Hartford was on an expedition when he accidentally discovered the Crown of the Gods, and released Moltor and Flurious from their slumber. The Sentinel Knight told Hartford it was now his job to find the jewels and defend them from Moltor and Flurious.
Creating the Team
He created the Operation Overdrive Power Rangers. He originally planned to be the Red Ranger, but after much relentless urging from his son Mack Hartford; He decided that his son was better suited for the job, despite his own fears of losing Mack.
His preoccupations were explained when Mack was inflicted with a virus and malfunctioned, revealing he was really an android built a little over two years ago. Mack was created because Andrew was unable to meet the right woman due to his work and chose to make himself a son.
When the Sentinel Knight suggested to place the Corona Aurora upon Mack's head, Mack became a flesh and blood son to accompany Andrew in his adventures.
Andrew is wise and kind man. He cares about Mack and always worry about him. He is also little nervous, impulsive and tough but always kind and is always ready to help the rangers. He is always honest, helpful, protective, caring, fatherly and good. Mister Hartford is charismatic, intelligent and brilliant genius, always creates new technology to help the rangers. He has a big friendship with Spencer and rangers.
Andrew shows his skills in robotics again when he repairs and reawakens Alpha 6.
- Andrew is the first mentor of the season not to eventually become a Power Ranger, or never have been a Power Ranger, since Ninja Storm.
- His story as a mentor who accidentally causes the movement of the villains and who must put a team together to stop them is similar to that of Dr. Kyutaro Yumeno of Dynaman.
