Kingsaurus III (キングザウルス三世 Kingusaurusu Sansei) is a dinosaur kaiju and an RP character used by IFIE.
- Horns: Kingsaurus III has three horns on his face strong enough to stab into the thick hides of Ultras such as Jack.
- Barb: Kingsaurus III has barbs on his horns, which activate automatically when touched like a jellyfish.
- Burrowing: Kingsaurus III can burrow at medium speeds underground.
- Blinding Flashes: Kingsaurus III can fire blue waves of energy that can repel or temporarily blind his foe.
- U-235 Beam: Kingsaurus III can fire a light red beam or energy from his mouth.
- Fence Light Wall: Kingsaurus III can create a Force field strong enough to stop the beams of Ultraman Jack. However, it only surrounds/protects the front of Kingsaurus III and the top is left open.
- Damaged Horns: If his horns break he'll be weak.
- Kingsaurus III was originally used by GarudaGoji, then Gallibon the Destroyer and now Wally Rng.
- The reason for the "III" in Kingsaurus III's name is to signify that he is the 3rd Ultra kaiju with king in its name, after Red King and Eleking.
