Spencer

Spencer is a sleek streamlined engine privately owned by The Duke and Duchess of Boxford. He commonly visits the Island of Sodor with his owners.

Personality
Spencer is very arrogant, snobby, egotistical, bossy and pompous and considers himself to be above doing menial duties such as shunting. He is very proud of his speed. None of the engines particularly like him, especially Thomas and Gordon. When he came to build the summer house, Spencer proved himself to be very nosy, sneaky, disobedient and rather neglectful. Gordon and Spencer do not get on very well with each other. This is mainly because of Spencer's pompous behaviour, which exceeds even that of Gordon's. His arrogance has also shown that he is not willing to take advice from other engines, which only results in him needing help from those he shrugs off. Despite this, he has shown a kind side when he realised his mistakes, especially when reprimanded by the Duke and Duchess or Sir Topham Hatt for causing trouble. This side once came through when he saved his brother, Mallard from sinking in the ocean. Despite his pompousness, he also wants to be really useful just like all the other engines.

Trivia

 * Spencer has had modifications throughout the SC Shorts. These include:
 * In "The Gay Race", he gained white dots on his pupils.
 * In "This Has Nothing To Do With Halloween", he gained a painted whistle in front of his funnel and the back of his cab was painted black.
 * In "Thomas's Epic Thanksgiving Special Part 1", Spencer gained front windows, handrails on either side of his cab entrances and tender, a handrail on the rear of his tender, removed valences, and his handrails on the side of his boiler were repainted silver.
 * In "The Little Red Stalker", his Learning Curve Wooden Railway model was replaced with a Talking Trackmaster model of Spencer with added paper head lamps, painted tail lamp, front cab windows, silver coupling, and silver tender boogies. His model also had its voice chip and motor removed.
 * Starting from "The Little Red Stalker" onwards, the voice that Sammy Clark now provides for Spencer is based off of Glenn Wrage's voice in the US dub of Thomas & Friends.
