Rathy petty.

Matsuo was sitting in a forest on an island, looking at an egg "What do I do now? I have no idea how to hatch one of these things. You couldn't say that I have enough money to buy a hatching method either..."

He's had it for about a month, Matsuo used his chakra sense to sense the creature's yang "It has it at least, so it isn't a still born or anything. Good that yang is actually a thing in the rathalos too, chakra using rathalos would be amazing."

Matsuo even ended up making a huge nest for the, almost human sized, egg. He used a fire jutsu, hot hands, to see if he could use heat to nurture it. Then he thought of medical ninjutsu, which he had none of, except ones that could heal himself, like how he replaced his eyes a bunch.

The egg wobbled, and Perfected Matsuo's head turned instant "Haha! My perfection is great as always, seems I did nothing wrong in my expirements!"

Perfected Matsuo praised his perfected luck and made a snake sign "Fire style; breath of hestia."

The area around Perfected Matsuo increased by a few degrees celcius, Matsuo nodded to himself for a few seconds. Then sat down in a lotus position "If I'm correct, if I do this while eating metal I'll increase the speed of the 'metal dragon art'."

He took out some metal from his inventory and popped a cold one into his gullet, a few in fact.

About an hour later he opened up his eyes with a pretty metalic body "Haha! I upgraded it with the usage of mental energy to guide the metal into my body, and it worked like a charm!"

Perfected Matsuo looked at the egg with 'Yang vision', it seemed to be alive and well, JK. It only had a bit of yang left, Perfected Matsuo panicked and looked at the egg with his echo location.

What he saw made him cool down a bit, the egg had hatched, and the rathalos was sitting infront of Perfected Matsuo.

Perfected Matsuo paused for a few moments, pondering about the laws of matrimony "Boiiii! Imprinting for the winnnnnn! Money waste = zero!"

The rathalos jumped back at the sudden activity of what it thinks is it's mother, Perfected Matsuo didn't care though, he happily yoinked it and ran towards the continent with joy.

About a minute of rathalos panic, the two arrived at the county of fire.

With the rathalos in his arms, he paused, then shifted in some way and became blind Matsuo.

Perfected Matsuo blasted out a wave of chakra and felt where the most was concentrated in a few people "There." He pointed somewhere. After which he ran for the hills.

A few seconds later, with a skittish rathalos, Perfected Matsuo appears!

Punch 4 ninja! dead, no big suprise.

"Rathy! Eat, eat." Perfected Matsuo forced the rathalos onto the corpses, his face disdorted with evil "Eeeaaaat! Eat! Eat you dumb animal!"

Perfected Matsuo paused "Maybe I shouldn't treat it like a Xenomorph, which grows stronger with food consumption."

Matsuo waited for a bit for 'Rathy' to eat, for about a minute. After which he stored the bloodied bodies into his inventory, it seemed to be full "Good Rathy!" Perfected Matsuo petted the rathalos.

"We're gonna be the best of friends! Rathy and Perfected Matsuo, friends forever!" Perfected Matsuo paused "You're the side-kick."

-A month later-

"Isn't that the, oh so great, king of the clouds~?" Said someone to Perfected Matsuo.

Perfected Matsuo stretched out his arm and shot out strings of chakra, straight to the heart, he clenched his fist and said "Forbidden art; grasp heart."

The person fell down after spurting blood, Perfected Matsuo pointed at the limp body and said "Go get 'em Rathy!"

The rathalos jumped out and started to eat the man, Perfected Matsuo nodded to himself proudly. Like a father seeing his child sucessful, even a small tear fell from his eye.

-A year later-

Perfected Matsuo was flying on Rathy the rathalos, and was pondering to himself 'If I don't have a blood line... Do I not have the blood line of a human?'

[Affirmitive.]

"Oh boy! It sure is boring around here." Matsuo didn't realize it for a moment and made a one-liner, but then "Hail the lord all-mighty! Humanity is not my race, I am nothing! I am infinite!"

-Another year later-

"Breed my little money bag~ Breed!" Perfected Matsuo said to the two rathalos, after which he did some hand seals and shouted "Earth style; cave opening,? More like 'shut the fuck up and go to sleep'."

The cave closed completely, with the light source. After which a few days passed, Perfected Matsuo returned. He kicked the cave open, he let out the two rathalos out.

-A few months later-

Matsuo the perfect sat on a tree stump and was watching a few rathalos 'Cubs', he tehn pondered to the stars "How long have I been here?"

[Three years.]

"Wow, is it me, or am I forgetting my old life?" Perfected Matsuo looked through his memories, the asfalt streets and giant buildings being foggy and estranged "What even was my name back then?"

[Isaac.]

"Really?" He said to himself "I was thinking something cooler, like 'Tartarus' or something." Perfected Matsuo was dissapointed in his past un-perfect name.

Perfected Matsuo put on 'blind matsuo' mode, and rushed away towards konoha.

Standing infront of the gates of konoha, Matsuo the supreme perfect being put on a ring. A ring that dulled his chakra signature, he nodded and used his clouds to walk through the gates.

He walked around with a few sneaking thoughts, and a pride at remembering from something he didn't remember that Uselessness's rival's house used chakra sense to make sure no one of evil intentions appeared on the whole village.

He explored and found a little naruto house, he fell through the floor and fell back through the ceiling of the home.

He used some chakra to make a fake reality to the ninjas looking after the wicked fox of the east, he punched with chakra muffling onto the naruto face "EEEEYYYY! Welcome to the dream realm!" He yelled.

Naruto stumbled out of bed, but Matsuo continued "Did you know you're clifford the big red dog? Wait. No. It was a fox! It had 9 tails too! And you are are the crist king of the moon! Reincarnation of a god! I think."

"Man! The world is weird ain't it?" He said to the open air "Oh yeah! Your little fox pet is called kuruma! I think. You have a spectrum disorder! I think. You're an idiot! I think. No one will be your friend since they're afraid! I know! I reccomend beating them until they start working for you! Make a gang! Become the child beater!"

Perfected Matsuo took out a scroll "This is a scroll with a jutsu and the basics of jutsu, I reccomend learning it. Also, everyone else will see it as a vanure magazine, so... You deal with that... Anyways!"

Perfected Matsuo put it in a random drawer "It'll be here when you wake up, also..." He paused, pondering "I am the king of the clouds! The great-!"

Matsuo punched Naruto out cold, he slowly put him onto the floor next to the bed and did some chakra shit to make it seem to everyone he fell off his bed. Matsuo the great nodded to his perfect scheme, he fell through the floor and fell out of the ground.

After which he killed a few ninja with clouds and then ran away as if he saw the wicked witch of the east.

-Another year later-

Matsuo the great had a side quest.

[Side quest; Cause a massacre, the fatalis, the the fate of death that looms over all, none can escape it.]

But he didn't want to cause a massacre...

...

...

...

..... Yet.

The whole story would fall apart! But... Who said it had to be on earth, Perfected Matsuo looked at the night sky. Feeling determination in his heart, he lept to the sky and stept on the open air.

-Two days later-

Matsuo jumped out of the stratosphere and propelled himself out of the gravitational pull of the world, he had no clue how he was still alive. He did feel short of breath previously, but this was different "Wind style; Air for you, air for you, air for everybody!"

The chakra changed forms and took hold in his lungs, Matsuo breathed out normally, but without co2, but he could still breathe "What a wonder, jutsu really can do anything." He said, without saying anything, since, vacuum.

Perfected matsuo predicted where the moon would be in some time, made a platform, and jumped.

-A day later-

Matsuo was bored, really bored, but it's about to stop being boring! The moon was floating right into him!

He slowly landed on the moon, he made a step "One small step for man, one big step for all of mankind." Weirdly, this was heard, but it should still be a vacuum.

Matsuo 'looked' somewhere and instantly used a jutsu "Fire style; sea of flames." His mouth spewed out flames, and-

Wait... How did he know it was night, how did he know the position of the moon? This is a major plot hole! Let's see... Something about buying... Oh, system buying the position of the moon. How much did that cost? A few hundred ryo, good to know.. Good to know...

Matsuo had killed the moon men and started to triangulate their outpost with extreme chakra use.

Oh, wait. He's already there "Lightning style; Heaven's judgement!" clouds formed above the city, as the grew, and grew and grew, untill it blocked out the sun, becoming as large as the permanent storm on venus.

It started to crackle with thunder, which turned to a 'boom', then a 'crash', then a 1 mile across thunder bolt crashed into the city, killing thousands.

Wait... How did he use so much chakra?! Oh! He got back his infinite chakra exploit and had used thousands of chakra pools, and his enourmous amount of chakra usage had increased his chakra pools size... Isn't this too powerful?

Oh, it isn't, it takes more than an hour to do something like this. A lot more than an hour, but then how did he do it so quickly. I just blacked out from drinking heavily? Oh really, that's... Believeable.

Out from the ruined city, a black dragon flew out, as the chorus sung. Yes, the chorus, this one has a theme "Oh great Fatalis! The fate of human kind! Let's get out of the moon now!"
