7x21 - Dragon Ball Z: Dragon Box

Boo begins using the attacks of those he has assimilated, including Gotenks' Super Ghost Kamikaze Attack, Piccolo's Masenko, and Gohan's Kamehame-Ha. However, by using Instantaneous Movement, Vegetto is able to evade all of them! Finding himself backed into a corner, Boo gets himself close enough to Vegetto, and then without warning, uses his transformation beam against him, turning Vegetto into a hard candy!
