Continuity: The Power Chamber drastically changes between series 4 and 5 (for example, the old Rangers costumes and weapons aren't shown), yet no explanation is given.

Continuity: Only a minor mistake - when Japanese footage is used, the Rangers, Elgar, Rygog, and Porthole look slightly different - for example, Elgar & co. look more menacing and detailed (compared to their American counterparts), whereas the Rangers costumes are made of a different material.
