1st off, we've got a 4channer above me.
2nd off, yes there are lots of beta rumors.
The one that interests me the most is the Parasect Creepypasta. To be honest, it was a Pokemon I overlooked until I heard the rumor. You can probably Google it, but here is the gyst of the story:
Parasect is controlled by the Mushroom on it's back (says so in the Pokedex entry). In fact, Parasect is really a "zombie" if you will. It's lifespan is depressing. It lives, mates, lays eggs, then dies as the mushroom spores onto the Paras eggs, burrowing the parasitic Mushroom into the body before it is even born. It's really sad. The moment Paras evolves, it becomes unconscious of anything it does. Later the mushroom tells it to mate, then kills it, growing out of it's hollow shell (this is assumed). The creepypasta claims that when asked about the rather creepy Pokemon and it's strange hollow eyes, Satoshi Tajiri became nervous and sweaty. When asked any further he would simply yell "PARASECT IS A POKEMON AND NOTHING MORE!! STOP OVERTHINKING IT!!". But people found this to even more disturbing. Some choose to believe that maybe Satoshi is trying to warn us of something. For example, where do Parasect live? Mt. Moon. Also home of a Pokemon thought to be an alien (Clefairy). And it's even more of a coincedence that Clefairy was originally slated to be the mascot of Pokemon before Pikachu. And if that isn't crazy enough consider this: Satoshi Tajiri collected bugs as a child, primarily cicadas and beetles. If you look at Paras you will see the striking resemblance to a cicada.
Now I'm not quite sure I believe this, after all it is just a Creepypasta. But Paras and Parasect are based off of a real phenomena in South America, where a Mushroom (I forgot the name) will spore onto ants and will release halucinogens into the ants mind to tell it where to go. So there is a bit of truth behind these Pokemon.
Anyways, TL : DR, a strange story saying that Parasects are warnings of aliens controlling us with mushrooms.
