Pokémon RPG centers around a group of fantasy creatures known as Pokémon, from which the series itself takes its name. A group of humans known as Pokémon Trainers catch Pokémon and train them to battle other Pokémon for sport and/or as loyal companions, with their main goal is to become the Pokémon Champion while preventing a wicked group of Trainers, known as Villainous Teams, from causing danger to the world. Known regions include: Kanto, Johto, Hoenn, Sinnoh, Unova, Kalos, Alola, Galar, and Paldea. Pokémon, shortened from Pocket Monsters, are a group of fantastical monsters who are the central focus and main feature of the Pokémon franchise. Pokémon are found all over the Pokémon World, and their habitat varies depending on the species, much like creatures in the real world. There are currently 1,025 documented species of Pokémon based on the nine generations of games so far as of Pokémon Scarlet and Pokémon Violet (with more yet to be discovered as always). On the franchise's debut with Pocket Monsters Red and Pocket Monsters Green (or Pokémon Red Version and Pokémon Blue Version), however, there were only 151. One particular Pokémon, Pikachu, is the series' main mascot. Pokémon take from a wide variety of inspirations including animals, plants, mythological creatures, and objects. Rattata resembles a rat, while most others take more unusual forms, such as Exeggutor, which resembles a coconut tree with animal facial features and feet. Although most Pokémon look and act like animals, others share no resemblance to any of such creatures, plants, or fungi, and a few even have machine-like forms, such as Registeel. Some Pokémon even resemble humans, such as Mr. Mime and Jynx. The most powerful types of Pokémon are Legendary Pokémon and Mythical Pokémon such as Lugia or Jirachi, who are usually the subject of myths and urban legends within the Pokémon World. Each Pokémon has an elemental type, which affects their attacks, abilities, and weaknesses. For example, Pikachu, being an Electric Pokémon, specializes in electrical attacks, which are effective against both Flying and Water Pokémon, but in turn are weak against Grass Pokémon and ineffective against Ground Pokémon. Each Pokémon has unique stats and characteristics. For example, Darkrai is very fast and strong but has mediocre defensive ability. Most Pokémon have their own evolutions, which are different Pokémon that they can evolve into once certain requirements have been met, making themselves grow into a more mature and powerful shape. For example, a Ralts can evolve into Kirlia, and Kirlia can evolve into Gardevoir at level 30, or give a Dawn Stone to a male Kirlia to evolve it to Gallade. One certain Pokémon, Eevee, can evolve into as many as eight different ways. In most games, it is recommended to have Pokémon evolve to defeat Gym Leaders or stronger Trainers more easily. Legendary and Mythical Pokémon, however, almost never evolve (excluding Mega Evolutions). The relationship between a Pokémon and a human varies, depending on the species and personality. In the Pokémon World, several humans become Pokémon Trainers, who capture Pokémon using a Poké Ball to then keep them as a traditional pet and/or to have them engage in Pokémon battles. Many Pokémon Trainers go on an adventure with the goal of capturing every known species of Pokémon, and they take a Pokédex with them to catalog each's Pokémon's data, as well as becoming the Pokémon Champion of their own specific region. One unique way in which Pokémon are grouped is by generation. The Pokémon franchise started off with 151 Pokémon during the first generation. A generation usually begins when new Pokémon are introduced, such as when 100 Pokémon were introduced in the Generation II titles, Pokémon Gold Version and Pokémon Silver Version, raising the total number of Pokémon at the time to 251, and so on. Unlike real-world animals, Pokémon naturally possess powerful magical abilities (usually elemental) which they can use to perform a task (such as battling) or defend themselves or their Trainers from harm, though they can fight physically if necessary (especially true with Fighting-types). In comparison, the creatures are also significantly more anthropomorphic in nature - displaying high levels of intelligence, express strong emotions, and are extremely social like that of humans; They are even smart enough to build home structures suitable for themselves and live independently, solve puzzles, produce food or operate machinery in some cases, though they sometimes still rely on people for assistance and vice versa. Although Pokémon usually can speak only one word - their own names, or in some cases simply grunt or roar (such as Charizard), they fully understand human language; Certain Pokémon do indeed speak in full sentences, as most often in the cases of Legendary and Mythical Pokémon (through telepathy and rarely actually talking). Due to this complex level of nature, Pokémon are generally deemed dangerous by humans and rightfully so, especially if a Trainer attempts to enter tall grass without having trained Pokémon of their own for personal protection against wild ones, even for experts. Despite their potentially deadly powers and are their propensity for combat, as revealed in the games and other media within the franchise (anime, manga, etc.), due to it is also part of its central theme, all Pokémon, including Legendaries and Mythicals, can be befriended, as the creatures themselves under normal circumstances are known to be pure-hearted, view humans as friends, and clearly wanted to have a close bond with their Trainers, which is more often displayed in the core series with first partner Pokémon. In such good cases, they will grow to love and even become affectionate to them. However, though most people in the Pokémon World use Pokémon the right way as loyal companions, there are others who use them wrongly. Such foul Trainers and their leaders often steal or treat Pokémon, usually Legendaries, as tools of war for global domination or money. Expectedly, Pokémon dislike mistreatment or disrespect, and in severe cases, they will have intense fear or anger toward that Trainer and may attack in retaliation.
