Flynn is a "really red fire engine" who fights fires on Sodor and is part of the Sodor Search and Rescue team. He has both tyres and flanged wheels, meaning that he is capable of running on roads and on rails. Flynn is fast, fearless, and ready to fight any fire. He is popular with the engines and held in high regard all over Sodor, but his overly-enthusiastic bravado can lead to not listening to instructions amidst his racing about and result in him making mistakes. He can also be self-conscious about maintaining his fire-fighting hero status. Nevertheless, Belle and the rest of the Search and Rescue team are often there to support him and keep him on course. And, at the end of the day, Flynn always has it in him to prove that he is always ready to rescue, and is a really useful hero.
