Good Episode. I liked the great fights and the zord battle was awesome and touching at the same time.
The basic plot was that the Rangers were trying to stop Grunchor, a gigantic monster that Captain Mutiny had tricked the colony into letting loose during the last episode. While trying to stop it the Rangers also run into Deviot and learn how to stop Grunchor, and run into Barbarax and a lot of Swabbies. This leads to some awesome fights that show off the true skill of the Japanese stunt team.
Grunchor eventually grows into "zord-slamming" proportions and it takes all of the Rangers' skill to stop him in a surprisingly touching scene when they all gather around one of the zord control panels, together in the zords for the very first time. They combine their energies and manage to destry Grunchor.
Very Good Episode overall.
Ciao!
