Percy is a small engine who works on the NWR. He is one of the youngest engines and currently handles the good trains on the Ffarquhar branch with Thomas, Toby, Mavis and Daisy.
Percy was supposedly built by Avonside Engine Company, He first came to Sodor in 1935 when the Big Engines went on strike about extra work. Edward show him around, Percy learned very quickly as he worked and when Henry came out, He wheeshed steam at him cheekily, Henry jumped and went back to the sheds.
Percy soon found himself feeling overworked on the branchline and started to take his anger out on his friends.
Percy is kind, helpful and abit naive. He can also be quite cheeky but can still keep busy. He is close friends with Thomas, Toby, Duck and Oliver.
