I have yet to see a franchise that Funko has turned down. They might as well get in on Sonichu. Had Chris discovered Funko Pops a few years ago, before discovering that his fandase will give him money for doing nothing, he probably would have created a line himself that he'd be hocking on eBay.
Funkopop is the most blatant monetization of autism possible. The cookie-cutter business model where they just plug in whichever obsessive fan base. The appeal to that autistic collector, completionist instinct. The dead-eyed, vacant expression the figures all have. The way they're all the same and only distinguishable by stuff like clothes and hairstyle. It's like the whole company was made to appeal to Chris.
