Orochimaru is undeniably the true villain of Naruto. Satan's serpent has nothing on this man! He is one of the Legendry Three, and is the most talented among them. But since his days of being in the Hidden Leaf Orochimaru has turned wicked. He has formed his own Hidden Village, the Hidden Sound Village which he intends to use an impetus for constant war. Before he can set his "Windmill" [as he refers to it] spinning, he needs to provide it some wind. The Hidden Leaf Village is that wind but why that specific village? Well, Orochimaru has a vendetta with the Hidden Leaf that has lasted a number of years: it stems from his power-struggle within the Hidden Leaf.
Back when he was still an Academy student, Orochimaru was an untouchable child with masses of potential to become a great Ninja. Hokage always praised Orochimaru and thought highly of him, even more than his other students. He was a very bright student and never missed a trick, but there was still something evil about him. His apperance was chilling and he never said much, his eyes usually say it all. Ever since he was small, his physical features were very snake-like. He had a long tongue, small, beady eyes and cold, pale flesh. In fact, he looks more like a snake than a human from some perspectives. As Orochimaru grew, his malice grew with him and he began to act very suspiciously. Some years later, Hokage came to choosing the Fourth Hokage. Orochimaru believed he was the best choice, because he though of himself as the most powerful being in the village. As it turned out, Orochimaru wasn't picked, and the Fourth we know, the one who sealed the Demon Fox, was chosen. This enraged Orochimaru and his bitterness lead to him conspiring to breaking rules and taking it upon him self to plan his revenge against the Third. But his ambition didn't stop of petty vengeance. This is where we see his twisted ideology shine.
10 years before Orochimaru appears in Naruto, he was a very busy man. Taking Chuunin and Genin and even Anbu members, so he could experiment on them in order to obtain a certain Kinjutsu, a forbidden Jutsu, and become the "Ultimate Being". Orochimaru wanted everything. But that, he meant he wanted to know all the Jutsu there was to know. This, seemingly, impossible dream of his would take an eternity to realise. So, to have eternity at your will, you need to become immortal. That is exactly what Orochimaru is trying to achieve. His experiments on Ninja were to see if he could learn the secrets of The Spell of Immortality. It was for this reason, the Third had to stop him. However, the Hokage faltered. His feelings for Orochimaru got in the way when the time came to execute the bastard serpent and doing so, lead to Orochimaru's survival.
In the time Orochimaru was away from the Hidden Lead, he became a step closer to getting immortality. He learned the Reincarnation Jutsu. A Kinjutsu that enables the user to anchor their soul to the living world but requires a new body every so often, so the spirit can endure by possessing that body. This is the spell that allows the Orochimaru cheat age. Had he not learnt this Kinjutsu, he would have looked his true age, over 50 years old. Instead, he is more youthful and beautiful than most of the people 30 years younger than him. It doesn't stop there either. Because he is seeking to learn every Jutsu that exists, he needs something special to hasten the process. And he found the Sharingan. With a body that carried the advanced Uchiha blood in it, he could use the Sharingan to copy any Jutsu that he saw. However, since the Uchina's were bloodily massacred, only two more members exist. and Uchiha Sasuke. One small dilemma hinders Orochimaru. Itachi is a lot stronger than him and would probably kill Orochimaru if he even attempted to obtain his body. Therefore, Uchiha Sasuke is Orochimaru's prey. And he is hell-bent on getting him!
With Orochimaru being one of the Legendry Three, he is able to perform the Kuchiyose no Jutsu! His Summoning beast is Manda, a giant anaconda with an evil tongue, very much like his own. Manda has no weapons, like Gama Bunta, but he does have venomous fangs and extra ordinary speed. This is the only Jutsu of his that's really worth talking about, as most of his techniques have no name. They just involve him using him use his tongue in lots of weird and wonderful ways. Interoperate that however you see fitˇ
Initially, Orochimaru planned to have his condition healed by appealing to his old team-mate, , who has since become a legendary medical ninja. He offered to revive her brother and boyfriend, both of which have died in battle, in hopes this would persuade her to cooperate. At the same time, Jiraiya also contacted Tsunade, asking her to replace the late Sarutobi as Konoha's Fifth Hokage. Though inclined to give in to her weaknesses and accept Orochimaru's offer at first, she ultimately chose to live her loved ones' dream rather than linger on their dead bodies and accepts the position of Hokage, becoming Orochimaru's opposition and leaving him with only one option of replacing his crumbling, useless arms: Transferring to another body through the use of Fushi Tensei.
Though Orochimaru was right about Sasuke after all, and Sasuke does eventually seek him out for power, by the time Sasuke found Orochimaru, he was already in a critical state, the pain in his arms and the constant bleeding reaching the point when soon it wouldn't matter whether Sasuke arrives or not. Desperate for a new body to transfer to, Orochimaru holds a tournament of fights to the death between his prisoners and takes over the body of the last man who remains standing, Genyuomaru. This, while getting rid of his condition, drastically delayed his plans for Sasuke, since he can only take over a new body once about roughly every three years. When he took over him, he also noted that parts of Gen'yuumaru's will and consciousness would remain in the new body's subconscious. It is unknown if he will have to learn his abilities again, or sign another blood contract with Manda (which is a bad idea due to Manda's hostility towards him), or if he has at all been weakened by switching bodies.
It is unknown what Orochimaru had been up to since then for about three years the manga storyline skips, though reason suggests he had been training Sasuke and biding his time until he would finally be able to use Fushi Tensei to transfer into him. Recently in the manga, he is revealed to have been spying on the meeting between Yakushi Kabuto and disguised as Sasori. Orochimaru explains that Sasori's "binding jutsu" on Kabuto had long ago been undone by him, before calling out Naruto, Sakura and to do battle. He explains that Yamato was the only one out of sixty test subjects that survived one of his genetic experiments, to duplicate the 's Mokuton techniques and his previously unknown ability to "control bijuu". Orochimaru demonstrates a number of inhuman abilities during his battle with four-tailed Ky¨±bi Naruto: he can shed his skin like a snake and by doing so, repair any damage to his body, make a large number of snakes and even a replica of himself (apparently also made up of snakes) emerge from his mouth. This clone was able to land a hit on Naruto, and also reform itself after being cut in half at the waist with no apparent side effects. Also in this battle, Orochimaru demonstrates his immense reserves of chakra when he summons three Rashomon gates to block the black chakra ball that Kyuubi Naruto spit at him.
The battle with Naruto comes to an end after Naruto parries an attack from Orochimaru's extended Kusanagi sword. He comments that his body had reached its limits, and says that he must wait for Sasuke's body to come to fruition.
Afterwards, back at Orochimaru's lair, it is made apparent that Orochimaru plans to team up with Danzou and destroy Konoha as it is today. (The wording would seem to indicate a revolution or takeover, rather than outright annihilation.) After a training exercise with Sasuke, he interupts Sai and Naruto after they form a bond to question Sai's loyalty in Chapter 304.
In chapter 305 it seemed like Orochimaru would resume his heated fight with Naruto, but instead he retreated, saying that he would let Naruto go just one last time, in hopes that Naruto and company can take down more Akatsuki members for him.
Orochimaru returns again in Chapter 309; just in time to stop Sasuke from performing a certain jutsu. Kabuto also informs Sasuke to let the Konoha shinobi manage the other Akatsuki to make his revenge a little easier. Although Sasuke is hesitant, the trio disappears in a puff of smoke.
