Orochimaru's gonna be a ***** to kill now. Theory
This is 100% my theory, I've not bothered to read others opinions on the matter so no accusations of plagiarism please
If there was ever any doubt in him being the last villain, this should hopefully help clear stuff up.
This isn't an Orochimaru's top ten thread, it's my theory that recent developments in the story have led to Orochimaru becoming not necessarily unkillable, but pretty dam close. Please no rage, I'm not some Orochimaru fanboy overhyping a new power up, I'm just stating what I think. In fact, I've always put him down as one of the weaker characters of Naruto, but after several significant developments he has definitely become something to fear to the characters in Naruto.
(Sorry i don't know how to put manga extracts in my threads)
During his research on Jūgo's clan, Orochimaru eventually tracked down the source of their power when he discovered the Ryūchi Cave and senjutsu. It is assumed that here he was trained by the White Snake Sage in senjutsu and attempted to learn how to use Sage Mode. However he was unable to use this power to its full potential due to being unable to find a host body that could bear such an ability, making it an unsuitable option for battle altogether. But! after absorbing Kabuto's full knowledge of Sage mode, add to that a body more than capable of harbouring the curse mark (Possibly suspending sage mode indefinitely), that has the younger son's cells (That is also the First's clone, can you find a body more capable?)and Mokuton in it, throw in four Edo Kage (One of which happens to harbor half of the nine tails chakra) and Zetsu's spore cloning ability and,well ****, I feel sorry for anyone in this guy's way.
All of this is in Orochimaru's hands, he definitely seems to hold most of the cards and we haven't even seen the scope of what he could do before he lost his arms. The spore cloning ability practically makes him unkillable (Imagine hundreds of Orochimaru clones), along with the fact that Zetsu can absorb chakra and give it to others. It's quite coincidental that Kabuto has the one sure fire thing to kill him as he stands now, Kabuto states that he crated a drug that could baisicly destroy Zetsu and...oh Orochimaru appears to of just hopped into one!
I kinda think that Kabuto will be Orochi's end.
Any counter arguments or just general input to my theory?
