Gordon is the strongest engine on Sodor, and also one of the fastest. He has the number four and is the most recurring engine to pull the express, which Edward is the back engine for. He has a high and mighty attitude, which gives him an arrogant mind and a reluctance to work with smaller engines (mostly Thomas and Percy). Even so, he still has an iron will and will help out when needed. He once broke down on a hill, which was later named after him.
