Charka, everyone has it, even if most never learn to use it. To be without Charka is to be without life... So then, what does it say when one has utter mastery of their Charka?
----
Looking down at the boy, the hired shinobi scoffs. Sure, the grey-haired boy has some talent for the ninja way, and if he was anyone else he'd probably have an issue with killing such a promising Leaf nin.
Today, though, he'll finally be free from running. The Land of Iron thought they were clever hiding their involvement, but the fact this brat is the bastard of a Daimyo? Please, either he gets safety or he'll completely ruin that worthless man's reputation.
His eyes suddenly narrowing in suspicion as the boy chuckles weakly, he hurls a shuriken at the boy's throat as his senses go on high alert to check for Genjutsu-
Yet the shuriken ricochets off the boy, and nothing seems to change as he performs the Genjutsu breaker. Hmm, maybe he's incredibly talented with Genjutsu for his age?
No, can't be, you trained specifically to counter Sharingans- the extinction of the Uchiha was far too suspicious, probably farmed all the eyes to implant in their elites or something.
If not Genjutsu, then- Flickering away out of sight, you'll need time to break through whatever defense technique he's using. Maybe the Iron Daimyo has a secret kekkai genkai? Might explain why they care so much when the boy seemed to have no interest in usurpation.
Raising up two Earth Clones to keep the boy distracted, you better watch him as you prepare the technique- wait why is the air turning blue? Is he seriously flaring up his Charka? Idiot, must think some 'charka cloak' is cool.
Hold on... is it getting thicker? Hmm, interesting, shame he lacks intelligence to match that control. Sending forth your clones, you're not surprised when the boy tries- wait he actually got out of range.
That isn't right, you had him dead to rights before that nonsense chuckling. He even still looks injured... when did his hair and skin turned blue? That, that is really weird. Must be a last-ditch maneuver, his Charka can't last long like that.
Still, maybe you'll attempt it afterwards, wrapping yourself in Charka has applications. Odd though, surely Leaf doesn't teach techniques like that? No way his sensei would of taught him such a wastefully limited technique.
You can feel it already, just need your Clones to get him into position and... "Earth Release: Bedrock Coffin!" That's that boy, maybe in the next life your home country won't put a hit on you.
Wait, did something just blur? There was definitely a swishing noise. Examining the area and remaining on guard, your eyes dart without your thinking as an explosion rings-
W-what? What!? B-blades of pure Charka, extending from... how is that boy still alive!? He shouldn't know any real Jutsu, so how!? No, remain calm, this just lends credence to the 'secret kekkai genkai' theory.
Right, even though the boy has some weird bloodline letting him shape his Charka into sturdy constructs, he's still just a boy- and you got real control & reserves compared to him.
Calling up an Earth Wall to spook him, you send out one of your Clones to attack him as he approaches- is he standing on thin air? Does he seriously know elemental jutsu!?
… No. His Charka aura is flaring... huh, hahaha, he learned how to float with pure Charka? Tsk, really is a shame you have to kill him. No matter, flight can't be cheap for him and he doesn't know where you are.
Maybe he'll run? No way he can get to a settlement before burning out, and surely he still remembers you're the better tracker. All he's doing is delaying the inevit-
Wait what where did he go!? Hearing an explosion of shattering stone, it seems... huh, he shattered your Clone in one punch. How did he move so fast? Frankly, what about that power? He wasn't that strong when you were fighting...
Hold on, why does his Charka still seem to be going strong? He just forced himself to move and hit at impossible speeds, turning your clone into a shuriken launcher.
Is he...? No, no, he can't possibly be a jinchuriki. Yet, why is this boy's Charka not degrading fast enough? It makes no sense if this is a kekkai genkai, either his father should of become some Samurai Kage or his mother prioritized as the Daimyo's wife.
Maybe, Konoha has some freak training regimen going on...? No no no, none of this makes sense! Whatever, Coffin! Tsk, now you see it... Don't think you'll escape this time boy!
Coffin, Coffin, Coffin! Huff, huff... oh? Did you finally do it? Hmm, hope there's something reasonably intact, need to prove the job's done. Sending forth your remaining clone and letting it merge into the Coffins...
!! The multi-layer Coffin shattering and scattering as a sphere of Charka bursts forth, you're forced to quickly Flicker away from the shrapnel. Seriously, there was nothing about this! Did those Iron bastards set you up? No, they shouldn't care about you at all, so...
Fixating on the boy, you can't help snarling. Maybe, this is Kisame's brat? Hmm, mug's too ugly for some high class concubine... Just what the hell spawned this monstrous child!?
Perhaps... you should run. Sickening, but... he's way too much Charka for a kid. Already can feel yourself getting low after all those Bedrock Coffins... Wait, wait the air is turning blue.
Oh no, you need to go now! "Found you!" Wait what- feeling bark shatter against your back, you groan as you look around. Oh, oh great, your left arm and leg are clearly broken...
"Gah!" H-hurts trying to get up... Eyes darting wildly for the boy, you can barely see anything through this blue Charka fog of his. Hold on, it is shrinking? Finally, finally he's-
Right in front of you, skin and hair the blue of Charka. J-just... "How? Y-you're just a boy! Ka-hack hack-" Lovely, you can taste your own blood now. How awful, you can just see it now- being mocked by a higher power for being offed by a child.
He seems to regard you for a few seconds... shame, really should of made a habit of carrying explosive tags. Could of at least took him with you... "How? I'm sorry sir, but I don't reveal my secret techniques to dead men."
Pfft, just figures he'd- C-c-crack boom!

Charka, in capable hands it could practically do anything- command the elements, resurrect the dead, imprison the mind in delusions... Yet at its base it is energy, a substance to be manipulated and controlled.
So why bother with fancy tricks, when you could just wrap yourself in it and command it as you please? Blades of pure Charka, keeping one aloft, hurling that mass so fast and so hard any normal person would explode... That is power, to force the energy of life to obey your simplest commands.
