Excellent!
I didn't make a preview image.
I can provide examples of the shapes that people have drawn:
Transmasc Pikachu with stitched tail: https://www.furaffinity.net/view/39071465/
Intersex Pikachu (not fully heart or square): https://www.deviantart.com/twinkel13/art/Intersex-Pikachu-561094460
Flame Tail Nonbinary Pikachu: https://www.deviantart.com/lovelatias/art/Non-binary-pikachu-706846661
Double Triangle Tail Nonbinary Pikachu: https://www.deviantart.com/attemptinggood/art/Gender-neutral-Pikachu-903517742
Also, things can get even more interesting to think about when we throw intersex into the equation.
Where this gets even more interesting is: Some transmasc Pikachu art features the two sections of the "heart" tail stitched together. As for how the transfem Pikachu counterpart to that would work, my guess is that it would involve reshaping of the tail.
As for Pikachu tails on Pikachus that are not male or female look, there are several ways people draw those: Some are drawn in a way that differs majorly from heart or square tails, one example being a mostly-triangular end, somewhat modeled after flames. One intersex Pikachu artwork I saw is one where half the tail is heart, the other half square. A theoretical ADDITIONAL way to draw a non-masc non-fem Pikachu tail is for the tips of a heart Pikachu tail's hearts to be a shape that is not round, so something like a triangle, square (so a notched square tail), or something else, or to have the entire tail end be an arbitrary shape. Or you could have the whole tail end in a circle. There are MANY ways to draw a Pikachu tail that is not masc or fem.
And don't even get me started on what some sectors of the furry community believe intersex is. As someone who has been a furry for many years, I've definitely found a LOT of inaccurate stuff in the community regarding intersex matters. Also, DeviantArt and etc. al. are no better. Now, the furry community in particular is where these inaccuracies get fleshed out to significant extremes, including even custom symbols largely belonging to a term I cannot utter here. The community ESPECIALLY has inaccuracy issues when it comes to the topic of reproduction, as does DeviantArt. OH, and that isn't the only relevant thing they get wrong. They get a LOT more wrong. Not to mention that they also get stuff wrong about trans and nonbinary people too. God, certain parts of the internet REALLY don't know how things work. Like, they completely miss the mark, and it goes awry fast in a way that completely misrepresents what being intersex is, and same for their treatment of trans and nonbinary people. People just buy into stereotypes, and of course, that doesn't end well, and it only clouds things up as to how things actually work. Better and more accurate representation is needed in creative works, and desperately so.
I would say that a fursona species that would have heavy vibes with trans people would be species capable of shapeshifting. My fursona is effectively an anthropomorphic version of the feline shape-shifting Pokemon known as Mew, but specifically the shiny form.
I'm not going to remove this post.
Interestingly enough, I'm also a salmacian/aphrodisian (I want a PPV with no orchi), and in Summer 2022 into part of Fall 2022, I was a member of r/Salmacian's Discord server, a place in which there was significant toxicity, and the server broke with EVERY other LGBTQ+ server I've been in, and allowed people to refer to themselves with terms that would get one automatically banned from most LGBTQ+ servers. There were also other questionable managerial decisions made there.
Thanks!
I had to deal with a binary-only form at my dermatologist, and I went Costco shopping and I'm drained, especially after the dentist. I have an endocrinology lab tomorrow. Otherwise, I'm fine.
I'm actually intersex (I have multiple intersex conditions), but in a manner closer to AMAB than AFAB. Now, admittedly, my first sona's original incarnation at its original inception was essentially that (what you mentioned) to some degree. My transition options in the end ultimately are ones involving a PPV with no orchi.
