My character's primary focus is as an assassin.
Combat wise, the current build I've got working up for her has her being sort of versatile, but leaning more towards ranged combat. Essentially, she's a sniper who can handle herself in melee combat, is fairly good at avoiding damage, but is pretty crap at actually taking a punch if she DOES get hit. From the way she's shaping up, her best position in battle is camping outside of the enemy's range and picking them off with her rifle.
Her main contributions to the team outside of battle would be stealth and tracking. She's good at getting to where she needs to be, and getting there unseen, and is quite capable of pursuing a target regardless of what kind of terrain the trail leads through.
She's also not terribly charismatic, though. Hey, with all the money that no doubt went into making a human replica droid with assassination protocols, they just didn't have anything leftover to give her a charming personality with.
As for those pics, wigglebiscuit... I think I like pic 1 more overall, but pic 2 has freckles. Hnnnnng freckles.
