Three Hundred Years ago a small group of Saiyans ventured into the Milky-way galaxy on a mission of intellect rather than conquest. Forming a small colony, they studied early humanoids and how some were able to harness Ki to a limited degree making them stronger than normal humanoids. These saiyains eventually died off with time, leaving some strange humanoid fossils that when studied by Dr Gero and the Red Ribbon Army which discovered the potential of utilizing alien DNA in weapon projects.
