Re: What secret purpose did the Uchiha clan originally serve?
to control the kyuubi, it was stated by itachi in his last fight..
Itachi"from the moment u unlock the mks ur eyes begin to lose their light"
sasuke" so that's the price u pay for gaining control of the kyuubi"
itachi"it seems u took my advice nd read went down blah blah blah.."
yeah thats it.
