Practical Joker
Quirk, mental, -1 point.
Use the rules for Trickster, but replace the need to fool dangerous foes with a propensity to play jokes on friendly acquaintances whom you believe will “appreciate” the humor and laugh with you. Not all of them will, of course – even Allies might react at -1 or worse after such an episode! When you need to resist this urge, your self-control roll is 15.
This amounts to Trickster (15) (Accessibility, Only on harmless people, -80%) [-1].
