these are more reason i think necron is the most powerful.

FF1: they defeat chaos and restore peace and tons of crazy timeloop stuff happens.
FF2: they defeat th emporor.
FF3: ive not played it.
FF4: they beat zeromus and everythings happy.
FF5: pretty much the same.
FF6,7 and 8: as usual although the enemy makes a lot fo bad things happen they end up winning.
FF9: they beat kuja. but unlike any other FF villain that i know of necron does not lose and it was his choice to let the people continue living. its true that kuja destroyed entire worlds and nearly all of existence but necron never failed in his task. zidane and his group just delayed his task.

in FF5 it says that neo X-death has the power to do exactly the same thing and erase everything but the difference between them is that neo XD loses and necron doesnt. im not saying that necrons the most powerful no amatter what and ill never change my mind but from my point of view it makes a very good point. what do the rest of you think?
