Good bunch of info!! A possible far-fetched idea is that Stygians are like a lone wolf possibly Males as they wonder separately compared to regular Zinogre which raise young in herds. (Similar to elephant herds, females stick together males are lone). If Stygians are just a variant not a species of their own maybe they have a certain chromosome which determines their appearance. Or, scrap the gender based idea, that the determining chromosome makes them born as a Sygian means the rest of the pack kicks them out for being different or seen as weak offspring leaving them to fend for themselves.

As for Khezu only targeting live monsters to feed on is very interesting and using their electricity to detect live prey only sparked my interests. Pardon the pun :) Maybe they have a similar organ on their snout to the Ampullae of Lorenzini. It's the organ sharks use to detect the electrical fields from prey. When it plants its tail using electrical attacks it is "earthing" itself which we using in electricals to prevent an overflow of electricity causing damage. They may need their tails to earth themselves to stop from frying themselves?!? :'D As they get older they become more resilient to their own attacks.
