Underneath the flying city of Atlas, deep inside in a secure cave where experiments were being performed and conducted, from Grimm to human beings or even Faunus...

But inside a massive Vault inside was someone chained to two massive pillars of unknown origins as the figure with his arms lifted up, and on his knees, with his face facing the ground, his dark brown hair covering his white ghostly eyes, as the chins glowed gold, with scripture of Greek, Roman, Egyptian, Arabic, Ancient Sanusan (Canadian French). Where the figure is facing was several Atlas scientists and doctors, and physicists who experimented on his body, from cutting him, torturing him with [Redacted] and injecting him with [Redacted] dust... to being beaten by Atlas guards of course the figure is... or well was Jaune Arc....

Before Jaune was betrayed and sent to prison for the Worst offenders on the planet in Atlas. He was like anyone else at a young age, to become a hero, like his grandfather (Notch)  told him about stories of heroes doing great things in their lifetime lol  King Arthur, Jeanne D'Arc (both are ancestors of the Arc Clans (including Salem).) so he like any child he wanted to train to become stronger. But his parents didn't want him to become a hero for unspecified reasons, but grandpa was against Jaune parents ideas and trained him to the best of his abilities, away from Jaune's family, who his parents were training his sisters and not him.... But when Jaune was old enough he left beacon with the support of his grandfather.... And the rest is history his transcripts (the fake one) it's released to everyone, his teammates and friends turn on him, the teachers and the headmaster tried to help him as the best they could, the council members get news of this and in the trial needs badly for the crimes and his sentenced to the worst prison with little to no escaping of it, and his "friends" cheered seeing him go and gone with like a little traitor he was....

(A/n: I'm not as good with backstory stuff with Betrayed Arc stories like most Other Authors out there who are probably reading this..)

(Now back with story)

In the prison dead under the ground below the flying city of Atlas, Jaune no Herobrine watched or was listening to whatever the Atlas scumbags were talking about... something that would trigger him.

Atlas Scientist: I heard that K-423 was going to doing more experimenting being done.

Atlas S. 2: like what the other test subjects who are [Redacted] changed into more hostile [Redacted] subjects who could easily kill anything in its path, just like the higher ups wanted a Bio- Weapon design for combat.

Atlas Scientists: Sure something like that.

Suddenly a rumble and chains straightened and the pillars cracked as Herobrine appeared trying to reach the two with brightly White Glowing Eyes as the rumbling started again this time stronger as parts of the metal bars holding the stone roof up snapped and some metal beams fell nearly killing one one of the Atlas engineers who was working on the generators, as the generator was smashed sparks came flying out and suddenly the lights went out.

Sounds of chains snapping and then Bloody screaming was heard even through the Vault door which was sealed off. The guards who were guarding them were frightened by the ungodly screams of Death inside, only for the sound to stop.... And then BANG! The meat vault had a huge bump like a fist just violently punched it, then again BANG! And Again, & again the fist sized bumps of the vault. Then the Vault door flew off its hinges and the gears holding it crushing the guards underneath it.

Then came out herobrine his entire body covered in lighting dancing around his body and around his arms as he walked out with his feet and arms covered in blood... as several footsteps echoed through the halls as several hundred soldiers came in and aimed their weapons at herobrine who looked at them with a blank expression.

They opened fire at herobrine who wasn't even taking any damage from the dust rounds hitting his body, so he slowly started walking slowly at them, as some of the soldiers noticed this and began backing up, but one didn't notice it yet until he stopped and stared in shock and spit out blood and dropped his gun as Herobrine had his chest completely through and out his back holding his heart still beating before being forcibly pulled out ripping his heart out killing him instantly then crushed his beating heart letting it explode in blood and parts of organ flying everywhere....

The soldiers looked at their now dead comrade with a hole in his chest fell like a sack of potatoes,  two immediately took off running as the other soldiers fired at him as bloody screams echoed out before it when silent.

Herobrine looked around his surroundings before turning the opposite direction of where the soldiers were running towards, and towards to  section called labs.... Once there he ripped the doors off its hinges and walked in but not before throwing the steel doors at the scientists & guards killing them instantly with one go, and walked off with no emotion escaping him.

(A/n: Get it because he has a Diamond heart and a cold withered Soul stripped of all emotions and aura and semblance.)

Continuing walking he stopped when he noticed a strange Grimm creature with what appears with tendrils it noticed a unfortunate soldier who opened fire on it and ignored Herobrine, before running and jumping towards the soldiers who tried to fight it before it dug into him and began infecting him as he held on to stomach before his right arm grew three long bone like appendages like weapons as the person turned into a combat from and turned to face herobrine and before it could even attack a sickening *cruch* was heard and a *pop* before the creature fell dead its skull caved in violently. Herobrine looked at it before walking on killing anything and anyone in his way....
