Attack on Titan: the Metal Titan (Mikasa x oc)

Chapter four: the Battle of Trost and the return of the Metal titan part 2

-A few minutes after the Colossal titan dissappeared, and what's his face's speech-

Asura stood on a rooftop, looking at the horde of titans aproaching. 'Fight' was the only clear thought in his head. The only thought that counted at the moment. Eren, Armin, Mina and Thomas joined him. "So...think you can kill more than me, Eren?" Asura asked Eren, "How much?" He replied, "A month's worth of ration cards, and my respect." Asura said, Eren smirked. "You're on!" He said, Mina giggled. "How you two make a game out of hopeless fights, I'll never understand." She said, "Besides, you three aren't the only ones who want to join the Scout Regiment." Asura smirked. "Well, we best start getting hands on experience!" He said, "Alright! Stay together, and follow me! Let's push these bastards back!" Everyone let out warcries, and took off. Asura leading the charge. As they got closer, Asura picked up on the scent of human blood...freshly spilled. "Holy hell! The Vanguard was completely wiped out!" Eren shouted, "For all their big talk, they acomplished fuck all!" Asura added, he then heard movement on the left of him and his squad, and turned to see a 13 meter Abnormal titan. "WE'VE GOT AN ABNORMAL!" He shouted, "SCATTER!" Most of the squad followed his order. But Thomas got caught by the Abnormal. The look on his face was one of pure terror. "I'm sorry..." Asura mouthed, Thomas mouthed 'live' before he was swallowed whole. As the Abnormal ran away. Eren's anger got the better of him. "YOU BASTARD!" he screamed, he would've gone after the titan, had Asura not stopped him. "Eren! He's gone! Thomas is gone! Damn it, there's nothing we could do!" Asura said, Eren wasn't happy about what happened, but listened to Asura. "Come on! We have to keep moving!" He shouted, the group of four now, were on the move again, but after a few miles, Eren's leg was snapped off by a 5 meter Crawler. "Eren!" Armin shouted, "Damn it!" Asura cursed, suddenly his leg was grabbed by a titan. Mina gasped. "Tsk! Hands off!" Asura said annoyed, he then cut off the finger that had him trapped and moved to Eren. "Mina, watch your line!" He shouted, Mina was then brought down by a 3 meter titan, and hit the wall hard enough to daze her. "Shit!" Asura hissed, he then shot a hook that hit the back of the titan's neck. He then started spinning (like Levi) and cut it's nape off. He then picked Mina up before heading to the rooftop Eren was on. "Damn, this looks bad." He said to himself, he turned to Armin who was paralyzed in fear. Asura then flew over to him and tried to shake him out of his fear. "Armin! Hey, you in there!?" He shouted, "This is it...we're going to die here." Armin muttered, "Hey, pull yourself together, Arlert!" Asura ordered, this seemed to work as he was snapped out of his fear and looked at Asura. "A-Asura?" He asked, "Yeah, I'm here." Asura said, "Listen to me, Mina's out cold, and if we don't do something Eren's gonna bleed out." Armin saw what Asura was talking about, and almost panicked. "Hey, hey. Eyes on me." Asura said sternly, "I need you, Armin. I need you right now." The two then stood up, and headed to their temporary outpost. "How bad is it!?" Armin asked as they landed, "Mina has a small concussion, but I'm more worried about Eren at the moment!" Asura replied, "Damn..." Eren groaned, as they got to work trying to stop the bleeding stump, Asura noticed it was steaming...and regenerating. (Eren's leg.) He thought, (It's regrowing!) Armin noticed Asura's wide eyed face and saw why. "Do Eren a favor...tell no one of this, not even Mikasa." Asura told him, "R-right." Armin stuttered, (This healing power...) Asura thought, (Grisha, what have you done to your son?) Asura then heard heavy footsteps aproaching them. "We're out of time!" He said, "Wait, where are you going!?" Armin asked, "To buy you some more." Asura answered calmly, drawing his knife jumping off the roof, he was on, and cut his left hand open. A red pillar of fire erupted from him. As Asura started being surrounded by bone, muscle and metal. After a few seconds, his transformation was complete. "Get Mina to safety!" The Metal titan ordered, "Asura...is the Metal titan!?" Eren shouted in surprise, Asura let out a demonic roar as his entire body started glowing red hot. His arm then transformed into a sword, he then swung his weapon and decapitated the 15 meter titan, severing the nape in the process. Another titan, an Abnormal, ran towards Asura as his chest started glowing reaching his neck. Asura threw his jaws open as a stream of fire erupted from it. The Abnormal was burned to cinders in an instant. Asura roared again as he charged another 15 meter titan, grabbing its face before doing a full 360 degree spin and throwing it at an Abnormal heading towards civilians.

-Wall Rose evacuation gate-

An Abnormal was heading towards the mass of civilians that were trapped due a merchant being greedy. Before any of the soldiers or Mikasa could reach it, a titan flew past them, hitting the Abnormal with enough force, that it exploded into pieces. Mikasa turned to where the projectile titan came from. What she saw caused hope to blossom within her. The Metal titan had reappeared after five years. It was taller than last time, standing at 23 meters. (So you did come back...) she thought, "Is that...the Metal titan!?" One of the soldiers shouted, "Yes." Mikasa answered,

-Back in the city-

Asura crushed a 2 meter titan underfoot, as he grabbed a 15 meter by the neck, and tore its nape out. Blood was everywhere, and Asura was saving as many human lives as he could at the moment. He then superheated his left arm, and punched a hole into a 15 meter Abnormal and burned its nape. He then breathed fire at a large gang of 2 meter titans. Burning them to ashes, as he moved through the city, he noticed a large boulder that could be moved. (That'll do.) Asura thought, he then gathered his strength and his entire body started glowing red. Asura then ripped the boulder from its resting place and started moving to the gate. "Armin! Send a message to our superiors! Tell them to clear a path for me!" Asura roared, "Understood!" Armin said, Eren's leg had grown back. "Let's go!" He shouted, a few hours later every single soldier was fighting to clear a path for the Metal titan. Mikasa was more than ready to help. As she cut down a 10 meter titan, she noticed the flaming boulder moving to the gate. The titans were thinned out enough that Asura could move. Many civilians were watching him with hope that the Metal titan's plan worked. As if he could feel everyone's hearts beating as one, Asura picked up his speed a bit. (I made a promise five years ago.) He thought, (Fight.) (To be one of humanity's greatest protectors, not it's destroyer. Today, I will make good on my promise...by giving humankind their first victory!) With that Asura roared and without hesitation slammed the boulder into the hole with enough force to burn any titans outside, and fuse the rock with the wall. Nobody could believe it. The Metal titan had sealed the breach. It had driven the titans out of Wall Rose! Many soldiers and civilians cheered as the first victory in humanity's history against the titans, spread like wildfire. Mikasa looked at Asura and saw hope standing in full Metal.

And done! Sorry about bending accepted canon, but I hope it was enjoyable nonetheless. As always comment, rate, and leave advice so I can improve, next time, Asura identifys himself as the Metal titan, and later, the Scout Regiment, along with Eren, Mikasa, Armin and Asura along with the others, run into the Female titan!
