Bio Hunter Silva

Bio Hunter Silva (バイオハンター・シルバ, Baio Hantā Shiruba) - A robot from Bio Star programmed to kill anything with the Bio Particles. He was given half of the Bio Particles. He can also fire arrows from his elbow. He became maniacal and with his mecha, Balzion (バルジオン, Barujion), helped destroy Bio Star. He armed himself with the bio killer particles (which killed Yellow Four I), but his shots were not able to kill any of the Biomen probably due to their upgrade, and used them to power up his robot as well. He is enemies with both Biomen and Gear (who wanted to steal Balzion for their own use). He killed Mason using the arrows that he fires from his elbows. He was killed when Balzion was defeated by a sudden charge of Bio Energy from the Bio Robo.

He returned in Kamen Rider x Super Sentai: Super Hero Taisen as a member of the Dai-Zangyack, a villain alliance lead by Captain Marvelous (Gokai Red) for the invasion of the Kamen Rider universe, under the new name of Rider Hunter Silva (ライダーハンター・シルバ, Raidā Hantā Shiruba). He also possesses the means to fuse the Gigant Horse of Dai-Zangyack with Dai-Shocker's Crisis Fortress into a Big Machine mech. He later was destroyed by GokaiGalleon Buster Tajadoru Charge when Gokaigers taking the form of OOO Combo Gokai Changes.
