Marko is an anime/chibi style character with a teenage appearance. He has short black hair and large blue eyes that aren't directly visible. He wears a black hat with two small horns (these are actually part of his head, though they appear to be part of the hat), and he has a thin white tail that ends in a triangular shape. His outfit consists of black clothing: a short-sleeved shirt and shorts (ending above his knees). He also wears fingerless black gloves that start at the middle of his arms and short black boots. His legs have white bandages wrapped around his ankles and extending to his knees on both legs.

His eyes/pupils are navy blue.
And also when he talks you can see a fang sticking out in his mouth, Yep! He has a fang, It's cute.

HE HAS A VERY LONG TONGUE! I'd say about 25 cm long, the end of it is pointed. But he never usually shows it, perhaps out of embarrassment.
