Back during the Sage Mode training, Fukasaku tried to merge with Naruto but couldnot because the ninetails was still too rowdy back then and its chakra was a sinister one.
Now, however, Kurama is tamed and acknowledged by Naruto as a member of the Hidden Leaf. His chakra changed from an evil one to a chakra full of life energy- as shown by the wood stilts summoned by Yamato suddenly seems to have sprouted leaves.
So, coming back to my question, do you think that the frog sages can merge with Naruto? Will that somehow bring about a new Sage mode-kyuubi mode hybrid state?? Could the genjutsu of the sage duo now make Naruto into a complete warrior? If the sage-kyuubi hybrid mode make naruto arguably the strongest ninja in the series??
