Billy Cranston (Revisited Series)

Billy Cranston is the Blue Mighty Morphin' Ranger. He is the third longest-serving Ranger overall behind Tommy Oliver and Adam Park. Until his departure, he was considered the brains of the Power Rangers team, creating many gadgets with which to solve problems that not even Zordon foresaw, and even invented the first team's wrist-worn communication devices.

In Power Rangers Zeo: Revisited, he leaves Earth to go to Aquitar. He later marries Cestria and becomes King of Aquitar.

In Power Rangers Zeo: Revisited, his role is the same as his prime universe counterpart, only instead of him suffering from accelerated aging, he becomes sick with a flu-like illness and he must be taken to Aquitar to be given strong doses of a water that improves health.
