What would truly make Kishi a troll is giving no signs or hints throughout the Naruto series of Tobi being Obito and then at the last second pulling it out of his ass, this would be unacceptable because if you want to give your fans the chance to make theories about a secret you are keeping you have to give them some signs.
But actually as a writer it is your choice whether you give or not give any signs/clues of a secret you are keeping in your story. Normally writers tend to give clues that lean towards other characters to distract them from the truth.
Let's start off with the first ever hint which ironically became the last:
A masked boy appears out of nowhere and takes out the deadly zabuza like he was nothing, a nice clean assassination. But the question on everybody's mind was who is this masked boy ?? Kishi opened the next manga chapter with this page:
As you can see the manga chapter is called who are you? Strangely enough Kishi opens with a scene with Kakashi asleep and if we look carefully in the background we can see two pictures one of team kakashi and another one which is the first ever look we get of team Minato. Funny that Kishi would give the first sighting of Obito in a manga chapter called “who are you” which a mysterious masked person has appeared in the manga.
Most of us missed this hint because we did not start reading the manga at this time, but anyway there is the first link to Obito being the masked man.
Anyway the way Haku was unmasked the end of this masked boy mystery is Identical to the way Tobi was unmasked as we can see below:
But funny enough the words Naruto said as he unmasked Tobi is the exact title were people first would of laid eyes on obito which is the manga chapter called Who are you, as you can see kishi has connected all these events which is Ironically the first and the last hints we were ever given.
I notice Kishi say this a long time ago but I didn’t take it as anything, he says the wish is “entrusted” that is a very big key word to Tobi:
The chapter title of the chapter we first ever saw Tobi was called “Entrusted Feelings”
When Naruto mentions the word entrusted Tobi laughs at those words:
and askes Naruto a serious question, what if you fail the mission others has entrusted into you. How will you feel about yourself?:
Naruto himself has no answer, from watching Tobi recently we could see this was his biggest problem with the shinobi world. No matter how bad someone can want something to be true or to prevent something that does not fully assure that want they want will be achieved and what they want to prevent will not happen. Tobi wants to created a world where people can stop getting disappointed by failing their mission for peace and failing what people have entrusted onto them.. Infinite Tsukuyomi
has never meant anything to me and I have never considered this to ever really be a hint from kishi about who Tobi is. All we can do with hair is just confirm things for example, the first "event" tobi has ever done that we have seen tobi had short hair.
The second events we have seen tobi do he had long hair and this was when he revealed him self to kisame for the first time and when he spoke with itachi. We can tell these two events are close to each other because of hair length and outfit. These two sightings of tobi where around 8 years after the kyuubi incident so his hair being long is understandable if he left his hair to grow.
Tobi has sharingan in his right eye:
Funny enough kakashi was the first to notice this (you will notice kakashi is most of the time always around when something is found out about Tobi that in itself is a hint)
Having a sharingan in your right eye means nothing, many shinobi implant sharingan and byakugan’s into their eye sockets, kishi used this knowledge to get rid of the thought that because Tobi had a sharingan in his right eye he could be obito.
The hint about Tobi’s sharingan was that it’s abilities were very similar to the left eye Kakashi has in his left eye which he obtained from Obito
As we know Tobi can warp anything he touches into different dimensions.. as well as himself to different dimensions and other locations:
And kakashi can warp anything he focuses his eye onto into different dimensions:
These are the only two sharingan’s with S/T in the series the fact that kakashi has his in his left eye which he obtained from Obito and Tobi having his in his right eye is a direct hint that the eyes are both obito’s logically hinting that tobi is Obito.
This hint about kakashi knowing there is something similar about Tobi’s was strengthened by this scene:
Kakashi and Tobi meet up once more:
but the way Kakashi talks to Tobi suggest Kakashi himself had doubts about Tobi being “Madara”:
Kakashi in this scan was trying to confirm that Tobi is who he says he is we can see that by how he says it and him saying so you admit it: This is hints that something is fishy about Tobi being madara.
Tobi as we know is a good actor because who he said he is, is being doubted he makes many references to Hashirama which logically is something Madara would do as they are from the same time and he was his rival, Tobi played everyone even us as readers.
With all the links about similar abilities they are strengthen even more by this scene
Tobi tells Kakashi there is no point in even trying to use Kamui on him.
Tobi’s body is one of the most messed up bodies in the series which is what you would expect by someone who had been crushed by a big rock who’s else body would be this ****ed up in the series:
And we already knew all that white goo was zetsu:
Having zetsu in you or not for you to be able to painlessly rip of limbs at will means you must have received heavy damage to that part of the body.
We haven’t heard Obito talk much and by that I mean when he is serious and not joking around but here I will show you some hints in Obito’s speech that are hints to him being Tobi
This is a scene when Obito is angry so his true feelings is coming out now
He says him are Kakashi are like water and oil (which means they cannot mix) that is a phrase Obito used to describe him and Kakashi:
When Tobi is talking to Sasuke and he is explaining how the Uchiha and Senju could never get along he describes their relationship to be like water and oil. Which is the exact phrase Obito use to use:
This is a random one
Also read these two bottom panels:
These are some serious words from Obito which came out when he was angry saying he will break the rules and crush that idea of "Shinobi".
Tobi and Kakashi (funnily enough) meet up again but something is seriously bugging Tobi we can tell by his eyes and how the panel randomly switches to him:
Instead of him saying good eyes he says good eye which means he is obviously referring to Kakashi’s sharingan:
This was an obvious indirect to Kakashi having Obito’s eye which you would know as it has been my Sig for ages
Once again what Kakashi does seems to anger Tobi as we can see once again by his eyes and the panel randomly
switching to Tobi:
Now those were all the not so obvious hints of Tobi being Obito that Kishi has left throughout the whole Naruto series. The next hints after these are more obvious as Tobi being revealed was right around the corner and was needed for build up and so they could be used for things such as flashbacks and what not. But anyway here they are for the sake of the thread:
Tobi saying Kakashi has always opened his mouth so easily directly implies that Tobi knows Kakashi and that Kakashi has said things that he has never been able to back up or accomplish:
Most likely Obito was talking about these things that Kakashi has said:
These are very big promises and maybe kakashi shouldn’t have promised such things that there was no way of telling if he could actually do this.
Tobi meaning those words kakashi has said above when he said that Kakashi opens his mouth to easily is back up by this scan:
Words and no action (all the promises his made he had failed them) which means what he says and promises has no meaning to Tobi
This implies Tobi and kakashi’s eye is both Obito’s eyes:
A world where heroes don’t have to make apologies in front of grave yards obviously referring to Kakashi:
Not afraid of some Borrowed power, this would mean that Tobi’s Kamui is not borrowed and is his:
This is backed up by him saying “The real Kamui”:
Ok so that’s all the hints I have found that Kishi has left in his manga, so with all these hints how can you say Kishi making Tobi obito is a troll? As I have shown you Kishi did not pull this out of his ass he has planned this since the beginning.
