Zig is a very hungry hyena, who wants to eat Marina and is one of the titular two main protagonists of Zig and Sharko. He spends most of his time trying to capture and eat Marina, and is frequently seen tricking her into lying down on a giant submarine sandwich roll prepared with veggies and condiments. Despite this, Zig can be a good person depending on the episode. If other threats are to bring harm to Marina, Zig doesn’t hesitate to team up with Sharko to keep her safe. Due to this, he is the on and off hero of the show.
Even though Zig is a hyena, he doesn't particularly look like any of the four real-life hyena species - he has no visible neck, with small, sharp ears, bright-pink eyes closely placed to each other, a short, paintbrush-like tail, dark yellow fur, a mane and a prolonged snout with large teeth, akin to that of a human (at some moments he is shown with more fitting carnivorous teeth). As a result, many viewers mistake him for another animal. Zig is a hyena of short stature, and is scrawny; he has long, thin arms and short legs.
