Dragon Ball GT S01 E13 The Man Behind the Curtain

Goku and Trunks have defeated Cardinal Mutchy Mutchy, and now stand before the awakening Luud. When Dolltaki refuses to give up Pan to the ever-growing monster, Dr. Myuu feeds both Pan and Dolltaki to Luud! This sacrifice brings the machine-mutant so close to full operating power that Goku and Trunks alone will be no match for it!
