I would start Zeo with a Zeoquest television movie. Then, in the first regular episode of Zeo, the Machine Empire attack. When it's time for Trey to give his Gold Ranger power, it is Billy who get it. Then, I would end the series with all the Zeo Rangers losing their powers because their human bodies couldn't hold it any longer. It will also be the reason Trey turn the rangers into giants in the last episode. He wanted them to be able to defeat the final giant before losing their powers. No villains from previous Power Rangers series in my version of Zeo.
