"Now enough talk prepare yourselves to face oblivion"
Nightmare clenches his fists and begins to transform, his purple aura flares all around his body like an unstable wildfire.
"Everyone get back" Qrow said
The air then suddenly starts to feel heavy,hot, and moist the clouds in the sky then start to distort and spin like a cyclone.
"This is not good" Oscar said
"Agreed" Ozpin responded
Nightmare then starts to laugh maniacally as lightning bolts strike near him.
At Beacon Raven Branwen notices the unnatural cloud formation and thunderstorm she instantly realizes that Yang and the others are in critical danger.
"Oh no the others are in trouble I need to go help them"
Raven then flies off to aid them in their perilous battle.
"Where the fuck are you going?" Adam calls out as he stabs a Ursai right through its skull.
The lightning and thunder then stops briefly Nightmare's body continues to glow. The others look on in suspense and absolute then suddenly screams as his entire body starts to crack like a statue, he then seemingly explodes his purple energy flares like the sun itself.
He continues to scream as the night then suddenly changes to day then night several times before becoming dark again with the sky gaining a reddish tint.
"I can't see anything" Winter said
The light and smoke then clears to reveal Nightmare has morphed into a dark black hairless humanoid lizard like creature about Yang's height with a streamlined but still quite muscular physique with razor sharp clawed fingers and toes.
He also possesses white sections on his head, shoulders, forearms, abdomen and shins. His spikes have disappeared as well as his irises and pupils creating pure purple eyes complete with a black lizard like tail 5 or 6 ft long with a sharp white tip.
Nightmare then flexes and examines himself as he becomes absorbed in awe of his power.
"What…is that" Sun said baffled
"His true form the one he was born in" Ozpin tries extremely hard not to cower in fear.
"So do you want to continue to suffer my wrath or die? because quite frankly I like both" Nightmare said
"Just because you became smaller you think you'll get an advantage?" Sun said
"Sun don't" Blake said
Sun then discharges his weapon at the Dark Lord, however his shots just simply bounce off not leaving any sign of injury.
Nightmare unimpressed then lunges at Sun at a very high uncanny speed making him nearly untraceable by the naked eye. He then kicks him in the stomach sending him back several feet.
"Does that answer your question?" Nightmare said
"Sun" Jaune yelled concerned
"He's so fast" Weiss said
"How are we supposed to beat him when none of our hits even do anything" Yang stomps on the ground several times in frustration.
"It's simple you can't your completely out of your league, no matter what you weak mortals do you can never defeat me, it seems like you have all given up already?" Nightmare said
"You're wrong" Blake said
"What did you say mortal?" Nightmare said
"She's right you may be powerful but I don't see anyone backing you up?" Sun said
"And we will find a way to beat you no matter what" Ruby said
"Oh really let's see someone back you up against this!"
Nightmare then flies up and conjures a large red energy ball ready to be thrown at the heroes.
"Oh no" Ozpin said
"I have to admit this was a fun fight, but I'm afraid this is where you say goodbye to your pathetic lives"
Nightmare then flings the energy orb towards them.
However a powerful gust of wind deflects the blast at a nearby building completely disintegrating it leaving no trace of any debris or rubble.
"What who did that you Ozpin?" Nightmare said
Nightmare then looks to see Raven on the ground in front of her daughter and the others with her long red sword glimmering.
"Another bug has come to get squashed" Nightmare said
Nightmare unimpressed then descends onto the ground several feet away from the group
"Mom... You came" a tear runs down Yang's dirt covered face
Raven wipes the tear away with her right finger
"I may have been a very horrible mother and person but I promise from here on forward I'm gonna make it all up to you, your sister, and your friends" Raven said
Ruby smiles
Raven and Yang hug for the first time in her life.
"Thank you" Yang said
Raven turns to Nightmare examining him up and down glaring at him as well.
"So that is the dark god he looks even more ugly then I imagined" Raven said
"He's powerful Raven he's much stronger than anyone or anything we've fought before none of our attacks even scratched him" Qrow said
"He calls himself Nightmare" Weiss said
"I don't know if even a Maiden can defeat him?" Ozpin said
"You created us for a reason Oz I'm not just gonna sit by and let that asshole over there destroy everything" Raven said
"Are you all done with your happy group moments? my patience runs thin and I heard that by the way" Nightmare said as he cracks his knuckles.
"Alright Nightmare I don't care how strong you are, you're going down today"
Raven points her sword at the deity.
"Hmm i never recalled making you mortals so arrogant, After I wipe you off the face of the earth I can resume the real battle"
Nightmare then soars into the sky and conjures a purple and black trident with sharp triangular tips
Raven follows suit by throwing her weapon into the air and catching it after flying 30 or 40 feet into the air. Raven slashes at Nightmare which he counters with his trident.
"I'll see to it that your the last of your disgusting kind Maiden"
Nightmare knocks Raven back with his trident.
"Try me" Raven manifests a somewhat smaller version of her blade with green energy flowing through the hill.
Nightmare growls angrily as he flies towards Raven.
They strike at each other with a flurry of vicious strikes with their weapons until Nightmare knocks her main sword from her hand the blade hastefully plummets to the ground.
"Uh oh dropped your toy?" Nightmare said
Raven flies towards Nightmare and attempts to punch him with her right arm, however he evades the punch with his unnatural speed appearing to have teleported.
"What I had him where did he go?" Raven said
"Right behind you" Nightmare laughed
"How could you have possibly moved that fast?" Raven said
"Wow I make one simple move and your head's spinning you do not deserve to carry the title of the Spring Maiden"
"Shut up!" Raven demanded
"Don't worry I'll make sure your daughter suffers the most before she dies"
Nightmare begins to laugh nearly uncontrollably.
"Don't you DARE threaten my DAUGHTER!"
Raven grabs Nightmare's neck and sends them both plummeting to the ground. Nightmare kicks Raven off they both then engage in a series of physical blows.
"Go... To...Hell"
Raven then kicks Nightmare in the abdomen with both of her legs sending him plummeting to the ground.
"NOOOOO!" Nightmare lands front-facing into the ground seemingly defeated Raven lands near him.
"Huh that's all you got?" Raven said
The others look on uncertain If Raven succeeded in defeating Nightmare.
Raven spits on Nightmare's "body" and proceeds to walk towards the group.
"I think I did it" Raven said
As Ozpin sighs in relief a sudden beam of red energy impales Raven through her side. She gasps in shock as she collapses onto the ground.
"MOM!" Yang screamed
Ozpin and the others look in shock barely registering what is occurring, Ozpin frightened gives Oscar back control of his body.
Nightmare is standing straight up completely unscathed save for being somewhat covered in dirt sadistically smiling and angrily runs to her mother and kneels onto her knees checking her pulse and holding her hand hysterically sobbing .
"You bastard!" Qrow shouted
Ruby stands by Oscar still in shock and anger Oscar looks at her worriedly. Ruby then suddenly hears a mysterious male voice in her head.
"Ruby can you hear me?" The voice asked sounding strangely tranquil, polite, and elegant.
"What who is that?" Ruby responded aloud
Oscar stares at Ruby perplexed.
Raven coughs up blood several times some of it splashes on Yang's leg.
"Yang I love you so much!" Raven then starts to cry as well.
"I love you too please don't leave us!" Yang said
Nightmare then walks towards them smiling at their agony.
"Don't sob girl, I'm simply paving the way for the salvation of your entire race it's nothing personal, well maybe it's personal" Nightmare said
Yang angrily looks up and glares at the deity with tears still streaming down her face.
The rest of team RWBY and the group look at Yang pitifully.
"You fucking sick monster, you call taking innocent lives and hurting people salvation? why I don't understand why are you so cruel and heartless what do you gain out of it?" Yang said
"Well to save us all time explaining I'll give you one simple answer I like it" Nightmare said
An inferno surrounds Yang for a moment as she rockets forward, unleashing a devastating combo of flaming hits and blows on the sadistic god which he continues to evade with his speed Yang unfazed continues her assault.
Weiss, Ruby ,Blake and Oscar then join the perilous fight their hits having little effect on Nightmare.
"Oh shit I forgot, Jaune your semblance now!" Qrow said
"Right" Jaune runs towards Raven and starts the process of amplifying her aura. Raven then starts to gasp for air.
Ruby slashes Nightmare's face with Crescent Rose however the weapon does not even leave a scratch.
"Why won't you maggots just die!"
Nightmare snapkicks Ruby square in the face sending her to the ground incapacitating her.
"Ruby!" Blake runs to Ruby concerned for her teammate's safety.
Nightmare points his right finger at Blake preparing to fire another energy beam. He is then suddenly struck in the back by Weiss and Yang's weapons.
Nightmare quickly turns towards them and snarls angrily.
"Oh no you don't" Weiss said
"You vile filth sucking ANTS!"
Nightmare lunges towards them.
The mysterious male voice then once again contacts Ruby again via her subconscious.
"You must unlock the power of your silver eyes now or all hope will be lost"
"Who are you?" Ruby asked
"There's no time to explain you must wake up Ruby, You cannot let him win, The fate of the entire planet rests in your hands".
