Thus Blue cross slitted eyes with red highlights, and sh**tloads of white chakra whisping around him until he attacks (i.e makes him look like an angel... What? That would be soo cool. You have evil dark Sasuke, and good light Naruto, epic on so many levels)
Only problem is 1) he'd need full control of Kyuubi (though with the manga going the way it is, it seems likely)
and 2) not only pumping his chakra into the sage mode but using an amount of his own to make equal parts S/K/N would take so much chakra i think it would use all of his huge reserves at once.
So, anyone want to draw it? Have Naruto with blue cross slitted eyes and red markings, plus whips of white flowing around him and him seeming to glow. Well, that was what i imagined anyway
