One Piece: The Eldest Brother

…

Surprise and shock were written on everybody's faces when they saw who saved Goku Black since it was Zamasu!

Trunks, Vegeta, and Goku had come with the knowledge that Zamasu had taken Goku's body but the truth was a lot more complicated.

The new Zamasu then used his power to heal Black to top shape.

It was Vegeta and Trunks who realized the truth of the matter, being that Zamasu of the past took Goku's body before going to a future timeline to ally with his future self.

Anyway…

The battle then resumed its course, but it twisted in another direction altogether, as Black slowly equaled and overpowered Vegeta even though he was in his Super Saiyan Blue form.

With Zamasu on the side healing Black while raising his battle power, the fight quickly turned into a disadvantageous situation for Goku and Vegeta. The two were taking full advantage of the Super Saiyan's hallmark to power up by reviving from the brink of death.

But the crazy part of it all happened when the new Zamasu once again healed Black.

"Yes, that's it!" Black said with a very excited and nasty look on his face. "Every time my cells regenerate from taking damage, it becomes more and more my own!"

"My divine soul and this Saiyan's body are becoming one!" Black closed his eyes to feel the power overflowing in his body with an exhilarated expression on his face.

He opened his eyes in the next second and grinned at Vegeta. "I have reached a state that mere mortals like yourselves could never hope to attain…"

"Haaaah!" His ki suddenly and shot up to the sky and unleashed a dreadful aura out as he yelled.

And to the surprise of everyone present, Goku Black's hair turned in light pink while his body was encompassed in a contradicting malicious dark-pink divine aura.

"Why are you pink!?" Goku asked with a confused expression.

And then the other Zamasu reacted with an enlightened face. "So when a Divine Being surpassed the Super Saiyan God, they turned pink instead of blue, how interesting."

"Should we go together now, Vegeta?" Goku asked with a wry expression.

"Hmph, just do something about that bastard over there, I won't get anywhere if he keeps healing him over and over again…"

"Alright then…" Goku agreed with him before telling Zamasu to move elsewhere.

However, the number of plot twists was excessively huge today because the Zamasu that Goku was fighting revealed that through the use of the super dragon balls, he gained immortality!

…

… 

That news sent a shock to Edam of course, but his mind was worried about something else.

"Uh, he is pink…?" Edam watched on with a twitching expression. "I won't turn pink too right?"

Yamote only shrugged his shoulders, not replying seemingly unaware of it.

"Well… a bit yes…" Yamote said and reflected on something. "And this is immortality granted by the Super Dragon Balls…"

"..." Edam fell silent and then started to type down on his keyboard. "Then, let's cheat too…"

[How to kill immortals?]

Following this, a few possible answers pop up in front of him. Most of the time, the majority of the answers would only be theories posted on the God Multi-U-net. And since they were personally verified before being posted, they were all serious answers and not trolls.

[If it's a Vampire, use a holy cross, and holy water, etc… link in the description.]

Edam lifted a brow and clicked on the link. He was sent to another page where a video of a vampire being exorcised was played.

"Okay, hmm…" Edam said and then read something else.

[If it's undead, a cursed spirit, or other, uses sacred or cursed power, etc… click for more information.]

'He's definitely not an undead and I don't even know sacred or cursed power, but let's see…'

"Wow, which universe is he from? Outer Side? Interesting..." Edam said and looked at something else.

[Do consider inflicting eternal pain to your target.] The video showed a strange method to inflict constant pain on a target.

But then his attention was drawn toward the next answer to his questions.

"Oh, that might do…" 

[If none of the solutions suggested works, you can opt for a sealing technique, link in the description.]

Clicking on the link, he was sent to a new page, where different things were shown, and one of the examples especially drew his attention.

It actually showed Beerus! Yes, the purple cat Destroyer who even Goku and Vegeta seem to be a bit fearful of. He was shown sealing an old Supreme Kai in a long and greatsword.

"Hmm? A Destroyer sealing something, wouldn't it be easier to just destroy him?" Edam curiously asked Yamote.

"Ah, oh, well, each Destroyer is life-bound to their Universe's Creation Gods, if all Grand Supreme Kais were to die, the said Destroyer would follow after to ensure a balance in the Creation and Destruction cycle… Maybe Beerus had foretold this old kai's death and so decided to seal him?"

"Yes, actually, that Zamasu there surely killed all Creation Gods, eliminating the Destroyers at the same time thanks to that link..." Yamote explained but then noticed Edam's disinterest in that.

"Alright, thanks for the info…" Edam thanked him and took another look at Beerus' sealing technique. "Very well…"

…

*On Goku's side* 

In a moment of carelessness, when Goku saw that he got the advantage on the Immortal Zamasu, he retrograded to a basic Super Saiyan form and so carelessly let down his guard, and finally found himself defeated by the Immortal but somewhat weak Zamasu who perhaps even Edam would have had his fair chances against if given the chance to. 

Furthermore, Vegeta was already overwhelmed by Black's Super Saiyan Rosé's form. 

And so, since the solution was not looking very good, Trunks worriedly ran to his father and told Goku that they should retreat for now under the mockery of Black and Zamasu.

"Goku! Mai! Shield your eyes!" Trunks shouted and then placed his hands on both sides of his face before shouting again.

"Taiyoken!!!" A fierce and blinding light abruptly erupted from Trunks, literally blinding everyone who had their eyes opened, as if a sun had suddenly appeared.

When they recovered their sights, the team was already far away.

"Dammit, where are they?!"

"Do you sense them?" Damask asked Black and he replied.

"These Saiyans know how to hide their energy-…" Black then said with a frown, and then turned in another direction. "Wait a minute…"

As he did that, his eyes stared at a rather far away distance from where he stood and finally met another pair of eyes, a pair of pale yellow eyes.

"Huh? Wait what, why is there another Saiyan here?" Zamasu asked curiously.

"...This guy is…" Black murmured before bursting into speed.

However as he was about to reach and strike him, his punch slightly missed as he watched Edam falling back into a spatial gate, disappearing into it.

"Shit!" Black mumbled angrily while Zamasu asked him.

"Who was that?" Zamasu asked, unaware of who that person could possibly be.

"That's exactly what I wanna know…" Black muttered while silently pondering. "He was in the past when I accidentally traveled there but…"

"... I've never met him either, how is that possible…? I just came back from the other timelines but never met this guy once…" Zamasu frowned.

…

… 

*Back to Goku & co's side*

The four were in a sewage tunnel walking while reflecting on a way to neutralize Zamasu. His immortality and ability to heal Black were the most bothersome to deal with.

They were walking while talking about their strategy when a portal opened up right in front of them.

"Shit, they already found us!?" Trunks shouted with a kind of despair in his voice when another voice replied from the gate.

"Hey hey, calm down, it's me…" Edam walked out and greeted the four people.

"E, Edam!?" Goku and Trunks both exclaimed out loud in clear shock. "Bu- But how can you be here!?"

"Well, Yamote's got the formidable ability to manipulate Time to a certain extent…" Edam said and presented Yamote to them.

"Then, why did you follow us?"

"I had wanted to use the super dragon balls, but that immortal dude just had to destroy them afterward…" Edam said with a deadpan expression. "And I can't return back since the connection to the Time hole is too weak for Yamote to use it as it is now…"

"So, what is your plan?" Edam asked them and Trunks replied.

"Well, my plan was to…" He explained his plan in detail.

…

… 

At the same moment, outside.

"Wait, although I can't sense the Saiyans' ki, there's still that woman's ki…" Black smiled, took hold of Zamasu, and then teleported both of them.

They instantly arrived at the destination and saw Mai and four other silhouettes walking discreetly while covered by some sheets.

"Stop wasting your time and-..." Black didn't get time to speak as Mai angrily slapped the sheet covering her away while taking her gun out and firing at the two deities.

At the exact same time, a furious Super Saiyan 2 Trunks suddenly jumped out of somewhere with his sword pointed at Zamasu and fiercely pierced Zamasu's back like a skewer.

Edam then appeared already in his semi-wrath state and directly dashed toward Black and punched him hard making him fly and crash a dozen meters away.

"My father and Goku aren't here, sorry for you!" Trunks shouted.

Meanwhile, Goku and Vegeta were already in the time machine about to travel back in time.

Black and Zamasu tried to interfere again but his way was blocked again by the two young men, one in a Super Saiyan 2 who could equal to some extent a Super Saiyan 3, and the other one was a strange Saiyan with an unknown transformation that could reach unknown power.

"You damn…!" Black could only look in anger and humiliation as the time machine blinked out of his eyesight. "Bastard!"

Black's eyes were filled with hate and anger as he looked at the two guys responsible for that.

The pressure of a divine being washed over them while Edam glanced at Trunks and Mai who were just beside him.

"Trunks, I think we should go now…" He said and grabbed both Trunks and Mai.

But, to his surprise and shock, Trunks only smiled back at him. "You go, Edam, I will stay here…"

"What?" Edam thought his ears malfunctioned for an instant and he heard it wrong.
