"I can feel his ki," Black said as he tried to sense Trunks's ki.
However, during this process, he also sensed the ki of Goku and Vegeta.
"That is. Son Goku?" He said as Goku suddenly appeared in front of him using an instant transmission.
"Yo. It's me Goku." Goku said as he introduced himself.
"You must be Black that Trunks told me about. He was right. You looked so much like me." Goku said as he looked at Black.
----------------------------
At capsule cooperation.
"That Kakarrot. He just went to the new enemy without taking me with him." Vegeta said angrily.
"How do you know it's even an enemy? It could be someone who does not pose any harm. Just like Jaco." Bulma said to Vegeta.
"The problem with that logic is that I can sense the evil ki of the person that just arrived on Earth," Vegeta said.
"Evil Ki? Does such a thing exist?" Bulma asked Vegeta.
"I am going out," Vegeta said.
-----------------------------
Goku and Black stared at each other.
Goku smiled as he went in for a punch.
Black blocked Goku's attack.
Goku transformed into Super Saiyan 2 at that moment.
"Already going Super Saiyan?" Black said as he looked at Goku.
He then punched Goku back with a fist to the face sending Super Saiyan 2 Goku flying away.
"Kamehameha," Black said as he launched a purple colour Kamehameha at Goku.
"Did I get him?" He said.
As suddenly Goku appeared in front of him in his Super Saiyan 3 form with a huge smile on his face.
Goku grabbed him by the head and tackled him to the ground.
Then dragged his head across it for a while until launching himself into a mountain.
Black immediately recovered as he got up and looked at Son Goku.
"Super Saiyan 3. Huh?" He said as he lifted his head and looked directly at Goku.
He flew towards Goku. Goku also started to dash towards Black.
They threw a punch at each other. As fists hit each other in the face.
Trunks is right. This guy is really strong. He doesn't even need Super Saiyan to keep up with me. Goku thought in his mind.
But something is strange. His ki kept increasing every time he got hit. Goku realized that there was something wrong with Black's body.
"As expected of Son Goku. You are as strong as ever." Black said as he backed away from Goku.
He wipes the blood that was on his face.
"I guess I have to be serious about fighting you. I cannot go easy on you. Unlike him." Black said as he started to transform into a Super Saiyan form.
It was not Super Saiyan 2 or 3 but just pure Super Saiyan form but just with an x50 multiplier, his power exceeded that of Super Saiyan 3 Goku.
He then kicked Goku in the head. Goku blocked his kick with his left arm by pushing it away.
Then Goku throws a punch to the gut with his right arm.
Black raised his knee to hit Goku's punch interrupting it before it could hit him.
Goku started to gather ki in his hands and created stationary large yellow ki orbs around Black.
But before he could finish him, Black created a shockwave by powering up.
The shockwave destroyed the ki orbs before Goku could attack Black with it.
Even Goku was forced to back away from Black due to the shockwave.
"This is going to be fun. I am getting excited." Goku said.
He then deformed into his base form before powering up back again into Super Saiyan God form.
"Finish Buster." Future Trunks yelled out as he launched a powerful attack at Black.
"!" Black noticed Future Trunks's arrival and dodged the attack. Gohan was also there with him.
"That must be Black," Beerus said as he and Whis also arrived at the battle scene.
"There is a time ring on his finger. It seems that our speculation about him is correct my lord." Whis noted.
Black also noticed that three other people were coming towards him at that time.
He spends too much time fighting with Goku and now there are too many people around him.
"It's been nice to meet you. Son Goku. I would have tried to learn more of your fighting style if I could but it seems that I don't have much time left." Black said as he glanced at Beerus and Whis.
"As if I would let you get away."Future Trunks said as he powered up and tried to chase Black.
But before he could reach him, Black was sucked into a small portal that took him back to Future Trunks's timeline.
"Kakarrot. Why didn't you stop him?" Vegeta asked as he arrived near Goku.
He knew that Goku could have stopped Black from escaping if he wanted to.
But he didn't and he just let Black get away without trying to hinder him at all.
"Don't worry much Vegeta. I can feel that his power is growing during our brief fight. I just want to see what is his limits." Goku said to Vegeta.
"You let him go just for that stupid reason. Act your age Kakarrot. That is the guy that is trying to kill all living beings in Trunk's timeline." Vegeta yelled at Goku.
"Hey. You also let Cell absorb 18 and kill millions of people too." Goku replied to Vegeta.
"That..... That's different." Vegeta said to Goku.
"Really. So tell me if you are in the same position as me and fighting someone who is becoming stronger as the fights progress, are you going to defeat him immediately before finding out his limits?" Goku asked.
"....." Vegeta didn't reply.
He knows that if he was the one who fought Black instead of Goku he would still let him get away for similar reasons.
According to Goku's words, Black would have been an ideal opportunity for a Saiyan.
And Goku knew that Vegeta would also think like him.
---------------------------
In the future.
"I cannot beat Son Goku, I still need to make this body completely mine," Black said as he arrived back in the future.
He seemed to be a bit disappointed by the strength that he currently possesses.
"Be patient. It will only be a matter of time. With the ability of a Saiyan that would allow their body to grow stronger every time they survived a near-death experience. Sooner or later you...."
".... No. We would be the strongest in all of the nine timelines and would be able to carry out Zero Mortal plan in all of them." A Future Version of Zamasu said as he appeared behind Goku black.
He was also wearing a time ring.
