Chouriki Sentai Ohranger was built around the idea of an ancient civilization possessing powerful technology.

That gave the team a distinctive combination of archaeology and science fiction. The Rangers could be associated with a very old legacy while using futuristic weapons and machines.

The series also carried the significance of being associated with Super Sentai’s twentieth anniversary period.

The ancient-technology concept allowed the production to design robots and equipment that looked powerful and monumental.

Ohranger is therefore another example of the franchise’s love of combining the distant past with an imagined technological future.
