Stephen Antonio Cardenas (born May 29, 1974) is a former Mexican-American actor and martial artist, perhaps most noted for playing Rocky DeSantos in the Mighty Morphin Power Rangers TV series.

Cardenas was born at Langley Air Force Base, in Hampton, Virginia, U.S. and is of half Mexican descent.[1] His character, Rocky, replaced Jason Lee Scott (played by Austin St. John) as the Red Ranger in the Mighty Morphin Power Rangers TV series, and he later became the Blue Ranger for Power Rangers Zeo. Cardenas left the Power Rangers series at the beginning of the Turbo season, after he was really injured while filming the last episode of Power Rangers Zeo.
