Pokémon (JP) (a portmanteau of "Pocket Monsters" (JP)) referred to the creatures that can be obtained in the highly successful Pokémon franchise. Currently, there are a total of 905 identified types of Pokémon species, with about 100 or so new ones being introduced with each new generation, or series of the games. In the first generation, which consisted of Pokémon Red and Blue, and the counterpart Pokémon Yellow, there were a total of 151 Pokémon.

Each Pokémon is categorized into a multitude of traits, including their type, color, weight, height, and so forth. Most Pokémon can evolve into a more powerful species by leveling up, sort of like how a character in a traditional RPG can change into a more powerful level.

Pokémon in the anime, have been shown to only be able to speak their name or a variation of it, excluding a select few who are capable of human speech (example - Meowth). Others, such as Mewtwo and the popular Lucario can speak telepathically, but not directly to a human.

Variation within species

Gender Variation

There are a number of Pokémon with differences between genders. Most of these are some small differences, but some of these a are completely separate species of Pokémon like Tauros and Miltank. Gender variation was not introduced until the fourth generation. Oddly, after the fourth generation, the amount of gender differences has greatly decreased but, the degree of difference of these Pokémon are much larger than the majority of them. There are certain Pokémon that are the same species but, have different movesets depending on the gender.

Some Pokémon can only evolve if they are a certain gender.

Environmental Variations

Introduced in the seventh generation, certain Pokémon have regional differences based the region they are found in. These regional variants have developed differently based on the environment with most changing type, ability and can even evolve into completely separate Pokémon.

Some Pokémon have some physical variation based on the local environment they are found in. These Pokémon include Shellos, Gastrodon, Burmy, WormadamFlabébé, Floette, and Florges.

The Pokemon are stronger than their normal forms and often change many features, abilities and their form. After a battle finishes, they return to their normal form. This was introduced in Generation 6 with Pokémon X and Y.
