Buu's thought process is seen to be irrational and spontaneous, even destroying his own body to destroy the Earth. Buu doesn't say coherent words, just blabbers. Although Kid Buu appears smaller than any other form, he is more dangerous than any other forms of Buu due to his full relentless evil and unpredictability. Buu's speech is VERY incoherent. Buu hates everything and everyone. Buu wants to destroy everything and everyone with no EXCEPTIONS. Kid Buu has extremely immense regeneration.
