The hellspawn of remanent (spawn oc x RWBY)

Before we could go back to our annoying hellspawn! We would like attention to the attention to the ground please! Thank you.

It wasn't like nothing before, towards the White Fang they were just grunts, people who think they're close to military, just slightly trained to just dodge a punch.
But these psychos? Unpredictable, one was fighting a huntsman student, then teaming up on them, next thing you know it they push you into the grasp of a ursa and then mauled till the aura shatters so it can down on you for its hunger.
About a handful were gone...
Suddenly a blur of black and white cuts Grimm down, one by one. Blake, slices through each member, as one tries to attack her was met by an illusion of her demise, and a blast exploding from impact onto the hooded men.
As the crowd was controlled besides the huntsmen students grouped together, before the missing girl in yellow was next to Weiss and Blake.

Yang: "Have you seen Ruby!"

Blake: "No! But we have bigger problems!"

She yelled as she continues to fend off by a mixture of slashes and shooting from the barrel of her pistol, Weiss's glyphs causes the hooded figures to slow down for yang to finish them off for her gauntlets.

Sun: "We need hold out until help arrives!"

Blake: "And when is that!"

The group of students yelled as they continued to fend off against the cultists and Grimm.
The military nor other huntsmen were going to help in time, hell if some miracle the white fang tried to save them it'll be too late.
Though there is one option... something big enough to clear the area clean with one hit. An AOE attack.

Weiss:  "I need you all to buy me some time."

She said as with her two fingers on the blade of her Myrtenaster, she closes her eyes as a glyph flickers behind her. Yang asked what she was doing, but Weiss kept repeating herself to buy her time.
Weiss concentrated, a form, a being crawling out of her glyph. Meanwhile Coco's rabbit teammate bursts into the crowd of Grimm and cultist, slicing through by her raw speed, switching through each copy of weapons from her fellow classmates and other huntsmen in training in the tournament. Grimm disintegrated, the hooded people fell as their aura break.
No need for Weiss's secret weapon no?
Suddenly the ground shook, from a far cracking echoed from the mountain afar from vale, a few more rumbles until a screaching cry echoed throughout remnant, powerful gusts of winds approach vale as the griffons soar down as velvet and others tried their best to cover Weiss from her preparation.
Droplets of a black goo hit the ground as a ursa crawled out, then a beowolf, then each pool dissolve as a creature crawled out with a blood curdling cry.
Out of nowhere an overwhelming rush of the griffons and Beowolfs rushed in, claws were flying out, bites finished tried to finish the job but failed, the forces made velvet fall onto the ground with her protective layer shattered, a griffon that was soaring into the air began plunging into the ground, catching a glimpse of death in her sights.
But was it death? No. The hordes of grim was blown away... by a... a blade? A blade, One that was glowing in the light of hope in the darkening hour.
Crawling out of the summoning circle behind Weiss, the armored giant arisen from the ground, swinging their blade talking out countless Grimm in the way while Weiss, huffs and puffs as she collapses to the ground, Blake and yang rushed towards her, nothing was wrong just pure exhaustion.

...

Dashing, slashing punching as the shrieks of metal cry out in the dark, Grimm surrounded the airship for the delicious scent of malice around the boy.
Kicks ran across the shattered allusions head, the blade clashes with the chained gauntlets, the thin but sharp parasol pierces through Aj's body multiple times, each second pass opens new wounds as they closed instantly, each punch thrown and land either shattered illusions or flickering aura, Greedy griffons tried to get a taste of the malice from the boy just for Aj to jump into the air, he blasted a splinter blast of necroplasm towards the Grimm making the chained gauntlet to be traded for the blast.
The glimpse of the glowing armored giant was in the gaze of Aj, his feelings growing concerned for his friends, in which caused him to gain a few new holes. Aj healed back up as the cunning mute smirked, getting annoyed, Aj charged at her, aiming to grabbed her neck. she shattered in pieces once more, Aj met with a barrel of a cane then blasted in the face, knocking back Aj a few feet back before Aj recovered quickly, his claws scratching the hard surface.
