Enigma

Enigma is the mysterious mentor to Robby, Galactic Force Silver. Assumed to be a Deltraxian scientist who worked on the Stallion Buckle prototype before it was lost to the far reaches of space, Enigma contacted Robby after the latter found the device and used it to ward off a group of Darkenites who attacked him. He became Robby's commanding officers, guiding him during battles and ordering him around. He initially refused to let Robby join the Galactic Force rangers, forcing him to hide his identity and to never work with the others unless absolutely necessary. However, Robby accidentally revealed his identity to Joshua, Galactic Force Red, angering Enigma, who threatened to disable the Stallion Buckle when Robby decided to join their team. However, he was quickly convinced otherwise, and he (relunctantly) allowed Robby to join the other seven rangers, staying on as his technical advisor. However, he began to guide him less and less as the series went on and essentially vanished prior to the final battle for unknown reasons. He is voiced by Troy Baker.
