Raticate

Raticate is a Normal-type Pokemon evolved from a Rattata. In the anime, Ash Ketchum briefly owned a Raticate after he traded it to a very rich man for his Butterfree while traveling on the St. Anne. After a short while, he traded his Butterfree back after missing all the good times he had with it from the time he raised it. Cassidy from Team Rocket also owns a Raticate.
