Gem and his twin sister were captive phenoms of 'Alphabet Soup' along with Doctor K. The twins were the initial test pilots of the Ranger bio-suits. They befriend Dr. K even though she did not initially like them. When Venjix gets past Alphabet Soup and seeps into the world, the twins help get Dr. K out of the facility. They ran off to retrieve the classified Gold and Silver series bio-suits during a collapse and Doctor K believe them to be dead. They actually escaped when they morphed. Sometime later they were prisoners in a factory with other captives and met a blind woman believed to be Dillon's sister. When the Rangers were caught in a trap in Omega City, the Gold and Silver Rangers saved them and reunited with Dr. K and joined the team. Gem and Gema finish each other's sentences and are rarely apart from each other. They are both cheery and eerily optimistic, and have a fondness of making things explode. When Venjix took the Ranger Biofield information, he was able to delete the Mach Megazord, including Gem and Gema. They were gone for good until Dr. K was able to bring them back, after Tenaya had put a virus into Venjix's main computer and hacked into his system. After Venjix was defeated, Gem and Gema were recruited to the Eagle squad so they could explode all they wanted.
