For example, smogon tier, etc etc etc
Ok, well the tiers that people battle in are:
There's one unofficial tier called PU (A bit like NeverEverUsed). The Pokemon that have less than 3.14% of usage in NU go there.
Also, Pokemon Online, Neoseeker make their own tiers.
I think that there are only tiers created by Smogon. There also are tiers created by serebii, Pokemon online, and neoseeker.

If you combine them all, it would be(I think):
1 Uber 2 Standards (OU) 3 Borderline (BL) 4 Underused (UU) 5 Borderline 2 (BL2} 6 Rarelyused (RU) 7 Never Used (NU) 8 Not Fully Evolved (NFE)
