He then proceeds to destroy Super 17 with a barrage of energy blasts. Goku uses this form on Super 17 when he realizes he cannot combat him as a Super Saiyan. Baby decides to leave Vegeta's body, and the planet, but Goku fires another kamehameha, blasting Baby into the sun and ending Baby's reign of terror. He then uses a kamehameha to blast off Baby's tail. Goku, using his Super Saiyan 4 strength, absorbs, Baby's Revenge Death Ball Final. Goku friends were freed from Baby's control, and proceeded to assist Goku, but he insists that they don't fight, as they are not strong enough. Still, Goku has the advantage in strength, so Baby uses more Blutz Waves to recover. Goku has the upper hand in this fight, so Baby uses Blutz Waves to transform himself into a golden great ape. Baby sense him coming, and after a conversation with Baby-possessed Bulma, Goku and Baby fight.

After achieving it, Goku orders Hercule to take care of Pan, while he proceeds to fight Baby Vegeta. Goku achieves Super Saiyan 4 out of Pan's crying that he may never return to normal again. In this form, the saiyan's personality becomes that of a great ape, sometimes brash, but is able to control his/her actions while in this state. The Super Saiyan 4 form's general appearance is that the saiyan is covered in reddish fur, saiyan gains his eyebrows again, hair is extended (Not nearly as long as Super Saiyan 3, though), the saiyan gains a reddish fur tail, and upperwear completely disappears.
