3rd POV
Godzilla bit down on Ghidorah's left head, biting down, making blood fly out. Ghidorah roared out before using its other head to bite Godzilla's leg. The giant bird flew behind Ghidorah to hit it again, but the spiked tails of Ghidorah clubbed the giant bird to the ground.
The gods watched Godzilla and the bird fight against the three headed beast.
Zeus: this is.....incredible.
Poseidon: hey Zeus, I may have a theory.
All the gods looked at Poseidon.
Palutena: what is it?
Poseidon: well you know they boy can transform into a giant lizard, what it others transform into monsters as well.
Zeus: it would make sense.
Palutena: but why would Y/N attack his own then?
Zeus: I.....don't know.
Godzilla roared out, shaking the heavens once again, as Ghidorah used another head and clamped down on his arm. Godzilla's spines began to turn blue, his eyes then turned light blue as well, his growling was heard as he lifted his tail and slammed it onto the ground. Godzilla then unleashed his atomic blast into the sky, hearing his body to a point where Ghidorah let go with its mouth steaming.

Godzilla looked at Ghidorah, then unleashing his atomic right into the giant dragon's chest. Ghidorah roared in pain as it backed away from Godzilla.
Godzilla then roared and charged at the wounded Ghidorah.

Ghidorah roared at Godzilla and then charged at him.

The two collided again, Godzilla roared out, using all his strength and began pushing Ghidorah back. Godzilla's back charged up as he shot a massive blast as Ghidorah's wing, rendering it useless, along with weakening the storm slightly.
The clouds swirled around the battlefield as the two fought, the giant bird slowly started to get up and roared at Ghidorah. It flapped it's wings hard and launched at Ghidorah, using its beak and impaling the three headed dragon in the neck.
Viridi watched the light show just outside the storm, holding the weakened Pit.
Viridi: the presence is still too strong, I can't bring up back.
Pit: h-he's got this....
Pit fell flat on his face after Viridi lost her grip. She quickly went to her knees and rested his head on her legs.
Viridi: take it easy.
Godzilla's eyes turned red with rage, he growled as he grabbed the middle head of Ghidorah and began to pull, lifting the giant and slamming it into the ground. Ghidorah roared out in pain as it landed hard. Godzilla roared again, charging his atomic and blasting it at the center head, decapitating it.  The other heads roared in pain as Godzilla roared and grabbed the right head. The giant bird flew fast and used a skinny red laser and sliced Ghidorah's left head off, only leaving the right one.
Godzilla roared out again before completely ripping off Ghidorah's head. It's whole body twitched before becoming limp. The clouds rose into the atmosphere, leaving the giant bird and Godzilla to look at eachother.

The giant bird landed on the ground and began to shrink, Godzilla did the same.
Zeus: it seems my brother was correct.
Y/N walked out of the smoke, as did a young boy, no more than the age of twelve.
Y/N: so you're the bird?
?????: it's Rodan!
Y/N: how old are you kid, and what is your name?
????: Jax, and I'm 26
Y/N: By the gods you look 12
Jax: I get that a lot, how old are you? 62?
Y/N: hehehe, kid I'm 180.
Jax: what?!
Y/N: yep, I've been transformed as Godzilla for a long time, the transformation messes with how you age.
Jax: I know that.
Y/N: what are you going to do now?
Jax: probably go back to the volcano I guess.
Y/N: you know some people are looking for help rebuilding the town, they could use some monster help.
Jax: what are you going to do old man?
Y/N: well, I have another eating competition.
A light surrounded Y/N and shot him upwards.
