Jiraiya

was one of the legendary Sannin, along with Tsunade and Orochimaru, who was trained by the Third Hokage himself. He is a self proclaimed mega-pervert, and writes popular adult book series called Make-Out, a favorite of Kakashi Hatake. He is also known as the, because of his signature toad summonings. Jiraiya has the kanji for "oil" on his forehead protector. He was the Fourth Hokage's teacher and then later Naruto's, who calls him "Ero-sennin", or in the English anime, "Pervy Sage". He proved this in his childhood when he peeped on Tsunade in the baths, resulting in him being beaten to an inch of his life.

Despite his perversion, Jiraiya is a Kage-level ninja. During a war, the team consisting of Jiraiya, Orochimaru and Tsunade came to battle "Salamander" Hanzo of the Rain village. Hanzo was so impressed that they survived the attack that he gave them the title of Sannin, the legendary three ninjas (which he ordered they refer to themselves as an exchange for fighting Konoha any further). In his early years, Jiraiya invented the Transparent Escape Technique to help him peek on women and not get caught, though Naruto occasionally blows his cover.

Background
As a child, Jiraiya and his former teammates, Orochimaru and Tsunade, were students of the Third Hokage. After leaving the Third's tutelage, he traveled the world and discovered the residence of the toads, a species he proved to have a natural affinity for. During this time, Jiraiya is told a prophecy concerning him and his students, which states that they will decide the fate of the world. Once returning to Konoha, Jiraiya and his former teammates were forced into battle with Hanzo as a result of an ongoing war at the time. When they proved able to survive his attacks, Hanzo rewarded them with the title of to indicate their status as the strongest ninja in Konoha.

Once the battle was over, Jiraiya encountered three orphans from Amegakure; Konan, Yahiko, and Nagato. He looked after them for a time and taught them Ninjutsu before leaving them so that they could pursue their own goals. Although news of their exploits reached him from time to time, he thought them to have died during an undisclosed incident. Presumably leaving the three, Jiraiya began to travel the Naruto world and write his book.

Once becoming a Jonin capable of leading a squad, Jiraiya became the teacher of Minato Namikaze and two other unknown Genin. Years later, when Orochimaru betrayed Konoha and fled the village, Jiraiya pursued him, trying to convince his friend to come back. Orochimaru refused, and attacked Jiraiya. While he tried to find a reason for Orochimaru's defection, he eventually realized that his friend wasn't coming back. Feeling he was responsible for Orochimaru's escape, Jiraiya left Konoha so he could follow Orochimaru's movements as well as the organization Orochimaru eventually joined, Akatsuki. In doing so, Jiraiya was unable to fulfill the Third's wishes of taking on the role of Hokage, knowing that tracking down Orochimaru was more important. A few years before Orochimaru's defection, Jiraiya finished his first book that had failed as a seller. Minato, now the Fourth Hokage, however thought the book was excellent, he and Kushina Uzumaki decided to name their son after the main character in his book, Naruto, thus making him Naruto's godfather.

Personality
Despite the fact that he left Konoha for many years, Jiraiya has maintained a strong allegiance with his hometown. During Orochimaru's invasion of Konoha, he helps fend off the invading forces in order to protect the village. When Konoha finds itself in need of a new Hokage after the Third Hokage's death, despite turning down the offer to fill the rule, Jiraiya volunteers to look for Tsunade so that she can become the Third's successor after turning down the position himself. His reason for refusing the position is, among other things, that he feels unworthy to take the role since he failed to save either of the previous Hokages from dying. After he finds Tsunade and begins to suspect that she may be assisting Orochimaru, he makes it clear that he will kill her if she betrays the village.

Jiraiya is a self-proclaimed super-pervert with no equal and a frequent voyeur, going so far as to create the Transparent Escape Technique to allow him to spy on naked women without being caught (doing "research" as he calls it, even as a child). He never actually hides his perversion and even seems proud of it, as seen when he told the Third Hokage about it when he was still a child. Despite this, Jiraiya doesn't like being called by Naruto Uzumaki in front of others.

Jiraiya's perversion has been used against him on occasion's, as seen when Naruto gets Jiraiya to start training him after a simple display of the Sexy Technique. When two Akatsuki members later try to distract Jiraiya, they use a hypnotized woman to catch his eye and keep him busy. While their effort initially succeeds, Jiraiya eventually sees through their plot due solely to the fact that women do not typically express interest in him. His peeping habits have also caused him great injury on one occasion; when caught spying on Tsunade in his younger years, she proceeded to break both of his arms, six of his ribs, and ruptured a number of organs as punishment.

Some time after leaving Konoha, Jiraiya became an author of adult novels, his most popular work being, a personal favorite of Kakashi Hatake. The novels are based on his rejections in love that he retells in a comical way. In a filler episode of the anime, Naruto ghostwrites one of Jiraiya's Icha Icha novels and the book is found to be very popular, indicating that Naruto is capable of writing on the same level as Jiraiya, or that Jiraiya's writing abilities are no better than those of a child. Tsunade seems to suspect that the latter is true, as she notes that a report on the Onbaa he wrote as a child, accompanied by crude crayon illustrations, was poorly written. The popularity of the Icha Icha series seems to have paid off well, as Jiraiya's checkbook reveals that he is fairly wealthy. Despite his wealth, Jiraiya is not above taking Naruto's money and spending it on sake and women, and frequently disappears when Naruto attempts to make him pay.

Jiraiya has also been known to show off even during a fight. This showing off typically takes the form of traditional kabuki poses, keeping with his hermit theme. He becomes annoyed if he is interrupted for whatever reason while trying to strike a pose.

Jiraiya can become extremely serious in battle or when he is about important business (i.e like when Naruto says he wants to give himself to the Akatsuki) and also often has a serious voice in his head but he never says what he is thinking or discusses important matters with another person. He can also be quite perceptive, as seen when Naruto tried to walk over the surface of shallow water with Jiraiya as audience; Jiraya quickly discerns that there was something within Naruto that was disrupting the chakra's circulation around the boy's body, leading him to undo Orochimaru's Five-Element Seal

As mentioned above, the Kanji on Jiraiya's headband means "oil," but in Mandarin Chinese, it also means "sly". So it's a bit of a double entendre for both his abilities and his personality.

Chunin Exams
Jiraiya first meets Naruto Uzumaki while he was "researching" at the hotsprings in Konoha, where he flattened Ebisu when he almost exposed him. Because he knocked out his teacher, Naruto demanded Jiraiya to train him, which he initally refused. It wasn't until Naruto used his Sexy Technique did he win Jiraiya over.

When they start training, Jiraiya removes Orochimaru's Five Elements Seal off the boy's stomach which allowed him to tap into the Demon Fox's chakra thus allowing him to use better jutsus and mold his chakra with ease. For special training for the last part of the exams Jiraiya taught Naruto how to use the Summoning Technique, but was met with very poor results. To this end, Jiraiya decided to force Naruto to use the Fox's chakra, by pushing him off a cliff. After Naruto survives this training and summons Gamabunta, Jiraiya stays in Konoha for the events to play out. When Orochimaru and the Sand attacked Konoha, Jiraiya appeared with a giant toad to help battle one of the Sounds summoned snakes.

The Search for the Fifth
After the death of the Third, the village elders, Homura Mitokado and Koharu Utatane, requested that Jiraiya become the next Hokage, which he quickly turns down. Instead he volunteers to search for his former teammate Tsunade, and took Naruto with him for more training. Jiraiya would train Naruto to use his father's technique, the Rasengan.

Before they could reach Tsunade, Orochimaru contacted her in an effort to have his dead arms fixed by Tsunade's medical jutsu. Tsunade, deciding to meet Orochimaru herself, drugs Jiraiya's sake and heads out on her own. When Jiraiya, Naruto, and Shizune catch up with her, she is already in battle with Kabuto. Jiraiya goes into battle with Orochimaru, trapping Orochimaru's snake with his Underworld Swamp jutsu. Although the weakened jutsu fails to envelop the snake completely, it is still more than large enough to immobilize it. After Naruto takes Kabuto out of battle with a now-perfect Rasengan (made with the help of a clone, an innovation he came up with mid-battle), Tsunade joins Jiraiya in the battle against Orochimaru. With their ultimate summons, Gamabunta and Katsuyu, the two take on Orochimaru and his snake Manda. The healthy Tsunade proves too much for Orochimaru and Manda, defeating the two and causing them to flee. With Tsunade now accepting her post as the Fifth Hokage, they return to Konoha.

Sasuke Retrieval
Jiraiya apparently witnessed Naruto's brief fight with Sasuke on the rooftop. He then debated with Kakashi about teaching Sasuke the Chidori, which Sasuke could have killed Naruto with. In turn, Kakashi said it was irresponsible of Jiraiya to teach Naruto the Rasengan. Jiraiya was planning on having a talk with Naruto about his and Sasuke's unhealthy rivalry, but as Naruto walked past him he couldn't bring himself to say anything for whatever reason. Jiraiya wasn't in Konoha during Sasuke's defection and reappears only after Naruto returns after failing to bring him back. Jiraiya reveals that Sasuke and Orochimaru are very similar, in that both only lust for power and both will do anything to get it. In fact, Naruto's battle with Sasuke was very similar to Jiraiya's fight with Orochimaru when he tried to bring Orochimaru back, trying to remind his friend of their past friendship. When Jiraiya called Naruto a fool for even considering trying to rescue a friend like that, Naruto tells him he would rather be a fool than to give up on Sasuke. Taken aback, Jiraiya tells him that once he is better, he will take him to train for three years so he will be strong enough to bring Sasuke back, and protect himself from the Akatsuki.

Part II
After taking Naruto back to Konoha, Jiraiya goes off to search for info on the Akatsuki. Jiraiya would reappear later to inform an injured Kakashi and inform the current leader of Team 7, Yamato about Naruto's four tail transformation, a form so powerful that it nearly killed Jiraiya before he stopped it. It is later revealed that Jiraiya himself released it (not expecting Naruto's loss of control) with a special key passed down from the Fourth Hokage, capable of unlocking Naruto's seal. Jiraiya appears again to inform Naruto and Sakura that Sasuke has killed Orochimaru and is most likely going off to kill Itachi, before doing more research on the Akatsuki.

Infiltration of Amegakure
Jiraiya later returns to Konoha once more to inform Tsunade that he has found the location of the Akatsuki Leader, somewhere in Amegakure. After a chat with Tsunade revealing much of Naruto's history, he heads out to the Rain country. He infiltrates the village using a particular frog with a jutsu that warps in size and begins interrogating two ninja he abducted in that same frog. There is no initial response, but he is immediately spotted by Pain's rain jutsu. Upon learning that Pain singlehandedly defeated Hanzo, he summons the frog containing the key to Naruto's seal, and informs it to go to Naruto if he dies. Rather than wait for Pain to come to him, Jiraiya prepares to do battle (to forcibly extract the information).

After fighting with Pain for some time, he claims to have discovered his true identity. However, Pain's thorn-headed body is able to attack Jiraiya by surprise, allowing Pain's other bodies to thrust their four black blades into his stomach. As he dies, Jiraiya recalls his view on how the measure of true shinobi is not just how they live, but how they die. He recalls his life as one full of failure, since Tsunade turned him down every time he asked her on a date, he wasn't strong enough to stop Orochimaru, and failed to help Minato, as well as the Third. However, he always thought that his failures were building character, and that he would be granted one, final adventure. However, he failed to stop Pain. He thinks that his story is pathetic, and that writing it was a waste of time. However, he remembers how Minato actually enjoyed the story, and that he and Kushina decided to name their son Naruto, after the character in Jiraiya's story, making Jiraiya Naruto's godfather. He then realizes that his point in life is encouraging others to do their best, and to never give up. He forces himself back to life with willpower, and transfers the information about Pain to one of his toads. He believes that Naruto is the child of prophecy he heard in a prediction by the Toad Sage. As Jiraiya's toad escapes to Konoha, Jiraiya sinks to the watery depths of the battlefield, while stating that this ending for him is a lot better than he thought he could achieve. His death is later confirmed by the toad Fukasaku.

Abilities
Being one of the Sannin, Jiraiya is an immensely powerful ninja. He states that he has only been brought to the verge of death twice in his life, once when he was doing "research" on Tsunade and when he used the toad key to "twist" Naruto's seal unleashing his Four-Tailed Transformation. His strength is such that Itachi and Kisame, two of the most powerful members of the Akatsuki, opted not to face fearing that it would end in their deaths. Kisame even says that Jiraiya's skill and power far outclass his own. Another example of his extreme power is shown when he is battling Pein, leader of the Akatsuki and an extremely powerful ninja. In his hermit mode, he is shown on equal footing with him and possibly would have won if he didn't let his guard down after he trapped the three bodies.

Jiraiya is known as the "Toad Hermit" due to his utilization of a number of toad-related jutsu. Many typically deal with summoning toads, and he has risen to a level of ability that allows him to summon Gamabunta. He can even summon the nearly indestructible esophagus of a great, fire-breathing toad with Summoning: Toad Mouth Bind. Once the jutsu has been used to cover the area, Jiraiya can control it as he pleases and use it to trap most ninja. In desperate situations, Jiraiya is able to switch into Hermit Mode. Though it enhances his power and transforms his body, he had yet been able to utilize the technique on his own, so he must summon two elder toads to assist him in battle, and contribute by using their own techniques. It is interesting that while normally Jiraiya speaks in a carefree manner and has a somewhat idiotic disposition towards others, he is very polite towards his toad summons.

In addition to calling upon toads for aid in battle, Jiraiya has a large number of jutsu he can use independently. His Earth Release: Swamp of the Underworld creates a special swamp on a surface of his choice, which can be as large as a lake, and is seemingly impossible to escape from with brute force. He can utilize a number of fire techniques and Toad Oil Bullet with his mouth. Jiraiya has also been shown to use his hair for jutsu, and can grow and sharpen it to surround him as a shield with Needle Guardian or use it to bind and impale opponents with Wild Lion's Mane Technique. For spying and infiltration, Jiraiya has the unseen Transparent Escape Technique, the Toad Flat - Shadow Manipulation Technique, which allows him to hide himself as a shadow and even attach to the shadow of another ninja to control them, and the Hiding in a Toad Technique, where he hides in the belly of a small frog, which can enter most areas undetected. Jiraiya was taught how to use the Rasengan by Minato, and has since developed larger variants. Apart from his fighting abilities, Jiraiya is able to use barriers, such as Barrier: Dome Method Formation, which allows him to detect all movements within a 50 meter radius, and Barrier: Toad Gourd Prison, which allows him to trap an enemy inside the belly of a small frog-shaped gourd, the inside of which contains a landscape with a lake of stomach acid. He is not, however, suited for Genjutsu, and thus cannot effectively utilize it in battle.

Jiraiya has been shown to be very knowledgeable with sealing jutsu, and has used a number of them throughout the series. When first meeting Naruto, he quickly deduces that the seal on Naruto's stomach keeps the Nine-Tailed Demon Fox sealed within him though also allows its chakra to mix with his own. He later creates a method of suppressing the demon fox's influence over Naruto through the Demon Fox Chakra Seal, which activates by simply coming into contact with Naruto's body. In addition, he can utilize the Fire Sealing Method to contain Itachi's Amateratsu within a scroll for future study.

His most powerful ability, however, is to enter Hermit Mode, a transformation that makes use of natural chakra to enhance all of his abilities by leaps and bounds. Before entering Hermit Mode, Jiraiya summons the two great hermits Shima and Fukasaku, generally referred to as Ma and Pa. In addition to drawing in natural chakra while Jiraiya fights, they add their own abilities to the mix, such as War of Words Binding, a highly effective tracking technique with a wide range, and War of Words Decapitation, a powerful mid-range cutting technique. Hermit Mode greatly increases all of Jiraiya's abilities, giving him superhuman physical abilities, such as enough strength to send a giant bull summon flying, extremely heightened speed, and massive amounts of chakra. In this form, Jiraiya can utilize special techniques, such as Hermit's Art: Deep Fryer, an fire-wind-oil combination attack with Ma and Pa, Hermit's Art: Hair Needle Barrage, a technique where his hair blasts at the opponent like a barrage of needles, and Super Great Ball Rasengan, a massive variant of Rasengan many times the size of his body. Ma and Pa are also capable of using one of the most potent genjutsu techniques in the Naruto world, Demonic Illusion: Toad Confrontation Singing, a sound-based genjutsu which does not activate until the frogs have sung a special song in harmony, but will instantly paralyze and defeat all opponents who hear it once activated. He doesn't like this form because it makes him look ugly in front of the ladies.

Creation and conception
Jiraiya is named after the character of the same name from. The Jiraiya in this story excelled in summoning a giant toad (the toad itself was sometimes called "Jiraiya") and toad magic. In that story, Jiraiya and Tsunade were a married couple. There, his name is written as "児雷也" meaning "Young Thunder" which in turn comes from the name from the Chinese story.

Masashi Kishimoto originally planned to draw Jiraiya with a different design and with a different style of hair. He also intended for Jiraiya to summon Toads that were of a similar size to humans. However, this idea was deemed a failure. During an interview, he comments that, of the student-teacher relationships in Naruto, Jiraiya and Naruto's is the one he likes the most.

Trivia

 * Even though Tsunade is the only remaining Sannin, Jiraiya is the only one that is actually dead as Orochimaru is only sealed.
 * It is unknown if Jiraiya was stronger than Orochimaru as in their last battle, both were severly weakened and therefore could not fight at their full potential. If they had not been weakened and Jiraiya had used Hermit Mode and Orochimaru went into his giant snake form, they might have been equal.
