RWBY vs DC, two psychopathic duos goes out in a murderous battle of the killer couples.

<Cue: Invader Theme>

Toomi: Have you ever heard of the infamous Bonnie and Clyde? Well, these two are the best fictional examples of a duo of death.

Megumi: And their extremely pyschopathic.

Toomi: Like Roman Torchwick and Neopolitan, former members of Cinder's Faction and the White Fang,

Megumi: And The Joker and Harley Quinn, Gotham's pyscopathic clowns of crime. She's Sachi-san, Toomi-san and I'm Megumi-san

Toomi: Due to a request from MLPFan001, we will not be the ones doing the analysis but rather, Yang and Blake would be the ones doing it.

Sachi: But regardless, it's our job to analyse their weapons, armour and skills to find out who would win a Death Battle

Roman Torchwick and Neopolitan slits into What if Battles

<Cue: Bonnie & Clyde by Jay Z feat Beyonce>

Yang: So what are we doing here again Blake?

Blake: I don't know, but a bunch of girls says we need to talk about those two slimeballs Roman Torchwick and Neopolitan.

Yang: Ooh! I hate her!

Blake: Well too bad, we've got to do it anyway.

Yang: Fine. Well, considering all the previous chapters of us, we won't waste any time talking about our school and our world.

Blake: Instead, we will start off by talking about Roman Torchwick, Vale's Most Wanted Criminal.

<Shows footages of people cowering in fear as Roman and his henchmen walks along the streets.>

Blake: Roman Torchwick is a professional criminal operating in the city of Vale, and despite his small range of business, he is more than a match for most amateur huntsmen.

Yang: That is until my little sister Ruby here took him down.

Blake: Well, if truth to be told, Well Cinder Fall and the group she was working for definitely chose the right criminal to carry out their plans. While he isn't exactly subtle based on how he is dressed and has trouble dealing with super-powered teens, Roman has managed to steal most of the Dust in Vale without getting caught and carried out quite a few of Cinders schemes with varying degrees of success.

Yang: And he isn't far without this one particular person I so much hate...ugh! Neopolitan.

<Shows footages of Neopolitan standing at the blimp.>

Blake: Neopolitan was Roman Torchwick's closest associate, often accompanying him on his most important missions.

Yang: And if I had to be honest, she defeated me after a long battle against Grimms for the entire day and she could have killed me if mommy dearest hasn't interfered.

Blake: And during the 40th Annual Vytal Festival Tournament, Neo disguised herself, and competed as part of a team that also included Cinder Fall, Emerald Sustrai and Mercury Black. 

Yang: And long story short, she rescued him.

Blake: Later, Neo rescued Roman from his imprisonment aboard an Atlesian Airship, and assisted him in downloading a computer virus into the AK-200 soldiers' system.

Yang: And when Ruby arrived on the ship, both Roman and Neo team up, almost defeating her until Ruby opened her parasoul, sending her flying off into the air.

Blake: And as for Roman, well...

<Shows footages of a Grimm eating Roman, instantly killing him>

Yang: Damn. Ain't it ironic that his last words were lie, steal, cheat and survive?

Blake: But luckily for Neo herself, she survived, swearing revenge on everyone who caused Roman's death, resulting in her teaming up with Cinder to hunt down Ruby. But no worries, we will defeat them.

Yang: If any of you readers paid attention to our many RWBY fights back then, you will know that like everyone else, both Roman and Neo possesses something known as an aura, a manifestation of one's soul or life force. They can use those to heal injuries and create small energy shields to shield themselves from attacks.

Blake: Being a master criminal, Roman is an expert thief, skilled at pickpocketing and robbing others, even able to rob a massive shipment of Dust.

Yang: And like most people, he has a weapon. Meet Melodic Cudgel. It may look like a cane but it has a base of a shotgun, pretty handy for both melee and long range attacks.

Blake: And Neo has a semblance where she can create illusions.  These illusions act as Neo dictates, and exist until they are struck or she dispels them. She can make the illusion of just herself, or herself and at least one other person.

Yang:  In combat, Neo often creates an illusion of herself, and then while her opponent is focused on the illusion, she moves up and attacks them from a blind spot.

Blake: Alternatively, Neo can also cast an illusion on herself, making her appear different – different eye and hair color, different clothing, you know the rest.

Yang: After a near death encounter with Neo and Roman, me and Ruby can definitely agree that both Roman and Neo are really deadly fighters, with the two able to overpower by sister Ruby. And yes, Neo defeated me, please, I need no reminder.

Blake: Roman has moved fast enough to dodge a point blank shotgun shot from Jingu Bang and Ruyi Bang, held his own against me and Sun Wukong and even convinced some Faunus to join him and his White Fang.

Yang: Which is ironic since according to this, he hates the Faunus.

Blake: As for Neo, she was able to hold her own against Cinder, beat Yang in combat and even rescued Roman before helping him download a computer virus into the AK-200 soldiers' system.

<Shows footages of Neo fighting on par with Cinder>

Feats

Roman is capable of holding Off Sun Wukong and Blake Belladonna by himself

Roman has dodged and blocked a Barrage of Point-Blank Shotgun blasts from Ruyi Bang and Jingu Bang

Roman as able to track Blake Belladonna in a fight despite the fact that she was using her Semblance

Roman and Neopolitan was able to easily best Ruby Rose

Despite being Human and having been shown clear hate and malice as well as shown his dislike for them, Roman was capable of convincing multiple Faunus during a White Fang Rally to side with him and the White Fang

Despite not having discovered his Semblance, was still capable of taking on Blake, Ruby, and Sun in their respective fights

Neopolitan easily defeated Yang

Neopolitan casually dodged blows and gunshots from Yang

Neopolitan took over an entire Atlessian ship by herself

Neopolitan acted as a Fourth Member of Team Cinder during the Vale Festival

Neopolitan helped Roman escape

Neopolitan and Roman managed to infect the Atlesian Knights with a computer virus

Neopolitan held her own against Cinder Fall

Yang: But luckily for us, those two are not really invincible at all. Like everyone else, their aura is finite and shockingly, Roman has no semblance. Like at all.

Blake: Roman is extremely overconfident and really tends to underestimate his opponents which does bring a massive disadvantage to him in battle.

Yang: And he got eaten by a Grimm. Nobody can ever forget that.

Weakness

Both Neo and Roman's aura are finite

Roman has not discovered his semblance

Roman can be taken by surprise and unable to adapt properly to certain attacks

Roman is overconfident and tends to underestimate his opponents.

Roman got eaten by a Grimm

Neo is psychotic and sadistic

Neo will flee if she finds herself outmatched

Neo was outsmarted by Ruby

Neo is scared of Raven Branwen

Blake: And as for Neo, she tends to avoid fights she know she can't win and her psychotic personality means she will go all out to kill her opponents, which results in her letting her own guard down.

Yang: But considering how dangerous those two are, we can see why Cinder would recruit them into her faction.

Roman: You're asking the wrong questions Red! It's not what I have to gain, it's that I can't afford to lose!

Joker and Harley cackles into What if Battles

<Cue: Heathens by Twenty One Pilots>

Blake: In the infamous city known as Gotham, criminals of all kinds always seems to rise from all places, causing mayhem.

Yang: Whether it be a short stubby bird man, a man with a burnt face or a smokin' hot cat woman, none of them compares to the criminal known as the Joker.

Joker: Tada! It's a magical!

Blake: Well, there's not much we can say about this Joker considering how the scripts don't really have much of a backstory of him. But what we do know is that Joker was a regular man who fell into some chemicals in the Ace Chemical Plant, transforming him into the Gotham's Prince of Crime.

Yang: And truth to be told, the Joker really lived up to his reputation, that is until a certain man in a batsuit defeated him, locking him away in Arkham Asylum.

Blake: It was there when he met a young woman named Harleen Quinzel, a career-oriented psychiatrist assigned to him.

Yang: Through regular therapy sessions with the Joker giving her various versions of his origin story, the inexperienced Harleen fell hopelessly in love with him.

Blake: Ironically losing her own sanity while becoming an accomplice in his escape, she felt the Joker "saved" her from her boring life as she adopted the alias Harley Quinn

Harley Quinn: Well, everyone on my show's gonna have fun alright? We'll bash their fucking heads in!

Blake: While initially a flunky who wanted to win Joker's approval as go on criminal sprees in Gotham, using her sexuality and her playful personality to achieve her goals or to entertain herself at the expense of others, Harley became a villain in her own right and was eventually recruited by the Suicide Squad program.

Yang: Yeah, cause things didn't really go well between those two psychos anyway.

Blake: Joker uses a wide variety of instruments to exact his homicides, a genius at criminal activities and being a step ahead of the law with acting skills and a sufficient expertise in chemistry to be make deadly weapons based on party-gag items.

Yang: He is also shown to be a skilled, fearless, and unpredictable fighter who is a strong hand-to-hand combatant.

Blake: But Joker isn't just skilled in hand to hand. He carries all sorts of weapons, ranging from handguns, tommyguns, poker cards as deadly as shurikens, Joy Buzzers, Acid Flowers and his trademark Joker Venom.

<Shows footages of Joker unleashing his Joker Venom into the studio, affecting the entire audience>

Yang: Wonder why the venom doesn't affect him? Well, considering how often he had been using it, repeated exposure somehow makes the Joker immune to his own venom.

Yang: And about her backstory, yes. She is a doctor and a surgeon.

Blake: Her repeated exposure to Joker's Joker Venom and Poison Ivy's serum has affected her physique to the point not only did she became more insane but like the Joker, she also became immune to their effects as well.

Yang: Like Joker she uses trick weapons primarily, but Harley is willing to use oversized or blunt melee weapons as well. One such weapon is her trademark mallet.

Blake: She also carries a lot more weapons, including revolvers, baseball bats, chainsaws, batons, boxing glove guns, snare traps and even a Jack n the Box bombs.

Blake: And Harley has even bested the likes of Poison Ivy and Swamp Thing, and once even ripped the head of Lobo off his own body.

Yang: And if I remember, that guy is strong enough to take on Superman.

Blake: And speaking of Superman, Harley even once defeated a depowered Superman during a boxing match.

Blake: Alright, the combatants are set, let's end this debate once and for all.

Yang: Ladies and gentlemen, boys and girls, freaks and misfits of all ages, it's time for a Death Battle!

Fight

Bank

It is midnight in the dark bleak city of Gotham.

A black cat scurries across the streets, dashing past a coupled of uniform guards standing at the entrance.

A guard ignites a cigarette with his lighter and he asks his companion.

Jake: Fancy a fag Will?

Will: Don't mind if I do Jake.

As the guard takes a cigarette out of the box, right at that moment, a car drove forward at what seems like the speed of a freighter train, slamming right into the two guards before hitting the main entrance.

BAM!!!

As glass rains from the shattered door, the engines of a coloured car purrs as a figure cladded in green and purple and another cladded in red and black steps out of the vehicle, grinning maniacally at the safe in front of them.

They are no other than the nefarious Joker and Harley Quinn, the clown criminals of crime.

Joker ushers his girlfriend forward, speaking out.

Joker: C'mon Harley. Let's make this quick before Bats comes and ruin all the fun.

Harley: Hee hee, you got it Mister J!

Harley skips forward, slamming her baseball bat right into the lock, instantly destroying it.

BUSH!!!

The door slowly slides open and both Harley and Joker pulls it open, finding themselves staring right into a massive mountain of gold.

Joker cackles out in malicious delight.

Joker: Ah ha ha ha! We're gonna be rich Harley!

However, right at that moment, a loud massive explosion booms from the roof top, sending chunks of debris flying everywhere.

KABOOM!!!

Joker: ARGHHHHH!!!

Harley: AAAHHHHHH!!!

As both Joker and Harley staggers back, two figures lands foot first in front of them.

One is a tall male cladded in a white and purple suit and the other is a short female cladded in pink and brown.

They are no other than the master criminals of Vale, Roman Torchwick and Neopolitan.

Joker looks up, questioning the two.

Joker: Huh? Who are you? You're with the bat?

Neo simply shrugs in confusion as Roman asks.

Roman: What Bat?

Harley: Never mind that, we're here for the gold.

However, Roman raises his hand up, chuckling at the two.

Roman: Heh heh heh! I'm afraid not you two. You see, we're taking the gold so please, step aside.

Upon hearing that, Joker bursts out in a maniacal fit of laughter.

Joker: Ah ha ha ha ha ha!

Startled by the Joker's sudden outburst, Neo points her parasoul at him just as Roman questions him.

Roman: What's so funny?!

Joker wipes a tear from his eye as he said.

Joker: You know, you're right. You should take the gold.

Roman's mouth twists into a smile and he smirks.

Roman: Heh! Glad we see eye to eye.

Joker: Indeed...

Before Roman could even react, Joker pulls out a crowbar, swinging it right across Roman's face.

BAM!!!

Roman: ARGHHHH!!!

As Roman staggers back, Joker holds up his crowbar, declaring to Harley.

Joker: Harley dear. Let's dance.

Harley: Hee hee! Can't wait!

Announcer: Fight!

<Cue: Romeo and Juliet vs Bonnie and Clyde instrumental by ERB>

Joker and Harley sprints forward, the couple swinging their weapons at the pair.

Neo somersaults over Harley's head, casually dodging a swing from Harley's bat.

Just as Harley swings it back, Neo simply raises her parasol up, blocking a single blow from her.

Clak!

Neo the throws her foot up, striking Harley in the jaw.

WHAM!!!

Harley: Ow!

Neo spins around before swinging her Parasol across, easily disarming Harley.

Pak!

Harley: Ow!

Harley glares at Neo, growling at her.

Harley: Oh! You're so toast!

Harley pulls out a revolver, pointing it right at Neo before opening fire at her.

BANG!!! BANG!!! BANG!!!

Neo somersaults across the bank, dodging the massive rounds of gunfire from her opponent.

Meanwhile, Roman raises his Melodic Cudgel, shielding himself as the Joker strikes at him with multiple blows from his crowbar.

CLANG!!! CLANG!!! CLANG!!!

Roman points Melodic Cudgel, opening fire at the Clown Prince of Crime.

BANG!!!

Joker narrowingly dodges the bullet before slamming his forehead right into Roman.

BAM!!!

Roman: ARGHHHHH!!!

Joker spun around, pulling out a handgun before opening fire at his opponent.

BANG!!! BANG!!! BANG!!!

Roman jumps across the room, dodging the hail of gunfire from his opponent before pointing Melodic Cudgel at the Joker, opening fire at him.

BANG!!!

CLANK!!!

Joker: ARGHHHHH!!!

The Joker screams out, clutching his hand as the gun falls onto the floor.

Roman throws Melodic Cudgel across, striking it right into the Joker.

TWAP!!!

Joker: ARGHHHH!!!

Roman the grabs Melodic Cudgel, swinging it right at the Joker.

WHAM!!! BAM!!! POW!!!

As the Joker staggers back, Roman points Melodic Cudgel at the Joker, saying to him.

Roman: Give up!

The Joker pulls out a pistol, pointing it right at Roman.

Joker: Not yet.

BANG!!!

The gun open fires, only revealing a small flag protruding out of the nozzle.

As Roman stares at the Joker in confusion, the Joker said to himself.

Joker: Whoops. Well, I guess I gotta...whoops!

SPLSSSHHH!!

Right at that moment, the flower on his shirt began splashing green acidic liquid onto Roman, causing him to scream out in pain.

Roman: ARGHHHH!!!

Joker: Ha!

Joker then grabs a pie and he slams it right into Roman's face.

SPLAT!!!

And right at that exact moment, the pie went off in a fiery explosion.

KABOOM!!!

Roman: AHHHHHHH!!!

Roman screams out in agony just as he was sent flying from the explosion.

Joker: Neh heh heh heh!

Joker chuckles out as he pulls out a tommy gun, pointing it at Roman.

Joker: Well well little man. Say hello to my little friend!

BANG!!! BANG!!! BANG!!!

Roman: Shit!

Roman curses out as he lunges across the room, running as the Joker opens fire across the room.

At the exact moment, Harley steps back just as the Joker unleashes a hail of gunfire across, forcing Neo to jump back.

Joker: Ah ha ha ha ha ha!

As the Joker laughs out in delight, he turns his head, watching just as Roman sprints across the walls of the room.

Joker pulls out a denture and he throws it upwards, only for Roman to swing his Melodic Cudgel across, deflecting the projectile.

Pak!

At the same time, Harley pulls out her mallet, swinging it right at Neo, striking right into her.

WHAM!!!

Harley: Ha!

Harley then pulls out her Jack in the Box bomb and she throws it at Neo.

Neo looks down just as the bomb went off in a fiery explosion.

KABOOM!!!

As flaming pieces of gold rain across the room, Harley chuckles out in delight.

Harley: Puddin look! I made it rain!

However, right at that moment, something sprints across Harley at supernatural speed, striking right across her face.

WHAM!!!

Harley: ARGHHHH!!!

Harley turns around, her eyes widens upon laying eyes at the figure in front of her.

Standing in front of Harley stood Neopolitan, completely unharmed.

Harley: What?! But how?!

Harley stutters out in shock, staring back before looking back at Neo.

Neo simply shrugs, the gesture only angering Harley even further.

Harley: Alright! That's it!

Harley then pulls out a massive chainsaw, igniting it's engines.

VRRROOOMMM!!!

Harley: Mama's gonna mince ya tonight!

Harley lunges forward, swinging her chainsaw wildly at Neo.

Neo jumps back and forth, dodging swing by swing as Harley closes in onto her.

At the same time, Joker backs away just as Roman lands footfirst onto the ground.

Thud!

Joker tosses his tommy gun aside, raising his fist upwards.

However, Roman picks up a gold bar and he thrusts it backwards, striking the Joker right in the head.

Pok!

Joker: ARGHHHH!!!

Roman spun Melodic Cudgel around before swinging it across, striking right into the Joker.

WHAM!!!

Joker: ARGHHHHH!!!

As the Joker falls backfirst onto his car, Roman pins his cane onto the Joker's neck, questioning him maliciously.

Roman: Any last words?

Joker: Yeah. #GrumpyBat

PSSSHHH!!!

A wisp of green gas began emitting from Joker's flower, hitting Roman right in the face.

Roman: ARGHHHHH!!!

Upon hearing his scream, Neo turns around, prompting Harley to throw her leg outwards, striking her in the back with a single kick.

WHAM!!!

As Neo drops onto the floor, Roman continues staggering across the room, his screams slowly turns into agonized laughter.

Roman: Huh huh! Heh heh! Ha ha ha ha!

Joker: AH HA HA HA HA!!!

Joker cackles out in delight as Roman continues laughing out before collapsing right onto the floor.

THUMP!!!

Joker shrugs and he kicks Roman's dead body, declaring out.

Joker: Deep down you know this is funny

KO!

As Neo raises up her head, her eyes widens in horror upon laying eyes on Roman's dead body.

Harley stood over Neo, holding up a chainsaw and she cruelly gloats the dumbstruck assassin.

Harley: Ha ha! Your boyfriend couldn't kill Mister J! And you're next lady!

VRRROMMMM!!!

Fueled with anger, Neo spun around, throwing her leg right into Harley's face.

WHAM!!!

Harley: ARGHHHHH!!!

Harley turns around, throwing her chainsaw right onto Neo.

Neo ducks underneath the projectile, closing in right into Harley before slamming the sharp tip of her parasol right into her gut.

SHOK!!!

Harley: Cough!

Harley coughs out in agony, her body fell limp as Neo looks up, her eyes glistering with hatred.

Standing across the two, the Joker screams out.

Joker: Harley! No!

SHOK!!!

Neo forcefully tugs her parasol out of Harley's stomach, watching just as the clown falls flat onto the floor.

As Harley felt her life slowly fading away, Neo stood over her, narrowing her eyes  as she raises up her leg, slamming her foot down onto Harley.

THUMP!!!

KO!

As Neo pulls her leg away from a dead Harley, she turns her head, directing her attention now to the Joker.

Joker walks towards her, offering out his hand.

Joker: You know, you lost a man. I just lost my girl. So why not let's call it even?

Neo angrily slaps Joker's hand away, causing the Clown Prince of Crime's face to fall.

Joker: Oh what the heck!

Joker throws a punch, forcing Neo back.

As Neo spun around, right at that exact moment, Joker slams his palm right into her back.

Before Neo could even react, she could feel a massive surge of electricity crackling across her body.

BZZSSSTTTTT!!!

Joker then pulls out a knife and he swings it across, cutting Neo across the face.

SLASH!!!

As Neo staggers backwards, Joker steps towards her, speaking out.

Joker: You know, I almost feel sorry for you. Such a nice young little girl. Maybe Batsy will want you with his little Robin of his.

Angered, Neo swings her parasol, only for Joker to swerve his body to the side, slamming his knife right into her back.

SHOK!!!

As Neo grits her teeth in pain, Joker picks up Harley's bat and he mockingly jeers.

Joker: Come on! Even Robin's put up a better fight than you!

WHAM!!!

Joker swings the bat across, sending Neo flying with a single swing.

CRASH!!!

As Neo crashes backfirst into the wall, Joker steps forward, saying to her.

Joker: Well well, looks like another one bites the dust.

Joker pulls out his handgun and he opens fire.

BANG!!!

As everything around the Joker fell silent, the Clown Prince of Crime suddenly felt a strong eruption of sharp agony piercing right through his chest.

SHOK!!!

Joker: ARGHHHHH!!!

Joker stumbles forward, coughing out blood as the dead Neo's body disappears, shocking him.

Joker: Huh?

The Joker spun around, his eyes widens in shock as he found Neo sitting cross legged on top of a pile of gold bars.

Joker: But how?

Neo simply gives him a smug look, angering the Joker even further.

Joker: RAAAHHHH!!! Enough monkeying around!

Joker pulls out several poker cards, throwing them across the air, Neo lunges from the pile of gold bars, her parasol spinning across the air, deflecting the cards with ease.

CLANG!!! CLANG!!! CLANG!!!

Before Joker could even react, Neo slashes her parasol's blade across his torso, cutting right through him.

SLASH!!!

Joker: ARGHHHHHH!!!

Neo then turns around, holding up the Joker just as another Neo lunges forward, slamming her parasol straight into his chest.

SHOK!!!

Drip! Drip!

Blood drips from the Joker's open wound as the Clown Prince of Crime's body fell limp, dropping onto the floor.

The Neo clone vanishes immediately as Neo picks up a bag, tossing several gold bars into the bag before jumping out of the vault, leaving the corpses lying all over the bloodied floor.

Neo steps outside, a smile forming from her mouth as FrostWing flies down, greeting her.

FrostWing: Hey Neo. Well, looks like you just gone robbing again huh? How's Roman?

Neo looks down, causing it to suddenly dawn on him.

FrostWing: Oh. Sorry.

Neo then jumps up, sitting on top of FrostWing's arms just as the Saiyan and God of Destruction Hybrid said.

FrostWing: Alright. Let's go home.

FrostWing then carries Neo up into the night sky just as Batman arrives at the scene of the crime, his eyes widens in shock at the mess within the vault.

KO!

<Cue: New Earth by Bruce Falconer>

Megumi: Damn. This is some robbery!

Toomi: The Joker and Harley are extremely unpredictable but Neo and Roman are a complete different level of combatants

Sachi: Indeed, Roman and Neo's ability to keep up with people like Blake and Ruby proves they had the speed advantage over Joker and Harley, those two who has trouble dealing with people as swift as Man Bat.

Megumi: But Joker and Harley's high pain tolerance and intelligence gave them the major advantage, with Joker and Harley being able to take a massive amount of punishment from the two and Joker was able to use his Joker Venom to finish off Roman.

Toomi: Which leaves Neo against Harley. While the two are surprisingly agile and acrobatic, Neo's intelligence and skills to hold her own against an injured Cinder proves she had what it takes to take down Harley.

Sachi: But the real fight begins when Joker and Neo faces off each other. With Joker's combat skills and unpredictability and Neo's agility and illusion, who's to say the fight couldn't have gone both ways.

Toomi: Truth to be told, this was a surprising close call except for one thing. Neo's intelligience. 

Megumi: Indeed, considering how Neo has observed how Joker killed Roman in the fight, Neo would most likely use the same kind of intelligence to send her illusions as a decoil to lure Joker's attention away, thus finishing him.

Toomi: With Neo's cautiousness, and her illusions being able to fool Joker into taking his eyes off her, this is what gave Neo the win over the Joker.

Megumi: That's what Joker and Harley got for Clowning around

Sachi: The winners are Roman and Neopolitan.

Roman: Now, I'll be the first to admit, humans... are the worst. Case in point.

Toomi: Hey guys, thank you so much for checking out our battle in What if Battles 2.
