<Cue: Invader Theme>

Toomi: Lady Diane, the Serpent's Sin of Envy,

Megumi: And Yu Takeyama, also known as Mount Lady

Toomi: In the world of fiction, there is no shortage of strong women, especially those that gets stronger with their powers.

Megumi: And all I want to do, is to see these girls turn into a giant woman. She's Sachi, Toomi and I'm Megumi.

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

Diane is too Huge for a What if Battle

<Cue: All About That Bass by Meghan Trainor>

Toomi: Many years ago, Diane left the Giant's Clan due to her hatred for fighting. After her departure, she formed two rock-like golems to accompany her, despite either of them being unable to talk.

Megumi: She was always alone playing with them as there were no other living beings who would accept her.

Sachi: At one time, however; Diane found an injured King lying unconscious on a riverbank and nursed the fairy back to health. King, who had taken a hard blow to his head, had lost all memories of his past and in his gratitude spent the next five hundred years playing with and protecting Diane.

Toomi: Diane later met an old man, a human, who offered Diane and King some food despite them being Fairy and a Giant. King was wary with the old man and told Diane to be careful around humans.

Megumi: Due to unknown reasons, Diane ended up getting a fever, in which King panicked due to Fairies never having fevers and went out to get herbs. However, Diane stopped him, telling him to not ever leave her side since she didn't want to be alone anymore.

Sachi: The old man who gave them food found them, and concocted a herbal medicine for Diane's fever, eventually curing her of her ailment. As soon as Diane got better, King and Diane ended up playing tag with each other, as King told her that if she caught him, he will grant her a wish.

Toomi: Diane took it seriously and caught King, but ended up getting her clothes ripped off in the fray, leaving her entirely naked, much to King's dismay.

Megumi: However, before anything sexy could happen, due to circumstances involving King however, he had to erase her memories and leave her. None the wiser, she returned back to her people to be trained under a fellow giantess Matrona

Sachi: Later about 16 years before the start of the story, Diane met and fell in love in Meliodas, not realizing she was unintentionally misdirecting her true feeling but she was then was involved in a plot by some vile Liones knights who intended to kill her and Matrona for glory.

Toomi: Although she survived the incident, Diane was made into a scapegoat for the massacre that had happened though fortunately, Meliodas intervened at her trial and recruited her into the Sins.

Sachi: As a member of the Seven Deadly Sins, Diane is shown to be incredibly strong. She was able to punch the ground and use it to stop a horde of bugs from destroying a town

Megumi: And being a giant, Diane is able to perform staggering feats of strength, able to clash with the likes of Meliodas in terms of strength and even break through barriers capable of withstanding meteors with a single punch.

Megumi: Which is called...yup...Creation where she can basically Earthbend to create things like walls, spikes and even golems of her own friends like Meliodas or Ban.

Sachi: Even if she's not a giant, Diane is no slouch in battle, having defeated Griamore and Howzer at the Vaizel Fight Festival while being human sized.

Learned to us "Creation" magic at a young age (which is about 200-300 years old)

Toomi: Diane also has her sacred treasure; Gideon, a war hammer designed for the Giant Clan. It is made of a material that is stronger than steel and weighs approximately 2,200 pounds. It is able to draw out the full capability of her ability, Creation.

Megumi: Damn, and to think Drole even believed she can become the greatest ruler of the giant clan than himself.

Toomi: Though her size may give her an advantage, it however, has a draw back where it slows her down by a lot.

Weakness

Can still be harmed

Lost to the Holy Knights, Hendrickson, Galand, Drole and Gloxinia

Her speed is reduced as a giant

Emotionally Fragile

Sachi: And being bigger doesn't make her immune to damage as she can still be harmed.

Diane: Gotcha.

Mount Lady Mounts Up for a What if Battle

https://www.youtube.com/watch?v=Qc7_zRjH808

<Cue: Cupid by Fifty Fifty>

Toomi: In the city of Qingqing, a child was born. But it was soon learned that the baby was glowing with light; and with that, it was the start of people all around the world learn that they have superpowers or better known as Quirks; with the start of the new professional called superheroes.

Megumi: And they train professional and educationally with these quirks to become superheroes. And there always has to be a leaderboard, which every hero is determined to climb their way up to the number one spot.

Sachi: And the current No. 23 spot according to the Hero Billboard Chart JP, belongs to the giant-sized crime fighter and "the world's next hottest hero", Yu Takeyama A.K.A Mount Lady.

Toomi: She would eventually become a member of a team named "The Lurkers" consisting of fellow teammates Kamui Woods and Edgeshot had formed together. Mount. Lady is a young woman who seems to enjoy the attention that being a hero gives her and she doesn't feel any shame from having to take that fame from another hero while basking in the glory.

Megumi: Can you blame her, have you seen what this woman wears as a costume, she so damn hot. Her hero costume is composed of a purple and pale tan-colored skintight bodysuit, which is accented with orange stripes. The suit appears to have a pair of purple gloves with orange accents on the edge of the cuff. The design is similar for her "boots" which are cut off at the thigh in a deep v-shape.

Sachi: Mount Lady gets her name from her Quirk power: Gigantification. This allows its user to drastically increase their size to gigantic levels.

Toomi: While gigantified, Mount Lady can easily subdue smaller targets and fight similarly-sized foes on equal footing. The extra mass also grants her enough strength to destroy buildings and other structures with ease.

Megumi: Plus, her clothes grow with her as well, imagine what would happen if....

Mount Lady

Seduction

Keen Interllect

Super Strength

Gigantification

Canyon Cannon

Titan Cliff

Toomi: Moving on... Mount Lady can activate her Quirk whenever she is agitated or excited. However, whenever she is frustrated or angry, Yu may accidentally activate Gigantification, implying that she still doesn't have full control over her Quirk.

Megumi: Yu's Gigantification's limit is 2062 centimeters or 68 feet, with Mount Lafy being unable to assume any height in-between her normal and maximum ones.

Sachi: Due to her massive size after transforming, she needs a minimum of space in order to move properly to limit the amount of damage she can cause, making the Quirk impractical in small or enclosed spaces.

Megumi: Thanks to her Quirk, she's also got some sweet moves for combats purposes. With Canyon Cannon, while in her giant form, Mt. Lady performs a flying kick that can knock any monster senseless. Kaiju meet the 50 foot woman.

Toomi: On the other hand, with Titan Cliff, Mt. Lady grows into her giant form and headbutts any enemy head on. She used this move to intercept Mr. Compress when he tried to chase after hero student Bakugo.

Sachi: Despite not being shown using any strategy in combat, Yu still proved that she is a real hero that can grasp the context of any situation quickly. She can observe and understand what plan her allies are having, and provide any possible support at critical moments without being told beforehand, like when she tried to pry open Gigantomachia's mouth, another being who possess the same power as she does, to help the U.A. High School students put the sedative into his mouth.

Feats

Knocks out a giant villain in one kick

Breaks the top of a building by growing

Punches through the length of a building with a truck

Punches apart chunks of ice

Slows down Gigantomachia's charge for a brief moment

Forces open Gigantomachia's mouth

Barely survives an attack that destroys a building thanks to Best Jeanist

Tanked getting launched backwards from a blast of ice that ravages a house

Tanked getting thrown aside into a bunch of trees by Gigantomachia

Clings onto Gigantomachia's leg while he drags her through a forest to slow him down

While barely conscious, grows in time to intercept a villain's flight so she can protect Bakugou

Toomi: Gigantomachia's Gigantification limit is known to be at least 2,500 centimeters 82 feet, making him at least 12 feet taller than her and mostly likey much heaiver than her.

Megumi: Mount Lady is a prominent user of the seductive arts, using her looks to get whatever she wants. This was shown when she convinced a stand vender at the U.A. Sports Festival to give her free food. Heck, I'd probably do the same thing and give her all my money for that body.

Sachi: She's powerful enough to take down giant-sized villains with a single Canyon Cannon kick. Mount Lady is also super tough, able take hits from strong opponents like Gigantomachia and Geten and still keep fighting. With her strength she can destroy and hold up entire building weighting several tones on her own with any assistance from other heroes.

Weakness

Plagued by financial debt due to the high amount of destruction from her fights

Refuses to work outside of the city to maintain her popularity

Sometimes accidentally activate her Quirk when she is angry or stressed out

Very Vain

Almost died from Gigantomachia

Toomi: When with her Gigantification, she can still get hurt by other weapons, and can sometimes accidentally activate her Quirk when she is angry or stressed out, causing more property damage.

Sachi: She is also shown to be quite vain as she uses her ample sex appeal to further her popularity or to gain something.

Megumi: Despite her vanity, she has shown to be selfless and will put her own life on the line to protect people in need. This shows that despite her faults, she is serious about being a hero and takes her job, and her popularity, very seriously.

Mount Lady: Titan Cliff!

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

Sachi: Don't forget to vote, comment what you think of the fight.

Megumi: Yeah, but right now, it's time for a Death Battle!

In the dense forest just at the outskirts of a city, Diane sat on a rock with a large piece of meat in her hand, ready to have her lunch.

Diane: Time to eat!

However, before she could take a bite, at that moment, she heard a loud crash from behind her.

CRASH!!!

Diane: Huh?

As Diane turns around, at that moment, something was sent flying, smashing the meat out of her hand.

THUD!!!

Diane: What the?! Hey!

Diane looks down, seeing what is basically a dead Tyrannosaurus Rex lying on top of what was once her lunch.

Diane then heard a voice saying.

???: Whew! All in a days work!

Diane turns around, seeing Mount Lady stretching her body and she shouts at her.

Diane: Hey! You ruined my lunch!

Mount Lady: Oh calm yourself dear girl, it's no big deal.

Diane: No big deal?! Lady, you're gonna regret crossing me!

Mount Lady: You think you can beat me? A Pro-Hero? Ha! You're in over your head!

Diane and Mount Lady faces off each other before Diane rushes towards the Pro-Hero.

Announcer: Fight!

https://www.youtube.com/watch?v=Wmc8bQoL-J0

<Cue: Survivor by Destiny's Child>

Diane throws a punch, forcing Mount Lady back before she punches her in the cheek.

BAM!!!

Diane retaliates by grabbing Mount Lady, shocking her as the giantess throws her across the land, sending her flying before crashing onto the ground.

CRASH!!!

Mount Lady looks up, surprised at the strength of her opponent.

Mount Lady: Wow. That girl's much stronger than I thought.

Diane draws out Gideon, rushing forward as she swings at Mount Lady, forcing the hero to swerve her body, dodging blow after blow.

As Diane swings it, Mount Lady catches the hammer midswing before thrusting her leg out, kicking Diane back.

WHAM!!!

Diane then slams Gideon down onto the ground.

THOOM!!!

The impact sends a massive amount of rocks rising up, heading straight towards Mount Lady.

Mount Lady: WHOA!!!

As Mount Lady trips over the rocks, Diane closes in, swinging Gideon at the hero.

POW!!!

The blow sends Mount Lady flying, crashing back first into a mountain.

CRASH!!!

As Mount Lady recovers from the blow, Diane smirks as she questions.

Diane: Well, ready to yield?

Mount Lady: In your dreams.

Mount Lady grabs a chunk of rock before throwing it at Diane who simply bats it back at her.

BOK!!!

Mount Lady flinches as the rock flies past her, crashing into the mountain instead.

CRASH!!!

Angered, Mount Lady shouts at Diane.

Mount Lady: That's it! You're going down!

Mount Lady rushes forward, dodging rocks that Diane throws at her before closing in, screaming out.

Mount Lady: Canyon Cannon!

Mount Lady jumps up and she thrusts her leg out, delivering a hard kick into Diane's chest.

POW!!!

Diane: WAAAHHHHH!!!

Diane screams out in agony as the blow sends her flying back, crashing onto the ground.

CRASH!!!

Mount Lady jumps on top of her, forcing Diane to raise up her arms to shield herself as Mount Lady punches her repeatly.

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

Diane simply kicks Mount Lady off her.

WHAM!!!

As Mount Lady falls over, Diane leaps on top of her, punching her repeatly.

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

Mount Lady thrusts her body up, pushing Diane off her as she gets up, closing in as she headbutts Diane in the forehead.

BAM!!!

Diane shakes her head before throwing a left hook, punching Mount Lady square in the jaw.

POW!!!

The ground shakes as both Mount Lady and Diane grabs onto each other, the two giantess wrestles and push against one another.

Trees and dirt gets uprooted as the two giantess wrestles against each other.

Mount Lady: HGN!!! Give up!

Diane: Never!

Diane lifts Mount Lady up, carrying her over her shoulder.

Mount Lady: Wait! What are you...

Before Mount Lady could finish, Diane slams her hard into the ground.

THOOM!!!

Mount Lady coughs out blood from the attack.

Diane pulls her up, giving the hero a tight slap.

SLAP!!!

As Mount Lady spun around from the blow, Diane then performs multiple hand signs, summoning two golems, Fillet and Loin.

CRUNCH!!!

The golems lunges at Mount Lady, grabbing onto her.

Mount Lady: Hey! Let me go!

Diane summons several jagged rocks, sending them flying towards Mount Lady, who managed to grab onto Loin before pulling him in front of her, using him as a human shield against the rocks.

CRACK!!!

The rocks hits Loin multiple times before destroying him, causing Diane to scream out.

Diane: Loin no!

Mount Lady then swings her leg out, delivering a hard kick that instantly shatters Fillet.

CRUSH!!!

With both golems defeated, Mount Lady mocks Diane.

Mount Lady: Are these toy soldiers really the best you can do?

Diane: No. This is.

Diane then spinning Gideon behind her back, summoning two fist like rocks that grabs onto Mount Lady, trapping her.

Mount Lady: Wait what?!

As Mount Lady struggles to free herself, Diane then creates a Golem of King and she says.

Diane: This is the best I can do. With my friends, anything is possible. It's over.

The Golem of King lunges forward, throwing one powerful punch straight at Mount Lady.

POW!!!

That one blow causes Mount Lady to scream out in agony.

Mount Lady: HUARGHHHHH!!!

Blood splatters everywhere before Mount Lady's body went off in a massive explosion of blood and gore.

SPLUTCH!!!

As the remains of Mount Lady drops onto the ground, Diane calls off her Golem and she turns around, walking away to find herself something else to eat.

KO!

<Cue: Island Song by Ashley Erikkson>

Megumi: Man, I can't get enough of a couple of big girls fighting.

Toomi: Both Diane and Mount Lady's strengths certainly came from their ability to grow bigger but shockingly, this fight is really far from close despite how fun of a concept this is.

Sachi: Especially when Diane is a legit warrior compared to Mount Lady who mostly relies more on her strength and power over strategy.

Toomi: Diane also has a more versatile set of arsenal. Like other than her own strength and fighting skills, her ability to manipulate the Earth is certainly beyond what Mount Lady even has, sure Mount Lady can still smash through rocks but that's still pretty limited.

Megumi: Not to mention Diane can also create gollums to assist her to she also has the number advantage over Mount Lady

Sachi: Diane's skills that makes her considered as one of the strongest giants makes her much stronger than Mount Lady in many ways, especially her many victories compared to Mount Lady who other than defeating one giant bad guy, she hasn't won that many fights in all her appearances

Toomi: And her versatile number of techniques and her creative ways of using rocks plus her ability to harden her skin, Diane held many advantages and many ways to defeat Mount Lady compared to her who other than having her super strength, has no other abilities.

Megumi: And we don't even need to mention Gideon which Diane can use to take down Mount Lady.

Toomi: Though Mount Lady certainly has what it takes to be a hero, Diane however, has the strength, power, weapon, experience and strategy that just towers over everything Mount Lady has ever done.

Megumi: This fight sure was one gigantic win for Diane

Sachi: The winner is Diane

Diane: The memories that I treasure are engraved in my heart. Even if I forget them temporarily or they are hidden, they will never disappear.

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

Sachi: If you want more content like this, don't forget to add this in your library and comment if you have any idea for a fight.

Megumi: Until then, next time on What if Battles...
