3RD PERSON POV

Y/N5: I'm detecting a massive burst of energy from the portal.

Hank(MT): If anything comes out to attack us, we'll handle it!

BBQ(MT): YEAH!

Kirby: POYO!

Ozpin(MT): Alright.....

A portal opened in the middle of the forest and they all surrounded it the next day, ready to attack whatever was behind it while Y/N5's girlfriends stood behind him.

Akame: Alright........

Revy: LET'S DO THI-

Y/N: The hell is this?

Y/N walks out of the portal, rubbing his head while wielding Yamato and looking around to find dozens of huntsman standing there.

Y/N: *phone* Seems like an alternate version of Remnant. Can you come along?

Hank, Ink and Bernadette hop out of the portal, the latter prepared to fight her way out of there as the alternate headmaster steps forward.

Ozpin(MT): Are you perhaps the ones living behind the portal?

Y/N: We are. I-

Hank(MT): HOLY SHI- IT'S ANOTHER ME!

Another Hank runs forward and Y/N's Hank grins, giving him a high five as they bro hugged.

Hank: ANOTHER ME! LET'S GO!

Bernadette: So there is another me as well.

She stares at her counterpart while Y/N walks forward to meet Y/N5.

ANALYZING SUBJECT Y/N NUMBER 005

SUBJECT ALSO HAS IMPROBABILITY DRIVE

SUBJECT Y/N #005 IS STRONG

Y/N: Your name is Y/N right?

Y/N5: How...... Are you Y/N?

Y/N: I am. Our world of Nevada at the moment has 20 of these portals, and we are merely making sure there isn't any threats behind it.

Y/N5: We aren't threats.

Y/N:.......Hmmm........I'm curious.

He looks at Y/N5 before grinning.

Y/N: I'm curious to know how strong you are.

Later

Bernadette(MT): Your eye....

Bernadette removes her eyepatch, revealing her missing eye while her arms were riddled with scars.

Bernadette: My world was destroyed because of God's death. I was hunted by the tyrannical empire of Y/N's world so I joined their forces.....and in return, I lost my eye due to battle along with gaining my scars.

Bernadette(MT) touches her cheek, seeing the guarded look in her eyes as Y/N stood apart from Y/N5 in another world.

Y/N: So we're fighting. Sword or fist?

Y/N5: Any is fine.

Featherine: Hello mortals~ Gods~ Today we will be commencing a spar between Y/N and Y/N of Remnant. Two dimensional travelers.....You can go all out. Devil Trigger, Lord of Cinder, KI, weapons, anything goes. I'll take responsibility for fixing the damage~

The whole world shifts so that the spectators were watching from a barrier.

Y/N5/Y/N: Anything goes huh......

Featherine: BEGI-

COPYING INFINITE PUNCH

COPYING KYOKUSHIN KARATE AND RENEWAL TAEKWONDO

*BOOM*

Y/N copies Y/N5's move before they clashed fists, the planet they were stationed on exploding as the two were now in outer space with the spectators protected by a barrier and such.

Y/N5: Yes.....

Y/N5: I CAN GO ALL OUT FROM THE VERY BEGINNING!!!!

Y/N: THEN COME AT ME!

SUBJECT Y/N AND SUBJECT Y/N #005 RELEASING 100% OF POWER

*BOOM*

Their blows shook the entirety of the space and time, millions of blows exchanged in mere seconds as they went at it. Punches smashed against Y/N's body all at once, yet he had a grin on his face as he returns each blow back.

Y/N: *grin* YOU DON'T KNOW HOW LONG I WAITED TO FIGHT LIKE THIS! TO MEET SOMEONE THIS STRONG AND JUST LIKE ME!

Y/N5: I KNOW!

*BOOM* *BOOM* *BOOM*

*BOOM*

The entire universe they were in blows up from the shockwave and they all land onto another planet with the spectators as more people show up to watch in the stands.

Y/N(AAU): What the-

ACTIVATING SIN DEVIL TRIGGER

*WHOOSH*

Y/N: SHOW ME MORE OF YOUR POWER!!!!

*WHOOSH*

Y/N5: FINE! LET'S DO THIS!

*BOOM*

Millions of solar systems were obliterated by the collision of their punch, their speed so fast they traveled to the nearest universe with their sheer speed.

Y/N: CCCOOMMMMMMEEEEE OOOOONNNNNNNN!!!!!!

He equips Gilgamesh before leaving billions of afterimages around the space next to Y/N5, confusing him before-

*BOOM*

He was bombarded with millions of punches that excites him even further, and using his legs kicks Y/N through a portal. Y/N lands onto the ground, laughing before charging at Y/N5 with his fist reeled back while he does the same.

Y/N5/Y/N: AAAAAAAAHHHHHHHHHH!!!!!

Auditor: BOTH OF YOU!

Their punches freeze before they turn to the Auditor who stood there, rubbing his head exasperated while Y/N's family had a shocked look on their face.

Auditor: I heard from Featherine you're sparring Y/N with your counterpart, but next time control WHERE you're going unless you want to blow up an entire planet.

Y/N:.....Oops.

Ave: *giggle* Aaahhhh.....

Y/N perks up before running to his wife who held Ave.

Chelsea: Is that you?

Y/N:......Ah....I was planning to use a different transformations. Uh....this is what you call my sin devil trigger form.

He transforms back before Chelsea hands him his baby.

Y/N: *coo* Aw who's a good girl~ You want to meet other people?~

Tatsumi:......You gotta train us bro.

Y/N: Later. But now I have to talk with someone at the moment.

Akame3: M-Mine? S-Sheele? L-Leone? T-Tatsumi?

Y/N looks ahead to find Y/N5 and Akame staring at his family with tears in their eyes.

Y/N: Wha- oh...........Aw....yeah.

Chelsea: Y/N where are you going?

His wife and girlfriends follow him out of the clearing when they heard loud sobbing from behind them.

Y/N: Do you know......did you see the scars on them?

Makima: We do. The other Y/N and this Akame seems to have MANY scars on all their skin.

Eto: They must be from a lot of fighting right?

Y/N: No.......that's not from fighting.

Everyone: What?

Y/N: From the way they reacted, they miss Night Raid a lot. The scars aren't from fighting....I seen those before.

Y/N: They're from torture. The other Y/N.....I saw his mind....he went through a lot of things.

He peers behind a tree to find Y/N5 and Akame3 hugging his family, sobbing loudly.

Y/N: It's time we learn about each other.

Later

Y/N: Are you alright or do we need more tissues?

Y/N5: *sniff* N-No...

The other Y/N sat with his girlfriend....and apparently his past mom and dad with a little version of him while Y/N held Ave and his wife, family, and girlfriends crowded around him.

Hank(MT): Damn....you're not the only Y/N with multiple girlfriends Eh?

Y/N5: How many is......that?

Y/N: 20 girls. I got 2 combat androids, a dragon god, an assassin's daughter, my assassin wife and her counterpart, my former best friend that's also a former assassin, a feared general of our army, your counterpart of Eto, a supersoldier, a mercenary and mob boss,  a biological mutation virus incarnate, a literal devil, devil hunter, the electro archon, a servant class saber who was a former ruler of her kingdom, archangel, Valkyrie, and a god that can erase me out of existence along with this entire plane of existence in a split second.

Eula2: That's......a rather unique group of partners.

Carson: Who does the baby belong to?

Chelsea: Me! I'm also his wife!

Lily: And you have girlfriends too?

Y/N: It's a rather complicated matter.

They all introduced their names as Rover rolls onto Kirby.

Y/N5: Are you......a soldier?

Y/N: I am.

Roberta(MT): There's quite a lot of soldiers and such around. Are you at war?

Y/N: The original world where I'm from is in a bloody 1000 year war. Population 1000 years ago, 76 billion. Now, 24 billion.

Velvet(MT): H-Half the population?

Y/N: It's that bad. I've been playing a key role in their victories. My specialty is swordsmanship.

Y/N5: Yet you can copy my blows.

Y/N: Even without my powers, I know how to fight with my fists.

They all talked amongst themselves, wanting to know more about the other.

Y/N: You got 8 girlfriends? Huh.....that's nice. How long have you all known each other?

Everyone: About a year.

Y/N: Why don't you marry them?

Y/N5 chokes on his own spit while all their faces turn red.

Kobeni: Y-You can't say that so casually!

Y/N: What? They all seem close and his parents already gave their blessing.

Carson/Lily: *smirk* Indeed.

Little Y/N: *happy* I can't wait to be an uncle!

Bernadette(MT): *red* 'C-Children?! I mean.....'

Himeno(MT): 'Fu Fu~ I don't mind having you as my husband darling~'

Y/N: You have the perfect life. A home, a world you can live peacefully in, friends, family, money......you have everything.

Y/N5: But there's yours.

Y/N: ???

Y/N5: I want to help your world!

Y/N: Are you sure?

Y/N5: I know I'm not a soldier like you.....

Y/N: I know. You weren't a soldier that fought in the battle field from the age of 7-18. You weren't a soldier that killed more than a hundred million people. You weren't someone that had no childhood, no parents, no siblings and friends as a little kid........but you're strong and have good conviction. If you want to help, wait 11 months.

Carson: W-Wait! Are you saying he's going to fight in your war?!

Y/N: The threat we face is incomprehensible. I'm not even sure I can defeat him.....and Y/N here.......I'm surprised. He has potential to even match me in power. If he doesn't want to help, I'm fine. If he wants to, fine by me. He's a full grown adult and made many good choices, so trust your son...........

Lily: O-Ok. I see.

Y/N: I'm pretty sure we won't have any issues, but can I ask where this rift is?

Y/N5: Next to my home?

Y/N: *nod* There we go. We'll have no issues. If you want to visit my family, you'll know my address. But for now......

He gets up and shakes his hand.

Y/N: Do whatever you like around here. I'm sure we can be friendly with each other.

Eto/Eto(MT): YAY! BESTIES!

Y/N5: Heh....*grin* You still owe me that fight.

Y/N: We can fight inside our minds you know. I can just link my mind to yours and we can duke it out.

Y/N5: DEAL!

After looking into his mind, Y/N was impressed to see his counterpart had his fare share of dimensional traveling, even more than him along with more experience with his otherworldly powers. He was interested in learning from him even along with his powers as they head off to exercise together.

Carson: He must be a caring husband huh. How old is the baby?

Chelsea: *hugs Ave* Due to Featherine's Uh....shenangians, she's 4 months physically. But yeah....she's a healthy baby....

*BOOM*

Ave grabs a ball and throws it, blasting a hole through the wall and knocking down a stop sign implanted onto the ground 50 feet away.

Leone: It's a strong baby.

Akame3: *hug* Mmmmm.......

Sheele hugs the alternate Akame, already knowing what happened to her and wanting to comfort her.

Y/N/Y/N5: LET'S DO THIS!

They both ended up fighting so hard within their minds the damage transferred to their bodies real life and had to be hospitalized for a day with their girlfriends respectively chewing them out for being reckless.
