Energy Explained: Directions of Evolution

Energy Explained:

The creatures in the world of One Piece were dozens or even hundreds of times larger than creatures on Earth. I decided this was because they possessed an additional kind of energy that Earth's creatures lacked: Evolution Energy.

Some powerful people in the world of One Piece had physical abilities and strength dozens or even hundreds of times greater than those of humans on Earth, yet their size had not changed much—except for Giants. So I decided they possessed another kind of energy that Earthlings lacked: Reinforcement Energy.

However, some creatures were not especially large but were incredibly strong, such as Kung Fu Dugongs, Fighting Fish, and the apes on the island where Hawkeye lived. Therefore, they possessed Reinforcement Energy.

Then there were people whose size far surpassed that of Earthlings, such as Giants. Therefore, they possessed Evolution Energy along with a certain amount of Reinforcement Energy.

The effects of energy:

Evolution Energy: It enabled growth and evolution, allowing one to surpass the limits of one's size.

Only after the protagonist consumed it could he extract biological traits from it and grow certain organs. This depended on his size—the larger the protagonist became, the more energy he needed to grow a particular organ.

Evolution Energy prioritized growth, then evolution. To grow a specific body part, he needed a creature with powerful Evolution Energy that possessed that body part.

Reinforcement Energy: It strengthened the body. After consuming it, one's physical strength increased.

The amount of Reinforcement Energy differed according to the power contained within the body and the body's durability. It was not limited to humans; special creatures had it as well.

So here is a classification:

Humans, excluding Giants: Reinforcement Energy.

Giant creatures: Evolution Energy.

Special creatures: Reinforcement Energy.

Giants: Large amounts of Evolution Energy and an indeterminate amount of Reinforcement Energy.

Fish-Men: Ordinary Fish-Men possessed large amounts of Reinforcement Energy and small amounts of Evolution Energy.

Giant Fish-Men: Large amounts of Evolution Energy and large amounts of Reinforcement Energy.

Many readers raised questions, so I'll answer them.

Question: Could eating people make him grow arms and legs?

Answer: Ordinary people could not break through the limits of their size and had no Evolution Energy.

Question: Why didn't the protagonist evolve shrimp claws after eating shrimp at the beginning?

Answer: Those shrimp were ordinary sea shrimp, only ten to thirty centimeters long. They existed on Earth as well, so they had not surpassed the limits of their size and did not possess Evolution Energy.

Question: If he ate a Giant, could he grow arms and legs?

Answer:

In principle, yes. But their most significant traits were other parts: the spine, warm-blooded live birth, and lungs.

However, a thirty-meter Giant weighed around two hundred tons. For the protagonist to eat one, he would need to weigh at least ten thousand tons. (His food intake was one-fiftieth of his body weight, and as his body weight increased, the proportion of his body weight he consumed gradually decreased. So if the protagonist consumed two hundred tons, he would weigh over ten thousand tons—possibly even twenty thousand tons.)

By then, could the Giant's Evolution Energy—the energy carrying the evolution of limbs—allow the ten-thousand-ton protagonist to evolve limbs?

At most, he would probably grow a little bit.

How many Giants would he need to eat before he could evolve complete limbs after evolving other body parts? For the limbs alone, he would need around a hundred.

And just how small would those evolved limbs be relative to the protagonist's size?

So growing arms and legs by eating Giants would be difficult and not practically feasible.

Question: What was the Evolution Energy of Fish-Men?

Answer:

The Evolution Energy of ordinary Fish-Men, excluding Giant Fish-Men, allowed them to break through the size limits of human genes and reach three or four meters. It also contained their biological traits.

But they only surpassed the limits of their size by a small amount. Ordinary Fish-Men could only grow to three or four meters, so they had little Evolution Energy.

And they had too many traits—both fish traits and human traits. The protagonist possessed none of these, and their Evolution Energy was limited yet spread across many directions. The Evolution Energy for each individual trait was practically negligible.

Therefore, no matter how many ordinary Fish-Men the protagonist ate, he would be unable to grow organs.

Only by eating Giant Fish-Men could he grow body parts, with the spine and lungs taking priority.

Someone said in the comments for this chapter that this chapter was padded. I have no idea how your brain works. This isn't the main story—it was specifically written to explain comments and respond to reviews. How is that padding?
