Timeline 1: 1380 A.D.

The film opens with the narrator explaining that Aliens have been locking up their criminals for a long time inside human bodies and humans were unaware of this. In this timeline, monk warriors try to kill an Alien and it's host human woman to no avail. Suddenly a portal opens and a jeep arrives. A flying robot takes form from the jeep and another Humanoid robot emerges from the vehicle, named Thunder and Guard respectively. Guard battles the Alien, who has now returned to its human host body and is successfully able to extract the Alien from its Host. The woman, before succumbing to her battle injuries asks Guard to take care of her baby; but Guard informs her they can't interfere in human affairs. Guard and Thunder both then take their human forms and leave this timeline using The Crystal Knife, which is the source of their powers and which also helps them see through time and space to help them catch escaped Aliens.
