Operation Overdrive Power Rangers

Power Rangers Operation Overdrive is the 2007 season of Power Rangers that tells the story of the Overdrive Rangers and their quest to collect the Corona Jewels before the multivarious factions of villains collect them first.

The Operation Overdrive Power Rangers are a fictional team of superheroes in the television show Power Rangers Operation Overdrive, tasked with tracking down five individual jewels that fit onto Corona Aurora. Due to DNA resequencing, they have enhanced strength and intelligence as well as individual superpowers, and wield the Overdrive Trackers that serve as communicators and morphers. They are funded and run by billionaire Andrew Hartford and are based out of his mansion, located in San Angeles.

Mackenzie Hartford, nicknamed Mack, is the Red Overdrive Ranger and "son" of Andrew Hartford. He is the only Ranger not deliberately recruited, being involved in Operation Overdrive by accident and against his father's wishes. Outgoing and enthusiastic, he was sheltered by his father for most of his life and had the desire to prove himself. Though initially believed to be genetically enhanced like the other Rangers, he is revealed late in the series to be an android. His memory is linked to the Operation Overdrive computer, so when it's infected with a virus, Mack ends up stuck repeating himself when the virus gets to him.

Mack is heavily into adventure novels and other escapist fantasies, and is determined to be a Ranger; he takes failure badly, almost quitting when he failed to protect a civilian. He showed bravery and quick tactical thinking in his first battle and has been quickly accepted and trusted as leader by the other Rangers. He has a close relationship with the household butler Spencer.

Mack misinterprets Andrew's concern over his status as a Ranger as a lack of confidence as he overheard Andrew and Spencer talking, but soon patches things up with his father as he realizes that the man simply cares about him and is worried about losing him. His "genetic" power is super strength, though it is likely that his robotic components were simply modified. At the end of the series, Mack has a final battle with Flurious and uses all of his energy to destroy him. The Sentinel Knight uses the Corona Aurora to transform Mack into a human. Mack then spends his human life the way he always wanted – adventuring with his father. He and his teammates would later return in Power Rangers Super Megaforce to battle alongside other veteran Ranger teams and the Megaforce Rangers.
