Semi-Munchkined NPCs

[Tim Proctor]

I am creating some recurring NPCs that are sometimes on the side of the group and sometimes on the opposite of the group. So anyways here is the first one. I'm building them with the same rules that he characters have with their creation and the same amounts of money.

This guy is a psychotic assassin who is just crazy and ends up working with the group once before they find out that he's a psychopath and kills people for fun. ANY suggestions?

What is the question?

[nijineko]

ioun stone seems out of place on a ninja, but i guess he is not the sneaky type, per se.

i guess the questions is rather than any suggestions, is there a particular area that you are wanting suggestions in? i mean, the character is what it is? asking for suggestions seems like saying that you know something is wrong with these characters as presented. what are your thoughts?
