Despite his immense power, Super Buu can increase his power even further by using his absorption ability, which can be performed by either turning his victim into food before eating them or he can separate a piece of himself and absorb the victim by engulfing them in a gooey mass that can adjust its size. With each absorption, Super Buu's physical appearance always changes, including taking on exact replicas of his absorbed victims clothing, as well as facial/body features and other characteristics such as intelligence and signature techniques. In the Budokai Tenkaichi video game series, his absorbed forms are simply written as Super Buu next to a bracket containing the victim's name.
Backround EditSuper Buu was formed when Evil Buu ate Majin Buu, who was turned into chocolate by his own Chocolate Beam and transformed (the transformation was mostly hidden behind pink smoke). He brutally killed Smitty (one of the deranged gunmen responsible for his creation) by oozing into him through his mouth as part of his Dangerous Liquid Bomb technique and expanding until Smitty burst, though the influence of the Fat Buu prevented him from killing Mr. Satan and Bee. His intelligence in this form (before absorbing Piccolo) is quite bizarre. When Piccolo begged him to wait an hour for Gotenks to prepare for the fight, he didn't know what an hour was, but when Piccolo conjured an hourglass to show him how long it was, he was apparently capable of counting all the particles of sand and deducing the length of the hour in a matter of seconds. Also, he seemed able to count the number of civilians left on the entire planet after just one trip around the circumference of Kami's lookout.
Now with the ability to sense energy, he made his way to Kami's Lookout where the z fighters and many of their friends and family were taking refuge. He demanded to see the strong warrior that Goku told his previous counterpart about and when Piccolo, in a desperate attempt to distract him, told him that he could amuse himself by terrorizing the people of Earth (knowing they could be revived with the Dragon Balls), Super Buu instead did a Human Extinction Attack, eliminating the entire population of Earth except Mr. Satan, Bee, Tien Shinhan, Chiaotzu, Korin, Yajirobe, and those already present at the Lookout (Piccolo, Bulma, Chi-Chi, Videl, Yamcha, Krillin, Android 18, Marron, Master Roshi, Ox-King, Trunks, Goten, Dende, Mr. Popo, Oolong and Puar).Piccolo eventually agreed to take him to Trunks and Goten, but told him to wait an hour. It wasn't until he found out Videl was Mr. Satan's daughter that he accepted, saying her smell was similar to Satan's. However, Chi-Chi slapped him for killing Gohan, and he responded by turning her into an egg and crushing her. Later, he grew tired of waiting and smashed the hourglass, so Piccolo led him to the Hyperbolic Time Chamber to fight Gotenks in there, knowing that if Gotenks lost, he could destroy the entrance and trap Buu (and himself along with Gotenks) inside for eternity. Piccolo deliberately took the longest possible way to the chamber in order to stall him and to give Goten and Trunks more time to prepare (which Buu immediately caught on to and soon warned Piccolo he'd kill him for doing so if he tries it again). When they entered, it proved wrong the myth that only two can enter at a time. Goten and Trunks fused into Gotenks and fought Super Buu. During the fight, Gotenks punched Buu in the chin, and following this Buu's eyes were red (as opposed to white, his original color in the anime) and his tongue green (as opposed to red), possibly to match the manga's volume 41 cover, which depicts him with red eyes (he is never seen changing colors in the manga, as the kick scene was filler). Soon, Gotenks turned Super Saiyan, and when his Galactic Donut attack did nothing as usual, he uses his Super Ghost Kamikaze Attack to created a miniature ghost version of himself. Not knowing of the attack's true purpose, Buu assaulted the ghost, which explodes on contact. He is only disrupted by this to a small extent (and while Gotenks made 10 more, he becomes bored and reads a magazine and drinks a soda), but figures a way to best this trick by simply moving out of the way, causing 2 of Gotenks' 10 newly created ghosts to simply destroy each other, while for comedy value, two more ghosts give each other a handshake and explode. When the first two ghosts to actually attack are gone, Gotenks devises a plan to lure Buu into it.
