"This is Vegito blue" said Vegito as he powered up to super sayain blue or super sayain god super sayain. As he transformed gust of wind started to pick up.

"Don`t assume such a transformation will allow you to stand up to a god!" said Zamasu as he throw a big energy ball at Vegito who just catch the energy ball with one hand. The energy ball explode into bits Zamasu looked terrified cause Vegito was left unscratched.

"Now, let`s finish this. "Said Vegito.

Trunks looked at Vegito and though"The fusion between Father and Goku. What unbelievable energy!"

Zamasu started to laugh and said "Again? Once again, mortals? Mortals constantly imitate gods. Why is that? Because gods are great? Because gods are too beautiful? But, is it woeful? Is it to be pitied? What becomes good when done by gods becomes evil when done by mortals and become sin." Vegito punched Zamasu in the face causing him to bounce off the ground and Vegito kicked him and sent him flying.

"Sorry. You were way open there. C`mon mister god. I`m through listenin` to your quibbling. Hurry up and try to squash me."

Zamasu got up and said "I will not hear your repentance, mortal!" Punching the air he sent air waves towards Vegito who dodged it.

Zamasu punched Vegito in the face and sent him flying through a couple of building and then the two collide in a fury of punches Vegito kicked Zamasu in the face he tried to hit Vegito but missed and then kicked in the gut. Vegito kicked Zamasu repeatedly and then grab his head and slammed him on ground with one hand on his face and the other hand on his arm.

"What`s wrong? Is this all the power a god has?"

"Don`t be pretentious!" as his eye flashed and sent a beam at Vegito who jumped back. They both punches collided and sent gust of wind everywhere. Both of them trying to gain an upper hand on each other. Zamasu through Vegito`s hand down and then punched him in the gut and Vegito fell onto the ground.

"It`s over, mortal." As he made an energy blade and prepare to kill Vegito as he prepared to Vegito moved his head a bit. He said "Farewell!" As he lunged his sword towards Vegito stabbed him through the chest with his spirit sword. Zamasu looked surprised that Vegito stabbed him.

Vegito said "I know how to do this too. Huh? Are you in pain? Aren`t you supposed to be immortal?"

"Yes. I am immortal. I am immortal and cannot be defeated. I shall defeat you and erase all mortals and bring forth the dawn of a world that shall never be sullied."

"You sure about that? You ain`t immortal anymore and won`t be able to erase all mortals. Don`t you realize? Now that you`re fused he`ll always remain in your body a mortal named Son Goku!"

Zamasu chuckled a bit and said "Mortals truly are foolish. Son Goku shall remain in my body? Exactly! That is my wish! Listen, Sayain listen, Son Goku. You are a mortal, yet you have gained power that surpasses even gods. You are the personification of the failure of gods who created this universe!" Zamasu grabbed Vegito`s spirit sword and destroyed it and flew into the air and said "As such, by becoming one with Son Goku I have taken on the sins of mortals and the failure of gods in this body! This is truly the duty of a god."

"You always have the last word don`t you?"

Zamasu said "All of this for the universe for the world." As he started to cry.

"Are u crying?"

Zamasu said "Yes. The world will be purified by my tears! Mortal, be wiped out!" As he started to buff himself up "everything fall beneath Zamasu!"

"Not on my watch!" As he powered up. Vegito released a series of punched at Zamasu who could do nothing but block them. Vegito said "can`t that body seeped in all your rage keep up with my speed?" Zamasu swing his blade but Vegito dodged it and kicked him in the chin and kicked him away.

"This`ll end it! Final Kamehameha!" As he launched a giant beam of energy towards Zamasu when it hit the explosion caused a black hole and Vegito got sucked in.
