Diesel 10 made his debut in Thomas and the Magic Railroad in 2000, the first Thomas the Tank Engine feature film, where actor Neil Crone voiced him as the main antagonist. Nicknamed for his hydraulic claw Pinchy, he was created as a bigger, scarier threat than the usual cheeky diesels. Clips of the character later circulated through Thomas fan edits and YouTube compilations, and his theatrical laugh became a handy shorthand for cartoon villainy. It remains popular with nostalgic fans who grew up with the film and now reuse it in memes.
