Yeah, changeling. They got some feats where their subtype actually changes to what they imitate.
If you want James Bond, however, James Bond had the following:
1. One truly amazing Artificer outfitting him with wickedly munchkin-approved items. (Q)
2. Off the chart skill bonuses. Specifically bluff, diplomacy, spot, listen, search, move silently, and hide. In later years he picked up amazing levels of Jump and tumbling. Seriously, he was always an action star, but Quantum of Solace took it to an absurd level.
3. He's a monk. He takes people down with one blow. That's stunning fist if I ever heard it. He never wears body armor. However, he's only got two levels for the evasion
4. Because he's actually an Erudite With Ascetic Psion and Tarshalona when it comes to the actual combat skills. He's picked up a few buff powers/spells and basically uses charm person like it was going out of style. All his weapons are actually the few energy X psionic powers that he picked up over the years, but he managed to get a variant of primitive caster so he can add foci (guns and missile launchers and what not) to increase the ML and thus the damage of his weapons. You could make an effective james bond around 9th level, IMHO.
