As Majuub and Baby begin to fight on the Tuffle Planet, after numerous failed attempts to grow his Saiyan tail, Goku ties Elder Kai to a rock and tells him to hold on to the pliers. He flies away as hard as he can, which pulls his tail out to full length, successfully increasing his energy. Back on the Tuffle planet, Majuub creates a giant energy wave and aims it at Baby to turn. After a long struggle, Baby is able to deflect the wave back at Majuub. And as a result, Majuub is turned him into chocolate and devoured by Baby just as Goku reappears through Kibito Kai's teleportation only to see this incident, too late to save him. Now fueled by the loss of his trusted partner, Goku arrives and powers up to Super Saiyan 3 for a rematch after Baby discovers that Goku is still alive and he now has a tail. But even with his tail back, he does not seem to have gained any strength. Goku then charges at Baby, but the evil Tuffle grabs him by his tail (golden while in Super Saiyan 3), swirls him around in the air and throws him back to the ground, badly injuring him and causing him to regress back to his base form as he loses Super Saiyan 3 permanently. As Baby flies down to finish him this time, the now-depressed Goku realizes he is again no match for his foe, and then looks up at the Earth in the sky of the Tuffle Planet. Remembering his life with his friends and family on his home planet, and unable to bear his failure to protect them from Baby, Goku pleas for the power to "end this madness". Surprisingly, Goku absorbs the familiar energy reflecting off the Earth, the Blutz Waves, causing his tail to have a reaction, his heartbeat to increase by the time his eyes turn red, and his body to bulge. And then, he powers up in a gigantic Super Saiyan aura, finally transforming into a Great Ape: this time with golden fur (including his spiked hair). Though stunned by Goku's amazing new transformation, Baby refuses to believe that Saiyans can change into Great Apes without the full moon, until he realizes in horror that Goku has used the Earth as the moon's resemblance.
