Glad you like it. I put it in my adventure series too.

"Devious" Diesel, as his name implies, is a sinister diesel shunter, the main enemy of Thomas the Tank Engine and Twilight Sparkle (alongside Diesel 10)
 * Diesel 10 is two of the main villains in Thomas and Twilight Sparkle's Adventure Series alongside Devious Diesel just like in Thomas & Friends.
