Rattata is a small, quadruped rodent Pokémon. Its most notable feature is its large teeth. Like most rodents, its teeth grow continuously throughout its life and must be worn down by gnawing. Rattata has purple fur on its back, and cream fur on its stomach. It has a pair of thin, cream-colored whiskers and a long tail that curls at the tip. Females have shorter whiskers and lighter fur color.
Rattata can live wherever it can find food, which it searches for most of the day. Thanks to its sharp fangs, it is able to eat nearly anything. When it is threatened, Rattata can deliver a powerful bite. Its large teeth are also useful when using its former signature moves, Hyper Fang and Super Fang. Its hardiness lets it live in many environments, although it mainly lives on plains and savannas. Because it reproduces so quickly, a pair of Rattata can quickly colonize an area.
The Rattata population in Alola was booming until Yungoos was imported as a control measure. In order to avoid these new predators, Rattata altered its habits. It moved to more urban areas, became nocturnal, and formed large nests led by Raticate. Alolan Rattata search out fresh food by smell, and ignore anything spoiled.[1] It has dark gray fur and grayish-purple ear insides. There are two tufts of fur on each ear and near the tip of its tail. Its long, thin whiskers are replaced by shorter, thicker tufts of fur as well. The line where its cream underbelly meets its gray fur is ragged instead of smooth.
Rattata debuted in Pokémon - I Choose You!, where it was trying to steal food from Ash's backpack. After Ash realized this and chased it off, it hissed at him before continuing to run away.
Multiple Rattata appeared in Leading a Stray!, where they were among the Pokémon assisting a Luxio in its efforts to help a Wailmer trapped in the sewers.
A Rattata appeared in Johto Photo Finish, where it was one of the Pokémon being fed by Tracey at Professor Oak's Laboratory.
Three Rattata appeared in Hoenn Alone!, where they were among the Pokémon that were having trouble with the Haunter from the area they lived in. Pikachu and Meowth managed to drive the Haunter away.
Rattata and its evolved form, Raticate. The Mouse Pokémon. A Dark and Normal type. When they band together, they steal food from people's homes. Long ago, they came here to the Alolan islands aboard cargo ships, and eventually grew into the Pokémon we see today. The numbers of Rattata and Raticate eventually grew so large that Yungoos and Gumshoos were brought in from a different region to chase them off.
In Off Course with Corsola, Bill fantasized about two Rattata, one from the Kanto region and the other from Johto, when he explains to Crystal that Pokémon from different regions can have different colors, patterns, and features.
Rattata is cautious in the extreme. Even while it is asleep, it constantly listens by moving its ears around. It is not picky about where it lives - it will make its nest anywhere.

They also all have at least one family member with a regional variant in Alola.
Rattata has gained notoriety among the fanbase due to YoungsterJoey on Route 30, and his phone calls claiming his Rattata to be within the top percentage of the species.
Rattata has the lowest base HP of all Normal-type Pokémon.
Alolan Rattata can be seen as a counterpart of Yungoos as they can be caught at certain times of the day (Yungoos at day, Alolan Rattata at night). They also evolve into Gumshoos and Alolan Raticate, respectively, at level 20 at their respective times. Also, their evolved forms are the Totem Pokémon in their respective games (Gumshoos in Sun and Ultra Sun, Raticate in Moon and Ultra Moon).
Origin
Rattata is based on a rat. The shape and position of its ears might be derived from the dumbo rat.
Alolan Rattata may be based on how Hawaiian rats tend to be more vicious than most other areas of the world, which would explain its Dark typing. Their regular attacks on sugar cane fields forced the locals to import the mongoose, explaining the relationship between Yungoos and Rattata.
Name origin
Rattata may be a combination of rat and attack, evident from its prototype name, Rattatak.[2] It may also incorporate the onomatopoeic word rat-a-tat.
Koratta is a combination of 子 ko (child) and Ratta (Raticate's Japanese name), leaning toward the meaning "child Ratta." It may also be a combination of 小 ko (small) and rat.
