Gogmazios is a massive Elder Dragon with a body structure similar in nature to that of Gore Magala and Shagaru Magala. It has a large, heavy head with red eyes and rows of sharp teeth. When it uses its Oil laser attack, a glowing pattern, reminiscent of a scowl, is present beneath its chin, giving it the semblance of a second face. Its wingarms feature membranes that almost completely retract when not in use, and its body is covered in thick, powerful scales, carapaces, and spines of an indigo colouration. Perhaps the most notable features of Gogmazios's body are the ever-present covering of a sticky, tar-like substance which it uses to incapacitate prey, and the presence of an ancient dragonator lodged in its back.
