This article is about the pure good half of Innocent Buu. For the original fat form of Buu, see Innocent Buu.

Good Buu (魔人ブウ:善; Majin Bū Good),[4] is the result of the Innocent Buu using fission to split into good and evil halves. He would go on to become a member of the Z Fighters and live with Mr. Satan. After the battle against the pure Majin Buu, Buu is referred to as Buu instead of Majin Buu and to the world he becomes Mr. Buu.



Due to Innocent Buu splitting into Good Buu and Evil Buu, Good Buu became a "different life-form"[11] from the original Kid Buu and Innocent Buu forms, and lost many of the unique capabilities of the original Majin.

He became an entity of pure good, due to Innocent Buu's evil manifesting as Evil Buu, he lost the ability to absorb using his body and needed to turn others into chocolate in order to accomplish an "absorption", he also lost his eternal life and became capable of dying of old age,[7] and he no longer needed to hibernate for incredibly long periods of time - instead entering an unwaking sleep for a brief period of time. He also lost a great majority of the power he once held to Evil Buu.


Good Buu is an entity of pure good, and is very kind, caring, and playful. Once he was absorbed by Evil Buu, his playful and childish traits manifest in Super Buu and Kid Buu respectively. During his second battle against Gotenks, Gotenks was preparing the Super Ghosts of his Super Ghost Kamikaze Attack for battle. Piccolo showed Gotenks that Buu had already regenerated from the last Super Ghost attack. Super Buu was also lying on his stomach, drinking a soda (though it looked like a milkshake) and reading a magazine, much to Gotenks' fury and embarrassment. Also, when Goku and Vegeta were preparing for battle, Kid Buu was sleeping (as Buu only needs a little time to rest), much to Goku's surprise. More importantly, due to his connection with Mr. Satan he had influence to stop him from killing the former as Super Buu and later Kid Buu. For this reason, he also responded to Videl's request to be patient due to being Mr. Satan's daughter; though it wasn't enough to stop him from killing her. While mildly annoying to Super Buu, it infuriated Kid Buu enough that he spat him out as soon as he was able to. Despite his good nature, it is shown in Dragon Ball Super that when he is hungry, Good Buu can be foul tempered and grumpy like when he interrupted Mr. Satan's press conference and is also shown to be quite gluttonous as he selfishly refused to share one of his pudding cups with Beerus. However these negative traits could be attributed to his childlike personality.

Majin Buu Saga

Main articles: Majin Buu Saga, Fusion Saga, and Kid Buu Saga After taming the Innocent Buu, it seemed that the world is saved by Mr. Satan. All is well until the two gunmen Van Zant and Smitty arrive with the goal of taking on Buu and shoot Bee as he is playing with Buu. This causes Buu to become more enraged than he has ever been, but this anger is quelled by Mr. Satan's disposing of the two gunmen and taking Bee back to Buu to be healed. The situation seems fixed as Buu rebuilds his house in the shape of Bee and Mr. Satan resumes his maid tasks. Buu now seems fully changed, playing with Bee and even asking Mr. Satan to sit and eat with him. Mr. Satan even destroys the fake pictures of Buu defeated that he had taken. This lasts until the gunman who shot Bee returns and shoots Mr. Satan in the chest. Buu is able to heal him but the pain of losing his best friend is so great that he struggles to control his anger. Finally, Buu loses control of his anger, and splits into Good Buu and Evil Buu. The evil leaves Buu in the form of a giant cloud taking most of his power with it, and Good Buu watches as the cloud takes form and becomes Evil Buu. A battle soon ensues between the two Buus, the Evil Buu dominates over the Good Buu. Good Buu is ultimately turned into chocolate, after Evil Buu reflects his Chocolate Beam, and devoured causing them to re-merge into one being, Super Buu.


Evil Buu triumphs over Good Buu

Though Super Buu is almost pure evil, Good Buu is still able to affect his actions slightly, preventing him from attacking Mr. Satan, Bee, and Videl on multiple occasions. He is later removed from Super Buu by Vegeta, and once the power of the Kais was removed from him, Super Buu reverted to the insane creature "created" by Bibidi, Kid Buu (the original Majin Buu). Although Good Buu is no longer connected with Kid Buu, his presence alone prevents the other Buu from attacking Mr. Satan and Bee on the Sacred World of the Kais until he is spat out.

"Me big Buu, why little Buu stronger?"
— Good Buu while fighting Kid Buu


Good Buu fights Kid Buu

Good Buu is extremely pleased to see Bee and Mr. Satan are still alive, and then steps in the fight to defend Mr. Satan, and even though Kid Buu is far more powerful, he is able to land a few good hits on him due to his increased strength. He holds Kid Buu off while Goku and Vegeta ready the Super Spirit Bomb to defeat Kid Buu. Good Buu and Kid Buu battle ferociously, neither one of them backing down, with both Buus performing many techniques, such as the Multi-Form, Chocolate Beam, and more, but Kid Buu is clearly stronger, toying with Good Buu during the fight. After a hard battle, Good Buu is defeated by Kid Buu and presumed dead, so Vegeta battles Kid Buu while Goku readies the Spirit Bomb. The Spirit Bomb is finally formed after much delay, but Goku is unable to launch it due to Vegeta being immobile, right next to Kid Buu.

Kid Buu prepares a final Planet Burst attack to kill Goku, when suddenly Good Buu appears again, not quite beaten yet. He and Mr. Satan rush into the battle, as Good Buu tackles Kid Buu, causing him to throw the attack without aim and misses, while Mr. Satan rescues Vegeta after Good Buu orders him to do so and gets him to safety. Goku throws the Spirit Bomb and after some struggle, the monster is finally defeated and the universe is saved. After the battle, Goku uses the Dragon Balls and wishes for no earthling to remember the havoc wreaked on the world by Majin Buu. In addition, in order to ensure that Buu not unleash a similar horror to Kid Buu again, Mr. Satan also forbade Good Buu from either getting angry ever again or at the very least not unleash his anger. Soon after, Good Buu is given the name Mr. Buu, and joins in the celebration of his evil counterpart's defeat at Capsule Corporation.

Good Buu and Beerus face-off

Six months after Kid Buu's defeat and being erased from the Earthlings' minds, Buu interrupts Mr. Satan's press conference at the Satan House furiously stating he was hungry. Without having a clue who Buu is, Mr. Satan took advantage of this and told the world that Majin Buu is a space soldier that went to Earth to be trained by him. After storming out, Mr. Satan leaves his conference to calm Buu down and give him a massage.

Buu attends Bulma's birthday party on a cruise ship. Buu starts to eat all the food before the party starts and Bulma gets angry over this. Mr. Satan tells Buu that Bulma has a massive feast specifically for him and that he needs to wait. Buu continues to eat throughout the party. When Beerus is on Earth, he is interested to try pudding which Buu had enough of. Beerus asked for at least one to taste it but Buu refused to give him one, angering Beerus. Mr. Satan tries to tell Buu to give him one but Beerus and Buu blasted him away for interrupting. Buu and Beerus faced off: Buu gave hits to Beerus but they simply didn't have any effect on him. Buu was tossed around by Beerus' speed and was blasted into the ocean. Buu tries several times afterward to hit Beerus but continues to get taken out. Buu later watches the battle between Super Saiyan God Goku and Beerus.

Good Buu falls asleep

Buu is chosen by Goku to take part in the tournament between Beerus' team and Champa's team. The day of the tournament, Majin Buu is taken to the Nameless Planet along with his friends in Whis' box. After two hours and forty-five minutes, they arrive on the planet. As soon as they get there, the written test to participate in the tournament, requested by Vegeta, begins. In the manga, Majin Buu fails his test, even spelling his name wrong, because he has not done anything like that before. In the anime, he fell asleep during the exam, automatically failing it by default. Since he failed, he is not able to participate, so he sits with his friends and watches the first battle against Goku and Botamo.

Buu finally woke up after the tournament was over and after the Omni-King showed and left and apologized to Mr. Satan for not being able to grant his wish. He then stated that when he fell asleep, he believed that he found incredible talent in Monaka. Buu later went with everyone else in the Cube and got to see Super Shenron before Beerus made his wish to make Champa's Earth just as hospitable as his to make him owe him one.

Afterwards, Buu joins in on another party, this time, he is ensured by Bulma that not even he can finish all of the food by himself.

During this time, he apparently also got his own fanbase, as Goku noted that Buu seemed to acquire a lot of adoring fangirls when going to the ring for selection. He also convinces Buu to use his magic to rig the selection so that Buu can fight Goten, and that Goku fights Uub. Goku also tells Vegeta and Buu in private that Uub is the pure good human reincarnation of Kid Buu, much to Buu's surprise. The tournament is later cancelled due to Goku and Uub's absence.

Other Dragon Ball Stories



Majin Buu meets Usagi Majin in Nekomajin

Majin Buu has a cameo appearance in Nekomajin, a short series of one-shot manga chapters by Akira Toriyama which takes place during the time period between Dragon Ball Z and Dragon Ball GT. Neko Majin Z's friend finds Buu just wandering around while going to Satan City after mistaking him for Neko Majin Z. Buu is surprised that Neko Majin Z's friend does not know who he is and breaks the fourth wall by mentioning that he is from the Dragon Ball manga. Buu displays his strength while Neko Majin Z's friend remains unsurprised and responds by saying that Neko Majin Z does stuff like that all the time (he also mentions how Neko Majin Z looks and acts similar to Buu). Buu leaves and tells Neko Majin Z's friend to call him to fight Neko Majin Z when he comes around. Shortly later, when Usagi Majin steals the source of Neko Majin Z's power, his friend calls Buu and tells him that Usagi Majin is "Neko Majin Z". Buu easily beats Usagi Majin and leaves, disappointed that "Neko Majin Z" was so weak.


It is explained in Dragon Ball Online that in Age 790, Mr. Buu finds and reads one of Mr. Satan's adult books, "Bob & Margaret", causing him to long for love. He creates a wife for himself called Miss Buu. The following year, Mr. Buu and his wife create a Baby Buu via the Love-Love Beam. It is implied that Buu's family continues to grow, and thus the formation of the Majin race on Earth in Dragon Ball Online.

Xenoverse 2

Majin Buu's house mysteriously becomes caught in a time rift and the Time Patrol is forced to investigate the anomaly that caused it. If the Future Warrior (Xenoverse 2) is a Majin, then at the beginning of the game they will be shown investigating Majin Buu's house and a cutscene showing Majin Buu reading Bob & Margaret will be shown. When Buu comes across a word he doesn't understand, he asks Mr. Satan (who was visiting) what it means, only for Mr. Satan to tell him he shouldn't be reading it and asks where he got it from. Majin Buu tells him he found it from Mr. Satan's room, causing Mr. Satan to request he give it back, but Buu stubbornly refuses and Mr. Satan gives up. Later on the Future Warrior learns that Majin Buu is lonely and inspired by Mr. Satan's relationship with his daughter, decides to create children of his own using fission. The Future Warrior can help by providing Majin Buu with food that will give Majin Buu the energy to create his offspring. If the Future Warrior is Majin, the size limit of Majin Buu's family increases to 10. The Future Warrior can also give food to Majin Buu's children in order to receive different items based on the Majin's color.


Manga and Anime

Good Buu is weaker than Evil Buu (and by extension the original Innocent Buu that they split from), but his power is still significant. He is shown to hold his own against Kid Buu better than what Super Saiyan 2 Vegeta did though is soon outmatched and defeated.

In Dragon Ball Super, Buu challenges Beerus who easily defeated him by whirling Buu around with his immense speed and blasting him into the ocean. Even though Buu had been attacked by Beerus several times, Buu continued to challenge Beerus, lasting longer than Gohan who is stronger than he is. This is because of his regeneration ability.

In the God of Destruction Champa Saga, Buu is the first chosen for Beerus' team by Goku for the Universe 6 and Universe 7 tournament because he thinks they could not win without having Buu part of their team. Vegeta asks why he would choose Buu since he lost in one hit against Beerus and Goku states that while that is true, Buu can become much more incredibly powerful when he fights seriously.


  • Ki Blast – The most basic form of energy wave.
  • Flight – The ability to fly with the use of ki.
  • Body Manipulation and Regeneration – Majin Buu has full control over every aspect of his physical make-up, able to stretch, shape-shift, liquefy, and otherwise manipulate his malleable body; useful as both an attack and defense and as a tool in absorption. He can also regenerate his body at a sub-molecular level, allowing him to survive virtually anything; however, he was unable to regenerate Frieza's Repeating Death Beams destroying Earth since it destroyed every atom of Buu. It is shown during the fight between Vegito and Super Buu that even his regeneration has its limits; after repeatedly being blow to bits and pounded into oblivion, Buu had to exert more and more effort to restore himself, at one point failing completely for a moment and leaving a gaping hole in his stomach.
  • Super Kamehameha - The more powerful variation of the Kamehameha. Having copied the technique from Goku before his fission, Good Buu is still able to use this attack. This attack was used in his fight against Evil Buu, who also attacked with the same move. However, Good Buu's attack was eventually overpowered.
  • Chocolate Beam – This is Good Buu's signature attack. It is a unique ability to change objects and living beings around him into inanimate objects such as sweets and milk. When Majin Buu expelled his evil and became the pure hearted Good Buu, he tried utilizing it to finish Evil Buu, but it failed and backfired causing Good Buu's downfall and the result of Super Buu. In the final battle against Kid Buu, Good Buu desperately tried to use the chocolate beam to defeat Kid Buu, but it was also unsuccessful. Named in the Budokai Tenkaichi video game series.
  • Impressive Slap – An attack used against the human boxer Pit Bull Pete. Named in the Dragon Ball Z Collectible Card Game.
  • Fission – In Age 790, after reading Bob & Margaret caused him to long for female companionship, Good Buu uses this ability to split himself, though this time into Mr. Buu and the first female Majin, Miss Buu.
  • Sleep – Good Buu sleeps for extended periods of time, when asleep it seems to be impossible to wake him up.
  • Love-Love Beam – A technique Mr. Buu and his wife Miss Buu used give birth their child Baby Buu in Age 790. It is implied that they used this technique several more times to create more children and their family to continue to grow resulting in the creation of the Majin race.

Forms and Fissions

Mr. Satan and Pan absorbed

In Dragon Ball GT, during the Baby saga, Buu absorbs Mr. Satan and Pan to have them hide from the Tuffle parasites. Due to Good Buu's differing nature from the original Innocent Buu, this is different from other absorptions, Mr. Satan and Pan are still conscious inside Buu and this does not change his appearance.
