Y/N violently smashed the crowbar against numerous Grimm, all of them cowering in fear. The Grimm began to run and hide in fear of the Y/N.

Salem
"What are you doing, kill him!"

Night stalkers, Beowulfs, Nevermores, Ursas, even dragons refused to follow her orders, the sight of their own kind literally committing cannibalism and self mutilation terrified them.

"What's wrong, your pets look scared!"

A dragon appeared, in which Y/N activated the semblance again, causing it to crash to the ground, and attack the rest of the Grimm.

"I've turned your own creations against you, they're no longer scared of you...But to me!".

Salem
"You should pay attention little boy!".

Mercury appeared, and attempt to kick Y/N away. But Y/N saw and smashed him on the head with the crowbar.

"What's the matter!!?"

I grabbed the Mercury by the leg, and smashed his legs with the crowbar. I soon began beating him to death.

Mercury began wailing and screaming in pain as Y/N beaten him to bear death. The crowbar cracked his skull, and ribcage.

"Now....Lose control!".

Mercury began laughing insanely, and stabbed himself in the stomach.

Mercury
"HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!!!!!!!!!!!!!!!!!!".

He tore into his stomach, and pulled his intestines right out. Salem watched in horror as Mercury died... Smiling with a horrific grin.

"Come here....".

"I want to hear you scream!".

Y/N began walking towards Salem, she began sending more Grimm, but they all refused, too horrified. Finally, several brave Grimm got in front of her, and attacked.

Digging the end of the crowbar in the head of one Ursa, he then proceeded to press his thumbs into the eyes of an Beowulf. Finally using a smoke bomb, Y/N dove forward and tackled Salem, she struggled, the end of the crowbar touched her cheek.

"What's the matter?".

Salem
"Get off me!".

A nightstalker appeared and impaled Y/N, and launched him across the area. Salem got up, dusting herself off.

Salem
"Finally... That's over..".

"Who.... Says it's...Over?".

I got up, the real me, not the other side of me. Salem looked straight at me, like I was a ghost or something.

"You faced that side, now you fight me!"

"You can't fight what you can't see".

Y/N began smoke bombing the area, however, this isn't smoke...It was...It was mustard gas!

Numerous Grimm inhaled it, and began to succumb to the effects of it, although not lethal yet, the pain is certainly incapacitating them. It didn't take long for Y/N to form a thick wall of mustard gas around Salem, trapping her.

Salem
"What....*cough* is this!?".

"Sulfuric​ mustard, try this for size!".

Y/N threw tear gas, causing Salem to cover her eyes in pain. Y/N took this advantage to rig the entire area with explosives, enough to rock the entire city of Beacon and blow the flesh out of the Grimm.

I ran towards Salem, and began hitting her from all sides, she was absolutely defenseless. Somehow, she must have used a Beowulf to push me away, the thing fell to the ground in pain from the mustard cloud.

Salem
"If I'm going down...I'm taking with me!"

A Dragon grabbed Y/N, and hurled him towards Salem, in which she smashed the lower part of his helmet, the gas mask part. Y/N was left with no choice, but to set off the explosives.

Ruby
"Y/N!".

Looking towards my side, I saw everyone, screaming for me to get out, but Salem had a grip on me, and I would pass out from carbon build up from holding my breath too long.

Everyone tried to get my out, even an Atlas mech barged in, but a Ursa got in it's way, and forced it to back away.

Y/N had no choice, and detonate the explosives, the entire area went in flames, everyone was set back from the shockwaves.

Salem instantly vaporized, but something happened to Y/N. Strange blue lights appeared near him, and he was teleported....Out of this universe.

And into the Injustice universe...

Batman from the Injustice universe began calling for help from many universes to fight the regime, however, it malfunctioned​ and caused only Y/N to appear only.

I fell into some old building, looks like a destroyed news building...

Just then, Superman appeared, but he looks different, not the Superman Y/N knew.

Superman
"Who are you, state your business!".

"Tell me first, because i don't know where I am!"

Superman
"I asked first, tell me or else!".

Y/N aimed his pistols, and switched to kryptonite rounds.

"I ain't telling you nothing until I know where the hell I am!".

Superman
"I guess you die then!".

Y/N will be gone for the next two years, fighting off the regime, and helping the Injustice versions of Batman and help the resistance fight the regime.

Back home, many thought he died saving Remnant from Salem's wrath, little did they knew, he will return soon, just two years late is all.
