Yang was currently sitting in the Ballroom with S/N, watching as he crawled on the floor, playing with Eri

Yang: You two having fun?

Eri: Mhm, he's a baby but he's stronger than me!

Yang: That's no surprise, it is Y/N's son after all...

Yang then gave S/N a few head pats, causing him to laugh playfully as she looked through a window and began to think about you

Yang: Speaking of, I wonder wha your Father is up too...

Meanwhile

A wasteland was all that remained of the woods that you were previously in, the sounds of a desperate battle could be heard in the distance as the moon had turned bright red

Midoriya, Issei, Ruby, and Akko could all be seen attempting to hold you off, but to no avail, even with all of them at once, before your power, the were nothing

Ruby: Y-Y/N! You're better than this!

Ruby then leaped away and avoided a large crimson Ki blast as it exploded in the distance, everyone different spots as you grinned

Y/N: Hehehe..."You're better than this"...I don't know what you're talking about, this is who I am! Ruby!

Midoriya: Y/N! I know that you're in there! Regain control!

Y/N: I assure you, I have 100% control over my own body...but now all I feel...is the untameable urge to destroy!! STARTING WITH ALL OF YOU!!

All of a sudden you leaped in the air and charged towards Issei with your fist reeled back, Issei just barely avoiding the attack alive as your fist smashed into the ground, creating a large crater below you

Ruby: How do we deal with this?! I don't wanna hurt him!

Akko: It's not like any of us can!

Midoriya: I might have a shot...he's trained me...

With that Midoriya decided to cut loose, rushing towards you with his fist reeled back as he screamed

Midoriya: 100% DETROIT SMASH!!!

Midoriya's super powered fist suddenly smashed into your face, causing you to go wide eyed as you went flying back, crashing into a boulder in the distance

Midoriya: I'm sorry, Y/N...I know that you'll understand...

Akko: Yeah! That's it! You can do it!

All of a sudden you bolted right out of the boulder and rushed Midoriya, ready to strike him as you approached him at maximum speeds

Y/N: Ah, Little Deku, I must say, to see that you can't even do any decent damage...I'm disappointed...

Before Midoriya could even respond you dug your fist directly into his gut, twisting your fist as Midoriya gagged and coughed up some blood

Everyone else went wide eyed as Midoriya went skidding across the ground and crashed into a dead tree, you then looked at the remaining three as you smiled wickedly

Y/N: So, which one of you is next...?

Issei: Tch, there's no use in holding back now!

Y/N: Bring it, Red Dragon!

Issei then growled as he activated his boosted gear, beginning to go through a familiar transformation as his boosted gear began to rapidly boost his power as massive wings then spread from his back

BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST

JUGGERNAUT DRIVE!!

Y/N: This old trick again...? Don't make me laugh!

You suddenly rushed towards Issei as his transformation was complete, letting out a loud roar as the two of you threw a punch, clashing fists as the entire battlefield shook

Akko: I didn't know he could do that...!!

Ruby: It's kinda scary...but it's effective for the most part...

Issei then felt the bones in his arm shatter as your punch was too powerful for him, causing him to scream in pain as you grabbed one of his rings and tossed him away

Y/N: Pathetic!

You then looked towards Ruby and Akko as Issei landed in a large crater behind you, both girls felling nothing but fear as you grinned evilly

Y/N: You're all pathetic!!

All of a sudden you were hit by a fireball from behind, this confused you as a voice called out to you

???: Hey Jackass!!

You then turned around and to your surprise, saw Luffy, Natsu, Meliodas, and Naruto all standing there ready to fight

Y/N: Tch! Look! More blood to taint this dead forest with!

Akko: Who are those guys...?!

Ruby: They helped us a while back with Ark...but how did they get here...of course...Kalasha must've summoned them and sent them here...

Natsu: Wait...is that Y/N?!

Luffy: What happened to him?!

Ruby: We don't know!

Meliodas: Whatever happened...we've gotta snap him out of it!

Naruto: And it's not just us either!

Naruto then pointed behind him to see two more people, Tanjiro and Yugo who had accompanied them as well

Y/N: Even more!

Luffy: I'm going in!

Natsu: Hold on a sec—

Before Natsu could even finish, Luffy dove right in, reeling his fist back as it stretched far behind him

Luffy: Don't worry, Y/N! I'll fix you! GUM GUM...

Luffy's arm then stretched all the way back as his fist moved towards you at high speeds, causing you to grin

Luffy: PISTOL—

You suddenly appeared right in front of Luffy and elbowed him in the stomach, causing him to gag as he went flying back

Meliodas was the next to attack, appearing behind you with his blade ready to slice

Meliodas: HA!

Meliodas the went and swung his blade as you caught it with one hand before pulling him in and kicking him in the face, sending him flying back

The next thing to happen was a shiny blue portal that belonged to Yugo, but it wasn't him who came out, but Tanjiro who came flying out instead as he swung his blade at you

I'm return, you formed a blade of Ki in your hand as your blades clashed, with you still smirking more than ever

Tanjiro: Why are you doing this, Y/N?! This isn't right!

Y/N: Tch! There is no such thing as doing the right thing! I DO WHAT I WANT, AND THS IS WHAT I'M GONNA DO!!

All of a sudden your blade of Ki extended and pierced right through Tanjiro's chest, followed by you redirecting his own sword towards his heart and impaling him with it

This caused Tanjiro to gag a large amount of blood as you then kicked him off of your blade

Eye-Catch

Eye-Catch

Meliodas: Crap!

Natsu: H-HE JUST KILLED HIM!!

Y/N: Of course! The Strong Shall survive and the weak shall perish, that is truth!!

Ruby suddenly appeared behind you with crescent rose ready to swing and slash you as she closed her eyes

Ruby: I'm sorry, Y/N!!

She then took a swing at you to which you quickly turned around and grabbed the tip of her blade

Y/N: This thing always annoyed me!

You then punched her beloved crescent Rose as it snapped in half, she gasped and went wide eyed at this as you then kicked her away, sending her crashing into a tree

All of a sudden a large amount of smoke began to emit from your left, you looked over to see that Luffy had changed to a large form

Luffy: GEAR FOURTH!!

Y/N: Wanna test your luck, Rubber man...?

Luffy then gritted his teeth as he rushed towards you at high speeds, as his fist retracted into his arm

Luffy: GUM GUM...KONG GUN!!!

Luffy then launched his attack towards you as you simply blocked it with one arm, causing a massive amount of wind to blow

You continued to grin as Luffy struggled heavily to push you, with you speaking up

Y/N: This is nothing!

Luffy suddenly felt a blade of Ki piece through his chest as well, everyone going wide eyed as you swung the blade, throwing Luffy away as he landed in a body of water

Yugo: LUFFY!

Natsu: Dammit!! FIRE DRAGON'S ROAR!!

Acting quickly, Natsu then unleashed a massive blaze of red and yellow flames towards you as you looked and smirked

Y/N: Heh...

You then aimed the pain of your hand towards his flames before firing a massive beam of red energy towards him

Your blast completely overtook Natsu's flames as he went wide eyed, he was about to do something else when you suddenly appeared behind him and grabbed him by his face, holding his mouth wide open

Y/N: ENJOY YOUR LAST DINNER!!

Natsu attempted to free himself from your grasp but failed miserably as he suddenly was fed your Ki blast which he was forced to swallow whole

You then leaped away while cackling as Natsu was then exploded into bloody pieces soon after, making everyone go wide eyed one again

Akko: H-He's killing everyone...!!

Meliodas and Naruto then appeared in front of you as they both prepared themselves to hit you with a coordinated attack, however, this is when you decided to take the battle to the next level, ascending to Super Saiyan God

Y/N: Allow me to show you just how outclassed you are!!

Meliodas then received a barrage of swift punched to all of his pressure points, paralyzing him as Naruto appeared behind you

Naruto: RASEN—

You then interrupted the nine tailed ninja as you forced your fist fight through his chest, on the other side, Akko had witnessed how you had ripped out his heart, all she could do was stand there in fear as tears ran down her face

Akko: ...S-Stop...

You then turned around to Meliodas as you then began to speak to him, but he was having none of it considering how angry he had become

Y/N: I'm aware that you have more than 1 heart...and if I simply kill you, you'll only come back...so allow me to send you off with a permanent parting gift!!

You then aimed your palm towards him as Meliodas could only say one thing before meeting his demise

Meliodas: Don't—

Y/N: HAKAI!!

Akko watched as Meliodas was then reduced to literally nothing as his remains faded away into thin air

Y/N: Tch...you're all so pathetic...now the only two that remain...are Akko and Yugo...

Akko: Run!!

With that Akko grabbed her Broom and flew off as Yugo disappeared into one of his portals, as you smirked and followed, leaving Issei and Midoriya there to die

Y/N: A chase? So be it, enjoy your last moments alive!!

Akko and Yugo then heard the sounds of a Ki blast charging behind them, both of them going wide eyed as you then unleashed a massive barrage of blasts towards them

Akko heavily struggled to avoid each blast as Yugo was caught in one of the blasts, disintegrating him as Akko was the only one left

Akko: Why?! Why are you doing this?!

Y/N: Why? Why?! Because I simply want to! My Goal is to destroy all life, and that goal I shall attain!!

Eventually, Akko had made it back to HOH, not even intending to as she went wide eyed in regret

Akko: I lead him straight to the academy...what have I done...?!

Meanwhile, Kirishima, Bakugo, Rias, Diana, and Blake were all hanging out outside when they could see Akko flying back, covered in wounds

Akko: G-Guys!!

Rias: Akko?

Kirishima: Hey you're back! How did the mission go?

Akko: IT WENT HORRIBLY WRONG!!

Diana: What? Why?

Akko then turned around as you were approaching the academy at high speeds, revealing yourself as everyone went wide eyed

Y/N: I FOUND YOU!

Kirishima: Hey Y/N what's—

Kirishima was then interrupted as you flew right through him, slicing him in half as his upper half fell right off, catching everyone b surprise and even causing Diana to gasp

Rias: KIRISHIMA!!

Bakugo: What the hell happened?! Why's Y/N doing this?!

Akko: I DON'T KNOW!!

You were about to blast the whole group of students and finish them off when a voice suddenly stopped you

???: That's enough, Y/N!

You then stopped in your tracks as everyone was now watching with widened eyes, looking behind you to see Goku and Vegeta ready to take you on

Y/N: Goku...Vegeta...

Goku: What's happened to you, Y/N?! You're killing people left and right! We sensed it!

Y/N: Nothing's happened, I am still me!

Kalasha: He's been corrupted by an Akuryo Phantom...

Everyone then looked to see Kalasha in sky, hovering down as he landed on his feet and faced you

Blake: So what? His being controlled?!

Kalasha: No, this is different from mind control, he is still technically himself, he knows what he is doing, he is choosing to do this...Akuryo Phantoms don't hit the mind...they hit the soul...

Y/N: Indeed! I have been made better! Thanks to that phantom! And now I shall destroy ALL OF YOU!!

All of a sudden you began to emit a massive crimson aura that spread up into the sky, the whole sky turning dark crimson as everyone watched in shock, your hair went crimson as well as you let out a heavily distorted roar

Y/N: HAAAAAAAAAAAA!!!!!

Y/N: Prepare for a battle like nothing else, and enjoy your last moments of the living realm! THIS IS MY CRIMSON ECLIPSE!!
