Cestro, is the Blue Aquitar Ranger of the Aquitar Rangers. He is an Aquitian that requires waters of Aquitar in order to live.
He is also referred to as Blue Alien Ranger on Earth, as well as Mighty Morphin Alien Blue Ranger a variation on his alternate in-show label, though it is more in reference to the show itself than a proper label.

History
Like his Mighty Morphin counterpart, Billy Cranston, Cestro is a technological genius. When Billy successfully managed to restore his own age by means of the Power Coins before they were destroyed, he and Cestro frequently worked together to find a similar cure for the other Rangers - as well as finding a means to keep the Aquitians hydrated with pure water. In this way, Cestro was the Alien Ranger who received most attention in storylines (alongside Delphine, the team leader).
Zeo
Cestro had a guest appearance in Power Rangers: Zeo, in which he came to Earth again, seeking Billy's help to fight off a menace on Aquitar called the hydro-contaminators. Billy's trip to Aquitar saw the beginning of the story arc in which he was permanently written out of the show. Indeed, the Aquitian that Billy falls in love with on Aquitar, Cestria, is believed by some to be Cestro's sister or similar relative (though others dispute this because of the different races of the actors playing the two characters).
In Space
During the invasion of the universe by Dark Specter's United Alliance of Evil, Cestro and the other Aquitian Rangers battled Divatox's army on Gratha, where they were defeated. They were later saved by Zordon's Energy Wave. TV STORY-Countdown to Destruction
Super Megaforce

Cestro is seen with the Aquitar Rangers.
Cestro and the other Aquitian Rangers returned as part of the army of Legendary Rangers that helped the Mega Rangers defeat the Armada once and for all, fighting in a huge battle against hundreds of X Borgs and dozens of Bruisers. He then returns to Aquitar. TV STORY-Legendary Battle

Shattered Grid
Teaming up

All Rangers reunited against lord Drakkon
When events set into motion by Lord Drakkon caused the timeline to split into a pocket universe, each anchored on a powerset, the Alien Rangers were split off into their own pocket universe. Blue Aquitar Ranger eventually received Zordon's call through the Morphin Grid and was among numerous Rangers who rallied to his pocket dimension led by the Quantum Ranger for the last stand against Lord Drakkon, reunited in the Command Center.
