EDIT: When I say "mature" I'm not talking about making Pokemon a dark, gritty, grey palette mess. I'm talking about how within the games itself Gamefreak has left dialogue, scenarios, and events that hint at the more darker underpinnings of the Pokemon world that you won't discover if you just play through the game like any other regular kid.
This is one of those times where reading what the OP posted below the title is really imperative to understanding what this thread is about :/
One of the things I've been thinking lately is how Pokemon is often labeled as a children's game and how there is no mature content in it for the older fans.
There is no denying that the target demographic of the franchise are kids. However the more I dig deep into the characters, dialogues, pokedex entries and various NPCs the more I start to notice that Gamefreak has been putting mature themes into the franchise. It's just done in a way that the average kid won't notice (and subsequently oversensitive parents won't flip their shit about.) yet enough that one can piece together some rather dark plots.
Here are some speculations that most of the adult demographic of the fandom agree on or for the most part deem that it could make some sense.
-In the pokedex entries revolving in Pokemon Silver it states that Gengar feasts upon the life force of it's victims. However in order for it to do so without being caught it hides in the shadows of it's victims waiting for the perfect opportunity. The only way to tell if a Gengar is nearby is if the temperature suddenly drops.
Knowing this information you can go back to the Red/Blue/Green versions(and their remakes) and think about the scenario with the haunted mansion.
The place is abandoned. However there are still many things lying about. It's clear that the inhabitants never actually left, and the gym leader warns you about the dangers in there.
When you walk in you will often see the ghost girl leading you around until you eventually run into the Gengar hiding in the painting.
Many have concluded that the Gengar lurking in the painting played a great hand in killing the inhabitants one by one. It would follow their shadows and slowly but surely drain them of their life force until they died.
The ghost girl is assumed to be the Pokemon's final victim before the rest of the inhabitants left.
Also the fact that she intentionally leads you to the room where she supposedly dies means that either A) She believed you would have the power to rid the house of Gengar or B) Had the intention of seeing you get killed at the hands of Gengar.
Of course in the game itself that wouldn't happen. On the outside this is simply an opportunity to acquire a Pokemon that you could only get through training. However I noticed that the red eyes never show up until you turn your back to it. Sure you have your Pokemon to protect you, however what's the point if the Pokemon gets you before you can so much as activate the ball?
On top of that, Gengar are not only fast, but powerful, so it can quickly end you before you had the chance to retaliate.
In the real Pokemon world- not the game, this Pokemon would be a whole lot more dangerous to meet. Yet alone catch.
In fact- based on all the dex entries revolving around Pokemon, Ghost Pokemon as a whole would be the most dangerous to humans.
- In Pokemon Diamond/Pearl if you go to the library in Canalave City you will notice that you can read a bunch of book in the upper floors.
There was an interesting folklore revolving around Pokemon and Humans:
There once were Pokémon that
became very close to humans.
There once were humans and Pokémon
that ate together at the same table.
It was a time when there existed no
differences to distinguish the two.
Then you get to another story and it goes like this:
A young man, callow and foolish in
innocence, came to own a sword.
With it, he smote Pokémon, which gave
sustenance, with carefree abandon.
Those not taken as food, he
discarded, with no afterthought.
The following year, no Pokémon
appeared. Larders grew bare.
The young man, seeking the missing
Pokémon, journeyed afar.
Long did he search. And far and wide,
too, until one he did find.
Asked he, "Why do you hide?"
To which the Pokémon replied...
"If you bear your sword to bring
harm upon us, with claws and
fangs, we will exact a toll.
"From your kind we will take our
toll, for it must be done.
"Done it must be to guard ourselves
and for it, I apologize."
To the skies, the young man shouted
his dismay.
"In having found the sword, I have
lost so much.
"Gorged with power, I grew blind
to Pokémon being alive.
"I will never fall savage again.
This sword I denounce and forsake.
"I plead for forgiveness,
for I was but a fool."
So saying, the young man hurled the
sword to the ground, snapping it.
Seeing this, the Pokémon disappeared
to a place beyond seeing...
Not only does this confirm definitely that Humans do eat Pokemon as a food source, but it basically explains the reason why Pokemon attack you out of the grass for seemingly no reason at all.
Which is basically summed up by a kid who was so bloodthirsty and had so much disregard for life he went around killing slaughtering Pokemon for the fun of it until they no longer showed themselves to the naked eye.
Last thing I want to talk about because this post is getting so long is the whole mythology itself.
Yeah we know. There are a whole bunch of legionaries. Each one representing a myth or legend on a variety of cultures.
The question is however, do those legendaries only exist because the people in game believe them?
The most underrated of all the legendary Pokemon in the game are the Unknown. However, it is the most powerful legendary in terms of what it can do in game.
In the movie it is stated that the Unknown can basically take the dreams and wishes of anyone and make it become a reality.
In the case of the little girl she missed her father greatly who had disappeared so suddenly years ago. The one thing she remembered most about her father was that he would act like an Entei.
So the Unknown that were there at the time basically created an Entei for her because she wished it so.
Also consider the fact that the Unknown have basically been present in every Pokemon region except the Sinnoh region.
When you obtain Arceus in Diamond and Pearl and do the Palkia/Dialga, and Giratina event despite Cynthia saying that Arceus can create the other three legendaries, the players are surrounded by Unknown.
Which made many wonder- did that particular Arceus create Palkia, Dialga, and Giratina?
Or was it really the Unknown that did all the work?
Another thing is that are the only reasons why the other legendaries exist simply because the people of the regions believed them so much that the Unknown created those Pokemon to validate their own beliefs?
The only other Pokemon close to being able to do what the Unknown can is Jirachi, and even that was flawed at best.
Jirachi- based on the movie- while it was able to create a Groudon, one could tell it was never a true Groudon.
It was flawed. A slimey, corrupted imitation of the real thing that was easily destroyed if the Pokemon wished it.
Knowing that, which Legendary Pokemon are not just dreams become reality, and which ones actually used to exist at some point?
We all know Pokemon like Mewtwo definitely exist. He was man made.
Likewise Deoxys is real as well. Seeing as how nobody knew of it's existence nor did they ever have a belief to validate it so there would be no reason for the Unknown to create it.
Like I said, there is so much more I want to put in this post. However it is now a tad bit too long.
I also find a very interesting theory on the "industrial revolution" version of Pokemon on my dashboard.
However I think that should be a topic for a different thread.
