A Shocking Return?! A Warrior of Justice Reborn!

[Moments After the Omega Burst...]

I felt... At peace, I woke up... I saw my Father and those two others from before.

"My son, what are you doing here?" My Father wondered.

I looked at them confused. What did he mean?

"I sacrificed myself to save everyone. I-I knew what I had to do... I'm dead, aren't I?" I told him.

My Father laughed and shook his head, "No, Alyx. The reason why you faded into your Overdrive, was because of that earring you're wearing."

My earring? I guess I never really read the back of it.

"Tanjiro... Nezuko... Tell him what it means." He continued.

So, that's what their names were!

"It means, 'To Protect', Alyx. My master enchanted them long ago when I was alive." Tanjiro explained and Nezuko nodded.

I stood there, motionless, I wasn't sure what to say.

"What that means, Alyx," Nezuko said, "Is that you're alive."

I... I couldn't believe it... I felt tears stream down my face.

I ran over to my Father and I hugged him, "T-Thank...Y-Y-You... D-Dad...!"

I was crying my eyes out. I couldn't believe that I was alive! It was a miracle!

"Your journey doesn't end here, Alyx. You've still got much to do!" Tanjiro exclaimed.

I looked up and saw both of them smile at me. I let go of my Father.

"O-Okay, I understand." I wiped the tears from my eyes and stopped crying.

"I'm giving you the rest of my Overdrive, Alyx. Use it well, my son! We'll be watching over you!" My Father smiled.

"Defeat Tomura Shigaraki! Save your friend's lives!" They all said in unison.

[Two Hours After the Omega Burst...]

My Father gave me all his Overdrive, and I blacked out. I woke up in the same spot I eviscerated Gigantomachia in. I hope I wasn't too late!

I felt Deku's Heat Energy decrease slowly, "Hang on, buddy, I'm on my way!"

In a flash, I flew towards Deku! I didn't even notice how much stronger I felt, what was this? I didn't really have time to think. The only thing I needed to do was act. saw Shigaraki, he was gonna touch Deku! In a matter of seconds, I was to the side of him, and I knocked him away from Deku!

(I.R.P.: Listen to Samuel Kim Music's cover of "Kamado Tanjiro no Uta (Rengoku's Last Smile)" from Demon Slayer: Kimetsu No Yaiba)

"W-Who...?" Deku muttered.

I looked down at him and smiled, tears filled his eyes.

"You've all helped me, in so many ways, now's my turn to help you!" I grinned.

Shigaraki looked like some sort of demon, his skin was completely charred except for some parts of his forehead and his body. I landed back down on the ground with Deku, he was hurt terribly! He stumbled towards something, but I couldn't take my eyes off of Shigaraki to see what he was running to.

"W-Who... In the hell... Are you?" Shigaraki sputtered out.

"You know damn well who I am, Shigaraki! I... I am the voice of hope, defender of justice, and the light that shines upon every single person on this planet. Tomura Shigaraki, I, Alyx Leonidus, have come to destroy you! Your soul has put a negative burden on this world, I can't let someone like you live on any longer!" I shouted.

*THIRD PERSON*

Bakugo looked up towards Alyx as he laid on the ground, tears began to fill his eyes as his mouth was slightly agape.

"Alyx, you really are something else. It disgusts me and I fucking hate what I'm about to say, although I wouldn't ever say it to your face, but you're the strongest person out of all of us. I'm glad that you're around, Alyx Leonidus, you truly are the strongest hero in the world right now. There's just one thing... One major thing that I just can't understand about you. When I told these extras to fuck off when they were gawking about your dumbass Amnesia, I was being kind to you, but that's an emotion to me that signals some kind of weakness. In order to be the best, I can't be weak, but... You, Alyx Leonidus, you somehow make that kindness into strength." Bakugo thought.

Memories of Leonidus flashed through Katsuki's mind, "How can someone do that? How do you go into every battle and even grant the slightest bit of kindness to your enemies? You only seem to get stronger because you aren't truly fighting for fun, neither do you fight against people because of how strong their Quirks are... But you're fighting because you've got something to protect, no... Not just that... You don't fight villains in order to win, you fight in order to be certain that you won't ever lose, in order to keep reaching your maximum power. No wonder you'll kill without hesitation if need be."

Bakugo sat upwards with a smirk on his face, he lightly chuckled as Leonidus stood off against Shigaraki.

"Go on, Alyx Leonidus, you're the only person in the universe who can stop Tomura Shigaraki. I firmly believe... That you ARE number one! I should've recognized that when you first came to U.A., when I was first introduced to you. Give him hell, spare him not the slightest ounce of mercy, but do it in your own way, nobody else's. He's hurt so many people, so just this one goddamn time, don't even think about sharing your kindness with him. If this is my last thought I'll ever have, if I die because I saved my life long friend... Then so fucking be it. Thank you, Alyx, for everything you've done." Bakugo thought once more.

Back at U.A., All Might watched with a smile on his face, Eri hopped up and down with utter joy as tears of happiness ran down her face.

"He's okay! Mr. Leonidus is okay!" She cheered.

Leonidus' Mother and younger sister felt a huge wave of relief wash over them. Liz hugged her Mother as tears poured down her face.

"Thank you... Darren... I love you so much..." She quietly wept.

The violet-blue flower that Liz planted in memory of her brother began to brightly glow amongst the other flowers in the garden. Kariya watched on from his apartment, a smile appeared on his face as he saw his brother, Alyx, standing firmly against the intimidating Tomura Shigaraki. He shook his head as he continued to smile at the TV.

"You're somethin' else, you know that, Alyx? Save the world little bro, keep this place safe like I know you can." He grinned.

In the Seventh Plane, the girl who saved him from death at the hands of the Chainsaw Nomu during the forest lodge incident looked on as well, tears of joy slowly ran down her face.

"Do it, Aly. Make this world right again! I love you so much." She smiled softly.

The entire nation of Japan was sitting on the edge of their seats, realizing that there was a glimmer of hope still left, the light of hope was being cast by Alyx Leonidus himself! Cheers of encouragement rang throughout their homes, tears of happiness were shed all throughout Japan, even from those that Leonidus had fought in the past.

*LEONIDUS P.O.V.*

(I.R.P.: Listen to "Accelerated World" from Accel World)

I darted towards him, with one hit, I sent him flying into a destroyed building. A couple of them actually! I appeared behind him and uppercut him through one of the buildings! As he was in the air, in a flash, I was in front of him.

"Say your prayers!" I shouted.

I hit him with a Dorarara Rush! My fists flew faster than ever before, it honestly kind of surprised me!

"DORARARARARARA!!!!" I roared.

My last fist sent him flying back into the ground. Shigaraki somehow shot out those claws that All For One could do! I dodged through the dozens of them that he was firing at me! I broke a couple of them and threw them back down towards him. They pierced right through Shigaraki! Somehow, he was still going, what exactly is this guy made of? I landed on the ground and he darted in front of me with his hand out.

"Your Quirk... IS NOW MINE!!" He yelled.

"Alyx! Move!" I heard Shoto shout.

His hand was placed firmly on my face. He grinned, but that grin quickly turned into a face of pain.

"Aw, what's wrong," I smirked deviously, "Can't handle it?"

Shigaraki started foaming at the mouth and convulsing. My Overdrive immediately burst out of him; he couldn't handle it at all! He trembled and fell to the ground.

"That's a shame, isn't it? All that power going to your head... Unfortunately, I'm rather amped up for more right now. It's kind of boring if this'll be that easy!" I grinned.

Shigaraki laid there shaking heavily, "Y-Y-You... H-How... D-Da-Dare you..."

"Look at you... Is this really everything you've got? Come on, don't tell me that this is all the great Tomura Shigaraki has in store? You're seriously getting pummeled by a kid? You're fucking pathetic! So much for this All For One bullshit! You're just a fucking joke, hurting the people I love, I've got no care about what happens to you from here on out." I laughed.

Shigaraki suddenly exploded towards me and sent me flying into the ground. Did he just use... Bakugo's Quirk?! No... It must've been something else, it didn't look like an explosion came from his hands at all. I rebounded and rushed after him, I grabbed him by the neck and threw him into a collapsed Skyscraper! As he was sliding down off of it, I quickly charged at him, knocking him back into the building.

"Eat brick, asshole!" I shouted.

I created an Overdrive Whip and wrapped it around his neck. I put my foot on his back, and like a sled, We went down the building! Shigaraki somehow used his decay to propel off the building and into the ground below! I rolled off of him and stood right back up.

"What's wrong? Can't keep up? What a loser! Here I thought you'd actually be a challenge! You're a grown ass man getting beat up by a kid! Get serious already, you damn baby!" I ridiculed him.

I looked down towards the ground and saw my reflection in a piece of glass. My hair was completely up, with glowing blue streaks at the base of it. My eyes were glowing a bright blue and there were lines of Overdrive on my forehead connecting throughout my body. What was this?

"I'm not letting you get One For All, Shigaraki!" I yelled.

"How dare you... Stand in my way... That's all you heroes have done!" Shigaraki shouted back at me.

"Really? What the hell's your problem? Why do you have some sort of grudge against heroes?" I asked.

Shigaraki coughed up blood, "It's because... They don't care about saving people. They only care about the fame they get... The money... I won't let a system like that go on. It needs to be crushed!"

"Good grief... Do you really think that any of the students you decided to lay waste to were going for the fame? Have you ever stopped to think about what the fuck you're doing, like, ever?!" I questioned.

"Of course! You all just decided to get in my way, that's all." Shigaraki grinned.

I walked towards him but Shigaraki held is hand up, "Ah, not so fast. How about... you look around you... Go on..."

"Take a good look around you... Alyx..." Shigaraki smirked.

I stopped and looked around me. Deku was bawling his eyes out and... Bakugo was... I looked over a few feet away, Momo was laid out... S-She has stab wounds on her... Mr. Aizawa w-was...

Shigaraki cackled, "You know... I'm enjoying this... Watching all of you squirm, thinking that you have a chance against me..."

(I.R.P.: Listen to "Virtuous Pope" from Jojo's Bizarre Adventure, this will be Leonidus' Main Theme!)

I didn't turn around to face him. Everyone... Was I too late?

"Before you die... Let me tell you something... I brought Black-Heart here... To kill your Father..." He laughed demonically.

My eyes widened, he... What? My blood began to boil and my breathing became unstable. After everything I seen, I was convinced that this was it. But when he said that he was the one truly responsible for killing my Father, my mental psyche shattered. I didn't give a flying fuck about heroes or villains, all I cared about was tearing that stupid little fucking head off his shoulders. I slowly turned around towards Shigaraki and made eye contact with him. As my Overdrive burst outwards, the ground beneath me completely shattered as I flew towards him. I grabbed him by his face and pushed that damn head of his into the ground!

"URAAAAAAHHHHH!!!!" I screamed.

I pushed his face further into the ground. I threw him into the air and followed after him, I flew up behind him and reeled my fist back.

"RAAAHHH!!!" I roared.

I hit him with an Overdrive Fist, the impact made a crater farther than what I could see! I put both of my hands out and they were fiercely glowing a violet-blue.

"FUCK... YOOOUUU!!" I shouted.

I rained down my Stardust Shoot on him, hundreds of beams shot out from my finger tips and pierced Shigaraki.

"HAAAAAAHH!!" I yelled.

I output more and more beams of Overdrive from my fingertips. Shigaraki was somehow protecting himself from the rest of my blasts. I rushed down to Shigaraki and he fired off a wave of his Decay Quirk at me. I knocked it out of the way and rammed right into him!

"YOU HURT THEM... ALL OF THEM!!" I shouted.

Some primal instinct took over me as Shigaraki tried that extendable claw bullshit again, so I dodged his attack and bit down on his wrist.

"W-What the...!?" Shigaraki muttered.

I reeled my head back and tore Shigaraki's arm off! Shigaraki shrieked in pain, but his arm was slowly regenerating.

A look of fear and anger came across Shigaraki's face, "M-My arm... YOU DAMN BRAT!"

"What's wrong? Lost something you love? You seem to do that a lot, huh, fuckface?" I wondered.

For the first time in my life, I gave off a sinister smile. He knew exactly what I was talking about, and went into a rage!

"Oh, shut the hell up!" I yelled.

As he was screaming at me and charging towards me, I created an Overdrive Whip and grabbed him with it. I slammed him back and forth on the ground until he managed to pierce my right leg with one of those claws. Shigaraki quickly ran up to me and knocked me out of the crater we were in. I landed on the ground hard but I quickly got up. Shigaraki didn't follow me, where was he? I looked back over towards Deku, Bakugo, and Shoto. Bakugo was alive! Shoto froze over his wounds! I wasted no time in heading over to them.

"A-Amnesia... You're...?" Bakugo muttered.

"Yeah, thankfully! We need to finish him off." I nodded.

"But how? He's practically invincible with that regeneration. Even if we manage to blow him up to pieces, he'll just regenerate." Shoto noted.

He was right, he'd just regenerate back to his normal state. As I healed them, I had an idea in mind, and thanks to my Father, Tanjiro, and Nezuko, I had enough power to do it!

"I can distract him while you go and heal anyone that's hurt!" Deku yelled.

Before he jumped off into battle, I gave him some of my Overdrive. I immediately turned my attention to everyone else, starting with Mr. Aizawa! I quickly ran over to Mr. Aizawa, his lower part of his left leg was cut off!

"A-Alyx... Is that you?" He called out.

I put my hand on Mr. Aizawa's left leg, I heard shuffling and sliding noises. Mr. Aizawa's other part of his leg was coming towards us! I honestly had never seen anything so unsettling in my entire life.

"W-Wait! I had to cut it off. I got hit by a Quirk-Destroying Drug there." Mr. Aizawa told me.

I stopped healing him and grabbed the detached part of his leg. Could I somehow get rid of it? I think I could extract it out of his leg if I healed just that part. I started healing that part of his leg and glowing red liquid flew out of his leg and towards a destroyed needle.

I looked at the needle, then back at Mr. Aizawa, "Trust me, I'm just as surprised as you are!"

"Alyx, give him hell, alright?" Mr. Aizawa smiled.

"Yes sir! Also, I may need you to help distract him." I told him.

"Alright, I'll get into position." He replied.

I nodded my head in agreement and zoomed off towards Momo. Luckily, her Heat Energy was still there! It was slowly fading though, but I still had time! I got over to Momo, she looked worse for wear, and she was unconscious. I put one hand on her forehead and the other on her stomach. As I was healing her, I couldn't help but feel as if I was already too late.

"Please, get up... Please!" I urgently pleaded.

Momo slowly opened her eyes and started coughing.

I hugged her, "Thank God!"

"Al...yx...?" Momo croaked.

She put her hand on my back and I felt tears run down my shoulder. I looked at her and wiped the tears from her eyes.

"We're gonna finish this! I'm not really sure how but I've got a pretty good idea." I told her

"How? H-He's practically unkillable!" Momo responded.

I smiled, "It may be something I learned from a manga I read."

"You're serious, right? Now's not the time for fooling around!" Momo wondered

"Yep! Just watch!" I reassured.

I ran back over to Deku, Bakugo, Shoto, and Shigaraki.

Shoto looked at me, "Do you have a plan?"

I simply smiled and nodded. It was time to end this, hopefully this'll work!
