Here we go guys. A brand new fic that I thought of and wanted to expand upon it. This will be my first crossover and a quite extreme one at that.

Vegito alongside the cast of Attack on Titan within the walls.

Before you ask, no, Vegito won't be nerfed to hell for the sake of plot, but he will be nerfed to some degree as you find out. It's not unreasonable.

I don't exactly have a lot to say so let's just get into this.

Fusion Confusion

The desolate world of Earth has fallen into ruin after Zamasu appeared. He began to purge the world of all human life to satisfy his wicked goal. That goal is to erase all mortals from existence to achieve true peace in the cosmos.

Zamasu wasn't alone, however, he had his future counterpart alongside him with the same dream and goal.

Even the gods of destruction were not spared from his wrath. A supreme kai acting in such a way is unheard of, but there is always a first for everything.

He truly believed that mortals were scum and deserved to erased from existence.

Zamasu just never thought there would be anyone to match him.

He is proven wrong by the fused warrior in front of him.

Vegito.

Zamasu and his future counterpart with his old body fused and became one godly being. The ultimate being in the cosmos. That's what he believed.

He just wasn't expecting this much power and resistance from the beings he called scum and unworthy of their minds.

His body has long since transformed into something evil and vile. The hatred he feels within himself is spewing out and showing its ugly head.

Vegito knows his on the clock and cannot waste anytime, especially since he's in his blue state.

The battle for Earth is underway as a bright white aura is in pursuit of the wicked god.

Zamasu is currently blocking the attacks from Vegito as he is being pushed back. The rapid punches from the saiyan is overwhelming him and the god does not have an opportunity to strike back just quite yet.

"I thought you were supposed to be the ultimate symbol? The weapon of your righteous rage? BUT YOU CAN'T EVEN KEEP UP WITH ME?! CAN YOU?!" Vegito shouts continuing his onslaught of punches and kicks hoping the god will either try to counter or get tired for an open shot.

Zamasu enraged at this mortal's declaration summons more energy and slices upward hoping to cut the fused, but Vegito anticipated sooner or later and dodges kneeing him in the chin sending his head reeling upwards. He follows up with a punch to the stomach and spins around for a kick in the same area sending the supreme kai to a nearby wall leaving himself dented within it.

He groans from the collision but doesn't get the chance to ponder further about it as he sees Vegito charging up an attack.

"IT ENDS NOW!" Vegito roars out to his opponent causing him to snap back at the situation before him.

The fusion skids backwards holding out his hands and then cups them to his waistline twisting his body to the right.

"FINAL.. KAMEHAMEHA!" He shouts sending the yellow spiraling energy in tandem with the blue beam forward hoping to land a direct blow on the deity.

It would have normally worked and succeeded, but this time…

Zamasu caught it and begins to push it back.

He recovered quicker than Vegito anticipated and he desperately tries to push his attack further into the god.

"YOU WILL NOT BEAT ME HERE, SAIYAN! NOW DIE!" Zamasu shouts at the fusion pushing the beam towards him.

The time ring begins to leak energy from the powerful beings struggling with the reverse tug of war.

Zamasu sees this and stares at his hand.

"What's happening?" Zamasu asks in a hushed voice until the time ring shatters causing the beam to distort colors into a blackish purple. The much added energy consumes Vegito whole and before he could answer back in protest, he vanishes.

The beam didn't explode, no cries of agony, or even a body. He is just… gone.

Zamasu is visibly confused at what happened and the fact that his time ring is gone.

He begins to laugh loudly for anyone present watching the battle.

"Just as I thought, no mortal can ever defeat a deity such as myself. There's no one left in my way to enact justice across the multiverse." Zamasu begins to laugh once again.

Both supreme gods look visibly distraught in sorrow for their fallen hero.

"Dad". Trunks calls out physical shaking in anger and ultimately sadness.

"Goku… Vegeta." Tears begin to fall from Bulma's face.

Losing her best friend.

Losing her husband.

Well…

Not exactly.

-TFS-

-Vegito PoV-

Darkness is what I saw before my energy darkened and pushed back onto me.

My eyes feel extremely heavy from exhaustion but I manage to forcefully view the land around me.

I groan aloud as I begin to push myself off the ground and looking around.

A forest surrounds me with a small body of water next to me. Trees as far as the eye can see, but then again, it is densely populated.

My body protests but I stand wondering what happened and then I remember.

'Zamasu. Where is he?' I thought as I begin to try and sense people around me.

I feel a massive amount of people densely populated behind me.

'But this can't be possible! Trunks' timeline didn't have this many survivors.

Feeling like I've stayed here long enough, I set out towards the people I sensed earlier.

Everything is so strange.

'Where is everyone?' I thought again.

The forestation ends as I emerge from the treeline to be greeted with a seemingly large town with a dirt road leading into it.

But what I notice most is the walls beyond it.

'I never seen anything like this before. Was this made after the androids were killed in the future timeline?' Dismissing my thoughts, I began to make my way into town.

'Why is everything much bigger here?' I thought looking towards buildings and eventually people who seemed to tower over me.

I gained stares of confusion as I walk through the streets.

"What's that kid wearing?" One bystander thought aloud.

'Kid?' I ask internally. 'Wait.'

I jog a bit until I see a small section of water and kneel over to look at myself.

My eyes widen in shock as I see myself with… softer… features.

The hair on my head still sticks straight up with my potara earrings still on, but I have much more of a baby face that lacks maturity.

'What the fuck is going on. Why do I look like I'm a 12 year old!' I shout in my head. 'Could this be that change in color and intensity of my beam being pushed back? But what could have caused that?' I ask myself but eventually relent and I turn over staring into the sky on my back.

I finally begin to sense the entire planet for any familiar energy signals, but end up with nothing. There are other humans around the globe, so this can't be the future timeline. That begs the question.

"Where the hell am I and what do I do now? How do I get home?" I mutter to myself and slightly surprised at my higher pitch voice, but that's to be expected.

I am taken from my thoughts as I hear shouting to my right and begin to make my way towards what's going on. 'I don't have anything better to do.' I mutter as I turn the corner and see 3 larger boys in front of a small blonde haired kid.

"So what are you going to do now, runt?" The seemingly leader of the group cracks his knuckles.

"I won't run from you." The boy stares at the trio of older kids and they just laugh.

"More fun for us!" The other boy said throwing his fist forward at the blonde haired kid.

"What do you think you're doing?" I ask as I grab his wrist from the side.

"Armin!" A boy with green eyes and a girl with black hair both shout arriving at the scene.

"You want some too, shorty?" The same kid replies trying to pry my grip.

"Let go!" He demands.

"Like hell we are." The other kid answers aiming a fist for my face but I block it with one finger.

Everyone gasps and I use this opportunity to shove both boys back onto the ground.

"You want some too?" I ask the leader of the shitheads..

"I…" He responds and quickly turns to see the two kids who just showed up.

"It's Mikasa! Run! This freak will get it next time!" The leader shouts running away with his lackeys scrambling to stand up and follow.

"That was interesting." I state dumbfoundedly.

"Hey, thanks by the way." The blonde haired kid perked up smiling at me while the other two kids begin to approach.

I return a smile. We are about at the same height. Not including the hair, of course.

"It's no problem. They just needed to back off." I admit laughing lightly.

"Hey, that was awesome!" The boy with green eyes complimented me as he is accompanied me with a confused gaze.

I chuckle briefly.

"It was nothing. I just blocked their attacks and sent them running home." I answer back.

"I'm Armin Arlert. Thanks for sticking up for me." He smiles holding out his hand.

"I'm Vegito. It's nice to meet you Armin." I shake his hand clearly showing more of Goku's attitude in situations like this.

"Eren Jaeger. That was still impressive to just block his punch with a finger. It shouldn't even be possible!" He smiles brightly towards me holding a hand out as well.

"Mikasa Ackerman." The girl spoke up and extends her hand. I return the gesture smiling brightly at her. She takes a look at my outfit and then towards my arms and blushes slightly.

'He's pretty muscular for being so young.' Mikasa thought.

"Wait, I don't mean to sound insensitive or judgemental, but what are you wearing? It seems incredibly different from anything from around here? Are you from the inner walls?" Armin asks.

"Yeah. I was about to ask that." Eren admits looking at my clothing.

"Inner walls? You mean these walls here?" I ask clearly confused which, in turn, confuses them as well.

"You know, Wall Sina?" Armin asks.

"What's 'Wall Sina'?" I ask scratching my head.

"You have to be jo—" Eren begins but I collapse onto one knee.

"Vegito! Are you okay?!" Armin worriedly asks along with concerned looks from Eren and Mikasa.

'Damn. My fight with Zamasu and reverting back into this small body has made me more tired than I realized.' I thought.

"I'm… fine. Just exhausted." I try to stand up but fall back onto my knee again.

They all come to my aid and tries to lift me up wrapping my arms around Eren and Mikasa.

"Holy hell. You weigh a ton." Eren states, albeit in a strained voice.

"We should get you to Dr. Jaeger." Armin suggests trying to hold him up with Eren.

'His body feels completely solid. What is this guy made of?' Eren asks with Mikasa thinking the same.

"Heh. Sorry. I can try to walk on my own." Vegito begins to walk forward with the trio holding him up.

"You're too exhausted to walk on your own. We're not too far from Eren's house anyways." Armin points out trying his best to support me.

"A-Alright. Thanks." I smile warmly at them.

Mikasa begins to think as she practically effortlessly supports me.

'How does he not know about Wall Sina? Everyone does. Maybe he's just too exhausted to think straight.' She frowns slightly.

At this moment as the four kids make their way back to the Jaeger household.

A friendship with these kids begins to spark to life.

There we go people. The first chapter in the books.

Let me address that Vegito will not act like a Goku clone for long. Vegeta's personality will shift more as he gets older and especially through puberty. His presence is still there and Vegito will still act similarly to Vegeta in some situations as well. This being shown in the confrontation with the bullies. He wasted no time in wanting them to leave.

Also, I may mess up and say Yaeger instead of Jaeger. It's a habit, but don't be surprised if it's accidentally said in future chapters.

I have this story planned out up until Eren joins the cadets, but will Vegito join?

Find out in future chapters!
