The Human race is the most common of all races, they are the weakest, but biggest. The Human race is the people that live on the Earth. The female Humans are mostly the mothers for Saiyans because there arn't much female Saiyans and most the Saiyans had died in a crisis. The Humans have the power to fly and shoot energy beams, but onyl few can controll it. For Humans to controll their energy it takes long periods of time to do it, rather than Saiyans; they are born with the capabiltiy of doing with small amounts of practice compared to humans. With humans being a weaker race, they are the easiest to conquer. So the Humans of earth are protected by the Gaurdien of the Earth, either Kami or Dende, with out the humans knowledge. The Saiyans also help the Humans by fighting off the Conquerors.
