- There was an ancient human civilization on Earth, it was protected by the Ancient Ultras. Among the threats were the Kilaliens, who desired control over mankind but were stopped by the Ultras. It is unknown where they came from, but it is known they came from another world.
- A civil war between the Ultras broke out, most likely due to the machinations of the Dark Giants. How it ends is unknown, but numerous giants are left as stone.
- During this conflict Tiga fell in love with the original Yuzare, turning to the side of good, ultimately resulting in his former companions being sealed away. Tiga then went on to be a protector.
- Humanity fell victim to the spores of the Gijera plant. Refusing to over turn human free will, the remaining Ultras left, leaving behind stone replicas of themselves. Tiga's statue was left in the Golden Pyramid with two others.
- With their protectors gone, mankind was left defenseless against the onslaught of monsters, particularly the Zoiger and the rising of their master Gatanothor.
