|This article is about a/an tribe in Kyoryu Sentai Zyuranger.|
The Yamato Tribe is ruled by a king and queen; but in the period of 170 million years ago, they were forced to adopt a child due to not having their own. Without guidance of the king, the queen adopted Geki, the younger of the two sons of the Black Knight (a great warrior of the Yamato Tribe), to make as their heir against his will. The Black Knight was angered and waged war against the Yamato royalty, leading to his ultimate death by way of the king. While Geki remained tied to the Yamato royalty, the Black Knight's elder son Burai never forgot what he witnessed even after he was taken to live among the fairies and even as his younger brother entered cryogenic slumber after the initial defeat of Witch Bandora.
During the final rebellion of Bandora against the dinosaur tribes, the Yamato King, Queen and their ten year old daughter were killed by the witch until the Guardian Beasts intervened to put a stop to her aspirations. As the prince of the Yamato Tribe and it's main survivor, Geki was made Tyrannoranger and placed into cryogenic slumber to awaken if Bandora were to return.
