Frieza

Frieza (フリーザ, Furīza, lit. "Freeza") was the emperor of the universe, who controlled his own imperial army and was feared for his ruthlessness and power, but was taken out of power when he was killed by Mystogan & Goku. He was the descendant of Chilled, the second son of King Cold, the younger brother of Cooler, and the father of Kuriza. Frieza is the catalyst antagonist of the entire franchise, as it is his actions that led to Goku arriving on Earth. He was revived by Earth dragon balls, renamed Hit and all of his memories were deleted. He became a good friend of Mystogan and Earth's greatest assassin. Recently, he has been chosen to represent Universe 7 member of Team Universe 7 for the Tournament of Might.

Battle of Gods Saga
In the summary at the beginning of the film Frieza - after accidentally having been cut in half - is shown attacking Super Saiyan Goku with his "Last Emperor" technique, only for Goku to defeat him with an Angry Kamehameha.

While Goku is image training on his radish field, he closes his eyes and pictures that he is fighting Frieza, Cell, and Buu. The mental thought of Frieza attacks Super Saiyan Goku from behind, but Goku senses him and hits him in the face, defeating him. After Whis reveals Frieza's defeat when Beerus asks as to how Frieza is doing, Whis peers back in time to Frieza's fight with Goku on Namek, showing Beerus part of the fight between him and Super Saiyan Goku.

Resurrection ‘F’ Saga
After his death Frieza's spirit was kept imprisoned in Earth's Hell, with the Angels of Hell being the ones who were tasked with ensuring that he remained captive.[14] During his time in Hell, Frieza's spirit retained the appearance of his Mecha Frieza state and was left trapped inside a cocoon. Contained in a cocoon in Earth's Hell, Frieza dreamed of his defeats at the hands of the Super Saiyans, Goku and Trunks, but soon woke up to the sight of the Angels of Hell. However, over fourteen years after Frieza's demise, his two of Frieza's men, Sorbet (commander of Frieza's army) and Tagoma (elite soldier), collect all of the Dragon Balls with the aid of the Pilaf Gang and resurrect him, and he is revived as he was just before his death, as Mecha Frieza and in pieces. Sorbet and Tagoma collect all of the pieces save for his right eye which is found by Pilaf, who hands it to Sorbet just as he and Tagoma are about to leave. On Sorbet's spaceship they put the organic parts in a Medical Machine, Frieza's body is regenerated and he reverts himself back into his first form completely free of his cybernetics. As he recovers inside the chamber Frieza dreams of his first defeat by Super Saiyan Goku, and angrily wakes up, shaking the entire ship.

He was then introduced to Sorbet and Tagoma while they explained to him how they brought him back to life and they could have brought King Cold back to life as well but Frieza suggested that there was no need for that, and suggested he would need to wait for his vengeance against the Saiyans, he announces to his soldiers that he will not be satisfied until the Super Saiyans (Goku and Future Trunks) have both been killed. Tagoma then suggests that Frieza put his grudge against the Saiyans behind him and focus on reconstituting his empire. Taking this just about as well as expected, Frieza quietly telekinetically blasts Tagoma out through the window, expressing disappointment at the cowardice and insolence the Frieza Force has been reduced to.

Sorbet preventing other deaths, activates the ship's energy shields. In the anime angry at Tagoma's suggestion to leave the Saiyans alone, he shot Tagoma with ki blasts instead of killing him because it would be considered boring to kill him quickly. Frieza is then informed by Sorbet that Goku's power has surpassed that of even Majin Buu, which is far more than Frieza could have imagined. But due to him being a prodigy, Frieza believes that through four months of serious training, he will be able to reach a level of power high enough to wipe out the Saiyans in the blink of an eye, in the movie and manga claiming he will be able to raise his power level from 530,000 to be 1,300,000.[8] He decided to train himself for four months in order to pull out his potential. For the next four months Frieza trained, sometimes using Tagoma as a training partner, during training sessions with Tagoma, Frieza would beat him within an inch of his life and then having him go to heal up for the next days training, allowing Frieza to both get stronger, and master his torturing-type fighting style; which would allow him to fight Goku for as long as possible without killing him, in order to cause the Saiyan as much pain as possible.

After all that time passed, Frieza and his forces eventually reach Earth and he gets excited about exacting his revenge on the Saiyans. As they are about to land Frieza begins laughing gleefully at his chance at revenge. After landing on Earth, he fires a Death Beam at North City, completely wiping it out, and then Frieza encounters the Z Fighters - who have gathered to try and resist him. Frieza becomes irritated upon realizing that Goku has yet to arrive when he recognizes Krillin as the person he killed on Namek. The tyrant scornfully remarks that the Dragon Balls can revive the powerful and the pathetic before receiving some scathing remarks from Bulma, who had never seen him in person until now. Bulma pleads for some time so that Goku to arrive, but he gives them only ten seconds. Not interested in fighting without his nemesis, Frieza has his army of 1,000 soldiers engage the Z Fighters, when Sorbet attempts to give orders to the soldiers Frieza flicks him away and instead has the soldiers all aim for Krillin as a joke - offering a planet to whomever kills him.

Frieza comments on Gohan's abilities as a fighter, nothing with disgust that the boy shares his father's morals. As the fight draws on, Frieza dismisses his troops as a disgrace to his name and threatens to kill Sorbet as punishment for his poor leadership, prompting the diminutive commander to send Shisami into battle. The hulking warrior quickly pull Gohan into a bear hug in attempt to crush him, but Tagoma blasts the duo from behind in an attempt to kill the enemy's strongest warrior. Intrigued, the tyrant then agrees to appoint Tagoma as supreme commander of his forces, if he wipes out the Z Fighters. He then proceeds to watch the battle unfold until Gotenks arrives, the fused warrior injuring Tagoma before picking a fight Frieza - only to defuse shortly thereafter. Frieza notes Goten's resemblance to Goku, and Trunks resemblance to Future Trunks and grows angry at how the Saiyans have multiplied, ordering Tagoma to wipe them out. Frieza tells Sorbet that the Super Saiyans are more fearful out of recordings.

Shortly afterwards, Frieza is approached by Captain Ginyu who has switched bodies with Tagoma while he was feeling pain on the ground. The captain explains his hardships throughout the years from being swapped into the body of a frog to arriving on Earth to Frieza's return. Frieza is happy that Ginyu is alive and once more in his service, but is unimpressed by Ginyu's fighting pose, and asks him to be useful and wipe out the Z Fighters. Frieza watches with glee as his faithful servant decimates the Z Fighters, noting that he is stronger than Tagoma was. However, Ginyu is defeated when Gohan transforms into a Super Saiyan, with Frieza expressing surprise that Goku's son was capable of obtaining the form.

Though Gohan decides to spare his opponent, Frieza recalls that this scenario is identical to the last part of his battle with Goku on Namek and snaps, flying down to the battlefield in his hover chair. Enraged, he dismisses Captain Ginyu and attacks Gohan with Death Beams whilst telling him to scream, beg for mercy, and run. After Gohan succumbs to his injuries and falls to the ground, Frieza attacks with a finishing Death Beam, suddenly, Piccolo jumps in the way of Frieza's attack - taking the full brunt of it - and protecting Gohan.

Frieza finds Gohan when he cries for Piccolo very amusing and decides to amuse himself and when Bulma finally talks to Whis, he disallows Sorbet to kill her at the moment in hopes that she might bring Goku to Earth. When he does not come right away, Frieza allows Ginyu to fight and kill Goku's friends so that he can be entertained at the least, but then Gohan stands up to Frieza and powers up into his Super Saiyan form once more to protect everyone, but the power-up eventually tires him out completely and Frieza once again decides to end his life. Shortly thereafter, Goku and Vegeta appear on the battlefield, the former having used Instant Transmission to return to Earth. Goku quickly blocks the Death Beam before rounding on Frieza, the latter explaining how he returned to life whilst describing his excruciating experiences in Hell. He blames Goku for the suffering he had endured since their battle on Namek and states his desire for vengeance. Vegeta then kills Ginyu, causing the villain to recognizes the Saiyan Prince's increased strength, though he promises to kill him once Goku is dead. After talking about their recent training, Frieza decides to transform into his final form from the start to avoid making mistakes again and prepares himself to fight, his transformation vaporizing the rest of his soldiers in the process, leaving Sorbet as the sole survivor.

They start their fight in the ground after powering up and then power up again during close combat. Frieza actually thanks Goku for making himself train to fight him at this level but then gets angry again and plans to kill Krillin and Bulma with Ki blasts but Goku and Vegeta show up at the last minute and deflect them (Vegeta did this because Goku was pinned to the ground by Frieza at the time). Then they resume their fight and they take it all the way above the clouds. Frieza told Goku he attacked his friends so he can fight Goku at his angriest but Goku refuses to as well as him destroying the Namekian Dragon Balls. After being beat around, Frieza fires a Golden Death Ball at Goku and he uses a Kamehameha to collide, causing an explosion. After a Ki blast barrage conflict, Vegeta shows up and fights Goku which impresses Frieza and he questions his loyalty to him, though Frieza fires a blast at the two and tells Vegeta that he wants to fight Goku first. After he became irritated by Vegeta's continuous clapping, the Saiyan decides to  take on the tyrant himself only for the two of them to negotiate for them to fight each other after Frieza kills Goku. In the manga the two fight and Goku has the advantage he than goes on to blast Frieza with a Kamehameha, prompting the tyrant to announce that he is soon going to reveal his further evolution. Frieza then witnesses Goku transform into his Super Saiyan Blue form.

Frieza tries to knock out Goku from behind to gauge his power, but Goku catches this attack with his fist, prompting Frieza into finally transforming himself into Golden Frieza, despite his own warnings, feeling honored to be fighting close to the Saiyan's god. After saying goodbye in advance, Frieza re-proceeds to fight Goku and he had the upper hand at first but Goku blocked all of Frieza's upcoming energy attacks which results in an energy clash that lasts a while and results in a blinding explosion and both combatants are still in their prime. As Beerus and Whis show up for their dessert, thanks to his new exceedingly high power, Frieza once again gains the upper hand against Goku and after comparing how long it took to reach their new forms, Frieza decides to kill Goku immediately and his friends too so that he won't be lonely in Hell. When he spots Beerus, however he becomes frightened and frustrated that he might interfere but Beerus told Frieza to do as he pleases. Frieza then decides to continue his revenge and kept pushing him further and further, leaving Goku exhausted.

Frieza then strangles Goku with his tail and punches him in the gut and head repeatedly until Goku bit his tail forcing him to let go, yet Frieza still had the upper hand and knocked him down again. He then explains again why he hates Goku for his actions back on Planet Namek and tries to kill him with his energy attacks but for some reason Goku kept surviving them all. They were almost interrupted by Vegeta, who wanted to kill Frieza for Goku but he insisted that he almost has him. Goku also warns Frieza about his form's downside but he ignores his warnings and decides to wrap things up, with both combatants using every last bit of power they have left. At first, Frieza seemed to be dominating again, not even allowing Goku to drown to death, until Goku's prediction started to come true: he burns more power and stamina than his body can supply and didn't regulate it before he decided to exact his revenge. Due to his massive drop in power and stamina Goku knocks him away with Super God Shock Flash in the movie, and a forehead punch in the anime. Goku then suggests that Frieza leave so that they can have a rematch later, however Frieza signaled to have Sorbet shoot Goku straight in the chest with his ring. He then repeatedly kicks Goku and explains his weaknesses while doing so: his strength makes him careless. In the movie he asks Vegeta to finish Goku off - offering to make him supreme commander, though Vegeta declines and begins to fight Frieza. In the anime he was about to kill Goku once and for all when Vegeta attacks then Frieza dodges it.

When Vegeta tells Krillin to give Goku a Senzu Bean, Frieza tries to kill him with a Death Beam but Vegeta blocks it and it ends up killing Sorbet. Frieza hardly believes that Vegeta could kill him now, but he too, turns into a Super Saiyan Blue, which frightens Frieza at first. Frieza tries to hit Vegeta with a lot of Ki blasts but he was never fazed by any of them due to Frieza having lost most of his power. After a bit of big talk, Vegeta beats up Frieza and the tyrant then reverts into his Final form. Before Vegeta could kill Frieza, however, Frieza blows up the Earth and kills Vegeta and everyone and everything on Earth, including Pan, Videl, 18, Marron, Chi-Chi, Majin Buu, Mr. Satan, and Dr. Brief and Mrs. Brief. Stated by Beerus and Whis, they stated that Frieza survived the destruction thus is floating in space, preparing his next move. However, the event was undone by Whis' Temporal Do-Over technique and Goku turned into his Super Saiyan Blue God form and charged and launched a Kamehameha strong enough to destroy Frieza and sent him back to Hell before he can destroy the Earth, although not before Frieza yells a curse at Goku. Once back in Earth's Hell, he was forced to watch the angels of Hell dance and sing while strapping a cocoon again, much to Frieza's chagrin.

Everyone protests because Frieza is as likely to destroy them rather than help them. Nevertheless, Goku insists he and Vegeta can stop Frieza should he get out of control. Goku convinces King Yemma to have him escorted to Hell where he finds Frieza strung up in his cocoon. Frieza wonders why Goku is there, and figures he is planning something when Goku asks Frieza how he would like to get out of Hell for a bit. After telling Frieza about the Tournament of Power, he cuts the cocoon down, liberating Frieza. Frieza admits he is intrigued, and asks Goku if it would inconvenience him if he said no. Goku admits it would, so Frieza says no. Goku then walks away, and Frieza quickly claims he was joking. Frieza tells Goku to use the Dragon Balls to revive him, enticing Goku by claiming he can become even stronger. Frieza powers up to his golden form, and Goku tells Frieza that he really is the most evil being in the Universe to exploit his weakness like that. Goku tells Frieza the winner will get to use the Super Dragon Balls, and that he can use those to resurrect himself should he win. Frieza remarks that doesn't guarantee his revival even if they win, and says the Earth Dragon Balls will be fine. Goku promises to revive Frieza, and so Frieza agrees to join Team Universe 7. Goku goes to see Fortuneteller Baba, and asks her to bring Frieza to Earth for 24 hours. Baba is reluctant to do this, but does as Goku asks since the fate of their Universe is at stake. Frieza arrives, and he and Goku greet each other by punching each other in the guts. Assassins from Universe 9 appear to assassinate Goku and Frieza, who powers up to Golden Frieza and begins killing the assassins. Frieza reveals that he learned to maintain his stamina by mental concentration via imagining killing Goku. Frieza is hit by a Energy of Destruction but quickly gains control of it and hits Goku with it. He uses a communicator device from one of the assassins to talk to Sidra and Roh. Frieza offers them a bargain: they make him a member of their team and he will perform well, as he doesn't want to be collateral damage if Universe 7 is erased and offers to kill Goku to ensure his team doesn't win. As the two gods argue over this, Beerus and Whis show up, and Beerus suspects Frieza is plotting against them, though Whis thinks he may simply have been trying to get intel on other universes. Frieza notes to himself that this tournament is the perfect opportunity to manipulate the gods of the many universes, and thinks to himself that Beerus will not be in charge for long. After Beerus frees him, Goku asks for a quick spar with Frieza on the condition that whoever lands one punch wins. Both punch each other in the face and knock each other out cold and Beerus declares they are evenly matched. Frieza is taken to the rest of the team.

As soon as he arrives, all the other members look at him suspiciously while Beerus prevents him from doing anything stupid to which Frieza tells him he knows. Vegeta then makes a comment about his halo but Frieza can vexer him that he will give him one. As the team leaves, Whis tells them to join hands so he can get to the tournament, Frieza notices that Vegeta does not want to give him the hand to those Frieza insignificant that the prince of the saiyan is afraid of Him, annoying Vegeta who passes in Saiyan beyond God until Beerus screams that he had to work as a team. Beerus grabs Frieza's arm instead of Vegeta and they depart for the World of Void for the tournament.

Frieza and everyone are transported by Whis to the World of Void, there he meets the other universe fighters (particularly Frost). Like Goku, Vegeta, 17 and 18, Frieza ignores Gohan's strategy and runs off to fight on his own; ki blasting an Unknown Fighter at point blank.
