Composition

PU is Smogon's fifth usage-based tier. All Pokémon that are not OU, UU, RU, or NU by usage and are not banned to Ubers, UUBL, RUBL, NUBL, or PUBL can be used in PU. While any of the aforementioned Pokémon can be used in PU, only those Pokémon that make up at least ~3.41% of total weighted usage in the tier are designated 'PU.' A Pokémon is truly 'PU' if a typical competitive player is more than 50% likely to encounter that Pokémon at least once in a given day of playing (20 battles).

A list of the current PU Pokémon and those with PU analyses for the SM era are found on the dex page.
