Let's do a #9 on all your major OCs.
I don’t really understand “major OC’s” so I’m just... gonna’ do a few ponies bc this is kind of a vague Q.
9. Name some of their major physical shortcomings.
Alton: small size & statureAlton is a small pony. Short & (what most ponies would consider) petite, but not slim or lanky. It’s not uncommon for other ponies to forget about him or simply not notice him around. Take it a step further, and you’d fine it’s hard for him to be taken with complete seriousness sometimes.
Other than that (which isn’t really even an issue), he’s in near-perfect health, physically.
Crystal: dexterityCrystal Lyne has got spunk in spades, and a lot of energy to deal with. Like a lot of foals, boundless energy just leads to clumsiness. Being a hippogriff, she has both claws and wings to coordinate, which can be tricky to teach herself to maneuver around sometimes.
This is more of an issue with age, though. Just something for her to grow into.
Step: deformity & dexteritySoft Step’s clearly out of the ordinary for an Earth Pony. Born with six legs, he gets the benefit of spreading out the pressure on his hooves one has from standing, walking, or running better than the average pony. The trade-off is having an overlapping gait, often tripping himself up when moving any faster than a trot.
Dusk: poor eyesightDusk Skies’ eyesight just... sucks. Especially for a pegasus, even. It’s kind of a big deal. He really should be wearing glasses, but he’s a stubborn fella. I can’t even really fluff this one up, that’s all there is to it.
