Percy is a green saddle tank engine who loves playing jokes, and runs the Ffarquhar branch line with Thomas, Toby, Mavis, and Daisy, (formerly) and is the number 6 engine on the North Western Railway.
Percy was built in 1900 and worked on the Great Western Railway until 1933. It is possible he was so cheeky his controller put him up for sale. in 1949, The Fat Controller came over when Gordon, Henry, and James were on strike, and was desperate for another engine. He chose Percy and brought him back to Sodor, where he helped Thomas and Edward. He worked on the branch line while Thomas and Edward were taking care of the mainline trains as the other three engines were shut up in their sheds. Sometime later, he was waiting on the main line for the signalman to switch the points. However, he had forgotten to whistle to alert the signalman, and Gordon suddenly came down on the same track. Percy barely missed an accident and was so frightened that he reversed backwards without his driver. He kept on going all the way to Lower Suddery before he was stopped by a bank of Earth. Afterwords, Percy became a station pilot and goods engine until 1955, when the Fat Controller decided to buy a bigger, heavier engine to do the work while Percy went to the Ffarquhar Branch. This engine was a 5700 GWR pannier tank engine named Duck, and it was with him that Percy finally got revenge on the bigger engines for ordering him about. Duck sat on the turntable, refusing to let the other engines in, claiming he did not have the Fat Controller's permission to do so. After the incident was sorted out, Percy became part of the Ffarqhuar Branch Line.
Percy's first few months working on the Ffarquhar Branch were quite eventful, from a race to Harold to braving a flood to help Thomas. Around this time, Percy would take stone trains to Barrow. There, he met up with British Railway engines whom Percy became good friends with. He later passed a danger sign at Elsbridge Harbor and went in the water.
In the winter of 1959/60, He, Henry, Gordon and James feared that Donald and Douglas were to be sent back to the mainland after trouble had started up when they arrived on Sodor a few months prior. Percy decided to talk to Edward about the situation, whom explained to the former about a "deputation". Percy tells the engines about this idea and is chosen to be said deputation. After The Fat Controller returned, Percy talked him into keeping the twins on Sodor. After Thomas came to breakfast at the Ffarquhar's Stationmaster's House, a diesel railcar named Daisy arrived to do his work while Thomas had to go in for repairs. However, she was very lazy until Percy crashed into a brake van and the Fat Controller gave her a second chance.
In A Wretched Day for Henry and James, SI3D's 2009 model of Percy was used. At the time, he was only original NWR 6 character not to have the upgrade. From Episode II until the fifth season, his 2010 model was used. Since Highly Sprung, a model by Sodor Workshops is used.
Percy is a GWR Avonside 0-4-0ST, particularly based on GWR 1340 Trojan with the bunker of a GWR 1361.

- Aside from Duck obviously, Percy is the only name from the NWR 11 that T1E2H3 has yet to meet someone with it. However, his great grandfather was called Percy.
- It was through Percy that T1E2H3 learned many advanced words, such deputation, dignified, and celebrity.
