Hello everyone! Welcome to my first Naruto Undertale crossover. Now if you got any ideas on how to make this better or I did something wrong then please let me know! Also, a big thanks to Alphadash117 for the idea. He basically gives me the ideas and I write em out. Anyway hope you enjoy!

Edit: I updated the story a bit so there are less mistakes. Also since I got a few complaints about this story im going to put up a warning...This Naruto is nerfed. The reason for that is because...well...what type of character development will come from him just being able just kick there asses in seconds. If Frisk, a untrained child could dodge those attacks, then Naruto can as well. Sure she has Reset, but she would still need the body and speed to dodge.

Pain...Pain is all Naruto could feel. His face sore and covered with bruises. His stomach and chest ache from all the punishment it took from his former best friend. Naruto isn't even sure if they were ever friends. To add insult to injury, he fell hundreds of feet.

His once orange jacket is now nothing more than rags covered orange. His right sleeve has been torn off from his elbow, and his left sleeve ends right above his wrist. His jacket is open revealing his mesh shirt also exposing his cuts and bruises. His pants are looking a little better, but you can still see some tears and rips.

Naruto lifts his head up to look around, trying to spot anything that might help him in finding out where he is currently located. All he can see is darkness and a bed full of golden flowers. "W-Why...couldn't I have landed on that" grumbled out Naruto as he tried to get up. Even that was a challenge.

It took a few tried, but Naruto finally managed to get up off the ground. As he did though, he realized something…..He was short….A lot shorter. "Eh?...Eh!?...WHAT THE HELL DATTEBAYO!" Stuttered Naruto as he looked over himself. He was about four-feet-nine-inches, and he had a lot more baby fat then he should have.

'Kurama! Ya know whats going on?' Naruto asked the beast inside him, but he never got a reply. 'Kurama? Ya there buddy?' still no reply. Getting tired of waiting, he decided to talk face to face. Naruto closed his eyes and found himself in his mind scape.

As Naruto enters his mind scape, he expected to see his big furry friend. What he saw was Kurama, the mighty kyuubi no Yoko looking horrible as if he had just gotten a very bad sickness. His once bright orange fur looked more dull the it should be. It also looked like he was having a hard time breathing.

"KURAMA!" yelled Naruto with worry. He quickly made his way over to his friend trying to see whats wrong. Again, he got no reasons. Naruto could tell that the Kyuubi was still strong however, he could feel a chunk of his power was taken away. This eased Naruto's worries a bit, but he was worried nonetheless. With a sigh Naruto left his mind scape.

As Naruto opened his eyes he finally realized something. His chakra felt….off. It felt like it was all over the place. Realization dawned on the blond shinobi. Naruto looked up and saw a hole leading to the surface, so he quickly tried to run up the there by putting chakra to his feet. Only to fall before he even made it a step up.

'M-My chakra….Did everything get turned back?' Naruto can take becoming a eleven-year old again. Even though it's a bit hard to take in, he has seen weirder, but having all his power being turned back again? All the hard work the blond has done was for nothing.

Not only is his friend down for the count, but he was also stripped of his power. At least for now. If he has the same amount of power as he did when he was 11, then he could get it back when he either gets older or trains harder. Still though, it sucks having everything that he has worked for gone. It's like having to spend a lot of money when your saving up for something. 'No use crying over it. Found that out a long time ago…' With a small grin on his face, Naruto made his way forward towards the darkness…..At least that was the plan until he saw a flower with a smile of its face.

In front of Naruto strode a flower with golden petals, kind of like the ones in the flower bed. The next thing that happened shocked Naruto…..It spoke. "HI! I'm Flowey! Flowey the flower. I couldn't help bu-" before Flowey could finish, Naruto burst out laughing. "HAHAH! What kinda stupid name is that!" Let it be known….Most of the time the blond knuckle head says stuff without thinking. This of course did not make Flowey happy….In fact it just pissed it off. It's still kept up a smile though, only a lot more forced than it was before.

When this happened Naruto noticed two things. One, he noticed that smile that Flowey gave him. Under it was something dark and …..He could still sense negative emotion. He quickly stopped laughing and jumped out of the way in order to dodge one of Flowey's attacks.

Right after he dodged, everything became black…..even him and Flowey. "You seemed confused. Let me explain" said Flowey, losing his kind smile. Now he is sporting a creepy grin which if you were to ask Naruto…..it kinda fit him in s strange way." See that heart? That is your soul. The very culmination of your being! Your soul can start, but can grow strong if you get a lot of LV" said Flowey with killer intent leaking out of him.

"What is LV?" asked Naruto with curiosity and a bit of nervousness. Something told him he was not going to like what he will be told. " heh..heh...HEHEHEH! It stands for level of violence...from what I can see, you seem to have quite a bit." Naruto looked down and saw numbers. XP had a 0, but LV had over a hundred. In this world...its kill or be killed."

When Flowey looked at the blond, it expected a reaction of fear or worry. Instead it got a deadpan look from Naruto. "...Your a small, little flower who talks about kill or be killed….If anything your cute."

This got a reaction out of Flowey, and not a happy one. "Cute?...Cute...CUTE?! ILL KILL YOU!'' Flowey started firing flower pellets at Naruto make the former teen dodge. "OI! ALL I DID WAS CALL YOU CUTE!" Naruto winced when he stopped moving. He completely forgot that he was injured.

Flowey just ignored him and kept firing at him. One hit Naruto square in the face. "OW! How the hell does that hurt as much as a senbon!?" The attacks did not stop though. They kept firing with some hitting him.

This reminded Naruto of the wave mission when Haku fired senbon at him. It felt almost exactly like that. This time though, Naruto is going to fight back. As the little projectiles kept firing at him he dashed closer to Flowey with his fist pulled back. That is when he noticed something. First of all he was still hurt, second he did not keep his old speed and third...he had not gotten used to his younger height.

Naruto was then hit with another projectile, but this time on his bad leg. Soon, pellets surrounded Naruto closing of all his escape routes. " I told you...Its kill or be killed in this world! HAHAHAH!" Right when he was about to finish of Naruto, a fire ball hit Flowey.
