This is the first pic in a little series I made to sum up the fighting styles I associate with each of the main species in MLP (full list: fav.me/dcab8b3)  
For anyone whose watched my gallery for any length of time this is probably the most obvious, pony’s get ninjutsu and everything associated with that. I decided to use a moment from the episode School Daze pt. 1 for this pic both because I really like that moment (I find it cute) and it gives me a way to explain the Changelings as well (for those not aware the blue haired one is actually a shape shifter) since I don’t really associate any style with them specifically but I do think they could use the style of whatever they turn into. Also, Ocellus is my favorite of the cast of students and I wanted to include her.  
I don’t own these characters just the pic
