One of the characters in my campaign has Zuckuss as a contact/small source of Obligation. I'm keen on having Zuckuss betray the PC in order to collect on his debt (and to also move the story forward), but that means putting Big Z in a situation where he might get ganked by the PCs. I'm okay with this (I'm running an Alt Universe campaign so canon characters biting it aren't a big deal), but it got me to wondering if he's a Rival (I was thinking Adversary 2) or a Nemesis. Zuckuss in general isn't strong enough to be an end-of-campaign bad guy (which is my metric for a Nemesis) but I don't want him to get chewed up and spit out without a challenge by the PCs if things turn sour.
Thoughts?
