Baldur's Gate II character. Yoshimo is the only really acceptable thief in the game (Imoen is all you'll ever need anyway though). And even so he outlives his usefulness pretty quickly.
What makes
Yoshimo worth having is that he's a
bounty hunter, and their special
traps can be pretty useful.
Fortunately, when it's time for him to (try to) do you in he doesn't use them.

Spoiler below:
Yoshimo plans to betray you - so fair warning. Conviently, Yoshimo betrays you exactly when Imoen returns, nicely replacing him and allowing you to have a good/adequate thief all the way through the game.
