One Piece: Trainers on the Straw Hat Pirates

When he reappeared, he was already inside a damp, dark cave.

This is the larval breeding base that Usopp created specifically for cultivating special insects.

In order to create a variety of different breeding environments, he even specially built several energy devices with Franky that could release energy such as fire, ice, lightning and life force using evolution stones.

At this moment, Usopp stood outside a huge metal door, looking excitedly at the situation on the other side of the door through a round, specially made glass.

"Was the experiment a success, Usopp?"

Seeing that Usopp hadn't noticed his presence, Scarlet stepped forward and asked him.

Overjoyed, Usopp seemed to have anticipated Red's appearance; without even turning his head, he waved and shouted:

"That's right! Come here quickly, Crimson!!!"

"Look..."

"This is the miracle of life I created!!!"

"Oh?"

With a curious look on his face, Scarlet walked over to Usopp's side and looked with him into the laboratory behind the metal door.

What came into view was a blazing fire!

Flames roared and spewed from every corner of the laboratory, as if trying to burn everything to ashes.

On the table in the center of the laboratory, there was a large patch of charcoal-like residue and a pile of large, burning, and writhing pupae.

These pupae have rings of flame-like patterns on their bodies, and each one is over a meter long.

Even a casual glance reveals thousands of them.

"These are the pupae of the Flame Butterfly!"

Just then, Usopp took the initiative to introduce himself to Red.

Although most of these bugs had passed through Crimson's hands, he had given them Pokémon status so many that he couldn't possibly remember the name and characteristics of every single one.

Usopp continued, "The Flame Butterfly is a special insect that I discovered at the Black Lion Alliance base."

"The surface of this insect's body has a thermal conductivity comparable to that of metal, and inside its body, there is a special organ that can store heat energy."

"When it encounters an enemy, it releases heat from its body surface to inflict damage on the enemy."

"After a series of iterative hybridizations and energy transfers, I have successfully developed a batch of larger Flame Butterflies that can store more heat energy!"

"After being induced to grow, the Flame Butterfly is now able to successfully release the insect powder and heat energy inside its body at the same time, creating outward flames to fight."

"After being granted the identity of a Pokémon, their average individual strength is comparable to that of pirates with bounties of several million Berries!"

"These pupae in the lab today are individuals I selected from countless larvae, those with immense potential!"

"Just before they were about to emerge from their cocoons, I put them all into my body's storage space and created an environment that reduced cellular activity."

"Everything is for this final experiment!!!"

Usopp said with a proud look on his face.

The achievement of creating a powerful insect species in just over a month is truly something to be proud of.

Even though Usopp mobilized a large amount of medicine and various evolution stones from Red in order to complete the experiment.

but……

"So... what are you doing right now!?"

Looking at the pupae that were gradually losing their vitality under the scorching flames and eventually turning into black charcoal residue, Chi Hong asked curiously.

Usopp, however, just grinned, completely bewildered.

"My original plan was to continue optimizing this population by constantly increasing the temperature of the flames, and to cultivate a more powerful Zerg."

"But just now, I suddenly realized that I don't seem to need to wait any longer!"

Usopp's eyes flashed, and he pointed a finger at the glass.

Chi Hong followed the direction of his finger and looked into the laboratory. Only then did she discover that among a group of pupae, there was a unique individual!

Compared to other flame butterfly pupae that wriggle in the flames to survive, the flame patterns on this pupa are darker in color, appearing even more intensely red than the surrounding flames.

The key is……

The pupa did not move at all; instead, it remained quietly there, its body rising and falling as if breathing.

With his extraordinary mental power, Crimson instantly "saw" a larva inside the pupa whose body was constantly growing and undergoing metamorphosis.

The terrifying heat surged in from outside the pupa, pouring into the larva's body. Instead of causing it burning or pain, the larva was quickly absorbed and transformed into special energy to fuel its growth.

Evolving in flames!!!

Upon seeing this scene, a thought flashed through Crimson's mind.

In fact, the special flame butterfly pupa was undergoing just such a process at that moment!

From larva to pupa, and from pupa to butterfly, isn't this the evolution that exists in nature?

"Is this... a genetic mutation!?"

Crimson immediately became interested in the unique Flame Butterfly pupa.

He suddenly reached out and summoned a dimensional portal, then said to Usopp:

"That's about enough... Let's move the rest of the pupae out."

"With proper nurturing, it will become another powerful Zerg army!"

"Then……"

A glint flashed in his crimson eyes.

"Let me personally confront this mutated fire butterfly!"

……

……

Half an hour later...

boom!!!

With a loud explosion, a massive shockwave swept through the entire flame laboratory.

The next moment, a butterfly with wings over a meter long suddenly flew out from the swirling flames, and from its center, another blazing halo of flames erupted.

The two enormous wings were a fiery red, as if painted by flames, and along their edges were golden ripples like the blazing sun.

Its body was entirely charred black, perhaps from being burned by the flames for too long, which damaged its surface.

"They're finally out!?"

"They're even genetically modified Zerg with their own fire vortexes!?"

Meanwhile, in the same laboratory, a red flamingo with outstretched wings, after seeing the fire butterfly successfully emerge from its cocoon, transformed back into human form and landed back on the ground.

After his test, this mutated pupa was indeed extraordinary!

Although it is unknown what level of high temperature it can withstand, under the flames released by Crimson that could easily burn an ordinary naval vice admiral, it not only showed no signs of injury, but also grew rapidly, accelerating the process of emerging from its cocoon!

"Squeak..."

The newly evolved mutated fire butterfly was suddenly stunned upon seeing the crimson human figure.

It had originally planned to properly thank the big bird after it emerged from its cocoon.

How could the bird have disappeared in the blink of an eye?!

Although it has successfully mutated, it is clear that an insect is still an insect, and its intelligence and knowledge are still at a low level in the biological world.

Just as the Flame Butterfly was puzzled, Usopp, seeing the mutated Flame Butterfly emerge from its cocoon, hurriedly went into the laboratory.

As he released the Bug-type energy that Flamebeet was familiar with, Flamebeet, who was originally searching for Moltres, instantly forgot everything and pounced on Usopp.

It attracted the pure nutrients that allowed it to grow quickly, while also becoming affectionate with Usopp.

Don't be fooled by Usopp's ruthlessness towards insects; he casually uses tens of thousands of insect lives for experiments.

But that's the racial structure of the Zerg.

In the Zerg race, everything the Zerg King does is absolutely correct.

Even if they wanted to kill them and use their bodies as nourishment, the swarm of insects would have no choice but to obey.

After a long period of communication and commands from Usopp, the Flame Butterfly finally acknowledged Crimson's identity as a "Zerg Trainer" and regarded him as a member of its own kind with a special status.

And so, Moltres naturally became a Pokémon and was taken into the Pokémon world by Red for a simple test.

You won't know until you test it...

The results of the Flame Butterfly test surprised even Crimson.

Initially, the Flame Butterfly's attribute panel looked like this:

Pokémon: Firebee

[Level: 12]

[Gender: Concave]

【Personality: Impatient (+Speed ​​-Defense)】

[Attributes: Insect, Fire]

[Ability: Flame Body (Pokémon with this ability unleash varying degrees of flames to deal additional damage to enemies during close combat, depending on their strength. Additionally, Pokémon with this ability can emit special energy from their bodies, promoting reproduction and the growth of offspring.)]

[Skills: Spark, Flame Vortex]

Experience points: 0/375

Total Attributes: 233

Level 12, with 233 attribute points, and also comes with two inherited skills.

Although it's not exactly a newborn, the fact that it has such high attribute stats at this level is enough to prove that Flame Butterfly's basic attribute talent ranks in the upper-middle range even within the Straw Hat Pirates.

After being leveled up by Crimson for a short period of time, the Flame Butterfly grew to level 20, and its attributes reached an astonishing 367!

Of course, what's amazing isn't the total attribute value of 367.
