Obito is the main villain right now, but everything to do with obito has plot no jutsu in it. It's so abundant that kishi makes obito look weaker than he should be. Let's begin.
Don't get me wrong, all naruto's fights are won with PNJ, so he has more PNJ examples, but I find obito is just too cheated out of victory/death sometimes...
Obito vs Cave in
So, we know that obito's right side got crushed by boulders. Just by this, his sharingan should've been destroyed because his entire right side was apparently 'destroyed'. When the second portion of the cave comes down, he apparently 'slips through it'. Now this is what i have a problem with.
So far, we've seen that MS techniques revolve around a superd genjutsu (Itach/Madara - tsukuyomi. Shishui - KA), or a superb ninjutsu (amaterasu), but obito gets a S/T jutsu? Now the real problem isn't that he got the S/T, it's the fact at how convinient it was that; first he actually unlocked his ms there, and second he get's an S/T Jutsu.
This isn't the end of this first portion. With all that heavy damage he still sustained, he should have been killed, but somehow a sickly madara who can't leave his cave was able to save him? Since when did madara become tsunade/hashi tier medic?
Obito Vs Minato
This Fight starts with minato blatantly saying that this guy is dangerous and MUST be killed. Minato even says he HAS to kill him now. So, What happens? Minato slams a rasengan into his back. Obito gets a busted right arm, but survives it with injuries. Now, This isn't where the problem lies, people could tank rasengan. The problem is that obito got tagged.
The next thing minato does is instantly lay a kunai into obito's abdomen. Obito's survived a rasengan and a kunai to the kidney so far ( hardly even possible ). But it's what happens next. Minato let's him get away. Seriously, minato ****ing tagged him. Obito was even surprised when minato kunai'd to the kidney. Why didn't minato FTG blitz him? Why didn't minato use another rasengan? Why didn't minato TRY(even if he fails, but TRY) to follow him?
Minato Says the guy will be a harbinger of death. Minato says he must die. But minato let's him leave without trying to put up a fight? It doesn't matter that the demon fox was on a rampage. Minato could've had time to do one more rasengan.
Obito vs konan
Not much of a big one, but it's the fact that he escaped a fool proof attack....
Now, this one is actually the biggest PNJ i've seen. And it's not even about obito surviving/ what not. It's the entire fight. It's both god damn sides.
The War - Obito vs bee/naruto/kakashi/guy
So, we saw that when rin died, obito unleashed a mokuton fury. I'll get back to this in a minute.
*This will be a bit chopper because i'd have to re watch the war to remember everything, but i'll try*
First, Obito clashes with naruto/bee.
Obito Has a sharingan and 6 paths.
My question is, how did naruto/bee survive? Plot.
Obito Never used Any path of pain, he just let them roam free. Why didn't he use deva path? Or any of the others? Maybe absorb some chakra? Now let's assume he couldn't. The paths still have a sharingan and rinnegan, but never seem to use it's ability. The only ability they show is linked vision, that's the most standard one ffs.
The way naruto/Bee are constantly being smashed, it's just ridiculous, but we see that they're being overwhelmed. So, what happens? Naruto is about to die that's what. But what really happens?

This. How the **** did obito/One of his many paths not see guy/kakashi coming from miles away? They can't teleport so how did they get the jump on him?
But more importantly
You must be registered for see images
this. Kurama is litterally the only bijuu there with reduced power - half to be exact, but yet is able to take on 5 other bijuu at the exact same time without much effort AND is able to make a bijudaama, in a instant, comparable to 5 other tailed beast combined? Ok...
Alright, so we move on past that who naruto is suppose to be dead now, he got rid of the beasts and he's fighting obito. Wait wtf is going on, obito is only using kamui? Wtf happened to his mokuton? We've seen that he's very skilled with it but he doesn't use on bit of it? So, now, naruto and company are holding their own against obito. But, Wait, wtf, how is kakashi using so much jutsu?
During Pain invasion kakashi used; Raikiri, lightning clone, an earth style jutsu, raikiri, kamui And was completely winded, but now he's able to use over 2 raikiri? Over 3 kamui? and other jutsu? How did he get such a massive chakra/stamina boost in no time flat?
Obito is seriously being ****ed out of his win constantly at this point. And it's obviously being done to drag the war fight on longer and longer, it's just ridiculous.
But, Kakashi gets the upper hand on him and sends a clone into his dimension. Obito gets a rasengan to the face and it only breaks his mask, no facial damage. Ok...
Then, kakashi goes into the dimension and only punches him? With such a drop on obito they could have done far more devastating moves. Even a kunai to the kidney would have been better than a gut punch.
Anyway, i'll stop here, because i've been trying to keep this short and understandable but that's hard to do, this is getting dragged on and all i'd be doing now is dissecting the blatant PNJ throughout the war keeping both sides alive...
Tl;Dr Too much plot around obito...
