We had Santa in one of the first games I played. It went OK) I mean, I doubt we could bit him anyway (I have no idea what his stats were, but I guess he was some sort of celestial)... In this year Christmas episode, we were resolving some weird events in a city that ended up being caused by people in the city making pacts with a devil (devil himself didn't really parricipate in the whole chaos... Just set everything up for it).
