Real quick question.
If you would use any hit era or cgi character in your series who would it be?
Ok, so this is an interesting question, and it's a hard one to answer because a number of the HiT and CGI characters are blank slates, I can press any characterization onto - so I'll run through a few I have considered for my ERS series:
Molly: she made it in! She's the only HiT era character who managed to sneak through the net, and that's because she's one of the few HiT era characters I felt had an interesting character (and design) and that gave me plenty to work with. You can read her spotlight book here.
Neville: I was sorely tempted when I was writing 'Searching for New Engines' to drop him in as a last-minute pickup. I even toyed with him replacing Emily in that particular book or being added with Murdoch. But I didn't in the end because I just didn't have much to say about Neville. I may change my mind and drop him in as a cameo, but otherwise don't expect him too soon.
Rosie: Rosie and I have a... turbulent history. I've never liked her as a character, and her CGI reboot never clicked with me either (it was the weird valentine's day thing). However, I did consider having her cameo at least once in 'Salty the Dockside Diesel Engine' due to her connection to both Salty and Thomas - her class somewhat replaced the E2's in Southampton, and then along came Salty and the 07s and replaced both.
Samson: he also made it in! Samson stars in one story, because he was built by the same company as Neil and has a similar shape, making it feel like he could have also been an S&MR engine. You can find his story in 'Neil the Boxy Little Engine'.
Den and Dart: Could be fun, but most likely as a cameo for diesels who live on the mainland (possibly at the NRM? I'm not sure).
Ryan: I have yet to decide where I fall on whether or not Ryan makes an appearance. He's a cool engine - and I like him, which is surprising for a CGI character - but at the same time, I must admit that it sort of felt like he was just a new version of Stanley to me. He may still appear as a cameo in a future story though!
Stanley: I already have a Stanley in the series, and it isn't the silver tank engine, though he would be one of the more interesting ones to have around for the weird one-sided rivalry Thomas has with him.
Paxton and Sidney: Another pair who may or may not cameo. I will say that there have been a number of Class 08s who make background appearances in 'The World Famous Engine', and you could headcanon them as one or both of the pair.
That's ten engines from past Season 7 that I debated plonking into my series. Thanks for the ask!
