I have a theory!!! At the current time in pokemon planet, we have kanto, johto and a small bit of hoenn. It is planned to complete hoenn and then add Sinoh. At the current time in pokemon planet we cannot nickname pokemon. In pokemon diamond and pearl, the way you nicknames pokemon was to talk to a certain person. Diamond and Pearl was set in the Sinnoh region. I believe that in the near future, in pokemon planet, the way o nickname pokemon will be in the sinnoh region. But thats just a theory, a Pokemon Theory! Thanks for reading!!
