Fake Ultras appear several times in the Ultra series.
Alien Babalou appeared in the series as Imitation Ultras. To get his revenge on the Ultra Brothers, Alien Babalou disguised himself as Astra after capturing him, froze him in a block of ice, and abandoned him in the middle of space. Disguised as the Fake Astra, Babalou then stole the Ultra Key, a device that both maintained the Land of Light‘s orbit and was capable of destroying an entire planet in a single blast. Before he could escape, Fake Astra was confronted by Ultraman over taking the key. Despite being overpowered by Ultraman, Fake Astra escaped the planet, leaving the Ultra Brothers to believe Astra had betrayed them and worse, without the Ultra Key to keep their planet in orbit, the Land of Light was sent into a collusion course with Earth. Fake Astra made his way towards Earth, where he planned to use Leo’s trust in his brother to trick Gen into protecting him from the Ultra Brothers until it was too late to avert the collision. Once Gen and Dan found Fake Astra, the doppelganger pleads with Gen to save him from the other Ultras who were chasing him. Gen fell for his ruse. Dan however knew he was a fake and used his Ultra Will Power on him so the Ultra Key could be recovered by his brothers. Oblivious, Gen fought with the crippled Dan to protect his "brother" until Zoffy, Ultraman, Jack, and Ace arrived and overwhelmed Fake Astra.
After battling with Dan, Gen transformed to come to his "brother’s" aid, fending off the Ultra Brothers. Leo tried to talk some sense into Fake Astra, but with Earth slowly falling apart and with the Land of Light's collision nigh, Ultra Brothers had no choice by to fight Leo and Fake Astra to try to get the Ultra Key back. During the battle, Ultraman, Jack, and Ace fired weakened versions of their signature rays to end the battle quickly, but Fake Astra cowardly used Leo as a shield to protect himself. Leo took the brunt of the attacks and was badly wounded. With Leo out of action, Fake Astra prepared to use the Ultra Key’s devastating power against the Ultra Brothers and destroy them. Before he use the weapon, Ultraman King arrived to thwart the diabolical alien. He fired a beam of energy from his color timer, shattering the disguise and revealing Babalou’s true face.
Ultraman Hikari saga
Alien Babalou reappeared in the 3rd and final episode of the Ultraman Hikari Saga. As Ultraman Hikari was planning on returning to Earth, he received a distress signal from his old home planet of Aabu. Arriving on the planet, he was confronted by a being that looking identical to that of Ultraman Mebius. Noting that Mebius was still on earth, Hikari and the impostor battled on Aabu until the Impostor transformed into Hikari's old form, Tsurugi, taunting Hikari by proclaiming that as Tsurugi he was once more powerful by thriving on his vengeance against Bogal, but has since grown soft since being accustomed by humanity. The Fake Tsurugi then transformed into Alien Babalou and both alien and ultra battled.
