Power Rangers Zeo

Power Rangers Zeo is the fourth season of the Power Rangers franchise. It originally aired in 1996, and is based on the Super Sentai series Chouriki Sentai Ohranger. Zeo introduced all-new Ranger costumes for the first time, a pattern that would repeat each subsequent season, in keeping with the Super Sentai source material. Zeo also introduced robotic villains and monsters to the franchise, a pattern that would later continue with Power Rangers RPM.
