Firstly we have the twins Peanut (male) and Jelly (female), and then little Funfetti (female).

First is Elusive Storm (male) and then there's Snow Thunder (female).

5: Rainbow Dash x Soarin

Firstly is Iridescence (female) and then there's Pastel Flash (male).

Full body Trick:

Then we have some other characters I made that are shipped with some characters here:

Seastar and Starfish, who are female twins.

Sweetcake, who is a male (and I didn't color him, whoops)

Mirage, who is female and a draconequus.

If you'd like to know more about the characters here and give your own headcanons on them, I will be making a book for all these!
