I. As a book focusing on nurturing Pokémon, it's inevitable to touch upon the topic of Pokémon egg hatching. While this hasn't been covered yet, it will be addressed later. The author would like to provide an explanation to readers and asks for understanding.
1. In the original story, the type of Pokémon hatched from eggs was determined by the mother. In this adaptation, it's modified to be randomly determined by either parent.
2. Pokémon without genders, which originally bred with Ditto in game, will now only breed within the same species. Although they don't have genders, the specifics of who gives birth are intentionally left unmentioned, both in the story and by the author, as having any Pokémon breed with Ditto would be unsettling in real life.
3. Even if the egg groups are the same, the author won't pair Pokémon with vastly different size characteristics for breeding. For instance, Even if both Wailord and Skitty are in the Field egg group, the author won't arrange for them to breed.
II. Additionally, there's a timing issue related to the appearance of Fairy-type Pokémon in the story.
While Fairy-type Pokémon were introduced in the XY generation and not in previous generations, this perception is due to the XY games being released later. In the Pokémon world, there's no official statement that the discovery of Fairy-type Pokémon occurred only after the protagonist arrived in the Kalos region.
Similar to how in the Pokémon anime, when Ash first encountered Fairy-type Pokémon upon arriving in the Kalos region, he expressed surprise with lines like, "Fairy type? I've never heard of this type before!"
Did Professor Oak ever express similar thoughts like, "Fairy type! An attribute I've never seen before, I need to research it"?
No, there's no evidence of this.
This implies that while the discovery of Fairy-type Pokémon might have been later, it certainly didn't happen after the protagonist was born. The protagonist's early unawareness is due to the incomplete understanding of the Pokémon world lore.
III. Lastly, regarding Pokémon aptitude in the story.
In the book, Pokémon aptitude is categorized into seven levels: Red, Orange, Yellow, Green, Blue, Indigo, and Purple. Red is the lowest, while Purple is the highest, with Green and above being considered high aptitude.
1. The occurrence rate mentioned for each color aptitude in the book refers to the wild Pokémon population. Breeding facilities have their own cultivation methods, leading to higher chances of high-aptitude Pokémon, and therefore, trainers are slightly more likely to encounter high-aptitude Pokémon.
2. Green aptitude Pokémon are the main contenders for various competitions in the book. Yellow and lower aptitude Pokémon are often used during transition periods by somewhat capable trainers (excluding average people). Strong trainers, such as Gym Leaders, mainly possess Pokémon with Green aptitude. Hence, having numerous Green aptitude Pokémon in the story doesn't warrant derogatory remarks.
Blue aptitude is rare, and the number of such Pokémon is scarce. Highly skilled trainers primarily possess Pokémon with blue aptitude. Examples include regional Champions and Elite Four members, as well as certain special Gym Leaders who might have one or two blur aptitude Pokémon. Notably, important supporting characters or Champions having blue aptitude Pokémon should not be dismissed as commonplace.
Additionally, the protagonist will have a relatively higher number of Pokémon with Blue aptitude. Well, he's the main character after all!
Indigo aptitude Pokémon are extremely rare. Only a few champion-level trainers would possess one or two as their aces. For example, Lance Dragonite, Wallace Milotic, Steven Metagross, Cynthia Garchomp, Diantha Gardevoir, and so on. Some important supporting characters might also have one or two, but the quantity is limited.
Purple aptitude is legendary in nature. It's rumored but unseen. Even champions don't have them (perhaps a few special individuals do, but they keep it hidden, and no one knows).
Lastly, the Legendary Pokémon aptitude is unknown and doesn't fall into any of the Red, Orange, Yellow, Green, Blue, Indigo, or Purple categories.
IV. About the Pokémon League in this work:
Many readers tend to unconsciously categorize the League negatively, but in this book, the League is an orderly organization.
While certain issues might exist within the League, it is primarily a just entity.
Hence, scenarios where the League would trouble the protagonist for treasures, Pokémon, energy cube formulas, or the like, due to various reasons, do not exist.
Regarding the League and the Three Pokémon Starter:
The League exercises strict control over their Three Pokémon Starter, with limited dissemination and nurturing methods. However, they do not prohibit other breeders from cultivating and selling the Three Pokémon Starter.
This can be likened to our nation state-owned enterprises possessing advanced technology. Naturally, they wouldn't share it with private enterprises. Yet, the nation doesn't forbid private enterprises from conducting their own research, right?
This principle applies here.
It's not just about the Three Pokémon Starter; this holds true for other aspects as well.
These are settings unique to this work and unrelated to other creations.
