Damn it, Mech. More ponies?
Any way, this is a depiction of a scene from the fan fic Fallout: Equestria-Project Horizons.
Main protagonist BlackJack squares off against the foul mouthed, monsterous cyborg of a pony that is Deus. Very intense fight it was.
Designing Deus was a challenge, and I'm still not completely satisfied with what I've made of him, but it seems well enough.
Fully reccomend checking out FO:E and FO:E-PH to anyone, pony fan or not.
