What generation is PRO based off of. Ex; X&Y or Diamond and pearl or what.?

[Iskq]

Just curious if it's based on diamond and pearl or if it's based off of x and y. For example, if I were to go to smogun to look up, let's say, a slowbro. What would I look under? I'm assuming diamond and pearl?

I think it's generation VI. But don't quote me, I'm not sure. I would like to know it too.

So far there is the first two regions, but pokemon from all 6. Typing and battle rules are gen 6, move sets are gen 6 for pokemon 1-200 and gen 6. Otherwise its gen 5. Its gen 4 art style in game, and 3-4 overworld art style.
