Actually, the MP version of the AI code is just a much older version of the SP code. They are fairly different from each other.
Anyway, the difference between the reborn and the wookee NPC is that the reborn was set up as a jedi character. There's a special situation where the force powers based reborn only have melee, but use their force powers as their main weapon. Sorry I can't be more specific, it's been a while since I've dealt with that code.
