A/N: requested by larox764. Enjoy.

You were once a very long living prehistoric marine creature, surviving even the extinction of the dinosaurs and other ancient organisms.
You spent many long years alone as the last living creature of your time.
However, once it reached around the time of the early 1950s, you discovered and devoured some sort of nuclear material, your life changed forever. You became an ever evolving creature.
While it was something you cooped with, it was when you grew legs and walked on land for the very first time, you were met with your own body crashing into things due to the lack of arms and balance.
You heard the many screams of small creatures known as humans, But, You didn't pay much attention to them anyway as you were just moving through the city to move to also find a new food source since things as what you ate in the ocean wasn't good enough.
You needed something better for your taste and to help your hunger.
You would eventually evolve further to where you possessed arms, albeit, a bit smaller and your body would eventually heat up before forcing you to retreat back into the ocean to cool down.

(Timeskip).

After you retreated to the ocean, you would evolve further into the current form you were in. You would go on land again and be met with force from the humans with nearly everything they could throw at you. You were forced to retaliate against them before you were finally frozen.
You stayed frozen for a lot longer than what they anticipated. They decided to try and prevent having to continue the countdown to nuke you, thst was delayed due to you being frozen, by getting many large military transports to lift up your frozen body and drop it in the middle of the Pacific Ocean. Just because you were still frozen, doesn't mean that humanity wasn't safe from destruction. Elsewhere in the sky, a portal from a very different universe had opened up and two mysterious creatures came out of it before it closed. Their names were Gigan and Ghidorah.

Gigan: damn it. How the hell did we let those weak little insects get the better of us?!

Ghidorah: you were getting too ahead of yourself and just cared about torturing most of them besides following my direct instructions.

Gigan: grrr! Whatever, where the hell are we anyway?

Ghidorah: from what I'm guessing, we're in an alternative universe. And an alternate earth, no less. Hmph, idiotic humans, they tried to get rid of us, but only to end up dooming another universe in the process.

The two soon flew off to the city that they were the closest to. Shockingly enough, it was Tokyo, which had finally fully recovered from your attack from so long ago. Ghidorah opened her mouth as her hands charged up electricity before firing 3 electrical streams of her gravity beams on any building, vehicle or person in her sights.

Gigan: time to show these insects hell!

She flew past the buildings with her claws out and slashed through them, casing massive parts of the building to fall and crash any of the humans that were trying to run away.

Gigan: yeah! Just what I love to see!

Ghdorah continued to fire her beams as buildings and vehicles were destroyed and set ablaze as humans were burned or electrocuted to death by the blasts. The city was already beginning to go up in flames the more destruction the two caused.

(Meanwhile).

In the ocean, your frozen body had finally fully thawed and you could move again. You opened your eyes and stood up on the ocean floor.

(Y/N): ugh..... what happened? I feel as if I've been out for so long.

As you said that, something was coming off of your tail. You soon noticed small humanoid creatures, bearing some features like you had, swimming past you and up to the surface.
One of the passing creatures soon moved to you and nuzzled against your cheek before following the rest of them.

(Y/N): where did those things come from?

You soon gave a sigh after a little while and just swam to the surface as well. Once up there, you looked around and saw you were further from the city the last time you came out of the ocean.

(Y/N): well..... I'm a lot further away from land that I......

You soon felt the presence of something coming from land. It felt vastly unknown and new to you. You started to head to the location of the precense and were just wondering through your mind on what if could possibly be.

(Back at the City).

The city had been demolished by the two. The countdown to the nuke that was meant to be on you, was now continued to destroy both gigan and Ghidorah. But, the two were aware of it since they heard the sirens for it going off.

Ghidorah: I knew thst even the humans of this universe would try to pull thst off. Gigan, take care of that nuke. 

Gigan: I'll be on it, mistress.

She soon took to the air and flew to the direction of the skies miles away to where the nuke currently was.

Gigan: you're not crashing our fun. I want to watch them suffer.

She fired a small red beam from her shades and it perced through the nuke, causing it to explode in the sky. Gigan took off and out ran the blast from the explosion before flying a long way back to the city. Once she got back, she continued with her trail of destruction.

Ghidorah: I guess you did well with taking care of the nuke.

Gigan: indeed.

Ghidorah: good. Then we can continue with our.....

Before she could say more, she felt that something was coming close. As did gigan.

Gigan: you feel thst as well.

Ghidorah: I do. And it's already close.

Gigan: kill it?

Ghidorah: not yet. At least, not until we know what it is.

They soon saw a few lines of dorsal fins and a constantly moving tail, poking out of the water as it approached the docks.

Ghidorah: her......

You soon lifted your head out of the water to finally see what it was that you felt the whole time you were getting close.
You saw that it had been coming from ghidorah and gigan, who were both looking at you in surprise, as the Godzilla they faced in their universe, who was female. So seeing a male one was a surprise to the both of them. Gigan even blushed from seeing you.

(Y/N): so it's been coming from those two. Only thing is, just who are they? I've never felt their precense before.

Ghidorah's mind: I never expected this universe to have male godzilla. Especially a kinda handsome...... wait, what the hell?! Even if this is a different universe and gender, he could still be the same damn bitch I had to out up with. Even then......

You soon approached the two, which snapped both ghidorah and gigan from their drooling of you. Ghidorah opened her mouth as her hands charged up again while gigan had her shades glow at the ready.

(Y/N): wait..... I'm not going to hurt you.

They both looked at you confused after saying that.

Gigan: you're joking, right?

(Y/N): oh no, I'm bring honest. I don't intend to hurt you two.

They both stop charging their attacks.

Gigan: who... are you?

(Y/N): I'm (Y/N). I am an ever evolving organism. While it may seem unusual to you both, I can assure you, what I say is true. And while I may look intimidating, I don't mean any attack.

Gigan's mind: ever evolving creature?

Ghidorah's mind: this Godzilla is something completely different all together. I wonder....

Ghidorah: if you're not here to attack us, then why did you come all they way here?

(Y/N): well, this might sound crazy to you, but I just felt this precense that drew me to the direction of you both. Almost like I needed to find you.

Gigan: really?

(Y/N): yes. Very much,

Ghidorah soon got an idea from what you said.

Ghidorah: hm.... could you excuse the two of us for just a moment? I can assure you they we won't leave. I only need to speak with my associate for a moment.

(Y/N): um...

Ghidorah: thank you.

She grabbed gigan's arm as she walked a few feet away from you. The two then began to whisper to each other.

Ghidorah: I have a very special idea in mind.

Gigan: what do you mean?

Ghidorah: we might be able to convince this one here to join us.

Gigan: seriously? You think we can pull that off?

Ghidorah: indeed. He's doesn't once seem aggitated that we attacked this planet. So maybe he hasn't ever dealt with others like us before. We can use that to our advantage and make him ours.

Gigan: hm. Not a bad idea.

Ghidorah: just follow my lead.

The two then walked back over to you, with the tone of ghidorah's voice sounded different.

Ghidorah: you said that our presence is what drew you to Us?

(Y/N): yes, I've never felt anything like it before. I was so desperate to see what it was coming from. Once I saw, I now have this feeling that I've never felt before.

Ghidorah: then it would seem that I was right.

She said as she soon pressed her body against yours, surprising you a bit.

(Y/N): Huh?

Ghidorah: me and my associate, gigan, have felt the same feeling when we arrived on this planet. We new thst we finally found a mate.

(Y/N): a..... a mate?

Gigan: yes.

She said as she wrapped her arms around you while resting her head in your shoulder.

Gigan: but, as we looked for you, the humans attacked us. We merely defended ourselves.

(Y/N): humans...... the same creatures that attacked me once.... They..... thry didn't understand what I was. When they attacked me, I was merely trying to defend myself as well.

Ghidorah: that's the problem I'm afraid. They'll never understand what we are and would rather see us all dead.

She said as one if her many lies.

(Y/N): I don't want any of use to be destroyed because they refuse to understand us.

Ghidorah: (Y/N), do you share the same feelings we do for you. As our mate and lover?

(Y/N): well, when I look at you both, I feel as if you're the only ones who will understand what I am and not make me feel alone.

Gigan: then, will you protect us?

(Y/N): yes. I won't let anything harm you two.

Ghidorah pressed her lips against yours as gigan gently nibbled your ear, all while you gave a light blush.

Ghidorah's mind: with (Y/N) fun out side, this planet will be ours. And nothing will stop us this time.

A/N: I first need to apologize for the being so long. And what's worse, it would have been longer, had I not decided to cut a few parts out to keep it too long. Next, I'm going to have an important question to ask everyone on the next page. And lastly, after the question page, next is Flora x Male Specialist Reader.
