so i'm finally writing a bit down for how i would interpret the sb gang as humans - well, humanoids (more so than some of them already are) and i thought i'd make a little bit of an "intro" post to springboard off of with ideas (plus, if it makes anyone else want to request things, they're welcome to!)
First of all, I am enamoured with the concept of them still being robots, just humanoid ones. I'm thinking something vaguely Detroit: Become Human android-esque - they're extremely lifelike and still sentient, but they're just designed to look human instead of like animals... mostly.
The Glamrocks still have their animalistic theming - from some animal features to still animal-themed merch, the inspiration is there. It makes sense - they're designed to entertain kids, and who didn't wish they were part wolf or part cat as a kid, at least a little bit? (From a worldbuilding standpoint, not every android in existence would have animal features, they just get it because they're entertainers).
The animatronics - androids, robots, whatever you wanna call them - are in general still taller and larger than life than humans, except in the case of ones like the Daycare Attendant and especially DJ Music Man, maybe not quite as tall as their canon counterparts. It's easy to pick them out in a crowd even without the bright coloured designs, just because they stand head and shoulders over the average human.
While I do have some specific headcanons for how they look as humanoids, I'll try and keep it vague so people can come up with their own ideas (or, if I write fic for this maybe I'll just describe them there).
The AU runs pretty much the same as canon, or my interpretation of it, the appearances are pretty much the only difference! Maybe people treat them a little bit closer to human, since they look the part, but that's about it!
