Alright first off these will never get finished. These are my original OC's I created over 6 years age.

The close horse face is Mighella revealing her eyes- long backstory she but she didn't show her eyes only to her victims before she killed them and yes she is to this very day the worse of all my character as being evil.

The top two horses as the same horse, Black Heart had split personality inside of him which he called Insanity, pretty much like jackel and hyde the two would fight with each other, one intent on killing the other intent on protecting.

The horse with armour and wings is Mighella in her final form. She was a bender of elements and came to claim all elements for herself, her final form was morphing her bones into metal and creating armour to sheild herself, although I was never able to show this in any rp. And yes even those wings are metal that she could indeed use for flight using all the other main elements.
