""You die, dummy!""
True Worth Beginning to Show The Treacherous Buu! (見え始めた真価 反逆のブウ! Mie Hajimeta Shinka Hangyaku no Majin Bū!) is the one hundred thirty-fourth episode of Dragon Ball Z Kai. Its Japanese air date is October 26, 2014.
Trunks arrives at Capsule Corporation and inquires with his grandfather and grandmother about the location of the Dragon Radar, but Dr. Brief struggles to remember. Meanwhile, Goku is fighting Majin Buu at Super Saiyan 3. Bulma eventually remembers the radar is still in the Airplane and borrows Videl's phone to call Capsule Corp. Goku continues stalling for time for Trunks until Bulma calls and he finds the Radar. When Trunks leaves, Goku powers down and tells Buu and Babidi that a fighter even stronger than himself will fight Buu in two days. In return for a good fight, he asks Buu to stop destroying cities until then. Goku also tells Babidi that King Yemma will make him suffer when he dies before returning to The Lookout. Babidi then blames Buu for Goku's escape, calling him names. Majin Buu then announces he has a "good idea" before proceeding to grab Babidi by the throat (to prevent Babidi from sealing him away). Buu declares he no longer needs Babidi before punching the wizard's head off.
