Past Ground Squadron Rangers

The previous generation of Ground Squadron Rangers. They defeated an invading force known as the Pack.

Team History
Just after the chosen teenagers became Rangers, the Pack's invasion began. Thanks to defectors on Tethys they were able to get through planetary security, and even destroyed the Rangers' first Zords, but thanks to Thulos's quick thinking they were able to halt the first wave.

Afterwards, the Pack continued sending down monsters, and Li led defensive maneuvers while Thulos used his connections to a spy network to track down the traitors and eliminate them. The Pack began turning them into mindless monsters to prevent them being captured, which eventually led the last, a man named Narn, to betray them and help the Rangers.
