The HeiseiGyao has a flat head, which comes to a point in the front. The head is also creased down the middle, rather than flat like the ShodaiGyao. Its wings are more dragon-like than the ShodaiGyao, and its hands are more pronounced. It has a longer neck and tail, and red eyes in its super form. The puppets used to portray the Gyaos are rather advanced in comparison to contemporary kaiju puppets, and are capable of simulating subtle breathing movements in their throats, similar to real-life reptiles.
