EVERYPONY LINE UP

all of them!! together!! my height headcanons/personal designs. Most of them are pretty similar to the show and I might still mess with Pinkie's, I'm not super satisfied with her design. I've always imagined her as a huge party girl…literally. She's the 3rd tallest of the mane six (after Fluttershy and post-ascension Twilight) and MASSIVE. When she bounces around the ground shakes type of huge. I also thought the thing they did with the candy in her mane in the finale was cute so I used that.
I gave Fluttershy an inverted, slightly mutated version of a classic bat pony mark (Princess Luna has the same one). She's part bat pony on her father's side, she looks even more "batty" than her father and certainly more batty than her pegasus-passing brother. It's something she was picked on in school and still has a little bit of a complex about.

Rainbow Dash is tiny. I imagine that's why she's able to go so fast. She's like a cross between a falcon and a hummingbird. Her wife Gilda is slightly smaller still

Which: imagine Gilda's debut episode but with these sizes. It's really funny. I know griffons are usually big in lore but idk I like the idea of the MLP ones being kinda small, closer to bird of prey/housecat size than lion/horse size…this could all just be rationalization for tiny bird wives. SO BE IT.

On the opposite end…Twilight's wife Tempest is fuckin huge

But that's more in line with canon. Tempest is significantly bigger than the mane six in the movie.

Starlight and Trixie? Starlight is between Rainbow and Applejack, Trixie is between Pinkie and Fluttershy probably
