Lenitae

Clothed:

Lenitae appears to be a rather large unicorn, with royal blue fur, a cyan mane, and cyan eyes. With a height of six feet and three inches, including her horn, she is quite the imposing sight. Regardless of her size, she has a gentle and graceful step, almost like a royal.
The big mare wears a helmet one would usually find with biohazard workers, covering her head, her horn, and even her face, while allowing her mane to exit the helmet at her neck.
She also wears a leather jacket which covers her front and midsection, thus also covering her wings in order to fool people into thinking she was just a large unicorn. Of course this disguise doesn't stand up to an inspection. Given the jacket is worn open, it can easily be moved aside by spreading her wings, allowing for unhindered flight. The mare's rear is not covered, meaning that a lot is visible back there.
Over her flanks she wears a pair of saddlebags, hiding her cutiemark, or lack thereof.

Nude:

Lenitae is very clearly an alicorn, standing at six foot three inches tall. Her body seems to be in rather good shape, and while not the strongest, she seems to be able to pack a punch. Even with her size, she has a graceful step.
Her flanks are blank, which isn't unusual for an alicorn, but unusual for some to see.
