This story tells how he became the man he is today.
Ginyu used to work for Cooler as part of the Armored Squadron. But things went wrong after Ginyu and Salza fought over leadership over the Armored Squadron. He lost and was very humiliated, so he left the team in shame and quit working for Cooler.
It was then he was found by a person who cared about his loss.
???: I understand what you're going through. It must be painful to lose your honor.
Ginyu: Who are you? Why do you even care?
Frieza: I am Frieza, the brother of Cooler. You should work for me instead of him or that jerk, Salza.
Ginyu: Really.
Frieza: Yes. I am not like Cooler, even if he is my brother. You shall get the recognition you deserve. You need your own team.
Ginyu: Yes! I shall call it "THE GINYU FORCE"!
Frieza: Uhhh... sure. Are you in or out?
Ginyu: You got yourself a fighting team. Now I just need to find some members.
Frieza: Now go. Make me proud!
Just then, the first was Recoome. Who was found fighting on an unknown planet. He didn't have much brains, but Ginyu liked his strength.
Recoome: Uhh... who are you?
Ginyu: The name's Ginyu. How would you like to join my team.
Recoome: Uhh... ok.
The second was Burter. He was also wanted because of his great speed.
Burter: Who are you. What do you want with me?
Ginyu: I like your speed! Would you like to put it to good use and join my team?
Burter: Do I get to fight people?
Ginyu: Absolutely!
Burter: You got yourself a member!
The next was Guldo. Who invaded a planet with his psychic powers.
Guldo: This is fun. This planet's mine for the taking!
Ginyu: And you'll have a lot more if you join me. With your telekinetic abilities, we'll be unstoppable!
Guldo: Cool! I'll join then!
Last was Jeice. Who was attacked by none other than Salza.
Jeice: Go ahead. Get it over with.
Salza: You really thought you could defeat me? You fool! Now you die!
Ginyu: I don't think so!!
Salza: No, It can't be!
Ginyu: You leave him alone!
Jeice: Who are you.
Ginyu: I'm going to save you. But you must join me. We'll beat him together!
Jeice: Agreed.
Therefore, Salza was beaten and Ginyu got his dignity back. To this day, he continued working for Frieza and so did the others. Jeice and Burter also became best friends.
