Hi! This is my first FF. It contains Ronin x Nya, fyi. I'll write more stories with different ships later, but I've written this out in my notebook. Constructive criticism is appreciated.

This is a huge crossover, the main characters are from Ninjago, but the enemies they encounter are from Fallout 4 (Bethesda). The whole parabatai thing…that's from City Of Bones (Cassandra Clare). And, I just realized this, parabatai can't fall in love…but they kind of did in this FF, soooo…oops…

For those of you who don't know, parabatai are two warriors, strong when they fight alone, but almost unstoppable when they fight together.

This will contain blood, gore and possibly some language…so be warned.

So I'll shut up now! Please enjoy!

Disclaimer: I don't own Ninjago, Fallout 4 or City Of Bones.

The Story So Far~ the ninja are stuck in outer space (again), while Nya and Ronin struggle to fend off a huge horde of feral ghouls. Ninjago is now a Wasteland. (More information about the bombs will be further in the story.

Nya's POV

As Sensei Wu, Misako, P.I.X.A.L. and Cyrus tried to get the remaining citizens of New Ninjago City into the airplane, Ronin and I were struggling against the feral ghouls. We were highly outnumbered.

"Come on, sweetheart, just a few more!" Ronin yelled, fending off a charred feral and decapitating it. I rolled my eyes and threw a fragmentation grenade into a crowd off charred ferals, while yelling at Ronin to take cover. We jumped behind a car as it exploded, then hopped back out into battle.

"How's REX?" I yelled.

"Five minutes!" He responded.

This is our only chance to make it out of here alive.

A black figure with orange-ish eyes threw itself at me. I grunted, but managed to worm my way from under its weight and thrust my blade into its thick neck. Blood poured out of the wound. It wasn't enough to kill the thing, but it was enough to stagger it. I took this opportunity to shove my sacrificial blade into its forehead. I shoved the ghoul off of me and stood up.

Ronin was with REX, shooting off ferals. There wasn't any time to waste. I jumped on top of a car and leaped from car top to car top, until I had made my way to REX.

I jumped once more, grabbing Ronin's outstretched arm. He pulled me up and into REX.

I regained my balance and looked into his eye.

"Thanks," I said, out of breath.

"No problem, sweetheart. Nice job out there."

He embraced me.

"Let's go see Kasai," He said, his breath tickling my ear.

"Yeah," I agreed.

I think he's a handsome man, really.

Even though he's nine years older than I am, and we're a couple, I love him. I love his intense orange-brown eye, I love his smile. I especially love how I'm the only one he calls sweetheart. His mind is open for both good and evil intentions, his judgement…I love everything about him.

Everyone thinks it's weird, because he's nine years older than me, he was a former mercenary and thief, and I'm a twenty-three year old woman. The ex-water ninja. I was supposed to love the dear lightning ninja, but that hadn't turned out too well. People thought Ronin wasn't good enough for me, that I should've stayed with Jay and forget.

But I couldn't deny it. Everyday Ronin was with us, I found myself talking to him more and more often, and missing him more when he was gone.

And when he first kissed me…it was perfect. Ronin's kiss had been angrier than Cole's, but not nearly as desperate as Jay's.

Soon after, I left the ninja. And I had reason to. They had treated more like a prize than a woman.

Ronin…he wasn't like that. He never left me out of a story, unlike the ninja, he talked to me, treated me like a woman should be treated, and he didn't underestimate me just because I was female. He had good judgement and common sense.

A few months after I left, Ronin and I were married and had a baby. She's two months old, and her name is Kasai. When she was born, and I held her for the first time, her fiery orange-red eyes reminded me of Kai's eyes whenever he was around his element. I think she'll be like her uncle. She was also born with a rune (A/N~ In case you don't know, the runes I'm talking about are basically tattoos that give you some kind of power forever, or only for a limited amount of time, but in this case, it's permanent.) that Ronin and I both had tattooed on our shoulder blades a while ago. She's destined to have a parabatai.

A parabatai bond is rare these days, and Ronin and I almost died (according to Misako) getting Bonded. It's dangerous and only those born with the Mark can establish a parabatai bond.

I remember the day Ronin and I found out we were parabatai. It was a warm, sunny July day at the tea shop, and I had been out training my newly discovered element. My gi had gotten soaked, so I had changed into a dark red muscle top with dark blue leggings. The muscle top had exposed part of my Mark. On that same day, Ronin happened to be strolling around, and he caught sight of my Mark.

"Whoa, sweetheart! What's this?" He had asked, tapping my shoulder. (Where my Mark was located) He traced his rough hands over the ink of my Mark. His touch had caused me to completely freeze up.

"I-I was born with it." I said, still enjoying his touch.

"Hmm…you know what it is?"

"I looked into it, but never found out. Why?"

He pinched the fabric of my top.

"Do you mind if I look?" he asked.

I shook my head, feeling the heat rush into my cheeks. He lifted the fabric, and my heart beat faster. His finger traced the Mark and my skin. I could feel his sharp gaze, as his hand slid on my skin.

Finally, he spoke.

"Sweetheart…" He turned around, and I almost passed out when he started lifting his shirt up, revealing his muscled back…tanned skin…scars…

…and the exact same Mark I had.

"…I was born with it as well." he said. I couldn't resist; my hand shot out and touched his Mark. I remember feeling him tense up like I had. But he didn't pull away.

"Like what you see?" He asked, but his tone had lost its cockiness and confidence. I didn't answer. I couldn't.

A few moments later, I dropped my hand and decided to talk to Misako about this ordeal.

"We need to find out what this means!" I said, and walked away.

Well there ya have it! Hope you liked it. Next chapter will be Present Day, and you'll meet little Kasai! xD. If you stuck through this chapter, you get a free jar of Nutella! *hands you Nutella* YAAAAY!

Btw, the thing that attacked Nya was a Ghoul, NOT a zombie. The difference, you ask? Ghouls in Fallout 4 were once people, like zombies, but radiation rotted their brains away, causing madness…

I'll be working on the next few chapters! I won't be able to update on Sundays, or next week. I will try my best, though.

Constructive criticism is always appreciated. Please review!

Thanks for reading!
