat and a piranha. Two radically different "subspecies" have been shown thus far over the years, one from Fantasy Flight Games and one from a more recent Necromunda model. The smaller, more leechlike, Fantasy Flight Games era subspecies is described as "Looking like a cross between a very large bat and a piranha, a Ripper Jack is a voracious hunter which hangs upside down from the roofs of the largest abandoned domes. When they swoop down on their prey, they attack by enveloping their target with their leathery wings, blinding and disorenting them long enough for them to secure their grip. They will always go after the eyes to begin with, then moving onto the face and throat. Unless the Ripper Jack is quickly removed from the person's face, they will shortly be suffocated by the leathery wings or bled to death by the hooker talons." The newer subspecies shown accompanying a Necromunda Beastmaster is much bigger, and has more tendril-like sensory organs.
