I'm currently playing a Ninja/Swashbuckler Kitsune with the Fast Shifter race trait and Realistic Likeness feat.
As a move action, turn into anyone you have seen as with a +10 bonus on Disguise.
Str 10(12), Dex 18(16, 20 with +2 belt) Con 14 Int 10 Wis 10 Cha 16(14)
At level 4 I have Ninja 1/Swashbuckler 4 (planning on Swashbuckler 5/Ninja 7 for PFS), at +10 doing d8+9 (18-20x2). Weapon Focus(katana), Slashing Grace, Combat Reflexes, Realistic Likeness feats.
I have a +21 to impersonate someone I have seen with disguise, so a base 31 just taking 10.
I have Sleeves of Many Garments, to make sure my clothes are exactly what I need, (200g), and a +19 acrobatics to tumble around an enemy to get the flank for my sneak attack(1.5x800g for 1200g added to the Belt of Dex to get the benefit of Belt of Tumbling as well). Mithril Chain shirt and Darkwood Buckler gets him to AC 21, start adding AC from there pretty easy for fairly cheap.
You can later get Elven Chain for 5150 g, +6 armor with +6 max dex if you need it that is always light armor.
He's charismatic, has plenty of skills to have some social and knowledges, and makes a decent face character as well as doing decent damage.
