Ik this isn't TSAMS or TALES, but, what are your puppet headcanons or FC ones? Maybe Frankie from MAaGRs if you have 'em?
I'm on a roll, putting FC and Frankie let's goooo!
FC
(EAPS spoilers for today) Spent that 3 weeks in the dying dimension jumping around and sort of talking to Andrew. OK, Andrew tried to talk things out, FC made it clear that honestly, no amount of talking could fix how things happened between them. They ultimately settled on treating each other like cousins who will bully each other but play together at family gatherings because there's no one else.
Similarly to Earth's experience with negative star power, FC permanently has pain ever since the Stitchwraith sent all that NSP directly through him. Putting the core in him helped, but he is near-constantly (unconsciously) using some amount of star power to stop the pain.
FC was mentally around 5 at creation, and after his incident with NSP, he quickly progressed to being mentally 10. When Monty made his new body, he ensured FC's AI would progress gradually, year by year, like a human's. This can be adjusted if he ever decided he wanted to become a teenager overnight, or just grow up, but given he basically skipped the first ten years of being a kid, he's alright taking it slow.
School didn't really work out for him. He was dealing with trauma, lack of structure, lack of parental figures, and had very different needs than human children regardless. He would lash out and harm other students, and refuse to listen to the teachers. After repeated issues, he was expelled from two different schools before Foxy began to homeschool.
He really did look up to Stitchwraith and want his approval. Sometimes he still feels that urge when talking to Andrew.
BUT, now that Andrew's visually a child, and is acting a lot more like one too... Well, it's a lot easier to snap back and stand up for himself to a bully his age rather than his mysterious creator(s).
FC hasn't had a lot of time to process how he feels about Jake. The first one. Jake, who created him. Who was, sometimes, actually kind to him. Who more often than not, wasn't. Who almost, but didn't quite, stop the torture he was going through. Who used his last bit of energy to save his life.
He's determined to be a good actor, because he understands that his mom being happy again, and his dad returning, depends on them all pretending... But he feels a horrible guilt each time he successfully convinces Puppet he hates her. It's just so easy.
FC really, really misses sleeping on the couch with his mom.
FC actually really likes the Captain. He thinks he's cool. Not as cool as his father, the great Foxy, of course. But pretty cool.
Frankie
Gets advice from Ennard over the phone on how to deal with the chaos that happens in that household. Also gets prank advice in return for doritos.
Designed his own new body (which is canon), but spent a really long time doing so. His first few ideas were combinations of Roxanne and Glamrock Freddy, trying to go back and forth wondering how much of each parent he wanted to incorporate. Eventually Michael looked at his designs and remarked that he's just designing a mishmash - he wasn't designing himself. Michael had used parts from Roxanne and Freddy, and they'd accepted each other as family, but Frankie doesn't need to be a mix of them - he should just be whatever feels right. After that, it only took a few more designs... a couple... dozen.... Building a body is a big deal okay!!
(based on the MAGF livestream today) is really enjoying school, especially science and tech classes! His knowledge of technology, due to living with Michael and for a while almost purely being surrounded by robotics and coding, is way beyond what the class teaches. But that just means he's made a lot of friends by helping out struggling classmates!
He called Michael his dad without thinking about it while talking to friends at school, and just kept that up when referring to him. Then he did it in front of Michael one day, and immediately stopped in his tracks and apologized. Michael, while surprised, just reassured Frankie that it was okay.
Frankie's magic practice is going way too slow for his tastes. He is pretty interested in seeing what ways he can make magic and technology integrate, which Glamrock Freddy is not totally sure is a good idea.
Look what you've done, Michael. This bearwolf has anxiety.
It sucks when you're thinking about him and you soon realize that you should stop because you will never have a chance with him no matter how hard you try
