Goku is sent to the Narutoverse by Bulma's dimension machine to explore and see what's it like in the other universes after agreeing to do so.

"Awww Man I should've brought some food before going" Goku groaned as he began to fly. But as he was flying he saw 5 people battling one person with very long black hair. His landing intorrupted their battle as they all looked at the new stranger.

"I don't know who you are stranger but I suggest you leave NOW !" Tsunade yelled.

"What ! why ?" Much to Goku's confusion "Listen Madara is a very dangerous man and you better get out of here or else he'll kill you" She yelled angrily

Goku's confusion turns into seriousness as he looked at the man called Madara who looked back at him with an emotionless face. Goku then slowly began walking towards Madara very calmly. the Kages were in shock did this man not know who Madara is, did he not know how powerful he is ? Goku soon stood inches away from Madara.

"You are quite the bold one coming to challenging me." Madara said.

"Why were you fighting them is there a reason ?" Goku asked with a serious look in his face

"Not much just mearly dancing" He said

Goku then looked back at the Kages who were shocked and looked back at Madara again.

"Let's fight somewhere else away from them" Goku said to the Uchiha

"I highly doubt you're in any position to be talking to me like that" Madara said

But at this point Goku caught Madara off guard by grabbing him by the throat and flying miles away from the Kage who are now even more shocked

"W-What just happened" Was all Tsunade could say

Meanwhile

Goku finally lands somewhere away from the Kage in a deserted are with no humans,animals nor plants and let's go of Madara who back flips away from Goku.

"What just happened ? I didn't even see him move with my Sharingan !" Madara thought shocked

"Now then let's settle this" Goku said getting ready to fight

"Hmmm...it seems that you'll be a challenge for me after all and I though you wouldn't even be able to harm me" Madara said

Both Goku and Madara began Fighting each other at an inhuman level of speed. Madara then throw a kunai at Goku which he catches but he failed to notice the exploding tag attached to it.

"Huh ?" Was all Goku said before it exploded in a massive explosion.

"Hmh...Was that all ? it seems I overestimated you" Madara said thinking it was over but suddenly Goku appeared behind him kicking him in the back and sending the Uchiha crashing in the gound.

"It seems you underestimated me rather than overestimated" Goku said as the Uchiha got up in shock as he looked back at the saiyan who was unscratched

"Was that a shadow clone ? If so how was he able to do it without me even seeing him with my sharingan" Madara thought again

Once again Madara and Goku began fighting each other extremely fast but it soon became clear that Goku had the upper hand as punches Madara in the chest sending him a few feet away but Madara did not lose his footing "Fire Style! Majestic Destroyer Flame!" Madara then unleashed a huge amount of flame on his opponent but Goku simple released a huge amount of air putting the fire out and shocking the Uchiha again "He was able to put out my fire With a simple air release ?" Madara thought. Madara then used his Sharingan and looked directly at the Saiyan's face to put him under Genjutsu but Goku simply disappeared and reappeared next to Madara kicking him directly in the face sending him crashing in a mountain.

"His immune to Genjutsu ? Who is this man and why can't I sense his chakra ?" Madara thought as came out of the mountain and looked in the air to see Goku floating "He can fly as well ? This is going to be far more difficult than I thought" Madara thought.

"I suggest you give up now" Goku said glaring at him

"Quite the heroic speech but I'm afraid that that's getting old" He said as he looked in the saiyan's body but to his surprise he saw no chakra flow as if his body had no chakra at all.

"Amaterasu" Madara then unleashed a massive black flames directly at the heroic saiyan and was swallowd in the flames but after the flams died down it was revealed that Goku was in an Energy Shield. Goku then dropped his shield and appeared right in front of Madara. he grabbed the evil Uchiha then threw him on the ground but before Madara even touch the ground Goku appeared kicking him sky high then appearing from above and elbowing him in the back causing Madara to crash in the ground.

"Give up yet ?" Goku asked as he floated near the Madara

"Oh far from it." Madara said as he got up and suddenly a giant blue skeleton-like being surrounded him. Goku the looked extremely surprised as Madara was now in a gigantic humanoid being and in unsheated it enormous sword slicing some mountains.

"this is my Perfect Susanoo it's power is comperible to that of a Tailed Beast" Madara said while he was inside his Susanoo. But the saiyan however was not that impressed.

"Is that all ?"Goku asked

"What ?" Madara asked again in his Susanoo

"I didn't wanna use this unless I'm left with no choice but you just don't seem to want to understand what true power is " Goku then floated where Madara was at he same high but meters away.

Goku then began to scream and a golden aura was surrounded him,Goku's hair becomes spiky and golden along with his eye brows and his eyes become blue. Madara now was staring at the super saiyan but goku was not finished yet, he continued to power up causing his hair to become even more spiky, his eyes were now more green and his body was sherged with electricity still goku's power continued to grow.

Meanwhile

the Kages were going where Goku took Madara but stopped when they saw the sky turn black and stormy and massive earthquacke could be felt.

"What is that" Trunade asked

"It's coming from where that stranger took Madara" Gaara said

"We need to hurry !" Tsunade said as she and the Kages continued to move to the direction where the battle is.

Back in the Battle

After Goku finally finished his transformation His eye brows were gone,his pupels returned but his hair now reached his waste. He glared at Madara who was still shocked by this.

"I still can't sense his chakra what is going on here ?" Madara though in shock

"Now the let me show you what I can do" Goku now in a much deeper voice said as he put his arms on his Rite side " KA-ME" at this point a blue glowing light can be seen in the saiyan's hands "HA-ME" the light begins to glow and then "HAAAAAAA !" Goku fires a powerful energy beam right at the Susanoo.

"NOOOO" Madara yelled as he tried to attack but was swallowed by Goku's Kamehameha wave and annhiolated. Goku then turned back to normal and lands on the ground softly just in time the Kages arrive

"W-What happened ?" asked Tsunade in complete shock

"Don't worry I took care of that Madara guy" Goku said with a cheerful tone

"What ! How !" Onoki asked

"Well you see-" Goku never got to finish as groan can be heard. When the kages and Goku look they were surprised to see Madara getting up in the creter where his Susanoo stood.

"Never...never have I been defeated like this...not even by Hashirama"He said

"Your alive...but I shot you at point blank" Goku said surprised

"He's has become an Edo meaning he's immortal the only way to defeat him is to seal him away" Tsunade told the saiyan

"Is that all ? That shouldn't be a problem" Was all the saiyan said as he immidietly grabbed the Uchiha and flew in space then he let go of Madara to float

"I...Can't breath" Madara said as he continued to float in space

Goku then teleports back on the ground where the Kages are

"What did you do ?" asked Tsunade

"I just let him go in space, he might be immortal but in space he can't breath, he's basically in an endless torture and I don't think he'll be coming back any time soon" Goku said

the Kages were in complete shock this man defeated Madara and it didn't even seem like he tried.

"Sorry I forgot to introduce myself I'm Goku" Goku smiled.

well that's all for this one hope you enjoyed
