Blue Senturion is a robotic intergalactic police officer.
He was voiced by David Walsh. In the Japanese dub from the series, he was voiced by Yoshimitsu Shimoyama.
Blue Senturion came from the future to give Dimitria the Millenium Message, a message that Divatox, the Machine Empire, Lord Zedd, Rita Repulsa, and many other villains would come together and conquer the universe.
Unfortunately, Divatox kidnapped, and tricked him into giving her the message by impersonating Dimitria's voice, and messed with his system to attack the Rangers. The Rangers were able to turn him back to normal and he became an excellent ally to them.
Divatox even used a wishing coin from one of her monsters, Wicked Wisher, to turn the Blue Senturion evil. But luckily, Justin found the final wishing coin and used it to wish Blue Senturion to be good again.
Blue Senturion went to Eltar to fight against the Untied Alliance of Evil. However, the 2 were majorly outnumbered and were captured. The two were saved by Zordon's Energy Wave.
- Since he has a ranger key and is in a poster of Blue Rangers as of Ninja Steel, he can be considered a ranger.
- He made a cameo in the Power Rangers S.P.D. episode "Stakeout" fighting against Cyclopter by the B-Squad Rangers.
