X-GENE OMNITRIX-Chapter 43: XGO - 40

The sanctuary burned.

Alex, still wielding the power of Susanoo, stood in the devastation as Sam—possessed by Mephisto's essence—circled overhead. The World Tree Avatar wrestled with the corrupted T-Rex while defenders scrambled to evacuate the children. All seemed lost as the rift to Hell widened above them.

But something was wrong.

Or rather, something was exactly as planned.

Amid the chaos, a figure stepped through a shimmering doorway that hadn't been there a moment before. Dressed in flowing emerald robes with ancient runic symbols glowing along the edges, the Ancient One's appearance commanded immediate attention. Her eyes, filled with cosmic awareness, took in the battlefield with calculating precision.

"It seems your gambit has reached its breaking point, Alexander," she said, her voice somehow carrying over the din of battle.

Sam paused mid-flight, his corrupted form momentarily confused by the new arrival. The hellfire wings faltered for just a heartbeat.

Alex's Susanoo form dissolved in a flash of light, returning him to human form. But instead of panic, his expression showed something else entirely.

Satisfaction.

"Right on schedule," he said, checking the Omnitrix on his wrist. The device, normally glowing green when ready for transformation, had been pulsing between red and blue for days—ever since Sam's rescue.

The Ancient One moved her hands in a complex pattern, and the air around them shimmered. The battlefield, the burning sanctuary, even the rift to Hell—all froze in place like a paused video.

"You've been busy," she remarked, walking casually through the frozen chaos. "Creating all this couldn't have been easy, even with the tools at your disposal."

Alex smiled grimly. "Sometimes the only way to catch a demon is to let it think it's winning."

With a practiced motion, he twisted the dial on the Omnitrix, bypassing his usual battle forms. The device flashed, and in place of Alex stood a small, blue robotic cat with a white stomach and a dimensional pocket on its front.

Doraemon.

"I suspected something was wrong the moment we rescued Sam," Alex explained in Doraemon's higher-pitched voice. "The Omnitrix went into defense mode immediately."

He reached into his dimensional pocket and pulled out a small, ornate device that resembled a handheld mirror with strange circuitry around its edges.

"Mirror World Creator," he announced, holding it up. "Everything Mephisto thinks he's been seeing and influencing has been a dimensional duplicate."

The Ancient One nodded appreciatively. "The Mirror World technique. Risky, but effective. When did you implement it?"

Alex gestured toward the frozen lake at the edge of the sanctuary.

"After we brought Sam back. The Omnitrix detected Mephisto's energy trying to breach its defenses. It wasn't just scanning Sam—it was warning me. When Sam went for a swim in the lake that first day, I added the Mirror Liquid to the water."

A flashback showed Alex as Doraemon, secretly dropping a luminescent blue liquid into the lake just before Sam dove in. When Sam emerged from the water, he passed through an invisible barrier—one he never noticed. The real Sam had been quietly moved to safety, while a perfect duplicate, created from a single strand of his hair, continued in the mirror world.

"And the Omnitrix's color changes?"

"Red when detecting Mephisto's breach attempts," Alex explained, "blue when confirming the mirror world's integrity. It's been monitoring the barrier between realities, making sure Mephisto couldn't detect the deception."

The Ancient One waved her hand, and the frozen scene shifted. They now stood in what appeared to be an observatory above the mirror world—a hidden command center where the real Alex had been monitoring everything.

Screens displayed multiple angles of the sanctuary battle. On a central table, a three-dimensional model of the World Tree glowed, showing power flows and barrier integrity. Several of Alex's allies—the real Elara among them—worked at various stations, monitoring the elaborate illusion they had created.

"The mirror world reflects and amplifies," Alex continued. "Everything Mephisto thought he was experiencing was carefully designed to make him believe his possession of Sam was succeeding. Every crack in our defenses, every breach in the sanctuary—all calculated to draw him further in."

"And the real Sam?" the Ancient One asked.

Alex pointed to a chamber below, where the actual Sam rested in a protective healing pod, observed by medical staff. "Safe. Protected. And most importantly, clean of Mephisto's influence. We extracted the demonic energy the moment we detected it."

The Ancient One studied the simulation of the rift to Hell displayed on the main screen. "And now Mephisto thinks he's about to claim victory."

"Exactly." Alex's Doraemon form reached into his pocket again, withdrawing another device—this one resembling an ornate compass with crystal components. "The Mirror Trap. When Mephisto fully manifests through what he believes is a rift to our world..."

"He'll actually be entering a sealed dimensional pocket," the Ancient One finished. "Clever. The demon lord has been so focused on breaking through what he perceives as reality, he hasn't noticed he's been following a script."

Alex nodded, returning to his human form with a flash of light. "The World Tree Avatar, the corrupted dinosaurs, even my Susanoo form—all parts of the illusion designed to provoke exactly the response we wanted." He gestured to the screens. "Look."

In the mirror world, Mephisto's essence was now pouring through the rift much faster, believing the sanctuary's defenses were crumbling. The demon lord's actual throne was becoming visible, his true form beginning to manifest as he prepared to claim his victory.

"It's time," Alex said, picking up what looked like a modified version of the Omnitrix—this one designed to interface with the mirror world. "We've drawn him out.

In the mirror world, Mephisto's essence was now pouring through the rift much faster, believing the sanctuary's defenses were crumbling. The demon lord's actual throne was becoming visible, his true form beginning to manifest as he prepared to claim his victory.

"We need to enter the mirror world now," Alex said firmly. "It's time to face him directly."

The Ancient One nodded gravely. "Remember, once we're inside, we'll be subject to the same rules as everything else in that dimension."

"I understand the risks," Alex replied, activating a portal function on the device. A shimmering doorway appeared before them, showing the chaotic battle occurring in the mirror world.

Without hesitation, Alex and the Ancient One stepped through into the raging conflict. The heat of hellfire immediately washed over them as they materialized amid the burning sanctuary. Above them, Mephisto continued emerging through the massive rift, his throne of tortured souls descending into what he believed was the real world.

The demon lord's eyes widened in surprise at their sudden appearance. "The sorcerer supreme?" Mephisto growled, his attention momentarily diverted from completing his manifestation. "This sanctuary holds more secrets than I anticipated."

As Mephisto's consciousness fully engaged with the mirror world, something unexpected happened. His vast awareness, no longer focused solely on the sanctuary, began to expand outward across the fabricated Earth. The demon lord's expression shifted from triumph to confusion, then to rage.

"What is this?" Mephisto roared, his partially manifested form flaring with intensified hellfire. "Where are the billions of souls? WHERE IS EVERYONE?"

Around Alex and the Ancient One, the mirror world beings—the duplicates of the sanctuary defenders—began to destabilize. Their forms flickered, then crumbled into dirt that fell away in clumps. The possessed Sam duplicate, the World Tree Avatar, even the hellbeasts—all turning to soil and dust before their eyes.

"There is no one else," Alex called up to the enormous demon lord. "This entire world is empty. Always has been."

Mephisto's fury erupted in waves of infernal energy that scorched the already burning landscape. "IMPOSSIBLE! I WOULD HAVE SENSED A FALSE DIMENSION!"

"Not this one," Alex replied calmly as more of the world crumbled around them. "The Mirror World isn't magical in nature—it's technological. There's no mystical signature for you to detect."

Mephisto extended massive claws toward them, his throne now fully emerged through the rift. "HOW DARE YOU DECEIVE THE LORD OF HELL!"

The Ancient One stepped forward, hands raised in complex defensive patterns. "It was necessary to draw you out, Mephisto. To make you reveal yourself."

"The real Sam is safe," Alex added. "The real sanctuary untouched. You've spent your energy conquering an empty stage."

As more of the mirror world dissolved into dirt, Mephisto unleashed his full rage. The demon lord abandoned all pretense of using vessels or proxies, his true form now fully materializing—a towering entity of ancient malevolence with eyes of liquid hellfire and a crown of twisted horns that seemed to pierce reality itself.

"I WILL DESTROY YOU BOTH!" Mephisto bellowed, sending chains of burning brimstone whipping toward them. "THEN I WILL FIND YOUR REAL WORLD AND BURN IT TO ASH!"

The Ancient One deflected the chains with shields of golden energy while Alex reached for the Omnitrix.

"You won't find anything," Alex said, activating the device. "Because we're taking you down right here."
