Because Son Goku had shown mercy time and again, Baby's power had surged thanks to Bulma's assistance. Son Goku could not be certain if Bulma would be able to build another machine to increase Baby's power even further.
This time, Son Goku was truly moved to kill.
"Revenge Death Ball!"
Seeing the vastly empowered Son Goku charging toward him, Baby let out a roar. He immediately raised both hands, and the energy within his body condensed frantically, manifesting into a massive, pitch-black energy sphere.
"Go to hell!"
Baby hurled the Revenge Death Ball toward Son Goku with both hands.
"Baby, watch closely. This is the true power of a Super Saiyan 4."
Super Saiyan 4 Son Goku said with a cold expression, watching the energy sphere, which spanned over a hundred meters, hurtling toward him.
As soon as he finished speaking, Super Saiyan 4 Son Goku kicked out fiercely at the Revenge Death Ball.
Perhaps the Revenge Death Ball had been formidable to the previous Son Goku, but to the current Son Goku in his full-power state, it was nothing at all—it was simply fragile.
BOOM...
The massive Revenge Death Ball, capable of destroying a planet, instantly collapsed the moment Son Goku kicked it flying into the sky.
"How is this possible? He kicked my Revenge Death Ball away with just one kick?"
Horror filled Baby's eyes. He knew exactly how powerful his Revenge Death Ball was, yet it had been kicked away by Son Goku with such ease.
Baby was shocked to his core, and before he could react, Son Goku suddenly moved.
Son Goku took a single step forward, and his entire figure instantly appeared right in front of Baby.
He clenched his right hand into a fist and unleashed a fierce punch.
Compared to Baby's massive frame, Son Goku's fist looked incredibly small, yet that seemingly tiny fist was filled with terrifying power.
"Impossible..."
Under the impact of that punch, Baby spat out a mouthful of blood, clutching his stomach as he stumbled backward repeatedly.
Son Goku did not give Baby much time; he charged forward again, throwing another punch. Perhaps this time, Son Goku was truly intent on killing.
BOOM...
Baby retreated once more, his expression twisted in even greater agony.
"Son Goku, you know that if you kill me, Vegeta will die too!"
In the midst of this life-or-death crisis, these words escaped Baby's lips.
Hearing what Baby said, Son Goku's movements paused for a moment; he hesitated.
Just then, Lei Chen's voice rang out from the distance.
"Kakarot, cut off his tail!"
Hearing Lei Chen's words, Son Goku's face instantly lit up with joy. Without waiting for Baby to speak again, Son Goku closed the distance, his punch transforming into a gale that forced Baby back once more, causing him to spew blood.
Bang! Bang!
After Son Goku landed several consecutive punches, he waved his right hand, and a wave of energy surged out, heading straight for Baby.
By this time, Baby had already been beaten unconscious by Son Goku and lay on the ground.
The golden energy wave struck true, landing directly on Baby's tail.
Without his tail, Baby's body could no longer maintain the Great Ape form and instantly reverted to its normal size.
Having returned to his normal state, Vegeta's body could no longer support Baby's continued fusion.
After all, during the fusion process—especially after transforming into a Great Ape—Baby's body had grown along with the ape form.
But now, as Vegeta's body returned to its normal size, it could no longer withstand Baby's continued presence.
If he remained inside Vegeta's body, he would be crushed to death by the physical form itself.
However, if he left Vegeta's body, he would face Son Goku and Lei Chen outside, making it extremely difficult to escape.
But between dying immediately and having a chance to flee, Baby chose the latter.
Going out meant he might die, but staying inside Vegeta's body meant certain death.
