no she will become more powerful than him and guess what her apprentice becomes more powerful than her and that's how it goes until palpy the most powerful of them all.
and if his plan of turning anakin to the darkside wasn't mesed up by obi-wan than anakin would have become more powerful than palpatine.
Completely irrelevant. Anakin Skywalker was the most powerful individual ever born; he would have become more powerful than Palpatine with or without the tutelage of the Sith.
I think the entire point of the Rule of Two is that your apprentice is supposed to surpass you.
Not that it actually happened that way, but still. Bane jumped the shark past book one. He served his purpose in the first book. Why do we need a third one on him?
Because he's a decent character with a fanbase that wants to know what happens to him beyond 'he dies'. I mean what was the purpose of writing about what happened after ROTJ? To serve the fans who were curious. Same here.
Plus there are still moons who don't bow down to his awesome powa!!1! Examples must be set.
I will after the book has come out and she is more powerful
revan and malak weren't under the same rule of two as banes order.
and the entire nature of the banes rule of two is to make the sith stronger. like gideon said it may have not turned out that way but so far the way zannah's character has been written implies that she will become more powerful than Bane and the rule of two also implies that she will surpass Bane in power because that's the whole point
1.) You can't presume that something is going to happen and then treat it like established canon.
2.) There is no evidence to support the theory that each successive Sith Lord is more powerful than his or her master. Bane's Order was as much about ideology, knowledge, and planning as it was about brute force, if not moreso.
