All rights are reserved to their respective owners.

Team RWBY and friends had a long but wonderful day at their class and at one of the subjects, espers and psychics have been discussed which the girls and their classmates has different opinions on them.

Here is what some of them thinks about those beings:

Ruby: They are awesome! Able to read minds and thoughts! If I had those kind of powers I could possibly save everyone easily!

Weiss: A bit annoying if someone like them could read my thoughts, that's another way or form of breaching of privacy, someone predicting everything I thought and do will make me uncomfortable.

Blake: It can be helpful, could be annoying, but if one is my friend, he or she will know exactly what my favorite books are. If they like to read too, we will become best friends.

Yang: I would love to sharpen my mind these past few years aside from training my punches! I simply put them to the test so that I could also be as sharp-minded as well, heck! Maybe someday I could resist mind control, hypnosis even illusions so that I can finally find a way to beat Emerald!

Jaune: I guess a person like that is a great addition to my team if we can recruit another one, always wanted a new team member so that team JNPR is complete again.

Jaune then looks down and sadness remembering a certain redhead he loves.

Nora: A Psychic you say!? I am glad to welcome a new member to our very own team, not only that he or she can help me a lot of things other than you know (whispering) whooing my dear Ren to notice me more! Hehe!

Ren: A great ally to be at our side, a terrifying enemy if against us. But all I can say, they have a good semblance if they can read minds and communicates without opening their mouths.

Sun: Psychics are COOL! Cooler than any of the skills and semblance we have in Remnant. Well I wish I could have that kind of skill!

Neptune: Aw cripes! If that persons knows that I am afraid of water, they will prank me a lot, I wish if such person exist, hope they are not as prankster as Sun.

Sun: HEY!!

And with all of that, the students went on their separate ways after their academic activities, but not before letting team JNPR, SSSN, CFVY and others borrow the other copied of death battle CD's for them to watch later.

Several hours past that, team RWBY prepares for another binge watch of death battle.

Yang: So! How many episodes are we going to watch today?

Ruby: Hmm... let's just say we must watch three or four... maybe five episodes since we have a lot of time today.

Weiss: Not a bad idea Ruby, it is friday today anyway and I have no plan of doing anything this coming weekend.

Blake: Same here, no activities this saturday.

Ruby: If that's the case then, let's go! Yang, hit it please!

Yang: With Pleasure!

Yang plays the TV with a remote and the death battle intro plays, the girls gets excited.

Ruby: I'll never get tired of these intros no matter how they change it.

Yang: Yeah! It gives you hype on what's in store!

Interlude

Wiz: There are plenty of talented people in the world, but even then, only a select few have the honor of being called "prodigy".

Weiss: Just like me! Well academically speaking to say the least.

Yang: Like I always wanted to be! A great huntress one day!

Ruby: Same here sis!

Yang and Ruby gave each other a high five.

Blake: Well there is one Prodigy in our class and it is none other than Pyrrha.

Yang, Weiss and Ruby looks at Blake with sadness, Blake realising what she said made her sad as well.

The girls took a pause for that to pay respect for their fallen classmate and friend.

Ruby: ... Anyway, let's move on!

The other girls agreed.

Boomstick: But bein' a prodigy can get to one's head. Or ONE's head, if you know what I'm sayin'. 'C-cause y-you know, the guy who made both these characters is called ONE. So... yeah.

Blake: Weird name.

Wiz: Mob, the reluctant psychic powerhouse from Mob Psycho 100.

Boomstick: And Tatsumaki, the fearless ferocious esper from One-Punch Man.

We cut to Wiz and Boomstick.

Boomstick: He's Wiz and I'm Boomstick.

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

Weiss: So it's a battle between a manga artist's creations, I wonder why I feel good about Tatsumaki.

Ruby: You're saying that you can get along with her pretty well?

Weiss: Eh... pretty much.

Yang: The boy looks frail and weak.

Blake: Careful Yang, don't underestimate people for what they look like.

Mob

Wiz: As a citizen of Seasoning City, you would probably be familiar with the local criminal group Claw.

Boomstick: Maybe even the famous sex symbol and so-called "greatest psychic of the century", Reigen.

Yang: Aw yeah! Blonde archetypes for the win!

Wiz: But you probably wouldn't think twice about this plain-looking boy with a bowl cut, Shigeo Kageyama.

Team RWBY sees Shigeo with an unassuming impression.

Boomstick: Long story short, he's a pretty unremarkable student of Salt Middle School. He's the kid ya pick last for dodgeball, and he's just sorta there, takin' up space and stealin' your air.

Yang: So kind of like a cannon fodder?

Weiss: Yang what's wrong with you?

Yang: What? I only described what Boomstick explained.

Weiss: (arms crossed) Hmph! Of course you would!

Wiz: The kanji in his name can even be misread as "Mob", which means bland and boring.

Blake: Make sense, I don't know if I need to say this but, the name 'Mob' suits his appearance.

The three others looks at the cat girl with raised eyebrows.

Blake: What? I'm not insulting him or something.

Boomstick: Naturally, everybody calls him that.

Wiz: So you might be surprised to learn that he accidentally took over a local gang, unintentionally founded his own cult, and is an incredibly powerful psychic warrior.

Boomstick: Don't get it mixed up. This isn't your typical superhero secret identity shenanigans. Mob doesn't really give a sh** about any of these things. He's just out there trying to fit in by joining the Body Improvement Club, which he... sucks horribly at.

Mob passes out from running. The music stops.

Yang: Hahaha! What a wimp!

Weiss: Seems like he does not fit it.

Ruby: Poor guy! I wonder what made him strong?

Blake: He's like one of those kids that immediately gets tired after running for like three seconds.

Boomstick: Oh c'mon, man, running's not that hard! Take it from me, and I've got a shotgun for a leg.

Weiss: That goes for you dimwit! Not all people are built the same!

Wiz: Still, when his life is in danger or his friends need protecting, Mob's psychic ability manifests as something truly phenomenal.

Ruby: Wow! We just talked about Psychics earlier in school!

Weiss: So that's what the episode is about today, Psychic fights.

Boomstick: He's mega-powerful. He might not be able to run a mile without fainting, but he totally can if he boosts his body psychically. He can fly through the air, fling objects all over the place, throw psychic energy attacks, lift giant buildings, cause city-spanning earthquakes, whip up huge twisters, and more.

Wiz: He's not just an offensive powerhouse; he can mold his psychic energy around his body as a shield. While this isn't an uncommon technique in Mob's world, it's incredibly useful for him in particular, as he's one of the few psychics who can attack and defend simultaneously.

Blake: What's he lack in physical prowess he gets a lot from his Psychic powers. Impressive! He's using a different tactic in combat.

Yang: Okay, I'll take back what I said earlier! He's not a wimp! He's a badass!

We cut to Wiz and Boomstick.

Boomstick: Like when he was fighting a bunch of evil spirits all at once. Oh, talk about weird-looking. Wiz, you sure he's not just like, trippin' balls or somethin'?

Wiz: No, but you're kind of on the right track. These psychic powers are directly linked to emotions. The more sad, angry, rejected, and so on that you feel, the more powerful your psychic abilities become.

Boomstick: Hey, Wiz. Punch me.

Wiz: ...What?

Boomstick: PUNCH ME! I need to get really angry so I can do psychic stuff!

Wiz slaps Boomstick lightly.

Boomstick: Really? My gran can hit harder than you.

Wiz slaps Boomstick a little harder.

Boomstick: Wow. You think it'll work if I'm just so embarrassed about having a friend like you?

Wiz then slaps Boomstick with his robot arm, resulting in Boomstick going unconscious. Wiz then awkwardly backs away until he's off-screen before we cut back to the analysis.

Ruby: Haha! That's so funny!

Weiss: Thanks Wiz! That's what you get for showing off you dumbass!

Blake: (Smiling) He had it coming.

Yang: Yeah! Having a robotic arm is no joke, one slap can make a man go unconcious.

Wiz: Regardless, the fact that Mob's psychic powers are drawn from his emotions is a conundrum in and of itself. See, when Mob was a child, an attempt to use his powers wound up injuring his younger brother. This tragedy would scar Mob forever, terrifying him of his own ability. As a result, he suppressed his emotions for years.

Blake: And it was an accident too.

Yang: Yeah, becoming too much powerful can sometimes goes out of control, like you can do anything. That kind of mindset cost me my arm.

Ruby: That's why we always remember as a team and as friends that never be consumed by seeking power.

Weiss: Agreed, it will only stray you away from the rest.

Boomstick: But just like a needy ex, they'd still boil up in bad situations. Us readers got to see them rise with a handy percentage counter. When it hits 100%, Mob goes all-out like a Super Saiyan! He can even absorb psychic energy while in One-Hundo-Mode.

Wiz: But that's not Mob's limit. Far from it. Suppressing his powers had an unprecedented effect on his psyche. His power became an entity of its own within Mob's mind, representative of his repressed self.

Boomstick: And when things get real bad, it takes over his body in a blind rage, or blind sadness... a-a - whatever he's feelin' at the time.

Wiz: In this unmeasurable state, Mob's true prowess is revealed, and it's extraordinary. His sheer psychic aptitude increases at an alarming rate, including his absorption ability.

Hanazawa: My powers are being sucked in by Kageyama. All of the energy in the atmosphere... Are you telling me his vessel is able to handle this much?

Yang: Oh boy! What a terrifying guy! R.I.P to the persons who is about to be at the receiving end of his rage or sadness.

Weiss: From what I read, Psychic or espers on a blind rage can really screw you over, the bodies of their opponents tends to be unrecognizable due to how many twists and bend done to them telepathically.

Ruby: That is terrifying indeed, dying via crushing in all horrific twists and turns.

Blake: (Shivering) That is one horrible fate I don't want to end up with.

Wiz: And while he's often unconscious while his inner self takes over, his questionable state will continue trying to achieve whatever his most recent objective may be. Whether that's taking on the criminal organization Claw, or confessing how he feels to his crush.

Boomstick: All right, I get it, the guy's super strong. So let's figure out just how much psychic power he's got bottled up. Check this out. While smashing this ugly joke through a building, he went from zero to kick-ass so fast he caught fire.

Wiz: Taking this feat literally, to get this result, he would have to be reaching an ablation speed over five times the speed of sound.

Ruby: Like a meteor entering an atmosphere?

Weiss: Precisely!

Boomstick: Fast. But not as fast as a bolt of lightning, which he was quick enough to catch with his shield!

Wiz: That's not all. In his duel with Claw's boss, Toichiro, Mob took this huge crushing hit. Scaling this massive handprint crater to a nearby building --that one-- and applying the resulting fragmentation of rock, we found Mob survived an attack worth over 80 tons of TNT.

Yang: Damn! No one in Remnant would survive an attack that big!

Boomstick: Nah, that's small-time for Shiggy. In the same fight, he psycho lifted hundreds of buildings into the air. Look at that thing! Suddenly, I have an unshakeable urge to go play Katamari Damacy. (The music stops abruptly while humming the theme of the video game) Do do do do do do do~, somehow these things will make some stars~.

Blake: I- eh! ... he formed a gargantuan boulder made our of buildings!

Weiss: What a weird but interesting game!

Ruby: Ooooh!! I am so going to play that one once I get my hands on it! (Excited)

Wiz: Ahem, not only is that millions of tons of stone and concrete, but simply creating this orb pushed away the clouds.

Boomstick: Okay, I know what you're thinking. "Guys, that's not impressive! Clouds are just fluffy balls of cotton candy." Now, I hear you. I thought so, too. But turns out, that's not true at all, unfortunately. To move clouds in real life, you need a freakin' hydrogen bomb!

Blake: Huh! Moving clouds by a weapon of mass destruction.

Yang: And some people say that Atomic and hydrogen bomb's purpose is to destroy, I think it found another purpose.

All three looked at Yang again.

Yang: H-hey! I-I was just joking! Calm down girls!

RWB: Suuuuuurree!!

Wiz: So it's quite impressive when, on another occasion, Mob gathered all these clouds himself. By measuring the area and multiplying by average cloud density, this feat comes out to around 30 gigatons of TNT.

Boomstick: Twenty times the combined destructive capabilities of all the nuclear warheads in the world.

Popup: It should be noted that Mob did destroy an illusory mental world created by Keiji Momagi. It is unclear if this translates to Mob's capability in the real world, where he has never displayed such destructive power.

Wiz: Granted, Mob isn't all-powerful. For example, once while absorbing an explosive attack, he reached a definitive limit. Though he compensated by redirecting all that psychic energy into some broccoli seeds with... interesting results.

The TV shows a giant broccoli in the middle of the city.

Boomstick: Oh man, it's gonna be hard to hide that one under the table.

RWBY: Whoa!

Ruby: H-how did he made that broccoli that big?

Weiss: So big that it can feed the entire city for several years!

Blake: Imagine the food you can cook with that huge supply.

Yang: If that happen here, he could easily end world hunger crisis!

Wiz: In time, Mob eventually reconnected with his repressed self, fully accepting his past and his powers.

Boomstick: So look out! He may look like a total dork, but this is one middle schooler you don't wanna try stealin' lunch money from.

Mob: Can you feel it...? Rage...! Burning in me!

Mob is shown with red eyes and a massive aura as he enters his 100% Mode.

Yang: I have to say, I really don't want to piss him off.

Weiss: A good choice on your end, also here I am agreeing again with you, what a weird feeling.

Blake: Again, I won't disturb someone like him, I don't want to end up like a messed up pretzel.

Ruby: His powers are cool though! I wish I could be as strong as a Psychic like Mob.

Weiss: We all are in our own right. Now on to the next combatant.

Tatsumaki

Wiz: In a world filled with monsters and villains which threaten the survival of humanity on a daily basis, it's a stroke of luck that mankind has its fair share of saviors in the form of superheroes.

Yang: Looks like superheroes are prominent and a famous job in that world, my dream!

Ruby: That's just like us here in Remnant once we graduated combat school.

Boomstick: And some of these heroes are so powerful, they can crush all the baddies without even laying a finger on em'.

Wiz: These are espers, superhumans who possess powerful psychic abilities.

Weiss: Espers?

Blake: Psychics?

Yang and Ruby: Why not both?

Boomstick: And one of them is a girl named Tatsumaki-

Boomstick sees the webcomic version of Tatsumaki and the music stops abruptly.

Boomstick: Ahah! What the?! Is that real?! Why does she have cinnamon rolls stuck on her face?

Ruby: Whoa! Hahaha! What is up with that illustration?

Yang: Pfft! That's an ugly looking drawing!

Blake: Wow! Thanks a lot Boomstick! I can't unsee the cinnamon rolls on her head now!

Weiss: T-thats... let's just say that image is a bit cursed.

Wiz: Well, let's just say ONE is more well known for his excellent storytelling than, say... his art. Regardless, Tatsumaki's psychic abilities were extraordinary, even at a young age. So much so, she was taken from her family to be detained and studied at a research facility. She was seven years old.

Ruby:(Sad) That's... cruel!

Blake:(Angered) And as a kid too, such innocent soul don't deserve it.

Boomstick: So, not the best childhood, obviously. Lucky for her, she got out thanks to a surprise rescue by the hero called Blast. Who... blasts things? I guess? Eh, no one really knows.

Weiss: Of course it is captain obvious!

Wiz: Either way, Blast's rescue changed Tatsumaki's life forever, and he left her with one very important lesson: "When the time comes, don't expect someone to save you".

Boomstick: That's kinda harsh. He is supposed to be a superhero, right?

Yang: That's the opposite of what a superhero would think of. Also he does sounds like your sister Weiss.

Weiss: Yeah, I could see that. Just like what Winter always said: "I'm not always going to be around to save you, Weiss." (Doing a Winter Schnee voice impression).

Wiz: Whether it be she was inspired by his heroism or torn by his contradiction, Tatsumaki decided to take up hero work for herself. Thus, she took up the mantle, "Tornado of Terror".

Ruby: What an awesome hero name. I wonder what mine would when I graduated and become a licensed huntress.

Yang: Yeah sis, me too! I want one badass name once we become full -fledged huntress.

Boomstick: Yeah, I know what you're thinking, "Doesn't that sound more like a supervillain name?" And you might mistake her for one too, 'cause she's... kind of a brat.

Weiss: I can of agree with Boomstick about the superhero name, feels really weird to say that one.

Blake: Looks like we got another prima donna in our list.

Yang: Ooooh! You mean she acts and behaves just like Weiss?

Weiss: Hey! That's rude you know!

Wiz: Well, she is the best at what she does and she knows it. So, she often seems arrogant and rude. With her psychokinesis, she often floats above her opponents, looking down on them literally and figuratively.

Yang: Yep! That really sounds like Weiss.

Weiss: Yang!

Boomstick: Her favorite thing to do is throw rocks at people. Big rocks, small rocks, rocks from outer space, doesn't matter. If it's vaguely rock-shaped, it's flyin' at ya. But she doesn't discriminate; she's also fine throwing other things like trains, schools, people, even a giant octopus.

Blake: Better avoid rocky or hard objects when fighting this kind of person.

Popup: Fubuki once created an earthquake measured as 6 Shindo in the Japan Meteorological Agency Seismic Intensity Scale. 6 Shindo roughly equals magnitude 8. Later quakes created by Tatsumaki were measured as being higher in output than Fubuki's.

Ruby: Wow! She can create massive earthquakes that easily. Bet the people of that Earth breathes a sigh of relief that she's a hero than a heartless villain.

Wiz: Not only that, but she can alter the direction of gravity, create town-spanning barriers, twist up a human body, cause magnitude 8 level earthquakes, and spin up enormous whirlwinds. Fitting for her namesake.

Weiss: Being twisted like a pretzel is one of the worst things to happen before dying. And I don't want that happening to me.

Boomstick: And that's not even half of it. She's the most powerful esper of them all, even better than her older sister, Fubuki.

Ruby: Weird, she looks older and mature.

Wiz: Actually, that's her younger sister.

Text then show up on the screen, stating that Tatsumaki's 28 while Fubuki's 23.

Boomstick: Her- wait, what?! Man, anime's real confusin'.

Yang/Ruby: Wait what!?

Weiss/Blake: Anime is weird.

Wiz: But given her past, even with her sister beside her, Tatsumaki has some serious trust issues.

Boomstick: She doesn't even want Fubuki to have friends. Chill out, lady. Friends are important. Right, Wiz?

Wiz: Sorry, what?

Boomstick: Aw. Whelp, he had his chance.

Yang: Hahaha! Boomstick got denied!

Weiss: Take that you dumb sucker!

Wiz: Anyway, manipulating objects and organisms is only part of her skillset. Tatsumaki's power truly shines when it comes to precision.

We cut to Wiz and Boomstick.

Boomstick: Oh yeah, she's so talented, she can use her crazy mind power to have full control over television!

Wiz: Uh... Yeah, sure, but that's not really what I had in mind.

Boomstick: Change! CHANGE!

Boomstick tries to psychically change the TV screen.

Weiss: You're not an esper you idiot!

Wiz: Well, Tatsumaki has some level of control over a person's chi, or, as it's known in traditional Chinese culture, vital life force. If she can overpower her opponent, she can use their own chi to disable or even kill them.

Wiz uses a remote to change the channel on the monitor to The Simpsons and hides it behind his back right before Boomstick opens his eyes and notices the screen.

Boomstick: I did it! I'm psychic!

Weiss facepalmed at Boomstick's antics while the rest of the girls laugh at what Wiz did.

We cut back to the analysis.

Wiz: Against other espers, she can spiral her own energy to redirect theirs, and even suppress their powers in an instant.

Popup: In the world of One Punch Man, it generally takes a combination of physical superiority and extreme mental will power to successfully counter an Esper's abilities.

Ruby: So she is the superior esper.

Weiss: Or a superior hero.

Boomstick: Yeah, Lady Tornado can block their psychic-ness whenever she wants, so long as they're a weaker esper than her, which basically means everyone. One-Punch Man, meet the One-Thought Woman. Seriously, this chick is so powerful, she pulled a meteor from outer space.

Wiz: Well, while that move is pretty well known, it technically is not canon into the original source material. However, that doesn't mean it's off the table, as it turns out her other accomplishments prove she's more than powerful enough to pull it off.

Boomstick: Just look at her liftin' up this... Uh... What am I lookin' at here?

We see an image of Tatsumaki using her psychic powers to lift an underground hideout into the air.

Wiz: Good question. Thankfully, ONE was kind enough to include these lovely labels identifying Z-City and an underground hideout. Now, Tatsumaki is psychokinetically lifting the entire hideout, which was previously stated to reach over fifteen hundred meters deep. As for the city, the world of One-Punch Man is based on real-life locations in Tokyo. So at the very least, we could compare Z-City to a smaller district like Ginza, which consists of about 215 acres. With the size of an average building in that district in mind, and thus scaling the building to the hideout and then to Ginza, we found that Tatsumaki must be lifting over three billion tons of rock.

Boomstick: That's like lifting the entire Great Wall of China 62 times. More than powerful enough to pull a meteor from the sky.

Blake: Her mind can hold up an entirely heavy object like that!?

Weiss: Not to mention that she can call out large chunks of space rock just to beat her enemies.

Wiz: When the alien invader Boros attacked City A with a hailstorm of giant bullets, she was fast enough to stop them in midair and turn them back on the enemy ship. Scaling these bullets to the height of a human and gauging by the amount of damage they could cause, the bullets must have been moving eighteen hundred times faster than sound.

Boomstick: She's tough enough to survive an attack that's 300 times the Earth's gravity, which probably explains why she could push through crazy g-forces while flying and fighting against the One-Punch Man himself: Saitama.

Wiz: By looking at the distance they flew in such a short timeframe, they were likely moving more than 36 times the speed of sound.

Boomstick: Which is awesome, but she still didn't win the fight.

Weiss: She's tough.

Ruby: And she's resilient enough to last a fight.

Wiz: It was actually a rather humbling experience for her, finally realizing that perhaps she isn't the most powerful person alive.

Yang: Yeah! I mean brain power vs. Brawn power? Brawns always wins.

Weiss: That's not how it works you blockhead!

Boomstick: I mean, all espers have limits, including Tatsumaki. Their psychic power drains them of energy, so they can get worn out to a point where they can't do their psycho magic for a while.

Wiz: Also, she generally has to focus exclusively on either offense or defense, so when she's on the attack, her guard is lowered. Something a skilled enough opponent can certainly take advantage of. Also, should an esper like Tatsumaki suffer a serious head injury, their powers become more difficult to use.

Boomstick: So maybe she's not quite the unstoppable goddess as she thought she was, and after gettin' that memo, she finally loosened up a bit. She even let her sis hang out with her friends instead of throwin' them into a wall or somethin'. Aw.

Wiz: Yet at the end of the day, the idea that anyone could even hope to match the Tornado of Terror's pure psychic power seems laughable.

Tatsumaki: You disgust me. Get lost!

In Saitama's perspective, Tatsumaki is pint-sized and poorly drawn.

Saitama: What's with the attitude from... this lost child?

Ruby: Hehehe! She indeed looks like one!

Yang: Yep! Same attitude with the Ice queen, she's like Weiss but as an esper.

Weiss: Stop lumping me to her!

Blake: Yeah! Totally the same!

Weiss: Blake! Not you too!

Wiz: Alright! The combatants are set! And we've run the data through all possibilities!

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

Ruby hits the pause button.

Ruby: Okay it is time to vote girls! Who do you got? Me Tatsumaki, why? She is the superior esper.

Weiss: Me too, Tatsumaki. She may have the attitude but she can definitely hold her own. Also...

Yang/Blake: What?

Weiss:(Embarassed) She reminded me of myself.

Ruby, Blake and Yang smiled then laughs at the icy princess.

Yang: She's finally admitting it!

Blake: She's finally starting to believe!

Ruby: I'm proud of you Weiss, you're starting to face reality!

Weiss: (blushing in embarassment) S-SHUT UP!! ALL OF YOU!!

Yang: Hehe! Okay then, I'll go for Mob.

Blake: I don't know, I'll just go and enjoy watching this fight.

Ruby: Okay! Then let's get started!

Ruby then bits the play button.

We see Shigeo Kageyama, better known as Mob, walking through the city holding a map as he realizes he is lost.

Mob: Oh. I'm lost.

The Tornado of Terror, Tatsumaki appears behind him.

Tatsumaki: Hmph. What are you doing, dummy? Get out of here.

Mob: Can you help me? Do you go to the middle school here, too?

Two certain words in that dialogue greatly offend the childlike twenty-eight year old as she gets up close to the young adolescent fourteen year old teenager.

Tatsumaki: Middle school? Know your place!

Ruby: Wow! Got offended so quickly.

Blake: Just like a certain person we know.

Blake and Ruby looks at each other then looks at Weiss with the ice queen clueless at what they are thinking.

Weiss: What?

Ruby/Blake: Oh! N-nothing!

The two immediately looks back at the TV.

Tatsumaki slams Mob to a building with her telekinesis as Mob gets off easily and strokes the dust off his uniform, much to her obvious surprise.

Mob's Percentage: 62%

Yang: Oh! That was fast!

Mob then confronts Tatsumaki.

Mob: You shouldn't use your powers on others.

The Tornado of Terror, now angered, lifts the building behind her, turns it to dust and launches it at Mob only for the White T-Poison to redirect it at her as she uses her barrier.

Tatsumaki: You think you're impressive? I'll crush you in five seconds FLAT!

Blake: That's a bold assurance.

Yang: She's an esper and you're just a huntress, can you say the same if that were you?

Blake goes silent.

The bratty esper slams gravity at him as Shigeo uses his barrier to protect him, with great strain.

Mob's Percentage: 75%

Tatsumaki flicks Mob through a building and slams him to another building with her telekinesis.

Mob's Percentage: 81%

Yang:(Excited) Oh boy! He's getting there alright!

Tatsumaki then grabs Mob and flies him up a building destroying the top as she then slams Mob to the ground with contempt, destroying a building as she looks down.

Mob's Percentage: 100%

Ruby: And there he goes!

Mob gets up to his feet as he is now in his 100% form. With rage being the dominant emotion, he raised his open illuminated palm to his attacker, a menacing look in his eyes.

Mob: Time to teach you a lesson.

No sooner he said that Tatsumaki was caught off guard and sent yelling into the street below, face first in a crater.

Tatsumaki: What?!

Mob: By the way, just so you know...

Mob telekinetically pulled her in, only to forcefully send her flying. He soars off in pursuit, catching up and delivering a hard kick upward into the air. The teen prodigy again caught up with her.

Mob: ...this is your fault.

RWBY: Daaaaaaaaaaammmnn!!!

And again Tatsumaki was greeted with another vicious kick, all the while sent flying and crashing into a nearby skyscraper. Despite the bad landing, the green-haired esper was more incensed then injured.

Tatsumaki: What?!

Her foe's hand immediately shuts her up. And Mob wastes no time slamming and smashing her body into the remaining skyscrapers within range. He was just about to finish this off with a rough landing on the pavement below when Tatsumaki quickly erected her own psychic barrier, shaking him off, gaining some distance and leveling more of the environment. Floating around under her power, were large glowing debris.

Mob is down but far from out. He fired twin streams of his power only for the Tornado of Terror to effortlessly swerve around them before channeling them herself and forcing them back to the sender. The teen countered this with another absorbing barrier.

Tatsumaki had decided this bout has gone on long enough. With enough psychic force, she telekinetically lifted up an enormous chunk of city landmass. This intimidating sight distracted the male esper for a moment, before realizing his female counterpart had retreated to a safe distance. Glowing with green energy, she mentally cut the landmass in half and sends it closing in on Shigeo like a city-sized sandwich.

He immediately activates his shield.

From Tatsumaki's viewpoint, the colossal merging was successful. She turns back in self-satisfaction, confident that her opponent is pulverized.

Ruby: No ordinary fighter can escape such massive crush like that.

Weiss: She is indeed a very powerful foe.

Tatsumaki: How easy.

Her smugness instantly dashed when the conjoined landmass exploded in a blinding light.

Mob's Percentage: ???%

Yang: OH BOY! THINGS ARE GETTING EVEN MORE CRAZY!!

Mob awakens his ??? form and summons up many building ruins and debris, surrounding both espers. The Tornado of Terror outspeeds the assaulting barrage before closing back in to collide with him. That once proud, arrogant tone is now reduced to undignified screeching.

Ruby: He's pissed!

Tatsumaki: You think you're a big shot?! Try this!!

She then throws two buildings at Mob, hoping to crush him. It doesn't work, as he effortlessly dissolves them in a deep purple void. She raises her hand upward, like calling forth some help from above, only for her opponent to sock her square in the face two times before dropping a floating car on her.

Weiss: Ouch!

Blake: getting one-two comboed there.

Now helplessly caught, Tatsumaki was sent upward when Mob uppercut her, the car cut clean in half, and sent her back down brutally with another punishing blow.

Now bloodied and battered in a crater her body created, the S-class hero could only turn in time to see ??? Mob point a single finger at her. His esper power control was much quicker as Tatsumaki's arms and body were painfully twisted, mangled and contorted around each other, binding her. Despite the extreme agony, she handed out one piece of advice.

Yang: Aaah! That must've been hurt if that is someone else!

Weiss: Oh my! That's so gruesome!

Tatsumaki: You should pay more attention.

Coming down rapidly behind Mob from the heavens, was a burning meteor on a direct course. The teen was ready to shield himself with yet another psychic barrier, but with what esper strength she still had, Tatsumaki channeled enough power to shatter the barrier, leaving Mob open to a fiery impact.

Yang: Oh no! Mob!

Once the dust had cleared, the green-haired prodigy realigned her mangled limbs and looked down at the body of Shigeo Kageyama, crushed under the undamaged meteor. Her haughty attitude returning, she issued one last mental command; the still-living boy dissolved via a mini psychic tornado.

Tatsumaki: Nobody beats me.

K.O!!!

Yang: I lost again!? Noooooooo!!!

Ruby: Whoa! What an epic fight using telekenesis! City's more than broken though.

Blake: I admit, the fight in the air is awesome to watch.

Weiss: As expected, she is called the most powerful esper of all.

We cut to Wiz and Boomstick.

Boomstick: Whoa, that was crazy! I thought for sure Mob would win with his sucking power!

Yang: I thought so too! Especially once he entered ??? Form.

Wiz: This was an incredibly close match. Honestly, if we were to run through this fight a hundred more times, Mob could reasonably win 40 or so of them.

Blake: That might be a fair title match fight like that in boxing.

Boomstick: But we're not here to find out who wins 40% of the time. Mob had tons of awesome abilities which gave Tatsumaki a hard time, but she still has the stuff to pull off a win more times than not.

Ruby: Yeah it gave her a challenging fight to deal with.

Wiz: Right. First of all, Tatsumaki had a notable advantage when it came to training and experience.

Boomstick: She's a top-ranked superhero who was trained from seven years old fighting a middle-schooler who never wanted to use his powers in the first place.

Weiss: Doing those things at seven years old. Imagine if we trained in combat schools like Beacon at that age.

Ruby: I think we would be more stronger.

Wiz: She was faster, too, given her reaction against Boros' bullets moving over 617,000 meters per second.

Boomstick: Sure, Mob reacted to freakin' lightning, but believe it or not, that's still technically slower.

We cut to the post-analysis.

Wiz: See, a lightning bolt technically has two different speeds to consider. First for the slower leader of ionized air going down, and second for the faster flash going up. Given that Mob was reacting to a projectile moving down towards him, this can only mean he was reacting to the leader, which moves 98,000 meters per second. More than six times slower than Tatsumaki.

Blake: So if you are fast enough you can technically dodge lightning.

Yang: Might as well try it sometime.

Weiss: Yang, don't be crazy, you're just going to electrecute yourself and fry your whole body.

Yang: seems pretty exciting to do though.

Weiss: Ugh! You're so hopeless.

Boomstick: So, even though Mob had the edge of being able to attack and defend at the same time, Tatsumaki was a lot quicker than him, so she could switch between attacking and defending fast enough to counter Mob whenever she really needed to.

Ruby: Yep! Simultaneous attack and defense is the only advantage he held against this fight.

Popup: Mob has never used Astral Projection for possession, and it's unlikely his spirit could persist after death. Also, while Tatsumaki has never encountered spirits, it's established in Mob Psycho 100 that an Esper's barriers repel them. Given her immense psychic power, its extremely unlikely Mob's spirit could affect her in any meaningful way.

Wiz: Still, that alone doesn't mean Mob couldn't have eventually scored a fatal blow. All of this would mean nothing if Tatsumaki couldn't overpower Mob's absorbing shield.

Boomstick: His awesome power of suck.

Weiss: Stop making it sound weird you dimwit!

Wiz: Right. We know Mob's, uh, sucking shield had a limit given how he was forced to transfer absorbed energy into those seeds, growing a massive head of broccoli in an instant. We can actually use this broccoli to get a general idea of Mob's absorbing limits. Broccoli typically requires 143 kilojoules of energy to grow 1/10th of a kilogram's worth. Scaling this giant one to the nearby buildings, we found it to be 21 million times larger than the average broccoli. This means Mob must have transferred enough energy to equate to about 1.6 megatons of TNT.

Blake: Not containing those excessive power means totally giving it up just to store it to something else. Well everyone has their own limits.

Popup: Mob's ???% form most likely possesses a much higher limit than his 100% form. However, like with his 100% form, the ???% form's absorption shouldn't surpass its own power output, which is still much less than Tatsumaki's.

Boomstick: Yeah, but how about the energy Tatsumaki used to stop and redirect those giant bullets? Those things are huge solid shells with no explosive component, given how Saitama here was able to crush one without triggerin' a big kaboom. And they could wipe out a whole city!

Popup: In the game Mob Psycho 100: Psychic Battle, Mob created a blast visible from outer space. Mob never displays this level of power in the main series, our primary source material. If it were included, it is unclear if it would change the verdict.

Yang: Oh they would change the result if they decided to do a rematch of this fight, well once that info is canon.

Weiss: Well for now I will savor this victory.

Yang: Just so you wait until I get a win ice queen.

Weiss:(Prideful) Hoho! Whatever.

Wiz: We're shown that the shells destroyed most of City A in one shot, and we can see how much damage they dealt with Boros' ship when Tatsumaki turned them around. With this data in mind, the height of Boros' ship, and the already calculated bolt speed, we determined the energy she displayed here must have equaled at least 470 gigatons of TNT.

Boomstick: Way more than Mob's big cloud feat, and more than enough to shatter his shield all at once. Tatsumaki was just too damn powerful. And it's not like Mob could absorb giant rocks thrown at him either.

Wiz: Certainly. Mob's unique powers were generally passive and defensive, whereas Tatsumaki's were better suited to precision strikes and deadly blows. Once Mob's barrier was down, she had plenty of options for wrapping things up, whether it be blocking his psychic power, controlling his chi, or simply crushing him herself.

Popup: It's important to emphasize that Tatsumaki's psychic power is so much greater than Mob's that she could overpower his own defenses at any point.

Boomstick: And her powers weren't dependent on her feelings, so she was always at full strength, no matter what the situation was.

Blake: True! Sometimes emotions can block your focus when it comes to battle.

Yang: Yeah agreed! It can blind you to throw punches randomly, making you vulnerable to attack.

Ruby: Glad you learn your lesson then and there Yang.

Yang: Yeah, I'm glad.

We cut to Wiz and Boomstick.

Wiz: Mob certainly had the skill and ability to put up an incredibly close fight, but Tatsumaki's experience, speed, and power put an end to this prodigious battle.

Boomstick: She just had the "esper-ience" she needed.

Yang: Nice pun Boomstick! That's so funny that I ended laughing Pyschically! Hehe!

Ruby, Weiss and Blake all groaned both to Yang and Boomstick.

Wiz: The winner is Tatsumaki.

Ruby Pauses the video.

Weiss: Well I have a real good fun at that matchup, it feels like I am the one who wins.

Yang: Mission failed, we'll get 'em next time, I admit defeat Weiss.

Blake: I'm also happy with the result, the fight was entertaining at all.

Ruby: Okay, now that's done, let's see whose up next.

Team RWBY all focus on the TV as Ruby press play to continue their watch.

UP NEXT

Flashback of previous death battle episode with Deadpool.

Deadpool: You can't have a season of Death Battle without Deadpool right?

The last words of that sentence echoes more slowly and distored.

Weiss: Oh come on! Not this prick again!

Ruby: Whoa! Deadpool for the third time in this show!

Blake: I wonder who is his opponent this time.

Yang: Wait girls, looks like there is more.

Wiz: Hey Boomstick.

Boomstick: Yeah Wiz?

Wiz: I think I might know a way how to get rid of Deadpool once and for all.

Yang: Oh my they do?

Weiss: Huh! Wish it is for good then.

Then the girls saw a crazy face with a sinister grin and blood splattered in it.

Blake: Whoa! Scary!

Ruby: Who is this guy?

Then a message from the screen pops up:

LET'S KILL DEADPOOL

Then reveals the next matchup.

Deadpool vs. The Mask.

Ruby: Okay! This is exciting!

Weiss: Well what are we waiting for? Let's watch the next episode to see if they can get rid of this loudmouth once and for all.

Blake: I wonder how they will do it.

Yang: You heard Weiss Ruby, Dew it!

Ruby: Okay!

Ruby then puts the next disc to the player and she press play.
