Junior Flight Lieutenant from the mechanized aviation section of the shadowbolts.

Nightmareverse. Taken, the art and much of idea of the character, from Equestria at war. Rest is naturally MLP.

Nightmareverse is an alternate MLP setting where Nightmare Moon has ruled for over a thousand years. A vast, multi-species Lunar Empire thrives under eternal night, blending early industrial technology with magic. Society is stable but controlled, loyalty is expected, and power flows from a divine Empress who has seen everything before. Not grimdark but darker.
