MARVEL/DC: DOCTOR IN THE MULTIVERSE

The instant Lynn's arm pierced through the Tesseract barrier—

The entire rooftop energy apparatus destabilized violently.

SKRRRRRREEEE—!!!

The enormous azure beam connecting Earth and deep space twisted uncontrollably beneath the forced interference.

Energy fragments erupted wildly from the collapsing system.

Several supporting steel pillars surrounding the platform melted instantly under spatial-energy overload.

The structure of Stark Tower groaned like a living creature under catastrophic stress.

But Lynn remained unmoving.

His hand finally touched the Cosmic Cube itself.

Cool.

Perfectly smooth.

The instant contact occurred—

Analysis of All Things activated at maximum capacity.

Infinite spatial data poured into his consciousness like a collapsing galaxy.

The internal structure of the Tesseract exceeded even his expectations.

Each face of the cube functioned as an independent spatial-folding layer.

Six surfaces.

Six dimensions of folded space.

Interlocked into a perfect topological closed loop.

An artifact bordering conceptual-level existence itself.

But now was not the time for research.

Lynn tightened his grip.

Then—

He pulled.

Boom—!!!

The Tesseract was physically ripped free from the energy device.

The moment the energy supply disconnected—

The gigantic beam piercing the heavens flickered violently several times.

Then collapsed.

Starting from the rooftop base—

The azure pillar shattered apart segment by segment like a skyscraper losing its foundation.

Above Manhattan—

The gigantic wormhole began shrinking rapidly.

The dimensional tear groaned violently while folding inward.

Countless Chitauri troops still attempting retreat were caught inside the collapsing spatial rift.

Then crushed.

Their bodies fragmented into glowing particles before dissipating into the atmosphere completely.

Farther away—

The four retreating Leviathans accelerated desperately toward the shrinking portal.

Two escaped successfully.

The remaining two were slower by less than half a second.

The closing wormhole severed them directly in half.

Boom—!!!

Gigantic bisected corpses fell from the upper atmosphere into the surrounding Hudson and East Rivers.

Towering tidal waves erupted outward upon impact.

Meanwhile—

Every remaining Chitauri soldier throughout New York froze simultaneously.

Their weapons powered down instantly.

Armor lights vanished.

Then—

Like puppets whose strings had been cut—

The alien infantry collapsed lifelessly across the battlefield.

Inside battlefield communications—

Captain America's voice trembled faintly.

"The wormhole…"

"…it's closed."

No one answered.

Because at that exact moment—

Every functioning satellite.

Every military reconnaissance system.

Every surviving news drone on Earth—

Focused on one location only.

The top of Stark Tower.

There—

A black-clothed figure wearing a blank white mask stood motionless at the city's highest point.

In his left hand—

The defeated invader commander:

Loki.

In his right—

The glowing blue Tesseract itself.

Behind him—

The smoke of war drifted across New York's skyline.

Below him—

A city had just been saved.

The entire world watched silently.

Lynn ignored all of it.

Analysis of All Things had already identified rapidly approaching targets.

Approximate arrival time:

Twelve seconds.

Thor's hammer cutting through the atmosphere.

Iron Man's damaged thrusters approaching at maximum remaining output.

And inside the tower stairwell—

Steve Rogers' heavy but determined footsteps.

Lynn casually tossed the Tesseract upward once in his hand.

This artifact could not be taken.

Not because he lacked the power.

But because "the masked figure stealing the Tesseract" would instantly make him the highest-priority target of both Earth and Asgard simultaneously.

Pointless.

He set the Tesseract calmly beside the damaged energy apparatus.

Then casually dropped Loki nearby like discarded trash.

Just before leaving—

Lynn paused briefly.

His gaze lowered toward Loki automatically.

Analysis of All Things scanned instantly.

Internal neural backlash.

Minor rib fractures.

Cervical soft-tissue damage.

Nothing fatal.

No treatment opportunity.

No copy value.

And anything worth copying from Loki—

Illusion magic.

Mental interference.

Soul deception—

Had already been analyzed during their first encounter.

Now—

Loki's talents held no further meaning to Lynn.

Then—

Golden lightning exploded downward from the clouds.

Boom—!!!

Thor Odinson landed heavily upon the opposite side of the rooftop.

His armor looked badly damaged.

Cape partially burned away.

Mjolnir crackled with storm energy inside his grip.

Fury burned visibly across his face after escaping Loki's trap moments earlier.

Immediately afterward—

Iron Man descended from the sky trailing smoke.

The Mark VII armor landed unevenly.

The chest reactor flickered intermittently from severe power depletion.

Finally—

Captain America burst from the rooftop stairwell breathing heavily.

Fresh blood still seeped faintly through his recently repaired chest bandages.

Yet Steve Rogers immediately raised the vibranium shield instinctively.

The three heroes spread outward gradually.

Forming a loose encirclement around the masked figure.

Thor spoke first.

His voice rolled across the rooftop like thunder itself.

"Did you close the wormhole?"

The masked figure did not answer immediately.

Instead—

Thor's gaze shifted sharply toward the Tesseract.

Then toward Loki collapsed nearby.

"Hand over the cube…"

Thor's grip tightened around Mjolnir.

"…and release my brother."

Anger existed inside his voice.

But also caution.

Because Thor himself had witnessed the Leviathan being destroyed barehanded earlier.

Behind the mask—

Lynn smiled faintly.

Then—

Without warning—

He tossed the Tesseract casually toward Thor.

The glowing blue cube crossed the rooftop rapidly.

Not heavily thrown.

But absurdly fast.

Fast enough that even Thor instinctively caught it using both hands.

Bang.

The impact forced the God of Thunder backward half a step.

Thor lowered his eyes toward the Cosmic Cube.

Then looked up again slowly.

"Control your toys properly, Asgardian."

The cold mechanical voice echoed beneath the white mask.

Thor's brow furrowed instantly.

"Who exactly are you…?"

Beside him—

Tony Stark retracted the damaged faceplate halfway.

Dust and sweat covered his exhausted face.

But his eyes remained locked on the masked figure intensely.

Because Tony had realized something crucial.

This man returned the Tesseract willingly.

And with the power he had demonstrated—

No one present could have stopped him from taking it.

Meaning only two possibilities existed.

Either—

He simply did not care about an Infinity-level artifact.

Or—

He possessed goals far beyond the Tesseract itself.
