Compared to its RaishuGaru counterpart, the ShodaiGaru evokes a more organic design. It has a beige underbelly and wings. Two puppets were made, with one representing Garu Garu after it lost its disguise. In Rebirth of Mothra II, the first puppet was modified to look more robotic, equipped with piston-supported wings and and weapons mounted on its flanks. This puppet is also known as the KaiteiGaru (海底ガル?) in KaiteiGaruRebirth of Mothra II.
