Lucasarts.com recently placed up their first profile for the KOTOR 2 characters that'll be able to join your party. The first character profile up being that of Mira.

Mira is a bounty hunter scout that scours the Republic and the Outer Rim in search of prey and cashes targets in for credits. While driven by a mercenary need for cash, Mira shys away from contract killing or performing contracts for the Exchange - in the past, she has killed only in self-defense, and even then, she has done so reluctantly.

Aside with the profile there is also a new screenshot of her that can be viewed. Check out the full profile at LucasArts.
Thanks to Tyrell for the write-up!
