The Bosquito (ボスキート Bosukîto) is a powerful, dangerous, alien lifeform feared across the universe. The Gransazers were originally created to counter it when it came to Earth. Despite being wiped out in the war that destroyed Earth's ancient human civilization, Belzeus claimed that the humans were descended from the Bosquito as a way to encourage the Warp Monarch to finish the global genocide they started long ago.
