Chapter 12: Super Saiyan 4, and Entering the Time Chamber Again!
---
After finally defeating Son Goku, Trunks smirked arrogantly. But once he returned to his normal form, that smirk turned into a genuine smile of joy.
[Ding! Son Goku has been defeated!]
[Acquired Son Goku's skills and abilities!]
[Acquired Super Saiyan 4 Advancement Card!]
[Acquired 2 billion power units!]
Hearing the system's voice, Trunks was in pure bliss.
He felt a massive surge of power flow into his body, along with Goku's fighting experience and techniques.
Looking over techniques like Super Kamehameha, Instant Transmission, and Kaioken x20…
Trunks was itching to train and master his newfound strength.
"Uncle, are you okay…?"
As he approached Goku, who was sitting on the ground in exhaustion, Trunks felt something strange.
How could someone who was already dead feel drained of energy?
He shook his head, glanced at Goku's condition, and silently thanked the system for granting him infinite stamina—similar to what he gained after defeating Android 18.
He definitely didn't want to end up like this every time he used Super Saiyan.
"So, Dad… just as you agreed with Trunks, you'll accept being revived, right?"
Looking at Goten's hopeful smile, Goku returned the gesture with a warm grin.
"Of course… but I still want to train on King Kai's planet."
Seeing Goku's expression, Trunks felt the urge to laugh at his uncle's foolishness.
"Uncle Goku… you do realize you can always come here to train using Instant Transmission, right?"
"Oh… you're right! Why didn't I think of that!?"
King Kai looked at Goku silently.
He had told him this many times before, but Goku always refused, using Chi-Chi as an excuse.
But watching this now, King Kai understood. Goku truly wanted to return.
To live with his family, to see his friends again.
And perhaps, after being defeated by Trunks, he no longer minded coming back—since he had found a worthy rival to fight whenever he wished.
"Well then, Uncle Goku… we'll leave now. We'll bring you back soon!"
"Of course… see you then."
Trunks and Goten said their goodbyes to Goku and King Kai. They didn't even wait for their time in the Other World to expire—
they simply returned to Earth.

"Goten, what do you say we enter the Hyperbolic Time Chamber for training… then afterward, we'll look for the Dragon Balls to revive your father?"
Hearing that, Goten's eyes sparkled and he immediately agreed.
After witnessing Trunks' growth from the chamber, he was eager to become stronger as well.
So, they went to Kami's Lookout, where Piccolo, Dende, and Mr. Popo greeted them.
"Trunks, you're not joking, are you?" Piccolo asked.
"No… Goku-san really agreed to be revived."
Upon hearing this, everyone felt overjoyed.
The return of Goku meant their friend would come back, Earth's protector, and the strongest fighter alive.
…Or maybe not, since after being defeated by Trunks, that title might belong to him now.
"In any case, Dende, can you allow me and Goten to train in the chamber?"
"Of course… I'll prepare it for you right away."

Soon enough, Trunks and Goten began their harsh training inside the Hyperbolic Time Chamber.
Goten still struggled with the gravity inside, but he was adapting little by little.
After a short sparring session, the two separated to train individually, with Trunks giving Goten some pointers to improve his efficiency.
"And now… System, use the Super Saiyan 4 Advancement Card!"
Trunks was thrilled for Super Saiyan 4.
Although he also wanted Super Saiyan God and Blue, the system told him he first needed to defeat a Saiyan with God ki or somehow obtain divine energy.
But Trunks wasn't disappointed. After all, Super Saiyan 4's power rivaled Super Saiyan Blue—and with divine ki, it could even surpass it.
"Heeeya! Haah!"
Goten threw rapid punches, now getting used to the chamber's conditions.
But suddenly, he froze and looked at Trunks in shock.
Trunks' power was skyrocketing at a terrifying pace—just like before.
"Wait… is Trunks about to evolve into Super Saiyan 3 like Dad…?"
Little did he know, Trunks already had Super Saiyan 3.
The energy surged wildly, and Trunks' body began to expand unnaturally.
At that moment, Goten noticed Trunks was transforming into a giant ape—Oozaru!
He remembered seeing a tail on Trunks not long ago.
When he asked, Trunks told him Vegeta had explained that Saiyans with tails could transform during a full moon.
Vegeta even mentioned the Ikari form, which boosted power tenfold without fully transforming into an ape.
But now, before Goten's eyes, Trunks' body grew at a frightening rate—until he became a massive golden-furred ape.
Gulp!
Goten trembled in fear.
Trunks' power kept rising, even in Oozaru form.
Then, he shivered as a bad feeling washed over him.
"W-wait… is that… Super Saiyan!?"
Before his very eyes, the ape's fur shifted from silver—matching Trunks' hair—to shimmering golden!
[Ding! Super Saiyan 4 Transformation process has begun!]
Hearing the system's voice, Trunks calmed down.
He had feared losing control, since the Oozaru state turned Saiyans into mindless beasts.
But as he thought of Goten's safety, his transformation accelerated.
Golden lightning crackled across the void as his body shrank down—
until a completely new figure emerged.
"W-who is that…? That's not Trunks!"
Before Goten stood a tall, handsome young man with long, wild, silver-purple hair and a lean, muscular build.
He was shirtless, with crimson fur covering much of his body.
Golden eyes shone with confidence, and a smirk played across his handsome face.
Goten hesitated, but a thought struck him—
could this be… Trunks?
"Y-you're… Trunks… right?"
Trunks simply smiled.
That was enough for Goten to laugh in relief and excitement.
"This is… Super Saiyan 4!"

I'll be dropping all the chapters I currently have—around 7 today.
I really hope to see some feedback because honestly… I'm starting to lose my passion.
