Notable Biology

Rattata are one of the most determined pests of the Kanto and Johto regions—a small purple rodent that it is nigh-impossible to be rid of. A Rattata's most prominent feature is the large, gnawing teeth. These teeth never stop growing, and thus Rattata spend much of their life chewing on tough objects in order to wear them down. This often includes wood and tough foods, but a determined Rattata can chew its way through stone. Obscenely common, Rattata also comprise a good percentage of the diets of other creatures of the Kanto reigon, especially Pidgeotto and Pidgeot.

A fully grown Raticate is truly a force to be reckoned with. Large, aggressive, and powerful, Raticate are very popular amongst the casual Trainer community, who value them for their speed, agility, and battle prowess. In addition, they are quite easy to obtain, evolving from one of the most common creatures in the area.


Rattata and Raticate can live most anywhere, as they can digest most foods without difficulty.


Rattata will resort to active hunting for prey when their typical diet of nuts and seeds run scarce—on his trip to Kanto, Professor Rowan once witnessed a determined group of Rattata attacking and killing a baby Bulbasaur. Raticate, being carnivorous, will hunt and kill most anything, and have even been seen eating other Rattata.


Rattata are not difficult to take care of—they are small and the only real danger for a careful human is the occasional bite. Raticate, however, are much larger, and as such pose a greater threat. Their bites can easily puncture skin and cause severe wounds. Reports of small unsupervised children being attacked by wild Raticate are very common in the Kanto reigon. In addition to this, many carry diseases that may infect an unwitting Trainer.

Courting and Childrearing

Rattata are one of the few Pokémon that can enter sexual maturity before evolving. A Rattata will gain the ability to reproduce as early as at ten months. As such, Rattata spend much of their lives mating and gestating. They breed all year round, and an average litter consists of 12-20 babies.

Social Structure

Rattata and Raticate live in large clans of up to thirty in the wild. In urban areas, hundreds may live in a relatively small area; bolstered by a stable source of food, their numbers swell rapidly.
