Vegeta's eye twitched, his aura flickering like a barely contained explosion.
"Tch… ridiculous. Absolutely ridiculous…" he muttered, arms crossed so tight his muscles trembled. But beneath the anger was something even sharper—pride that he refused to admit.
Goku floated down beside him, grinning wide.
"Wow! So you came up with all that just because you lost once?" he said, sounding more impressed than anything. "Man… I gotta say, that's… actually pretty awesome!" He scratched the back of his head. "I usually just train harder. But making a whole new transformation? That's a new one."
Piccolo narrowed his eyes.
"So you altered your bloodline. That explains the sudden spike in your aura." His expression was stern, but not hostile. "Still, to pull something like that off… you're definitely not the same kid you used to be."
Krillin let out a long whistle and shook his head.
"Yeah, no kidding. Remind me never to spar with you unless Goku's around. Or Vegeta. Or… uh… anyone stronger than me."
Android 18 crossed her arms with a smirk.
"He's not joking. I felt that power from across the battlefield. You're insane."
Tien nodded respectfully.
"It takes discipline to reinvent yourself like that. Impressive."
Yamcha quickly nodded too—trying very hard not to look intimidated.
"Uh—yeah! Totally impressive. Super impressive." Then he leaned toward Krillin. "We're sure he's still on our side, right?"
Bulma pushed her way through the group, tapping a capsule computer aggressively.
"Okay, okay—everyone shut up for a second. You changed your bloodline? As in permanently? Do you have any idea how many tests I'm running on you later?! You don't get to say no!"
Chi-Chi exhaled slowly, holding her head.
"Why can't any of you boys ever be normal…?"
Goten popped up beside Trunks, eyes sparkling.
"Bro, that was so cool!"
"Yeah!" Trunks added, crossing his arms proudly. "If losing to me made you that strong, maybe you should lose to me more often!"
Vegeta snapped instantly.
"Trunks! Don't you dare encourage him!"
Gohan was still smiling at you, his hand resting easily on your shoulder.
"Regardless of how you got here… you made the right call today. And if you ever need help mastering that new form, just say the word."
The others murmured in agreement—some excited, some confused, some terrified—but all of them united in one thing:
They were taking you seriously now.
And Vegeta, after a long moment, finally spoke again—this time quietly, almost grudgingly.
"Fine. If this is the path you've chosen… then you'd better not embarrass the Saiyan race. Understood?"
His eyes burned—not with anger, but with challenge.
"Hahahahahaha you don't have to worry about that also you seem to be misunderstood me when I said I changed my bloodline my current apprance actually is my preference as for why a white tiger simple I think transforming into a massive white tiger is way cooler and better then a giant ape in the full moon as for what my bloodline is now you it's more like a mutation". I said getting everyone attention.
" Kai, care to explain". Bulma said hardly containing the the excitement cause she had a feeling I'm about to tell them a major secret.
Well you see I did some digging in the Saiyan history and guess what I found the transformation that we were that we were doing up till now . From super Saiyan to super Saiyan 3 were actually a natural innate ability any Saiyan can do when reaching a certain power level.
" I say to them calmly as my white tiger tail sway left and right.
"Hold on an innate ability then are saying that kakarot isn't the legendary super Saiyan in the in old tales of the Saiyans". Vegeta ask sticking the dotes toghter while looking at Goku with a shocked expression waiting for my confirmation.
"Bingo , you see the legendary super Saiyan in the old tales and legends of the Saiyan is actually a mutant of the Saiyan and there is one alive now he should be around. 40 years old now ". I answer Vegeta question with a grin.
"40 years old isn't that the same age as you Goku". krillin spoke hesitantly.
Goku remained silent trying to gather his thoughts toghter.
"Don't tell me you changed your bloodline into that of a legendary super Saiyan then removed the ape trait from it and placed the white tiger trait instead ,causing your current apprance and power spike? ".Bulma spoke her mind quickly gathering the dots.
"Yes that's exactly what I did expet that my power spike was because my training and my good training ground along with the resources I used . As for my appearance its my choice I asked rose to give me those . Tiger tail ,ears, sky blue eyes , white long hair and some fangs too cause I wanted too". I answer Bulma.
Bulma's eyes sparkled like she'd just discovered a new universe to poke and prod.
"Oh, this is incredible! A completely custom-designed Saiyan mutation? Kai, you have no idea how many tests I'm going to run on you. I need blood samples, hair samples, energy readings—oh, and don't even think about running away!"
Vegeta snapped, "Bulma! Focus!"
He turned back to me, jaw tight and eyes burning with something between fascination and disbelief.
"So… you forged your own path. A new evolution. Hmph." His scowl deepened, but the pride behind it was unmistakable. "Just don't think this puts you above me."
Goku, meanwhile, finally snapped out of his daze.
"So wait, wait, wait—if Super Saiyan was just something all Saiyans could do with enough training…"
He frowned deeply, which was rare for him.
"Then that Legendary Super Saiyan guy—he's real? And he's still out there?"
I nodded once.
Goku looked oddly serious.
"…I wanna fight him."
Everyone face-faulted.
Krillin groaned into his hands.
"Of course. Of course that's where your mind goes."
Piccolo crossed his arms, studying me carefully.
"A mutant bloodline… If what you're saying is true, then your biology itself is different from any Saiyan alive today. Your ki feels different too—more controlled, denser." His eyes narrowed. "How far does this mutation go?"
Before I could answer, Trunks raised a hand eagerly.
"Wait, so you can transform into a giant tiger? Like a real one? How big are we talking?"
Goten immediately sparkled.
"Can we ride it?!"
Vegeta's eye twitched so hard it might've been a seizure.
"NO. Riding a Saiyan transformation is NOT—"
I gently cut in.
"Pretty big. And yes, technically someone could ride it."
Goten and Trunks exploded into cheers.
Vegeta exploded again.
"THAT IS NOT A TOY!"
Bulma grabbed Vegeta's arm. "Oh, hush. If he doesn't mind, let the kids have fun."
Vegeta looked one emotional nudge away from going Super Saiyan himself.
Gohan stepped forward, thoughtful.
"So your base form changed, your biology changed, and your potential changed… Kai, you might actually surpass all of us one day."
I shrugged lightly.
"That's the plan."
The air went still for a heartbeat.
Then Goku stepped toward me, eyes gleaming with excitement.
"Kai… show me. Transform."
The others fell silent. Even Vegeta's breath caught.
This wasn't a challenge out of ego—no anger, no rivalry.
It was pure Saiyan instinct.
Curiosity.
Determination.
Respect.
I smiled, feeling the white-tiger heat simmer beneath my skin.
"Are you sure, Dad?"
He grinned.
"Oh yeah. I wanna see what your new path looks like."
Here we go — continuing smoothly from the last moment, keeping everyone perfectly in-character and building the tension around your new transformation.
The wind shifted.
Not because of power—just anticipation. Every fighter present stood a little straighter, their instincts whispering that something big was about to happen.
I stepped forward.
My tiger tail flicked once behind me, the air tingling as the ground beneath my feet responded to the faint rise in my ki.
Goku tilted his head, watching closely.
"Your energy… it already feels different from before. Wild, but calm at the same time."
Piccolo nodded. "Like a storm hidden inside still water."
Vegeta scoffed. "Tch. Enough poetry. Show us."
I exhaled and let the transformation rise.
Ki flooded through my veins—dense, heavy, alive. A hum filled the air, low at first, then rising into a resonant vibration that made dust lift from the ground. My hair shimmered from white to luminous silver, strands floating upward as if weightless. My eyes shifted from their usual sky blue to a fierce, glowing azure.
Goten gasped. "Woah…!"
Trunks clutched his arms to keep himself from shaking with excitement. "That's so cool…"
Light swirled around me, forming streaks like white flames. My shadow stretched, elongated—becoming the silhouette of a massive tiger before snapping back into my own shape.
The ground cracked under my feet.
BOOM.
A wave of pressure exploded outward—strong enough to make rocks slide across the ground, but controlled enough that no one was pushed back.
Controlled. Refined. Intentional.
Goku's eyes widened. "That's… incredible. It feels totally different from Super Saiyan. It's calm—even when it's strong."
"Of course it is," Vegeta muttered, though his voice carried a hint of disbelief. "That's what a mutation does. It reshapes the base, the foundation… damn it."
Krillin stumbled back a step. "I can barely breathe around this pressure… and he's not even trying!"
Bulma was typing frantically on her capsule device. "These readings… Kai, you're rewriting what we understand about Saiyan biology!"
Gohan grinned softly, admiration glowing in his eyes. "Your energy feels… stable. Like you built this form for yourself, not inherited it."
The transformation settled, my aura pulsing like a heartbeat—steady, powerful, controlled.
I opened my hand, allowing a strand of white ki to coil around my arm like a living ribbon.
Goku breathed out, long and slow.
"…Kai." His grin grew, bright and wild. "That's amazing. But I don't just want to see it…"
He dropped into a stance.
"…I want to feel it.*"
Vegeta shouted instantly, "DAMN IT, KAKAROT, DON'T START A FIGHT HERE—"
Too late.
Goku launched forward.
A burst of wind swallowed the space between us.
And just as his fist neared my cheek—
I caught it.
Cleanly.
Effortlessly. Keep him trapped around my tail.
The shock on his face was priceless.
But even more shocking was Vegeta's expression—pure disbelief, quickly hidden under anger.
"You can't defeat me dad beside this transformation have an amplification to my power level by 20 times". I say releasing him and reverting back to my normal form .
The white light vanished, my hair settling, tail swaying behind me.
But the silence that followed was thick.
Goku didn't move.
He just stared at me—wide-eyed, jaw slightly open, like a kid who'd just been told the universe had ten new levels to explore.
Then—
A slow grin spread across his face, stretching ear to ear.
"Heh… twenty times? And you weren't even using the full twenty just now, were ya?"
I shrugged casually. "im not even using 1% of my full power without trnasnformation."
Goku exhaled sharply, almost laughing in disbelief.
"That's insane…! Son, you've gotten insanly strong."
Vegeta coughed violently, like he'd just swallowed his pride wrong.
"TWENTY TIMES?!"
His voice cracked as he stepped forward, pointing at me like I'd committed a war crime.
"What kind of absurd multiplier is that?! Super Saiyan is only fifty! Super Saiyan 2 is twice that! You're telling me your… your mutant animal form is closing in on Kakarot's transformations?!"
"White tiger form," I corrected politely.
"And yes and what's the bug deal a normale Saiyan ape transformation give them an amlofication of 10 times and according to my study on the transformation ability of us Saiyans
Its goes like this ."
Great ape : 10x Base
SSJ1 /SSJ : 50x Base
SS2: 100x Base
SSJ3: 400x Base
SSS4: 800x Base
"Hold on you studied super Saiyan tranformation ability ? And even managed to surpass super Saiyan 3?"
Vegeta asked shocked .
"Pretty much yeah I call it super
Saiyan 4". I answer with a grin
Krillin whispered to Piccolo, "Is it weird I'm terrified of him even when he's not transformed?"
Piccolo nodded.
"No. That's the correct reaction."
Bulma, instead of being scared, looked like she was witnessing the greatest scientific breakthrough of her life.
"Twenty times… that's unnatural. That's not a biological mutation—that's a complete genetic overhaul. Kai, I need to study your genome. Just a few samples. A hair. A drop of blood. An arm—wait, no, ignore that last one."
I pretended not to hear the last part.
Gohan stepped forward, eyes bright with admiration.
"That level of amplification… Kai, you're not just changing your fighting style. You're rewriting what Saiyans can become."
Goku finally relaxed his stance, rubbing his wrist.
"You're something else, son. But…"
His grin sharpened, turning competitive.
"You saying I can't beat you just makes me wanna train harder."
"Same," I said with a smirk.
Goku's eyes sparkled.
"Hey, we should spar again once I've powered up too! I want to fight you in that tiger form when I'm at my best."
Vegeta scoffed loudly.
"Over my dead body! I'm fighting him next!"
He jabbed a finger at me.
"I refuse to let a cub with fangs get ahead of the Prince of all Saiyans!"
"Sure thing anytime any place". I answer him with a grin. Then stretched my arms behind my head.
"Well, if you guys want to fight me again… you're gonna have to get stronger."
Goku's grin widened.
Vegeta's fury intensified.
Piccolo smirked.
Gohan laughed softly.
The others exchanged nervous looks.
And then Goku said exactly what everyone expected him to say:
"Alright! Training starts NOW!"
Vegeta shouted, "DAMN RIGHT IT DOES!"
I changed my focus to gohan and mom so I
appircahed them and gave each of them a golden credit card. "There you go you two". I say with smile.
"Kai what is this ?".chichi asked confused why would her son give her a credit card. Not showing any fear or being intimidated by his sinsane strength after all he is still her son.
"Yeah brother why give us this?". Gohan asked too following mom steps.
Those credit card conatin infinity money so this will help with the bills and all as for why you also have one brother is because you are not far from starting your own family aren't you . ( I answer with a smile.
I shifted my attention toward Gohan and Mom, walking over with an easy smile. From my pocket, I pulled out two golden credit cards and held them out.
"There you go, you two."
Chi-Chi blinked, confused but not the least bit intimidated by my strength. She was still Mom, after all.
"Kai… what is this?" she asked, eyebrows drawn together. "Why are you giving us credit cards?"
Gohan tilted his head, mirroring her confusion.
"Yeah, bro—what's this for?"
I held back a chuckle.
"These cards contain an unlimited balance. Infinite money. So you won't have to worry about bills, repairs, groceries, Goten's appetite—anything. Ever again."
Chi-Chi froze.
Gohan nearly dropped his card.
"What?!" Chi-Chi almost shrieked. "Unlimited—Kai, you can't just—money doesn't just appear! Where did you even—how—?!"
Before she could spiral, I gently placed a hand on her shoulder.
"Mom, relax. It's legit. No strings attached. Think of it as… your son finally doing something to make your life easier."
Her eyes softened immediately.
"Kai… that's… oh, sweetheart…"
She pulled me into a tight hug, her arms trembling just a little.
"You're such a good boy."
Gohan stared at his card like it was a bomb.
"But… why give me one too?"
I smirked.
"Because you're not far from starting your own family, are you, big brother?"
Gohan's face went crimson.
"M–Mom!" he blurted out.
"he means Videl," Goten yelled from the background.
"GOTEN!!" Gohan hissed.
Goku suddenly appeared behind us, grinning like this was the best drama he'd seen all week.
"Aw, look at you, Gohan! Already thinking about settling down!"
Vegeta scoffed from the side, arms crossed.
"Tch. At least one of Kakarot's brats has common sense."
Gohan covered his face with one hand.
"This is so embarrassing…"
Chi-Chi, meanwhile, was already calculating the future in her head.
"Gohan, this is perfect! You and Videl will have everything you need once you two decide to—"
"MOM!"
I laughed softly as Gohan's entire soul combusted.
But then Gohan took a breath, relaxed, and looked at me sincerely.
"…Thank you, Kai. Seriously. I'll make good use of it. And… I'm proud of you."
Chi-Chi nodded firmly.
"We both are."
Before I could reply—
Bulma jogged over, waving her tablet.
"Wait, hold on—did you say infinite money?! Kai, where exactly is this money coming from? Because unless you found a pocket dimension made of gold—wait, don't tell me you DID—"
I grinned.
"Something like that."
Vegeta muttered under his breath, "This kid gets more ridiculous by the minute…"
Goku, on the other hand?
He just beamed.
"Sooooo… who's getting dinner? Because I feel like celebrating!"
I snaped my fingers retrieving an arc reactor from my inventory showing it aunt Bulma Long with an iron man suite
Bulma's eyes widened the instant the miniature Arc Reactor appeared in your palm—bright, humming softly, impossibly compact.
"What… what is this? The energy readings are insane!" she muttered, already pulling a scanner from her pocket like it was instinct. The device beeped wildly. "This thing outputs more stable energy than half the generators on Earth combined!"
You held out the Iron Man–style armor next. Sleek, crimson and gold, almost vibrating with contained power.
"And this is the suit that runs on it," you added calmly.
Bulma froze. "A full-body exosuit powered by a self-sustaining reactor?" She shot a sharp look at you. "Kai, this technology is decades ahead of what even Capsule Corp can handle."
Vegeta snorted from behind her, arms crossed.
"Hmph. Woman, don't get excited over toys. If the boy wants part of the company, just give him a percentage and be done with it."
Bulma ignored him completely, eyes locked on the armor like it was a new Dragon Ball.
"What percentage?" she asked, voice suddenly business-sharp. "You don't want money, so what exactly do you want out of this deal?"
Gohan stepped close, inspecting the card you'd given him.
"Uh, Kai… infinite money? Is that even allowed?" he murmured, half whispering, half worried.
Chi-Chi, on the other hand, handled her golden card like it was a sacred relic.
"Infinite money? Oh thank you, dear! This will make Gohan's studies so much easier!"
Goku scratched his head. "Bulma, can I try the suit after you?"
"No, Goku!" Bulma and Vegeta yelled at the same time.
Bulma turned back to you, taking a breath to steady herself.
"Alright, Kai. Show me exactly what this reactor can do… and tell me the deal you want. If your tech is real—Capsule Corp will take you very seriously."
She tucked the Arc Reactor under her arm, already itching to test it.
"So," she asked, eyes gleaming with scientist hunger,
"what share are you asking for?"
"5% of capsule crop". I said calmly.
"Deal," Bulma said, and before anyone could blink she had pulled a stack of legal papers out of… honestly, nowhere. Capsule Corp paperwork apparently obeyed its own physics.
You scribbled your name a few times, Bulma stamped something with a flashy CEO seal, and just like that—
You were a billionaire.
Chi-Chi's jaw dropped. Gohan nearly dropped his credit card. Even Vegeta glanced over like he couldn't decide whether to scoff or be impressed.
"Well," you said, linking their cards to your new bank account with a tap on your holo-screen, "if having a monthly income of a few hundred billion zeni isn't infinite money, then I don't know what is."
Chi-Chi swayed like she might faint.
"G-Gohan… we're… rich?"
Gohan blinked. "Uh… Kai… are you sure this is okay?"
"Money is useless to me brother so go ahead " . I say to gohan .
Goku grinned wide. "Hey! Does that mean we can buy more food?"
After that, we made our way to a restaurant and ate until we were completely full. Then Mom went on a shopping spree like there was no tomorrow. After helping her deliver everything back to the house, I slipped away and returned to my personal universe—since that's where I live now.
Time to continue my training.
I know this is just the beginning…
and far stronger opponents are still waiting for me.
