The X-Men (The O5) | Danger Room

The hallway was burning exactly as you remembered it. Flames crawled across the ceiling in long orange sheets. Smoke rolled thick along the upper walls, swallowing exit signs and turning every doorway into a blackened mouth. Somewhere farther down the corridor, glass shattered beneath the pressure of another distant explosion.

The floor groaned beneath you. For several seconds, nothing moved except you and the fire. Then a voice came softly through the earpiece.

"Take your time." Hank's voice; his words were almost unnervingly calm against the roar around you. "You are not being timed. For now, I simply want you to familiarize yourself with the environment."

Another section of ceiling cracked overhead.

"You've seen this place before," Scott added. "Use that."

The corridor opened toward the stairwell ahead, its walls already split by heat.

Everything was there. The scorched wallpaper. The apartment doors. The broken light fixture hanging at an angle. Even the smoke seemed to move the way it had that night. Almost too perfectly.

But beyond the burning apartment building, where the simulation ended against the enormous metallic walls, Hank stood beside its controls with Scott and Jean nearby. From the observation room outside the chamber, Charles watched the exercise through reinforced glass.

None of them could be seen from where you stood. Here, there was only the fire, the night sky outside, and parts of the recognizable city.

Scott's voice followed through the receiver. "Don't let the reconstruction distract you. You already survived this once."

Jean glanced toward him from outside the simulation. "Very comforting."

"I'm reminding {{obj}} of a fact."

There was a brief silence until Hank cleared his throat. "Moving onward."

The flames reflected across the smoke ahead.

"The reconstruction was assembled from emergency photographs, structural reports, surviving footage, and your building's original plans. Once you're comfortable with the environment, we begin the actual exercise."

A ceiling fixture crashed several feet away, showering sparks across the floor. "Treat this as though the fire were happening again," Hank continued. "Use whatever abilities you ordinarily possess. Whatever you would naturally have attempted that night before the unexplained energy manifestation occurred."

Outside the structure, Hank's attention remained fixed on the readings. "For now, the objective is straightforward: contain the fire, stabilize the building, escape—whatever solution your mutation allows."

"No." Scott's interruption came instantly.

Hank looked sideways. "No?"

"That's not what happened." Scott stepped closer to the simulation boundary, watching the burning structure. "{{user}} wasn't trying to save a building."

Jean understood first. "Scott."

"There were people inside."

"You're trying to establish a baseline, not recreate the trauma."

"I'm trying to establish the circumstances."

Scott's voice entered your earpiece again. "If this is supposed to tell us what you did differently that night, then the problem needs to be the same."

Somewhere above you—

"HELP!"

The scream ripped through the hallway.

Another voice answered from behind one of the apartment doors. "Is anybody there?!"

Footsteps suddenly pounded across the floor overhead. A child began crying somewhere deeper inside the building. They hadn't been there a second ago.

Hank stared at Scott. "You added occupants."

"Rescue targets."

Jean folded her arms. "You could have warned {{user}}."

Scott remained focused on the simulation. "Last time I didn't."

Another violent crack traveled through the walls. The corridor ahead buckled slightly.

Hank exhaled. "Very well."

Hank's voice returned through your receiver. "Simulated residents are now distributed throughout the building. Their locations are unknown to you and will respond dynamically to the fire. Structural stability, smoke density, blocked routes, and heat will progressively worsen."

Jean leaned slightly toward the microphone. "If you need us to stop, say it. Immediately."

Scott followed. "Don't recreate what you did."

Another scream echoed from above.

"Recreate the problem."

Fire surged across the hallway ahead.

"Find the people. Get them out. And when something gets in your way—"

A support beam split with a deafening crack.

"—show us what you normally do about it."

Outside, Hank's hand settled over the controls. "Full simulation beginning."

The apartment building groaned around you. Somewhere behind the smoke, someone shouted for help again.

And finally, Scott's voice sharpened in your ear. "Go."

The fire had stopped feeling like a simulation long ago. The heat rolled through the corridor in violent waves. Smoke had thickened enough to turn the far end of the hallway into a black blur, while flames tore through doorframes and climbed along the ceiling faster than they had during the first few minutes.

Still, you kept moving.

One trapped resident was guided toward a stairwell. Then another. A blocked doorway was forced open. A collapsing section of wall gave way just after several others cleared it.

From outside the reconstructed building, Hank watched the readings scroll across his monitors.

"Still consistent."

Scott's attention stayed fixed on the simulation. "Nothing?"

"Nothing beyond {{poss}} established mutation."

Jean glanced toward the burning structure. "So whatever happened during the real fire still hasn't happened."

"Precisely."

Scott said nothing.

Then one of the simulation parameters changed.

Hank looked down. "Scott."

"Increase structural failure by twelve percent."

"You might have mentioned that first."

"We're still inside the safety threshold."

"That's not really the point." Jean's expression tightened.

Scott didn't look away. "If pressure triggered it before, then comfort isn't going to teach us anything."

Inside, the building answered almost immediately. A violent explosion ripped through the wall beside you. The blast hit hard enough to tear you away from the group you had been guiding, throwing you across the corridor as fire and fragments burst through the air.

You struck the floor, and for several seconds everything rang.

Outside, Jean stepped forward. "Scott."

"Wait."

Hank's hands hovered over the controls. "Impact registered. No serious injury."

Inside the simulation, the residents scattered toward the stairwell while the corridor groaned around you. The wall nearest you had partially collapsed. Then the ceiling began to follow. Chunks of plaster and concrete broke loose overhead.

"{{user}}, can you hear me?" Jean's voice entered your earpiece.

Another section crashed down nearby.

"If you need us to stop—"

"Give {{obj}} a second," Scott said.

Hank looked sharply toward him.

Above you, something enormous shifted. A support section, weakened by the explosion, tore free, and the wreckage dropped at furious speeds. There was nowhere left to move. Your arms came up instinctively.

And—

impact.

Except nothing touched you. A translucent layer of energy had erupted overhead. It wasn't smooth. Light trembled violently across its surface as several tons of debris slammed into it, sending ripples through the barrier like cracks spreading across glass.

But it held.

Outside, every monitor changed at once.

"Wait." Hank froze, watching numerous lines of data surge across the display.

Scott stepped closer. "What?"

"That."

Jean turned toward him.

"What am I looking at?"

"Not the same thing." Hank's earlier calm vanished beneath sudden concentration. "The readings we've recorded throughout the exercise have remained consistent with {{poss}} primary X-gene expression." Another spike crossed the screen. "This is separate."

Scott's head lifted immediately. "Separate how?"

"I don't know yet."

Jean stared toward the buried section of hallway. "You mean that shield isn't part of {{poss}} mutation?"

Hank shook his head slowly. "I mean it isn't the mutation we've been measuring."

Behind the reinforced observation glass outside the Danger Room, Charles leaned forward in his wheelchair.

Back inside the building, the barrier above you flickered again. The debris shifted, then fell aside as the strange energy finally collapsed.

Jean exhaled.

Scott did not. "There." Hank glanced toward him. "That was what we were looking for. That's what happened in the building."

The simulated structure groaned again. This time, not just one corridor. Somewhere below you, windows exploded outward. Another floor partially collapsed. Emergency lights failed across several levels. Fresh voices began calling through the smoke from opposite ends of the building.

Hank's eyes widened slightly as he checked the controls. "Scott."

"We know it can happen."

"That does not mean—"

"We still don't know why."

"And your solution is to make the entire building worse?" Jean folded her arms.

Scott's expression remained fixed on the simulation. "My solution is to find out whether that manifestation was an accident."

Inside, the wreckage around you shifted enough to leave the corridor open again. The last traces of the shield faded from the air. But ahead, the fire had spread. And behind you, another scream echoed from a different floor.

Hank reluctantly returned his attention to the controls. "Structural failure is now building-wide. Multiple rescue targets. Independent fire progression across every level."

Jean leaned toward the microphone. "Don't chase the shield, {{user}}. Just keep moving."

Scott followed a moment later. "Do what you were doing before."

Another explosion shook the building.

"Let's see if it happens again."

The building had become something worse than memory. The smoke no longer gathered only along the ceiling; it swallowed entire corridors now, thick enough to turn distant flames into dull orange smears.

Scorching heat pressed through every wall. Windows burst without warning. Fire spread where nothing had been burning seconds earlier, fed by ruptured pipes, collapsing rooms, and the simulation's relentless attempts to keep pace with you. Somewhere beneath it all, the structure kept groaning.

But outside the reconstruction, Hank's monitors were beginning to struggle to separate one emergency from another.

"Structural failure across several levels," He said as his eyes moved rapidly across the data. "Fire progression has exceeded the original reconstruction."

Scott barely moved. "It's adapting."

"Quite aggressively."

Another warning flashed.

"Huh?"

Scott looked beside him. Empty. Then his head snapped toward the simulation.

"Jean."

She was already moving, crossing the open floor within the Danger Room at a run. Her telekinesis caught her at every stride, launching her farther than momentum alone should have carried her.

She cleared one simulated vehicle, vaulted another stretch of ruined pavement, and rose outright for the final distance toward the burning building.

"Jean, don't enter," Scott warned through the comm.

"The simulation is calibrating around {{user}}," Hank added. "If it recognizes your abilities as an active variable—"

"I know." She never slowed.

Jean lifted one hand, tearing out a collapsed section of exterior wall beneath a red-gold shimmer, opening a path just long enough for her to disappear through it.

Scott stared after her.

"And now it has two Mutants to compensate for." Hank exhaled.

---

Inside, visibility was nearly nonexistent. Jean landed hard among shattered concrete, immediately raising a telekinetic barrier as burning debris rained down around her.

"{{user}}?"

Only the fire answered. She pushed onward. One blocked corridor peeled apart before her. Another required an entire collapsed doorway to be dragged sideways through the smoke. The farther she moved, the harder the building fought back.

Jean brought two fingers to her temple, narrowing her eyes to hundreds of impressions crashing against her awareness at once—simulated panic, movement, screaming voices, overlapping distress.

She reached farther. And suddenly—clarity.

Jean froze.

"There."

Your mind stood out through the chaos with startling precision, almost too easily even for a simulation.

For half a second, confusion crossed her face, but another explosion shook the floor and forced her on the move.

---

You were still moving survivors when her voice reached you. Not through the receiver, but inside your head.

{{user}}?

The contact was unmistakable—clearer than any voice fighting through the fire around you.

It's Jean. I'm inside.

A section of corridor collapsed somewhere ahead.

Keep moving. I'm coming to you.

Minutes blurred into the smoke and impact. But Jean eventually emerged through a torn-open passage, one hand raised as debris twisted away from her path. Whatever argument Scott had expected from her never came.

She simply saw the remaining survivors with you and helped. Her telekinesis ripped open blocked exits. Falling beams stopped long enough for people to pass beneath them. You continued pushing forward beside her while the simulation escalated around both of you.

"Two remaining!" Hank warned through the comm.

Jean held a fractured stairwell in place. "Then let's finish it."

---

The final rescue targets cleared the lower corridor. However, the building started failing. Not one room, not one ceiling, but a massive portion of the upper structure tore loose above you both.

"Oh, you've got to be kidding me."

Jean looked up, shooting both hands upward and stopping the total collapse, barely. Concrete, steel, flaming walls—an entire section of the building hung above you beneath the violent shimmer of Jean's telekinesis.

Her knees bent. Her jaw tightened as strained groaning escaped her. The weight pressed lower and stronger against her.

"Jean—" Outside, Hank shot forward.

Then the monitors surged. The second signal erupted across the readings around you. The strange, secondary energy flared around you.

Jean's eyes widened. The excruciating strain changed. Her telekinetic field suddenly expanded through the wreckage with a force that startled even her.

The crushing mass stopped descending. Slowly, it rose. Jean stared upward for one stunned heartbeat, before shouting and throwing the massive section away.

The entire collapsed section ripped free and sailed across the simulated skyline, smashing through two empty reconstructed buildings in a thunderous avalanche of steel and concrete.

Jean looked at her own hands, panting to catch her breath. "That was..."

Hank killed the simulation instantly. The fire vanished, smoke disappeared. The ruined city dissolved into light, leaving nothing but the vast metallic chamber around you.

Jean's telekinesis faded. And across the floor, Hank was already approaching with Scott beside him.

Scott's attention moved from the vanished wreckage to Jean. "You alright?"

"Yeah." She looked toward you. "I think."

Hank reached you all with the tablet already alive with overlapping graphs. "Jean." She glanced down. "When you caught that collapse—how hard were you pushing?"

"Very." A pause. "... at first."

Scott looked at Hank.

Hank turned the display toward you all. "Your telekinetic output increased at precisely the same moment {{user}}'s secondary signature manifested again."

Jean's expression changed. "You think {{sub}} did that?"

"I think," Hank said carefully, "that whatever this second phenomenon is... it may not affect only {{obj}}."

Scott stared at the two rising lines on the screen. For once, though, he didn't argue.
