Unknown, unfathomable power – Buu possess an odd ki signature that makes it hard to tell how strong Buu really is. Whether Buu's power level is incredible, or not that much is unknown even by Majin Buu.
Absorption – Majin Buu fully engulfs and takes an opponent into his body to cause an increase in physical and mental prowess. Majin Buu usually has a severed body part liquefy, or he has a piece of skin fall off of his body. The goo will then sneak up behind the person, and stretch itself to be large enough to accommodate the target. The goo will then leap onto the person. The goo will try to smother as much of the target as it can on the first strike to make the capture easier. If Majin Buu is lucky, the goo will completely cover the target on the first leap. Once the goo is on the person, it will quickly cover up any part of the person that was not covered during when it first leaped. Once the target is completely covered, the goo will squeeze and solidify, trapping the person. It is seemingly impossible for anyone to escape the goo, no matter what the circumstances (such as Piccolo who the goo took a long time to cover due to his armor, Gotenks' constant struggle with the goo, and Gohan who was physically stronger than Buu at the time). Majin Buu will then raise his finger up, and the goo will then launch up into the air with the person inside of it. The goo will then fly straight into Majin Buu and cover him. During the transformation, Majin Buu will become liquid himself, meaning that he is basically taking over the goo and has surrounded the person with his own liquefied body. He then begins to meld back into solid form, making sure the person is in the center of the goo. The person is shrunken and is put inside Majin Buu's head in a pod. The transformation is long and usually accompanied by loud moans and groans, most prominently heard when Super Buu absorbs Gotenks and Piccolo. As Buu is absorbing those two, the Fusion vest is seen forming roughly on Buu's shoulder, showing that Majin Buu is using Gotenks as his main power source, and whether these sounds are of Buu struggling to absorb two beings at once or just because of all the power that Gotenks has in his mighty Super Saiyan 3 transformation or that Gotenks is still struggling during the absorption. When absorbing another being, Majin Buu always takes qualities of their outward appearance as well. He also gains knowledge of their attacks, like Piccolo's Special Beam Cannon (used in the anime and in video games), Gotenks' Galactic Donut and Super Ghost Kamikaze Attack, and the Kamehameha. Oddly enough, even when Buu's head is injured, the people pods his absorbed victims are in seem to be unfazed somehow, as Vegito and Gotenks blew up Super Buu numerous times, and when Vegito was "absorbed" and rescued the others, they were all in one piece. This also happens with the fat Majin Buu form of himself being intact though Buu's head (and body) have been reduced to pieces or even smoke at one point, even after this fat Buu was detached from his absorption pod shortly before Super Buu was reduced to his original, smaller Kid Buu form, in which he was blown up numerous times by both Goku and Vegeta.
Shrinking - When Super Buu absorbs someone, he shrinks them down to tiny sizes so they fit inside his body.
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 from Goku's Spirit Bomb since it destroyed every atom of Buu. His unrivaled regeneration plus his endless resilience and stamina granted him near-immortality; he is shown at one point to survive the explosion that destroys the Earth when he blasts it into nothingness. However, it is shown during the fight between Vegito and Super Buu that even his regeneration has its limits; after repeatedly being blown to bits and pounded into oblivion by Vegito, 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. It is also stated that Buu cannot regenerate if he is completely disintegrated. Named Rebirth in the Budokai Tenkaichi video game series.
Uniqur interior body - Super Buu's body contains Blood Cells that will attack intruders, along with Blisters that creates Enzymes. In filler Super Buu can also create clones of those he has absorbed to fight intruders to his body - the Fake Z Fighters being the only ones displayed. Super Buu can also create a miniature version of himself inside his body to fave intruders, this miniature version is called Super Buu (Clone).
Human Extinction Attack – Super Buu fires a massive amount of energy waves from his left palm that disperses to seek out and kill all human beings. Only those with a high-enough level to evade their path escaped from death, with Mr. Satan spared due to the fat Majin Buu's influence. This Energy Blast Barrage technique is also known as Genocide Blast and Assault Rain.
Ultra Assault Rain (超アサルトレイン) - A enhanced version of Super Buu in his Giant Form used in Dragon Ball Heroes.
Antenna Beam – He launches a small, bluish-green bolt of energy from his antenna. Super Buu (w/ Gotenks absorbed) uses this attack on Gohan while he is lying in a crater. He also uses an enormous version fired in the same stance used to fire the Genocide Blast, after falling victim to Gotenks' volleyball technique.
Chocolate Beam – Majin Buu's unique ability to change objects and living beings around him into inanimate objects such as sweets and milk (a process only reversible by himself). Though he usually turns them into foods, Majin Buu has transformed a small population into clay for his house on one occasion during the Majin Buu Saga, and Super Buu once transformed a rock into a toilet when the Saiyans invaded his stomach in the anime. Vegito is the only entity that is shown to be able to retain his will or move after being hit by the attack, fighting Super Buu as "the world's strongest coffee candy". Named in the Budokai Tenkaichi series.
Crazed Elbow Hit – The dashing elbow strike he used to attack Trunks when Buu first entered the Hyperbolic Time Chamber. Named in the Butōden series.
Mystic Ball Attack – Also used by Kid Buu, Super Buu used it in the battle against Gotenks and later on when battling Super Saiyan 3 Goku on the Kai Planet, Super Buu contorts his body vertically into a ball before launching himself at his opponent at great speed. The attack was used by all of Super Buu's forms (that engaged in battle) and Kid Buu. Kid Buu used a special version in which he detaches his arm and rolls it into a Ball. The attack is called Ill Ball Attack in the Budokai series.
Vice Shout – Super Buu lets out all of his energy in a high pitched scream, ripping dimensions. It is said to possess enough power to destroy the whole universe and has a barrier to protect himself. First used to escape the Hyperbolic Time Chamber and later used as a last resort against Vegito. In Dragon Ball: Xenoverse, it is called Dimension Cannon and appears as Super Buu's Evasive Skill.
Shout! - Super Buu's signature attack in the Raging Blast Series.
Wrap Attack – Due to Super Buu's ability to stretch very far, Super Buu can often detain a person by stretching and wrapping his body around them. He can do this with any part of his body, but most often he will usually do this by stretching the area from his chest to his feet around the target very quickly, then constricting before the person can react. Super Buu can also regenerate his body around a person in order for a surprise attack. If the target is particularly strong, Super Buu can stretch and wrap every inch of his body around the target. Super Buu can use this attack to his advantage in various ways. He will usually just keep the target wrapped up in his body and squeeze the target, hurting them. He will only let go if the person is strong enough to break free (which no one could do but Vegito, due to Super Buu's very strong constriction). If the target is not strong enough, they are at the mercy of Super Buu, and Super Buu will keep them wrapped up to squeeze until the target is dead or he decides to let go himself. Super Buu can also use this attack for other advantages, such as flying at high speeds with Gotenks wrapped up in his torso, then suddenly stopping and releasing Gotenks, sending him flying into the ground.
Bring It! – A counter rush attack that Super Buu used after his absorption of Gotenks and Piccolo. First used during his fight with Ultimate Gohan, and named in the Raging Blast games.
Vanishing Beam – A technique used many times by Super Buu and is his signature technique. It is usually an average-sized, pink or purple beam fired from the palm. He uses it many times in his battle with Gohan. He also uses an enormous version fired in the same stance used to fire the Genocide Blast, the Super Vanishing Beam, after falling victim to Gotenks' volleyball technique. The name comes from the Budokai series.
Finger Beam – A powerful energy wave shot from the finger. Super Buu's version looks like his Vanishing Beam technique. He uses this attack on Gotenks right when the latter splits back into Goten and Trunks due to the fusion time having run out.
Destroy Everything! – A massive pink energy sphere that has enough power to destroy a planet, similar to Kid Buu's Planet Burst. Super Buu w/ Gotenks attempts the attack against Gohan and Tien, but he is stopped by Goku cutting him in half with a Destructo Disk. Super Buu w/ Gohan uses the attack during his battle against Vegito, but the latter manages to kick it up into space. This is one of Super Buu's Super Attacks in the Raging Blast games in his "Gotenks absorbed" and "Gohan absorbed" states.
Kamehameha – A powerful energy wave attack. Also used in the Budokai series.
Super Kamehameha – The upgraded version of the Kamehameha used by Buu (w/ Gotenks absorbed) in his battle with Ultimate Gohan. Also used in the Budokai Tenkaichi series.
Galactic Donut Volley – Super Buu can use Gotenks' Galactic Donut technique after absorbing him, and he usually fires a series of three energy rings. Named in the Budokai Tenkaichi series.
Mystic Shooter – Super Buu launches a great number of red energy disks that slice through any inferior object or projectile, used by Super Buu (w/ Gohan absorbed) against Goku and Vegeta. Named in the Raging Blast games.
Ultimate Cannon – A pink energy sphere attack twice, both times to attack Goku and Vegeta right before they fuse into Vegito. Named in Dragon Ball Z: Battle of Z, and called Static Orb in the Dragon Ball Z Collectible Card Game.
Staggering Super Slap – A surprise attack used against Goku and Vegeta during the battle inside himself. Named in the Dragon Ball Z Collectible Card Game.
Cross Slash – An energy attack in the shape of a red X used by Super Buu w/ Gohan absorbed. Named in the Dragon Ball Z Collectible Card Game.
You'll Die a Painful Death! – A rush attack used by Super Buu w/ Gohan absorbed during absorbed in his fight with Super Vegito. Named in the Raging Blast games.
Super Ghost Buu Attack – Super Buu uses Gotenks' Super Ghost Kamikaze Attack, performing the same maneuvers, except resembling Super Buu in appearance rather than Gotenks due to the ghosts being duplicates of the attack's user. These ghosts are also different from those generated by Gotenks, since they can perform the Kamehameha and Masenko attacks.
Eye Lasers – Super Buu fires two beams from his eyes. Buu (w/ Gotenks absorbed) used it against Ultimate Gohan to bring him out of hiding. Buu also used eye lasers to destroy some buildings in an empty city after he thought he killed Vegito.
Dangerous Liquid Bomb – Super Buu shoots out of his solid form and liquefies himself so as to force his ooze into the opponent orally. He uses this technique twice, once on the accomplice of the gunman who shot Bee, Smitty. On this occasion Super Buu engorged the man, causing his body to expand to the point it could no longer take as he exploded soon after. He uses it once again on Vegito, this time in a surprise attempt to take control of his body rather than to over-engorge him as he did with Smitty. The effects were seen through Vegito's hyper muscle growth, as Super Buu seemingly became an addition to Vegito's muscle mass. If Vegito powers up, Super Buu gets stronger, due to now being part of Vegito. Vegito quickly realizes a way to dispel Super Buu from his body, however. By manipulating his ki, Vegito managed to trap him, and literally beat Super Buu as he popped up on varies points on his own body as a large lump. Eventually, Super Buu made his way to Vegito's back, where the Saiyan then slammed himself backwards against the ground. This caused Super Buu to shoot back out of Vegito's mouth the same way he came in, leaving himself very exhausted from the failed takeover.
