Naruto VS Honkai Impact 3rd. Today we have two anti-hero lightning deuteragonists and the best friends of Naruto and Kiana coming in for a showdown that will end in death. Only one will survive.

Interlude

(*Cues: Wiz & Boomstick - Brandon Yates*)

[There should be a GIF or video here. Update the app now to see it.]

Shadow: Sasuke Uchiha, the Sole Surviving member of the Uchiha clan and surrogate brother of Naruto Uzumaki.

Zero: And Raiden Mei, the Heiress Empress of Lightning and love interest of Kiana Kaslana.

Shadow: Like most deuteragonists we've seen in stories like these two are cold, bitter, alone, and and dreadful determined they will do whatever it takes to gain more power to reach their goals.

Zero: Even if it means they have to stab their friends especially the main protagonists who they have a strong bond with in the back to do it. He's Shadow and I'm Zero.

Shadow: And it's our job to analyze their weapons, armor, and skills to find out who would win a Death Battle.

Sasuke Uchiha

Shadow: Among the clans of Konoha, the Hidden Leaf Village few are as powerful as the Uchiha clan.

Zero: Yeah I mean they are both incredibly skilled ninja, are the founders of Konoha, and are great prodigies for the most part.

Shadow: One of those Uchiha we are talking about is none other than Sasuke.

Background
Full name: Sasuke Uchiha
Age: 32
Height: 168 cm
Weight: 52.2 kg
Nature affinities: Fire & Lightning
Shadow Hokage of Konohagakure
Affiliations: Team 7 (formerly), Akatsuki (formerly)
Likes: Naruto Uzumaki, Itachi Uchiha, Sakura Haurno
Dislikes: His mistakes, losing friends & family
Favorite band: Linkin Park

Zero: Sasuke was just your average young and optimistic kid growing up alongside his older brother, Itachi, who was his great role model and caring brother to him.

Shadow: But though Itachi would usually be away on multiple missions assigned to him by the village and has big responsibilities as the eldest son of the head of the clan.

Zero: But regardless Sasuke still wanted to be greatest shinobi ever just like his bro.

Shadow: However things started taking a dark turn, Itachi suddenly began to grow darker and bitter and sick and tired with the clan's traditions and was even accused of killing fellow Uchiha clan member Shisui. And when night rose when Sasuke returned from training he found all of his clan members dead including his parents and Itachi standing over their bodies and that's when things get started to get VERY clear.

Itachi's killing spree is shown, with many clan members in pure terror.

Zero: I'll say! He went and murdered all of 'em! Every last one! Except for his kid brother, Sasuke.

Shadow: Turns out Itachi wasn't exactly the caring brother Sasuke thought he was.

Zero: Yeah the rat bastard liar killed all of the Uchiha just so he can test the limits of his ability and only left Sasuke alive just so he can test his abilities on him later. Talk about Top 10 Anime betrayals.

Shadow: This event traumatized and changed Sasuke's life forever and would ultimately result into him being outcast from society just like his soon to be best friend Naruto Uzumaki. Angered by his brother's betrayal and fueled with a desire to grow stronger, Sasuke valued to kill Itachi and avenge the Uchiha clan from then on he was an avenger.

Zero: And he'd make it happen no matter how far he has to fall.

Shadow: As a ninja Sasuke is a master at using three primary kinds of Jutsu, or ninja techniques.

Zero: Ninjutsu which is basically a complete of magic spells like walking on walls, ceilings, and water, Genjutsu messes with the senses of one's mind, and Taijutsu which is hand to hand combat.

Shadow: Alongside these skills Sasuke has mastered his several Ninjutsu techniques like making a few Shadow Clones, substitution jutsu, and primary elements like fire and lightning.

Zero: He can use multiple fire breaths and his signature technique the Chidori which is a ball of freaking lightning.

Shadow: Thanks to the teachings of his teacher Kakashi, Sasuke can use the Chidori into how hands or a weapon like his sword and kunai and becomes capable of cutting through just about everything.

Zero: Hell it can even cut actual lighting in half.

Shadow: Sasuke can also use the Chidori to increase it's size making it into a much larger spear or shoot out smaller versions of it, he can even cover his entire body with Chidori making him a living sword, and lastly his strongest Lightning Release technique is Kirin a large lightning dragon used to cast down judgement on those he deems wicked.

Zero: Damn Sasuke is a damn pro so don't try and mess with him or his teammates if you know what's good for you. And we haven't even covered his best weapon yet.

Shadow: Thanks to the traumatic experiences of the Uchiha Clan massacre and trying to back up Naruto in the Land of Waves, Sasuke can use the Uchiha's signature weapon: The Sharingan.

Zero: Don't let these eyes fool you they may look cool but these eyes allows the user to copy ninja techniques as well as predict their movements.

Shadow: And with a single glance the Sharingan can trap anyone in a Genjutsu and even worst it's easily the most powerful genjutsu of the entire ninja world.

Zero: With the Sharingan, Sasuke can not only increase his strength and speed but he can see a person's chakra down to the cellar level, enter people's consciousness to restrain chakra, read minds, and restrain movements.

Shadow: While Sasuke at first glance could barely handle one tomme he eventually mastered it to the point where he can use all 3.

Zero: Despite his quest for vengeance Sasuke eventually soften up with a squad of comrades including the knucklehead ninja himself Naruto who was like a brother to him. Though Sasuke didn't admit it.

Shadow: However after a reunion with Itachi, and realizing that Naruto was catching up to him in power Sasuke realized he was falling behind and needed to get stronger in order to achieve his goals.

Zero: And he found the best solution: Join a rogue ninja named Orochimaru who offered him power, but to do this Sasuke would have to betray his friends and that's exactly what he did Naruto obviously isn't too happy about so he ran after him to get him back and so they threw fists.

Shadow: Despite Naruto's best efforts and being evenly matched, Sasuke was able to defeat Naruto and joined Orochimaru to train under him.

Zero: Then he killed Orochimaru and finally engaged in his battle with Itachi.

Shadow: And in that battle Itachi fell and finally died in battle. After years of torment at his brothers hands, Sasuke had finally killed Itachi, avenged the Uchiha clan, and is finally free and is at peace at last.

Zero: Or did he! Because it turns Itachi, gasp, was a good guy all along!

Shadow: Okay okay this is where things get crazy as stated by Obito, Itachi didn't massacre the clan just for the sake of it he did it to protect the Lead village as the Uchiha were planning a coop to take over the village due to their mistreatment as they were outcast and cut off because the Elders feared them.

Zero: All because one Uchiha used the Nine Tails to attack the village, and the higher ups feared the Uchiha so much that they refused to have them help against the Nine Tails. I feel like they were planning to eliminate the Uchiha from the start.

Shadow: They were especially one of the advisors Danzo Shinura who went to every lengths to make it happen.

Zero: Remember that dude Shisui yeah Itachi didn't kill, he killed himself because Danzo took his right Sharingan eye and had his men poison him so that Shisui wouldn't use clearly wouldn't use a better way to stop the Uchiha coop. Dude loves murdering innocent lives so much so that he made Itachi do it by threatening to kill Sasuke all so he can take more Sharingan on that terrifying arm of his. Damn talk about a rough break.

Shadow: Saddened and angered by the loss of his brother who actually loved him and the constant mistreatment of the Uchiha, Sasuke once again swore revenge against to kill not just the elders but the entire Lead Village to make them all pay for Itachi's suffering.

Zero: Ugh those are innocent lives he's murdering by the way, despite the fact that most of them did nothing wrong and had no involvement with Itachi's suffering yet they all have to pay for Itachi's death for what a few people did. I know it's karma for the village blaming the Uchiha for something one person did but still that's just messed up and it doesn't make him any better than them. Like why not just kill the people who are actually involved.

Shadow: I don't think Sasuke gives a shit especially after awakening the Sharingan's next stage, the Mangekyo Sharingan.

Zero: With the Mangekyo, Sasuke's genjutsu and other abilities not only increased and got stronger but he also has a ton of new powers.

Shadow: Like the Amaterasu, powerful black flames that can burn anything it touches and it's cast based on the user's sight, Itachi had these flames until he passed it down to Sasuke after he died. He can also manipulate the black flames and weaponize them the same way he does with Chidori.

Quick heads up: In the Naruto Jinraiden: The Day the Wolf Howled novel it was stated that Sasuke casted a genjutsu that could slow down time or possibly stop time. Giving him some form of time manipulation.

Zero: But with these eyes Sasuke can use the mighty Susanoo!

Shadow: This Susanoo is a giant avatar made of chakra that Sasuke uses for protection and he in deadlier fights.

Zero: But Sharingan 2.0 has a major downside.

Shadow: Right after using too much of it, this allows the user to go blind.

Zero: Yeah that kinda sucks.

Shadow: The only way around the blindness and achieve the Eternal Mangekyo Sharingan without the side effects of blindness is to ugh.... Pull out your own eyes than pull out another Uchiha's eyes and place them in your own eye sockets... that's what Sasuke did with Itachi's eyes...

Shadow and Zero:

[There should be a GIF or video here. Update the app now to see it.]

Zero: I think I'm gonna vomit....

Shadow: Okay... weird stuff aside Sasuke joined the Akatsuki to kill Danzo as his first step for vengeance against Konoha.

Zero: Despite how slightly unjustified he was, at least Sasuke gave Danzo the payback he deserved. Karma's a bitch.

Shadow: Finally after a faithful encounter with the Sage of Six Paths, Hagaromo, Sasuke not only obtained Six Paths chakra but also the Rinnegan.

Quick heads up: Considering Kabuto planted Hashirama cells in Sasuke's body that does mean he has some form of regeneration.

Zero: And those are some of the most deadliest eyes of all. The Rinnegan let's Sasuke absorb ninjutsu, summon animals, rip out souls, summon a daemonic statue, create cyborg arms, control gravity , and create giant ass meteors.

Shadow: Sasuke can also use the Amenotejikara by warping space and time he can switch places with another object or person.

Zero: Hell 15 years later Sasuke is able to create a portal which allows him to travel through specific dimensions.

Shadow: After meeting Itachi one last time who was brought back to life, Sasuke decided to finally carry on Itachi's wishes and protect the Lead village.

Zero: About damn time. So Sasuke joined the battlefield against all the heavy hitters.

Feats
Defeated 1,000 shinobi at once
Attacked the Five Kage Summit
Broke Itachi's Tsukuyomi
Put all 9 Tailed Beasts in Genjutsu in a glaze
Bested Danzo's genjutsu
Sliced through Madara's meteors
Created a moon that sealed Kaguya
Defeated Naruto Uzumaki, Orochimaru, Itachi Uchiha, Danzo Shimura, Obito Uchiha, Kaguya Otsutsuki

Shadow: Including Madara Uchiha, who Sasuke sliced in half this is the same Madara that survived an attack that cut the God Tree in half.

Zero: Hell he's easily compared to Naruto who can dodge a light speed laser at point blank range.

Shadow: Considering how most ninja can move at light speed we know that Naruto and Sasuke would have to be significantly faster thanks to the Six Paths power.

Zero: Hell the created an entire moon and undid the Infinite Tsukuyomi, the later of which takes around more than 2 yottatons to pull off.

Shadow: Despite saving the world, Sasuke and Naruto still had a score to settle.

Zero: Yeah a see here Sasuke wants to bring all the world's hatred on himself by killing the world leaders so he can repeat what Itachi did to him on a global scale. Honestly I can actually understand why he do it. But as usual Naruto will not stand by this and the 2 had their epic final battle.

Shadow: In the fight Sasuke absorbed all the Tailed Beast chakra into his Susanoo to become Indra Susanoo.

Zero: Oh yeah it's super powerful it can not only makes him WAY stronger than before but he can also use the strongest jutsu in his arsenal: Indra's Arrow.

Shadow: As it turns out Sasuke was the reincarnation of Indra Otsutsuki and the inheritor of his powerful chakra while Naruto was the reincarnation of Asura as these 2 brothers have fought for generations even after their deaths.

Zero: So basically Naruto and Sasuke were destined to fight even before they knew it. It's no wonder they could duel each other to a draw.

Weaknesses
Limited chakra
Rinnegan takes too much chakra
Hot headed
In his feelings and emotional
Eventually his Rinnegan

Shadow: Naruto eventually managed to talk Sasuke out of his quest and to find another way to bring peace to the ninja world. And so as part of his atonement for his sins Sasuke decides to spend the rest of his life protecting the village as a Shadow Hokage just like his brother before him.

Zero: So despite having a family with a daughter of his very own, Sasuke still can't shake off that edginess. Once an edgelord always an edgelord. But hey at least he gets to train Naruto's son Boruto.

Shadow: Despite Sasuke's rough start feeling alone after losing his clan and brother and following down the path of darkness, he grew up to be a better man and a better person one who is still on the path of redemption trying to atone for his past sins and to help best friend and brother figure in anyway he can.

Zero: He may have softened up and reformed himself as a person but he's still incredibly powerful so whatever you don't underestimate Sasuke Uchiha the Shadow Hokage of the Leaf Village.

Sasuke: At this moment I'm the strongest in the whole world and right here and now this will be the first step I take into the shadows.

Raiden Mei

Shadow: Despite growing up without a mother, kidnapped at one point but was rescued and had to placed under therapy and-

Zero: And growing up in a world where monsters such as the Honkai are on the lose in the world 24/7 creating disaster after disaster after disaster.

Shadow: Raiden Mei lived a pretty decent life.

Background
Full name: Raiden Mei
Age: 28
Height: 172cm
Weight: 50kg
Ex-Heiress of ME Corp
Captain of Squad 3 of Anti-Honkai Special Forces
Affiliation: Squad V (formerly), World Serpent (formerly)
Likes: Kiana Kaslana, Bronya Zaychik, her friends
Dislikes: Losing her friends, Elysia touching her horns
Is a master at cooking

Zero: Her family is the wealthy Raiden family and had a pretty loving father in the form of Ryoma.

Shadow: Ryoma is a businessman owner of a company called ME Corp, but despite that she cared and provided for his daughter, gave her some sword training, who would then go on to be part of a school for students from rich, powerful, connected, and wealthy families and as the heiress of the Raiden family, Mei would go to such a school where she was admired by both her students and teachers for her beauty, intelligence, and her as a prodigy allowing her to make lots and lots of friends and just like any other privileged student she was adored and admired by the entire school

Zero: Mei's life was amazing and was perfect. Until her father arrested for fraud and within the blink of an eye all the privileges and admiration she had disappeared in an instant.

Shadow: To make matters worse Ryoma was actually innocent.

Zero: Innocent in a sense that he was framed by this bitch Cocolia, who wanted to take over and needed Ryoma out of the way which ultimately led to his disappearance and probably dead later on.

Shadow: Mei's world was instantly shattered all of the people who were once there for her and who were once her friends all turned their back on her, leading to Mei becoming a victim of constant bullying, harassment, and resentment by both her teachers and students. Believing that their "friendship" and "adulation" were only reserved due to her family privileges and wealth and those had vanished after her father disappeared and possibly dead, leaving Mei all along to face a cruel and uncaring.

Zero: The bullying she suffered was so great that Mei ultimately heard a deep dark voice which turns out to be one be one of the most darkest powers out there.

Shadow: The Herrscher of Thunder. Infused with Honkai energy the Herrscher of Thunder uses the power of lightning to strike down terror on her foes. That was the voice in Mei's head and promised her to give her power to make the world suffer for her experiences, with literally nothing left to lose Mei chose to become a Herrscher at her own free will and embraced it's power.

Zero: And with this power she would go on to murder all of her classmates and teachers! Ever last one! She even took it a step further and ignited a Honkai eruption in Nagazora destroying the city and murdering millions of lives in the process. Damn in a single strike she became a mass murderer, and with the Herescher's power taking over Mei's body nobody can stop her.

Shadow: That is until she met a transfer student with white hair who was able to survive this Honkai eruption, Kiana Kaslana.

Zero: Thanks to her skills Kiana was able to battle Mei and defeated her in battle putting an end to the mass killing spree.

Shadow: But after turning back to normal Mei was horrified by the amount of damage she caused and the amount of lives she's taken, Mei decided to commit suicide by jumping to her death.

Zero: But thanks to her human conscience, Kiana actually saved her and managed to talk into living.

Shadow: Kiana sparked something in Mei like no person has before whereas previous people only liked her because of her heritage but for the first time Mei truly found a best friend in Kiana who had similar experiences of loneliness and Herrscher.

Zero: The two of them worked together to escape the now damaged Honkai inflected city alongside another girl named Bronya.

Shadow: But it didn't take long for them to be taken into custody by Murata Himeko, and enrolled in St. Freya High School, to tran to become the Valkyries an elite squad of members dedicated to stopping the Honkai all over the world.

Zero: And Mei's got the equipment to do it. Thanks to her various Valkyrie suits she has resistance to Honkai radiation on top of having increased stats.

Shadow: And thanks her training during childhood Mei is a master swordsman and along with her swords skills she has several incredible techniques.

Zero: Techniques such as creating a bunch of swords like she's Vergil from Devil May Cry, creating a couple of after images of herself, and the Time Fracture that let's her slow down time.

Shadow: Mei also has shown to have her signature abilities like lightning which she can use to cover her body, infuse it into her weapon form a large lightning sword, create lightning from her hand like a sword.

Zero: And being the prodigy that she is, Mei successfully passed her classes with flying colors thus putting her on the front lines against the Honkai.

Shadow: During her time at the St. Freya, Mei would eventually find happiness within a new family within the Valkyries after spending a majority of her life in utter darkness and loneliness. Unfortunately that didn't last.

Zero: Yeah one of the missions they were on went totally downhill and Mei got kidnapped prompting her friends to come her rescue which they did... but then Kiana got kidnapped by this bastard scientist Otto Apocalypse and reawakened the Herrscher of the Void, Sirin who would go on to steal the Gem of Conquest from her. Damn that's cold.

Shadow: Despite being a prodigy A+ student, Mei was always gets rescued and watches as her friends end up being the ones to rescue and not strong enough to return the favor.

Zero: Bronya turning off a chip that left her in a coma, Fu Hua getting shot only for her to use the last of her essence to guide others, Himeko tragically sacrificing herself to defeat Sirin to bring Kiana back, or it's Kiana herself sacrificing her life to stop a bomb from erupting an entire city and then to be kidnapped again by Durandal. No matter how hard she tries, Mei was always a damsel who needed to be rescued and protected by her friends and comrades and was too week to save them.

Shadow: But then her worst nightmares came true, due to having multiple Herrscher cores in her body and due to all the Honkai energy she took after disarming a bomb, Kiana only had 2 months left to live, this left Mei heartbroken and in a deep pit of darkness and despair, horrified that Kiana who saved her years ago has her days numbered.

Zero: And as if things weren't bad enough for poor Mei, Kiana didn't give a shit about how much time she had left to as she finds it her duty to save others.

Shadow: Despite Mei's plea, Kiana still went off anyway despite her condition to save Nagazora from a horrifying flood of Honkai. Ultimately Mei's efforts of saving Kiana ultimately ended in vain, and know she's forced to go on as Kiana, the girl who saved her from herself in Nagazora years ago, the girl that was her first true friend in a long time, the light that guided her out of the darkness, the girl who she fell in love with, and the girl who meant everything to her than the entire world was gone forever.

Zero: Or was she! Turns out there was still hope for Kiana to be saved which ironically came from the villains.

Shadow: Right, sometime earlier Mei had an encounter with a worldwide terrorist group organization known World Serpents and it's leader Kevin Kaslana, who was well aware the bond between Mei and Kiana.

Zero: Kevin actually says that there is a way to save Kiana and that would require for Mei to become a Herrscher of Thunder once again.

Shadow: In order to do this Mei would have to absorb enough Honkai energy that was in Nagazora to cause the Gem of Conquest that was stolen months prior will disappear from Kiana and reappear in Mei instead, once that happens the infection that was slowly killing Kiana would greatly be reduced. However Kevin told her that in return she would have to betray Kiana and join World Serpent.

Zero: Because we all know that making deals with the Devil don't come at a great price. Yeah Kevin needed Mei to compete World Serpent's plans for world domination.

Shadow: Nonetheless, Mei agreed to this offer without hesitation and absorbed enough Honkai energy and was once again the Herrscher of Thunder.

Herrscher forms
Flight
Advanced abilities
Gravity manipulation
Honkai energy reserves
Reality-alteration protection
Mind, soul, time, reality, and physical body
Herrscher of Thunder
Gem of Conquest
Better electric abilities
Can create thunderstorms
Teleportation
Can stun enemies at a far distance
Afterimage clones
Samurai hands
Samurai sword
Kurikara
Herrscher of Origin
Enhanced lighting abilities
Can stop time and shatter reality
Absolute Time Fracture
Can sunder time and channel energy

Zero: Herrschers can fly, manipulate gravity, can infuse Honkai energy within their attacks, and even have alternate reality protections like mind, soul, time, and everything else. Oh and they can erase you from existence.

Shadow: Mei was already skilled with lightning abilities but in her Herrscher those abilities increase by a mile, going as far as creating thunderstorms, teleportation, create multiple waves of lightning, and can even sting enemies even if she's not directly attacking them.

Zero: She also has those two big samurai hands with a sword and those two combined makes 2 deadly strikes.

Shadow: And as it turns out her father, Ryoma was actually the one who planted the Gem of Conquest in Mei in the first place.

Zero: Why the Hell would he plant one of the most dangerous items in the world in his own daughter.

Shadow: It was used to save her life, Mei's mother passed away but she also passed down her disease of cancer down to Mei that's why Ryoma planted the gem in her and gave her powers to help her beat cancer.

Zero: Well I guess if it works than it works. But hey anyways she can also summon this big red dragon in battle that can do shit like fire big blasts of lightning.

Shadow: Mei knew Kiana would not stand by her decision to join the World Serpent and after an emotional battle Mei was ultimately victorious against the person she cared about and as part of the deal she left to join World Serpent.

Zero: Because finding other ways to save Kiana instead joining a villain group responsible for the deaths of thousands of lives, and actively participating in their activities clearly doesn't exist in Mei's mind. You know if I had a nickel for every time a depressed lightning user deuteragonist desperate to get stronger and achieve their goals betraying the protagonist and ignoring better options rather than becoming a villain and joining a terrorist organization I'd have 2 nickels it's strange that it happened twice.

Shadow: Anyways now a member of World Serpent, Mei has continued to be up there among the elites.

Feats
Ignited the 2014 Honkai eruption in Nagazora
Battled Elysia to a draw
Saved Nagazora after reawakening
Mortality weakened Herrscher of Dominance puppets
Battled in near-absolute zero temperatures for a whole day
Battled Kevin's Diabolic test
Broke out of a dream of white space
Defeated Kiana Kaslana, Raven, Ana Schariac, Herrscher of Corruption, Kevin Kaslana

Zero: Herrschers are insane they are strong enough to tank supernovas, create solar systems and even have the power to battle foes who can rewrite all of reality itself.

Shadow: For context the Sea of Quanta, the Imaginary Tree, and the bubble universes all have infinite multiverses, infinite size timelines and. So obviously we're in for some BEYOND multiversal levels of power.

Zero: And Kiana was able to defeat Otto who had the power to do just that, and considering that Mei has been shown to be her equal in levels or power Mei should easily scale to this.

Shadow: During her time in World Serpent she ultimately started realizing how things could've been different and so after some time with the villains, Mei eventually left World Serpent and reunited with Kiana and reconciled her relationship with her and as part of her atonement she starts fighting on the side of good and has ultimately decided to respect Kiana's choices of sacrifice for now on.

Zero: And that's when she broke out of that dream like illusion of a false reality where And Hell she even encountered the original Herrscher Elysia it is there that she dueled her to a draw.

Shadow: After that she gained a new Herrscher form known as the Herrscher of Origin.

Zero: Origin's super damn OP it not only allows her to stop time but she can shatter reality while doing it.

Quick heads up: Consider Elysia once had the Origin it's likely that Mei could use most of her ultimate moves too.

Shadow: With the Origin's power Mei join Kiana, Bronya and the heroes to put an end to Kevin's plan once and for all.

Weaknesses
Honkai reserves are not infinite
Somewhat emotional
Was defeated by Durandal and Raven

Zero: Though sadly Kiana has to go to the moon until Earth is more than ready to handle her powers which means her and Mei are going to be separated once again.

Shadow: Though sadden by this Mei respected Kiana's decision knowing full well she will return.

Zero: She even became a captain of the for the Anti-Honkai Forces Special Forces in a world without any Honkai and trained a new Valkyrie in the process.

Shadow: Mei had a very troubled life losing both her parents, tormented by society, watching her friends sacrifice themselves for her, and joined a terrorist organization just to save the person closest to her. After reforming herself for her mistakes, Mei grew up to become a great hero of the world. After everything she went through Mei not only fights for Kiana and her friends but for the entire world and all of mankind.

Zero: She may have had her downsides but you would be foolish enough to try and to go toe to toe with Raiden Mei, the Empress of Lightning.

Mei: If rescuing you is a sin, I'll gladly be a sinner. Farewell, Kiana.

Verdict

(*Cues: Wiz & Boomstick - Brandon Yates-again*)

Shadow: Alright the combatants are set and we've run the data on all possibilities.

Zero: It's time for a DEATH BATTLE!!!!!!!!!!!!!!!!

Herrscher of Sharingan

(*Cues: Dangerous Gaze*)

[There should be a GIF or video here. Update the app now to see it.]

We see an abandoned town covered in trees and leaves with animals inhabiting the place on a cloudy day, as we see Raiden Mei in her Orochi Cuirass walking amongst the ruins of the town. But she stops after realizing she's not alone.

Mei: I know you're there come out and show yourself.

We then see a individual walking out of the shadows and on to the road this individual was Sasuke Uchiha standing by the building as Mei turns around to face him.

Sasuke: Oh I'm shaking in my boots especially looking at the Queen of Darkness. I suggest you state your intentions.

Mei ignores Sasuke and turns around and gives him warning.

Mei: It's none of your business, you don't need to know. Now turn back or-

Before Mei could finish her warning Sasuke immediately punches her in the back. As the Hidden Leaf ninja throws rapid punches the B-Rank Valkyrie attempts to retaliate only for her to be kicked in the chin and launched in the air as Sasuke uses his hands signs to form a jutsu.

Sasuke: Fire Style: Fire Ball Jutsu!

He launches a fireball at Mei who was barley able to block at it and land on her feet. The Sole Survivor of the Uchiha Clan Massacre attempts to strike the ex-heiress or the Raiden family but the later manages to dodge it and lands a punch towards Sasuke causing him to fall back a few feet away.

Sasuke: I'll end this quickly.

Sasuke draws his Sword of Kusunagi and charges at his opponent before Mei draw out her own sword to block his attack. The two swords clash at blinding speed with both sword users not landing a hit on the other and briefly knocked back they clashed again until finally the former member of the Akatsuki throws a punch at the former member of World Serpent. He then throws his sword, uses Chidori, and activates his Sharingan and Rinnegan. Mei falls back and gets on her feet only to barely dodge her opponent's sword thrown at him. Sasuke then switches places with the sword appearing behind Mei and lands a strike on her knocking her down hill.

Once the camera zooms back into the fight, Mei has crashed to a nearby building as she attempts to recover from Sasuke's assault.

Mei: You... bastard.

She then narrowly dodges Sasuke's sword that's thrown at her again only for Sasuke himself to once again use the Amenotejikara to switch places with the blade and strike her again with Chidori causing her to fall on her knees. Sasuke regains his weapon and taunts his fallen enemy.

Sasuke: Now that's battling with your eyes. Don't ever mock the Uchiha.

With a chuckle Sasuke activates the Mangekyo Sharingan, before Mei could react was coated in the black flames of Amaterasu causing her to scream in immense pain, as she starts losing consciousness she desperately attempts to reach out to her opponent who the covers her in more black flames as the Valkyrie passes out. Mei wakes up in a grassland sunny area as she gets up to observe her surroundings.

Mei: What's going on? Am I dead?

As she tries to wonder what happened to her she hears voices. When Mei turns around she sees Kiana armed with her guns.

Mei: Kiana..?

Kiana without word fires several bullets at Mei greatly wounded her soon, she would find all of her friends shooting at her, Mei confused as she doesn't understand why they would do this. As she agonizes in pain Kiana points a gun at her head. While she was scared and whimpering at first she calms down and finally realizes that she's under Sasuke's genjutsu as she laughs.

Mei: I'll have to give you credit for placing me under some type of illusion but if you think that will stop me you're dead wrong.

Mei pulls put her sword and slashes away all of the imposters disguised as her friends as the genjutsu breaks and the screen goes black.

Meanwhile at the same time back in reality Sasuke observes the burning Mei still unconscious.

Sasuke: So that's it? Well that was disappointing I thought you were a bigger threat but it seems like that's not the case.

Sasuke puts his sword away and starts walking away while monologuing his victory.

Sasuke: Well in any case even if you break out of the genjutsu you'll still be dead due to the enormous amounts of the Amaterasu so looks like it's over.

When Sasuke is finished talking he suddenly unexpectedly hears a familiar voice.

Mei: Is this the death you had imagined for me?

Sasuke is shocked to hear this as he turns around. The music starts up again where lightning from the sky strikes down at Mei's supposedly dead body. Mei herself than gets up still covered in black flames, much to Sasuke's shock.

Sasuke: H-how... Who or what are you?

Mei charges up her power washing away all the black flames and is not only healed but has transformed into the Herrscher of Thunder. The Herrscher then answers the Uchiha's question.

Mei: Pathetic fool. I'm the lightning empress. Never underestimate the Uchiha huh? That's a good advice now it's my turn to give you mine! Don't underestimate the Herrscher of Thunder!

Mei does a huge sword slash of Honkai and lightning energy onto Sasuke, who partially activates Susanoo to block the attack. However, the attack overwhelms Sasuke's defenses and knocks him in the air.

Sasuke: Damn you!

Sasuke is forced to unleash the Perfect Susanoo completely pissed off. Mei then does a hand taunt telling her opponent to "come on" as she dodges an incoming sword swing at her. Mei runs back and has another trick up her sleeve.

Mei: Come Kurikara!

She summons Kurikara and jumps on her back and flies towards the Susanoo it will be then that the battle is taken to the sky as Naruto and Kiana's clash their ultimate swords. During the struggle Sasuke would realize he needs a better plan to beat Mei.

Sasuke: (thinking) She's getting tougher... I need more time!

The Susanoo wins the struggle and uses his own summoning.

Sasuke: Kirin, come!

Sasuke summons his electrical dragon from the sky surprising his foe. Sasuke would then send Kirin to strike down Mei and Kurikara causing it to explode. The reincarnation of Indra has another trick up his sleeve.

Sasuke: Chibaku Tensei!

Doesn't a parts of the earth start to surround Mei and her dragon as the rocks trap the Herrscher in a small sized meteor. As Sasuke activates Onyx Chidori with Six Paths powers but before he could land a strike Mei breaks out of the meteor now transformed into the Herrscher of Origin. Mei stops time and does severe slashes by the time, time resumes Sasuke's Susanoo would be destroyed as Mei grabs him in a choke hold and attempts to give Sasuke a chance to give up.

Mei: This is your last chance, Uchiha, leave while you still can't don't make me repeat myself a third time.

However, Sasuke chuckles at Mei's warning.

Sasuke: You have no idea Herrscher I've been right behind you this entire time.

The Sasuke that Mei was holding was revealed to be a Shadow Clone much to Mei surprise as she looks behind her and sees the real Sasuke was in his Indra Susanoo form much to Mei's surprise. We cut to a brief flashback where it reveals that Sasuke created a Shadow Clone after launching Kirin which hit Mei, while the clone deals distracts Mei, Sasuke leaps out of the Susanoo summons all the 9 Tailed Beast place them under genjutsu traps them and absorbs their chakra.

We cut back to the present the Team 7 member charges up his strongest attack Indra's Arrow.

Sasuke: Take this!

As he fires the arrow the Squad V member than unleashes an attack of huge blast of Honkai energy combined with Kurikara's lightning blast as all the attacks clash it creates a lightning explosion sending both of the deuteragonists flying backwards.

When the dust settles, both warriors fall to the ground unconscious and covered in scars having used up their strongest attacks and lay unconscious to the ground. Sasuke wakes up first as he takes a moment to catch his breath. Mei back into her Orochi Cuirass soon wakes up as well.

Sasuke: I'll put you to rest now.

Sasuke decides to use the remainder of his strength into his blade with the combination of Amaterasu, Chidori, Onyx Chidori, Chidori Sharp Spear to increase the size of the lightning blade, he then uses Chidori Stream to cover his entire body with lightning and covers the first half of the area. Mei loos and and notices Sasuke as he activates the Mangekyo Sharingan and Rinnegan to reveal the Susanoo infused with Amaterasu and Chidori Sharp Spear and Chidori Stream. With this Sasuke leaps for leading a battle cry.

Mei: Then I shall do the same to you.

Mei responds by covering her body with lightning as the lightning strikes her and increases the size of her lightning sword and combines it with Honkai energy. The two lightning users charge at each other while yelling at the top of their lungs and with all their might unleash one last sword swing. The result of this is a electric shockwave that went through across town.

When the dust settles Sasuke's Susanoo, Amaterasu, and Chidori disappears and the Sharingan and Rinnegan eyes deactivates as he coughs out blood. Mei's lightning infused Honkai energy would be disappear as well as she mortally and scared wounded from nearly top to body as she coughs out blood and falls on her knee due to being slashed 8 times. Sasuke would notice his blade break in to four pieces before his whole body falls apart into pieces from his head arms, legs and torso shortly after, due to six sword slashes. Having won the battle, Mei gets back up on her feet.

Mei: It's over.

As she says this she looks back at the remains of her fallen opponent.

Mei: But bear this in mind I asked you not to try and attack me yet you did it anyway I also told you not to make me repeat myself a third time.

After taking a deep breath Miss Raiden pays her respects to the now deceased last Uchiha and prepares to leave before looking back one last time.

Mei: Sayonara, Uchiha.

Mei then proceeds to walking away leaving Sasuke's remains behind.

KO!

Results

(*Cues: Dangerous Gaze again*)

Zero: Now that's what I call a shocking way to end the fight.

Shadow: Sasuke may have been the more intelligent, experienced, and better training of the two but Mei simply held the advantage in almost every other category.

Zero: Sasuke may have been able to hold his own against planetary foes like Madara, Kaguya, and other Otsutsuki, but Herrschers like Sirin can survive supernovas and even create solar systems.

Shadow: And while it was stated that Kaguya's dimensions have stars in it, there's some inconsistencies within it because there's no reason to think that the dimensions are even close to being that size.

Zero: Even if it was that big that's still nothing compared to the infinite sized cosmology of the Honkai verse. Hell Mei is even a lot faster than Sasuke as Herrschers have performed dozens of insane feats that even we can't calculate.

Shadow: Even if we equalized their stats and make this fight much more even a closer Sasuke still couldn't find any meaningful way as Mei actually has counters to almost everything Sasuke can throw at her.

Zero: Outside of the obvious lighting abilities, like how Mei broke out of that white dream space full of fantasies and false realities suggests that Sasuke's genjutsu powers wouldn't work on her.

Shadow: And while Sasuke has battle and worked around foes who have resisted his genjutsu before like Danzo, it's still most likely wouldn't make much of a difference here.

Zero: Too be fair Sasuke could just use genjutsu to restrain her or enter her consciousness or read minds and find out the secrets of her power like the Herrscher gem and try and take it away from here.

Shadow: Even if Sasuke could so that, Mei has other abilities to counter that like her time manipulation abilities.

Quick heads up: While it was stated in the novel that Sasuke's genjutsu slowed down time it could just be a topical genjutsu, even if it was outright time manipulation Mei's resistance's and her own time abilities counter it entirely.

Zero: As for his other abilities where Sasuke can manipulate gravity, Herrschers can do that too also he can't rip her soul out because not only would he have to tag her but once again Herrschers have resistance to soul manipulation powers.

Quick heads up: While Sasuke having  Hashirama cells does give him some form of a healing factor there's no evidence that he could heal with half his body vaporized like Ten Tails Madara.

Shadow: It's also worth noting that while similar, Honkai energy is not Chakra so therefore Sasuke's abilities to absorb ninjutsu would not work on Mei.

Zero: Even if he could absorb powers outside of chakra, Mei could just blitz him before he could do any lasting damage.

Shadow: While Sasuke does have some powers that can Mei can't counter like his fire abilities, meteors, and Susanoo it's still not enough to compete with Mei in power.

Zero: Plus unlike Sasuke, Mei doesn't have to worry about losing as much Honkai energy as she shown greater stamina than he has. So regardless of scenarios even if we equalized their stats Sasuke will have a hard time trying to land a fatal blow. Plus Mei could theoretically just erase Sasuke from existence anyways so yeah.

Shadow: Both Sasuke and Mei are among the best of the best in their respective worlds with great compelling stories but like most MUs it all comes down to who will land the killing blow first. Sasuke put up a good fight and wasn't going down so easily, but Mei's raw power, speed, and incredible Herrscher abilities were just too much for the lone Uchiha.

Zero: Sasuke was Herrscher he had it but shocking as it Mei be, he was a Sharinganer for the last time.

Shadow: The winner is Raiden Mei.
