The new Boo finds Kami-sama's palace and faces Gotenks in the Room of Spirit and Time. Gotenks starts performing weak techniques to make the battle dramatic, causing Piccolo to destroy the Room's door. Boo creates a hole in the dimension and returns to Kami-sama's where he turns everyone into chocolate before murdering them. Gotenks manages to escape alongside Piccolo, and continues facing Boo. He is then able to overpower Boo, but before he can defeat him, the fusion ends. Gohan returns, and fights against Boo. Gohan is able to overwhelm Boo, who self-destructs himself and regenerates later. Gotenks tries to face Boo again, but he is absorbed along with Piccolo. Having absorbed Gotenks, Boo is now able to surpass Gohan. The old Kaiō-shin gives his remaining life energy to Goku, along with two earrings that will allow him to fuse with Gohan. Goku attempts to give an earring to Gohan, but Gohan is absorbed by Boo before he and Goku can fuse.
