Power Rangers: Mystic Force (May 30/06, October 20/06, & November 25/06)
Mystic Force marks the fourteenth (!) show to carry the Power Rangers name, and though each series introduces different characters, they're all essentially the same: Five ragtag teenagers must join forces when they're recruited to become Power Rangers. The show follows their efforts to balance their tumultuous everyday lives with their need to occasionally save the universe.
This time around, the five teens - Nick (Firass Dirani), Xander (Richard Brancatisano), Charlie (Nic Sampson), Madison (Melanie Vallejo), and Vida (Angie Diaz) - are recruited by a mysterious sorceress named Udonna (Peta Rutter) and assigned the task of protecting the earth from a whole host of evil demons bent on world domination.
Power Rangers: Mystic Force - Broken Spell collects the first three episodes of the series: Broken Spell, Part 1, Broken Spell, Part 2, and Code Busters. In both episodes of Broken Spell, we meet the five rangers and discover exactly why their services are needed. The episode also makes it clear that Nick - the red ranger - isn't as readily willing as his compatriots to take up the Power Ranger cause, though (as expected) he's completely won over by the end of the second episode. Code Busters follows the Rangers as they learn more about their special powers, and wind up working together to vanquish a seemingly unstoppable enemy.
Power Rangers: Mystic Force - Dark Wish comes equipped with a three-part episode entitled (not surprisingly) Dark Wish. The episodes pit the Ranger against their old foe Imperius, who successfully strips the five heroes of their ability to use magic. This sets into motion a chain of events eventually culminating with an appearance before the Tribunal of Magic, where the Rangers must plead for the return of their supernatural powers.
Power Rangers: Mystic Force - Legendary Catastros contains the following four episodes: Legendary Catastros (revolving around the Red Ranger's efforts to extricate himself from an alternate dimension), the two-part episode The Gatekeeper, and the Red Ranger-centric Whispering Voices.
Power Rangers: Mystic Force - Fire Heart comes equipped with the following four episodes: Fire Heart, Petrified Xander, Scaredy Cat, and Ranger Dawn.
It's clear that the show isn't meant for anybody over a certain age (say, eight), but it's just as obvious that viewers within the target demographic will probably get a real kick out of these three episodes.
