Guys, you will be Godzilla 2003, so you will have the spines like him and human form and transform into that incarnation when you get angry
Y/N POV
It's been 10 years since I've seen my family....stuck in a facility, some nut job has me tested everyday, like I'm an animal. The dick head is named Merlot or something like that. Though he hasn't been around much to torment me, he's been doing shit with Grimm, making them stronger.
James: Y/N.....Merlot wants you
Me: what for
James: I'm in no mood for your shit, if he wants you, you go to him
Me: what does he want from me James
James: he wants you to take out a few intruders
Me: what happened to his mutated Grimm, thought they were strong enough
James: watch it boy
Me: sure thing, fine let's get this over with
Time skip Ruby POV
Me: alright guys, the main lab is through here, I'm thinking Yang and I go through the ceiling, Blake and Weiss go through this vent to the generator and shut this place down
Blake: alright, you ready Weiss
Weiss: as much as I'll ever be, let's get this done and over with
Yang: great, lets bust this place off the map
Time skip into the Vent, Blake POV
I was crawling through with Weiss behind me, making our way to the generator room
Weiss: Blake stop....look in here
I looked through the grate and saw Merlot walking with a guy with large industrial handcuffs, not like police cuffs, more like the ones that are like 5 inches thick with a chain attached to it, anyway, the guy looked beaten, the wounds looked both fresh and old.
Me: what could he be doing with him
Weiss: I'll go to the generator and you follow, I only thought Grimm were here
Me: be careful Weiss
Weiss: you as well
I opened the grate quickly and quietly, managed to drop silently as well and I followed.
Merlot: listen Y/N I wanted to tell you this for months now
Y/N: what is it Doc
Merlot: call me father
Y/N: bullshit you are not my father
Merlot: biological yes, I didn't know your mother was a Faunus
Y/N: I choose not to believe this, now....how do you expect me to take care of these intruders and who are they
Merlot: 4 school girls
Y/N: you cannot be fucking serious
I accidentally took a loud step causing both of them to turn around
Merlot: well Y/N....here is one....take her down
Y/N: take off the fucking cuffs
Merlot: you're right, GO
As he was arguing with Merlot, I got to say, I'm shocked he is a Faunus, he really doesn't have anything, no tail, then again he is wearing a metal suit. All I can see is his (H/L)(H/C) hair and his face, his (E/C) eyes filled with anger. Blake stop it, you have a mission, don't get distracted. I look up to see the metal suit was off, and his back was pointy.....all the way down. He looked at me and ran towards me, Merlot had a smirk on his face
Y/N POV
Me: WAIT
?????: why, you gonna kill me
Me: kinda hoping I can leave with you people, been here for ten years and I'm tired of Merlot, he has cameras watching, just play along
?????: wait what
I tackled her in front of a camera, and made it look like I was smashing her head into the ground
Merlot *speaker*: very good Y/N....return to me
Me: fuck you
Blake POV
I felt and extreme amount of heat coming off his body, I see veins popping and a tail?
Y/N: grab on quickly and tightly, in busting us out, and destroying this place.
Me: how can I trust you
Y/N: unless you want to get smashed, I suggest you get grab on
Me: ok
He was actually starting to get much bigger, his skin became really scaly, the thing on his back were spines and they were growing as well. He broke through the ceiling and he has finished transforming into a....monster, he let out an ear piercing roar (first one in the video)

Ruby POV
Me: what was that
Yang: I don't know, I'm gonna check it out
Yang ran out the door to see what was happening
Yang: Ruby......you might want to come see this
I walked out there and immediately saw what she was talking about. Weiss came out of the door with a big smile on her face, then saw the giant monster
Weiss: what is that? Wait...Blake was in that area
Me: WHAT
Yang: we have to go help her, she's probably stuck under debris
The creature's spines turned blue and an aura appeared in its mouth
Me: what is it doing
(I'm so sorry for the poor quality video, this was the best I could find)

Yang: BLAKE NOO!
