Reading Reviews:

Fire turtle: Not high, honestly. Considering that the next few chapters are going to be pretty serious.

Onxio: Responding to your comment in Chapter 7, Zero needed someone to obtain valuable info from and things that she normally wouldn't be able to get. Connections are important, so making connections with an Immortal Wizard is beneficial to Zero by a lot.

I DO NOT OWN ANY OF THE CHARACTERS, PLACES, OR INTELLECTUAL PROPERTY THAT APPEAR IN THIS STORY, EXCEPT ZERO NIGIRO, AND THE HOSHIGAN. IF I DID, THIS WOULD BE AN ANIME, NOT A FANFIC.

{POV - Zero Nigiro, Saturday, 2AM}
The school dance had gone on for hours. Some people were still going, but our team, alongside Team RWBY, JNPR, and CFVY were hanging around outside, enjoying the night and joking around with each other. Someone mentioned Ozpin breakdancing for what seemed like the millionth time this night, to which we all exploded with laughter, for what seemed like the millionth time as well.

I'd brought drinks and we were all staring up at the stars, enjoying the night for what it was worth. Meanwhile, I was avoiding looking at the moon at all, lest I become a Great Ape.

"It's so nice outside tonight." Coco says, adjusting her position for more comfort.

"Look at that star over there!" Jaune shouts, as a shooting star crosses across the sky. "Make a wish!"

While everyone chats about what they'd wish for, I take a closer look at said shooting star, before noticing something alarming.

"EVERYONE, SCATTER!" I call out, as the shooting star splits into multiple pieces, as it rains down flaming rocks upon us, Destroying a big portion of Beacon.

"Is everyone alright?!" I cough out, as the dust starts to settle. I hear some confirmation from the others, as the ground starts to shake. Soon, an entire army of Grimm descended upon Beacon.

'What the hell?!' I thought, panicking. 'What could be drawing all these Grimm to Beacon?! An invasion of this scale would require the Fall of Beacon, but timeline-wise, that's over six months away!'

'Although, with my meddling, there was bound to be a butterfly effect somewhere.' I groan to myself, as I backhand an incoming Grimm, killing it in a single blow.

I use the {Heroic Yamato} as I slice through a bunch of the Grimm. Everyone else is struggling, so I'm picking up a lot of their slack. There are Beowolves, Ursa Majors, and a bunch more swarming the Grounds of Beacon.

Suddenly, the ground shakes once more, as a Giant Roar is heard from the Mountain tops.

I glance over, Horrified, as a massive Grimm Wyvern appears above the skies, heading towards Beacon.

[!BOSS FIGHT!]

{Grimm Wyvern}
{The Darkened Herald}
{Level 203}

Using {Superspeed} and {Time Manipulation} to Grab the rest of Team NGSA, as I quickly drag them away from the fight.

"Wha-?! Zeezee?! Why-" Fawn starts, but I cut her off.

"There's no time to explain! I'm sorry I haven't told you guys everything about me, and I promise I'll make it up to you, but right now, I need you to focus on the smaller Grimm while I kill the Grimm Wyvern!"

"Huh?! How are you going to kill that thing?!" Gloss asks, looking at me like I have two heads. "Zero, you're the strongest person I know, but you're going to get yourself killed!"

"Please! Just trust me!" I yell, as I use {17's Protection} over the entire town, causing it to gain levels rapidly. "Please! We need to hurry!"

"...I trust you, Zero." Alice nods, as we make eye contact. Alice swings her Glaive around, as her Stand materializes. "I'll follow you to the end, Team Leader."

"I'm with ya 'till the end!" Fawn says, Brandishing her Axe over her shoulder, reloading it, her antlers glistening in the moonlight. "Let's shred these Grimm to nuttin'!"

"I have my doubts, but I trust your judgement!" Gloss says, as his Clawed Gauntlets protrude from their sockets, water from the Fountain flowing around him in rings.

"Thank you all. Now, you might want to stand back for this." I say, as they take a few steps back. I chuckle, as I shake my head. "You're going to want to stand WAY, WAY further back."

They back up enough that I feel is reasonable, as my hair takes on a familiar Golden Glow.

[{Super Saiyan} ACTIVATED.]
[{Henshin II} TITLE ACTIVATED.]

As I stare at the Grimm Wyvern, it takes Notice of me as I throw a familiar orb into the sky.

"Burst Open and Mix!" I yell, as I feel myself giving into the transformation. I quickly deposit my clothes into my inventory so as to not rip them, as I feel myself getting bigger, and bigger. Golden fur grows all over my body, as I become the same size as the Grimm Wyvern.

[{Golden Oozaru} ACTIVATED. UNABLE TO USE SKILLS, EXCEPT PASSIVE ONES, {Observe}, AND {Appraisal}.]
[{Henshin II} TITLE ACTIVATED.]

I roar at the Wyvern as it roars back. I deck it in the face, sending it sprawling backwards, causing it to crash into one of the border walls surrounding Beacon.

[-482,712!]

Suddenly, I feel something like a needle stab into me, and observe Tyrian Callows below, who stabbed me with his scorpion tail, a Malicious Grin on his face. He then dashes off before I have time to respond.

{Tyrian Callows}
{Killer by Nature}

{Paralysis Resistance} {Passive} {1/100 - 4%} (When the shock is a little more literal. Reduces the effectiveness of Paralysis, and increases the chance of breaking it.}

'Shit!' I think, as the Grimm Wyvern gets back up. I attempt to swing at it again, only to take a huge chunk of damage once my fist makes contact.
I check my stats and inventory, looking for a fix, but ultimately finding nothing.

'That's a lot of AP lost. I might be in some trouble… Shit. I can't use Esuna either because of the Golden Oozaru Transformation. I've got to finish this fast.'

Quickly running through my memories, I remember that there's one skill that I can use, but I've never used it before, so I have to act quickly. I notice the Grimm Wyvern is spawning more Grimm, especially some extremely dangerous ones that I would argue are the most deadly in situations like this. Especially in a swarm of around 150.

{Apathy (Grimm) x 157}
{Level 35}

'I might not be able to use active skills, but I can still summon creatures to fight for me!'

I roar, as summoning circles appear around me, summoning a few friends to take care of the more Troublesome Grimm.

[Cappie]
[Female Mooshroom]
[Growth: Adult]
[Owner: Zero]
[Level 68]

Cappie, bless her heart, has taken over the Mama Bear role for 95% of the animals in my pocket dimension. Therefore, If any hostile mobs or animals decide to cause harm or trouble, she has been there, protecting whoever she can.

She has also never lost a fight with anyone - except me, but that doesn't really count because I was teaching her some things - and that makes her perfect for this.

"[Cappie. Take down those Grimm that look like tall, gangly humans.]" I command as Cappie moos in response. She charges into the Apathy Grimm, causing more destruction than a Bull in a China Shop. She also releases spores, causing many nearby Grimm to grow mushrooms on their heads.

This was actually a move that Cappie learned on her own. She would release spores upon contact, not only draining the opponent's HP to restore hers, but it would also invert their motion controls. If their brain told their arm to move left, it would move right instead, which is why I would even hesitate to fight Cappie nowadays.

I also call upon a few of my own Soldiers.

"[Echos 2-8, Echo Commander, Caller. Appear and Defend.]" I call out, as 8 different Echos appear, immediately taking in the surroundings, and react accordingly.

""{Adaptive Circuits Engage:}"" all eight of them call out, shifting to people I've been familiar with during my time at Beacon.

"{Lie Ren.}"
"{Pyrrha Nikos.}"
"{Nora Valkyrie.}"
"{Jaune Arc.}"
"{Yang Xiao-Long.}"
"{Blake Belladonna.}"
"{Weiss Schnee.}"
"{Ruby Rose.}"

As each of the Echos copy different members of Team RWBY and Team JNPR, the Echo who copied that person joined up with their respective partner.

I continue focusing on keeping the Grimm Wyvern down, as I continue to wail on the Grimm Wyvern, taking a chunk of my AP every time I land a blow.

As I'm fighting the Grimm Wyvern, I suddenly feel a slice along the back of my leg, but ignore it, continuing to punch the Wyvern as it tries to bite and claw at me.

I open my mouth and gather a bunch of my energy, re-creating something I'd seen in a Godzilla Movie once.

I force open the Wyvern's mouth with my hands, and fire a massive beam of energy from my mouth into it. The Wyvern begins to melt, as the heat from the beam is too much to handle.

[-2,103,782!]

[-2,789,324!]

With enough energy, the Grimm Wyvern had had its entire head melted off. I lifted its body into the air with both hands, and roared in victory.

{POV - Third Person, Fawn Aurelia}

Wave after wave of Grimm kept on coming.

Fawn was taking them down no problem, but she couldn't help but sneak peaks at the Giant Golden Ape standing tall above everyone, who had just slain a massive Wyvern-type Grimm.

She knew it was Zero, but a part of her was still in Disbelief. This was the same Zero that almost died to a Nevermore?

Fawn's ears shifted, as she quickly dodged the slash of a sword.

She quickly turned to the danger, and recognized exactly who he was.

"...Adam Taurus." Fawn growled out, tail standing up a bit as it bristled, along with the rest of her hair.

"A little birdy told me that you're the new leader of the Branwen tribe." Adam says, face stone serious, before showing a twinge of anger in a frown. "Your morals make you weak! Humans do not deserve mercy, nor do they deserve kindness! They are a stain on this world, so I will kill you, and take over the Branwen Tribe!"

"Over my Cold, Dead Body, Ya' psychopathic cow." Fawn says, once more preparing her axe for battle.

"I had a feeling you would say that." He reaches for a bag attached to his waist, before throwing it towards Fawn. "This is what happened to the person who had refused to follow me, just like you."

Fawn froze for a moment, before hesitantly opening the bag.

Her eyes became pinpricks, as she threw up a bit in horror.

In Fawn's hands, was the Head of Vernal.

"No…" Fawn says, her hands shaking as Vernal's head drops to the ground, as she yells to the sky. "NO!"

Suddenly, her nails extend outwards, becoming like claws, as Fawn's body begins to change. Her antlers grow larger as her hair grows longer and shaggier, reaching her waist. Her hair changes from a ginger to a crimson, as her teeth sharpen alongside her newfound claws.

"What kind of trick is this?!" Adam yells as he draws his sword, pointing it at Fawn, before scoffing. "Whatever it is, You'll die beneath me."

"Shut up." Fawn growls out, her accent completely missing now. She pounces on Adam at lightning speed, as an actual burst of lightning trails behind her as she knocks Adam to the ground, pinning her clawed hand over his face. "Ground Beef doesn't get to talk."

Adam bites Fawn, causing her to withdraw her hand as it's bleeding. Adam kicks her off, before going for a slash which Fawn dodges by ducking under him. She jumps on top of him again, as she lunges at Adam, pinning his arms down. Fawn's semblance kicks in, and it begins absorbing all of Adam's Aura, before it eventually is all drained away.

Adam is no longer confident that he can win this fight, and he begins to slightly shake.

Like Prey being cornered by a Predator, Adam knew his death was here. He accepted it, but couldn't help but be frightened.

"You're going to die now. Burn in hell, Bastard Cow." Fawn says, about to rip his throat out with her Fangs. Suddenly, Fawn gets surprised as Zero roars in Victory, as she turns her head to look, Adam quickly unsheathes a Dagger covered in a black poison that pierces through Fawn's Aura.

Before the Dagger can pierce her side though, a wire from a grapple hook wraps around Adam's wrist, causing him to drop the Dagger, as Gloss runs over, cutting Adam's head off with his Clawed Gauntlets.

"You're welcome for the save." Gloss says, helping Fawn to her feet, as Fawn takes it, pulling herself up.

"Thanks. 'Ya saved my skin." Fawn nods, before the transformation reverts.

Fawn's Hair color reverts to Ginger, and her horns, claws, and fangs revert back to normal size. She then falls over onto Gloss due to the exhaustion of using a massive amount of power, Knocking him over.

"U-uh- Fawn?! A-are you alright?! C-Could you get up please?!" Gloss asks, extremely flustered at the situation he's in.

"Yeah. M'bad." Fawn says, standing up, but seeming pretty tired.

There's awkward silence between the two as they both stand up, before Fawn decides to take a gamble.

"Ey, Glossie?" Fawn begins, rubbing her hand on the back of her neck. "After all 'dis, wanna… I dunno, get a bite ta' eat together? Or a coffee? Or see a movie?"

"Y-you mean like… a date?" Gloss asks, surprised.

"...Somethin' like 'dat." She nods, looking away a bit. "If ya don't wanna, dat's cool-"

"I'd like that very much." Gloss says, smiling at Fawn, as the two embrace in a hug. "...Now can we please get rid of this body?"

Fawn lets out a belly laugh, as she nods.

"Sure."

[POV - Zero Nigiro]

After the victory screech, I'd checked my health to see that I was technically in the red.

[HP: 135,723,711/1,000,000,000]
[MP: 1,500,000,000/1,500,000,000 (100% Max MP due to Elder Namekian Race)]
[AP: 0/1,000,000,000]
{STATUS: PARALYSIS (TIMER: 0:15:21)}

Letting my body hold completely still while my passive regeneration starts to heal me, I feel the last of the Grimm Wyvern fade to dust in my hands.

[You Have Killed The Boss: Grimm Wyvern!]
[You've Leveled Up! X6]
[You've Obtained a Title!]
[You've Obtained a Headgear!]

{Dragon Skull Mask (Black)} {Epic Headgear} {A must-have in a Fantasy Setting. Grants the {Intimidation} Skill while Wearing this. 50% boost to Intimidation. Intimidated Creatures give 10% more EXP/Gold. (applied before multipliers)}

{Dragon Slayer (Minor)} {Legendary Title} {Proof of your Achievements. Increases Damage done against Enemies with Scales. (This title can be evolved upon killing a stronger dragon.}

After Letting my HP regenerate, I feel that slashing feeling on my body pick up in speed and strength. Before I could even react, I'd lurched over from shock upon feeling a slash around my lower back/waist area, along with the sound of a familiar sniper rifle gunshot.

I turned around in horror, to see someone I'd trusted, someone who I'd done so much for, do something that shook me to my very core. The one part of me that meant the most to me, was now gone. The notifications were proof enough.

[SYSTEM NOTICE: TAIL CUT OFF. REVERTING TO BASE FORM.]
[{Paralysis} CURED DUE TO TRANSFORMATION REVERSION.]
[{Great Ape/Oozaru}, {Golden Great Ape/Oozaru}, ARE LOCKED.]
[YOU CANNOT UNLOCK {Super Saiyan 4}.]

Ruby Rose, Leader of Team RWBY, had just sliced off my tail.

{POV - Third Person, Five Minutes earlier.}

Ruby Rose had no idea what was happening.

Not even 30 minutes ago, she was enjoying time with all of her friends, and now she was fighting what felt like a continuous onslaught of never-ending Grimm.

What's even weirder, is that there was a Massive Golden Ape fighting a Giant Grimm Wyvern. It looked like a scene out of the Godzilla Movies that Yang liked so much.

When the Giant Ape Roared in victory, Lifting up the Wyvern's corpse, Ruby noticed Summer's face going pale.

"Mom? What's wrong?" Ruby asked, lightly touching the side of Summer's arm.

"Ruby, I need your help. We need to take down that Ape. Please, help me." Summer asked, putting her hands on Ruby's shoulders, and going down to eye level with her.

"B-But it killed that massive Grimm-" Ruby starts, before summer cuts her off.

"Please, Ruby. Trust me." Summer says determinedly, looking into Ruby's eyes once more, Silver meeting Silver.

"...Okay, Mom." Ruby says, nodding firmly.

"Thank you, Honey. Now follow my lead." She begins, as they both change into a burst of petals, they start slashing at the weak points on the Ape's body, like the Achilles Tendon, although it's not going in deep enough. Summer then notices the massive tail around the beast's waist, as an idea comes to the front of her mind.

"Ruby! The tail!" Summer calls out, as Ruby climbs up the ape's leg in a burst of petals, reaching the base of the tail, attempting to cut it off while shooting the rifle downwards for more momentum, as the tail manages to be cleanly sliced off.

Suddenly, the Ape's entire body begins shaking, as the beast becomes smaller and smaller. Ruby and Summer back off, grouping up with everyone else as the Grimm begin retreating, strangely.

Suddenly, Ruby hears a familiar voice coming from where the Great Ape once stood.

"nononononONONONONONONO!" Ruby looks over, horrified, as Zero, who has just re-applied her clothes, is grasping at the massive golden tail that is now laying on the ground. Every creature that Zero had called had Disappeared, leaving her alone, hugging against the Golden Tail of the Oozaru.

"...Zero?" Jaune asks with wide eyes, clearly not expecting Zero to be the one who was that Giant Golden Ape.

"Zero? How-" Yang starts, before everyone is immediately assaulted with what appears to be a massive wave of energy.

"HOW COULD YOU?!" Zero screams, her face clenched in anger as her tears begin dropping onto the massive golden tail.

"Zero- I-"

"DON'T 'ZERO' ME! YOU CUT OFF THE ONE PART OF ME THAT MIGHT NOT REGROW! THE POWER OF MY HERITAGE LOST BECAUSE OF SOMEONE I TRUSTED!" She screams her throat dry, as rageful tears fully stream down her face. "WITHOUT MY TAIL, I'VE LOST MY BEST POWER!"

"Miss Nigiro, Back off." Summer says, eyes narrowed sternly at Zero, yet looking remorseful as Zero looks on at Summer with rage. "I was the one who told Ruby to help cut off

"YOU!" Zero roars, and charges forward extremely fast, catching summer off-guard. Zero slams Summer's face into the pavement extremely hard, and causes her body to go limp. "I SHOULD'VE KEPT YOU DEAD!"

Everyone rushes to get Zero off of Summer, but Zero releases a burst of energy, and jumps back. Summer's body being held up by her head, as she goes limp. Zero stands atop the golden tail that had been cut off, as her hair begins to flicker a shade of green similar to a lime. Her Hair becomes untamed and wild, as her hair drops to slightly below her waist. Her hairband is struggling to keep the massive amount of hair in check, as it eventually stops changing altogether.

Team RWBY, JNPR, CVFY, SSSN, CRDL along with Alice, Gloss, and Fawn watches on in abstract horror as Zero, holding up an unconscious Summer by the head, roars into the night, Green Hair Ablaze.

A/N: AND SCENE! Woah, boy, am I sure proud of this chapter! This chapter is one I'd been looking forward to for a LONG time, and I'd planned it since the very beginning. I hope you all will enjoy this as much as I did.

My reasoning for giving Zero Legendary Super Saiyan, was due to the fact that LSSJ is a Mutation of Super Saiyan in the first place. Considering that Zero was a Prototype, and Prototypes are notorious for having faulty parts, or mutations in this case, It makes sense to give Zero the form of Super Saiyan that's famous for being a Mutation of Super Saiyan.

Anyways, Don't Forget to Review/Comment, as that's my Fuel! The More Reviews/Comments, the More I want to write!
