A New Fusion Fighter! (Part Two of Three)

(I.R.P.: Listen to "Will They Fuse?!" from Dragon Ball Super: Broly)

"There's only one way that we can fight him now, are you thinking what I'm thinking?" Alyx asked.

"Yeah, I know, use that Infinite Mode of yours or whatever. Aren't you a Quirk God? Use that instead." Kariya nodded.

"He's using his world's Mikaboshi's full power on top of his, it's not going to cut it, Setsuko was a different story. She wasn't strong to begin with, but we're dealing with another me here! We need to use Spirit Fusion!" Alyx replied.

Right before they could move, Omega fired down a blast at them, the two dodged out of the way but got nailed by some debris. They crashed down by two completely demolished buildings.

"Y-You're kidding me? Why can't you just do that with Mikaboshi like you always do?" Kariya protested.

"He's kind of asleep, and once he's asleep, he doesn't exactly like waking up. Come on! Now's not the time to be arguing, we can't let him get whatever he's after!" Alyx pleaded.

Kariya scowled and rolled his eyes, "Fucking fine! We're ending this quickly, I don't want to stay attached to you for long."

Alpha Omega tossed Oboro aside as Sero latched onto his arm with tape. Aoyama fired off his Naval Laser at maximum power as Sero threw him towards it. Kariya and Alyx both activated their Overdrives before clasping each other's hands.

"This is so embarrassing..." Kariya muttered.

"Oh, shut up, will you? It's not like anyone can see us." Alyx chuckled.

(I.R.P.: Listen to Friedrich Habetler's cover of "Blue Vegito Theme" from Dragon Ball Super)

A pillar of white light erupted in the sky! A figure descended into the sky with their arms crossed. Alpha Omega knocked everyone back with a gust of wind as his attention was averted to the new fighter in front of him.

"What...? Who in the hell are you?" He called out.

"Hmph! We're the Spirit Fusion between Alyx and Kariya Leonidus, or for short, you can call us Karylix! You wanted to use the power of Mikaboshi, so we decided to use a power of our own as well!" He smiled.

"How adorable! You fools think that'll stop me?!" Omega screamed.

He launched an attack straight at Karylix, in response, he let out a small orb of his Overdrive. It split the attack in half with ease and it soared right past Karylix! Omega looked on with astonishment as Karylix let off a cocky grin.

"Don't shit yourself from fear, you're supposed to be some sort of God, right? Maybe you'll actually serve as a warm up for me then! What did you call it earlier? A main course?" Karylix laughed.

"How dare you... You... You dare mock me... I'll fucking kill you for even fathoming the audacity of mocking me! A simple mortal like you would-" Omega fumed.

Karylix sighed and looked away, "Blah blah blah. We aren't interested in this dumbass agenda of yours, could you just shut the hell up for five seconds, you're starting to make all of us tired with all this 'divine' bullshit. You'll probably beat me by boring me to death!"

Oboro looked up at the sight with visible confusion on his face. He blinked a few times before shaking sense back into his head.

"Geez, first off, what exactly have I missed? Secondly, what exactly were they feeding the new gen of heroes back then?" He pondered.

"Trust me, it was quite the treat witnessing it first hand back in the day!" Sero responded.

Karylix landed down on the ground as Omega trembled with even more frustration and anger. He stretched his arms and legs before shadow boxing right in front of Omega!

"There, now I've gotten used to the feeling. Did you seriously just stand there while I did all that? You're fucking kidding me... Alright, get ready to fight, I'm comin' attcha!" He grinned.

Omega shook his head, "You two combined and now believe that you have all the power in the world to stop someone like me? You really are irritat-"

(I.R.P.: Listen to "Be Prepared" from Jujutsu Kaisen)

"FUCKING SHUT UP ALREADY, WILL YA?!" Karylix shouted.

Interrupting his monologue, Karylix rammed an Overdrive Fist into Omega's face, sending him bouncing off the ground.

"Ha! Didn't I just tell you I was coming at you? You must be an idiot to not believe me! Come on, get serious, would you? Stop talking and put your money where your mouth is, jackass." Karylix chuckled.

Omega rebounded and charged right back towards Karylix, the two clashed fists and sparked a bright light on contact! Karylix moved Omega's hand to the side and slammed his fist in his jaw. Omega was pummeled by a quick combination of strikes by Karylix before ducking a strike and sending a vicious knee into Karylix's stomach. He sent Karylix tumbling backwards after detonating a Flash Cannon right in front of him. Omega charged into the air after him, Karylix's eyes shined brightly which caused Omega to halt his pursuit. Karylix's Overdrive exploded out as he entered Gear Five!

"Sorry, I wasn't fighting seriously there for a minute, I just wanted to see how strong you were! Color me somewhat impressed, but I think it's time we really started!" Karylix smiled.

"Don't assume that just because you two mortals have joined together that it means you'll defeat me! You'd be fools for even believing that you can hold a candle to my power! I am a God! You should've taken me up on my offer, Leonidus, we could've been rulers of the universe." Omega scowled.

Karylix yawned and rubbed his eyes, "Uh huh, yeah, alright. Do you mind tucking me into bed too? I'm sure I'll be getting a full night's sleep with your boring ass ramblings!"

"DON'T YOU FUCKING MOCK ME!!" Omega thundered.

Omega roared with anger as he made his way to Karylix. He disappeared then reappeared behind Omega, he sent him down with a chop to the back of his neck, the ground cracked and indented as the area around shook from the impact. Karylix raised his hands into the air, a ball of Overdrive formed in his hands, he aimed it down towards Omega.

"Diamond Buster!" He shouted.

He fired it off and it exploded upon contact with Omega. Through the billowing smoke, Omega retaliated with a large beam of his own, Karylix narrowly dodged the full power attack. Omega created a blade of Overdrive and Karylix did the same, the two darted towards each other, striking and dodging each others slashes. Alpha Omega was caught by Sero's tape right as he was about to slash at Karylix's chest.

"Why you-" Omega raged.

Karylix took advantage of the distraction and blasted Omega into a huge chunk of destroyed building, Sero quickly held him against the piece of debris as Karylix charged up an attack.

"Hey, thanks for the assist, Cellophane! Now, time for the big finish!" He announced.

He put his arms to the side, "Final... Emperor Blast!!"

A huge golden purple blast barreled down towards Omega. His eyes widened with fear as it rammed right into him. It burrowed him into the pavement and finally exploded violently, a huge mushroom cloud shot up into the air, Karylix turned around with his arms crossed. He blew a piece of hair out of his face as he sighed.

"Well, that's that! Here I thought he'd be a decent fight, I guess I just had my hopes up, I'm just too amazing!" Karylix gloated.

His hopes were immediately quashed as Omega's Overdrive erupted into the sky. Karylix turned his head as the heroes regrouped around him.

"How long can you guys stay like that?" Iida asked.

"For as long as needed, this guy ain't letting up anytime soon, knowing Alyx we've got a long way to go before he's done. Looks as if he's ready for round 2!" Karylix answered.

Oboro kept his quarterstaff at the ready, "I know I shouldn't be asking this while a near God-like villain is getting ready to come at us, but what exactly did you two do?"

"Spirit Fusion, you've been dead for quite some time, so I don't blame you for not knowing about it. It's a technique that any Power-Up Quirk user can do with another person with a Quirk classified as a Power-Up type, it combines and magnifies their power ten-fold. Although, in some cases, there are some exceptions to the rule. I'll tell you more later." He briefly explained.

Omega smashed through a plethora of debris to free himself. He tore off his tattered sleeveless black turtleneck as he panted heavily.

"I... Will... Kill all of you... Mark my fucking words you godforsaken mortals... I WILL BATHE IN YOUR SINFUL BLOOD!" Omega exploded.

Omega began to charge up to his full power, everyone but Karylix guarded against the violent winds that were brought forth by Omega. Karylix stood still but matched the pressure Omega was putting out by charging up his Overdrive.

"How will this end I wonder? I'm rather interested to find out!!" Omega cackled.

Right as Karylix charged forward, he suddenly defused back into Alyx and Kariya! They both looked at each other, shocked and confused as to why they separated. Omega couldn't help but laugh at the display of his enemy's confusion.

"M-My hand... It slipped!" Kariya muttered.

"You fools! Prepare yourselves for death at the hands of your God!" Omega grinned.

In a flash, Omega appeared in front of both Kariya and Alyx, he delivered a punch to both of their guts. Kariya and Alyx launched their fists into Omega's face but he didn't move one bit! Omega blasted Kariya away as he rammed an Overdrive Fist into Alyx's face. Iida flew in but was caught by Omega, he used him as a weapon against Alyx, then slammed him hard onto the ground. Aoyama, Oboro, and Sero stood with fear riddled on their faces, unsure what they should do next. Omega grabbed Alyx by the throat and pierced him with an Overdrive Blade.

"You dare sully my name? Once I'm through with you, I'll be moving onto that spawn of yours, Mabel was it? She's holding something that I'll need, or well... That someone needs." Omega smirked.

Omega's eyes widened as Alyx's grip on his arm suddenly strengthened, "I-I... Won't... Let you... Lay... A goddamn finger... On my daughter..."

Alyx snapped Omega's wrist in half, causing him to drop Alyx to the ground, he held his wrist as he looked at Leonidus.

"You people... Piss me off so fucking much... Do you have any idea who's daughter you're trying to kill? I'm not the number one hero for no fucking reason. I'm ending this bullshit, right here, right now. I don't give a shit if you're some sort of God, neither do I fucking care if you might be stronger than me, nobody is going to hurt my family." Alyx fumed.

His Overdrive aura ignited as he entered Infinite Mode, "AND I MEAN NOBODY!! YOU FUCKING GOT THAT, ASSHOLE?!"

He rammed his fist into Omega's stomach, making him vomit blood, one punch to the face sent him flying into the sky. Alyx rattled his fists against Omega at speeds not seen by the naked eye. Omega saw an opening and threw a fist at Alyx, Alyx easily dodged it then sent a shock of Overdrive through Omega's body. Leonidus placed his hand on Omega's face, a huge blast decimated the area around them, Alyx fired off dozens of beams of Stardust Shoot down at Omega. He chucked a Flash Cannon down for good measure, the explosion vibrated the surrounding area. Alyx landed down on the ground and slowly approached Omega.

"Don't you ever... Think about threatening to hurt my family. I'm ending this." Leonidus growled.

Omega coughed up blood as he was on his hands and knees, "P-Please... I-I... m... S-So... Sorry..."

Alyx kept his hand outward with a beam of Overdrive at the ready to kill, his face of seriousness and anger turned to one of surprise as he saw tears fall down Omega's face. He looked back down at the ground as Alyx continued to point his hand at him.

"Go on... Do it..." He mumbled.

"Go home." Alyx spoke up.

Omega looked up with confusion as Leonidus put his hand down. His hair faded back to it's natural brown color and his eyes changed back to blue.

"I'm giving you one last chance, Omega. I'm sure you have at least someone to go home to. Cut your losses while I'm giving you the chance." Leonidus continued.

Alpha Omega's Tomikoa Muteki flashed in his mind, he closed his eyes and smiled. Omega stumbled up to his feet as he very slowly began to fade away.

"I'm afraid he won't let me see her, at least, not in this plane. I presume I've used up my worth to him. Thank you... For allowing me to go out with an excellent fight, Alyx Leonidus." Omega smiled.

Alyx nodded at him, "May the afterlife treat you kindly, Alpha Omega."

"Before I go... Eight Bullets." He continued.

"What? What are you talking about?" Leonidus questioned.

"Do some research, you'll find out. Goodbye, Alyx Leonidus. Thank you." Omega grinned.

Omega finally faded away as the wind carried the dust. Sero, Oboro, and Aoyama quickly ran up to Alyx.

"S-So, did we win?" Sero asked.

"I'm not sure, I guess only time will tell. Let's get this place cleaned up." Alyx answered.
