Return of Ultraman

Twin Tail in Return of Ultraman

In the Jurassic period, Gudon and Twin Tail fought and Twin Tail often used anesthetic venom to run from fights.

When a ancient egg from the Jurassic period was dug up in a construction site, MAT was called to the scene to dispose of the egg but with no success, after one of the members shot it with a ray gun, he declared it an oddly shaped rock. As MAT left to deal with Gudon, the egg was buried again by the construction crew. Shortly after, the egg increased into near Kaiju size and erupted from underground in the middle of Tokyo. Soon enough, the egg hatched and revealed the monster Twin Tail, who began to rampage in the city. Go transformed into Ultraman Jack to confront the monster, and the two had a long and difficult fight. Suddenly Gudon emerged from underground, confronting Jack and his arch rival. Outnumbered and weakened, the two monsters were too much for Jack to handle, who had no choice but to retreat. With Jack out of the way, Twin Tail and Gudon viciously collided. The victor however was never solved as the two monsters separated for the time being.

After doing some research prior to Twin Tail's hatching, MAT soon discovered that Twin Tail was the instinctive rival of Gudon, which explained why Gudon had emerged in the first place. After viewing the damage caused by the monsters, the military threatened to unleash a "Spigun" to slay the two monsters. Knowing many innocent people would die and Tokyo will be destroyed if that happened, MAT decided to try one more attack on Twin Tail and Gudon, armed with nothing but bazookas loaded with paralyzing rockets. Twin Tail appeared first from beneath the Earth and MAT launched their first attack, aiming for the prehistoric beast's eyes and blowing out one of Twin Tail's eye before Gudon erupted from the ground. Ultraman Jack soon returned and subdued Twin Tail, allowing MAT to blow out the monster's other eye. This time when Gudon returned, Jack stepped back to allow Gudon and Twin Tail to fight it out. Twin Tail received fatal wounds by Gudon after being bitten into and being slammed to the ground, killing Twin Tail. Two Giant Monsters Attack Tokyo Battle! Monsters vs. MAT

They attacked it, which greatly injured the monster, giving Mebius the instant he needed to destroy Twin Tail with his Mebium Shoot. Two From the Deep Sea

Twin Tail was revived by Reibatos alongside Vict Lugiel, Gudon, Birdon, King Joe, and Hyper Zetton to fight Ultraman Zero and Ultraman Orb.

He teamed up with Gudon and Hyper Zetton despite being the natural prey of the former. They were quickly defeated by Zero due to the Ultra Warrior's strength and skill. After Zero and Orb defeated Hyper Zetton, Twin Tail caught Zero off guard by constricting his shoulders with his whips as well as biting him in the leg, although Zero managed to break free not too long afterwards.

Later, his old enemy, Ultraman Jack arrived to save Zero. Twin Tail joins forces with Gudon. However Twin Tail failed to hit Jack and after being thrown to the ground and being kicked is defeated by Jack's Ultra Lance. Ultra Fight Orb
