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.

Cardenas started training in martial arts when he was about 12 years old. He appeared at the 2007 Power Morphicon convention along with other veteran cast members, including Austin St. John, Walter Jones, Johnny Yong Bosch, and Daniel Southworth.[2] He also appeared at Anime Expo 2009 along with fellow veteran Power Rangers actors, Walter Emanuel Jones, Karan Ashley, Blake Foster, Barbara Goodson, and Robert Axelrod, who are best known for their voice actor roles as Rita Repulsa and Lord Zedd, Catherine Sutherland, Selwyn Ward, Patricia Ja Lee, Nakia Burrise, and Daniel Southworth.
