As Hayata attempted to return to Earth in his VTOL, Zarab confronted him and confirmed his intentions to conquer and enslave the planet because it was his "job". As Hayata attempted to radio Muramatsu, Zarab revealed his knowledge of Hayata being the secret human host of Ultraman, before knocking him unconscious and crashing his VTOL. Zarab returned to Earth, where he imprisoned Hayata and took the form of Imitation Ultraman. In this disguise, he briefly wreaked havoc across the city of Tokyo.

Alien Zarab then appeared at a Space Center meeting and suggested that Ultraman was an alien bent on world domination, and that the SSSP was sympathetic to him. He further insisted that the SSSP should be ordered to attack Ultraman if he were to return. Returning to the imprisoned Hayata, Zarab attempted to confiscate the Beta Capsule, but was unable to find it, as Hayata had forgotten to bring it during his investigation. Immediately after Zarab left the room, the honorary SSSP member Isamu Hoshino discovered Hayata, and returned to him the Beta Capsule. At the same time, Alien Zarab I assumed his disguise as Imitation Ultraman and resumed his rampage near the Space Center.
