Diesel 10 is another diesel train engine who is much larger than Devious Diesel, and probably even MORE evil than him, and that's saying something! Diesel 10 once tried to find some magic buffers that would supposedly find him a very legendary magic steam engine named Lady that would only come to life with the buffers and some special magic gold dust... And once Diesel 10 got his hands, or much rather, his claw (Which he named Pincy) on the special train, all of the steam engines would be history, and the steam train engine race would've been wiped from existence, leaving only the diesel engines standing tall. Fortunately, again, Diesel 10's plans ultimately go awry after both Lady and Thomas escape a broken bridge, leaving Diesel 10 to fall down on a barge below the bridge. Can Diesel 10 be able to leave his past behind in this character elimination, or will the thirst for vengeance get the better of him?

(For Diesel 10's voice, I'm looking for an evil-sounding male medium-pitched or mid-low-pitched adult voice. If you want to, you can try and replicate the previous Diesel 10 voices from existing sources in the Thomas and Friends franchise, but it's not required, and you can choose to come up with your own Diesel 10 voice with either an American accent or British accent instead.)
