Super Saiyan Four

The Hyperbolic Time Chamber door closes behind us with a heavy thud. White emptiness stretches in all directions, broken only by the small living quarters near the entrance. We need space for what's about to happen.

"This way," I say, pointing to the distant horizon. "We need to be far from the entrance."

We fly in silence for several minutes until the entrance building looks like a tiny speck behind us. The emptiness here feels appropriate for unleashing primal Saiyan power.

"Here will work," I say, touching down on the white surface. "Goku, you'll go first."

Goku nods, his normally carefree expression replaced with unusual seriousness. His tail sways behind him, responding to his heightened focus.

"Stand over there," I direct, pointing to a spot about fifty meters away. "Remember, focus on maintaining your consciousness when the transformation begins."

Vegeta and I take position at a safe distance. I raise my palm upward, gathering energy into a concentrated sphere.

The white ki ball pulses with artificial Blutz Waves - the same energy reflected by the full moon that triggers the Oozaru transformation.

"Ready?" I call to Goku.

He nods firmly. "Ready."

With a quick motion, I launch the Power Ball high above us. It hangs in the white void, glowing intensely.

"Look at it now, Goku. Remember - fight to stay conscious."

Goku tilts his head up, eyes fixed on the artificial moon. For a moment, nothing happens.

Then his eyes widen and turn red as the Blutz Waves take effect. His body tenses, tail stiffening behind him.

A low growl escapes his throat as the transformation begins. His muscles swell, stretching his armour.

Brown fur sprouts across his expanding body.

His face elongates into a muzzle filled with sharp fangs. Within seconds, a massive Oozaru stands where Goku had been - a giant ape-like creature towering nearly fifty feet tall.

The beast roars, the sound echoing through the endless chamber. I tense, ready to intervene if Goku has lost control to the primal instincts of the form.

The Oozaru goes still, its massive chest heaving with deep breaths. Then it looks down at its hands, turning them over slowly.

"I think he's maintained consciousness," Vegeta says beside me.

The giant ape turns its head toward us. Red eyes focus with clear intelligence.

"This... is... amazing!" The voice is deep and rumbling, but unmistakably Goku's. "So... much... power!"

Relief washes through me. "You're in control?"

The Oozaru nods its massive head. "Yes... hard to... think clearly. Instincts... strong."

It seems because Goku wasn't in an as emotionally draining situation like he was against Baby, he wasn't out of control.

"Focus," Vegeta calls out. "You are a warrior, not a beast. Control it."

For the next hour, we guide Goku through increasingly complex movements. His control improves steadily - speech becoming clearer, movements more precise.

The red eyes still burn with primal energy, but Goku's consciousness clearly dominates.

"He's ready for the next phase," I say to Vegeta, who nods in agreement.

"Goku," I call up to the massive form. "Now try to channel Super Saiyan energy through the Oozaru form."

The giant ape tilts its head. "How?"

"The same way you normally transform," I explain. "Focus on that feeling, that trigger. Just channel it through this form instead."

The Oozaru closes its eyes in concentration. At first, nothing happens. Then golden light begins to flicker around the massive body. Patches of brown fur start turning gold, the transformation spreading gradually across the giant form.

The chamber trembles as power surges through the transforming Oozaru. The golden aura intensifies until it envelops the entire body.

Within moments, a Golden Oozaru stands before us, radiating power that dwarfs even his Super Saiyan 3.

"The power... incredible," the golden beast rumbles, its voice clearer than before.

"Now for the final step," I call out. "Like we theorised, compress that power. Draw it inward while maintaining its intensity. Make it more efficient."

The Golden Oozaru nods and closes its eyes again. For several minutes, nothing visible happens. Then the massive form begins to shimmer, golden light pulsing rhythmically around it.

Suddenly, blinding light erupts from the giant body. The chamber shakes violently. When the light fades, a transformed Goku stands where the Golden Oozaru had been.

Red fur covers his torso and arms. His hair has lengthened and turned black again, wilder than before. His eyes become gold but now have black pupils. His tail has turned red to match the fur on his body.

The power radiating from him is astonishing - far beyond Super Saiyan 3, yet perfectly controlled.

"Goku?" I approach cautiously. "How do you feel?"

He examines his transformed body with wonder. "Incredible," he says, his voice deeper than normal. "The power is amazing, and my mind feels so clear - no struggle for control at all. I feel like I can finally take you on in your base form.

If I had this against Buu then we would've never needed to fuse!"

"Super Saiyan 4," I state the name of the transformation. "The true evolution of Saiyan potential."

Goku moves through several combat stances, testing his new form. Each movement flows with perfect precision, carrying devastating power yet showing complete control.

"Your turn, Vegeta," Goku says with a grin.

Vegeta steps forward, eager despite his attempt to appear composed. I reinforce the Power Ball with fresh energy as Vegeta takes position.

His transformation progresses more quickly than Goku's. The Oozaru form comes with practiced ease, clearly showing his prior experience.

When he shifts to Golden Oozaru, the transition is seamless, controlled.

The compression to Super Saiyan 4 follows the same pattern - blinding light, then the emergence of the more compact form. Vegeta stands transformed, red fur covering his upper body, his flame-shaped hair longer and wilder, eyes teal with black pupils.

"Impressive," he says, examining his new form. "The power is extraordinary."

Now it's my turn. I move to the position they vacated, both of them watching from a safe distance in their Super Saiyan 4 forms.

Looking directly at the Power Ball, I feel the change begin immediately. My vision turns red as the Blutz Waves take effect. Primal energy surges through me as my body expands rapidly.

Within moments, I tower above the chamber's white plain as an Oozaru larger than either Goku's or Vegeta's had been.

Despite the primal instincts flooding my consciousness, my mind remains clear and focused.

The transition to Golden Oozaru comes naturally, golden light washing over my massive form.

The chamber's very fabric seems to strain under the pressure of my power, the white void flickering momentarily.

"Careful!" Goku shouts from below. "The chamber can't take too much!"

I modulate my energy output, stabilizing the transformation while minimizing environmental strain. Then I focus on the final phase - compressing this enormous power into a more efficient form.

Drawing the energy inward, I feel my massive body begin to contract. The power concentrates rather than diminishes, becoming more focused with each passing second.

Blinding golden light erupts around me. When it fades, I stand in my Super Saiyan 4 form - similar to Goku's and Vegeta's, but with notable differences.

My fur is darker crimson, my hair longer and wilder while maintaining my distinctive style, my tail thicker and longer.

The power flowing through me surpasses anything I've experienced before - a level that makes even my base form seem limited by comparison.

"Incredible," Vegeta says, genuine awe in his voice. "Your power is beyond comprehension."

I test my new form with simple movements. Each motion creates shockwaves in the chamber's atmosphere despite my careful control.

Unlike normal Super Saiyan 3, there's no energy drain - this form feels sustainable indefinitely.

"We should return to the entrance," I suggest after several minutes. "We've pushed the chamber far enough for one day."

We fly back toward the entrance, the journey taking an instant in our transformed state. As we approach the living quarters, I consider what we've achieved.

Super Saiyan 4 represents more than just increased power - it's a return to something essential in Saiyan nature, something lost when our tails were removed. This form feels right, balanced, complete.

For Goku and Vegeta, its akin to them having fused - that's how big of a jump in power this form is.

But for me who is already a fusion, my power multiplied as if I fused with myself - can I handle Beerus like this?

Which Beerus is it even? The Super one seemed far more powerful than the Z movie one.

Damn it all, these timelines make everything so confusing.

At least - I for sure know now that there is no Daima, for this form of SSJ4 is not the Daima version.

"We should practice returning to base form before we exit," I tell the others.

Goku demonstrates first, the red fur fading away as his hair returns to normal. "That was easier than I expected," he comments. "It feels natural, not forced like Super Saiyan 3."

Vegeta reverts next, the transformation receding with his characteristic precision. I follow suit, drawing the power inward until I return to base form, my tail once again brown and wrapped around my waist.

"A successful experiment," I observe. "We've unlocked a transformation that changes everything."

We exit the Time Chamber to find Dende and Mr. Popo waiting anxiously. Relief washes over their faces when they see us emerge unharmed.

"You succeeded?" Dende asks, studying our appearances carefully.

"Beyond our expectations," I confirm, my tail swishing behind me with newfound awareness. "The transformation worked perfectly for all three of us."

"I sensed incredible power fluctuations," Dende says. "Even from outside the chamber, the energy was... overwhelming."

"You should have seen it!" Goku exclaims, his excitement bubbling over. "First we turned into giant apes, then golden apes, and then-" he makes an explosive gesture with his hands, "-we compressed all that power into this amazing new form!"

"Super Saiyan 4," Vegeta states with unusual satisfaction. "A transformation that draws on our true Saiyan heritage."

Mr. Popo steps forward, offering refreshments. "The chamber appears to have withstood your training, though I detected some dimensional instability."

"We were careful," I assure him, accepting a drink. "Though Vegito's transformation pushed the boundaries of what the chamber could handle."

"His power in the new form is something else entirely," Goku adds, grabbing several pieces of fruit from the offered tray. "Makes me wonder what would happen if we fused while both in Super Saiyan 4."

Vegeta scoffs. "Let's not get carried away, Kakarot. We've only just mastered this transformation."

"We should demonstrate the form to the others," I suggest. "But in a controlled setting, away from populated areas."

"The wasteland where we first fought Cell would work," Goku offers. "Plenty of space, no people around."

"Agreed," Vegeta nods. "We should also test the combat capabilities of this form through sparring."

"I'll contact everyone," Dende volunteers. "When would you like to meet?"

"Tomorrow," I decide. "We should rest and process what we've experienced today."

As we prepare to leave the Lookout, I notice Vegeta studying his tail with a thoughtful expression.

"Something on your mind?" I ask him quietly while Goku chatters with Dende about the transformation.

"This form," Vegeta replies, his voice uncharacteristically reflective. "It feels right in a way the other Super Saiyan transformations never did. As if we've rediscovered something essential that was lost."

I nod in understanding. "It brings balance - the primal power of our Oozaru heritage with the focused control of Super Saiyan."

"Gohan should learn this transformation," Vegeta says unexpectedly. "He was born with a tail, after all. The potential is there."

The suggestion surprises me. "I thought you might consider this form exclusive to full-blooded Saiyans."

Vegeta shrugs. "Power is power. Gohan has proven his Saiyan heritage many times over. Besides," a slight smirk crosses his face, "it would be satisfying to see Kakarot's son surpass him again."

Our conversation is interrupted as Goku bounds over. "Ready to head back? Chi-Chi's probably wondering where I've been all day!"

"Go ahead," I tell them. "I want a moment to speak with Dende."

After Goku and Vegeta depart, I approach the young Namekian guardian. "There's something I need to ask you."

"About the new transformation?" Dende inquires.

"No. About something else entirely." I lower my voice, though we're alone on the Lookout platform. "Have you sensed any... unusual cosmic energies lately? Anything that might suggest powerful beings taking an interest in Earth?"

Dende's expression turns serious. "Nothing specific, but there have been... disturbances in the cosmic balance. Subtle shifts that I can't quite identify." He studies me carefully. "You know something, don't you?"

I choose my words carefully. "Let's just say I have reason to believe Earth may face new challenges in the coming months. Challenges that might require even the power of Super Saiyan 4 to address."

"I see," Dende says, though his expression suggests he has more questions. "I'll remain vigilant and inform you of any unusual cosmic activity."

"Thank you," I reply. "And one more thing - we should consider restoring Gohan's tail. If my theory about Super Saiyan 4 is correct, he should be capable of achieving it as well."

Dende nods thoughtfully. "That would require another wish from the Namekian Dragon Balls. I can communicate with my people to arrange it, if you think it necessary."

"I do," I confirm. "The more warriors capable of reaching this level, the better prepared we'll be."

With our discussion concluded, I take to the sky, heading back toward West City. The sunset paints the landscape in golden hues as I fly, my tail providing subtle balance adjustments that feel increasingly natural.

My mind turns to the implications of what we've achieved today.

Super Saiyan 4 represents a power level I hadn't dared hope for - especially my own version of the transformation, having been worried it was wishful thinking, but no, thankfully it was not. 

If Beerus arrives as he did in the timeline I remember, we might actually stand a chance against him now.

Not just to survive his visit, but potentially to earn his respect from a position of comparable power rather than desperate inferiority.

In the end Super Saiyan 4 changes everything. Especially if it is exactly as in GT - for this form adapts.

Once something is used against it and survived, it will no longer work against it - a great boon anymore.

Besides this it can be maintained even in the weakest of states - even when almost completely drained to the point even glass can harm you - the form still remains.

Though its greatest boon is its ability to negate the power of the Black Star Dragon's wish - which may if one is powerful enough even be able to protect one from such a wish.

The Black Star Dragon is the same Dragon who was said to be able to do quite literally anything - if this is true then I need not worry about Zamasu.

But I can't be sure. I need to take the necessary precautions.

As Capsule Corporation comes into view, I make a decision. Tomorrow's demonstration will be more than just showing off our new transformation.

It will be the beginning of a new training regimen - one designed to master Super Saiyan 4's capabilities and prepare for whatever lays ahead.

I will not be a pawn in this game of life.
