Power Rangers Operation Overdrive

Power Rangers Operation Overdrive is the fifteenth season of Power Rangers. It aired on ABC Kids starting on March 3, 2007 after starting on Jetix a week earlier. It is based on the 2006 Super Sentai series, GoGo Sentai Boukenger. Power Rangers Operation Overdrive commemorated the 15th anniversary of Power Rangers, while Boukenger celebrated the 30th anniversary of Super Sentai.

Production History
The early working title for the series was Power Rangers Drive Force, but was later changed to "Relic Hunters" and then "Operation Overdrive"

In early pre-production, on July 26, 2006, the series' logo was posted on a fan message board called "Fuñaroboard."

The logo is very similar to that of its Sentai source series Boukenger in the basic design and format.

On November 14, 2006, Disney had set up its official website for Power Rangers Operation Overdrive.

With the fifteenth anniversary of the series upon them, the producers elected to reward the fans and the show's legacy with a two-part anniversary special uniting Rangers from each of the previous Disney-era seasons, coupled with a popular Ranger from the show's most popular seasons during the 1990s. It had been long established that Johnny Yong Bosch had gained a noticeable reputation as Adam Park amongst the fanbase, and thus was asked to be the returning veteran Ranger for the special.

This season also became the first since Power Rangers Zeo (excluding the preemption of the S.P.D episode Wormhole) to end with a one-episode finale. The season also contained one of the more thought-provoking episodes of the series run, Things Not Said, which began a darker direction for the Red Ranger Mack.

Jackie Marchand says Overdrive was pitched as "Indiana Jones... a new exotic location every episode" and Disney responded favorably - only to then give them a small budget and ask for the use of more stock footage. This made the show more of a challenge to work on.

Synopsis
Many years ago, two brothers named Flurious and Moltor try to steal a legendary crown known as the Corona Aurora and are imprisoned throughout the galaxy. Sentinel Knight scatters the crown and its jewels on the planet Earth in hopes of preventing it from falling into the wrong hands. In the present day, world renowned explorer Andrew Hartford uncovers the crown, which frees Flurious and Moltor from their imprisonment. Andrew recruits four elite teenagers to become Power Rangers and stop the Corona Aurora from falling into the wrong hands. Although Hartford is originally opposed to it, his son Mack becomes the fifth team member - the Red Ranger. The Power Rangers search ancient civilizations and all over the world to uncover the first jewel which was once used by Neptune - King of Atlantis. In the process, they encounter the illustrious Miratrix, who is determined to find the jewels and free her master Kamdor.

While searching for the Toru Diamond, the Rangers encounter an alien named Tyzonn. Tyzonn came to Earth from the planet Mercuria to stop the evil Fearcats who are intent on releasing their army which had been previously imprisoned in a mirror world. After the apparent demise of his fiancée Vella, Tyzonn is reluctant, but is eventually convinced to join Operation Overdrive as the Mercury Ranger. Together, the Rangers encounter Thor and Loki, two of the Norse gods. Their involvement leads to the discovery of the Blue Sapphire, which is stolen by Kamdor and Miratrix.

When Thrax, son of Lord Zedd and Rita Repulsa escapes imprisonment from the Sentinel Knight, he recruits Flurious, Moltor, Kamdor, Miratrix, and the Fearcats to form an evil alliance and destroy the Rangers' connection to the Universal Morphing Grid. The Rangers must go on a quest to seek out the legendary sword Excelsior which is capable of restoring their powers and the Sentinel Knight. With the help of five former Power Rangers – Adam Park-the Black Power Ranger, Xander Bly-the Green Mystic Ranger, Bridge Carson-the S.P.D. Red Ranger, Kira Ford-the Yellow Dino Ranger and Tori Hanson-the Blue Wind Ranger, the Power Rangers unite and take down Thrax, which breaks apart the evil alliance.

After the Rangers encounter a virus, Mack makes a startling discovery about himself. Realizing that he is an android, Mack begins to question his very existence, but he still pulls through for his friends by merging with the Sentinel Knight to become the Red Sentinel Ranger. Meanwhile, when another Fearcat named Crazar shows up, Tyzonn discovers that Vella is still alive. Also the Rangers uncover the Star of Isis, the fourth jewel of the Corona Aurora.

The Octavian Chalice holds the power to uncover the final jewel to the crown. In an ultimate struggle for it, the Fearcats are destroyed for good and so is Kamdor, but not before imprisoning Miratrix inside a gem for eternity. Flurious destroys Moltor and steals the crown and gets his hands on the jewels as well. Now with the power of the Corona Aurora at his disposal, Flurious freezes all of San Angelas. In a desperate attempt to save the world, Mack sacrifices himself to destroy Flurious once and for all. The Sentinel Knight appears and uses the Corona Aurora to bring Mack back to life. As Mack awakens, he realizes that thanks to the crown, he is now human. Thanks to Norg, Tyzonn is reunited with Vella and the Power Rangers move on with their lives now that they have saved the world from evil. this is the lowest rated season having a 1.2% on all platforms of review.
