Background / History

In ancient times, Buu killed North Supreme Kai and West Supreme Kai and absorbed South Supreme Kai, the strongest of the five Supreme Kais. Supreme Kai recognizes Buu’s briefly muscular form during his later regression as the form associated with South Supreme Kai’s absorption 46.

Buu also absorbed the Grand King Kai. Goten identifies this absorbed deity’s kindness as the reason Fat Buu can be approached through reassurance and treats rather than violence 29.

Babidi seeks to revive Buu by collecting energy from Earth’s fighters. The stolen energy delivered by Yamu and Spopovich fills roughly half of Buu’s egg, while Babidi’s spaceship battles are arranged to gather more energy through injuries inflicted on the intruders 20 21 22 23.

Appearance

Buu’s appearance changes substantially through separation, absorption, and regression.

• Fat Buu: A portly, pink figure with small, squinting eyes and a constant smile. He wears a short black vest, white trousers, yellow gloves, a pinkish-purple cape, and a belt bearing an “M” buckle. A tentacle-like appendage and small vents mark his head 29.
• Thin Buu: Extremely thin, with dark skin, black sclera, and a wicked smile 30.
• Super Buu: More proportionate and nearly human-shaped, with a bare torso, no nose, no cape or gloves, and hands whose four fingers appear fused together 31.
• Vegeta-Buu: Develops more defined facial features, five-fingered hands, and a head appendage extending to his hips. Wears a blue, tight-fitting vest matching Vegeta’s 34.
• Kid Buu: A petite figure standing less than one and a half meters tall 46.
• Janembuu: Retains Buu’s head antenna while gaining Janemba’s sword-like helmet protrusions, dark pink armor-like covering, and a deep pink tail. Speaks with a combined, dual-layered voice 48 50.

Personality

Fat Buu is childlike, food-driven, and receptive to kindness. On awakening, he asks for chocolate rather than immediately attacking. Goten successfully draws him away from Babidi with candy, despite the sorcerer’s threats to seal him again 29.

Thin Buu embodies a more concentrated evil, while Super Buu combines malicious confidence with enough intelligence to exploit absorption. He initially dismisses the Saiyans, ignores Supreme Kai as beneath his notice, and becomes irritated by the fighters’ insistence on deciding their duels through rock-paper-scissors 30 31 32.

Buu’s confidence collapses against Super Saiyan 4 Goten. He reacts furiously to mockery, attempts covert absorption, and invokes Vegeta’s captivity to discourage Goten from killing him. Although capable of deception, he celebrates Goten’s apparent absorption without recognizing that neither his appearance nor his power has changed 39 40 42 44 45.

Kid Buu acts with little communication, immediately resorting to destructive attacks. He nevertheless shows fear toward Goten, and his opportunistic absorption of Janemba demonstrates that his instinct to acquire stronger victims remains intact 46 48.

Abilities & Skills

Regeneration and Body Manipulation

Buu’s body behaves like malleable clay or slime, allowing him to recover from severe damage and separate portions of himself 33 42.

• Restores a large hole in his abdomen and other injuries almost instantly after Vegeta’s Big Bang Attack; his ki does not diminish during the apparent damage 33.
• Survives Vegeta’s Final Flash despite the apparent disappearance of his body and detectable ki 34.
• Detaches a small blob from his leg and sends it underground for a concealed absorption attempt 42.
• Regeneration does not save Janembuu from Goten’s final Kamehameha clash 50.

Absorption

Buu envelops targets with his liquid body and incorporates them into himself. Successful absorption can change his appearance and grant power, techniques, and memories 31 34 35.

• Thin Buu absorbs Fat Buu to become Super Buu 31.
• Acquires Vegeta’s combat abilities and accesses his memories, including knowledge of the Great Ape transformation and the Dragon Balls 34 36 44.
• Captures Goten physically, but gains no power or visible transformation because Goten enters with a protective barrier 44 45.
• Absorbed individuals remain accessible inside his body; Goten locates Vegeta and Fat Buu there 45.
• Disconnecting Fat Buu destabilizes Buu’s identity and triggers his regression into Kid Buu 46.
• Kid Buu envelops Janemba to produce Janembuu 48.

Physical Combat and Energy Attacks

Buu combines high-speed close combat with destructive energy blasts.

• Dodges and kicks away Super Saiyan 2 Vegeta, then withstands attacks from Trunks and Gohan after absorbing Vegeta 32 35.
• Exchanges repeated airborne blows with Super Saiyan 3 Goku 35 36.
• Fires compact purple energy spheres and creates a much larger sphere capable of destroying Earth 33 40.
• Kid Buu’s redirected energy sphere destroys the moon created by Supreme Kai 46.
• Vegeta-Buu and Kid Buu are both decisively outmatched by Super Saiyan 4 Goten 39 40 46.

Janembuu’s Acquired Techniques

Through Janemba’s accumulated villain powers, Janembuu gains techniques associated with Frieza and Cell 48 49 50.

• Energy barrier: Withstands Goten’s barrage inside a purple barrier recognized as Perfect Cell’s technique 49.
• Pursuing energy discs: Launches two cutting discs associated with Frieza; Goten ultimately shatters them with energy-reinforced fists 50.
• Piercing energy beam: Uses Frieza’s fast, highly penetrating beam, which Goten dodges 50.
• Kamehameha: Uses Cell’s version of the technique in the final beam struggle against Goten 50.

Relationships

• Babidi — Would-be master and reviver. His commands and threats fail to secure Fat Buu’s obedience once Goten offers candy 29.
• Son Goten — Initially befriends Fat Buu, then becomes the evil Buu’s principal opponent. Infiltrates Buu to rescue Vegeta and Fat Buu, and ultimately destroys Janembuu 29 44 45 46 50.
• Vegeta — Opponent and absorption victim. Buu takes his strength, techniques, and memories before Goten removes him 33 34 45 46.
• Son Goku — Battles Vegeta-Buu as a Super Saiyan 3, but cannot establish a decisive victory before Goten’s transformation changes the battle 35 36.
• Supreme Kai — An ancient survivor who fears Buu and recognizes the significance of his changing forms 30 31 46.
• Janemba — Absorbed by Kid Buu; their merger creates Janembuu and elevates the threat to Super Saiyan 4 level 48.

Story Role / Major Arcs

Early Awakening and Separation

Goten blasts Buu’s egg to force an early awakening, then uses sweets to draw Fat Buu away from Babidi. This peaceful solution fails when Buu unexpectedly suffers, emits dark purple gas, and separates into Fat Buu and Thin Buu. Goten and Trunks cannot prevent Thin Buu from absorbing his counterpart and becoming Super Buu 29 30 31.

Absorption of Vegeta

The Saiyans choose individual duels instead of coordinated combat. Vegeta initially struggles, then gains enough power to overpower Buu and seemingly destroy him with Final Flash. Buu survives and absorbs him, forcing Goku to use Super Saiyan 3 while Goten pursues his own transformation 32 33 34 35 36.

Defeat by Super Saiyan 4 and Internal Rescue

Super Saiyan 4 Goten overwhelms Vegeta-Buu, redirects his planet-destroying attack, and frustrates his attempts at retaliation. Buu eventually envelops Goten, believing he has won, but Goten deliberately enters with protection to rescue the captives inside. Removing Vegeta and disconnecting Fat Buu leads to Kid Buu’s emergence 39 40 42 44 45 46.

Janembuu and Destruction

Goten is preparing to finish Kid Buu when Janemba arrives from a black void. Kid Buu absorbs Janemba during the ensuing battle, creating an opponent comparable to Goten. Their clash shakes Earth and destabilizes the surrounding space. Goten wins the final Kamehameha struggle and annihilates Janembuu, but the world’s barrier breaks and pulls Goten into collapsing space 47 48 49 50.

Trivia

• Super Buu reads manga while the Saiyans argue over who will fight him first, then calmly puts it away when Vegeta prepares for the duel 32.
• Goten notices that Buu’s separation occurs without the extreme anger he expected from his knowledge of the original story 30.
