Hey! I found your invader Zim AU very interesting, I would like to know if in your AU, Miyuki has any relationship with Dib and Gaz? And if somehow she had something more with Professor Membrane.
And sorry for my bad English, I'm basically writing for google translator
(It's nothing! I have a little bad English too, so I also use translator's help and can have some troubles in building sentences and it's very hard for me to write a whole texts. x) )
Yes, in this AU, Miyuki has some interactions with Membrane's children. When she saw them for the first time, her thoughts were: "I thought his parents were a little bit taller." (Based on one of the comic quarterly showing Membrane's parents and his dad were very similar to Gaz' appearance. I think Miyuki met them in the past once or twice in one of interactions with their son.)
Dib and Gaz, on the other hand, were confused by some alien lady knowing their dad... and their dad looking just like he had met her without any pretending that he's not. "What the hell is going on?" they asked themselves, especially Dib feeling himself betrayed and having a lot of questions to Membrane.
There's also a moment with one headcanon where young Membrane without his goggles and lab coat's collar would look similar to Dib in his most early concept-art (especially with his children being born in not natural way and Dib being some kind of clone or something like that) that makes Miyuki call DIb "Lil'brane".
Their relationship will be better in a future, but how - I'm not decided yet, sorry. For some reasons I've been thinking more on past interactions.
Before I answer the other part of question, I would want to say that there's the other part of this AU that shows Miyuki and Membrane's interactions in their past. Mostly it happening in some science-based college or institute (to place them in one building for meeting and starting competition without someone being higher then other in society) showing one joke made by my friend: Miyuki's disguise (fully realistic human hologram) seems like an alien appearance to the other people and gives birth to aliens-exists jokes and pays a lot of attention, while Spork (who is also lived the accident and followed Miyuki), like Zim, has only lenses and wig but seems to the others like a normal person and pays no attention to his look at all. And when Membrane discovers that Miyuki and Spork are actually aliens, he's not going to tell the others about it - he almost had known as human of "real science" and not going to risk his reputation and becoming wrong by telling someone about paranormal creatures that became real.
Talking about something more between Membrane and Miyuki - well, it's complicated. Representing my AUs with some two characters having close relationships to the others, I actually have two ways - friendship and romance. It's because I know there can be people who don't like when these characters having close relationships becoming love interests necessarily; and sometimes even I prefer way of friendship more than romantic; sometimes I follow two ways in one time, thinking how A and B are cute besties and drawing shippery doodles with them (even here, эхе, but I ship them anyway, tbh). You can choose the way you like more: Membrane and Miyuki as bffs (maybe somewhat that has name as brotp) or as two that overcame their enmity hills and united to role of lovely couple of top-scientists.
