Boo (ブウ, ), also known by the title Majin Boo (じんブウ (あく), Majin Bū (Aku); Viz "Djinn Boo"; Literally meaning "Demon Man Boo (Evil)") is the result of the pure evil Majin Boo eating the good Majin Boo.


Majin Buu Formed

Majin Boo undergoes a new evolution.

This new form of Majin Boo was born when the original good Majin Boo expelled all of his anger at the death of Mr. Satan.[3] With his struggle between the good and evil halves of his being now externalized, the two versions of Majin Boo fought. When the good Majin Boo attempted to turn the pure evil Majin Boo into chocolate, the pure evil Majin Boo bounced it back by breathing, causing the good Majin Boo to turn into chocolate and consumed by the other Majin Boo. This unique form of absorption resulted in the evil Majin Boo.[4]



Majin Boo's casual outlook.

Majin Boo's normal demeanor is quite villainous, often showing little to no more for his victims. Due to the merging of former Majin Boo, he has quite a mercurial, and inconstant personality. His casual demeanor shifts between the good one, and the pure evil versions. Where this Majin Boo can shift from his menacing face into a burst of either anger or even jovial emotions. Majin Boo shares one thing in common with his former self — that being his enjoyment towards destroying things and harming life.[5]

This is also seen in his pleasure from destruction where he eliminates the population of the Earth. His impatience is one of his characteristics along with having little to no remorse for life. Even taking pleasure in killing individuals for a enjoyment. In the anime Majin Boo has shown a big affinity towards sweets and a gluttonous personality.


This form of Majin Boo was a cross between the pure evil incarnation that had eaten the good incarnation. Unlike the fatter good Majin Boo, the evil Majin Boo was more physically built, toned and muscled, much like a proper fighter. His facial structure is identical to the evil Majin Boo, lacking any of the former good Boo's innocent face. As with the majority of Boo's incarnations, Majin Boo lacked a full set of fingers (though he possessed them in the anime).Physically, it could even be said he resembles an "adult" version of the pure Majin Boo. 

Unlike the two previous incarnations, he is shirtless, but his white gi pants remain the same. He has black and gold armbands and matching colored shoes.


Majin Boo is able to withstand the punishing effects of the Room of Spirit and Time without no difficulty affecting his body or mind. Majin Boo in this incarnation is stronger than both of his sources. He was able to battle the likes of Gotenks, enough to dominate them in their base forms, enough to put the likes of Piccolo in fear of his power, a Nameccian who assimilated with God. He was also shown to be able to manipulate his own anatomical structure like his former selves and is able to scream so loud that he can rip a hole into space, by creating a wormhole from the dimension of the Room of Spirit and Time to the living universe. In this form, Boo has very little patience and has extremely dangerous fits of anger, even possessing the power to rip through dimensional walls if he gets angry enough. Much of the full potential of this version of Majin Boo is based on the amount of individuals he has absorbed.

Ki Usage[]

Majin Boo like many characters in the series can manipulate ki. He is shown exceptionably able to sense ki unlike his previous incarnations.[6] He was able to sense traces sharply from the realm of God. Boo also possesses the basic skill to fly and is able to destroy mountains and trees with the pure force of the Air Dance Technique, in which he was able to travel from his house to the Castle of God in a brief amount of time.[7]


The basic Kikōha waves of Majin Boo have been to be pink and can amass them from his mouth, fingertips, continuously and was able to create enough of ki waves to eliminate the majority of the world's population with little, to no effort.



Majin Boo's absorption during his battle with Vegetto.

Majin Boo can use discarded parts of his limbs of his body to autonomously ambush a target through the expansion of the limb and enfold a target. Upon contact the flesh of Boo endlessly expands if they attempt to resist his flesh. Afterwards Boo can compartmentalize the target into smaller shapes that of his target and absorb them becoming one with his own being. The flesh of his body is strong enough to ensnare the strongest foes such as the strongest extraterrestrial races such as members of the Saiyan race like Super Saiyan 3 Gotenks and Gohan under the state of his Potential Unleashed. The power of Majin Boo increases through an unknown calculation but increases the combat power to the point where he can defeat even the likes of Gohan after only absorbing Piccolo and Gotenks. Among with gaining their powers it also affects his personality of the victim he absorbed.[8]

Piccolo Absorbed[]

This is a form that Majin Boo took briefly when Gotenks' fusion wore off. In this form, his primary power-source is Piccolo, and rather than the Metamoran vest, Majin Boo dons the weighted training gear that Piccolo wears over his gi. Beyond this, there are real physical changes, as he is similar to his Gotenks absorbed form in every other regard.

His combat strength, however, drops considerably. According to Gokū, Gohan, who had been weakened in the battle previously, would be able to handle Majin Boo easily. This weakness necessitated Majin Boo absorb Gohan, and progress to his next form.[9]

Gotenks and Piccolo Absorbed[]

What do you think, Gohan? My strategy succeeded without incident! Now, look! Wonderful, isn't it? This is that moment which will never come again, no matter the future — the birth of the mightiest of a Demon Man!

—Majin Boo to Gohan, Boo's Trick — Gotenks is Absorbed?!


Majin Boo after absorbing Gotenks and Piccolo.

This is the form that Majin Boo took when he absorbed Gotenks and Piccolo, prizing the former's power and the latter's intelligence. In this form, Majin Boo's body alters; he gains a slightly slimmer build, and more defined, humanoid facial features. His antennae, which had simply reached to the base of his neck before, extends towards his back, similar to Gotenks' Super Saiyan 3 hair. His attire also changes; while Majin Boo keeps the same pants and belt, with the Majin 'M' emblazoned on it that each form of Majin Boo possesses, he also wears the Metamoran vest; blue with yellow padding.

His power skyrockets, easily outstripping Ultimate Gohan Son Gohan and Super Saiyan 3 Son Gokū, to the point where the Old Kaiōshin believed only a fusion between the two fighters would be enough to end the Majin. Having absorbed Gotenks, and using him as his primary power source, Majin Boo is capable of utilizing Gotenks' techniques, such as the Continuous Super Doughnuts and the Super Kamehameha. In the anime, he showed himself capable of using Piccolo's Makankōsappō as well.

Majin Boo's mannerisms change in this form as well. He gains a far more eloquent manner of speech, as well as Gotenks' arrogance. He is more than willing to taunt Gohan, but is also more than aware of the limitations of this new form. In the English dub of the anime, Majin Boo had a penchant for psychological torture, bringing up Piccolo, Goten, and Trunks' disappointment in Gohan as a savior.

Gohan Absorbed[]

This is great! I'm much more powered-up than before! But this time, there's no time-limit!

—Majin Boo to Gokū, A One Time Only Miracle… Will the Super Combination of Gokū and That Person Succeed?


Majin Boo with Gohan, Piccolo, Goten, and Trunks absorbed.

This form is the final, and strongest form, of the Majin Boo seen in the series. After absorbing Gohan, Majin Boo progressed from his Piccolo absorbed state into this state, where he used Gohan's Potental Unleashed power as his primary power source. There are only a few minor physical differences; in this state, his antennae stretches down past his back, being at its longest yet seen, and he now wears Gohan's orange-and-blue gi top.

His personality has received another slight change, becoming more boastful than previous — traits likely inherited from the very confident Gohan. He belittles both Gokū and Vegeta, jokingly giving the former five seconds to find a partner to merge with. In the English dub, Boo even mockingly calls Gokū "Dad" shortly after absorbing Gohan; merely rubbing salt in the wound over the loss of his eldest child.

It is the power increase in this state that is the most drastic difference. By using Gohan as his primary source, Majin Boo has become, by his own admission, stronger than he's ever been. His strength outclasses that of Son Gokū and Vegeta, the former resorting to fusing with the latter to gain any advantage. In the anime, Majin Boo battles Gokū and Vegeta in this form and beats them handily. However, when Gokū and Vegeta formed Vegetto, the Djinn was outclassed in every respect. He still showcases the ability to use techniques from his captured victims, even those who have unfused; he utilized the Super Ghost Kamikaze Attack against Vegetto, and in the anime, was able to channel the Masenkō and the Kamehameha through the Ghosts.

Lookout Majin buu

Majin Boo has found the source of power on Earth.

Majin Boo finally finds the source of power that peaked his interests and confronts the Dragon Team. Majin Boo smiles at the sight of finding new targets he quickly changes his demeanor. This frightens even the likes of Piccolo who tries to interact with Majin Boo.[18] Majin Boo begins to look around, after his brief search he makes a simple demand to Piccolo. Piccolo confused at his request asks hims to clarify his request, angering Majin Boo and screams volatility, demanding the same request.[19] The burst of anger terrifies the Dragon Team with the strength of his voice. Due to the obscure nature his request was this causes confusion between the two, causing Piccolo to ask him again on exactly what is he searching for. The question poses Majin Boo changes his demeanor once again to a frightening grin. Majin Boo clarifies his demands to be brought the opponent he was promised previous by Son Gokū. Majin Boo explains that there is two powers that brought him to the Castle of God. Confirming to Kulilin and Yamcha that he can in fact, sense ki.[20]

Piccolo Buu Negociation

Piccolo attempts to negotiate with Majin Boo.

Piccolo becomes uncomfortable at such a request and confesses that in fact the two powers in the Castle of God, but informs Majin Boo that they are resting to prepare for their battle, to the disappointment of Majin Boo. Majin Boo disregards their rest, demanding Piccolo to wake them up to the annoyance of Majin Boo. Majin Boo informs Piccolo that he's chosen to fight them now. Piccolo tries to plea with Boo and offers that he should wait until they’re in top performance. And tries goad his interests of fighting the strongest opponent, to no interest to Majin Boo. Majin Boo then begins with stretching his body to prepare and notes that he has no interest in such notion because of his impatient nature. Now in a critical juncture Piccolo is forced to goad Boo's rampage to buy some time. Piccolo goads Majin Boo offers him to kill every single person on Earth.[21]


Majin Boo nearly eliminates the entirety of mankind.

Majin Boo is enticed at such a bargain. The monster then begins to walk around the circumference of the Castle and continues to circle the area to the confusion of the Dragon Team, Majin Boo scours out the entirety of the global population in order to now the exact number of people are still left on the planet, unbeknownst to the Dragon Team.[22] Majin Boo completes his reconnaissance of the global population and then returns to confront Piccolo. Majin Boo lifts his arm with a mischievous smile, even enough to make Piccolo flinch.[23] Majin Boo then releases a massive amount ki from his body enough to encircle his own body and releases above the world, scaring the entirety of the remaining Dragon Team, as they are each illuminated by the blast itself. The attack releases a powerful technique to eliminate the entirety of the population. The ki missles each are guided to specifically target the population of Earth to the surprise of Dende and Piccolo.[24]

Majin Boo then informs Piccolo that all Earthlings are now dead and orders him to bring out the young saiyans out. Piccolo knowing he has exhausted all of his time to bide, accepts Majin Boo's terms. Piccolo informs them that they are asleep and to give them at least an hour to get ready. Majin Boo responds to Piccolo and asks him the amount of time an hour is.[25]

Piccolo uses Materialization Sorcery to create an hourglass to the eagerness of Boo. Piccolo tells Boo that he’ll know when the hour passed when the entirety of the sand hits the bottom quickly angering Majin Boo dejecting out of his impatience with a resounding, no. Piccolo tells him that Mr. Satan’s daughter wants him to wait. Piccolo tries to stall Boo by using the bond between Mr. Satan and the Majin Boo he’s had of. In anger Boo decides to agree to the terms to wait for the hour. Majin Boo tells Piccolo that he’ll wait momentarily then he’ll kill everyone even Videl. Boo then begins to stare at the hourglass to run out.[26]

Some time passes by as Majin Boo continues to watch the hourglass. He is then confronted by Chi-Chi who is angered over the loss of Gohan who died at his hands. Chi-Chi slaps him to no avail. Majin Boo shifts his attention towards Chi-Chi and commands his her to transform into an egg to her confusion-releasing his Transfiguration Beam to turn her into an egg. Majin Boo then proceeds to killing her by squashing her in her egg form and returns to wait for the hourglass to finish.[27] Majin Boo shortly after reaches his breaking point. Majin Boo screams out that he no longer plans to wait, destroying the hour glass with his arm.[28]

Majin Boo becomes discontent, but Piccolo tries to console Majin Boo and tries to calmly explain that he has reached the half-way point. Majin Boo shoots a ki wave from his fingertips towards Piccolo. The blast is strong enough to not only destroy chunk of God's castle, luckily the wave missed Piccolo. Boo rejects his plea and orders him that he will now fight. Just then, in a burst of anger Majin Boo orders him to bring out his opponent. Piccolo at a conclusions asks Majin Boo to follow him.[29] Piccolo tells him to follow him to his opponent. Majin Boo follows Piccolo into the Castle of God to meet Goten and Trunks in the Room of Spirit and Time.[30]

The two continue to explore the castle and Majin Boo becomes impatient and asks Piccolo how further the area is, as Piccolo asks him to have patience.[31] The closer they reach to the Room of Space and Time Piccolo offers him food. Majin Boo refuses his offer threatening Piccolo that he'll kill him if he continues to stall. Piccolo announces their arrival to the joy of Majin Boo.[32] Majin Boo enters without any difficulty or added stress and comments on the peculiar location he's entered. Majin Boo then directs his attention towards the two Saiyans and becomes disappointed.[33]

Trunks and Goten begin to start their 'performance' and use theatrics to anger Majin Boo. As the two boys begin their Fusion Majin Boo goes on the attack and punches Trunks in the face. Afterwards Majin Boo is reprimanded by Trunks for attacking him before he could finish his antics. Trunks continues by denigrating Majin Boo and demands for his patience to the disappointment of Majin Boo.[34] After both Goten and Trunks perform Fusion to turn into Gotenks, Majin Boo remembers them from their previous encounter.[35]

Majin Boo is attacked by a barrage of Gotenks punches and hard strikes, and after the ineffective blows connect on Majin Boo he utters a single response, asking if he too could begin his attack.[36] Majin Boo stands idle as Gotenks taunts him to the discontent of Majin Boo. Gotenks then prepares his second assault introducing his new attacks; Dynamite Kick, Rolling Thunder Punch to the abdomen, Boar Attack, Power Tackle, Miracle Super Punch, Magnum Sunday, Ultra Missile Parfait, Hyper Plasma Short Cake, each ineffective against Majin Boo.[37] Majin Boo finally responds with a slap to the face and knocks down the young super warrior to ground.[38]

Majin Boo begins to get bored and frustrated with Gotenks. Gotenks energized by his insulting remarks turns into a Super Saiyan to the surprise of Majin Boo.[39]

Creation and Conception[]


  • Majin Boo's name is a pun on the magic phrase from the movie Cinderella, "Bibbidi Bobbidi Boo". The wizards Bibidi and Babidi all derive their names from different portions of this phrase.[40]
  • While the term Majin is used to describe both Lucifer and Majin Boo (all forms), they are written differently and have different meanings, the former being demon-god (魔神) and the later demon-human (魔人).

  • (to Gohan) "I mean I've been expecting you. Ever since I started fighting those little brats. Even while I was fighting, I could sense your power in a far away place. I could feel it growing. I knew you would be coming here. Opposites attract one another. Yes. Yes. I've been waiting for you the whole time. I can't let a power greater than mine exist."
  • (to Gohan) "I'm not interested in fairness. I'm interested in the extinction of every living creature on this planet! A good fighter knows his mental and physical limitations. But a great fighter will figure a way around them."
  • (to Gohan) "You're not paying attention to my moves. Piccolo taught you better than this. Didn't he?"
  • (to Gohan) "Could have been your head. And with all that training on the cliffs."
  • (to Gohan) "I possess the greatest powers in the Universe! And I'll use them all to kill you!"
  • (to Gohan) "There must be something you're still anxious to prove, Gohan. How amusing. The whole world is depending on you! You're the savior. And you're three breaths away from the end."
  • (to Gohan) "Stop me if you've heard this one before. One final move and game over! Kamehameha!"
  • (to Gokū) "Oh, don't take it too personally, Goku. Everybody fails. Your failure just means the end of the world"
  • (to Gohan) "What's the matter? Weren't you going to kill me? You've got to watch your opponents movements more closely. You were taught that in training, right? By Piccolo?"
