I’m not including any details as those can be found in the RIFTS book and I don’t want to tread on anyone’s rights or anything here, or to remove the need for the actual books.
Crazies in a FATE version of RIFTS would have the following traits:
Stunt: Superhuman Physique
Crazies have enhanced bodies, giving them superhuman Strength and Endurance. In any test involving strength or endurance they get a +1 bonus.
Stunt: Superhuman Speed
Crazies have augmented reflexes and agility. In any test involving speed or agility they get a +1 bonus.
Stunt: Enhanced Senses
Crazies have enhanced, twitchy, senses and gain a +2 bonus when rolling on those senses.
Crazies remove their least bad consequence each scene, along with their physical stress.
Crazies can choose three minor psionic powers from Sensitive or physical lists (excluding Astral Projection, Ectoplasm, Object Read and Telekinesis). Technically each spell operates as a Stunt, but this is considered a single Stunt. Additional powers later on are considered individual stunts when purchased.
Crazies start with a negative aspect relating to an insanity and whenever they buy a new Stunt or increase their Refresh they must take another (maximum 8 insanities from this cause).
