Dämon Boo Dämon Boo is the evil creation of Babidi. He  is perhaps the most interesting of all villains in Dragon Ball Z.  Not only is he the most powerful and indestructable villain, but his  personalities also seemed boundless. Boo is capable of  absorbing his enemies and their powers as well. He absorbs his  enemies in two ways. The first way is transforming the target into a  palatable item (such as chocolate - Boo's favorite) by his  "antenna." The second method is by wrapping the target using a part  of himself as a blanket and pulling the victim into his body. Every  time he absorbs an enemy, his appearance will also mutate,  resembling the look of that enemy. Boo first showed himself  as fat and goofy-looking. The reason why Boo looks fat and goofy is  because he had previously engulfed a kaiwongshin with such  figure. Boo's encounter with Mr. Satan was the most  interesting. Mr. Satan revealed the "good" side of  Boo which we  never thought Buu had. Mr. Satan even convinced Boo never to commit  any evil deeds again. Unfortunately, the "evil" in him cannot be  contained. The "evil" was unleashed when Boo was angered by the near  fatal shooting of Mr. Satan. The "evil" Boo splits from the "good"  Boo. The "evil" Boo easily defeated and re-absorbed the "good" Boo  demonstrating that there is really more "evil" than "good" in Boo.  The absorbtion transformed Boo into a purely evil entity. We  do not see the "original" appearance until the combined Vegeto  infiltrated the body of  Boo and plucked out everyone he has  absorbed, including "good" Boo, also dramatically reducing his  power. Nevertheless, he still has enough power to destroy earth, and  does so. The final battle took place in the remote planet of  ... where Boo was finally defeated.
