On the revived Toonami on [adult swim], the original Naruto was given uncut reruns starting in late 2012. Not much of a problem. In late 2013, it was announced that the show would be leaving and its sequel show, Naruto Shippuden, would be taking its place. However, when the production crew behind Toonami revealed the January 4th lineup, it turns out that not only is Shippuden airing, but the original will be staying, rerunning the first 52 episodes at a later timeslotnote the production crew stated that this is because Viz gave them a choice of either continuing the original Naruto, or picking up Shippuden and rerunning the original Naruto.
Beam Me Up, Scotty!: Tobi didn't say "Tobi is a good boy," Zetsu did. As well, a translation error by Sleepy Fans has Sasuke claiming that he wants to kill all five Kages, instead of just Danzo.
Kishimoto's early concept (and the series pilot) live in a completely different continuity from the series as we know it today. Originally,
While still involving jutsu, Naruto took place in an Urban Fantasy setting, including modern fashion and technology, and there was no trace of a "hidden village" to speak of. The pilot featured a gun, a motorcycle and a murder investigation by the regular, Muggle police.
Naruto (the character) was actually a reincarnation of the nine-tailed fox, rather than having had the fox sealed in him (throughout the pilot chapter, a cover story is perpetuated where Naruto is the fox's son). Also, the beast was sealed away not by the 4th Hokage, but by "9 powerful men", of which only one survived - a grumpy old man of high standing which Naruto refers to as "chief", and is obviously a precursor of the third Hokage.
The cast was very different. Most of the important characters from the pilot never appear in the series proper, and vice-versa. The closest we have to an exception to this is early concept art, which featured Ichiraku from the Ramen shop; the above-mentioned character very similar to the 3rd Hokage; Kakashi (sans his lazy eye); Iruka (sans his ponytail or scar); Hinata (wearing a modern dress and wristwatch); Ibiki and Anko. It is not known which other characters were planned originally, but it is explicitly known that many were not. In the first databook interview, the author relates how he felt the story "wasn't going anywhere", so he went to his editor for help and was advised to introduce a rival for Naruto - which ultimately led to the introduction of Sasuke, Sakura and most of the rookies.
If it wasn't for a mandate by his publisher, the author would have never shown Suigetsu or Juugo fighting on-screen.
There are rumors that Hidan originally had a more complicated set of abilities planned, but editors thought it would be a better idea to cut that fight short and get to Sasuke earlier; and that Tsunade and Pain were supposed to have a more serious fight, but it was scrapped so Naruto's arrival could be the last chapter of the year.
Narutimate Accel 2, what would have been known as Ultimate Ninja 5, has been confirmed to be out in the UK, but will not be coming out in the USA (or so says tens of thousands of forum-ers and a semi-official statement, versus a scant few hundred clinging to false hope)
Because of the "Quality" of their edits in the first few seasons, Jetix UK never did air the later Seasons of Naruto or anything of Naruto Shipuuden.
It doesn't take a genius to figure out that Naruto is the son of the Fourth Hokage, which is something that's common fact for the entire audience. How people in-universe haven't realized this when it's so obvious is still left unanswered.
Tobi being Obito had been a fan theory circulating for years, until it was proven right in Chapter 599.
Zetsu being involved in Obito's survival had also been guessed several years before .
Almost somewhat of a subversion though. Tobi being Obito was considered by many fans to be so obvious they disregarded the idea outright as way too obvious for the author to do.
Another theory that had been pretty popular for quite a while and also confirmed to be true was Naruto and Hashirama being reincarnations of the Younger Son while Sasuke and Madara being reincarnations of the Elder Son.
In the Mexican Spanish dub, Besides voicing Hayate Gekko, Irwin Daayan also voices Kurama of all characters. Keep in mind in Mexico, he's normally type-casted on voicing pretty boys or Hot-Blooded heroes, and while not the first time voicing characters with deep voices (like Mugen or Tetsu Hayami), maybe it's one the few times he voiced a villanous role, at first.
Star-Making Role: Most of the Los Angeles-based voice actors can, due to the massive popularity of Naruto in the US, claim their role as their best-known. The main exception is Kyle Hebert who is still best known as Gohan. Yuri Lowenthal in particular got really popular after voicing Sasuke.
Trolling Creator: In terms of shipping, you bet your ass he is. Mostly towards the NaruHina and NaruSaku fandoms. The list goes:
Hinata confesses to Naruto. Which Naruto then IGNORES for the rest of the manga so far. He later recalls the events leading up to the confession, but does not address the confession or his answer
Sai tells Sakura that Naruto is in love with her, which causes Sakura to confess to Naruto. Naruto thinks she lying and refuses. Turns out she was and is still in love with Sasuke
Naruto meets his mother, gives him tons of advice including telling him to find a girl like her, cue Ship to Ship wars over who is more similar Hinata or Sakura. When Naruto digests his mother's advice, he happens to ignore the shipping related part.
Chapter 615 has Hinata personally pulling Naruto out of the Despair Event Horizon and they are holding hands, making most of the fandom think NaruHina is canon. Then 631 came out, REVERSING that moment by revealing that Sakura is the one similar to Kushina, given by Minato himself, and Naruto calling Sakura his "more or less girlfriend" in front of his father. And Hinata generally going back into the background
Chapter 662: When Naruto is taken to Sakura so she can heal him, which Hinata sees with her Byakugan. She rushes to Naruto, only to trip and faint. While Naruto and Sakura are taken away by Gaara.
Nonshipping related matters include during 660 he had Madara extract Kurama from Naruto. This was during the holiday week, but for Americans it came on CHRISTMAS. And then we had to wait three weeks for the next chapter.
Or chapter 674, Kishi released 13 pages before the chapter came out. We find out, he pulled a huge wham chapter in the 4 pages remaining. In which Madara steals Kakashi's Sharingan and enters Obito's alternative world with an exhausted Obito and Sakura alone with him. And it was a double issue, so we had to wait 2 weeks for the next chapter.
Truth in Television: Somewhat. Chapter 622 says that during times of war in the years when the First Hokage was still a child, the average life expectancy of a shinobi was less than 30 and that this was because of high death rates for children. In Real Life, until modern medicine came about in the 1800's, the average lifespan was significantly lower than it is today. However, this is because infants and young children, whose bodies had not yet developed strong immune systems, were susceptible to diseases and often died. For thousands of years, the average death rate for pre-pubescent children was one in three. Once you reached puberty, though, you were likely to live almost as long as you would now.
All of the Akatsuki members, notably, were originally intended to resemble monsters with little-to-no human qualities at all, and some of them (particularly Itachi and Kisame) likely only had more sympathetic qualities added with time - this is especially true of the inhuman-looking Kisame and Zetsu (who've always been that way, from what we see), and can also be seen with Kakuzu, Sasori & Hidan (who all mutilated themselves for power, in the process losing their humanity), as well as Deidara with his hands. Even Itachi, Pain and Konan have elements of this, more specifically with their abilities (Itachi with his eyes, Pain with his multiple bodies, and Konan with her ability to turn into paper).
Kishi has revealed in a recent interview that he intended to write seinen when his shounen one-shots kept failing, but his editor convinced him to try one last time before trying for seinen. This last try led to the Naruto manga.
Naruto was supposed to be a Goggles Do Nothing shonen hero, but the creator found the goggles too tough to draw consistently so he changed it to the ninja headband. The headbands would then be expanded to a cultural motif for the Ninja World and almost every character wears one.
Writing by the Seat of Your Pants: Inevitable, given the schedule constraints of a weekly chapter and there is no way the author could have planned everything Ten Years in advance. Unlike some other manga writers, Kishimoto rarely pauses for research, and it shows. A lot of turns of plot involve a Retcon in some capacity; a lot of apparent contradictions, plot holes and Ass Pulls make more sense when you adopt an out-of-universe perspective.
Itachi was originally intended to be the Card-Carrying Villain we all assumed he was; the idea of making him into an Anti-Villain only occurred to the author later (and definitely no earlier than that part where he mentally tortures Sasuke, ostensibly his beloved younger brother all along, for 24 consecutive hours).
Comic relief Tobi, Madara-Tobi and Obito-Tobi are evidently three different characters that the plot required at different times, sewn together into a single character on demand (respectively: a comic relief, a Big Bad because Pain was about to exit stage left, and someone with emotional significance to the protagonists so the final battle would have some emotional gravitas).
The Kyuubi was the only "tailed beast" planned initially, and the rest were conceived later. (when introduced, Shukaku was stated to merely be a being similar the the Kyuubi, and no one seems to know what a jinchuuriki is, when later it's a major cultural institution that played a major role in keeping the international power balance).
During the height of Madara's reign as ultimate villain, Kishimoto outright stated that he doesn't know how he's going to have him lose. His solution was to have him stabbed in the back by a Giant Space Flea from Nowhere; now it's not clear how THAT villain is going to lose.
On fanfiction.net, Naruto has by far the most fanfiction pieces of ANY anime or manga (over 330,000), more than three times as many as runner-up InuYasha. The only property in any medium with more fanfictions is Harry Potter, making Naruto the second-most popular subject for fanfiction in the world.
To meet the 600 billion quota, she would need to produce 228,159 paper seals every second for 1 month. That's 13,689,546 paper seals every minute; 821,372,779 paper seals every hour; And 19,712,946,700 paper seals every day for one month.
In 2007, all the newspapers in the world only sell about 395 million copies per day (55 million in the U.S).
Assuming Konan's paper seals have the same dimensions as a standard playing card (63 mm x 88 mm), 600 billion paper seals would have a surface area of 3,326 kilometers squared. New York City has a surface area of 790 kilometers squared. Konan's papers could blot out the sun in New York City four times over.
A standard 52-card deck weights 94g. 11,538,461,500 decks could be made from Konan's paper: weighing at a total of 1,195,583 tons.
One ton of non-recycled office paper uses 24 trees (each tree 40 feet tall and 6-8 inches in diameter). Without ninja magic, 28,693,992 trees would have to be slaughtered.
The typical thickness of a playing card is 0.25mm. If Konan were to stack up all her paper, it would have a height of 150,000 kilometers. The diameter of Jupiter is only 142,984 kilometers. It would take a stack of over 11 Planet Earths to reach 150,000 kilometers.
The total volume of the paper at 831,600 cubic meters exceeds the volume of the BP oil spill at 4.9 million barrels or 780,000 cubic meters. Konan's papers could soak up the BP oil spill.
Konan's attack produced one billion explosions per second. If the amount of energy released from one of those explosions is equal to just one gram of TNT then the amount of energy release per second is equivalent to 1 kiloton of TNT. The total amount of energy released from the 10 minute onslaught is equivalent to 600 kilotons of TNT, which translates to 0.6 megatons. To put this into perspective:
The Little Boy atomic bomb exploded on Hiroshima with an energy of about 15 kilotons of TNT.
The highest yield nuclear weapon ever detonated was Tsar Bomba, at 50 megatons.
The variable-yield B83 nuclear bombs in the current US arsenal have a maximum yield of exactly twice this estimate of Konan's total assault, at 1.2 megatons.
This chart of nuclear weapon yields suggests that this estimate of Konan's assault would carry a total yield of somewhere between the Ivy King and the B83.
Supposing four tags are the size of one book's leaf of paper, bound in sets of 200 leaves (400 pages), that's 800 tags per book. Squeeze those on to double sided bookshelves, eight shelves high, eight books per foot. Konan filled a library building, ten stories high, each story having twenty-two quarter mile long shelves. Imagine every sheet of paper in the French Bibliotheque Nationale exploding four times.
It would be simpler if Konan had some kind of doubling power where she could split paper bombs into double the number of equal sized paper bombs with a fixed input of time and chakra. If she had, starting with a single paper bomb she would only have to employ this jutsu ceiling(lg2(6,000,000,000)) = 33 times. Then again, the implications of allowing such a jutsu to operate without bound are catastrophic- even according to the highest estimate, it would only take 186 applications of the jutsu for the mass of produced paper bombs to exceed that of the observable universe.
Mifune is named after Toshiro Mifune, famous for his portrayal of samurai in movies of Akira Kurosawa. Interestingly enough, the name of his sword is Meifou Kurosawa.
Every time two Akatsuki members fought, an Uchiha was involved and won.
Naruto and Gaara have a lot in common, their father is the Yondaime and their mothers died after they were born, their hobbies deal with taking care of plants (Naruto: gardening, Gaara: taking care of cactus. By Shippuden they're the same size (height and weight). Also they both want to fight Sasuke. Also if you add the Month and Day of their birthdays you get 20. They were also made Jinchuuriki when they were babies.
Word of God says this was intentional to make Gaara as the Foil to Naruto. And if that's not all, their fathers as well as the events of meeting their fathers also play out very similarly to each other.
The Third, Fourth, and Fifth Kazekage have all had some variety of telekinetic control over sand—the Third with his Iron Sands, the Fourth with his Gold Dust, and the Fifth (Gaara) being...Gaara. (It's almost like they pay attention to terrain advantage or something.)
Deidara is the only known person who was alive and fought a living Kage straight up and won, Gaara in his own village: What happened between the Third Kazekage and Sasori is unknown, The Fourth Kazekage was slain by Orochimaru in an ambush, the battle between The Third Hokage and Orochimaru was a draw at best (if because Orochimaru wasn't trying as hard as he could have), Minato defeated Tobi, but gave his life to seal the Kyuubi in Naruto and Danzo wasn't officially sworn in.
Mitarashi Anko is the name of two types of dango. Ain't that funny?
Hinata's big Throw the Dog a Bone moment (chap. #615) came out on the week of her birthday, December 27th. (Fans following early leaks/scanslations got it exactly on her birthday, but that's probably a coincidence.)
