Strictly speaking, for the first native Transformer born on Earth, a being with such commemorative significance, Leon did not simply pick a random "lucky participant" from the streets of New York.
Instead, he located a Peterbilt classic American long-nose semi-truck parked in a warehouse belonging to Stark Industries, normally used for delivery logistics.
When the AllSpark's energy swept across it, the truck's body trembled slightly. Within moments, the transformation was complete.
Cold machinery had become a sentient mechanical lifeform—the first Transformer on Earth besides Arcee.
After awakening, the newborn Transformer instinctively attempted to shift into its humanoid form and kneel before Leon, its creator.
But an invisible force restrained its movements completely.
"Creator?"
The newly born consciousness sounded confused.
"Now isn't the time for you to reveal yourselves," Leon explained with a smile, placing a hand on the truck's hood.
"For now, hide within human society and coexist peacefully with humanity."
"Starting today, you will be the leader of all Transformers on Earth."
"Your name is—Optimus Prime."
"Thank you for the name bestowed by the great Creator. Optimus Prime will faithfully follow your command."
Optimus Prime's voice was deep and magnetic, like that of a calm and dignified gentleman.
But anyone who mistook that for weakness would be gravely mistaken.
Just as he had done with Megatron, Leon also produced large quantities of Adamantium mined by his Vibranium Miner system, forging for Optimus Prime an indestructible Adamantium body.
At the same time, he infused him with as much AllSpark energy as possible.
At present, very few superheroes on Earth could confront Optimus Prime head-on.
The sheer advantage of his size and tonnage alone was enough to overwhelm most enhanced individuals.
At minimum, someone like the future, more experienced Spider-Man might barely stand a chance—relying on agility, strength, and webbing tactics—and even then victory wouldn't be guaranteed.
"Do your job well. Stark Industries' covert security and delivery operations are now under your supervision."
"If you need guidance, consult Pepper Potts. Aside from me, she's your direct superior."
"And there's Tony—he comes as a bonus with the phone plan."
"Understood, Creator."
Optimus Prime's headlights flashed in acknowledgment. He had no objections to Leon's commands—after all, his very life had been granted by his creator.
Leon nodded.
With a brief teleportation, he disappeared from the garage.
Starting from Stark Tower, he began his grand act of creation.
In simple terms—
"Light up whatever isn't lit."
…
One Week Later
Leon had only managed to convert about half of the electronic devices within the United States.
Not because he was slow.
He simply wasn't in a hurry.
He traveled around with Arcee·A2, Bast, and 2B, turning the work into something closer to sightseeing while casually converting electronics into Transformers along the way.
At the same time, he had to avoid drawing too much attention.
After all, Leon intended his Transformer army to remain a hidden trump card.
Unlike Sakaar, which was mostly wasteland with electronic devices concentrated in the Grandmaster's cyber city, Earth's technological level might be lower—
but the density of electronic devices was far greater.
…
Queens, New York
Peter had just finished school.
Carrying his backpack, he walked home with Aunt May, who had just gotten off work.
At the entrance of their apartment building, they spotted an extremely eye-catching yellow convertible sports car.
The man in the driver's seat wore a baseball cap and sunglasses. He waved toward them.
"Hey~"
"Miss me?"
"Uncle Leon?!"
"Leon?!"
The aunt and nephew exclaimed at the same time before excitedly rushing toward him.
The car doors opened automatically.
Leon smiled, pulling them both into his arms—his left arm wrapping around May's slender waist, while his right hand lifted Peter easily.
"Muah!"
He gave Peter a quick peck on the cheek.
Then Leon met May's eyes—and immediately pulled her into a deep French kiss.
If Peter hadn't been right there, the two of them might have kept going endlessly.
"You actually found time to visit Peter and me?"
Feeling slightly breathless, May pulled away and leaned against Leon's chest as she asked.
"That's because today is your birthday."
"There's no way I'd forget."
Leon playfully squeezed her with Leon's Grip, then gave her lips another affectionate peck before turning her toward the car.
"Do you like it?"
"THAT'S SO COOL!"
Peter's eyes sparkled with excitement as he answered before May could.
He jumped out of Leon's arms and ran around the car, touching it here and there with fascination.
"Isn't it too expensive? And… it's so conspicuous…"
May felt a little embarrassed even imagining herself driving it.
"It's fine. It can change its appearance and color anytime you ask."
"Its artificial intelligence is excellent—you can basically treat it like a pet."
Peter lovingly stroked the car on one side.
Meanwhile, Leon was also quite fond of "handling" the curves of another "vehicle" beside him.
"Huh?"
"A pet?"
May felt slightly reassured, though the idea of treating a car like a pet still seemed strange.
Just then—
A youthful voice suddenly came from the vehicle.
"Aunt May, my name is Bumblebee. I'm happy to serve you and Peter."
"It talked?!" ×2
May covered her mouth in shock.
Peter's eyes lit up.
"Bumblebee! Can you transform like Arcee does?"
"Yes."
"Awesome! That's amazing! Transform for me!"
Peter climbed into the driver's seat, shaking the steering wheel excitedly.
Anyone who didn't know better might think the car had been gifted to him.
"According to the confidentiality agreement set by the Creator, I cannot transform in public."
On the car's display screen, a slightly chibi-style Bumblebee icon appeared, glancing sideways.
Right at that moment, an elderly neighbor was returning home and smiling politely at them.
"Okay…"
Peter pouted, clearly disappointed.
But the next moment, his expression brightened again.
Because Leon said—
"This time, it's allowed."
Beside Leon, Arcee·A2 appeared silently.
An optical camouflage field instantly spread outward.
Then—
under the increasingly astonished gazes of May and Peter—
Bumblebee transformed.
Panels shifted and folded.
Metal structures rotated and expanded.
Within seconds, the yellow sports car had transformed into a six-meter-tall Transformer warrior.
Carefully, Bumblebee caught Peter as he slipped from the driver's seat.
Then the massive Autobot knelt on one knee before Leon and May.
