Zig is a hyena that wants to eat Marina, but is always beaten by Sharko every time. He tries a lot of schemes (which ultimately fail) with the help of his friend Bernie to eat Marina. Zig lives on a small island with a forest and a volcano using everything on the island to aid him eat Marina. It is not known why Zig doesn't eat coconuts which grow on the trees but he has attempted to eat Bernie.
Zig could be called a genius since he has made a evapourising machine (Desert Island Drought), a device which can make it day or night (The Horribly Hungry Hyena) and many more inventions, though Bernie has made most of them.
