[b]Mars[/b]

Regular Traits: 

Upgrade Slippery to Rank 2
Add Acrobatics (Rank 1)

Custom Traits: 

Upgraded Unorthodox (Rank 1) to Rank 2.

Unorthodox: A fair fight is noble, but being noble isn't always being smart. Some call it Unorthodox, others call it cheating, but Mars calls it ingenuity. This lifestyle builds a reputation that attracts the wrong kind of people... or the right kind, depending on your perspective.

(Allows Mars to better see opportunities to 'cheat' and grants a diplomatic bonus with Chaotic Neutral and Lawful Evil characters, maybe Chaotic Good depending on the character. Diplomatic penalty against Lawful Good characters.)

Added Trait:

 Opportunistic: Stab em in the back then kick em when they're down!
(Bonus to actions performed against unalert characters and wounded characters to a lesser extent)
