I don’t think it’s possible for me to impregnate you, Lyra, but that won’t stop me from trying to do so every day for the rest of my life until I succeed.

I just replied to the last one after reading them all to get all the context. That’s all. I was too lazy to scroll back down and get it.

@Prism King  
It’s… the one that you replied to, though, can’t you reply to the older one?

@Background Pony #2F29  
Relevant to the comments about what it could result in, and that’s what I was raplying to, not that. Just because I’m late, it doesn’t mean I must be replying to the most recent.

@Prism King  
Yeah but… not relevant to their comments about ancient furries, is it?

@Background Pony #2F29  
I was explaining another way of looking at things: no hybrids, only either full pony ro full human. I explained where I got it from.

@Prism King  
I… what does that have to do with… anything they said?

Have you ever heard of a game called “Class of Heroes”? Likely not, as it didn’t sell that well stateside or in Europe, so 2 and 3 were Japan exclusives, iirc. I get my interpretation of how human/pony interbreeding works from there:
 
Here we have the “Ten Races”: Humans, Elves, Dwarves (who actually have doglike features), Sprites (Like small foot tall fairies), Halfings (resemble human children, even as adults), Erdgeists (Earth spirits who possess animate dolls to interact with the other nine races), Felpiers (basically anime cat-girls and cat-boys), Drakes (human-esque beings with some dragon features and are always large in stature), Celestians (A human-esque race descended from Angels), and Diablons (a human-esque race descended from demons). The game is about a school for adventurers. The Class President, Max, is a Celestian, and the “Boss”, Tax, a delinquent, is a Diablos (singular form of Diablons). Turns out, they’re blood brothers, with their parents being one Celstian and one Diablos. In CoH, it’s a 50/50 chance for the child to be pure-blooded of either the mother or the father’s race.
 
In my works, I treat human-pony unions the same way: 50/50 chance of a foal or a baby. I liked the idea and ran with it. There’s another way of seeing things.

@Stotter  
Furry existed since ancient times long before the word “fandom” even exists.

@Background Pony #FD83  
Technically, there are some ancient depictions of horse headed humanoids you can retroactively describe as anthro.  
If you’re more general, the Egyptian gods are mostly depicted as anthro, but since those depictions weren’t meant to be literal, would qualify more as fursonas for the gods.

@Background Pony #92A0  
It’s fine, I knew what you meant anyway.

@Background Pony #FD83  
Oh my, I incidentally include it as such.

@Background Pony #92A0  
Well, while people have been anthropomorphizing things in stories for just about as long as people have been telling stories, I wouldn’t exactly call anthropomorphized MLP Ponies a “species of ancient myth”.

@Background Pony #FD83  
Say, it’s a never seen before cute hybrid idea and so original, too bad it is still not as popular as the three species of the ancient myth you mentioned.

@Background Pony #92A0  
I think it’d be more likely to turn out like Lucky Suzie than as a centaur, a satyr, or an anthro.

Lyra: Make a centaur! Activate Centaur Breeding Program!

I don’t think that’s biologically possible, Lyra. Oh well, won’t stop me from trying.

@abackgroundpony  
But… I don’t want my dear Lyra to do that! I want a human son and a pony daughter! Why can’t you accept our desire to have a mixed family? Why must you disapprove of our shared desire? It’s hers, too!

Needs a follow up with a heavily pregnant Lyra carrying what’s revealed via an xray inlay to be a pair of perfectly Human twin babies in her Equestrian womb <3

If it were any other pony, maybe not. But this is Lyra Heartstrings. According to official character bio cards accompanying some of her official merchandise, she’s incredibly interested in the stories Twilight has about her adventures on the “other side of the mirror” (aka: the human world). Since Twilight attended a human high school during that time, maybe she learned about human biology in a class. Or maybe she studies it from books on that side to help her better understand her new form. Either way, she’d have likely run across human reproduction. Lyra might’ve asked for the details on it, and if she could manage to get the info from Twilight, she’d have all she needed to be able to transmute a pony egg cell into a human one. And as for making human sperm become pony sperm? She’s already a pony! That knowledge is in books in her world already!
 
Now, as for size? How can you prove it’s too small? What if transmutation is no respecter of size? We already saw it doesn’t respect mass (there’s no way a mouse has the same amount of mass or matter as a horse (which, as we saw, is larger than a pony)), so why should size matter in this case, either? We’ve never seen any true limitations on transformation. (And if there somehow was, she could ask Discord for help. He takes your precious logic and removes it entirely).
 
Still, cut it out with the logic crap. I’ve said it before, and I’ll say it again, seeing as you guys just don’t get it.:
 
 

 
Magical talking pastel-colored ponies already are illogical! Trying to apply logic to the illogical just ruins everything! Take your real world logic somewhere else, like, say, THE REAL WORLD?

@SnoopyStallion  
Irl probably more than some would like to believe  
i don’t care i want many horse babies

@Tinandel  
Gosh just imagine all the humanhorses that would excist at this point when humans could actually impregnate horses or other animals xD

@SnoopyStallion  
Not with THAT attitude!

Silly lyra. Humans and pones cant have babies.

@Prism King  
Do ponies know about that stuff? Their scientific knowledge is somewhat inconsistent. If they do, are you sure such a spell can work on something so small?
