In 1992, during the production of Power Rangers, the release of Saban Entertainment's new show, VR Troopers, American adaption of the Japanese Metal Hero series was finally complete. Jason David Frank, who played Tommy in Power Rangers in many different seasons was first offered the position of Ryan Steele, the main character, and the original name for the series was Cybertron. Frank was also going to be the only character.
However, Frank instead went on to become the Green Ranger and Brad Hawkins was given the position as the lead actor of VR Troopers along with Michael Calvin Bacon and Sarah Brown.
