Pain isn't going to die, because of his Imortality no plot ..
Just like Beatrix~
I wonder how many hi-pots jiraya still has
"Chile is a thin and tall country"
OMG I just realized something. Naruto may be copying Bleach because Orihime and Tsunade both have big jumbies. Pwnt.
Seriously, with all the plot stuff going on, I'm sure Kishi decided to steal from popular books and manga, just to see if a young Sherlock Holmes-in-the-making like yourself can detect it and pretend you're smart.
Buy my Book!
its a shonen manga, odds are there will be plenty of big boobed hotties.
Or maybe pain killed everyone he used to like except konan cuz shes not strong enough or they are blood related i dont know getting back to the point he probably just got their bodies rebuilt them put plugs so that they could be "one" then used some weird ninjutsu so that they could be together discarding his real body and having a totally different personality cuz he is 6 people and then hes here now being Pain.
so to sums up ur point, its pretty much what orochimaru has been doing...except with 6 body at the same time...but he also had to split his abilities to each of the body. so its pretty gay, actually. might as well do what orochimaru does, and then use kagebunshin. 6 handicapped dude is not better than 1 fully function dude to begin with.
I think its smart to split them into 6 bodies. He have mastered all the Techs. so why not having 6 Rinnengan that uses the Techs. at the same time.
the six bodies are each supposed to represent one of the traits of each of the 6 spots in the reincarnation wheel. example summons equal animal(most summons are animals after all), absorbing chakra based attacks equals demons in hell(both are devourers) things of that nature. Even if they are similar to the things from Harry Potter(not a fan of this series personally and I don't agree with this opinion), they probably just had the same original inspiration somewhere since J.K. Rowling is pretty notorious for lacking originality. For HP's fans that pisses off, please go look it up before you try to whine about my comment being unfair to Rowling.
^I don't know where you're getting this from. Sure, ninjutsu ~ wizardry and Orochimaru ~ Voldemort, but the rest seems off. Also, the origins of the allusions the stories are completely different.
