Nook (ヌーク Nook) and Terra (テラ Terra) were cyborgs who were originally survivors of the ancient civilization that perished thirty million years ago. They mainly lived in space via their spaceship and later returned to Earth when Gijera struck.


Ultraman Tiga

In the depths of the forest, deep underground, Gijera commanded its flowers to emit their yellow pollen, causing Rena and the other members to behave strangely. Daigo went back to base with them, a sample of the plant, and a strange girl he’d found wandering the woods. Something in her speech reminded Daigo of the prophecy that had been given from the ancient race. As they worked to try to work it out, more of Gijera’s plants began releasing their pollen all over the city. Deep within the Earth, Gijera continued to infect everyone coming in contact with its spores. In fact, only Daigo and the young girl appeared immune. The girl suddenly collapsed in front of Daigo and another man suddenly appeared. He introduced himself as Nook and the little girl as his daughter, Terra. The man reveals that the appearance of Gijera was the beginning of the end for the ancient race from which Daigo descended, as it could very well be for mankind. Its only because of his bond to Tiga that Daigo is immune to Gijera’s pollen and is the only chance mankind has of survival as Gijera matures and grows into a towering monster. The two leave Daigo to do what he will with Gijera.

After Daigo as Tiga destroyed the Gijera, the two cyborgs appeared in front of him as spirits where he apologized at them since Gijera's pollens were the supplements needed in order to ensure their survival. However, they said that it doesn't matter as long as the Earth is safe.
