Tagoma's History
Background
In the anime, Tagoma only encountered Frieza once prior to his revival, noticing Frieza speaking to Dodoria and Captain Ginyu at one point in the past. Tagoma recalls this event just prior to helping resurrect Frieza.
God of Destruction Beerus Saga
In the manga, on Planet Frieza 17, Tagoma informs Sorbet that the army's second strongest in the Frieza Force ship was blown up by an unidentified force. After hearing this, Tagoma and Sorbet set off to find the Dragon Balls to resurrect Frieza.
Golden Frieza Saga
Tagoma and his accomplice, Sorbet, are both elite soldiers in the Frieza Force, working under Frieza. Years after Frieza's death, the two come to Earth to collect the Dragon Balls and revive their master. He seems to be Sorbet's favorite henchman, as he cares about him and prefers him over the jealous Shisami, who seems to be on a hidden-competition with him.
Tagoma is one of Sorbet's finest fighters, and is described by his superior to be a fighter on par with the late Zarbon and Dodoria. When the Frieza Army forces have been outmatched in putting down an uprising in Planet Frieza 448, Sorbet, who is now standing-in-leader of the Frieza Force, has decided that there is no escape. Sorbet decides to revive Frieza so he can reorganize the empire, and calls Tagoma to join him on a two-person spaceship to Earth. During the operation to revive Frieza, Tagoma shares his concerns about it with Sorbet, emphasizing that Frieza was an evil dictator, who they may just be better off without. Sorbet agrees, but says that with the army's current achievements and weakened power, they have no other choice.
They scout the planet and see that the Pilaf Gang is collecting the Dragon Balls. Tagoma and Sorbet quickly head to Earth before they find the seventh Dragon Ball. The final Dragon Ball to be retrieved is in the ocean and Tagoma is sent down to retrieve it. Tagoma, Sorbet, and Pilaf Gang go to the desert to summon Shenron to revive Frieza. After Shenron states that he cannot revive Frieza due to him being cut into pieces many years ago, Tagoma suggests that they use the recovery chambers they have built before. On Sorbet's spaceship, Frieza is quickly revived and made whole. Tagoma is briefly reintroduced to Frieza as he forgets who his soldiers were. Frieza starts to describes his plan to avenge his fall at the Saiyans.
When Tagoma advises Frieza to ignore the Saiyans, Frieza fires several Death Beams through his limbs and leaving him sprawled out on the ground in pain. Frieza decides to train for four months in order to become strong enough to defeat Goku. Tagoma is selected to be Frieza's training partner by Sorbet. Tagoma would get beaten, until being on the verge of death. He would then use the regeneration machine to recover and continue training with Frieza every day. Tagoma's and Frieza's power significantly increased doing this. After four months of training, Tagoma arrives on Earth with Frieza and the rest of his army.
When Frieza and his forces arrived on Earth, several soldiers face the Z Fighters and are defeated. In response, Sorbet sends Shisami, who fights Gohan and attempts to crush him in a bear hug. In an attempt to wipe out the enemy's strongest warrior, Tagoma fired a ki blast that kills Shisami and critically injures Gohan (who is soon revived by Piccolo's kiai to the chest and a Senzu Bean). Despite being scolded by Sorbet, he intimidates his commanding officer and explains his recent coldness and personality change. Tagoma then makes a deal with Frieza saying that if he kills the resistance, Frieza would allow him to become commander to which Frieza agrees, also stating that he would give him a planet of his choosing.
Tagoma then proceeds to approach the Z Fighters, and powers up to face them. He tells all of the Z Fighters to come at him together. Tagoma is prepared for his first fighter so Piccolo steps up. Piccolo charges and punches him in the head but Tagoma is unfazed by the attack. He then rips off part of Piccolo's arm and gets several blows on him until Gohan aids Piccolo. However, Tagoma is unfazed by this, and states that thanks to his training under Frieza, "refined" attacks will not be as effective on his "body of steel".
Super Saiyan Gotenks charges in from Capsule Corporation and headbutts Tagoma in the crotch. Tagoma is lying on the ground in pain as Frieza orders him to wipe out the Z Fighters. All of a sudden, frog Ginyu comes up to him and writes "Change" in front of Tagoma in an alien language. Tagoma reads the word and suddenly changes bodies with Ginyu, trapping Tagoma in the body of a Namekian Frog. As of now, Tagoma's fate remains unknown.
