What we have here is Mutalation and I's "Psycho Rangers" of the mlp universe called the Shadow Guards. The shadow guards are led by a stallion named Malum who along with his crew of Five represent the elements of Darkness; six magical elements created to counter the elements of Harmony; This picture here is their leader; Malum, dressed in a stolen prototype Equestrian battle armor created by the royal ministry of defense after the Canterlot invasion by the changelings to protect and save soldiers lives. After being defeated by Twilight and her friends, Malum and his group stole these suits because they were designed to counter anything thrown at them, making the pony wearing the armor to be a "Super-Soldier."
The suit uses steel to counter Earth Pony attacks, it is held together by artificial leather undersuit to resist Pegasi wind attacks, and the pylons on the head, legs, and chest are to absorb unicorn magic attacks. You can tell which Shadow Guard is after which Harmony element due to the cutie mark emblem enveloped in flames on the chest and the stripes adorned all over the armor (Purple for Twilight, Cyan for Rainbow, etc)
well I did try to make this out of my imagination; a mash up of both the Psycho Rangers from Power Rangers in Space, and the ultra-robots from Samurai Jack. So sorry if it is not the best looking thing I ever made ' but hey I think it is cool :)
