Subtitle: Ancient Monstrous Bird (古代怪鳥 Kodai Kaichō?)
- Height: 52 m
- Weight: 14,000 t
- Flight speed: Mach 2.5
- Origin: Ancient ruins in Mexico
One night, an ancient creature at the Southern border of Mexico awoke. His name was Reguila, based on an ancient Mayan god, and bursted through the ground around a ruined Mayan temple. DASH was aware of Reguila's presence and used Mother DASH to chase after him. DASH Birds were sent after Reguila, but Kaito's arrogance from an earlier argument got the better of him as he risked his life twice to turn into Ultraman Max to no avail. Reguila's eye darts shot his fighter down and the assault on Reguila had to stop. Reguila appeared the next day in the city of Saipan and would soon arrive in Japan. After a couple missiles from DASH, Reguila fell in an area full of windmills and quickly got up. His hurricane force winds annihilated everything in front of him. Koba and Sean were shot down by Reguila's chest beam and once they crashed the bird-like kaiju walked towards them while they were knocked out. Before Reguila could use his pincer claws, Kaito showed up and shot the creature with two homing rockets from a DASH van. Reguila began to follow Kaito and once his eye darts weren't enough he used hurricane winds that sent the van flying. Kaito managed to turn into Max and clashed with Reguila. Try as he did, Reguila was of little match for Max's power and once Max escaped his chest ropes he used the Maxium Sword to cut Reguila in two. As Reguila tried to fly off, he became electrified and soon exploded.
- Reguila's roars are generic elk bugles, with some snarling from the Jurassic Park Velociraptor thrown in.
