"Th-this…"
Goku stared at Zeru in the sky, completely stunned.
At the same time, in West City, inside Vegeta's home, Vegeta had just stepped out of his training chamber when his expression suddenly changed.
"That aura… who the hell is that?!"
Shock filled his face.
In an instant, a figure appeared in his mind—
Zeru.
"No… it can't be him, right?!"
Vegeta swallowed, his face turning pale.
It wasn't just the people on Earth who were shaken by Zeru's Super Saiyan 4 aura.
Far away on King Kai's planet, the North Kai, who had been playing with his pet, suddenly froze. His gaze snapped toward Earth.
"The Milky Way… Earth… when did such a terrifying being appear?!"
His whole body trembled. He had never felt such a powerful aura before.
"Oh? A mortal… yet carrying a trace of divine energy…"
At the same time, in Universe 7's God of Destruction realm, a man holding an angelic staff raised an eyebrow, a hint of interest appearing on his face.
"The Milky Way… Earth? Interesting. I might pay a visit someday."
This man was none other than Whis.
And he had taken a keen interest in the owner of that aura.
…
"This… is my Super Saiyan 4."
Back on Earth, Zeru slowly descended onto the beach, reverting to his base form as he smiled at Goku.
"Can I… achieve that transformation too?"
Goku asked eagerly, his eyes burning with desire.
"No."
Zeru shook his head.
"In this world, only I can achieve that form. You… should focus on reaching Super Saiyan 3 first. Only then can you think about standing on the same level as my Super Saiyan 4."
Super Saiyan 4 vs Super Saiyan Blue—
Even Zeru, as a longtime Dragon Ball fan, couldn't say for sure which was stronger.
There were countless debates online.
Some claimed Super Saiyan 4 crushed Super Saiyan Blue.
Others argued they were on the same level—
One representing pure bloodline evolution, the other a divine state.
The truth?
Still unclear.
But in this life—
He would find out himself.
Once both timelines' Goku and Vegeta reached their peaks—
He would host a cross-time martial arts tournament.
And settle it once and for all.
"Yeah… you're right. I just reached Super Saiyan 2. No point thinking too far ahead!"
Goku scratched his head awkwardly, laughing.
Whoosh!
At that moment, a figure shot through the air.
Vegeta had arrived.
"That aura just now… whose was it?!"
Even though he already knew the answer, he couldn't help but ask.
"Dad, it was Mr. Zeru's!"
Future Trunks replied.
"…I knew it."
Vegeta stared at Zeru, his expression shifting.
Who exactly was this Saiyan?
Where did he come from?
"How could someone this strong exist?!"
"You're not from Planet Vegeta, are you?"
Vegeta said in a low voice. "If you were, I would've known about you."
A Saiyan of this level—
Would've been legendary.
All eyes turned to Zeru.
"I am from Planet Vegeta," Zeru said calmly.
"But… from another timeline's Planet Vegeta."
"What?!"
"Another timeline?!"
"So he's like me?!"
Everyone was shocked.
Future Trunks was especially stunned.
He never expected someone else from a different timeline to appear.
"Do you have a time machine?"
Trunks asked.
"I don't need one."
Zeru placed two fingers on his forehead—
And vanished.
"Where did he go?!"
"Instant Transmission?!"
"He knows it too?!"
Everyone gasped.
Whoosh!
Zeru reappeared.
"My Instant Transmission is different from Goku's. You can think of it as an upgraded version… capable of traveling across time."
He smiled faintly, then looked at Goku and Vegeta.
"In the future, I will hold a multiverse martial arts tournament."
"The Goku and Vegeta from my timeline will participate."
"I hope… you'll grow stronger too—and face them in the ultimate clash across time."
"There's another me?!"
Goku's eyes lit up.
Battle intent exploded from his body.
"How strong is he?!"
"Not yet," Zeru said with a light chuckle. "But one day, you'll fight him."
"I want to see for myself… whether Super Saiyan 4 is stronger… or Super Saiyan Blue."
"Super Saiyan Blue?!"
Goku immediately caught onto the new term.
"What's that transformation?!"
"It's a form on the same level as my Super Saiyan 4," Zeru explained. "But for you… it's still far too early. One day, you'll reach it."
He didn't hesitate to reveal future knowledge.
After all—
It wouldn't affect anything significantly.
And besides—
Spoiling things felt great.
"Notification!"
"Due to the host revealing future information, igniting the fighting spirit of the original Dragon Ball Super timeline characters, you have been rewarded with a gift pack!"
"Claim now or delay?"
…
Zeru froze for a moment—
Then smiled.
This…
Was unexpectedly satisfying.
"Claim now."
He didn't hesitate.
