Well let me tell you that this FNAF lore is pretty cool, but to end my annoying questions, it would be interesting if you ever made a drawing of Chica and Freddy showing their gentiles, explaining their species at a structural level. But if it were up to me, you could have expanded a little more on the matter, since it would be interesting to know how Freddy and Chica would have a child knowing the context of their species.
With Roxy, I have a doubt about your only sketch, from what I understand, she is trans according to your boyfriend, right? So I'm curious to know if she retains a masculine structure with a feminine aesthetic or if she is 100% transitioned or if she has a different genital structure than being a werewolf literally (sorry, my ignorance of trans issues is a rather extensive topic than what I thought).
I DID make a mild deconstruction on how Ursin-ul anatomy differs from that of an Earth Bear; as well as how Meravians are different than Landavians though I lost those..... but the reproductive organs? Uhhh- SMOKE BOMB DISTRACTION!!!! 💣💨💥💨💥💨💥💨💥💨💥💨💥💨
Children are non-canon to the au, and how Freddy and Chica end up with a child is.... actually kind of fucked up?? 😭😭Because Nathaniel (I think that's the name I gave) was synthesized using both Freddy and Chica's DNA instead of the usual coitus and it... it definitely adds some drama to how the family handles that fact
Compared to his half-sibling Ace, who WAS conceived via Roxy getting Chica pregnant (and just really makes Freddy's race on a whole different level of "WHAT THE FUCK ARE YOU DOINGGGGG")
I distinctly remember when me and Nexus were talking about it, that Nathaniel ended up feeling alienated from both parents, and Chica not really feeling as strong of a maternal instinct towards Nathan because Chica didn't get an egg inside of her fertilized and laid to be cared for (basically the whole mother-child maternal bonding experience), Freddy just.... basically came back with a synthesized egg that carried both his and Chica's dna
And that fact made it so much worse that it actually messes with him and the validity of his existence in the first place
It's uh... I'm just now realizing how fucking sad that is, oh god now I feel really bad nooooooo Nathaniel....... Why'd it have to be this way my boy...... 😔😔😔
As for the other question: yes that is correct, she is indeed mtf trans and I think she's taking hrt? Because she has feminine features like her boobs-- but she hasn't had surgery/chose to keep her cock, I can't remember the exact reasoning god it's been a while since I've worked on this AU
