Passion finally has an official Nightmare Form look :D Armor design will come later, but here's the main look. The eyes, fangs and scales on the hooves is because in his/her Nightmare Form, it taps in to the latent power of his/her dragon form, but unlike the dragon form, he remains in control, instead of the dragon mind taking over. Keep in mind, in my OC canon fics, Nightmare form is exclusive to mares, so even if he's in his normal male form, when he goes Nightmare, he will become a mare in the process :)
