|This article is about a/an episode in Power Rangers in Space, the last installment in the Zordon Era.|
The Power Rangers recover their Mega Vehicles, which had been stolen by the Psycho Rangers. But when the Mega Voyager is once again formed, it turns out that Psycho Yellow has taken control of the Megazord from within, turning it against the Rangers. But Psycho Red, having become fed up with Astronema interferring with his plans to destroy the Red Ranger, causes the Psychos' plans to fall apart and the Rangers regain control of the Mega Voyager. Taking advantage of Psycho Red's impatience, all six Power Rangers work together in a final battle against the giant monster forms of the final three Psycho Rangers.
