Leoboshi's Power! A Final Battle Arises! (Part 2 of 5)

*THIRD PERSON*

(I.R.P.: Listen to "Final Battle" from Super Dragon Ball Heroes)

The two warriors stared each other down, Leoboshi held a smirk on his face as Setsuko snarled. The air was an eerie calm, both of them waited for the other to make a move, or even look as if they were making a move. Leoboshi tilted his head to each side and blew upwards to his hair. A single strand started to slowly fall down out of the sky. As soon as the strand passed Leoboshi's feet, the fight was on! They locked eyes once more, Leoboshi lightly chuckled at her. The two collided fists, sending a huge shockwave booming throughout the sky! The two zipped in and out of the air, colliding against each other with forearms, kicks, headbutts, and strikes. Leoboshi eventually caught Setsuko with a deadly uppercut!

"Ha! This is getting fun; this might actually count as a warm up after all!" Leoboshi laughed.

Setsuko shrieked at him before launching an assault of Rivet Stab tendrils at him. Leoboshi darted away from them, ducking and dodging through each one to get to Setsuko. He fired off a huge blast of Overdrive that sent Setsuko into the riverbed below! Orbs of blue light surrounded his arms and began to rotate around them.

"DIVINE WRATH!" He shouted.

The orbs fired onto the riverbed and pelted Setsuko dozens of times! Leaving holes and impact marks on her body, she was a bloody mess as she rose from the riverbed and towards Leoboshi. She was met with a huge Overdrive Fist from Leoboshi sending her flying backwards in the air. He grinned at her before multiplying himself using his afterimage technique. The afterimages rushed her, taking heavy shots at her before disappearing, Leoboshi had completely charged up a full power Carving Star Blast and was coming right for her!

"TAKE THIS! CARVING STAR... BLAST!!" He roared.

Using his full power, Leoboshi drilled the Carving Star Blast attack into Setsuko! It burrowed her into the ground below, leaving a huge blast mark in the dirt. It ended with a violent explosion of bright purple light and smoke billowed into the sky. Leoboshi held his hand out and closed it, setting off an explosion of several Flash Cannons an afterimage put behind her back! As the explosion finally died down alongside the smoke, Mikaboshi and Alyx defused.

"Phew! That was a good one!" Alyx smiled.

"Indeed, another one bites the dust, as they say?" Mikaboshi agreed.

Alyx held his fist out and Mikaboshi responded with a fist bump. There was a thunderous boom followed by a flash of purple and black light in front of them. Alyx stood in his fighting stance as the light faded away. Setsuko was still alive after taking all of those attacks from Leoboshi!

"Hmm... She's rather resilient, this doesn't look good." Mikaboshi noted.

"Y-Yeah, this doesn't look good at all." Alyx fretted.

The wounds on Setsuko began to regenerate, her eyes were filled with nothing but rage and malice. Setsuko slowly made her way towards Mikaboshi and Alyx.

"Y-You... You won't... Ruin my plan... OUR plan..." Setsuko fumed.

She held her hand out towards the two, right before she could unleash an attack, a green blur appeared right behind her.

"MANCHESTER... SMAAASH!!" Izuku yelled.

He drove his foot right into the back of her head, sending her violently crashing down into the ground below.

"Hey, nice save there!" Alyx complimented.

"Thanks! And thank you for stalling, how's it coming?" Midoriya replied.

"Not good, she's regenerating every attack that I throw at her. She isn't human anymore, I honest to God, wholeheartedly mean that." Leonidus told him.

Alyx looked down at the ground where other Pro Heroes were taking on Setsuko.

"That smell she's giving off... The way she looks... I don't know why I didn't see it before but... Setsuko's a demon in every sense of the word. The only thing that can stop her now is the Nichirin Blade I have on me. She must've built some sort of immunity to sunlight as well, which that doesn't exactly bode well for us either." Alyx continued.

Izuku looked up at Alyx in disbelief, "A demon...? Do you mean like you?"

Leonidus looked up and nodded at him. Izuku began to sweat as he's seen the full strength of a demon before, thanks to Alyx. Leonidus grabbed the hilt of his sword firmly and smiled.

"Let's go save the world, eh? Mikaboshi, you can help out too, we're gonna need all hands-on deck!" Alyx grinned.

They both nodded and followed Alyx down to the surface. He landed on the ground directly behind Setsuko. He quickly pulled his sword out and slashed right through her arm using his Water Surface Slash.

"Be careful! You can't harm her in anyway, she'll just regenerate it, leave the damage to me!" Alyx shouted.

He boosted himself off a rock and spun around, "Eleventh Form, Jetting Water Geyser!"

As he spun, water surrounded him, creating a sharp point that barreled into Setsuko! He drove her into the ground before being pushed back by a huge gust of wind! He hit the ground hard but got back up.

"M-Momo, can you make any sort of poison or anything involving wisteria?" Alyx telepathically asked.

"That I can, darling! Give me a moment, it'll take some time, I'm assuming you're gonna need a lot?" She responded.

Alyx dodged a kick from Setsuko, "Yeah! Quite a bit!"

"WHY WON'T MY ARM GROW BACK?!" Setsuko exploded.

"It's because I don't want it too, that's why! Just give it up already! Let Fa and Mee go!" Alyx yelled.

"If I let her know about my sword, then she'll be trying to break that instead of trying to kill me. Great Grandpa and the Hashira can help me, but for how long?" Alyx thought to himself.

Leonidus looked over at Laura who was going to be in the crossfire of Setsuko's Black Lightning attack! The ball shot out towards her, Alyx dove towards her, taking the attack himself! He wrapped his arms around her as the attack sent them flying away from the others. He slammed into a tree back first, preventing Laura from getting hurt.

"Alyx! Thank you, are you okay?" Laura worried.

Leonidus used his sword to help himself up, "Y-Yeah... I'm... I'm fine. Listen, you need to stay back from her, alright? I'm not losing you again."

"O-Okay! I will!" Laura nodded.

Alyx gave her a kiss before rushing back towards the battle. Setsuko had multiplied in size; she had another pair of arms protruding out of her back. Shoto sent a blaze of fire into Setsuko, burning her skin, but it still didn't make her waver. Her fist that flew towards Shoto was met by Alyx's blade! He blasted her back with a one-handed blast of Overdrive. Alyx clutched his chest and held his sword with one hand.

"Shoto, I think I have an idea. It might just work! It's a technique I've been practicing for the past few years now, I haven't told anyone about it" Alyx told him.

"Wait... You don't mean...?" Shoto wondered.

Alyx looked over at him and smiled. Shoto shook his head and slightly smiled back.

"If it'll make an opening for us, then do it. I'll be at the ready." Shoto muttered.

Leonidus took off towards Setsuko after Todoroki shot of large icicles at her, she took them head on without problem, then Alyx used his afterimage technique as he got closer to her. He let off a shit eating grin as he pulled a shirt off of him as he activated his Overdrive.

"How about this, cutie? Leonidus Secret Technique!" Alyx winked.

The afterimages cast Doe Setsuko's image of utter perfection! The others stood there dumbfounded at what Alyx just did.

"Y-You're serious, right? Did he just use that technique... When the entire world is in danger?!" Mina thought to herself.

Laura watched on with delight, "I think I just entered heaven. Yeah, this is heaven alright!"

Setsuko was firmly transfixed on Alyx and his after images, Izuku burst through the smoke and mirrors, he delivered a Detroit Smash that was coated in wisteria oil! She flew backwards as the left side of her face began to burn and melt.

"That actually worked? Sweet fucking God almighty..." Aizawa muttered.

Setsuko's back arched completely backwards as she stood back up. Her teeth and ghastly grin became much more visible with the lower left side of her face slowly deteriorating.

"That's just one of the tricks I've got up my sleeve, idiot! I've got more ideas in my head that what you can count!" Alyx shouted.

"Interesting... Even though you've sustained a couple broken ribs, you're still going... How long can you last, I wonder?" Setsuko smiled.

Her freakishly long tongue licked her lips and bloody face. Mineta watched on with widened eyes. He blinked a few times before shaking his head.

"That was creepy... And kinda hot." Mineta remarked.

Leonidus unsheathed his sword and prepared to strike. From the sky, a golden colored blast rained down onto Setsuko, creating a huge impact crater! Alyx looked behind him and smiled.

"K-Kariya!" He beamed.

Kariya held one hand out, steam rose from his palms, he grinned back at Alyx. He landed down next to him and Annie joined them. Kariya and Annie activated Gear Five alongside Alyx.

"Huh, we haven't fought together in a while. Let's give her hell for old time's sake!" Annie told them.

Kariya and Alyx nodded at her, the Leonidus siblings darted straight towards Setsuko. Alyx held his sword up high and struck the extra arms on her back. Kariya wrapped an Overdrive Whip around Setsuko's neck, Annie wrapped it around her torso, the two began to pull in opposite directions! Bakugo came flying in from above. He pulled the pin on one of his improvised grenades and chucked it down at Setsuko's feet.

"EAT THIS SHITBAG!" He roared.

The grenade exploded, but with a special effect, it detonated with wisteria oil inside! It began to burn Setsuko who screamed in agony. Parts of her body began to melt as she tried to struggle out of the Overdrive Whips holding her in place. She let of a high-pitched shriek that shattered the whips and sent everyone flying backwards. Debris smashed into Leonidus and the others from her vicious attack. Alyx slammed against a stone wall that held an outpost station. He pulled himself out of the wall and collapsed to the ground, gasping for air. He looked over to his right, Momo and Kariya were alongside with him. To his left, Izuku and Katsuki.

Doe flew into the air and faced Alyx, using up nearly all of All For One, she generated a dark ball of energy. It covered the sky almost entirely, everyone watched on in horror as they were witnessing their inevitable deaths. Mikaboshi phased out of Alyx and stood in front of him. He looked back behind him and gently smiled.

"Alyx, thank you. Thank you for showing me what life really is." Mikaboshi smiled.

"W-What...? What are you...?" Alyx questioned.

His eyes widened, "N-No, you can't! You..."

"If I don't do it, Alyx, then who will?" Mikaboshi asked.

Alyx clenched his fist and grit his teeth, his lip began to quiver as he realized what Mikaboshi was about to do. Mikaboshi knelt down and gave Alyx one last hug.

"I love you, my friend." He whispered.

Alyx wrapped his arms around Mikaboshi and held him tightly, tears began to pour down his face.

"P-Please... Don't go! There has to be another way! There has to be!" Alyx pleaded.

Mikaboshi pulled Alyx off of him and stepped away. Leonidus tried to follow but was held back by Momo and Izuku. Mikaboshi started to fly towards the ball of energy that got closer to them.

"MIKABOSHI!!" Alyx's cry echoed as he reached out his hand towards him.

"Alyx, you've taught me the many virtues of life, and what mortals can do with them. For that, I can't thank you enough. So, in order to preserve that peace, I offer myself in exchange. I'm sure you'll understand in due time, my friend, as to why I chose to do this. Alyx, save the world, save all of your friends! No matter the cost, no matter what you have to do!" Mikaboshi relayed to him.

Mikaboshi stared at the ball of dark energy as it approached him. He spread out his arms right before it hit. Alyx watched on and cried out his name once more, Mikaboshi closed his eyes and took in a deep breath. The ball of energy got closer and closer to him. His glow began to intensify as the attack began to reach him. Right as it hit, Mikaboshi opened his eyes, which shined fiercely! He began to absorb the attack that Setsuko threw at him. He grit his teeth and tightened his fists. He gave one last look back at Alyx and smiled.

Alyx, become the greatest hero you can be, got it?! Remember what she told you, always smile, no matter what stands in your way! Don't you dare forget it, don't you dare give up, Alyx!!" Mikaboshi shouted.

He returned his gaze to the gigantic ball of energy before him. It slowly became smaller and smaller, Mikaboshi's hands slowly began to untighten. Alyx tried to break free from Momo and Izuku's grasp but he could barely move at all himself. Momo held him close as he cried out Mikaboshi's name once again. The ball of dark energy had been completely absorbed by Mikaboshi!

"No... Impossible! He... How did he...?!" Setsuko fretted.

Mikaboshi's glowing body began to dim as he fell slowly out of the sky. He softly smiled and closed his eyes. Mikaboshi slowly faded out of sight and the entire area grew quiet. A ray of light shined down onto Leonidus, Yaoyorozu and Midoriya. Alyx tightly clutched the back of Momo's hero costume as he cried into her shoulder.

"Amatsu... Thank you... Thank you for everything..." Alyx thought to himself.

The feelings of rage and sorrow were beginning to build up inside of Alyx Leonidus. Momo and Izuku both got up and readied themselves.

"Come on, we need to let Alyx rest, let's go! Once Kariya wakes up, he'll be able to heal him. Right now, he's our top priority!" Yaoyorozu instructed.

Katsuki, Izuku, and Momo rushed back into battle, leaving Alyx alone with his thoughts. He stumbled up to his feet, tears still flowed down his face, but he made no noise. He looked down at the ground and stared at the dirt below.

"Mikaboshi, it's all my fault. I let you die because I didn't use my full power when I had the chance. I could've saved you if I had just used it, even if I died. W-Why... Why did it have to be you?! Why wasn't it someone like me? A coward that hid behind a mask for so many years shouldn't even be on the same dirt as everyone else. You were my first friend that I ever really made, although I was scared of you at first, you never deserved any of this. You deserve a life worth living, you didn't need to sacrifice yourself!" Alyx thought once more.

He closed his eyes, not only did his life flash, but so did his memories with Amatsu Mikaboshi. The battle raged on in front of him, Pro Heroes and his friends struggled against the somewhat weakened Doe Setsuko. Images of Momo, Izuku, Katsuki, Kirishima, Kaminari, and others flashed inside of his mind as well. He felt someone embrace him warmly. It soon faded away as he clenched his fists. The air turned cold and the wind started to pick up. The battle slowly stopped as the feeling began to hit everyone. Setsuko looked around to try and figure out where that feeling was coming from.

Doe looked over at Alyx, the area around him was slowly swirling the debris around him. His Overdrive sparked out of the scar on his left eye as his body slightly twitched and trembled out of anger. Eraser Head and Midnight looked at each other before smiling. The entire field was transfixed on Alyx, his demeanor, and what was about to happen. The wind stopped and silence followed afterwards. Setsuko tilted her head with confusion.

"What...?" She muttered.

"I... Hate... You..." Alyx retorted.

There was total silence on the battlefield. The debris around stopped moving as it finally settled next to him. Then, a pillar of Overdrive enveloped the entire east and northern parts of Japan! It could be seen all across the world! Doe looked on in utter horror as she began to think that this was her end. Alyx floated upwards, his body completely covered in Overdrive.

"DOE SETSUKO. I. WILL. ENJOY. HEARING. YOU. SCREAM. FOR MERCY." Alyx thundered.

His eyes flared out a bright white as the entire area shook and rumbled! The Earth between Alyx and Doe seemingly uprooted, sending Doe into the air with Alyx! A gigantic fist came crashing down onto Doe, but it had no effect on the surrounding heroes! The glowing pillar of Overdrive was then absorbed back into Alyx, revealing his luminescent blue being!

"H-Holy shit... T-That's... He's a Quirk God!" Midnight exclaimed.

Everyone looked up at the sight of awoken godhood above them. Glowing and pulsating red on Alyx's torso was the design of his hanafuda earrings. The familiar 'V' like symbol was marked on his forehead. He intently stared down Doe Setsuko with his cold, fierce and soulless eyes. The entirety of the heroes watched on, stunned and in disbelief at the form Alyx had took. Kaminari stood next to Yaoyorozu and tapped her on the shoulder.

"So, like, we're really gonna have to have a talk when we get home." Kaminari told her.

"Y-Yeah... That we are." Momo agreed.

Leonidus had finally reached the form Chiyoko Kamado told him about! Finally, with Alyx reaching the ultimate level of his Quirk, nothing can stand in his way! How would Doe Setsuko hold up against this fearsome version of Alyx Leonidus? Has the tide finally changed in the heroes favor due to Leonidus' anger?
