Carlos Vallertes, portrayed by Roger Velasco, was chosen by Adam Park (Johnny Yong Bosch) to become the new Green Ranger during Power Rangers: Turbo, taking over control of the Desert Thunder Turbo Zord and later gaining access to the Thunder Loader Rescue Zord. He was originally suggested to share a love interest with Ashley, the new Yellow Ranger.
When the Power Chamber was destroyed by Divatox and the defeated Power Rangers: Turbo received word that the planet Eltar, home to their original mentor Zordon, had fallen to evil forces, Carlos and the other three new Turbo Rangers - T.J., Ashley, and Cassie- left Earth for outer space in a NASADA space shuttle, powerless but ready to fight to save Zordon.
At the beginning of Power Rangers: In Space, Carlos and the other Rangers then met Andros, the Red Space Ranger, on the Astro Megaship, and he was given new powers as the Black Space Ranger, who later commanded the Mega V-2 (Shuttle) Zord.
The Rangers were able to use their powers to stop Divatox and her plans with enough time to graduate.
The Rangers lost their two megazords in the battle (he had tried to self destruct the Rescue Megazord but the giant still lived, the Turbo Megazord had already been damaged beyond repair).
The Rangers and Alpha 6 used the shuttle to go into space, to try and find Zordon (minus Justin who stayed behind to be with his dad and to move to his dad's new job).
PowerRangers: Turbo (often abbreviated as PRT, and often simply called Turbo) was a television show based on the Japanese Super Sentai television series Gekisou Sentai CarRanger featuring the fifth generation of the PowerRangers.
The power of the Zeo Crystal and the Zeo Zords are not strong enough to withstand this new evil, so Zordon and Alpha 5 assist the Rangers in creating the new Turbo Powers, which also give the Rangers new Turbo Zords.
PowerRangers: Lost Galaxy would be the second, with the Magna Defender's morpher and PowerRangers: Dino Thunder would be the third, with the Black Dino Ranger's morpher.
