Originally intended for 65 episodes, Fox Kids bumped up the order to 70 and did not want to further the series. But Saban asked them for another season, so that they could wrap up some of the storylines left lingering. Eventually Fox Kids agreed to six more episodes.

This explains why the last six episodes looked different than the previous 70.
