Pokémon are ranked under the following five factors:
Pokémon in higher ranks, such as S and A, are considered very efficient, while those in lower tiers, such as D and E, are considered not very efficient. The major factor under which each is ranked is efficiency a Pokémon that is efficient provides faster and easier solutions to major battles, which include Gym Leaders, Elite Four members, and N and Ghetsis at the Pokémon League, than ones that are inefficient.
