Like polteaghiest's roots are tea and polterghiest but its not there soo....
Actually that has always been my intention, just lacked a bit of time recently. I had done the starters but nothing since. But I've just spent a bit of time updating the origins for all the new Pokemon!
You are welcome to post any of the origins for any new Pokemon as they are revealed, in the name origins corrections thread - might save me some time when I come to do them. And of course suggest corrections for the ones I've done, if I've missed anything.
