You can't go wrong with a virus villain like Venjix in this situation! Or you could try someone like Ultron from Marvel comics. Those are pretty basic

Or you could do something odd, like a rouge Dark Network scientist who becomes a teacher at the ranger's school and makes his students create programs that would make the monsters of the week and a device that would bring out the Dark Network into the real world. Perhaps the rangers are even in this class and don't realize their homework is really to create machines of war that they end up fighting aginst by the end of the week. Maybe the scientist doesn't even know the rangers are in the class.

You could do alot of things with the villains and get downright crazy.
