A Plea from a Friend

is episode 133 of the original Naruto anime.

Synopsis
A huge explosion comes from Naruto. Sasuke is dumbstruck and wonders what caused this sudden display of power. He also wonders about the red chakra that healed all of Naruto's wounds coming from Naruto before. Sasuke then asks what Naruto is and Naruto says he that is Sasuke's friend and he will not let him go to Orochimaru. Naruto also says that he would break Sasuke's arms and legs to stop him from going.

Naruto then punches the air and water goes flying towards Sasuke knocking him back, and then Naruto charges him. Naruto punches Sasuke with a hard fist then Naruto starts to punch Sasuke sending him up into the air. Sasuke lands on the water but Naruto is appears above and zooms through Sasuke sending him shooting like a missile into the water. As a giant hole where Sasuke was standing bubbles up, Naruto starts to howl like the demon fox inside him.

Sasuke emerges from the water next to a wall. Naruto uses his new-found speed to charge Sasuke and kick him sending Sasuke flipping back in the water. Sasuke recovers from the fall but Naruto is right there and starts to attack him with hard strikes at Sasuke's stomach, head and torso with such blinding force that Sasuke becomes disoriented and stumbles through the water.

Naruto back flips onto a wall and then into the air. Sasuke quickly performs some seals and uses Fire Release: Great Fireball Technique and a massive ball of fire comes from Sasuke's mouth, but due to Naruto's strength from the fox inside him he is able to block the ball of flame putting it out causing a massive shockwave of water from the spot where Sasuke and Naruto are. The water continually vibrates and eventually creates a whirlpool of destruction that sends Sasuke flying through the air.

With Sasuke still on his back, Naruto comes down and shoves to kick into Sasuke's stomach sending Sasuke back down into the dark water. Under the water Naruto starts to strike Sasuke with punches. Sasuke is unable to recover for a few seconds, and is even sinking, when he swims back up to the surface where Naruto uppercuts him, forcing him up into the air.

Then Naruto kicks Sasuke in the head and grabs Sasuke's legs and throws him into the rock wall. Sasuke gruesomely slams into the rock wall. Naruto grabs Sasuke by his shirt and yells at him, asking him if he has come to senses yet. Sasuke regains consciousness, and immediately yells at Naruto to shut up, telling Naruto that he could not possibly understand what it feels like to lose his whole family, exposing the fact that Naruto did not have siblings or parents in the first place. Sasuke again states that Naruto was alone from the start, telling him he does not understand. He also says that families suffer because on their bonds and that Naruto do not know how it feels to lose them. Sasuke grabs Naruto's arms and jumps off the rock edge they were sitting on, and Naruto's smoke bombs fall out of his pouch and explode, setting off a layer of smog that covers the two as they fall.

Both of the them hop onto a log and get into a fighting stance. As the smoke clears from the bombs Naruto states that it is true that he does not know anything about parents or siblings, but explains during a flashback that he thinks of Iruka as a father, and he wonders if that is what it's like to have one. Another flashback shows a montage of scenes where Naruto and Sasuke are seen training together or joking around, and Naruto is heard telling Sasuke that he considers their friendship to be similar to having a brother.

Sasuke asks why Naruto would go so far for him. Naruto says that it was one of the first bonds he had with somebody. Naruto states that he will stop Sasuke no matter what. Sasuke is seen shocked, followed by a flashback of Naruto and Sasuke by the pier, a curious Naruto seen looking on at a lonely Sasuke. Eventually Sasuke realizes that someone is watching him, and turns around, only to see Naruto walking away with a smile on his face. Sasuke eventually smiles back, and returns to what he was doing. Naruto is then seen looking fondly at Sasuke, convinced that Sasuke is on the verge of returning to Konoha. Sasuke takes out his headband and puts it around his forehead and says that it is too late for him to go back. The log Sasuke is standing on snaps and Sasuke stands on the water and grabs a piece of wood and throws it at Naruto's log. The piece of wood catches on like a splinter, and Naruto's log quickly collapses, and Naruto adopts a fighting stance, ready to continue the battle.

A third tomoe appears on Sasuke's Sharingan, gaining the full power of the sharingan, and he calls for Naruto to come, that he will break the bonds of their friendship. Naruto comments on why Sasuke even bothered to wear his forehead protector, and Sasuke explains that because Naruto knows the pain of others, he considers him an equal. Sasuke says that Naruto won't even be able to put a scratch on his forehead and that fact will never change.

Naruto says that whatever he says does not matter to Sasuke. Naruto charges Sasuke with incredible speed but, harnessing the full power of the sharingan, he is able to overthrow Naruto's attack, and Sasuke sees Naruto's every move now because of his new Sharingan and blocks Naruto's punch, flipping him over his head, and Naruto lands and does a spinning kick to Sasuke's head, but Sasuke avoids the kick. Naruto tries to deliver a few strikes but Sasuke delivers his own fist to Naruto's jaw causing Naruto to roll over and try a strike again, but Sasuke jumps onto the rock wall and gets into a fighting stance again. Naruto comments that Sasuke's moves are much different from before.

Naruto follows Sasuke up and and they charge at each other with their fists. Sasuke, with the advantage of his full sharingan, is able to predict Naruto's movements, and he says to himself that he can conserve chakra this way, rather than suffering the massive chakra drainage during the Curse Seal Activation. Naruto strikes his fist too early, and as Sasuke sidesteps out of the way he delivers a shocking blow to Naruto's face, knocking him into the water. We then see Kakashi running to catch up to Sasuke and Naruto. Naruto appears out of the water with four shadow clones which Sasuke destroys. Then, a succession of shadow clones are seen coming down from the air and Sasuke sees their movements, carefully dodging and eliminating every single one. Sasuke stands on the water, waiting for shadow clones to come, until he is convinced that he has defeated all of them. Sasuke relaxes, but Naruto grabs Sasuke legs from under the water and uses a chain of shadow clones to throw Sasuke into a rock wall again. Sasuke gains consciousness, and sees Naruto at the edge. Sasuke, in an act of panic, uses a fireball to destroy all of the shadow clones.

As all of the shadow clones drop into the water the fox inside Naruto opens his eye. Sasuke grabs Naruto and pile drives him into the ground below. Naruto's body is sticking out of the ground in an awkward position, and eventaully he tips over into the water and floats there. Inside Naruto the demon fox says that he is too weak. The fox starts to laugh and says that Naruto should be thankful to him. He also says that had he not been sealed by the Fourth Hokage, Naruto would be dead by now. Naruto lies in the water on his back and red chakra starts to cover his body. Sasuke eventually steps out of the ditch and drops to the water below, a look of terror on his face as he witnesses the red chakra pouring out of Naruto. Naruto, assisted by the demon fox chakra, slowly gets up and punches Sasuke right in the face, sending him spinning into the water. Naruto at this point seems to regain his consciousness, as he glares menacingly at Sasuke as he is on the water, holding his face.

Naruto grows a tail made of chakra and moves like a fox, attacking Sasuke, making him get up on to a log. Sasuke says that he can't follow Naruto's movements like before. Sasuke starts to shoot balls of flame at Naruto but Naruto avoids them. Then Sasuke uses Fire Release: Great Fireball Technique, but the red chakra protects him, and he continues to advance towards Sasuke. Sasuke lands in the water and a huge red hand grabs Sasuke pushing him into the rock wall.

Sasuke is forced to use his cursed seal but the hand still grabs Sasuke and Naruto punches Sasuke in the face, causing him to go back into the wall. Sasuke laughs and says he is going to use the second level of his curse seal. As the curse seals attach together Sasuke's hair grows longer and his nails extend and his skin becomes a light brown color and a huge black mark appears above Sasuke's nose. Sasuke says that he is more special than Naruto.
