the evil minions of the evil Sorceress, armed with weapons designed by Robotnik

these are shadow beings, made of the negative parts of the mortal soul, they do not come in huge numbers, but they are smart, cunning and can hold their own against most mortal beings, and have an inbuilt desire to fight even til the end of their existance

I gave them a bit more of a mobian twist, cause this ranger story does cross slightly with the sonic universe (well so far its only with Robotnik and some of his bots, but who knows who might appear)
