Here's Mia's orginal character design and description! Really, I thought about using this as her character profile image, but I figure that it'll be best if I just draw up an updated version of her for that.

Full Name: Miriam Othel Maenith

Age: 235 Years Old

Species: Doppelganger (a rare species of shape-shifter).

Personality: A curious, intelligent type, Mia is always exploring the world and finding things that interesting to her. As a doppelganger, she enjoys wandering around in public places, observing mortals as they go about their daily lives. She's usually in disguise, taking on the form of other mortals that interest her. Like the rest of her species, she also tends to be a bit mischievous at times.

Abilities: She is a shape-shifter, and has the ability to transform her body into any shape or size. At the same time, she's not exactly an elastic girl, as her primary form is solid, and thus isn't weak against extreme heat or cold. Her body is durable, yet malleable, and life span of her species is so long that, compared to the oldest of them, she might as be a young adult.

Her species is one of imitation, capable of taking on the form and sounds of the things around her. She can't copy abilities, though, and like many of her species, Mia is a mute, only able to imitate the voices/sound effects of everything around her.

History: Not much is known about Mia, and really, that's the way that she wants it...
