Unknown to the others, Buu secretly separates part of his back, and the two pink blobs creep around behind the others. As soon as Goten and Trunks fuse, one of the blobs encases the Saiyan. Piccolo, too, has been covered by a pink blob. Buu calls each of the blobs back to him, and they combine to form a Super Buu that's even stronger than he was before. Buu and Gohan start to fight, and it's clear that Super Buu has the advantage. Gohan seems unable to keep up with Buu's new speed and strength. Buu taunts Gohan by telling him what his three friends that were absorbed think of him.
