Pterodactyl concept art was submitted by Josh Nizzi early into the development of Godzilla.
Pterodactyl is a small, nimble kaiju. It possesses two long limbs, with stretched membrane that form into insectoid wings. It has a long, spear-like tail and green, scaly skin. Has long, crocodilian-like jaws with a small horn on the top jaw.
The monster's history is unknown. Its relation to the other unmade Godzilla monster, Rokmutul, is also unknown.
- Pterodactyl was likely reworked into the winged M.U.T.O.
- Pterodactyl may be loosely based on Rodan, being a winged pterosaur-like reptile, just as Rokmutul shows evidence of being based on Anguirus.
