Welp....it's burning Godzilla (not for this chapter though) and your friend for the story is Biollante, so that means you'll have a friend that transforms back and forth from normal female girl to a giant plant

3rd POV
Kids were around, playing on the small little lot of sand they consider a beach. They went into the water to feel that it was practically boiling from so much heat.
Kid 1: what's going on?
A plane was taking off at the airport by them
Pilot: hey what's that in the water?
Co-Pilot: ITS A MONSTER!
A charcoal gray monster came out of the ocean. It then roared and the plane maneuvered out of the way just in time. Everyone in the city saw the beast and ran for their lives. The beast's spines glowed orange as it blasted a building, making it fall, making a plume of soot and ash swarm the city.
Jets flew out to stop it, the creature roared at them. In the distance a 5 year old Weiss watched as her mother held her.
Weiss: Mommy....I'm scared
Kōri: it's ok dear, Sergeant Ironwood will do this
Jacques: yeah! But when he dies we'll all be dead!
Kōri: oh shut up Jacques!
Weiss: what's going to happen?
Kōri: uh......Winter! Take your daughter and get on the ferry
Weiss: what?! We can't leave you!
Jacques: yeah they can't leave us! They are kids! We should go!
Kōri put down Weiss and punched Jacques square in the face. He was on the ground unconscious.
Kōri: you two, go now!
Winter wiped a tear and grabbed Weiss and ran from their mansion. Ironwood was in his jet with a look of determination.
Ironwood: Open Fi-
A tail flew towards Ironwood.
Ironwood: Not my day!
He pressed a button and ejected from the jet before being destroyed by the tail.
Ironwood: BASTARD!
The creature continued destroying the city, Weiss and Winter got on the boat. The monster looked down at the Schnee mansion
Kōri: Be Strong my children
Jacques: what happened?
The monster blasted the house into nothing.
Weiss: NO!
Through the fire the beast stood tall, it then looked over to see the boat leaving. It turned and Weiss was standing on the side, both made eye contact. It then roared, making the waves more violent. It then turned back around and continued destroying the city.
Winter: Weiss.....sit down....you need your rest
Weiss: we lost mom, our brother who hasn't come out of mommy's tummy!
Winter: what about dad?
Weiss: what about him?
Winter: well.....nothing, look, we need to keep looking forward, we'll get revenge for them
Weiss: are all 12 year olds smart like you?
Winter: get some rest....we have a long road ahead of us
As the ship went off the creature roared and left the other side of Atlas, diving down to an underground base. A massive circle door opened, the creature stuck its head in, then was immediately closed.
Beast: *chokes*
A man walked up, he had a piece of metal welded to his face, his name is Tetsu.
Tetsu: very good boy.....surprised you came back
He pulled out a rifle and shot the beast in the face, making it shrink and turn into a 5 year old boy.
Tetsu: Y/N....is the Schnee family dead?
Y/N: yes uncle Tetsu
Tetsu: good.....guess you'll be able to eat tonight
He opened up his satchel and pulled out a piece of a fish and threw it at Y/N's feet. He picked it up quickly and began eating it.
Tetsu: in a few years that form will be perfected....more powerful
Y/N: but....I don't want to hurt anybody else
Tetsu sighed and threw a piece of glass at him, shattering into little pieces.
Tetsu: you better get to bed and rethink everything.....you're a child, you are made innocent, but when you become a real Man, you'll be able to do everything....but for now you dishonor the family....go now
Y/N quickly got up and ran to bed
