West City.
Capsule Corporation.
Bulma had already returned home from the hospital a few days ago.
In that short time, Trunks had grown familiar with every corner of the house, and he was genuinely pleased with his new environment.
After all, he was now the son of the richest woman on the planet.
From this point on, he no longer had to worry about food or shelter; his path forward would be fully dedicated to training and growth.
In the original timeline, both he and Goten had achieved the Super Saiyan transformation at just seven years old— a clear testament to their potential.
Now, with a long future stretching out before him, all he needed to do was pour his heart into training and sharpening his power.
Over these few days, Trunks had experienced deep, unconditional maternal affection and along with that, he noticed a subtle shift in Vegeta.
The man who once spent every waking moment training— eating, sleeping, and returning straight to the gravity chamber had begun to change.
Now, after each session, Vegeta would come check in on Bulma and the baby. He wouldn't say anything, of course. Saiyan pride wouldn't allow it. But with arms folded across his chest, he'd hover at a distance, silently watching them.
Bulma had caught him like this more than once. Each time, it made her heart melt.
The days passed in this rhythm— until today.
BOOM—!
A deafening shockwave thundered out from the gravity chamber, its echo rolling across the land for hundreds of miles.
Flashes of gold and white Ki surged into the sky, tearing through the reinforced walls of the training chamber.
"RAAAAAAAHHHH!!!"
A primal roar exploded into the heavens. It was unmistakably Vegeta's voice.
The sheer pressure of the moment jolted Bulma, making her head snap toward the gravity chamber.
At the same time, the baby in her arms stirred, his small face lifting toward the surging energy.
(This must be the moment, right before the Androids appear.)
(After the warning from my future self, everyone began pushing themselves to the limit.)
(And right around now… this is when Dad finally breaks through, when he becomes a Super Saiyan.)
The wild energy bursting from the chamber swept through the surrounding area, sending the flowers and plants in the garden into a frenzy, petals spinning through the air like confetti.
Bulma held Trunks tightly, bracing against the wind, and took a determined step toward the gravity chamber's doors.
"Vegeta! What on earth are you doing?!"
But her voice was drowned in the storm of power. Vegeta didn't even glance in her direction. His focus was absolute, he was concentrating everything within himself, igniting the fire in his core.
In Bulma's arms, Trunks fell silent, holding his breath. His gaze locked onto the roaring pillar of light erupting from the training grounds.
He knew exactly what Vegeta was doing.
White and golden auras spiraled together, each more intense than the last, surging upward in explosive waves.
Vegeta was pushing past his limits, and he was on the brink of ascending.
The roar deepened, becoming more savage, more desperate. His ki became unrestrained, shaking the very earth beneath him.
Trunks watched without blinking.
(His battle power is at the tipping point. He has what it takes to transform.)
(But there's still something… missing.)
At that moment, the mysterious voice once again echoed through Vegeta's mind— clear, deliberate, and impossible to ignore.
His aura wavered. The power flow stuttered.
[That voice again?!]
Meanwhile, Trunks' own memories— echoes from a life lived in another world— resurfaced.
In Dragon Ball Super, it was revealed that the Saiyans from Universe 6 used a unique method to trigger the Super Saiyan transformation.
(Concentrate all your energy into your back… gather and charge the S-Cells at the spinal core.)
Vegeta's eyes widened. His pupils constricted.
He'd heard it. Every word.
[How dare you presume to instruct this Prince?!]
At that moment, Vegeta's brows knit tightly together, and his eyes twitch with suppressed fury.
"RAAAAHHHH!!!" His roar erupts once again like thunder cracking through the skies.
Watching Vegeta burn with rage, Trunks can't help but feel gleeful on the inside.
(Yes! That's it! The angrier he gets, the closer he'll come!)
(If only I could push him further… Maybe something even more infuriating— like the disgrace of being overtaken by a low-class warrior!)
Vegeta stands rooted to the spot, the mysterious voice echoing in his mind like a dagger to the chest.
Without warning, memories of Kakarrot's first transformation— of Son Goku ascending into a Super Saiyan— flash uninvited across his consciousness.
Though his pride screams in protest at this invisible voice trying to guide him, the truth is undeniable: his Ki is soaring beyond anything he's ever felt before.
He can sense it. He's standing on the edge of the impossible. One more push, one more surge of emotion, and the transformation will be his.
Indeed, fury is the key.
Vegeta grits his teeth. He loathes the idea of being instructed by some ghostly whisper, but the result is real.
[Hmph… This voice may be aggravating, but it isn't wrong.]
[Fine. Let's see what happens when I channel all my energy into my back!]
"RAAAAAAHHHH—!!!"
With a howl that seems to split the clouds above, Vegeta focuses the full might of his energy toward the center of his back.
In that instant, the dormant S-Cells deep within him begin to stir. Slowly but steadily, they awaken— pumping raw, explosive power into that single focal point.
Bit by bit, the change begins.
Vegeta's pupils narrowed, shifting from black to a piercing shade of green.
Then, with a surge, golden light washes across his body, racing up from his spine, illuminating his eyes, and bleeding into his eyebrows and hair.
In the blink of an eye, the transformation is complete.
His muscles tighten, his aura crackles with divine golden fire, and his hair blazes upward like a burning crown. The shimmering golden glow flickered across his skin, giving him an aura of unmatched power and authority.
There's no doubt.
Vegeta has finally achieved the legendary state of Super Saiyan!
"Hahahaha!!!"
"Super Saiyan! I did it! KAKARROT!!!"
His laughter echoes across the sky— wild, triumphant, filled with years of buried frustration and relentless determination. From the moment he first learned of Son Goku's transformation, Vegeta had thrown himself into brutal, unending training, waiting for this very moment.
Outside the gravity chamber, Bulma's eyes go wide.
As Vegeta's wife, watching him break through the limits of his own body and pride, her heart swells with joy.
"YES! Vegeta! I knew you could do it!"
But inside, Vegeta is so focused, so consumed by the aftershock of power, that he doesn't even notice the presence of Bulma and Trunks just outside the door.
It isn't until he hears her voice that the flame of his excitement begins to settle.
Breathing slowly, Vegeta walks toward the exit.
And though Bulma beams with pride, hoping for at least a smile, he offers no such reward. His expression remains cold and distant.
He simply mutters, "I'm hungry."
With that, Vegeta turns on his heel and strides past them, vanishing down the hallway, leaving Bulma and Trunks in his golden wake.
Bulma watches him go, hands on her hips, eyebrows twitching in annoyance.
"Hmph! So much for gratitude. I cheer him on and get nothing but a cold shoulder in return!"
Still grumbling, she pulls out her capsule corp intercom and calls the kitchen.
Time to prepare a meal worthy of a Super Saiyan.
