Dex Stewart

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!" The hero of the story. Dex originates from the fallen planet of Edenoi, homeworld of Alpha 5. 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. Dex has superhuman strength, super-speed, and telekinetic abilities. While trying to blend in, he appears unusual to everyone else. He is portrayed by T.J. Roberts.

The main title character of Masked Rider was featured on a 3-part Power Rangers episode before his own series started. The Rangers themselves were never mentioned in the Masked Rider television series, however, as Saban reformatted the series to sever links with Power Rangers, because the popularity of that series was declining at the time. The Rangers did, however, make a guest appearance in Masked Rider's short-lived comic book adaptation.
