Hulk

Charlie expected the defenses inside the alien cylinder to grow stronger as Batman advanced. Yet, after breaking through the first line of elite soldiers, there were no more significant obstacles. The interior was filled mostly with technicians and operators managing the fortress's systems. The absence of combatants made the rest of the mission much easier.

Switching Batman out of the Justice League Destroyer armor and into his standard stealth suit, Charlie continued the operation. Batman quickly incapacitated the non-combatants, taking control of the cylinder's systems. With the shields disabled, the massive structure lost its primary defense, becoming vulnerable to Earth's military firepower. Within moments, intercontinental missiles struck the cylinder, reducing it to rubble in a fiery explosion.

Realizing the pattern, Charlie divided the remaining objectives between Batman and The Flash. Batman, relying on stealth and precision, infiltrated and dismantled the defenses of the remaining cylinders. Meanwhile, The Flash, with his unmatched speed, destroyed fortifications before the enemy could even react. Together, they dismantled the network of terraforming devices scattered across the planet.

The alien automated turrets, while powerful, were ineffective. Batman's stealth systems rendered him invisible to sensors, while The Flash's speed rendered targeting systems useless. The stationed soldiers, though skilled, were no match for the combined ingenuity and power of Earth's defenders. In under thirty minutes, nearly all the alien cylinders were destroyed, leaving only two operational.

By this point, the enemy's terraforming plan had already failed. The system required all cylinders to function in unison. With the network broken, the remaining devices posed only minor threats, capable of causing localized weather anomalies but nothing close to planetary transformation.

As Batman prepared to teleport to the next site, Charlie began scanning for the enemy's mothership, knowing it had to be nearby. Such an extensive operation required a central command, and the Avengers stood ready to strike as soon as the coordinates were located. Before the final two cylinders could be dismantled, the aliens made their next move.

A blazing object streaked across the sky, leaving a fiery trail as it entered Earth's atmosphere. At first, it appeared to be another terraforming device—a massive, angular structure descending rapidly. But when it struck the ground, it began to change.

The object unfolded, expanding rapidly as metal appendages extended and anchored into the earth. Rails stretched outward, forming a massive, skeletal frame. Its body grew larger and larger, defying logic as it doubled, tripled, and continued to expand. By the time it stopped growing, the machine stood over 700 meters long, resembling a massive steel reptile with countless legs digging into the earth. Its back, armored with overlapping plates, loomed like an impenetrable wall.

Around the world, people stared in disbelief as the monstrous machine dominated the horizon. Its sheer size and ominous presence filled onlookers with dread.

In a distant medical bay, Jaeger—a wounded expert in alien technology—struggled to sit up, his eyes fixed on the live broadcast. "It's here... the Resetter," he muttered, his voice weak but urgent.

The medical staff rushed to his side, trying to keep him calm, but he continued, pointing at the machine on the screen. "That's their ultimate weapon. It's designed to wipe out everything on a planet's surface—ecosystems, life forms, structures. It transforms everything to suit their needs."

Meanwhile, Charlie received a report from Friday. "Its energy readings are spiking, sir. It's building power for something significant."

"Get the team ready," Charlie said. 

A teleportation array activated near the Resetter, releasing a bright light as the Avengers emerged, ready for battle. Thor charged forward, his hammer crackling with lightning. 

"Finally! A worthy opponent!" Thor roared. He leapt toward the Resetter, summoning a massive storm. Tornadoes swirled, and lightning bolts rained down, striking the machine's reinforced armor. Despite the barrage, the Resetter's plating absorbed the attacks, holding firm.

Iron Man flew in next, circling the massive machine while firing precision blasts. His attacks didn't aim to destroy but to gather data on the Resetter's defenses. His onboard systems quickly analyzed the results.

"The armor's layered with a reactive force field," Tony reported. "It responds to impacts, redirecting the energy back. The stronger the hit, the stronger the rebound."

Thor grinned. "Then let's test its limits!"

Tony smirked. "Hulk, Thor thinks he can crack it first. You gonna let him have that win?"

A massive green blur shot forward as Hulk leapt into action, roaring as he raised his fist and brought it down on the Resetter with all his might. The impact echoed like a thunderclap as the battle against the ultimate weapon truly began.
