2 years ago (Year 848)

That day when the time of 104th Cadet years, they're on training by hiking the mountains at the North of Wall Rose. The cadets have to wear thick jackets with hoods and facemasks to cover themselves from the cold winds and snow the climate gave to them, while also carrying bags full of things needed for their next assignment during their stay in those mountains. They have to use lamps with sticks attached to light their way through the snow. This is just part 1 of their assignment, walking through the snow with bags full of heavy items.

As they trek through the snow, up ahead is a checkpoint where a cabin is located. The sun is down and a blizzard is coming so they're in desperate need of shelter. Good thing, the instructors and coaches there already built cabins right before sundown. Now they're waiting for the cadets to arrive with their flags of 104th in view.

Instructor: Come on! The goal is right here! Keep it up!

Instructor: 9 hours and 12 minutes. Not a bad time, considering the weather.

The cadets finally take a break and settle down on a campfire nearby to warm themselves.

Eren: Thought we were gonna die out there. No one ever said winter training would be this tough.

Jean: Damn, I can't feel my legs anymore after digging my foot in those cold snows.

Conny: I wish they'd let us inside already.

Sasha: I bet they're bust putting together a huge feast for us...!

Reiner: Hey, guys! Krista is missing.

Eren: Huh?

Mikasa: She was sticking with Daz since he wasn't doing so well.

Reiner: Well Daz isn't here either. Ymir and Y/n as well.

Marco: Maybe they're with the last squad?

Reiner: Can't be. The last squad led by Thomas, just arrived. They never saw those three.

All: Huh?

As the wind blew by, this added the tense feeling of concern to their comrades with the coldness and worry.

Armin: You don't think... they got lost?

Connie: Hey... They don't stand a chance if they're stuck in this blizzard.

Eren: Damn it...

Eren then gets up but before he can do anything, Mikasa grabs his arm.

Mikasa: Eren!

Eren: I'm going back out there to try and find them!

Marco: Me, too.

Instructor: Everyone, get in the cabin.

Eren: But the others...

Instructor: Yeah. We'll send a rescue team first thing in the morning.

Eren: It'll be too late if we do that!

Instructor: We won't make any more victims!

But then the blizzard came and it started to rattle the windows and the flag to be waved faster, so this only made him frustrated in defeat.

At Christa's position, they're carrying a body bag containing Daz inside. He slipped and fell into a pit when they were trekking the path they were going. Y/n just had to get down to pick him up and use the ODM gears' wires to hook himself while carrying Daz and hoist him up with the help of other cadets.

Right now, the blizzard came and they're in a predicament of being lost in the forest. Krista is pulling the bag while Ymir only watches her, not even doing anything to help out.

Ymir: Krista, give it up.

Krista: ...

Ymir: Listen to me.

Krista: Never.

Ymir: Daz already has one foot in the grave. It's his fault for training to boost his score without knowing how much his body can take. He's just not cut out to be a soldier.

Krista's cold breath is appearing, and Ymir's barely even appears while she keeps talking to her girlfriend.

Ymir: If you keep crawling to the foot of the mountain at this rate, he'll probably be a goner by then, and we'd be lucky not to be. Which means there are only two outcomes. Leave Daz here and save ourselves, or all three of us die. Which will it be?

Krista: You forgot one. That your prediction is entirely wrong. I'll be able to reach our base at the foot of the mountain... with Daz. You can go ahead of us and get back safe. How about that? There's no trouble in it for you. We'll make it back for sure. Go ahead of us.

Ymir didn't say any further as Krista kept walking through the thick snow they were stepping on, despite fumbling down to the ground due to her foot slowly getting frostbite. This only made her curious as she asked something to Krista and to hear her clearly, she removed the mask on her to call her out.

Ymir: Hey. Why haven't you asked me to help at all? Because I think right now...

Ymir gets close to her and tells her something that pops into her mind.

Ymir: You have no intention of saving Daz.

This made Krista pause in her tracks as she looked at Ymir's eyes in surprise.

Ymir: You don't care. You've resigned yourself to death already. You're hoping to die here, aren't you?

Ymir's face is now close to Krista's as she whispers something that makes Krista question Ymir's motive for doing this to her.

Ymir: How could you? I thought you were a good girl. You've gotta at least make it look like you're trying to save his life. If you want to remember you as a hero who died trying to save someone, don't drag him down with you. That's what a bad girl would do.

Krista: You're wrong!

Krista suddenly grabbed Ymir's collar in instinct.

Krista: I didn't... That's not...

She's conflicted, she can't even say her answer about this as her arms slide down and slumped in defeat.

Krista: I...

Ymir: It's you, right? The mistress' daughter who had people after your life.

Krista's eyes widened when she heard this from her.

Krista: How did you know?

Ymir: I see, so it was you after all. It's something I happened to overhear.

Flashback (Year 846)

She told her briefly of how she found out about her true identity.

Ymir: At a church in the interior, back when I snuck around borrowing things to stay alive. What a sob story it was.

She hides behind wooden fences as she overhears the conversation between two priests of their Wall Cult. Ultimately, I heard the girl was forced to join the Survey Corps.

Ymir: An illegitimate child can't succeed a powerful noble. So they just wanted to kill her, to end all the fuss once and for all. But they'd look aside if she changed her name and lived a humble life.

Flashback end

Krista was shocked to hear it from her and now pieced it together to make sense of why she was being too close to her. Ymir just told Krista about this issue if it was known to somebody.

Ymir: Don't you worry. I haven't told anyone. I don't plan to either.

Krista: Then, did you enter the Survey Corps just to find me? If that's the case, why?

Ymir: Who knows? Maybe because we're similar.

Krista: What? Do you and me... have similar backgrounds?

Ymir: Well, more or less.

Krista: That's the reason you became a soldier?

Ymir: Could be. I don't know- No, it's not.

Krista: You wanted, to become friends with me?

Ymir: *scoffs* Huh? You've got to be kidding me.

Ymir then looked straight into Krista's eyes and spat out whatever her heart could even leak out before she closed it with her tough personality.

Ymir: You and I can't even compare. We both get a second chance at life. But I'm not the one who took on a fake name. If I abandon my name and reject who am I, they win. I'm going to keep the name I have and make the best of my life. That's the only way I can get my revenge.

Ymir gets close to her with her glaring eyes pointing at Krita's gentle eyes.

Ymir: So how do you explain yourself? Are you gonna commit suicide and make everyone who ruined your life happy? Why is your desire to kill aimed at yourself? If you're so eager, use that passion to change your fate!

Krista's emotions are stirring up slowly as she denies Ymir's piece.

Krista: I... I can't... Even now... *looks at Daz's body bag* There's no way the three of us can make it out of here alive.

Ymir: There is.

Krista: Huh?

On the other hand, Y/n bolted out a few minutes ago without caring about his superiors as he passed by Keith, who didn't yell at him for insubordination except for his assistants. Keith only watched Y/n, observing him. Y/n continued walking through the snow as he found them and watched Ymir and Krista arguing.

Ymir: I can see the base straight down from here. We drop Daz off this cliff.

Krista: What...?

Ymir: Hopefully he survives the fall, and hopefully someone down there finds him. It's a long shot, but what else do we get? It's the only option left for him. Unless some miracle happens, hell be an icicle long before you drag him down.

Krista: But... But he'll die for sure if he falls!

Ymir was angered by this as Y/n watched her pissed off and carries Krista on her shoulder.

Ymir: Shut up!

Krista: Huh?! Quit it! Ymir!

Ymir: I'll do it myself, so get moving already!

Ymir suddenly pushed her sliding down to the ground and Krista was knocked unconscious by a tree she collided with and a massive snow piled on her. Y/n immediately gets there as he watches Ymir walk towards Daz before suddenly, he sees the lightning bolt and finds out about Ymir's true nature. He watches it carry Daz and bolts out to the direction of where the camp is.

Y/n: So she became a shifter... Why is she so pissed on Krista?

He checks up on Krista, and Krista sees him and finds out about her true name when he sees the memories of her nature and origin. He now realizes it's the same girl he met years ago in the aftermath of Shiganshina's fall—the one whom he will meet again and fulfill her promise of meeting his Gundam again.

Y/n: Historia...

He carries her in his arms and she gently puts her down on a nearby tree. He pulled out his GBN ID he tapped the button as a sound of whirring suddenly landed down in front of him slowly. 

It was the 00 CORE in its Proto TN armor, the Seven Sword design, with the cockpit door open. He carries her as they turn into pixels and sucked inside the cockpit and closed the door.

Krista's inside the cockpit with her vision being blurry as she can only see the blur of Y/n's back and the cockpit's design and area with programming codes contained before she was put to sleep again.

A few hours had passed inside the cabin; it was already midnight. Eren was about to go alone to find Krista, but his friends insisted on coming along with him.

Eren: It's better if you guys don't come along. As our instructor said, you'll only end up becoming more victims.

Mikasa: I'm going so that doesn't happen.

Armin: I'm not leaving Krista and the others.

Reiner: Hey. What do you think you're doing?

The three looked behind them and saw Reiner and Bertholdt with equipment gear and adding up a pickaxe and a rope.

Eren: Don't try to stop-

Bertholdt: You're gonna need a lot more gear than that.

Reiner: If you go by yourselves, you'll be in the same pickle as Krista.

Bertholdt: In a search, the more eyes, the better.

Eren: I... *calms down* Thanks. To be honest, we could use your help.

But then, more people decided to meet up with them to join the rescue.

Connie: Hey, if that's a yes, then we're coming too.

Marco: The weather's steadily improving. I think we'll be fine.

Sasha: I brought extra rations too!

Eren: *smiles* You guys...

But suddenly they hear something strange noise outside, startling them. They hear the cold blizzards outside but the most noticeable behind it is the sounds of shifting objects.

Armin: What was that sound just now...?

Eren decides to get out and check it, but as they get out, they look through the blizzard to find where it is coming from. But Sasha, who has the keen skills of a hunter, sees something in the distance. She points where she sees it and calls out to her friends.

Sasha: Over there, something's coming!

They saw where she was pointing at and what would be believed to be a person with a lamppost.

Over the next few hours, footsteps are coming down towards the camp and it was Y/n who was carrying Krista, unconscious and wrapped around by a jacket. As he walks through the snow, pushing through exhaustion he sees someone in the distance and he recognizes who it is.

Y/n: Ymir...

But as he mentions the name, Krista wakes up. Krista's eyes furrowed and she saw who saved her life.

Krista: Y/n...

Y/n: Oh, good morning Krista. Sorry if I had to.. carry you over here. *gently puts her down* But now you're awake, you can go to Ymir. I'll check up on Daz and the others, and see how they're holding up.

Y/n leaves her alone as he just smiles between the two girls and thinks of only one thing between them.

Y/n: 'Ship...'

Y/n just continues walking back into the cabin and Krista just walks towards her while feeling comfortable about what she is wearing right now. It was a simple green jacket covering her gray coat that was worn by her friends for this training. The jacket has a symbol of a flower behind it as she walks towards Ymir. Krista notices her smile having a mix of sadness and stupidity.

Ymir: Well, took you long enough. I got here before you, and it looks like Y/n's just being foolish self again. I told Reiner and the others I'd wait since you'd come along eventually. What a stupid thing I've done...

Krista: Where's Daz?!

Ymir looked over the cabin and Krista looked where she was looking and saw Daz shaking and his mouth rattling due to how cold he was. She even looked at how far she had to travel from the cliff, down to where they were now.

Krista: Up there? You don't even have a rope. So how? It would take hours for you to get down.

Ymir then stood up and just told something that Krista could hear.

Ymir: Yeah, all right. Well, if I have to trust someone, then it might as well be you. Promise me, Krista. When I reveal my secret to everyone, promise me this.

Ymir then taps Krista's shoulders hard almost as if trying to be serious towards her.

Ymir: Take back your old name and live.

As the sun rises over the mountains and the cliff beside them, they look each other in the eyes. Krista's eyes were confused but also worried about something happening to Ymir soon, and Ymir's eyes were all serious and risking everything to save her dear friend.

Present (Year 850)

They watch as Ymir begins her attack by getting on their napes and bit their napes off while Nanaba (now Marchosias) uses the Bastard Mace to attack every Titan she sees.

She swings it to her left as the Titans are knocked down before stomping their necks through the nape, killing them on the spot. She was about to be caught in a surprise attack if Ymir didn't use her as a stepping stone and bit off the Titan coming close to her. Marchosias looked at Ymir with her cold green lightning eyes as she unsheathed the mace revealing the sword as she threw it directly beside her, missing her cheek.

Ymir was surprised by this deep inside the nape but she saw who Marchosias aimed. She then saw a sneak attack on both sides, but the Titans were sliced off in the blink of an eye as the sub-arms were revealed wielding short swords. The women both looked at the Titans swarming around the castle as Ymir roared while deep inside it was a challenge for Nanaba when she looked at her before looking towards the Titans.

Ymir: 'Let's see who can kill the most of these bastards with that Gundam of yours!'

Ymir(Rogue): *to the Titans* GRAAAAAAAAAAAARGH!!!!!!

Marchosias didn't say any further as she hoisted her by the waist and gave her a head start by throwing her towards the Titans, shocking Ymir. She got the momentum and started biting off the Titans' napes, and Marchosias sliced and diced them. Ymir just looked at her in a incredulous look but she didn't care as she continue her titan-killing spree.

Conny: Is this a joke? Ymir is a Titan, too?

Krista: Ymir... Captain Nanaba...

Reiner: *trembling* T-That Titan...

Bertholdt: It's from that day...

Reiner remembers the Titan who ate their friend when he was saved as they ran away in cowardice. The tower shakes as Ymir is pulled back by Lynne and Henning to prevent her from falling off the tower.

Reiner: Krista... Did you know about her being a Titan?

Krista: I had no idea. I was always so close to her too. How? How could this be happening? That Titan... is Ymir...

Reiner: So in other words, she knew some secrets of our world. And I never suspected a thing.

Conny: Hey... Do you think she's known about it? Eren's a Titan too, but he didn't know until it happened. But she's almost as if, she's aware of it all along.

Krista: Are you saying, she might be an enemy of humanity?

Conny; I'm saying that's one hell of a secret to hide. Who knows what she's been thinking this whole time?

Bertholdt: I wonder... What could be Ymir's goal?

Krista only looks in question of Ymir's true goal. Meanwhile, Lynne and Henning are now unconscious after the adrenaline they have left in their bodies wears off after they save Krista from a fall to death. Krista then looked at Marchosias aka Nanaba.

Krista: But what happened to Captain Nanaba?

Y/n: It's just like what happened to my friend...

They understood what he meant as they were trembling during the expedition. When they hear the growls of a wolf and the vibration it gives to the whole place exceeding outside the forests. It was one terrifying moment and would never be forgotten.

Reiner: Are you saying that...

Y/n: A rage that when interacted with me, awakened something monstrous. One that could say awakens from the pits of hell...

Ymir gets back up to the tower but she is pulled down by a Titan making Krista gasp Ymir ends up getting injured but retaliates as she holds on to her life on the bricks of the tower but it doesn't last long as she is pulled down again making the cadets notice what was going on with her. She looked at her friends and looked at Marchosias who was slowly getting exhausted because of the great power of the Gundam.

Nanaba can feel the adrenaline slowly wearing off as she then closes the binders and initiates Marchosias' claws on its forearms and takes on the Titans, plunging and prowling its claws to their bodies and through the nape, kicking the other Titans who try to put her in place and jumps over who will try to get her legs.

Back at Ymir, she suddenly lets go and takes the risk of taking all the Titans in the vicinity head-on, roaring at them and continuing fighting. Her friends are watching what happening below.

Connie: W-What's going on? Is she worried about the tower falling?

Lynne: She has to be.

Krista: If she wanted to, Ymir could've used this power of hers and Gundam's assistance to escape. *realizes* It's us... She's risking her life to protect us. Why...?

Krista keeps asking about Ymir's motive of being selfless and protective of her, despite her attitude.

Krista: Why, Ymir? Why for us, you no goody two shoes?! Don't you dare die here, Ymir! Not in this, hellhole!

Connie tried to calm her down and not fall by holding down her legs but Krista didn't care as she just kept yelling at Ymir for how she was performing.

Krista: You want to be the hero all of a sudden, after all that you said to me years ago?! Hoping to go out in a blaze of glory?!

Ymir: *looks at Krista*

Krista: Don't make me laugh! Too late to think about heaven now! You're being a selfish girl, and you should know it! You'll just die protecting this stupid tower! So just get over with this tower already!!

Krista: TEAR IT TO PIECES, LIVE FOR YOURSELF!!!

Conny: Krista!

Ymir then decided to leap and throw one brick toward a titan's face and continue to throw bricks at all of them tearing down the tower. The tower is now falling like timber as everyone is bracing themselves and the two elites hold on to Y/n's recovering body.

Reiner: Brace yourselves! She's doing it!

Krista: Yeah! Atta girl!!

But then, Ymir suddenly gets in front of them everyone is in shock and Krista is just satisfied. Ymir's titan suddenly spoke just like how the Beast Titan did towards Miche before his death.

Ymir(Titan): Wanna live?! Grab on tight!

Everyone held on to her hair strands and as Ymir now rides the falling tower like a surfboard, Marchosias saw this and immediately piled all the Titans towards the falling tower, not stacking them up to make sure they stayed flat dead on the ground. As the tower falls, it causes everyone to be knocked back and cough on the smoke.

As the smoke faded away they saw some of the titans's bodies, heads, and napes splattered and squished after the crash. But some of them are even still alive, which surprised Krista.

Krista: They're still not dead?! After all of that?!

Ymir knows this as she gets a move on and Marchosias goes to assist when all of a sudden, Marchosias' movements suddenly stop making Nanaba look in shock. As Ymir fought off and bit the nape of a still-alive Titan, one of them got up and grabbed her on the head and she was pinned down to the ground, unable to move due to her back being hit hard on the concrete wall. All of the Titans started to gather around her and they started cannibalizing her.

COnny: They're tearing her apart!

Krista: No... No, please!

Krista's movements suddenly act on her emotions as she runs towards her without knowing the danger ahead.

Connie: Krista, wait!

Krista: Ymir! Don't do this to me! Damn it! We had a deal, remember?! I still haven't told you my name! I promised you!

Ymir's eyes are closed inside her titan form but open up weakly as she tries to fight back. As Krista ran towards Ymir, a Titan suddenly emerged on her left as she was shocked, knowing it was over for her.

Krista: 'No! I can't...!'

But suddenly, all of the surroundings have been surrounded by green particles. Everyone was confused about what it was as Y/n saw this phenomenon. He suddenly saw something that passed right beside his eyes and he was shocked. A T-shaped object flying around, releasing these particles and he knows what it is.

Y/n: 'A Psycho-Frame... Is it-'

Just as he thinks of who it is, a cable suddenly attached to the titan and it killed instantly, leaving behind a burning-slash mark. Krista was shocked by this as everyone saw who saved her life. The girl with short black hair and her blood-flowing psycho-frame. But her stoic face is recognizable by anyone.

Krista: Mikasa!

Mikasa: Krista, all of you, get back. We've got this.

As her body began to glow, her outfit changed as armor began attaching and being placed on her. The outfit opened to see the psycho-frame colors of green, and her head was now covered in a helmet as it transformed into a battle mask. Y/n recognizes what is happening to her as he thinks to himself.

Y/n: 'She really did it... She unlocked the Unicorn...'

Right as she becomes a Gundam Unicorn, the Survey Corps team arrives. Everyone has started their rescue; everyone gasps as they see the survey corps team slash down each of their targets. The horseback team has arrived, and Hange leads the squad.

Hange: Have the others disperse and cover the area! The rest of us will attack where the Titans are gathering!

Scout: Yes, ma'am!

Hange: Hey, wait! You're not part of the attack!

But somebody decided to leap on the frontlines and it was the stubborn boy himself. Eren circles around a Titan glares at it and gives him a parting word.

Eren: Die!

He slashed the nape with precision, and it was dead instantly. He had made his first kill without using his powers, and he seemed too proud of it.

Eren: Yes! My first kill!

But suddenly his hooks entangled and he was losing balance but somebody caught him and he landed softly on a metal hand. He looked up to see the Amazing Barbatos Lupus helped him out.

Meijin: How about I take it over here?

Meijin then slams his mace over a Titan about to attack him head-on but also uses the dead Titan as a shield against the incoming Titans. He fires his mace's rifle mode and the shots go through it. All of them lay dead on the ground and all Eren could do was watch from Meijin's fighting style.

Eren: Wow...

Scout: Damn it, Eren! That was too close, we told you to stay back!

Eren: Right! I'm sorry!

Connie: Hey, Eren!

Eren then saw Connie, Reiner, and Bertholdt approaching them as he greeted them back in surprise.

Eren: Connie, all of you!

Petra: Oruo, you're still biting on your tongue as ever!

Oruo: At least, I now have a restrainer for it thanks to Y/n!

Petra cuts the arms and Oruo cuts its legs before slashing its giant nape, killing it.

Gunther: Stop bickering already, you couple lovebirds! We already wasted time chatting while our fellow friend needed help!

Eld: I can't deny you're right, but sometimes Petra's facts always hit the mark!

Gunther slashes the nape and Eld slashes all over its arms before slashing its nape even deeper.

Mikasa then waltz through the Titans leaving behind her shining trail of death as her blade's edge began to emit a pink neon highlight, indicating the representation of her own Beam Tonfas. She slashes one of the Titan's pair of legs before slicing upward and through the nape. She continued her fight along with Hange and Moblit, despite the mad researcher having a grin of excitement about Mikasa being chosen as the next Unicorn, temporarily.

(End Ost)

After everything, the Barbatos landed in Y/n's position as Y/n is now being treated along with Lynne and Henning, both on a stretcher. Meijin walks out of the cockpit and catches up with Y/n.

Meijin: Sorry if we got stuck in the traffic... *offers a handshake*

Y/n: Well, took you long enough... *shakes his hand*

Meijin: So... She's the one, huh?

Y/n: Yeah... A possible candidate, and also Ymir's...

Everyone just watched in surprise except for Mikasa and Hange.

Armin: It can't be, Ymir is...

Hange is right beside the bloody Ymir and Krista is cradling her head in her arms.

Krista: Ymir...

Ymir opens up her eyes slowly as Krista looks at it, and smiles as she tells her the real name.

Historia: My real name, is Historia.

All can Ymir do is smile knowing the promise is now complete. As the two Meisters watch the reveal of royalty and the slave's past finally come to light, Meijin walks along with Y/n as they watch the two walk toward the immobile Marchosias who is watching this from the cockpit.

Meijin: Who's the pilot?

Y/n: Nanaba. *calls out* Nanaba, you can come out now! It's fine, it's over!

Nanaba: It's not...!

This made everyone pause and look at Marchosias when she said this. Y/n saw the Gundam's eyes glowing brighter.

Y/n: Nanaba, what's going on your side?!

Nanaba: I can feel it... something's coming!

Meijin: Who?!

Marchosias suddenly moved on its own and twitched causing everyone to be surprised. It twitched as its railgun was activated and shot down something, making everyone duck down before it fired. They looked to see the targets she hit, and it was to their surprise a human-size yellow wasp robot with red eyes. Meijin was in shock as he recognized what it was.

Meijin: That's a yellow Pluma... That would mean-?!

Y/n: *realizes in shock* Everyone, back away!

They looked at Y/n as they felt the ground shaking as everyone backed away with their ODM gear and Marchosias grabbed Ymir and Krista causing Krista yell in shock. As they backed away along with the rest of the Hange squad all of a sudden, three objects came out from the remains of the ruined Utgard Castle.

Y/n: That's...

Y/n then remembers one of the parts in the tablet description of a prophecy relating to mobile armors and Gundams of Calamity War carved in this world.

Gunther: '...the All-Knowing will grant humanity stupidity with its horrific tentacles.'

Petra: '...And the other, Marquis of Hell.'

Y/n snaps back to reality as Eren asks Y/n about the question he's been wanting to ask since after the Stohess Calamity.

Eren: Y/n, is that really...?!

Y/n: Yeah.

Mikasa: Mobile Armor...!

Y/n: 'Harael...'

https://youtu.be/sYEwtSnZAS4

Everyone other than Hange, Mikasa, Armin, Petra, Eld, Gunther, Oluo, and Eren is having shivers due to its dangling figure of tentacles and its plumes flying around to find victims. But then, Nanaba's voice came through the Gundam as it was happening like on Mikazuki's Barbatos, she was communicating with her mobile suit.

Nanaba: Marchosias, huh? That's your name, and that thing in front of you makes you hungry for vengeance?

Nanaba's left eye suddenly bled as blood flowed down from it and her nose bled too. She looks up and suddenly stretches her body and preps for what she is about to do.

Nanaba: Then good thing this will be settled here.

She lets go of the control pumps as the Marchosias' Ahab Reactors now powering up even further, forming a sound of a growling monster like in the forest during the expedition.

Nanaba: Crush that monster, for our comrades' last wish!

Marchosias' eyes turned red, removed its limiters, and started its massacre by using its claws to dig down and suddenly the ground shook up from the tremors beneath. Just then Marchosias came out of the ground with the main head of Harael poked out and the Gundam pulled out its whole figure, making Harael screech toward Marchosias.

Nanaba's nose bleeds more as Marchosias boosts forward prowling its head and then grabbing the claws ejecting it from its forearms and brutally stabbing it in the legs. She pulled out the sword from the sheath behind her and dodged the launch of its deadly claws, the claws nearly missed the Scouts making everyone startle except for Meijin and Y/n who were watching, seeing this through the end.

Marchosias/Nanaba: Is that all you have, Mobile Armor?! You're pathetic garbage!!

Harael: SKROOOOOOOOOOK!!!!!!!!!

Marchosias activates the sub-arms, revealing the long swords attached to each sub-arms as it shows the spectators its demonic appearance. This is what makes the Gundam Meisters fascinated about the Calamity War Gundams, they sure look beautiful on the outside but when they show their deadly tricks, they reveal the monster underneath them. Marchosias leaps as it slashes the left arm where it protruded its other arms a moment ago completely, leaving him with the 3 right side arms remaining. Marchosias tears its broken arms apart piece by piece like a monster which terrifies everyone.

Bertholdt: I-It's tearing its arms apart even if it's cut off!

Reiner: What kind of monster did they make?

Mikasa: 'How can I become the same power as this with my newfound abilities?'

Armin: Captain Nanaba...

Suddenly Harael retaliates by trying to swap its arms but luckily, Marchosias throws a shield at its joint, making it miss subarms as it pierces through it and slashes it off with its swords. Marchosias wraps it all up by releasing a nonstop barrage of slashing towards Harael's main head and body like an ODM gear sword style. The Marchosias then pierced the short swords across its body hopefully finding the brain of the mobile armor, or rather the control chip. But this causes Plumas to fly faster and find their targets.

Nanaba: This is good enough...

The Harael fires a powerful beam from its main head as a last resort due to how its supplies and regeneration rate are lower. But Marchosias throws the sheath of her sword towards its line of fire, making it deflect the laser everywhere. Marchosias poses its long sword for a powerful swing as Nanaba says her farewell to the weakened Mobile Armor.

Nanaba/Marchosias: This is for every member of our Scouts you killed, you monster!

She then launches a powerful at its head, decapitating it, and slices its body in half, making it dead on the ground and out of commission with its red eyes now powered off. Everyone looked in shock at what transpired as they watched the Marchosias with its sub-arms still unlocked with no weapons, looking down at its work on the mobile armor with its glaring red eyes crackling like thunder.

Y/n: Well... that happened.

Chapter 6(Season 2): Warriors
