I am in love with how detailed your theory is. It makes my little nb heart scream with joy. It (and your blog) are awesome. I was wondering if you had any head canons about trans girl Marco that aren't proof of the theory? If that makes sense. Sorry if it doesn't.
No I get it and let me tell you…. hoo boy, I’ve been physically restraining myself from making up too many head-canons about trans Marco so that they don’t get caught up with the actual theory.
First off, I have another theory that ties into the Trans Marco one that I don’t talk as much about, and that’s that Star is ultimately going to reject her title as Princess & The Royal Mewni Family, and choosing to instead live on Earth. This is mostly based off a number of parallels to Trans Marco, the overall theme of not letting destiny define you established by Freeze Day. as well as the biggest instance of foreshadowing being the end credits to the show. (“I’m really thinking I could call this place home!”)
BELOW THE LINE IS PURE HEADCANON
I believe that Marco’s parents would be 100% supportive, that part’s obvious. But also believe that Star’s parents would also initially seem supportive of Marco.
However, they’d only be conditionally supportive. They’d be totally on bird with the whole “2 Queens” thing uuuuntill Star says she doesn’t want anything to do with that.
Then the facade drops.
