November 4th, 3:00 PM, Tokyo Bay, 1954

The Kamome floated just above where they had picked up Godzilla's radiation signatures. On it, Ogata and Emiko were helping Serizawa and Shinkichi into their diving suits. Serizawa reached down and opened a case containing the Oxygen Destroyer, this time contained in a cylindrical detonator.

"We only get one shot with this." Serizawa told everyone on board. "As soon as it's activated, you are to pull us up immediately."

Ogata nodded.

Serizawa breathed in and out at what was about to happen. He had just dismissed Okimi from his services moments after he left. He even went so far as to tell her to destroy his laboratory and leave nothing behind. When she had asked him where he was going, he simply told her it was some place nobody could follow him. She asked if he was coming back, to which he offered her no answer.

"Are you sure this will work?" Yamane asked Serizawa. "Are you certain this 'Oxygen Destroyer' will dissolve Godzilla?"

"No living creature I've tested with the Oxygen Destroyer has been able to survive," Serizawa replied. "Whether he holds the powers of a god or not, Godzilla is still an animal, so even he has to succumb to it. If not... well, we've just wasted our one and only chance of killing him."

That was a pill nobody wanted to swallow, but it was better than letting Godzilla do to the rest of the world as he had done to Tokyo.

Serizawa made sure the device was properly secured as he didn't want the compound leaking out while he and Shinkichi were down there.

"Alright," he gave the thumbs up. "We're ready to go down."

Emiko made sure to give both men a hug, hoping against hope it wouldn't be the last time she ever saw them again. With that, both men were lowered into the depths of Tokyo Bay. Once they reached the bottom, Shinkichi turned on a light, illuminating the shadowy depths. Both men trudged through the almost alien underwater world. Just then, Serizawa put the Oxygen Destroyer down to make sure it was fully prepped when he felt Shinkichi tapping on his shoulder. Serizawa stopped tinkering with the device to see what he wanted. He noticed Shinkichi pointing at something. He followed his finger and his eye widened.

A few meters away from them, resting against an outer cropping, was Godzilla. The beast was still, sleeping and unaware of the doom approaching him.

"Okay, there he is." Shinkichi told Serizawa. "Now let's detonate the Oxygen Destroyer and get outta here."

Serizawa shook his head. "No, I need to activate the device manually. It's not like in my lab where I had an outside source to activate."

Just then, Shinkichi saw Godzilla's eyes slowly open, his coal-black pupils zeroing in on the two men. He let out a muffled growl and proceeded to make his way toward them. It was at that moment, Shinkichi noticed something about the device. The timer on it was... broken. But that was a mistake, it wasn't broken when they took the plunge then it must have... No. No he couldn't.

"Serizawa," Shinkichi gasped. "You destroyed the timer, why?"

Serizawa chuckled and shook his head sadly. "Ah, Shinkichi. I knew I could never deceive you. You see, only one of us is going to live."

Shinkichi's gaze flipped from Serizawa to the approaching Godzilla, his footsteps stirring up the bottom of the sea and sending wildlife scattering.

"Is that why you brought me down here, Serizawa?" he asked betrayed. "So I could both die?"

Serizawa shook his head again. "No, so that I can."

"I-I don't understand," Shinkichi told him. "What are you talking about?"

"I told you," Serizawa replied calmly. "Humans are weak. Even if I destroyed my notes, the formula for the Oxygen Destroyer is still locked within my mind. It will only be a matter of time until the world's leaders come for me and force me to recreate it. I'm sorry, but it is the only way."

Godzilla continued to close the distance with the two men.

"I want you to do me a favor, Shinkichi," Serizawa told him.

"What's that?"

"Have a happy life." Serizawa responded. "Tell Emiko the same thing. Do it for me."

Before Shinkichi could reply, Serizawa reached up and tugged on his tube twice, signaling for the crew on the Kamome to bring him back to the surface.

On board the Kamome, Ogata saw Shinkichi's cord bouncing slightly.

"They must have detonated the Oxygen Destroyer." Ogata murmured before commanding, "Pull him up!"

The crank immediately got to work on pulling up Shinkichi.

Shinkichi suddenly felt his cord going taut and pulling him back, wrenching him back to the surface.

"SERIZAWA!" he cried as the doctor and monster grew smaller and smaller.

Serizawa then, lifted his device, the sphere containing the compound opening up and releasing a torrent of lavender bubbles that engulfed him and Godzilla. Serizawa watched as Godzilla writhed in pain.

"It's working, Shinkichi." he whispered to no one in particular. He could see his suit was beginning to dissolve as well. In a few moments it would be breached and the acidic liquid the waters of Tokyo Bay was about to become would flood in. He pulled out a knife and cut the cord.

Emiko watched as Shinkichi's helmet bobbed to the surface. He was pulled aboard the ship and his helmet was removed.

"PULL HIM UP!" he screamed at the top of his lungs. "Serizawa is still down there! Pull him up!"

Ogata nodded to the crew manning the cranks. They immediately got to work trying to pull up Serizawa. However, all they could find was a severed cord.

Suddenly, Godzilla erupted out of the lavender foam, his body already showing signs of chemical burns. He let loose an agonized roar into the sky before he sank back down and his visage was engulfed by bubbles. By the time they cleared, Godzilla was nowhere to be seen. Not even a skeleton remained.

"Serizawa... he told me..." Shinkichi gasped, trying to hold back sobs. "He told me that we should have a happy life... for him. The monster's gone... but, he had to take a good man with him."

Emiko dropped down to her knees, tears flowing from her eyes. She didn't realize Serizawa would...

She couldn't hold it in any longer, she began to weep, letting the tears flow like waterfalls.

Yamane just stood silently before speaking.

"I doubt Godzilla was the last of his kind," he spoke solemnly, his voice drowned out by the cheers onboard, save for Emiko and Shinkichi. "If the H-Bomb tests continue, then somewhere, in some other place of the world, we might see the rise of another Godzilla."

And so, with the passing of a great man, humanity and the world at large could live and breathe again, knowing that the terrible monster, Godzilla was gone.

Or so they thought...
