Ginyu is the leader of the Ginyu Force and has a power level of 120,000. When brought to Planet Namek to rid of Vegeta, Krillin, and Gohan, he left his team to do the work as he protected the Dragon Balls. When Goku arrived, he fought Ginyu. But the fight grew as an overall equal match. Then when Ginyu changed bodies with Goku, he got more powerful and things got a bit confusing. Eventually, Goku found the chance to rid of Ginyu by crossing his Change Now path with a Namekian Frog. Goku then decided to let him go, but then Vegeta killed the Ginyu frog. Thus, most likely ending the reign of Captain Ginyu.
