Seers and watchers are the most dangerous townies, I'm not gonna give town another one just to maybe strikeout a single vote.
This reminds me. I have played 12 games here by my count. (Not including the ones I ran.) Looking at all the ones I can find I realized that I've been seer/watcher alot. I have 5 non town/or shouldn't count per se because they were odd.
1 as a wolf
1 as a neutral
1 crazy idea as a universal backup
1 spy game which is weird
1 midwest mafia with no powers

So of the rest:
A power copier in wizard tower
A public seer in spongebob
A watcher in Harry potter and the doppelganger one
Then for evil villain, beware of bites, witch hunt, and this one I was a seer.
