From the artist:  
“It is cool to make characters from other things into ponies, right?
 
Anywho this here is Gwendolyn, one of the main character fromt eh most fantastic of video games Odin Sphere. I chose to make her a pegacorn (I refuse to use the word alicorn because it’s inaccurate and pegacorn is funnier) because in the game she’s a valkyrie which automatically gives her wings but she also has a spear that she has to wield which can’t really be done with hooves so she got a horn. Also in the games she is a princess and kind of, sort of a goddess ish so I figured it was alright.”
