There is an ancient prophecy shared amongst the kingdoms of Earth - 2,000 years after their fall, the Earth Empire Bugnarak will once again rise up to kill all humans. However, five kings and their guardian deity, King-Ohger, will stand up to face them. This is the story of kings who will defend the Earth, as well as a Coming of Age Story for one young man who will achieve kingship henceforth. (Source: powerrangers.wikia.com)
