MHA: Mewtwo

The U.A. students were gearing up for their internships. Following recent events, everyone had been training with unmatched determination, pushing their limits to prepare for the challenges ahead. During the final week, no one wasted a second on anything unrelated to their goal.

Classes shifted to focus entirely on practical exercises, supported by the addition of two extra teachers. One remained in the control room, monitoring the students' progress, while the other worked directly with each group during their hands-on training. Throughout the week, students put their theoretical knowledge into practice, tackling increasingly complex scenarios.

The training covered a wide range of situations: preventing kidnappings, managing natural disasters, responding to traffic accidents, thwarting robberies, and neutralizing villain attacks. The teachers meticulously corrected mistakes, offering guidance and encouragement. The hardest skill to master was controlling damage—resolving conflicts and engaging in combat without causing harm to private or public property.

When the intense ten-day training period concluded, each student was assigned to a hero agency for their internship, ready to step into the real world of heroism.

Raiden stood before a traditional Japanese building, the headquarters of Musashi, Japan's eighth-ranked hero. The structure, with its weathered wooden beams and gracefully sloping roof, radiated an air of timeless authority.

As he stepped inside, the atmosphere was no less impressive. The interior was a tribute to classical Japanese aesthetics, with polished wood floors, sliding paper doors, and a faint scent of incense lingering in the air. Carrying a backpack, a duffel bag, and a suitcase containing his hero armor, Raiden advanced cautiously, taking in his surroundings. This was where he would live and train for the next week—a chance to prove himself under the guidance of a true legend.

Just as he approached the receptionist's desk, a door slid open with dramatic force. Raiden turned to see a figure stepping out—a man clad in full samurai armor, his presence commanding respect. It was Yoroi Musha himself.

"Good, you're here," Yoroi Musha said, his voice firm yet measured. "You already know who I am, and I know who you are, so we'll skip the introductions. You can call me Sir Yoroi. Now, we don't have time to waste—villains don't wait. Your assessment begins immediately."

With a sharp gesture, he signaled to a staff member nearby. "Miss Asuri, take the young man's belongings to his room."

He turned back to Raiden, his piercing gaze locking onto the young hero. "Also, boy, bring your hero suit."

Without hesitation, Raiden nodded and followed the seasoned hero through a corridor that led to a waiting room. Yoroi pointed toward a nearby locker room. "Change quickly," he instructed.

Raiden wasted no time. Minutes later, he emerged fully dressed in his hero armor. The suit, recently repaired after a prior training mishap, gleamed as if brand new. Its sleek design gave him an air of readiness that matched his determined expression.

Yoroi Musha appraised him with a nod of approval. "Good. Now, let's see if you're as ready as your suit makes you look."

When Raiden was ready, he stepped into the grand hall. The room was adorned with exquisite Japanese paintings depicting landscapes and warriors, their brushstrokes delicate, and expensive thought Raiden. In the center stood a bonsai tree, its branches carefully sculpted to perfection, radiating an air of tranquility. Raiden paused, captivated by the elegance of the space.

Before he could fully appreciate everything, Yoroi Musha's voice broke through his thoughts. "Young Raiden," the pro hero began, his tone firm but not unkind, "now that we are both properly dressed, we can officially begin your internship. Here, you will accompany me and learn everything you can. If you have questions, ask. My duty is to guide you."

Raiden hesitated for a moment, surprised. From what he had seen in interviews, Yoroi Musha was rumored to be impatient, even arrogant. Yet in person, the man carried himself like a wise old man rather than a ball of ego.

"Thank you, sir. I'll be in your care," Raiden replied earnestly, bowing his head slightly.

Yoroi Musha gave a curt nod, his eyes sharp with determination. "Good. Now, let's go. Even on your first day, there's no time to waste. We'll start patrolling this side of the city. Listen carefully, kid. I'm aware of your Quirk, and under my authority, you now have permission to use it—but only for movement, flight, and self-defense. You are not to engage in battle on your own initiative unless I explicitly order it. Is that clear?"

"Yes, sir," Raiden answered immediately, his voice steady. He knew top heroes had the authority to grant students limited use of their Quirks, but he hadn't expected such trust right away.

With that, the two stepped out into the bustling city streets. Raiden's heart raced with anticipation as his internship officially began, a whirlwind of responsibility and opportunity waiting just ahead.

Elsewhere, in a sterile, dimly lit laboratory, a man in a white coat stood before two fascinating specimens. One was a massive tentacle suspended in a cylindrical glass tube, its surface shimmering faintly under the fluorescent lights. The other was a small vial of crimson blood. On a nearby desk sat a red envelope containing a letter and two folders.

The man opened the envelope, revealing a sleek black sheet of paper with crisp white text:

Esteemed Evolver,

As a gesture of goodwill, I am sending you two samples belonging to two promising young boys. Each possesses a transformation-type Quirk of extraordinary potential.

The first sample, a vial of blood, is from a psychic-type user who has demonstrated incredible abilities, ranging from telekinesis to healing.

The second, a giant tentacle, belongs to a user whose body exhibits the capacity to transform into multiple life forms. I trust these will aid in your research.

However, I must warn you: these samples are from students at U.A. High. Acquiring more will be difficult for now. Along with this letter, I have included detailed folders on both individuals.

The man's eyes glowed an intense, electric blue as he read the documents, intricate circuit-like patterns forming around his temples. "Interesting," he murmured, his voice low and melodious, with the calm authority of a seasoned radio announcer.

He approached the glass tube containing the tentacle. Mechanical arms extended from within the cylinder, cutting a small section of the specimen. The severed piece was carefully placed between two microscope slides, and the man moved swiftly to examine it.

"Edward, You dam brute, your instincts and luck never cease to amaze me" the man mused, his lips curling into a faint smile. "This… this will be invaluable for the evolution Quirk process, finally a hope to fight him."

Under the microscope, the sample revealed its secrets. The cells pulsed with a strange vitality, vibrating and altering their structure. Some resembled octopus cells, but they were connected by an intricate neural-like network, constantly exchanging information. The possibilities of this were staggering.

"It's been a long time since I've seen something with this level of potential," he muttered, his excitement barely contained. This discovery was a breakthrough for him, one that could redefine his research. Setting the slides aside with care, he turned his attention to the vial of blood.

"Now, let's see what this psychic can offer," he said, a note of anticipation in his voice as he prepared to examine the second sample.

He carefully drew a drop of blood from the vial, mindful of the limited quantity. This sample was far smaller than the others and required extra caution.

Placing the sample under the microscope, he began his analysis. At first glance, the cells seemed unremarkable. They reacted to electrical stimuli, shifting between two stable forms—one resembling human cells, the other distinctly different. Unlike Tamaki's sample, these cells lacked the dynamic, interconnected structure that had fascinated him earlier. On the surface, nothing appeared out of the ordinary for a transformation-type Quirk.

Still, he wasn't convinced. Edward never sent anything trivial. If the file's notes were accurate, this boy's abilities were exceptional. There had to be more to uncover.

He carefully transferred a portion of the blood sample into a vial, adding a reactive compound. With steady hands, he loaded the vial into a centrifuge and set the machine spinning. The hum of the centrifuge filled the room as he stepped away, allowing the process to unfold.

While he waited, the man left the lab and prepared a pot of coffee. He took his time, sipping from a steaming cup and nibbling on a handful of cookies. Patience had always been his virtue. An hour later, he returned to the lab, where the centrifuge had finished its work.

Eagerly, he removed the vial and placed its contents under the microscope. What he saw made his breath catch.

"What the...?" he muttered, leaning closer to the lens.

The sample was unlike anything he had encountered. Raiden's DNA was present, as expected, coding for his form and abilities in the usual manner of Quirk-bearing individuals. At first glance, one might assume this could make Quirk replication theoretically possible. After all, if Quirk-related information was encoded in DNA, isolating and replicating it should be feasible.

But it wasn't that simple.

To replicate a Quirk, one would need to decode the entire sequence—an impossible task given the complexity. A Quirk-related sequence wasn't static; it was interwoven with sequences responsible for stabilizing the Quirk, sequences stabilizing the body, and countless others whose purposes remained a mystery. The human DNA changed incredibly since the emergence of Quirks, human DNA has become infinitely more intricate, branching into a web of near-infinite variables, making each individual almost a creature from a different species, but somehow, compatible between them.

But every DNA code shared one common trait, the dual sequence, and Raiden DNA was just like that, almost.

On one level, it appeared ordinary—Raiden's core genetic sequence coding for his human form and Quirk, just as expected. But surrounding the primary sequence were fragments of foreign DNA, floating freely and disconnected from the main structure.

This anomaly was baffling. If these sequences were disconnected, why were they present at all? What purpose could they serve?

Intrigued, he devoted himself to further testing. He separated mini-samples and exposed them to various reagents, trying to provoke a reaction or uncover some hidden characteristic. Each trial ended the same way—the sample destabilized under excessive stimulation, breaking down before offering any clear answers.

Finally, he leaned back in his chair, staring at the ceiling. His fingers tapped rhythmically on the desk as his thoughts churned. The additional DNA sequences didn't align with anything he understood. They were like vestigial remnants, seemingly without function—a genetic riddle.

"Am I looking at this the wrong way?" he murmured aloud, the question hanging in the air.

He muttered a quiet, "Maybe," and stood, his gaze settling on a nearby container holding Tamaki's tentacle sample. With careful precision, he extracted another small piece of flesh.

The next step was to isolate and purify both samples. From Tamaki's cells, he sought to strip away the octopus transformation, leaving only a raw cell with pure adaptive potential. From Raiden's blood, he worked to isolate and digitize the floating DNA fragments, converting their sequences into a readable format.

Hours passed as the man worked tirelessly, his machines humming around him. Test after test yielded no breakthrough until, after twelve grueling hours, the screen of his primary computer lit up.

[Isolation Successful]

He exhaled sharply, relief and excitement flooding his chest. With Tamaki's adaptive cells isolated, the real experiment could begin. He took a sample of Raiden's DNA fragments and prepared to fuse them with Tamaki's purified cells.

This wasn't about replacing Tamaki's adaptive factor—that would be counterproductive. Instead, he aimed to integrate Raiden's unused DNA chains into Tamaki's cells, testing how the fragments might influence their behavior.

The result left him stunned.

The previously unstable fragments from Raiden's DNA seamlessly stabilized Tamaki's cells. The fusion was smooth, almost perfect, and the cells reacted in a way he hadn't anticipated. His hands trembled as he stepped back, staring at the glowing display on the microscope.

His eyes widened, and a grin slowly spread across his face. Grabbing the lab's intercom, he pressed a button and spoke into it with unrestrained excitement.

"Send in a test subject. I have something to test, Also contact Edward, I will need more samples and test subjects."

The man in the white coat turned back to the lab table, his heart pounding with anticipation.
