Disclaimer – I don't own Naruto

Author's Note: Hi readers. Sorry I took so long to upload this chapter. My computer got a virus and it took a while to clear. This time I made my story in a different format so that it would be easier to read. Enjoy and please review.

Tsunade stared into the face of despair. They faced an opponent who had never been defeated and this thing was the reason why.

'Ibuse do it now!' Hanzo instructed. The salamander opened its huge mouth and began pumping out a huge purple fog.

'Gamabunta, Manda Katsuyu, escape!' Tsunade screamed.

Her screams were unheard in the resulting chaos but it wasn't needed. All of them jumped away from the approaching fog except for one: Orochimaru.

'What are you doing you fool?' Jiraiya shouted. 'You'll just get caught in it!'

However, Orochimaru stood there and made a sequence of hand signs.

'Wind Release: Great Breakthrough!' he shouted. A large gust of wind blasted at the fog, but instead of being blown backwards, the fog seemed to come faster.

Orochimaru was caught in it before any of them could do anything. Manda's tail lashed out at Hanzo.

'Little worm,' he hissed as Hanzo bound nimbly out of the way. 'Only I can kill that one.'

'Acid Slime!' Katsuyu surged towards Hanzo and blew out a giant wave of acid. Hanzo dodged it and when the acid hit the ground, it dissolved, leaving large craters in it.

Gamabunta and Jiraiya attacked the salamander while Tsunade carried Orochimaru's limp body out of the battlefield as soon as the poison fog cleared.

She peeled away his shirt ignoring her embarrassment. She tied up her hair and rolled up her sleeves. She made several cuts into his body with her scalpel to try and get out as much of the poison as possible.

One look told her that this poison was fast-acting. His cells were poisoned badly, paralysed by the poison. First she needed to...

'Tsunade watch out!' Jiraiya's warning came just in time as Tsunade turned in time to grab the handle of Hanzo's thrown kusarigama. The weighted end was flung at her and one of her punches destroyed it.

She pulled on the chain with her monstrous strength which brought Hanzo along with it. She punched Hanzo when he came into range but he burst into white smoke. A shadow clone!

'Acid Slime!' Katsuyu spat out another acid blast but this time Hanzo was prepared. He dodged the blast and jumped straight onto Katsuyu.

'Summoning: Release!' He slammed his hand straight onto Katsuyu and she disappeared in a cloud of smoke.

Manda surged forward and opened his mouth to swallow Hanzo but Ibuse chose to break away from Jiraiya and Gamabunta at that exact moment to blast the poison fog at Manda. He closed his mouth quickly but when the smoke cleared he was lying on the ground.

She immediately got suspicious. How could Manda possibly have inhaled any poison? She was sure his body had gone still to hold his breath before the poison hit him.

'Earth Style: Swamp of the Underworld!' Jiraiya's jutsu made Ibuse start sinking but before Hanzo could do anything, Jiraiya attacked.

'Ninja Art: Toad Mouth Bind!' A large fleshy wall enclosed Hanzo, the stomach of a giant, fire-breathing toad; or so Jiraiya told her.

'How is he? Jiraiya asked, rushing over. She didn't bother answering, she had to concentrate.

Using her chakra, she formed a large globe of water in her hand and took out a vial from her remaining medical tools. Since she was using water, which wasn't as thick as healing fluid, she could only purge the poison from his veins.

Tsunade began the Delicate Illness Extraction Technique. While she operated, in her head she was going through all the information she had acquired so far. She finally understood how the poison had affected both Manda and Orochimaru. It had entered their bodies transdermally: injected into the body without breaking the skin.

She had also figured something else out. This poison worked by infiltrating the body and paralysing every cell which meant that if even a trace entered a vital organ it would stop functioning altogether.

So why? Why didn't he use it all the time and just kill them if he had such a powerful poison at his disposal? The answer was simple. He couldn't. She had been counting and now she knew that the poison took about five minutes to prepare before it could be exhaled.

Tsunade pulled the last of the poison in Orochimaru's bloodstream out and put a few samples in some vials. She didn't have any herbs so she was going to have to get rid of the rest of the poison with something else.

Suddenly, Ibuse disappeared in a puff of smoke and his tail was left behind and the Toad Mouth Bind opened up to reveal nothing inside.

'Digested by the acid,' Jiraiya said smugly. 'The great Hanzo brought down by the even greater Jiraiya!' He was grinning like a child but Tsunade ignored him.

Without any warning she threw a punch at him. He dodged, alarmed by her reaction, but her target wasn't him. She hit the ground with her punch and added in a little chakra to turn her crater-making punch into something that cracked open the battle field.

'What the hell are you doing Tsunade?' Jiraiya shouted. He glanced back at the field shattered by her punch and gulped. If he had been hit by that he was sure half his body would have been blown away.

Looking closer, he saw a vague shape emerging from the rubble and his eyes widened. It was Hanzo!

'Impressive, finding me while I was hiding girl,' he said mockingly. 'How did you know?'

'You left behind Ibuse's tail when you teleported,' she replied. 'There was a teleportation formula on it so you could bring yourself back after Ibuse reverse-summoned you, but it took you a while to knead the chakra which is why you were in the toad for so long.'

Without any warning she whirled around and exhaled a purple fog onto Orochimaru and Manda. 'Ninja Art: Poison Mist!'

Both Jiraiya and Hanzo stood there shocked by what Tsunade had just done. When the mist cleared, Orochimaru and Manda appeared to have stopped breathing.

'Tsunade...' Jiraiya whispered. 'What have you done?'

Suddenly, Orochimaru and Manda began to shudder violently and began to wake up.

They got up slowly and Gamabunta snorted when Manda fell over on his first attempt to get up.

Jiraiya and Tsunade helped Orochimaru to get up and they stood together, but there was one person who needed to join them.

Tsunade bit their thumb and made the hand signs. 'Kuchiyose no Jutsu (Summoning Jutsu)!'

In a puff of smoke Katsuyu reappeared and they were finally ready.

Jiraiya, Tsunade and Orochimaru stood with their summons for their final stand against Hanzo.

Authors Note: This one took me a while to write and I think the next one will be the last chapter but I'm not sure yet. I'm going to be studying for the next few weeks so the next chapter will take a while but please review. Thanks a lot!
