The Rangers discover the fate of Zordon, and learn all about the threat of the Machine Empire. As King Mondo launches an attack by testing the Earth's defenses, sending a small group of Cogs to Angel Grove, the Rangers prepare to harness the use of the Zeo Crystal's powerful energies to gain new powers to face the new threat. But first, Billy makes a decision which will affect both his life, and Tanya's. Meanwhile, as Lord Zedd and Rita flee to Master Vile's in Serpentera (with Zedd vowing to return), the amnesiac Goldar & Rito beg Bulk & Skull into letting them be their personal servants!
