Return of Ultraman

Twin Tail in Return of Ultraman

In the Jurrasic 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 the Tokyo. Soon enough, the egg hatched and revealed the monster Twin Tail, who began to rampage in the city. Goh 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.


  • Twin Tail's name and his two-tail features is a reference to the twin tail hairstyle. This might explain the reason behind his upside-down position, purposely to resemble a person with such hairstyle
    • This as well becomes a running joke/Japanese meme in the internet, commonly pixiv where fans would draw pictures of characters performing poses to resemble that of said monster by lying their body in an upside-down position.

  • Twin Tail's roar is a re-used Gubira roar.

Twin Tail reappeared in episode 6 and 9 of the series, Ultraman Mebius.

Released into the sea by Bogal from an egg. Drawn by the heat, GUYS eventually found the egg on the seafloor. Once they dove into the sea to find it, Bogal forced the egg to hatch and it released Twin Tail. Mirai quickly turned into Ultraman Mebius, but Twin Tail was too agile in the water, and was winning. But GUYS soon discovered Twin Tail's weakness: The two, glowing blue spots on its body where its sonar organs. They attacked it, which greatly injured the monster, giving Mebius the instant he needed to destroy Twin Tail with his Mebium Shot.

Later on, another Twin Tail appeared and was seen fighting another Gudon, with no one knowing how or why they were alive and fighting. Their fight was halted by Bogal, who beat both monsters into submission before eating them alive.
