Buu Gobbles Up Buu! Onlsaught of a New Majin! (ブウがブウを食べちゃった 新たな魔人襲来!! Buu ga Buu O Tabechatta Arata na Majin Shūrai!!) is the one hundred forty-second episode of Dragon Ball Z Kai. Its Japanese air date is December 21, 2014. Its American airdate is December 9, 2017.
Majin Buu attempts to fight against the Evil Buu, but he finds out that he is much weaker. Most of his power had been transferred over to his evil side. As a result, Evil Buu manages to reflect Majin Buu's candy attack back at him, turning him into chocolate, before eating him. This allows Evil Buu to gain Majin Buu's power, which gives him a more complete form. Sensing the energy of Piccolo and the others, Super Buu arrives at The Lookout and demands to fight against Gotenks. Piccolo attempts to stall for time by telling Super Buu to wait until all of the Earthlings are killed. Piccolo instructs Krillin to bring Goten and Trunks to the Hyperbolic Time Chamber, in order to make use of what little time they have.
