John Doe and Goku's fused form clenched his fists, then took out a Senzu Bean from his bag, put it in his mouth, and ate it.
Immediately, he transformed into Super Saiyan Blue, and the surging blue aura was no weaker than that of Fused Zamasu.
"Since I'm the fusion of John Doe and Goku, my new name will be John Doe Goku!" he said, and the blue aura vanished, completely absorbed into his body.
At this moment, not a trace of blue aura leaked from John Doe Goku's body, as he was in the full power state of Super Saiyan Blue.
John Doe Goku assumed a fighting stance and looked at Fused Zamasu, saying, "Now, let's have our final battle, fusion versus fusion."
"I am a god, I am invincible!" Fused Zamasu roared and attacked John Doe Goku.
John Doe Goku paid no heed to Zamasu's attack. Facing the incoming punch, he simply swayed his body slightly, dodging the attack, and then struck Zamasu's nose with a punch.
Zamasu immediately covered his nose and flew backward. He removed his hand from his nose, only to see blood all over it.
"Damn you!" Zamasu wiped his nosebleed and conjured a pink sword, intending to slash at John Doe Goku.
But John Doe Goku simply raised his hand, and a blue energy blade shot out, piercing Zamasu's body and impaling him.
Zamasu quickly wrapped his arms around the blue energy blade and broke it off with force.
Zamasu, taking advantage of his immortal body, healed the wound on his body. Although he didn't suffer any serious injuries, the damage to his psyche was multiplied.
"I am invincible, I am invincible!" Zamasu roared again. The pink aura around his body slowly turned black, and his hair, eyebrows, and pupils also turned black.
This black was not the same as his black hair before the transformation; it was the black of a black hole, absorbing countless rays of light.
"A mutation or an evolution!" John Doe Goku said.
"But it's useless. It's time to end this fight," he continued. John Doe Goku charged forward, swinging the blue energy blade in his hand and attacking Zamasu.
Zamasu raised his arm, and the black aura surrounding it blocked John Doe Goku's attack.
Unexpectedly, Zamasu's power broke through again, and the two immediately engaged in combat.
"Boom, boom, boom..." Countless explosions reverberated across the sky, echoing throughout the Earth.
John Doe Goku flew forward and landed several punches on Zamasu's body, then turned and kicked him in the back.
Zamasu was sent flying like a cannonball and crashed to the ground. John Doe Goku instantly teleported in front of Zamasu, placed his hands on his waist, and fired an immensely powerful Kamehameha at Zamasu.
The powerful Kamehameha directly struck Zamasu's body.
When the light of the Kamehameha dissipated, only the lower half of Zamasu's body remained, lying on the ground.
Seeing this, everyone was overjoyed, and Vegeta shouted, "Did we win?"
The John Doe in Zamasu's body, however, had a solemn expression on his face. "No, not yet. He's still alive!"
Indeed, as the words left his mouth, the half-body of Fused Zamasu turned into mud and then reshaped into the form of Fused Zamasu.
Zamasu smiled and said, "I am invincible, I cannot be killed, but what about you? How much time do you have left? Only an hour."
"In that case, I'll blow up your entire body into smithereens," John Doe Goku said.
He charged at Zamasu again, and countless blue flashes of light sliced Zamasu into pieces.
Then, John Doe Goku unleashed a massive Kamehameha, enveloping all of Zamasu's body parts and destroying them within the Kamehameha.
However, the result disappointed John Doe Goku. The powder scattered in the air turned into small Zamasus, and they quickly inflated, growing to the height of a normal person.
All the Zamasus spoke in unison, "You can kill one of me, but can you kill all of us?"
John Doe Goku's expression changed as he looked at the countless Zamasus before him, his face turning solemn.
"What should we do now?" Vegeta asked the John Doe in Zamasu's body.
"There's only one option left, and that's to retreat!" The John Doe in Zamasu's body gritted his teeth. He never expected that the fusion of John Doe and Goku wouldn't be able to handle Zamasu.
However, the situation worsened when the fusion time of John Doe and Goku ended, and John Doe Goku separated back into two people.
Vegeta said to Future Trunks, "Trunks, quickly take Mai and leave this world. We'll hold off Zamasu for you."
Future Trunks was unwilling to leave. It was like deserting in the middle of a battle.
Vegeta shouted, "We might not die here, but if you go back, you can ask Beerus and Whis for help. If we all stay here, we'll die together."
Goku and John Doe also urged, "Trunks, listen, quickly go back in the time machine."
Future Trunks had no choice but to turn and run in the direction where Mai was.
John Doe looked at the growing number of Zamasus and sighed, "If only Beerus was willing to help us. If Beerus were here, with his strength, all these Zamasus would be destroyed."
At this moment, Goku took out a small summoning device from behind his back.
Goku shouted, "Beerus, no, but we have Zeno!"
"Zeno?!" John Doe and Vegeta immediately turned their attention to the object in Goku's hand.
"What do you mean by this?" John Doe asked.
Goku replied, "I can summon Zeno by pressing this button. Should I press it?!"
Vegeta immediately shouted, "Press it, press it quickly!"
John Doe also nodded.
Goku pressed the button, and a colorful little man appeared in front of him—it was Zeno.
Zeno looked at Son Goku, his face full of curiosity, and asked, "Who are you? You summoned me here."
Son Goku quickly introduced himself, "Zeno, I'm Son Goku. Zeno, look up there."
Zeno followed Goku's gaze and saw the dark sky, the broken ground, and the group of Fused Zamasus running around in panic after seeing Zeno.
