 Originally intended for 65 episodes, FoxKids 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 FoxKids agreed to six more episodes.  Unfortunately, at the time Marvel was filing for bankruptcy and  could not afford to produce more episodes, so Saban funded them  directly. This explains why the last six episodes looked different  than the previous 70.
