Diesel (Thomas & Friends)

&nbsp Diesel is known by everbody as, one of the main villains of Thomas the Tank Engine & Friends. As a villain, he is oily, malicious, devious, scheming and full of ideas to get revenge. But from Season 14 and onwards, Diesel shows he too, actually has a good side in him, but one would still have to look deep to find it. He wants to try and prove himself really useful, but instead, he acts like a kindergarden bull, and still hates steam engines, much to an annoyance to Thomas fans. It is possible Diesel is a permanent member of Sodor.
