I just love the implications of a world collision type thing... how the environments would change, how species would react to each other, how hunters would react to pokemon, how trainers would react to Wyverns...

How things would be TYPED...

The thoughts of how the older-style Kingdom and Fleets would respond to the modern styles of the cities and the Pokemon league...

Pokemon professors going nuts over all these new critters would be so amazing... if there wasn't the problem of so many things having their territories invaded and going nuts because of it.

And god, Legendaries versus Elder Dragons would be amazing...

Fatalis versus Rayquaza most immediately coming to mind, but shit, ANY turf wars would be incredible.

And Meowths and Felynes getting along like WILDFIRE...
