An alien that calls itself the “ruler of the dark universe”. Alien Babarue is one of the most cruel and merciless alien in the galaxy and plans to take over the universe. Its weapons are the blade on its right arm, and the chain flail fired from the rocket anchor on its left arm.

Alien Babarue intruded the Land of Light and used its chain flail to break into the Ultra Tower. To steal the Ultra Key, a device that controls the trajectory of M78, it transformed into Imit-Astra. Alien Babarue set the Land of Light on a collision course to crash with Earth.
Pursued by Zoffy, Ultraman, Jack, and Ace, Alien Babarue used its disguise to deceive Leo and planned to make the Ultras fight with each other.
