Nozdon is a very tall and muscular man, being significantly larger than the majority of his crew. He is bald and has a dark mark that reaches from his nose to the top of his head. It is unknown if this is hair, a tattoo, or some other marking. He appears to have a similar marking on his left forearm. He has bags under his eyes, a round nose, large lips, and a square chin. His neck is very thick, making his head look slightly lower on his body than normal. He wears a light-colored sleeveless shirt.

In his initial flashback appearance in the anime, the mark on his head is colored the same as his brown skin tone and his shirt is dark gray.[2][4] In a subsequent flashback in the anime, the mark is colored brownish-orange, his skin is a lighter tone, and his shirt is light green.
