Niko has a well-built and muscular physique. He has a medium-length blonde hair, partially obscuring his red eyes. The sharp, demonic features manifest through his sharp teeth, and some glyphs around his neck. He is always dressed in a white shirt, jeans, and a black coat, using some big belts to carry his weapons. His attire is completed with a black choker, a matching necktie, and stylish sunglasses. A grown man, who actually has mommy issues and has a bad relation with his mother.
