Prince Dex Stewart is the main protagonist of the series Saban's Masked Rider. He is able to transform in to the Masked Rider when Dex yells out the phrase, "Ectophase Activate!"
He is a prince of the planet Edenoi, homeworld of Alpha 5, and the current Masked Rider: the guardians of Edenoi. As with all his race, he possesses a gem in his forehead that channels various powers, including broadcasting his memories into thin air.
Dex's grandfather, King Lexian, gave Dex the Masked Rider powers when the planet was attacked by Count Dregon - Dex's uncle, and a tyrant who coveted the powers for himself. While the planet fell, Dex continued to lead the resistance to his uncle's tyranny.
Mighty Morphin Power Rangers
He encountered the Mighty Morphin Power Rangers during a battle, where he initially thought they were working for Dregon. After a brief fight, the heroes teamed up to take down the tyrant's Plague Patrol and Cogwarts. The Rangers and Dex departed as friends, but it was now clear that Dregon was turning his sights towards Earth and Dex would need to travel there to stop him.
The hero of the story. Dex originates from the fallen planet of Edenoi. On Edenoi, he is its prince and his grandfather is the king. In Edenoi's royal family, the powers of the Masked Rider are passed down from generation to generation. As the current Masked Rider, Dex is sent to Earth to stop his evil uncle, Count Dregon, from enslaving the Earthlings. He is adopted by the Stewarts and tries to interact with American culture. Dex has many capabilities that Earthlings don't have. He can materialize a crystal on his forehead to transmit his thoughts to others, use it to scan and x-ray, and sense nearby danger, he can also emit a high pitched noise which can knock out nearby lifeforms. Dex has superhuman strength, super-speed, and telekinetic abilities. While trying to blend in, he appears unusual to everyone else.
