I think that the real world could never completley become the Pokemon world. The Pokemon world that we percieve mostly resembles the one in the anime world (as the games for me is not realistic enough.) If the real world was to become like the one in the Pokemon anime world, then a lot of problems would occur.
Firstly, how would we know if the Pokemon are our friends or enemies? Obviously you would think that most people would want to befriend them but what about the not-so-friendly Pokemon lurking around. I mean really, what would your reaction be like if you found yourslef face to face with a Charizard. I, personally, would try and run but, noting the fact that it has two huge wings, I probably wouldn't get far. This means that most people would deem Pokemon as killers and most likely humans would be segregated from them. I mean, seriously, would you want your eleven year old child venturing out on a journey full of dangerous creatures that could kill them with one swipe?
Next comes the fact of rules. Yes, we have rules in the real world. So many rules occur to make sure that we live our life safely and hassle free. This means that the humans would become first priority and most "dangerous" Pokemon would either be caught and kept in zoos or worse. Rules would also affect the way humans keep Pokemon. No way would environmentalists suffice for humans keeping Pokemon in Pokeballs (even if they do get turned into smaller versions.) There would be protests, rallies and general annoyance to the government until they give in and keeping Pokemon in Pokeballs are banned.
A lot of these things would ruin and possibly endanger Pokemon if they were to come to our world. So, I say this to you, little Pocket Mosters. Stay in the Pokemon world. You are safe there.
