From Rising Sun Tokusatsu:
Long ago, in the time of the dinosaurs, the earth was invaded by forces
from outer space. The only people capable of the stopping them was a
team known as the Kyouki Ryu no Sha, the People of the Strong Dragons,
or, Kyoryuger for short. Now, in the modern world, they return using the
powers of the Beast Batteries to fight off this revived threat.
Sounds a little like Zyuranger with the whole warriors reviving thing. Sounds like it will be fun though. Can't wait to see the premiere episode!
