The reactor room was bathed in darkness, the only source of light coming from Saitama's fiery fusion with Magmate. His body glowed with an intense heat that illuminated the swirling shadows, creating an eerie contrast against the void of space.
Across the room, the Shadowmaster hovered, its form a twisted amalgamation of black smoke and flickering darkness. Its glowing red eyes bore into Saitama, promising death and destruction.
---
[Warning: The Shadowmaster has entered its final phase. Its power is now at maximum.]
---
Saitama clenched his molten fists, feeling the immense power of his new **Magmate Fusion** coursing through him. It was overwhelming, the heat burning in his veins like liquid fire. But he could control it—channel it into something far greater.
"I didn't come this far to lose," Saitama muttered under his breath, his eyes narrowing on the Shadowmaster.
Magmate's voice echoed in his mind, a low, rumbling growl of approval. Together, they were stronger—together, they could end this.
The Shadowmaster's laughter filled the reactor room, a chilling sound that reverberated through the metal walls. "You think your fire can stop me? I am the darkness. I am the void. Your flames will be extinguished, just like your hope."
Without warning, the Shadowmaster extended its hand, sending a torrent of shadow tendrils toward Saitama. The black tendrils moved like serpents, slithering through the air, aiming to ensnare him and snuff out his fire.

[New Skill Unlocked: Inferno Burst — Unleash an explosion of fire that incinerates everything within a 10-meter radius.]
---
Saitama smirked as the system message appeared before his eyes. "Not today."
With a roar, he activated **Inferno Burst**, his body erupting in a massive explosion of fire. The blast sent shockwaves through the reactor room, the walls trembling under the force of the explosion. The shadow tendrils were vaporized instantly, reduced to ash in the face of Saitama's blazing inferno.
The Shadowmaster recoiled, its form flickering as it struggled to maintain its shape. For the first time, Saitama saw a hint of fear in the creature's glowing eyes.
"You're not so invincible after all," Saitama taunted, stepping forward with molten flames rippling off his body.
The Shadowmaster snarled, its voice trembling with rage. "You dare challenge me?!"
It launched itself at Saitama, its form dissolving into a massive wave of darkness that surged across the room, engulfing everything in its path. The temperature plummeted, and the darkness threatened to choke the very air out of Saitama's lungs.
But Saitama wasn't backing down. The fusion with Magmate had turned him into something far beyond human—a being of pure fire and power.
"Magmate, let's show this thing who the real king of this ship is."
Magmate roared in agreement, and Saitama felt the creature's power surge within him. His body flared brighter, the molten glow intensifying until it became a blinding inferno.
Saitama raised his hand, channeling all of his energy into one single point. The heat around him skyrocketed, and the reactor room's metal walls began to warp and melt under the sheer intensity of it.
"Take this," he growled through gritted teeth, "and burn!"
With a final shout, he unleashed **Inferno Strike (Lv. 3)**, his most powerful attack yet. A colossal wave of fire erupted from his hand, crashing into the wave of shadows like a supernova. The two forces collided with a deafening explosion, and the entire ship shook from the impact.

[Warning: Structural damage to *The Argentum* detected.]
---
The system's warning blared in Saitama's mind, but he didn't care. This was the endgame.
The flames surged forward, devouring the Shadowmaster's darkness. The creature screamed, its form flickering and disintegrating under the relentless assault of fire.
"NOOOO!" the Shadowmaster shrieked as the flames consumed it, its voice filled with agony and rage. "You cannot defeat me! I am eternal! I am—"
But before it could finish, the flames overwhelmed it completely, reducing it to ash in a matter of seconds.
The darkness was gone. The reactor room was silent.
Saitama stood there, breathing heavily, his body still glowing with the remnants of the fusion. Magmate's presence was strong within him, but even that immense power couldn't mask the exhaustion that was beginning to take hold.
---
[Congratulations! The host has defeated the Shadowmaster.]
[Mission Complete: Reactor Room Secure.]
[New Skill Unlocked: Magmate Overdrive — Push the fusion beyond its limits, gaining temporary invincibility and overwhelming power. Warning: Excessive use may result in total system shutdown.]
---
Saitama grinned as the system messages flashed before him. He'd done it. He'd won. But there was no time to celebrate. The system's final warning rang out in his mind.
---
[Warning: *The Argentum* is sustaining critical damage. Reactor overload imminent. Evacuation is recommended.]
---
"Great," Saitama muttered, looking around at the reactor room's collapsing walls. The ship wasn't going to hold together for much longer.
"We need to move," he said aloud, more to himself than to anyone else. Magmate's low growl echoed in his mind, urging him forward.
Together, they dashed out of the reactor room, the floor beneath them cracking and crumbling as the ship's structure began to give way. Saitama could feel the intense heat of the reactor overload building behind him, but he didn't slow down.
---
As they reached the corridor leading to the escape pods, the system's final message appeared.
---
[New Mission: Escape *The Argentum* before the reactor explodes.]
---
Saitama glanced at the countdown timer ticking down in the corner of his vision. They had less than five minutes to escape.
He picked up the pace, the flames around him flaring as he pushed himself harder than ever before. The walls of the ship were melting, and the air was thick with smoke, but Saitama didn't falter.
"Come on, Magmate. Let's get out of here."
Magmate growled in agreement, its molten body flaring brighter as it pushed itself to the limit.
They reached the escape pods with seconds to spare. Saitama slammed his fist into the control panel, and the door hissed open. He leaped inside, and the pod launched into space just as *The Argentum* began to explode behind them.
---
Saitama watched through the viewport as the ship was engulfed in a massive explosion, the shockwave rippling through the void of space. He sighed in relief, his body finally relaxing as the pod drifted away from the wreckage.
---
[Mission Complete: Escape Successful.]
[New Skill Unlocked: Solar Nova — Harness the energy of a dying star to unleash a catastrophic explosion. Warning: This skill can only be used once.]
---
Saitama chuckled, shaking his head. "Solar Nova, huh? That's one hell of a skill."
Magmate's growl of approval echoed in his mind.
The battle was over, but Saitama knew this was just the beginning. He glanced at the stars outside the viewport, his mind already focused on what lay ahead.
