Unlike his other forms, Kid Buu has zero sanity, empathy, remorse, or higher-level thought. • He fights strictly for the joy of chaos and instantly tries to blow up the Earth with a Planet Burst attack rather than toying with or talking to his opponents. • Erratic Combat: He laughs hysterically, bounces around unpredictably, and even tears his own body apart or blows up the planet just to follow Goku and Vegeta to the Sacred World of the Kais. The Final Battle • The Climax: Kid Buu fights Goku (in Super Saiyan 3) and Vegeta on the Sacred World of the Kais, while Good Buu and Mr. Satan step in to buy time.

• When Planet Earth is destroyed, the Supreme Kai uses his Kai Kai instant teleportation to rescue Goku, Vegeta, Mr. Satan, Dende, and Bee, bringing them safely to the Sacred World of the Kai. • Panic and Fear: Unlike Goku and Vegeta, who get excited or determined to fight the pure-evil Kid Buu, the Supreme Kai is deeply traumatized and terrified of him because he witnessed firsthand millions of years earlier how effortlessly Buu slaughtered and absorbed his fellow divine peers

• After Old Kai sacrifices his own life force to restore Goku's life, Goku enters the final confrontation against Kid Buu as a fully living mortal once again (rather than fighting on a 24-hour clock). • Exhausted and Determined: Goku is visibly angry and emotional upon finding Kid Buu—vowing to make him pay after discovering that Buu destroyed the Earth and killed his family and friends.

After being wished back to life by the Namekian Dragon Balls (Porunga), Vegeta steps up to formulate the battle plan on the Sacred World of the Kais while Goku battles Kid Buu.
