Lightning monsters are creatures from Zambian myth.
The description of these creatures is fairly simple: the head, body, and forelegs of a goat, and the hind legs and tail of a crocodile.
Lightning monsters descend from the heavens on a thread of lightning, not unlike a spider, before rebounding. However, occasionally the thread will break, and they must be killed by a warrior with protective charms. If they are not slain, they will wreak havoc on the earth.
