I am Sam witwicky(SI)

The vast desert lay under a blanket of darkness, the silence shattered by Megatron's relentless pursuit. His massive form thundered forward, his red optics burning with malice. Sam's heart pounded as Bumblebee zigzagged wildly, evading blasts from Megatron's cannon that erupted around them in bursts of flame and debris. The explosive impact sent the convoy into chaos, forcing each SUV off-road and scattering them across the terrain near the Hoover Dam Lodge and Casino. As they neared the crumbling remains of the Hoover Dam Lodge and Casino, a final blast forced Bumblebee to swerve hard, flinging the rest of the convoy of SUVs off-road and scattering them into the rough terrain.

Bumblebee transformed in mid-motion, shifting from car to robot with precision. Sam and Mikaela hurtled through the air, Sam clutching the AllSpark tightly, as Bumblebee's metal arms snapped up, catching them before they hit the ground. Setting them down safely, Bumblebee immediately readied himself, his stance unyielding as he faced Megatron head-on.

"Take cover Sam!" Bumblebee said with a serious tone , but his resolve was clear.

Megatron scoffed, his towering form casting a dark shadow across Bumblebee. "Pitiful! Do you think you can stand against me alone, scout?" His metallic voice dripped with disdain. " A pitiful scout to dares to challenge me? haha I'll tear you limb from limb!"

Bumblebee ignored the taunt, his fists tightening as he charged forward, sending shockwaves through the ground with each step. Sam, pulling Mikaela into cover behind a jagged piece of rubble, couldn't tear his eyes from the battle unfolding in front of them.

Meanwhile, in the distance, Lennox, scrambling out of his SUV with his team, quickly found cover amidst the crumbling casino structure. He spotted the Decepticons approaching from the distance, a handful of dark forms moving with lethal precision. Epps guided Sam's parents, Sergeant Keller, Banachek, and Simmons into a sheltered nook, eyes wide as they witnessed the chaos around them.

"Lennox, we've got company !" Epps shouted, gesturing to the Decepticons advancing on their position.

"We will have to hold them off until the Autobots get here!" Lennox yelled back, already firing rounds at Megatron to draw his attention away from Bumblebee. His gaze swept over the destruction and locked onto Sam and Mikeala as they were in the proximity of Bumblee Bee and Megatrons clash and said "Sam!" Lennox shouted from his cover, his voice filled with both fear and awe. "Get out of there, kid!"

Megatron turned around and faced where the bullets were coming from and pointed his blaster cannon at lennox but just then Bumblebee took advantage of Megatron's momentary distraction, charging forward with a roar and blocking him from firing his cannon . He then tackled Megatron from the side, slamming him to the ground as sparks and metal flew. "You're fight is with me Megatron!" Bumblebee's voice was filled with determination as he wrestled with the Decepticon leader.

Mikaela, crouched beside Sam, grabbed his arm, her face pale with fear. "Sam, what are we going to do? We can't fight them!"

Sam was silent, his mind racing, clutching the AllSpark to his chest. It pulsed in his hands, its energy alive, resonating with him on a level he couldn't explain. As if answering his call, a faint buzz crackled in his ear.

"Master Sam," Alfred's voice came through the earpiece. "The suits are ready and in route to your location."

Sam's gaze sharpened, his heart steadied. He turned to Mikaela, giving her a reassuring look. "Trust me, Mikaela. Everything's going to be okay."

Before she could respond, he stepped back, lifting his arm out to the side. As if in answer, the first piece of his Iron Man suit shot through the air, glowing red under the dark sky as it clamped onto his arm. Piece by piece, the suit assembled around him with smooth, precise clicks, forming a powerful exoskeleton that felt both foreign and familiar. The gauntlets secured themselves over his hands, followed by the chest plate and leg armor that locked into place with a satisfying hiss. As the last piece of armor—the helmet—descended over his face, Sam felt the HUD light up, bathing his vision in a blue glow.

"Whoa!" Mikaela's eyes widened, watching in stunned disbelief as the Iron Man suit completed itself around Sam. "Sam, what… how…?"

Through the helmet, his voice sounded deeper, more mechanical. "I've been working on a few things." His gaze met hers, and he smiled under the mask. "so stay here i've got everything covered."

A mix of emotions crossed Mikaela's face—shock, awe, and a flicker of relief. Sam, holding the AllSpark tightly in his hand, turned toward Megatron, who had momentarily paused his assault on Bumblebee, his optics zeroing in on the unexpected arrival of Sams suit .

Just as he finished, red and silver streaks shot through the night, hovering briefly in the air before different metal suits descended over Sams allies.Everyone stared in shock as pieces of sleek, armored suits hovered around Lennox, Epps, Simmons, Banachek, and even Sam's parents, forming protective wall of suits . They exchanged wide-eyed glances, barely able to comprehend what was happening.

"Sam, what… what are is going on and what are these suits ?" Lennox managed, his tone laced with a mix of shock and awe.

Simmons, looking at the armored suits with disbelief, muttered, "How did a kid get his hands on this type of tech?"

Under his mask, Sam grinned as he responded through the speakers of his suits . "Just…abit of precaution . Now, stay low, and the suits will protect you."

As Sam finished, he clutched the AllSpark tightly, the light from the ancient relic casting an eerie glow on Megatron, who now paused mid-assault, his optics fixed on Sam's transformation and the armored suits around them .

Megatron's lips twisted into a sneer as he took in the sight of Sam, now suited up. "A human… in armor?" His voice dripped with disdain, but there was a glint of amusement in his optics. "Is this supposed to be your last stand, fleshling? Pathetic."

Sam clenched his fists, feeling the suit's power surge through him. He steadied himself, the thrusters in his boots humming as he activated them, lifting slightly off the ground. "You want the AllSpark, Megatron?" Sam's voice rang out, filled with a confidence that surprised even Bumble bee . "Come and get it."

Megatron laughed, a low, mocking sound. "I am going to enjoy destroying you ,human ." His cannon charged, dark energy crackling as he aimed directly at Sam.

"Sam!" Bumblee bee shouted , his voice filled with both fear and worry . "Get out of here !"

But Sam stood his ground, raising his arm. The repulsor beams glowed, mirroring the light of the AllSpark in his hand. Glancing back at Mikaela, he nodded, offering a comforting smile beneath the mask as a suit of armour flew next to Mikeala he said . "I've got this. This suit of armour will keep you safe ." Mikaela, who stared at him with wide eyes, her voice barely a whisper. "Sam… be careful."

Without a second thought, he activated the repulsors, he launched himself into the air, dodging to avoid Megatron's blast, which shot past him, erupting in an explosion of sand and debris. Sam retaliated, aiming his repulsor beams at Megatron's shoulder joint, the powerful energy strikes landing with precision, forcing the towering Decepticon to stagger back. The wind roared around him as he flew, the stars above blurring into streaks of light. 

Meanwhile, Bumblebee, spurred by Sam's bravery, launched himself at Megatron's legs, aiming a powerful kick that caused Megatron to stumble.

"Foolish human !" Megatron spat, shoving Bumblebee back with a swipe of his arm.

Down below, Lennox and the others watched in a stunned silence. Banachek, unable to look away, muttered in awe, "Did… did anyone else know he had this up his sleeve?"

Simmons, equally stunned, could only shake his head. "No one told me I'd be in the middle of a battle with alien robots, let alone with a teenager wearing a suit of advanced armor leading the charge and protecting us ."

Even Sam's parents, though protected by the suits of armor, stared with wide eyes, their shock mixed with an unmistakable glimmer of pride and worry.

Sergeant Keller, who had ducked back to safety with Epps, shouted above the din of the battle, "If we live through this, I want answers because someone's going to have to tell me how a teenager got such a sophisticated piece of armor!"

Epps, helping Sam's parents find cover, turned to Banachek and Simmons. "Never thought I'd be part of a battle like this. This is some serious alien invasion level stuff."

Back in the fray, Sam dodged a swipe from Megatron, rolling mid-air before firing his repulsor beams at the Decepticon's face. The energy beams hit Megatron's armor, staggering him momentarily. Sam steadied himself, gripping the AllSpark as he hovered in place, feeling the excitement bubbling in him due to fighting someone like Megatron .

"Megatron!" Sam shouted, his voice carrying over the battlefield. "You're not taking this from me !"

Megatron glared at Sam, his optics narrowing. "I will rip that piece of armor from your body as i tear the allspark away from you myself, fleshling," he growled.

In response, Sam face became serious under his mask as boosted forward, and said "i would like to see you try!" ready to face Megatron head-on.
