Editing Percy (section)

==Personality==
Percy is a rather cheeky, but kind engine. He normally behaves well, yet he also gets himself in trouble by jumping into situations without adequately thinking them through first. He loves teasing other engines, especially bigger ones such as Gordon and James, but is always brought down to earth in due course by anyone who gives him the moral to learn, especially the Fat Controller. He can also be somewhat timid.

Percy can also be questionable and naive to certain difficult words: he would say "dingy-fried" whereas anyone else would say "dignified", "dimmer-station" instead of "demonstration", "inspectacles" instead of "inspector", etc.

Percy is incredibly accident-prone and has many accidents, sometimes due to his own silliness or his tricks backfiring. He holds the dubious record of the most accidents in one series - five; all of which happened in the second series - crashing into some buffers, falling into the sea, being pushed onto a brake van, colliding with a cart of lime and being hit by a falling crate of treacle. His silliest accident to date, however, was in the sixth series, when he slipped on oily rails and crashed through the chocolate factory and emerged covered in chocolate. Despite this, he always tries to do his best, learns from his mistakes and get his jobs done, a loyalty which Sir Topham Hatt has praised him for on many occasions.

Although their friendship has been turbulent at times, Thomas is Percy's best friend. He is also good friends with Toby. While he has a small rivalry with Harold stemming from their race, they are always willing to help each other when in trouble.

Percy can also be seen as an easy target for teasing by the big engines, especially whenever he has an accident or when he is afraid of something. He also has held a grudge from them about their tricking him into misinterpreting a signal but silenced this with some help from Duck. This shows that, when nonsense goes too far, Percy will not stand for it and seek help to settle the matter for good, even if he faces a reprimanding from Sir Topham Hatt for it.

During the CGI series, Percy became wiser, and a little less cheekier. This could be because he learnt his lesson for being cheeky or because he didn't want get in trouble again. In the CGI series, Percy and Thomas' friendship expanded and they hardly ever argued.
