Several outlets have published rankings of powerful pokémon, with some focusing on legendary pokémon and others on various categories such as strongest trainers, rarest pokémon, and non-legendary types. The rankings appear to vary in scope and criteria, with some listing as few as 10 pokémon and others listing up to 35 or 20. The different rankings suggest that there are multiple ways to evaluate the strength and value of pokémon in the anime series.
