Naruto's Anti-Toxin
I don't own any of the characters or symbiote
Summary: Naruto is the descendant of Eddie brock, from his dad's side, and due to the exposure of the Kyuubi and genetic processes the remaining few remaining symbiote cells (the anti-venom and toxin symbiote note the venom symbiote cells have been destroyed by the anti-venom cells) become active again.
To the story
Naruto had always been an odd child he held an odd kid he had an odd personality, always active always moving but always trying to help his oddness increased when one day at the age of 6 he was in the hospital he wondered away and ended up in the ER area where they had a kunoichi whom had just returned from to the village and she was suffering due to a seal on her shoulder.
Naruto had somehow gotten into the room with the kunoichi whom the doctors had given pain meds to and left as they were not versed in seals but that boy, according to the woman's hazy vision and senses, rid her of the seal with a single touch.
These outrages claim was confirmed by the head of the yamanaka who viewed her memories this baffled the council to the point that they called Naruto into the council to ask him if he was aware of his ability.
However the boy denied that he was aware of any such ability it was at this point that Danzo produced a wolf that was held in place by a paralysis seal as well as chains, unknown to everyone but Danzo the chains also had seals that would break the chains on command, Danzo then ordered Naruto to touch the wolf.
Naruto happily complained and to everyone's shock Naruto's entire limb seemed become paler almost entirely grey and not long after the wolf began growling and fighting its restraints.
Danzo sent a low pulse of his chakra causing the chains to snap allowing the wolf to lunge at Naruto.
Naruto gave a shout of fear and thrust his hand forward in an attempt to stop the wolf but everyone froze even the anbu that were at that point next to the wolf with their blades drawn to cut down the wolf.
Naruto's extended limb seemed to be covered in slime up to the wrist had turned completely grey after that the limb had become a deep crimson a little after the wrist all the way past the shoulder but the part that made everyone freeze was the fact that Naruto's hand had turned into a large blade and had pierced the wolf's chest.
The wolf fell to the floor dragging the bladed appendage with it Naruto opened his eyes slowly afraid that the wolf was still going to eat him but to his shock as the adrenalin died down in his veins Naruto became aware that the heartbeat he was feeling was not his own but in fact it belongs to the dying wolf the wolf began releasing pained whimpers as its blood began to pool around it.
Naruto as children often do began to cry he felt sad that he had hurt the wolf and he for the first time tried to force his apparent abilities to work.
The entire council remained frozen as the grey goo like fluid wrapped around the wolf and it remained like that for several seconds until it retraced Naruto's still grey and now claw like hand included, and revealed the wolf now without its wound but now the wolf seemed calm and began to move towards Naruto again and the anbu put their blades to the wolf's throat but the wolf gave the two anbu a sharp look before going under the blades.
Once the wolf was close it laid down at Naruto's feet and looked up at him as if waiting for a command it was at this point that a pink hair banshee gained her voice back, a true tragedy to the world indeed, and the first words from her mouth?
"THE DEMON HAS GAINED POWERS KILL IT QUICKLY!" the scream earned a smile from three of the less loyal anbu who immediately rushed in and attacked two stalled the anbu nearest to their target while the last rushed Naruto himself.
The anbu brought back his katana and put all his might into his swing but after his swing he noticed that Naruto was not dead and in fact the boy was not injured at all the anbu scowled and intended to swing again but he noticed that he couldn't feel the sword in his hand or his hand for that matter.
The anbu looked down at his limb and found that his sword and hand were gone after looking back at Naruto the anbu noticed that the wolf was no longer with Naruto and in a bit of shock began look for said wolf but as soon as he turned he was greeted by a long tongue and a mouth full of sharp teeth which clamped down on the man's head before he could scream the wolf landed and swallowed the matter now in its mouth leaving the fresh corpse to fall to the ground.
The wolf was now double in sized and its blackish grey coat was now a mix of grey on the paws with large serrated claws and head with a mouth full of sharp teeth while the chest was crimson the back of said chest was covered in white spines.
The wolf gave a deep growl and moved back to Naruto making the boy flinch as it wrapped itself around the boy eyeing the council as it did so.
The anbu that attacked during this time were cut down and after a moment to Hiruzen called the meeting to a close after ordering the banshee's incarceration before he asked Naruto to follow him to the hospital and after cautiously getting up from the wolf's embrace and followed as the wolf got up and followed reverting back to its original form as it tailed them.
