Jupiter's storms had never moved like this.
They had been moving for centuries — the great bands of the planet churning in their slow, enormous patterns, red and white and brown in spirals that took years to complete a single rotation.
Now they moved faster.
Like the planet had read the room.
Like something in the physics of the place had registered what was happening in its shadow and decided to respond in the only way a gas giant knew how — by intensifying, by becoming more of itself, by contributing its particular brand of scale to an already unmanageable situation.
The green dominated the void.
Leo's Atomic aura — the perfected version, the version without the comedy wrapper — filled the space around Jupiter in violent, radiant cyclones. Emerald light on the atmosphere. Lightning arcing between the clouds in colors that didn't belong there.
Neon green.
Void-black.
Blood crimson.
The gravity warped around the aura's edges — space bending, the fabric of what held things in their positions near Jupiter making adjustments it had not been designed to make.
Two figures in the middle of all of it.
---
Argon.
The armor cracked along lines that hadn't been there an hour ago. The cursed runes along its surface pulsed with a light that was trying to hold something together that was under pressure from both directions — from Leo's attacks coming in and from the primal mode coming up from underneath.
His four eyes burned.
Not the void anymore.
Something had come through the void — behind it, underneath it — the thing that the void had been covering.
Fear.
Not large.
Not overwhelming.
But real.
The first genuine thing in those eyes all night.
His chest heaved.
The black lightning around him flickered.
Not the steady crackle of before — the unsteady kind. The kind that belonged to something that was working harder to maintain itself.
Argon: "I have had enough."
His voice through the void.
Through the space.
Through Jupiter's storms.
Argon: "Enough of this."
He looked at Leo across the distance between them.
The pause of a demon king recalculating.
Argon: "You cannot stop me. I am a demon king. That is not a title. That is what I am."
---
Leo floated opposite him.
Feet not quite touching the gas clouds.
The green aura rising around him steady and even — the heartbeat of something that had found its center and was not moving from it.
His hair moved in the solar wind.
His eyes on Argon.
Not rage. Not performance.
Quiet determination — the specific kind that had nothing to prove and didn't need to.
He shifted into stance.
Knees bent. Fists raised. The aura adjusting with him, following the movement the way something follows when it's genuinely part of you rather than something you're carrying.
Leo: "For humanity."
His voice carried across the void the way voices carry in space — not at all, technically, and yet.
Leo: "I will."
Argon's head moved.
No mouth visible.
The malice radiating anyway — through the faceplate, through the void-eyes, through the simple fact of what he was.
Argon: "Then I kill you first."
---
The primal mode arrived not like a decision but like a revelation.
The armor that remained cracking further — not from damage this time but from what was expanding inside it, pressing outward, needing more space than the armor was designed to provide.
The cursed tattoos beneath the fissures flared — alive, pulsing, the marks of every seal that had been placed on what wore them finally having no containment to defer to.
Four arms.
Where there had been two — four. The additional pair emerging with the matter-of-fact quality of something that had always been there and was simply now being used.
Four eyes burning.
The hair rising and moving with the energy passing through it.
The tail lashing.
He looked at his hands.
All four of them.
He cracked his knuckles.
The sound of it reached through the void.
Argon: "Time for my revenge."
He teleported.
---
The punch arrived at Leo's face before the teleport had finished registering.
Leo moved.
Barely.
The wind of the missed punch found him anyway — Jupiter's storms adding their own commentary on the force of it.
Leo countered.
The kick faster than the punch had been, faster than the response window that should have existed.
Argon caught it.
One hand.
One of the four.
The impact between them sent a shockwave outward — not large, relative to the scale of everything around them. But real. Jupiter's cloud banks parting with the pressure of it, the storms nearest them reorganizing around the new variable.
Leo looked at the hand around his leg.
At the ease of it.
His eyes went wide.
Leo: "He caught it."
He said it to himself.
To the fact of it.
Leo: "He caught my technique at that speed."
He pulled free.
Backed off.
Argon: "Is that all you have?"
Cold.
Leo: "No."
He moved again.
---
What Argon did next changed the shape of the fight.
He stopped reacting.
That was the difference — the thing that Leo felt before he understood it, the shift in the exchange that registered as wrong before it registered as specific.
Argon was anticipating.
Not the way something anticipates when it guesses. The way something anticipates when it has seen the pattern enough times to know what comes next before it comes.
Leo's kick.
Argon's block was already in position.
Leo's combination.
Argon's counter was moving before the combination finished.
Leo: "He's adapting."
The thought arrived in the space between dodging and attacking.
Leo: "He's taking my techniques and learning them in real time."
He backed off.
The green eyes brighter.
The specific brightness of someone who has identified a problem and is running through its implications.
Leo: "I will defeat you."
He rushed.
Argon came to meet him.
Four arms — a symphony, the word was accurate, each one moving in its own rhythm that combined with the others into something that covered too many directions simultaneously. Elbows and punches and the angles that came from having twice the number of weapons most things fought with.
Leo moved through it.
Reading the rhythm.
Finding the gaps.
Sliding between the four arms the way water found spaces.
He got through.
His foot found Argon's face.
Clean.
Full commitment.
He landed.
Looked at Argon.
Waited.
Argon turned back slowly.
The faceplate smooth.
The void-eyes.
Argon: "That's all?"
Leo's jaw tightened.
No mark.
No damage.
The kick had been everything he had and it had done nothing visible.
Argon: "Where did your power go, savior?"
---
The two punches to the abdomen came from directions Leo hadn't tracked.
No shockwave from them.
No explosion of force.
They were quiet.
Precise.
The most terrifying kind.
Leo felt them land.
Felt what they did to the inside of him that the outside couldn't see.
His pupils went.
The space before him became the space below him.
He found the gas clouds with his back.
Unconscious before he finished falling.
---
Argon hovered above him.
Looked down.
Argon: "What? Done already?"
The void-eyes reading the unconscious figure below.
Argon: "You were supposed to be a savior."
He let it hang in the air above Jupiter's storms.
Let the irony of it exist in the space between them.
Then —
Fingers.
In the gas clouds.
Clenching.
Leo's fingers finding something to hold even here, even in the formless.
His eyes.
Opening.
The aura — dim, guttering, the transformation trying to keep what it had built.
He felt it fading.
The hair going back to black as the emerald receded.
The green in his eyes going out.
He felt the weight of the planet around him pressing.
He thought about the voice in the gas clouds of Jupiter.
The one that had said his name.
That had called him a miracle.
He thought about Earth.
The size of it from here.
The blue of it.
He snapped his eyes open.
---
He came up through the gas clouds.
Up through the storm layer.
Up into the void between Jupiter and whatever was next.
Argon was above him.
Leo's foot found Argon's cheek.
Everything he had.
The last of the transformation powering the kick, the aura reigniting at the point of contact like it had been waiting for this specific request.
Argon went.
Sideways.
Then down.
The trajectory finding Venus.
Venus received him.
The planet's surface — already volcanic, already under pressure from the forces it dealt with daily — reconsidered its geological arrangements at the point of impact.
Lava spilled at the edges of the new crater.
The fracture lines spreading.
Leo floated.
Breathing.
The transformation steadying as the crisis passed — not full, not back to where it had been at the peak, but holding.
He looked at the Earth.
Still there.
Still blue.
He looked at his hands.
He brought them together.
---
Venus below him.
The green orb forming between his palms — not large, not the size of the domain he'd built around Jupiter. Small.
Contained.
The contained version was the dangerous version.
He felt it pulse against his hands.
The power of it moving outward and then back inward, finding the shape he was giving it, condensing.
Leo: "The Atomic—"
He pushed one hand back.
The shockwave moved through space behind him — not attack, anchor.
He looked at Venus.
At the crater.
At Argon emerging from it.
Leo: "Wave."
---
It came like a decision.
Not an explosion — an extension. The green moving outward from his outstretched palm in a wave that had the specific quality of something that knew where it was going and went there.
Pure.
No smell.
No joke wrapper.
The distilled version of everything Luka Muka Man had always been underneath the performance.
Argon saw it coming.
Raised all four arms.
Built everything he had into the block.
Every piece of the primal mode directed at the incoming force.
The wave consumed it.
The four arms.
The primal mode's output.
All of it.
Consumed.
The wave carried Argon inside it.
Into the light.
Into the green.
Into the silence that lived at the center of the wave where everything had been accounted for.
Leo dropped to one knee.
The knee found Venus's surface.
He was breathing hard.
He was breathing.
Leo: "I saved—"
He looked at the Earth.
Tiny from here.
Whole.
Leo: "Everyone is safe."
The smile came.
Small.
The comedian's smile — not the godlike version, not the hero. The original one.
The one that had been there since before any of this.
Leo: "Everyone is safe now."
---
The hands came from below.
Four of them.
Black.
Emerging from the Venusian surface at the four points of the compass around him.
They found his legs.
His arms.
His shoulders.
Leo: "What—"
The ground exploded.
The force of it was directional — straight up, and then all of it directed at the figure it was holding.
Leo left Venus involuntarily.
Bounced across its surface.
Each impact a separate conversation between his body and the ground.
He drove his hand into the rock.
Stopped.
Looked at the crater he was in.
Looked at what had emerged from Venus's surface.
Argon.
Standing.
The armor — completely destroyed at this point, the pieces of it still present but serving no structural function, just the memory of what they'd been. The cursed tattoos exposed fully, covering everything they'd been beneath the armor. The four eyes open.
The primal mode — not flickering now.
Full.
The full version of what he was without the shell.
Argon: "Youuuu."
His voice shaking the Venusian atmosphere.
---
The beating was specific.
Each punch targeted.
Not the scattered force of something trying to hurt everything — the directed application of black lightning to points that mattered. That the body needed. That it used to keep functioning.
Leo moved through what he could.
He couldn't move through all of it.
The ones that landed landed with the accumulated knowledge Argon had spent the last hour building — the patterns, the responses, the specific ways Leo's body moved when it was trying to protect itself.
He'd given Argon all of that.
Every dodge.
Every technique.
All of it had been information being fed to something that learned.
The final punch.
The mountain behind Leo received the announcement.
He pulled himself out of it.
Rock fell.
Leo: "What are you."
He looked at Argon.
Leo: "What are you really."
He powered up.
The aura coming back.
Slower than before.
Less of it.
He powered up with what he had.
---
Argon teleported.
The kick aimed at Leo's head was the kind of kick that ended things. Leo could see it. Could feel the power in it from the distance it was covering. Could calculate what would happen to the end of this fight if it landed.
Leo closed his eyes.
One breath.
In.
Out.
He felt the kick coming.
He felt the path of it.
He felt the space it wasn't in.
His eyes opened.
He moved.
The kick found air.
Leo: "If strength isn't enough—"
The dark green aura around him changed quality.
Not more powerful.
Faster.
The lightning in it quickening.
Leo: "Then I use something else."
---
Afterimages.
The first one appeared and Leo was already somewhere else.
Then ten.
Twenty.
A hundred — each one a genuine residue of where he'd been, not illusion but the literal trace of his movement through space at a speed that left the image behind before the image knew it was being left.
They moved.
All of them.
In patterns that shared the same quality as the real one — the same aura, the same presence — and none of them distinguishable by sight from where the fight was happening.
Argon's eyes tracked.
All four of them.
Moving between afterimages.
Picking targets.
Argon: "Is this ancient illusion technique?"
He fired.
Black lightning.
Into an afterimage.
The afterimage received it and dissolved and wasn't Leo.
He fired again.
Same result.
And again.
From behind —
The real one.
Leo's foot, smooth, finding the back of Argon's head.
The specific smoothness of someone who has stopped fighting and started moving and found that moving was the language this moment needed.
Argon hit the ground.
The ground of Venus.
Again.
Argon: "THIS ENDS RIGHT NOW!"
He came up swinging.
Leo watched the swing arrive.
Leo: "Too slow."
Not unkindly.
As a fact.
Three punches.
The combination that Leo had been calculating since the moment he identified agility as the solution. The three points — head, chest, abdomen — that he'd mapped precisely by watching Argon fight for the last hour.
Head.
Chest.
Abdomen.
Each one landing with the whole of his speed behind it.
Argon went backward through the air of Venus.
Leo was already in front of him.
The kick from the front finding the head.
Argon continued.
Planet to planet.
The trajectory carrying him until Uranus received him.
The planet accepted him with the specific grace of something very large encountering something very fast.
Leo stood in the space between.
Breathing.
Waiting.
---
Uranus settled.
Argon stood on it.
Bloody.
The primal mode holding but at cost now.
He looked at Leo across the void.
And something happened in his expression — behind the void-eyes, behind the faceplate — something moved.
The thing Leo had seen earlier, when the domain first closed around him.
But different now.
The fear was still there.
Underneath it — something else.
The specific calculation of a thing that has decided it has lost and is working through what to do about that.
He started laughing.
Low first.
Then not low.
The laugh echoing through the void the way his voice had echoed in Tokyo — through everything, reaching everything.
Leo: "..."
He looked at Argon.
Leo: "What's wrong with you."
The laugh didn't answer immediately.
When it stopped —
The silence it left was the worst silence of the night.
Argon's voice.
Quiet.
Conversational.
The specific quiet of someone who has arrived at the part of the conversation they've been building toward.
Argon: "You think you can defeat me."
He tilted his head.
Argon: "Yes. You can."
He let that sit.
Argon: "But I will take everything with me."
Leo: "What do you mean."
Argon: "The timer started when you landed the first hit."
Leo: "What timer."
Argon held up one finger.
The black lightning around that finger coalesced.
The specific coalescing of something that had been building for a while and was now being shown.
Argon: "Ten minutes."
A pause.
The void.
The stars.
Earth below them — blue, small, unaware.
Argon: "Then I explode."
Another pause.
Argon: "Galaxy level."
Leo's eyes.
They went wide.
Not the shock of a fight.
The shock of a problem that couldn't be solved the way the last hour had been solved.
You couldn't punch an explosion.
You couldn't dodge it.
You couldn't be faster than it.
Leo: "No way."
His voice.
The godlike calm of the perfected Atomic Awakening gone.
Just the voice underneath.
Just Leo.
Just the person who had been carrying this city, this planet, everything —
Staring at a clock he couldn't see ticking down to something he couldn't stop.
Argon smiled.
Somewhere behind the faceplate.
The cosmos waited.
Silent.
Breathless.
Ten minutes.
