When Goku refuses, the Tuffle parasite insists on destroying him instead. Goku powers up to Super Saiyan 3, but finds that with his new body, he can't reach his full power, or defend himself as well. Baby begins to pummel Goku, who is now helpless. Gohan, Goten, Trunks, and Bulla each give all of their energy to Baby, who takes on a new form and overpowers Goku with one punch. He then gathers energy from everyone on Earth and changed into another new form.
