I would go with a trickster/chaos role. Loki if bad, Gwydion if good (he was a Welsh hero & trickster). I did a role like this in American Gods, and it is my favorite role ever. It was secret there so no one saw it coming

It was also an Indy recruiter, but that ight be overpowered in a speed setting.
If targeted, it fails, and the targeter is insanified (but is told only that s/he is insanified, not by whom). It can be tweaked to be bad or good. If civ, for every targeting, he gets another vote to use in the next day cycle. If bad he gets a vote removal for each time he is targeted, but it is cumulative. So he could conceivably remove a whole lynch.
When the game comes around, this will be a secret role & will be different, but this is the kind of role I like
