Robo Master of V-Stealth Robo and formerly an agent of Disaster for Kaiser-G until reformed and accepted into the MRR. He is a combat specialist and also a "survivor natural" like Taiyou. His past is unknown but it is believed he was involved in space exploration when he was a baby. He was the only survivor from an accident that happened in space where he was sent out in an escape pod and found by an exploration team. He was sent to an orphanage then captured by the Disasters. He was brainwashed and trained to be a warrior. Later on in the series, he and Kai were both assigned to space for International Hyper Rescue. (Source: Wikipedia)
