In keeping with my rainbow theme, the first goddess of Zulu mythology would be Nokhubulwane (Mbaba Mwana Waresa). Besides being the goddess of rainbows, Nokhubulwane is also the creator of beer and the goddess who presides over agriculture and rain.
Unkulunkulu, the greatest one also the Ancient One, is the creator of humans. He was born in a swamp of reeds and then came to earth. He is the First Man, and is in everything that he created. He created everything that is the inanimate to the living. He also taught the Zulu all of their skills from fire to hunting and growing food.
Unkulunku is sometimes a combined personage withUmvelinqangi (uKqili), the sky god, also god of earthquakes and thunders. Umvelingangi has been there since the beginning of time. According to Zulu myth, humans are mortal because of a very slow chameleon named Unwaba. The chameleon’s color changes from green to brown because it is mourning the sloth that lost humans their immortality.
Another prominent deity is the goddess of the rivers, Mamlambo. She is variously described as a large snake-like aquatic creature or as a half-fish, half-horse monster. She has a hypnotic gaze and glows in the dark. Mamlambo drowns her victims. She loves thunderstorms.
More fun Zulu cryptozoology includes:
Tikoloshe is described both as a dwarf-like water spirit or as a dwarf with only half a body. It fights humans and usually kills them. It is often used to scare children into behaving. If a human somehow manages to defeat it, the Tikoloshe will teach them its powers.
If one sleeps to close to the ground, a Tokeloshe will strangle them in the night. This is given as the reason most Zulus sleep on beds raised on 3 or 4 bricks at each post.
