Galactic Frieza Army

The Planet Trade Organization (or World Trade Organization, occasionally referred to as just Frieza's Army or Frieza's Force) is the organization apparently run by King Cold and his two sons, Frieza and Cooler (Cooler only if movies are counted as canon). The planet trade organization employs and enslaves powerful races such as the Saiyans, to take over suitable planets so that they can be sold to the highest bidders. For unknown reasons, King Cold is not known by the organization as its leader.undefinedThus, it could be said Frieza is its true official leader (Cold being the owner and Frieza being the manager). The organization has never been given an official name, and it should be noted that "planet trade organization" is a name used just so there is a term for this group. However, Krillin does refer to the organization's members as belonging to the "planet trade."

History
Soldiers of Frieza's army combat Bardock's assault during the Genocide of the Saiyans

It is never stated when this organization began or any detail of its origins. All that is known is that it is apparently led by King Cold and his sons. Many formidable races are forced into the organization with the threat of their own planets' destruction if they do not comply. With their great power, King Cold and his sons apparently held a giant iron fist over the galaxy, controlling almost all planets under one giant dictatorship, and use fear and power to get races to comply. Frieza alone is shown to be in control of at least 79 planets, and Cooler in control of at least 256 planets with no mention of how many King Cold owns. They are also shown destroying planets that they believe are not suitable for sale (Cooler states in his debut that he has several planets to destroy by the end of the day, and Vegeta and Nappa's reason for destroying Arlia is because it was unsuitable for sales). No other leaders of this organization are ever shown, if any for that matter. The organization seemed to have officially ended with the deaths of King Cold and Frieza by Future Trunks in Age 764, and Cooler's death by the hands of Goku and Vegeta a short time later, thus bringing peace to the galaxy.

Saiyans Invasion on Earth
When Raditz came to Earth to get Goku, he trigger everything and thus the beginning of the Z Fighters vs. the Planet Trade Organization.

Battle on Namek
Frieza had brought his forces to Namek in December of Age 762 in order to use the Dragon Balls to wish for immortality. However, the Z Fighters coincidentally came to Namek at the same time in order to wish their fallen comrades back to life after they were killed in the battle against the Saiyans on Earth. Vegeta also travels to Namek to use the Dragon Balls with the same intention as Frieza, immortality. In the ensuing battle, all of Frieza's forces are killed, and is left alone to battle against Goku, who had become a Super Saiyan after Frieza had murdered Krillin. In a last ditch effort, Frieza tries to blow Namek up by destroying the core, and after a continuing fight, Frieza is cut in two by his own attack, and Goku leaves him for dead. Namek explodes minutes later, but Frieza survives.

Attack on Earth
Frieza is found near dead in space by his father, floating amongst the debris of the fallen Planet Namek. He is taken on board the ship and King Cold's scientists successfully repair Frieza by adding cybernetic attachment to the slain tyrant. Upon awakening, Frieza orders a course for Earth to receive vengeance on Goku, but continues to be haunted by the stern eyes of the Super Saiyan, fueling his rage. Roughly a year following his defeat, Frieza and his father arrive on Earth, only to be greeted by the time traveling Future Trunks who, much to the enjoyment of Frieza, states that he will kill them. Trunks proceeds to transform into a Super Saiyan, slices Frieza into bits with his sword, blasts King Cold through the chest, and blows up Frieza's ship with relative ease. This is evidently the end of the Organization, with the deaths of its leaders. It is unknown what happens to the thousands if not millions of races enslaved or involved.

End of the organization
After Porunga tells everyone that Goku is still alive and will return to the earth by his own means, Vegeta uses the spaceship constructed by Bulma's father and leaves for outer space in search of Goku. On his way, he finds the last remaining soldiers of Frieza and kills them.

After his failure and horrible defeat on Namek at the hands of Goku, Frieza drifted throughout space unconscious and near death. Fortunately for Frieza, his father King Cold learned of his defeat and searched through space hoping to find his son still alive. When Frieza was found, he was pieced back together using mechanical parts. Frieza then only had one thing on his mind... revenge. A short time later, Frieza and King Cold arrived on Earth, aiming to kill Goku and destroy the planet. However, this would be interrupted by the time traveling son of Vegeta, Future Trunks. Almost effortlessly, Trunks killed Frieza and his father, King Cold, thus putting an end to their terrible reign over the universe, but not before destroying their spaceship and killing all their soldiers. Goku then returned to earth, was given the information about future events, and peace was restored.

Some time later, Cooler, who apparently had just heard about his brother's death (he apparently had no knowledge of his father's death as well), came to earth looking for revenge. However, he proved to be no match for Goku's Super Saiyan power, and just like his father and brother, was defeated. He managed to survive and he too was saved by the use of mechanical parts, only he was saved by the Big Gete Star, which turned him completely metallic. After attempting to destroy New Namek and use it for fuel, Goku and the Z Fighters arrived to stop the threat. Once again it was Goku and Vegeta who defeated and this time finally killed Cooler.

Years later during the special, ''[http://dragonball.wikia.com/wiki/Dragon_Ball:_Yo%21_Son_Goku_and_His_Friends_Return%21%21 Dragon Ball: Yo! Son Goku and His Friends Return!!]'', the twin brother duo of Abo and Cado, old henchmen of Frieza, arrived on Earth and fought Trunks and Goten. After fusing into Aka, Goku eventually stepped in and defeated the duo. After their defeat the two reformed and joined the good guys at Mr. Satan's hotel banquet before leaving earth to earn a fresh start. Thus, officially ending the Planet Trade Organization as we know it.

It's unknown how many members of the organization survive

Prior to the events of the computer game Dragon Ball Online, in Age 820, remnants of the planet trade organization attacked Earth. The Kikoukenjutsu Sword School, a martial arts school created by Trunks and Goten, aided in the struggle against the remains of Frieza's army.
