Stephen Antonio "Steve" Cardenas is a American martial artist and former actor, 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, but was raised in San Antonio, Texas. He is of half Mexican descent. He started training in martial arts when he was about 12 years old and reached black belt in tae kwon do at age 16. Steve Cardenas has been in martial arts for 28 years. He earned 5th degree black belt in tae kwon do and a black belt in Brazilian jiu-jitsu. His character, Rocky, replaced Jason Lee Scott as the Red Ranger in the Mighty Morphin Power Rangers TV series, and he later became the Blue Ranger for Power Rangers Zeo. He had no previous acting experience and had to learn on the job. Cardenas left the Power Rangers series after Zeo, in order to focus on his karate school and other disagreements. Many years later, starting at the 2007 Power Morphicon convention, he began making convention appearances with other former cast members. He has since appeared at Anime Expo 2009 and Power Morphicon 2010.
