Personality
Majin Buu has very evil yet child-like mentality and yearns only for destruction. He also has a large appetite, which he sates by transforming other beings into food and eating them. When faced with powerful opponents, he takes great pleasure in battling them and ultimately defeating them. Similarly, he greatly enjoys absorbing other beings as he increases his own power.

Motive
Majin Buu generally absorbs people to ensure victory when he is in a losing battle. By absorbing them he simultaneously eliminates an opponent and greatly increases his strength.

History
Millions of years prior to the events of the Dragon Ball series, Majin Buu was created by the evil wizard Bibidi and spread destruction throughout the universe. During his destruction, he battled the Supreme Kais (or Kaio-shins); god-like entities who protect the universe.

Dragon Ball Z, Episode 277
After battling and defeating the South Supreme Kai, Buu absorbed him, gaining a larger more muscular form. He then battled and absorbed the Grand Supreme Kai, gaining his "Fat Buu" form.

Some time afterwards, Bibidi seals Buu in a ball due to his disobedient behavior. The sealed Buu is sent to Earth, but the East Supreme Kai kills Bibidi before he can release Buu again.

Millions of years later, Bibidi's son Babidi goes to Earth releases Buu once again, thus initiating the events of the Majin Buu arc. Buu begins to rampage across Earth and eventually kills Babidi. However, Buu later befriends Mr. Satan and grows to care for a puppy named Bee. After Bee and Mr. Satan are nearly killed by two gunmen, Buu becomes furious and splits into his good and evil halves.

Dragon Ball, Chapter 485, Dragon Ball Z, Episode 255
The two halve of Buu battle it out, but Buu's evil half wins. The evil "Thin Buu" turns the good "Fat Buu" into chocolate and eats him, absorbing him into his body. This results in "Thin Buu" changing into the muscular "Super Buu".

Buu later battles with Gotenks (the fusion of the half-Saiyans Goten and Trunks) and then, after Goten and Trunks defuse, battles the half-Saiyan Gohan who completely outmatches him.

Dragon Ball, Chapter 499, Dragon Ball Z, Episode 265
Knowing he cannot defeat Gohan, Buu goads Goten and Trunks into fusing again. However, it turns out to be a trap as Buu had broken off parts of himself to sneak up on and absorb Gotenks as well as the Namekian Piccolo. The two are absorbed into Buu's body and he changes into his Gotenks form.

Buu then battles Gohan and quickly gains the upper hand. Soon after, the newly-revived Saiyan Goku arrives attempting to fuse with Gohan.

Dragon Ball, Chapter 502, Dragon Ball Z, Episode 267
Whilst Gohan and Goku are attempting to fuse, Buu reverts from his Gotenks form to his Piccolo form, since Gotenks' fusion was only temporary, and loses a great amount of power. However, using another part of him that had broken off, Buu uses it to sneak up on and capture Gohan, absorbing him as well. This results in him transforming into his Gohan form and becoming substantially more powerful.

The Saiyan warrior Vegeta then arrives and fuses with Goku, resulting in the fused warrior Vegito. Vegito easily outclasses him and Buu attempts to absorb him as well.

Dragon Ball, Chapter 505, Dragon Ball Z, Episode 272
Buu manages to cover Vegito and pull him into his body like the others, but Vegito actually intended Buu to absorb him and put up an energy field so he wouldn't be absorbed like the others. After being sucked into Buu's body, Vegito defuses back into Goku and Vegeta who search Buu's body for their absorbed comrades. They find them in Buu's head, trapped in spherical cocoons, and free them from Buu's body. They also find the absorbed "Fat Buu" and break him loose from his cocoon, but do not take him out of Buu's body.

Later, when Goku and Vegeta battle the resulting "Kid Buu", "Fat Buu" manages to escape Buu's body as well. Goku then conjures a giant Spirit Bomb and destroys Majin Buu once and for all.

Method of Consumption
Majin Buu is able to break off parts of himself that are capable of independent movement separate from his main body. Using these segregated parts, which have a gooey consistency, he can engulf his victims as they stretch out and cover his victims' bodies. Once his victims are completely engulfed, the body parts fly back towards Majin Buu and they and the victims inside merge with his body. It is unknown precisely what the range is for Buu controlling the pieces of him he breaks, but they can evidently be controlled from at least several yards away. Once a victim is engulfed, escape is extremely difficult if not outright impossible. After absorbing his victims (who are shrunken and cocooned inside his head), he inherits many of their traits, including power, abilities, physical appearance (including clothes), intelligence, and even personality. When absorbing multiple people, Buu's appearance changes mainly to reflect the strongest person he has absorbed. This is demonstrated when, after absorbing Gotenks and Piccolo, Buu's appearance initially becomes similar to Gotenks, but after Gotenks's fusion wears off his appearance changes to that of Piccolo's.

However, as seen in Dragon Ball GT, Buu's absorption ability can be used in a beneficial way as seen when "Fat Buu" took Pan and Mr. Satan into his body to keep them safe. In this instance, while Pan and Mr. Satan were still confined to cocoons within him, they remained conscious and Buu did not siphon their energy or take on their appearance or abilities.

Appetite
In terms of absorption, Buu does not consume people to sate his hunger, but rather to become stronger and defeat his opponents. To this end, he will absorb as many people as he feels necessary to ensure victory. There is no apparent limit to how many people he can absorb, but he was able to consume Goten, Trunks, Piccolo, Gohan, Goku, and Vegeta without difficulty.

Status of Swallowed Prey
Buu's victims are shrunken down and encased in cocoons inside his head where he draws power from them. People absorbed in this way are rendered unconscious and presumably can do nothing to effect an escape. In Goku and Vegeta's case, although they were shrunken down into Buu's body, they were able to shield themselves from the absorption process and had free reign to explore his body. Presumably, overtime, Buu's victims are eventually completely dissolved and integrated into his body as there was no trace of the South Supreme Kai or Grand Supreme Kai (both of whom had been absorbed by Buu millions of years prior to the events of the Majin Buu arc) when Goku and Vegeta explored his body. Additionally, as explained above, though still confined to cocoons, people that Buu absorbs may remain conscious and suffer no ill effects of the absorption if he so chooses.
