In the original versions of Pokemon Red and Green versions (or blue) there have been quite a few rumors and conspiracies for years.
Here are the ones I think are interesting and would've wanted to see happen in the game:
Kangaskhan is Cubone's dead mother and a baby Kangaskhan is a Cubone and that's what skull it wears on its head. There was originally going to be a code for Marowak to evolve into kangaskhan, but at the last minute they put the code in a different spot because they had no time to remove it. Ya know, I wonder why did they remove it? It would've been cool to see that. So MISSIGNO. is the code they put in Cinnibar Island after you talked to the old man in Viridian city and flew there you would encounter it. I seriously wonder why they didn't just make Marowak evolve into Kangaskhan.

Metapod was going to evolve ino Venomoth and Venonat was going to evolve into Butterfree. Again, I sriously wonder what was wrong with this because Venomth looks more like Caterpie and Venonat looks more like Butterfree.

Gengar is a dead Clefairy. Makes sense, but not confirmed.

The original theme for Lavender Town in the Japanese version of Red/Green was at a higher pitch than the US version (I don't see a difference) that made many japanese kids commit suicide. This is called Lavender town Syndrome.

Gary's Raticate from Yellow died in the Lavender tower
What are your thoughts/opinions of these and what are some other ones you have found? Discuss!

As for the Caterpie/Venonat conspiracy, I think it may connect to the anime. If they intended for Ash to catch a Caterpie, it would have to evolve into Venomoth, which isn't the most lovable-looking Pokemon. They couldn't have Ash catch a Venonat either, since Venonat isn't available that early. As such, a simple evolutionary change could fix everything!

Makes sense.

Where'd you get the troll face?

I don't think any of those evolutionary things have actually been confirmed. THey're interesting theories, but nothing more, I don't think. Same with Gengar and Gary's Raticate, but Lavender Town Syndrome? That's just a bunch of nonsense.

I heard all these rumors except the ones about the Butterfree and Venomth, but yeah o_o Venonat looks a lot more like Buttterfree.

I listened to the Lavender Town music carefully. the tunes are long and pretty loud and there's a part where the tune raises in pitch. If I take that same tune and give it a db gain of +9 or +12, that should be enough to rape a little one's ears. Plus sound distortion is never good to the ears, so yeah that Lavender Town Syndrome might be true.

I belive the part on metapod into venomoth. Why didn't they do it? it would have been better and alot more scence.

I've heard about the higher pitched Lavender Town theme.

The Lavender Town Syndrome one scares the HELL out of me

The Lavender Town thing is easily false, remember this is the same country that has banned porygon from every episode of pokemon and refused to air the Team Rocket specials because of an earthquake.

The music lavender town consiry is fake, the music was replaced due to its erratic change's in frequency. not because it was causing death's
