Note: AL, Short for Azur Lane.

Godzilla glared at them before firing his atomic breath, only blocked by his Counterpart of himself from Azur Lane Universe. It turns out Gamera brought him into his universe.

Gamera: Azur Lane Godzilla, Welcome to RWBYverse.
Godzilla (AL): Hey guys, how have you been?
Aether: Yeah, we're okay, you?
Godzilla (AL): *smiles* Been Alright.
Kong: That was unexpected.

Godzilla is unsurprised that he saw his other-self.

Godzilla: You don't belong here.
Godzilla (AL): Regardless, Gamera told me what happened here. I'm deeply sorry for your losses, but you're in the wrong side of this.
Godzilla: No one talks me out of this, not even you.
Godzilla (AL): Well, We could be stubborn sometimes. Luckily, I'm here to convince you.
Godzilla: Well then Convince away.

He punched him that send him flying then Godzilla charged and then they clashed. He headbutts him pushing him back, Godzilla (AL) picks up an object and throws it at him. Godzilla charged and an object hits his face. Godzilla (AL) throws him into the cliffs then throws the rocks and pushes him into the rubble, but Godzilla wasn't done. He charged at him, Godzilla (AL) fired his atomic breath and Godzilla did the same. Then the explosion occurred then Godzilla pushed him while charging into the Azur Lane Universe where Azur Lane & Red Axis fought along with Sirens were finishing Project Orochi. Godzilla tried to punch him but Godzilla (AL) threw his punches at him, then he gave a final punch sending Godzilla back into the hills. Godzilla (AL) goes to him.

Godzilla (AL): Stop this, You're tired and injured
Godzilla: Not as injured as you ever be.

Godzilla fired his atomic breath at Godzilla (AL) and punch at him.

Godzilla: You see. I know, your secret, but you were holding back.

He threw him as he charged, he gave two punches.

Godzilla: We always held back, we always use to, But now I don't. Not anymore!

He stopped in front of his counterpart and grabbed him and uppercuts and punches him. He finally finished him off by whacking him with his tail pushing Godzilla (AL) into Orochi and then it exploded, as the Orochi collapses as the dust-covered them. Much to witness to Kong and His Friends and so Did Azur Lane, Red Axis, & Sirens. When the dust cleared off revealing Godzilla (AL) lying on the ground unconscious as his foot were on top of him as Godzilla glared down at his counterpart. Godzilla has won.
