Cabba (キャベ 'Kyabe') is a Saiyan from Universe 6. He is a member of Team Universe 6 and is one of its strongest fighters, and a member of the Sadala Defense Forces.
Cabba is fair-skinned and of short stature and has a very slim build. Cabba's hair is black and spiky, with one bang hanging over his forehead, similar to Gohan's during the Majin Buu Saga and Tarble's in the anime. His eyes are narrow with large black pupils and his outfit has yellow straps, silver plating, a purple under piece, and a blue suit underneath with brown armbands, a brown belt, and purple shoes with grey soles. This is similar to the original uniforms worn by Saiyans before they were conscripted by Frieza. He appears to be a very young, teenage Saiyan, around 17 to 19 years of age, although he could be much older since Saiyans physically age at a much slower rate.
Cabba is a good-natured, polite, and humble Saiyan, but when in a fight his disposition changes to a serious, no-nonsense attitude. Contrasting the violent and arrogant nature exhibited by the vast majority of Saiyans from Universe 7, he speaks respectfully to everyone and prides himself as a protector of the weak. He is ashamed that Frost, once thought to be a close ally who he initially thought to have shared the same sense of justice; was not only a cheater but also a manipulative, cold-hearted space pirate lord who ended the wars he started to gain public support.
In spite of (as well as due to) his good nature, when Vegeta tried to provoke him into turning into a Super Saiyan by telling him that he would kill off all of Sadala, including Cabba's family, the young Saiyan became extremely angry and transformed, attacking in rage. After finding out this was a test, he calmed himself and developed respect towards Vegeta, even calling him "Master".
Due to his very polite nature, he has a very hard time making fun of others, and in fact, seems almost incapable of faking anger. This is seen when he tries to provoke Caulifla but does it in a very quiet, non-threatening way.
When he witnessed Universe 9 being erased, Cabba realized what he was fighting for and confronted Vegeta, telling him he will be eliminated from the tournament, showing that despite respecting his self-proclaimed mentor, he wanted to protect his universe even more. After being saved from Monna by Vegeta, who tells him to not forget his pride as a Saiyan and his promise to restore the erased universes, this helps Cabba to develop a newfound resolve that causes him to unlock the Super Saiyan 2 form.
Before the erasure of Universe 6, he solemnly wishes Vegeta luck on winning the Tournament of Power. After being restored by the Super Dragon Balls, Cabba is seen thanking Vegeta (unaware that it was Android 17, who was the ultimate victor and wishmaker).
Cabba is a Saiyan born in Universe 6 on Planet Sadala. Cabba was trained by Renso, and the latter was his captain. At some point in the past, Cabba fought alongside Frost to stop space pirates on the planet Mayonnai, a group Frost is the leader of in secret.
Dragon Ball Super
Universe 6 Saga
Cabba is selected to participate by Vados for Team Universe 6 to combat Team Universe 7. The day of the tournament, Cabba appears on the Nameless Planet with his four other teammates: Hit, Frost, Botamo, and Magetta. Vados is about to begin the written exam to participate in the tournament when Cabba catches sight of Vegeta and Goku and notices that they may be Saiyans. He goes up to them and asks about this and his thoughts are confirmed as they are impressed that he could recognize a Saiyan, noting there may be Saiyans in Universe 6. Cabba reveals to Vegeta and Goku that there are and he is also a Saiyan. Both Goku and Vegeta are shocked, and then Vegeta also comments on his garments, noting they resemble the style Saiyans wore before getting conscripted by Frieza's army. Cabba is questioned by Vegeta, as he wonders what planet the Saiyan resides in Universe 6. Cabba says that the Saiyans of Universe 6 live on Planet Sadala, the original Saiyan planet.
Cabba is curious as to whether or not Planet Sadala exists in Universe 7, but Vegeta explains that it has been destroyed due to an internal conflict between the Saiyans while further explaining the events that took place afterward. Goku then asks Cabba where his tail is, to which Cabba reveals that they had tails long ago, but have lost them due to the evolutionary process (in the anime, Cabba is unaware that Saiyans possessed tails). Vegeta wonders if the Saiyans of Universe 6 are still a "warrior race", and Cabba claims they are, except they fight evil instead of taking and selling planets. As Vados scolds them for not taking their seats, Vegeta asks Cabba if he could take him to Sadala when he is able to and assures him to not worry because the Saiyans of Universe 7 don't steal planets any longer. Cabba agrees to do so and tells Vegeta he will not hold back in their match.
Cabba takes the written exam of ten basic questions and passes it. However, Universe 7 is down by one fighter because of Majin Buu failing the written exam. He then watches the first match between Goku and Universe 6's first pick, Botamo. Botamo loses to Goku because Goku throws him out of the ring due to him not being able to deal damage to him. The next combatant for Universe 6 is Frost who fights Goku next immediately after. Cabba is surprised when he sees Frost transform into his "final form". When Goku transforms into a Super Saiyan, Cabba is asked by Champa if he knew Saiyans could transform but Cabba claims he never has seen or heard of anything like it before. Frost is able to beat Goku when a secret technique. When the next fight between Piccolo and Frost starts, Cabba sits back and watches the match between the two fighters. He is surprised when the fight is over and that Frost won. When Jaco asks the referee to check Frost because he detected something wrong about Frost, Cabba immediately objects, saying how he believes that Frost is a noble character and that he fought Frost himself, so he believes Frost won fairly. He is in complete shock when Frost reveals that he starts wars just to end them and buy war-torn planets at a very low cost. Cabba then watches the fight between Vegeta and Frost.
When the battle between Cabba and Vegeta begins, Vegeta notes that Cabba has the same stance as he does. As the battle commences, both Saiyans are evenly matched, and Vegeta is utterly surprised when Cabba prepares Vegeta's signature move, the Galick Gun. After both Vegeta and Cabba use their Galick Gun, Vegeta commands Cabba to transform into a Super Saiyan. Cabba responds by saying he doesn't know how to transform into a Super Saiyan and then asks Vegeta to teach him. Vegeta gets angry at Cabba for asking this question during their battle, he then turns into a Super Saiyan himself. Vegeta then begins to pummel Cabba and mock him as he does so. Cabba then attempts to surrender to Vegeta but this upsets Vegeta even more, and he says if Cabba surrenders, he will kill him and once the tournament is over, he will destroy Planet Sadala. Though Vegeta didn't really mean it, his words drew the line for Cabba, and he tells Vegeta if he destroys Planet Sadala, he will never forgive him and proceeds to transform into a Super Saiyan.
Cabba then launches at Vegeta and attacks him out of fury. Cabba eventually tries to punch Vegeta but it doesn't faze him. After this, Cabba loses the form. Vegeta then tells Cabba that the Super Saiyan transformation becomes possible through anger, and to never forget the anger. Vegeta immediately tells Cabba to transform once again, and Cabba does, realizes that Vegeta said those things to help him unlock Super Saiyan. Vegeta transforms into a Super Saiyan Blue immediately after Cabba transforms and tells Cabba about the newest Super Saiyan transformation, and that he too can obtain the transformation if he trains hard enough. Cabba simply marvels at the power Vegeta possesses and asks if he really can achieve the kind of power Vegeta has. While distracted, Vegeta knocks out Cabba with one punch to the abdomen, knocking him out. Vegeta tells Cabba to remember the feeling of the God Ki so he could transform into Super Saiyan Blue in the future. The referee then declares that Vegeta is the winner for the third time in a row. Cabba is then woken up by a pail of water, thrown on him by Vegeta. Cabba bows to Vegeta and praises him, but Vegeta does not appreciate the gesture and says that bowing to your opponent in battle is the same as giving up to your opponent. Vegeta then tells Cabba about the Saiyan pride and how it is the strength of the Saiyans. Cabba says that he will become as strong as Vegeta, but Vegeta says he wants Cabba to surpass him, but he won't let up so easily. Cabba tears up and thanks Vegeta for his kind words. Before Vegeta goes, Cabba tells Vegeta about how their king is a very strong and prideful Saiyan like him. Vegeta is interested and says he hopes to meet him someday.
