Fight

Godzilla bursts out of the water and he looks around the city of Metropolis.

Godzilla has recently defeated Destoroyah and he has decided to go back to Sollgel island.

But knowing of the distance, he decided to take the short cut by walking through Metropolis.

As he walks, the people screams in terror as Godzilla stomps around the city.

Meanwhile, Superman heard all the screaming and he flies to Metropolis to investigate.

As he flies down, Superman's eyes widens upon laying eyes on Godzilla.

Godzilla turns and upon seeing Superman, he thought to himself

Godzilla: Just who is that guy? Is he picking a fight?

Superman said to Godzilla.

Superman: Your reign of terror ends here monster.

Godzilla lets out a mighty roar and the two charges at each other.

Godzilla attacks first by throwing a punch but Superman dives underneath it and he strikes Godzilla hard in the gut.

Godzilla roars in pain and he throws another punch.

Superman flies underneath it and he punches Godzilla in the face.

Angered, Godzilla opens his jaws and he fires a powerful blue atomic blast at Superman.

Superman grunts in pain as he was blasted back by the attack.

Godzilla punches Superman repeatly before he swung his tail, slamming Superman into a building.

Superman growls in anger and he sped forward, striking right into Godzilla's gut.

As Godzilla struggles, all of a sudden, he felt his feet lifting off from the ground.

It suddenly dawned on Godzilla that Superman is carrying him.

Not going to let that happen, Godzilla unleashes a powerful nuclear pulse, sending Superman flying off him.

As Superman crashes onto the ground, Godzilla lands and he charges up another atomic blast.

Superman rises and he flies up.

But before Superman could punch Godzilla, the King of the Monster ducks and he fires the atomic blast at the Man of Steel.

Superman grunts in pain as Godzilla grabs him and he slams him on the ground.

But it would take more than that to kill Superman.

Superman grabs Godzilla by the leg and he throws Godzilla down.

He then flies up and he fire his heat vision at Godzilla.

Godzilla roars in pain at the intense heat but it would take more than that to damage him.

Godzilla swung his tail up, knocking Superman back.

Superman flies down and he punches Godzilla in the face twice before striking him three times in the gut.

Superman the throws an uppercut, sending Godzilla flying up.

Superman flies above Godzilla and he slams the kaiju down with his fists.

Godzilla tries to fight back but the Man of Steel is too fast for him.

Superman dodges every atomic blast and punches that Godzilla throws at him.

He then punches Godzilla in the face before he fires his heat vision at Godzilla's left eye.

Godzilla roars in pain as he clutches his left eye.

Thinking that he had weakened his opponent, Superman said to Godzilla.

Superman: Surrender.

Godzilla: Over my dead body

Godzilla thinks as he fires an atomic blast at Superman.

Caught offguard, Superman screams as he was blasted back.

As Superman pushes himself up, Godzilla release his grip on his left eye and he waits as his wound heals.

His regenerative ability fixed back Godzilla's tissues and clotted his wound, thus healing his left eye.

Godzilla lifts up his feet and he stamps on top of Superman, attempting to crush Superman with his weight.

But Superman lifted up both of his arms and he caught Godzilla's feet.

With all his might, Superman flung Godzilla high into the sky.

Superman flies at super sonic speed up into the air and he prepares to throw his infinite mass punch to finish the fight.

Godzilla roars in fury and he fires an atomic blast at Superman but Superman dodges and he flies closer towards Godzilla.

With one powerful punch, Superman's fist striked Godzilla right into the chest, shattering his ribs and tearing a hole in his chest.

Godzilla roars in pain as he coughs out blood.

Superman then grabs Godzilla by the tail and he flung him down before firing one powerful heat vision at him.

Godzilla roars as the heat vision struck him, sending him tumbling down into Metropolis.

The city radius explodes and Godzilla roars in pain before collapsing onto the ground.

Superman flies down and he said.

Superman: I've avoided your vital points and knowing you can heal, this attack shouldn't kill you. Now get up and leave my city alone.

Godzilla's chest suddenly began tightening, new flesh growing through his wound before closing, thus granting Godzilla a new chest.

Godzilla roars in fury and he unleashes a nuclear pulse, knocking Superman back.

Superman screams as he crashes onto a car.

Superman grunts as the nuclear pulse knocks him back.

Godzilla then grabs Superman, smashes him twice into a building before he throws him up and he swung his tail, knocking Superman down.

As Superman crashes onto the ground, Godzilla began charging up one powerful red atomic blast.

Superman pushes himself up and his eyes glows red.

It's time to finish this once and for all.

Both fighters unleashes one powerful red blast at each other, creating an epic beam clash.

Both fighters narrows their eyes as they each forces their attacks back towards their opponent.

Superman then concentrates and he fires another powerful blast, pushing Godzilla back.

Godzilla grunts as the heat vision began pushing him back.

But unknown to both fighters, the attack has indirectly sent Godzilla into a nuclear power plant.

Godzilla looked and his eyes widens at the area around him.

He's in a power plant! An area full of radiation.

With that knowledge, Godzilla began to concentrate, absorbing the radiation around him.

As the radiation began flowing into him, Godzilla felt his power increasing, thus giving him the strength to turn the tables of the battle.

Godzilla unleashes another nuclear pulse, knocking Superman back.

Superman's eyes widens in shock and he exclaims.

Superman: What?! Such power. What is this?

Godzilla charges up one powerful atomic blast and he fires it at Superman.

Not willing to die, Superman charges up another powerful heat vision and he fires it at Godzilla.

Now empowered by the nuclear energy around him, the strength of Godzilla's atomic blast has increased drastically and is beginning to push Superman's heat vision back.

Superman widens his eyes in shock as the atomic blast began pushing Superman's heat vision back.

The blast struck Superman hard at Superman screams in agony.

Godzilla narrows his eyes as the atomic blast began incinerating the Man of Steel.

Superman screams in sheer agony as his entire body disintergrated into nothingness.

There was a mighty explosion, causing the middle of Metropolis to explode.
