Nelgel dresses in a black shirt with lime-green pants, pink boots, and a green coat with the skull of a monster serving as a cuirass that tapers into a lavender cape. Nelgel's skin is a light shade of purple and his hair is white; two large, curving horns emerge from the center of his skull and extend back to his shoulders. A large scythe is his main weapon in his humanoid form.
Once transformed, Nelgel resembles a stygian simian with a bulky upper body, bat wings, bird legs, and a thin tail. His skin is green and covered in purple markings.
