Diesel 10 has been absented from the series The Missing Christmas Decorations because Mattel and the writers deemed him too scary. Well, we need to have them understand that Diesel 10 is not too scary for us Thomas fans and persuade them to have Diesel 10 appear in the series again and continue to be the diesel villain we all know he is from his debut and onward like in specials and four episodes, not to mention get them to give Diesel 10 his original personality from Thomas and the Magic Railroad back and add more like bring malevolent, likes causing destruction, hatred for steam engines more passionate and have his description included too so if you sign here and get Mattel and the writers to understand that Diesel 10 is not too scary for us, we'II be able to get them to return Diesel 10 to screen once and for all. Hopefully Micheal White will help with returning him too since he's a fan of the show and now writer of it. Good luck.
