Thinking about them again....
Headcanons for my Jamboree AU (I need a real name for this AU so bad):
Bonnie and Freddy were the originals, the first two designed by Henry and William so they are the favs, even if they no longer become the fan favs as the Theatre expands
The main 4 (Fred, Bonnie, Chica, Foxy) were originally their own band pre-expansion
Chica has a very ditzy but fun loving personality. Shes talkative, compassionate, and brightens any day. She can be a bit of a mother-hen to the kids, but her band mates treasure her like a younger sister.
Pre-expansion, Fred sings and announces the Theatre, Bonnie plays Guitar, Chica does duet and background vocals, and Foxy played the Piano/Keys
Post-Expansion, Foxy is booted from the main 4, instead becoming the main 3 as Foxy gets his own act on his own stage.
In the "Theatre Lore", Foxy has a twin sibling (Mangle) called "Maggy". Maggy is the mechanic/medic for the Theatre and all their DVD adventures. They have a more hands on experience for the kids with arts and crafts and even small displays on how animatronics run.
Later in the lore, the twins introduce their younger sister, a taller wolf animatronic called "Roxanne" who goes by Roxie. She has some inspo from Chicago and cabaret type pieces, kind of Jessica Rabbit-y in that her show is just a slower and very smooth sounding performance where she sings and her brother plays the keys. On adventures during the television programs, she may work with her sibling to help with makeup, paint jobs, or any other mishaps the gang may have. She also has an Easter egg for the adults in the audience thats part of her show thats basically just her love of cars parodying the scene from "My Cousin Vinny".
Montgomery Gator is part of the "Sunny Southern Sort", his own sort of group with their own rustic Southern theme. The group includes Monty on the drums, Bubba on the Harmonica, and Porkpatch on the Fiddle. (I need to add their redesigns bad)
Marionette comes post expansion but before the Sunny Southerns. They are a portrait bot running the prize corner. They have a comedy routine and skit they do that is interactive with the employee who works the prize corner. They have 4 separate pre-prepared routines so that its unlikely customers will hear the same routine twice in a stay and ruin their immersion.
Sun and Moon are two separate portrait bots that sit right beside the stage against the wall. They joke back and forth similar to Statler and Waldorf from the Muppets and are meant to entertain the audience pre and post show as they settle and leave their seats. They also act as distractions between shows for seamless entertainment. They may also sing along during different numbers and interact with the other animatronics. They are added pre-Music Maestro but post Sunny Southerns.
Music Maestro acts as the Theatre's conductor and works in tandem with Freddy to keep everything and everyone running smoothly. He does not speak and only communicates through musical notes, but his children, Sun and Moon are always sure to translate for the audience if the performers dont. In his first drafts, it was going to be that his hands would open and close the curtains, but that was scrapped to allow for easy expansion.
Paulie and Bon-Bon (aka funtime freddy [name is still a WIP]) are one of the newest additions as a comedy routine and duet using vantriloquism. Of course, their voices are completely different and they have different voice boxes, but the audience doesnt need to know that! Dont spoil their fun! Paulie is Freddy's cousin and a friend of Maggy.
Okay thats it. I may add more later but for the time being I love them...
