(AN:I'll try 3rd POV this time)
Earth's 3rd World War... Naruto's The 4th Great Ninja War... DBZ Super's Tournament of Power... Pokemon's Pikachu V.S. Mewtwo... Avenger's Endgame... has begun...
2 almost identical 5 year old boys stand against each other in the wilderness looking at each other's eyes.
Rudeus: I have been wronged I thought we were brothers. I've always treated you as one... But why... Why... Why are you doing this.
A boy named Rudeus in his radiating an overwhelming magical powers and said sadly. Everything within a hundreds of thousands of kilometers radius behind him is filled with dense magical power.
Arthur: Hmmph... You don't know how I feel now. I don't have a brother who falls in love with a TRAP!! I-I could have died for you!! You mean so much to me! Why did you have such terrible taste.
On the other side Arthur- Rudeus's elder twin brother- is radiating violent energy crushing everything behind him. The skies are trembling in fear, the Ocean are surging violent waves as high as the sky, the ground beneath can't withstand the pressure and began to collapse.
Rudeus: Rukako is an angel... Even though he's a boy. He's more feminine than most waifus you have! She was even a girl in in the other worldlines so you could say she has two sex!!!
Arthur: Enough about my waifus!! The point here is that he has a D*CK!!!
Rudeus: AND THAT'S WHAT IS GOOD ABOUT HER/HIM!! Then what about you?! Rias Gremory *ptui(spits) she's just a slut exhibitionist who f*cks with issei every night!! Tohsaka Rin? Makise Kurisu? They're just a tsundere! Almost every anime have them!
Arthur: F*CK YOU CALLING RIAS A SLUT!! EVEN THOUGH SHE'S A BITCH SOMETIMES THAT'S WHAT I LOVE ABOUT HER!!! YOU DON'T EVEN UNDERSTAND RIN AND KURISU!! THEY ARE EVEN ABOVE THE GODS OF TSUNDERE HERSELF!! DON'T COMPARE THEM TO ANY TRASH TSUNDERE'S!
YOU LOVING A CAT LOLI, FBI WILL CATCH YOU!! CAT GIRLS? WHY DON'T YOU FUCK A REAL CAT THEN?!
Rudeus: HOW DARE YOU INSULT MY KONEKO-TAN!!
All because of the different opinions of waifus.
Rudeus: Then I have no choice...
Arthur: Yeah... Only one of us will return alive.
After a few moment of silence Rudeus takes the initiative.
(AN: Battle scenes here is bad so read at your own risk)
Rudeus: [10x Fireball]!
10 large fireballs launched to Arthur
Arthur: Hmph... Its meaningless.
Arthur slaps away all Fireballs with hands wrapped in haki. In the next second he appeared behind Rudeus.
Arthur: Your full of openings! *Swing*
Arthur swings his wooden sword at Rudeus's back.
Rudeus: [Body Replacement Technique]!
A log appeared in Rudeus's place and was slashed.
Arthur: Flying... Are you not ashamed?
Rudeus: Magicians fight in a distance so why are you whining?
Arthur: Your right... But don't think you will be safe out there!!
*Arthur sees a future the ground gets muddy*
Rudeus: [Melded Magic: Quagmire]!! [Melded Magic: Fog]!
A thivk fog covered everywhere in the battlefield
Arthur: 'Fog? With my [Observation Haki] this is child's play, he will only cripple himself. He should be thinking he's safe there. Naive!'
Arthur: [Rokushiki: Geppo]
Arthur jumps and stepped into the air like there is an invisible platform.
Rudeus: [10x Stone Cannon!]
Like a shotgun, Arthur was hit by multiple stone cannons.
Rudeus: [ 5x Wind Blade]
Arthur: Where are you looking?
Rudeus: 'what?'
Arthur: Behind you.
Rudeus looks back but before his head was fully turned a punch send him a 100 meters away before stabilizing.
Rudeus: That really hurts.
Arthur: Well... Its not like I'm unscathed too.
Both of their clothes was tattered.
Rudeus: [ Water Style: 10x Water clones jutsu!], [ Earth Style: 10x Earth clones jutsu!], [ Wood style: 10x Wood clones jutsu!]
Arthur: What the hell with this Naruto imitation? If this is earth you need Copyright to use them!!
Rudeus: Shut up!! This is war! Use any means necessary to win!
Arthur: Is that so?
Arthur released his [Conqueror's Haki] for a second.
Almost all of Rudeus's clones have fainted.
Arthur: 'I can't even find the original with my [Observation Haki]… All of them have the same mana signatures.'
Rudeus again launched a preemtive attack.
Rudeus: [Flame thrower!] [Melded Magic: Great Fog]
After that all the remaining clones started to attack Arthur.
All kinds of attacks Wind, Water, Earth, Fire, Wood , Metal was launched to Arthur until all of their remaining mana was drained. The attacks amounts to hundreds of magic spells spammed to Arthur.
Rudeus Did I get him?
Arthur: Hey... Did you just raised a flag?
After a few seconds the dust settles and Arthur was seen Sorrounded by hundreds of small craters.
Rudeus: H-how did you do it? That attack took a quarter of my mana reserves.
Arthur: This not even my final form. *Its a zenkai boost*
Arthur released his [Conqueror's Haki] to the fullest.
Wherever he passed, grass would not grow, the rivers would stop flowing, the mountains would crumble flat. Even some of the beasts who were too ferocious would disintegrate into dust by just his pressure alone.
Arthur: Father said a Saint-Water God ranked swordsman can defend anything even against magic. So you can say I'm already a Water Saint just now thanks to you.
A smile like a predator who found his prey appeared in Arthur's face.
Arthur: I'll will let you attack me for 10 seconds and I will not attack you back. Give me your stringest attack.
Rudeus: Am I being underestimated then I'll take your offer.
1 second passed
Rudeus's Mana is surging in his body.
2 seconds passed
Rudeus: [[Chibaku Tensei/Planetary Devastation!!]]
3 seconds passed
The soil, rocks, and etc. gathered to Arthur like they were attracted by gravity.
4 seconds passed
Rudeus cupped his hand and mana was condensed in his hand.

Rudeus: MEEEEE
7 seconds passed
Rudeus: HAAAAAA
8 seconds passed
Rudeus: MEEEEEEE

Rudeus: HAAAAAAAAA!!!
A beam of mana shoots to a mini planet in the sky.
Arthur: 'F*ck!! Why did a Kamehameha appear here?'
Arthur was truly shocked just now.
Arthur: 'Then I have no choice'
Arthur was freed in the mini planet trapping him by raw strength.
Arthur raised his right hand.
Arthur: I am the bone of my sword
His words echoes to the whole battlefield.
Wild Touki(Fighting Spirit) rushed in his body
Arthur: Rho Aias
A 7 petaled flower appeared like a shield with seven layers.
*Boom*
Dust was everywhere after that attack
Rudeus: I have a little mana left. Even if he's still standing, he would not go unscathed.
On the other side
Arthur: 5 layers broked in that attack huh. I really need to improve my only defensive trump card...
Dust settles down.
Rudeus: What's that shield there? New magic spell?
Rudeus is exhausted mentally since almost all of his mana is exhausted.
Arthur: Rho Aias... I named it after Archer's shield in Fate... Then let's finish this.
Rudeus: I know.
Both of them crouched holding the wrist of the other hand.
Rudeus's hand have a dense spinning sphere of mana.
Arthur's have electricity that crackling an image of a thousand birds.
Rudeus: RASENGAN!!!
Arthur: CHIDORI!!!
After that both of them fell down beside each other...
Arthur's left hand and Rudeus's right hand is badly injured.
The war ended up in a draw.
Arthur: I didn't expect a rasengan there...
Rudeus: hihihihi... HAHAHAHAHAHA!!
Arthur: Why are you laughing there?
Rudeus: Well... I'm going to be Naruto, you will be Sasuke. Who's going to be Sakura?
Arthur: Maybe... We'll meet her soon...
Arthur: 'like Sylphy for example. I might have won the match If I didn't underestimate the rasengan.'
And so the first waifu wars between the 2 rivals and brothers come to an end...
