>>44387055>UUSlightly worse versions of OU mons that are strictly outclassed and that can UU can handle, which slowly made UU be Diet OU in a way. If they're not directly outclassed, chances are they can carve out a niche in OU
>RUPokémon unfit for the UU Meta can end up there, but still be reasonably good and the best of their kind at a specific niche. For some reason, a lot of bulky offense, and sometimes stall mons, usually end up there, but are quite solid in OU. Alomomola, Rhyperior, Tangrowth, Reuniclus were all RU mons at some point.
>NUPoint of no return outside of very specific niches: RU isn't as rough and is less niche reliant. If a Pokémo ends up NU, it's in the definite lower end of viability, or an exception.
>PU Slightly worse than NU, but actually not by
much.It's kind of the UU of OU. Still just shitmons outclassed by shitmons
>ZUIredeemable
