Bukks are the herd of animals found in the Iridonia region who were initially raised as a food source. A number of Zabrak families are named after Bukks. Zabraks are native to the planet Iridonia, so these names were all derived from Iridonia.
Darth Maul (whose real name is simply Maul) is often considered to be Zabrak, but is actually a Dathomirian.
In the franchise Zabraks can breed with humans, and thus evolved a sub species known as Dathomirian. Zabraks have a strong sense of determination and they are quite independent as well. Zabrak also have facial tattoos which represent their tribe. They have a wide range of skin tones (from peach, to white, yellow, red, brown and black), distinct horn patterns and unusual hair growth (most of the Zabraks don’t have any eyelashes or facial hair). They are near humans but have some distinct physical attributes which separates them from humans. Zabrak are instantly recognisable to fans of Star Wars.
