Another Threat

"Get out of here, kid. You've done enough." Hametsu told Leonidus.

Leonidus nodded at him, the trio ran off as Hametsu cracked his neck, preparing to fight.

"You're the guy with that Invincible Quirk, right? You're obviously insanely strong right off the bat! What's your name?" Hametsu grinned.

"None of your business, freak. You Villains are all the same, disgusting people that deserve to die!"

Hametsu's face turned sour as he darted towards Fuhai, chopping down on both of his traps. Fuhai went to lift his arms up but couldn't, a numbing sensation filled them instead. Hametsu spun around in the air, whacking his foot against Fuhai's jaw multiple times. He planted his foot on the back of his head, shoving it into the concrete below. Hametsu stood on the back of his head, glaring down at Fuhai with disappointment.

"Seriously? You left yourself open that much? Pathetic, maybe you weren't as strong as I thought."

Hametsu heard more people coming towards him, he sighed as stepped off Fuhai and he put his hands up, only for them to run past him to Fuhai. Mirko grabbed him by the scruff of his neck, smacking him around a bit.

"Are ya fuckin' kidding me?! What in the hell is wrong with you?" She roared.

The heroes scolded and reprimanded Fuhai for his actions. Kasai and Hametsu just so happened to lock eyes with one another. An extremely awkward silence followed as they stood there.

"I still don't forgive you for your actions on that farm, you know!" Kasai beamed.

"And I don't care!"

Meanwhile, Momo, Alyx, and Laura landed down in front of U.A. High, seeing a boy trying to get into the school.

"W-What?! What do you mean I'm not in the database? Mr. Aizawa, you don't recognize me?" The boy panicked.

"I've never seen you before in my life, besides, I don't understand what you meant by 'You look younger'."

Leonidus approached the two, "Hey, what's going on here?"

The boy stopped and slowly turned around, seeing Leonidus and Yaoyorozu standing behind her.

"Woah... Mabel's Mom and Dad? You two look younger!" He wondered.

"Huh? Dad? I don't have any kids! At least, I hope not!"

"Um... W-Well... I'm her friend but like... Or well, I guess not from here!"

"I'm assuming you got sucked into some sort of storm that sent you here?"

The boy gave him a curious look, "Yeah, how'd you know?"

Leonidus briefly explained that the storms were popping up more frequently after he and Izuku Midoriya defeated Tomura Shigaraki. Laura then informs her that the same thing had happened to her, and she was from a different reality.

"Okay, okay, I see. My name is Ishimoto Midoriya, it's a pleasure to meet you guys... Again? This is so weird... I can't wait to tell Mabel when I get back!" Ishimoto introduced herself.

"I knew we'd have a daughter, Alyx."

Leonidus looked over to see Momo's smug smile plastered on her face as she glanced at him. Shota shook his head as he opened the gate, Leonidus walked with Aizawa as the other three conversed about the situation.

"So, this is quite the dilemma we've gotten into. Any ideas?" Shota wondered.

"Hmmm... I've got a gut feeling I know who's behind all of this. Stand back for a moment."

Leonidus began to open up a portal to the Seventh Plane, the two looked inside, the Plane had been morphed into a cataclysmic purple dimension, Yaoyorozu and the others made their way to him as he stepped inside.

"Holy hell, what happened here?" Alyx questioned.

"Be careful, darling!"

"I will-"

The portal suddenly closed on Alyx, he froze, expecting something to attack him. Leonidus looked around to see that there was nothing there.

"L-Leonidus...? Is... Is that you?" A voice called out.

Alyx saw a beaten, bloody and near death Omoikane. He was propped up against the bodies of the other Gods.

"Mr. Omoikane! What happened? Are you alright?"

"Onryo... H-He... He had... Betrayed... Us... The... The cube..."

"Cube? What cube? What did he do?"

Omoikane grabbed Alyx's hand, "Y-Y-You must... Stop him from... Distorting reality... Please... F-For... Amaterasu..."

The life finally faded out of his eyes, his hand went limp and cold, Leonidus closed Omoikane's eyes before looking over towards the partially destroyed manor. He made his way towards the manor, particles of the Plane floating by him. Alyx entered the manor, noticing the various spirits that littered the ground, certain spots of the manor were still lit with violet embers. As he approached the main chamber, a book with charred marks on the back and front was in the doorway. He knelt down to see what it was, the book had been more of a journal that described the properties of the cube. He read through the journal, looking over key pieces of information.

"The Reality Crystal... It's power is unmeasurable. It powers the entirety of the Seventh Plane, without it, the entire Plane would collapse? Someone's used it before? Unlimited power... Only way to be stopped is to destroy the controller... Destruction of the crystal would wipe out all life across the multiverse..." He read aloud.

Leonidus kept the book with him as he hurried out of the manor, as he exited the main chamber, he was suddenly frozen in place.

"And where do you think you're going, Leonidus?" Onryo asked.

He appeared right in front of him with the Reality Crystal in his hands. A dark purple aura surrounded Alyx, lifting him up into the air, Onryo shook his head and grinned at him.

"I can't have you ruining the fun, can I? You don't understand the plan I have in store for all of you, a one world society where no one is stronger than me! With the Reality Cube, I can finally reclaim what was once mine, if those impudent Gods hadn't left me in Hell!" He continued.

"Y-You... This isn't right! You don't understand what that thing is capable of! Without it being in the Plane, it'll kill everyone, including you!"

"You don't think I knew that already? Only a fool would allow such a fate to transpire, but this crystal, it's rather paradoxical. It may wipe out all of existence, but using it's power, I can prevent that from ever happening. Now... How about we get this thing started?"

Onryo opened up a portal behind Leonidus, "ONRYO!!!"

He shot Alyx through the portal, closing it as he entered, Leonidus went through different realities until he finally fell unconscious. In this new reality, a dimensional storm opened up right above U.A. High's dorms, Leonidus was shot out of it, crashing into the ground. As his vision was still blurry, he saw three familiar faces standing over him.

"M-Mina...? Jiro...? Denki...?" He croaked.

"Huh? Who's that?" One of them responded.

Leonidus sat up, rubbing the back of his head, his vision finally became clear. He saw that they were his friends, but...

"I kinda figured there'd be a reality like this one." Leonidus lightly chuckled.

"What are you talking about, Alexis?! Did you get hit with a Quirk or something?" Kaminari wondered.

Leonidus got up and brushed himself off as the rest of the class made their way outside.

"The fuck is goin' on out... Here?" Bakugo fumed.

Alexis stepped forward with awe, "No way... Y-You're... You're me but... I can tell you're super strong!"

"Hee hee! As much as I'd like to explain myself, I'm... Or well, we're all in a bit of trouble, let me explain..."

Leonidus proceeds to tell his peers about the Reality Crystal, how there are dimensional storms popping up all over because of it, and how Onryo plans to use it to try and merge every single reality into one. He shows them all the book he managed to keep from Onryo.

"I have to get back to my reality, the only issue is, I can't exactly do that since I don't have a clue how to do it."

"I-I uh... I might be able to help with that." Alexis spoke up.

"Yeah! She used to go to different dimensions and stuff! She's brought us back some cool things!" Izumi Midoriya added.

"Wait, you've done that? Isn't that against the rules of Reality and Time? Hasn't Amaterasu told you that?"

"Amaterasu? Who's that?"

Leonidus crossed his arms, "I see... I guess I forgot how different realities can be..."

"There's just one thing though, if I do that, I can't come back for sometime and I'll be stuck with you. I really don't want to leave my friends, not like last time."

Leonidus could tell that his counterpart didn't want to discuss the incident, he nodded at her, sparking his Overdrive around his hand.

"Could you teach me how? I'd really appreciate it." Alyx smiled.

She nodded at him, Alexis opened up a portal to her version of the Plane, the two walked through as the portal closed behind them. As Alexis walked ahead of him, Alyx grabbed her arm, she already knew what he was going to ask.

"I lost him. I lost Yaoyorozu thanks to Shigaraki, I wasn't there to help him, I got stuck in a different reality. That's why you didn't see 20 of us like you would in your world. I got sucked into one of those things too, it's what made me lose the person I loved most." Alexis confessed.

Leonidus envisioned Momo getting slaughtered by Tomura, him being unable to do anything, he clenched his fist as he grit his teeth.

"I'll get that Reality Crystal back... And I promise you that no matter what happens to me, I'll make everything right again!"

Alexis fully turned around towards him, "You aren't saying you're..."

Leonidus smiled at her, confirming her thoughts, she wiped tears from her eyes before hugging him.

"I would never have the courage to do something like that... Thank you... Thank you so much, me!"

"Please, don't thank me for doing that. I've been through enough losses. Let's get started, shall we?"

The two then meditated for hours on end, Alyx opened one eye, noticing that Alexis hadn't budge an inch.

"Sooooo... Is this all there is to it?" Alyx asked.

Alexis didn't answer him, he then noticed that she was asleep, Leonidus shook her awake which startled her.

"H-Huh!? Oh, right! The teleportation thingy! It's super simple! You just have to believe you can go home!" Alexis told him.

"I have to what? Y-You can't be serious, right?"

"Of course not! It takes a lot of effort to perform, what Gear can you go to?"

"Gear Six, or well, there's Infinite Mode and the God Quirk State as well. But I haven't mastered my Gears fully in order to tap into them without problem."

"What the fuck."

Alyx laughed as he shook his head, "See? You were right when you said I was super strong!"

"Ooookay... So I guess this won't be a problem for you then. You know how to open a portal to the Plane, right? It's basically like that, but searching even deeper within! I used my Yaoyorozu's Heat Energy to get back home, being I loved him bunches!"

"Okay, I see, so someone that I hold dear to me? Let me try it..."

Alyx stood up and opened a portal, at first it was a white void, he closed his eyes and felt for Momo's Heat Energy. As the portal began to materialize, he whistled something that him and his Yaoyorozu would know, waiting for a response. He opened his eyes, seeing a grotesque, bloody, warped version of Yaoyorozu and his classmates.

"Oh, hello." Alyx greeted.

"Hhhiiiiee...."

Leonidus slowly closed the portal, turning back around towards Alexis, clearly distraught.

"W-Was... What reality was that?" He questioned.

"That was just their appearance, they're super nice people! Outside of cannibalism and-"

Alyx put his hands out, "Ooooooookay, that's enough of that. Hopefully I don't stumble across them again."

Leonidus resumed his focus on the portal, time after time again, he would open up portals to other realities besides his own. One reality he found himself and Midoriya fused into one person! He put up one more portal, whistling the tune once again, to which he finally got a response.

"Alyx? What are you doing?" Momo wondered.

"Momo! There you are!"

Leonidus quickly stepped through the portal, keeping it open and thanking Alexis before the portal closed. Alyx squished Yaoyorozu's cheeks as he stared at her to see if anything was amiss.

"What was the last thing you did?"

"I talked to Laura and Ibduku's kid fwom anover world."

"Thank goodness it's you! You wouldn't believe what I've seen. Is everything alright here?"

Alyx took his hands off of her face, "Yes, so far everything is decently normal. We have gotten a little more otherworldly visitors, however, dear."

"A little more?"

Momo had him follow her downstairs, he saw that the dorms were filled with new people, most of which he recognized.

"We need to find that crystal, this is starting to get a bit out of hand. The only issue is that I don't even know where to look." Alyx remarked.

"Why don't you use that Infinite Mode ability of yours? Wouldn't you be able to scour the world for it easily?"

Leonidus sat down on a step, "That's the thing, both times I've used it, I've gotten help from someone. I've only mastered my first four Gears. I still have Gear Five and Six to go, but those are ridiculously tough to master."

"Hmmm... Then this'll be harder than we thought."

Alyx looked towards the crowd of people, "Unless..."

"Hey, uh, Alyx! You might wanna come to the door!" Izuku called out.

Leonidus got up with a curious look on his face as he made his way to the front door. He froze as he saw the dozens of people standing in front of him.

"My goodness!" Momo exclaimed.

"I have an idea." Alyx spoke up.

Without saying another word, Alyx walked outside passed the crowd of people, clones of him spread out across the sky. The clones shortly came back with a plethora of materials needed to construct a temporary shelter for the extra students. His clones got to work building the shelter, using Overdrive ladders and tools, him and his clones started their long, tedious work.

"Hand me that hammer, Alyx." One of them spoke.

"Right on it, Alyx!"

Jiro stood outside alongside Momo, Katsuki and Mikey. Shota eventually made his way outside, watching as clones of Leonidus walked past him with boards and trusses.

"What in the hell is going on here?" Aizawa questioned.

"Looks like he's building a home for our temporary friends here. I didn't think he'd have the capacity to even manage that." Mikey answered.

"Yeah, I never took him as a construction type of guy, honestly." Momo agreed.

Hatsume eventually seen the work taking place, offering her help and expertise with the project. For the next several hours, the air was filled with the driving of nails, the cutting boards, drills, and more. Alyx wiped sweat off his forehead as he finished putting up the last of the door frames on the third floor.

"Thirsty, partner?" Hatsume wondered.

She handed him a jug of water, which he gulped down within seconds, he handed her back the jug before looking down at his watch.

"Geez, it's getting pretty late already! At least most of this place is finished though. I've got at least a few more things to do before this place is ready to be lived in."

Hatsume leaned forward to pick something out of his hair, "Saw dust. Sorry, I just couldn't stand that being in your hair."

[Several Hours Later...]

As the construction went into the night and finally finished in the early hours of the morning, Leonidus finally rested for the day. Meanwhile, on an island facility somewhere in the western hemisphere, Onryo looked upon the Reality Crystal.

"I see that they're trying to prepare themselves... Interesting mortals they are, but how about I change things up a bit?"

Onryo harnessed the power of the Reality Crystal once more, instead of calling forth more storms, he instead decided to change the aspect of Alyx's own being. As Leonidus snoozed away, he awoke after hearing what sounded like lightning crashing down onto the Heights Alliance front yard. He looked around, noticing that things were slightly bigger than what they used to be, he hopped down off of his bed and made his way towards the door. Before he left, he looked at the alarm clock on his nightstand.

"I guess I was out for a while! They must've ate dinner by now." He noted.

Leonidus made his way downstairs into the Common Room, "Hey! Did you guys already eat or did you save some for me?"

"Who... Alyx?! Y-Y-You're a child?!" Izuku yelped.

"Huh? Whadda mean?"

Momo walked over and picked him up like a small child, it finally hit Leonidus as to why he sounded different, and why the things around him were much bigger than before.

"What the fuck!?" Alyx screamed.

"How did this even happen?" Sato wondered.

"I dunno! I just woke up to the sound of super loud thunder and now I'm like this! Whatever's going on, I bet the Reality Crystal is behind all of this, and I know just the person who might be able to help us find it!"

Yaoyorozu held him in her arms, "And who would that be, my tiny dear?"

"Amanda Vibraine! She knows a lot about spirits and stuff!"

"Wait, didn't you kill her Dad or something, bro?" Kaminari wondered.

"Yeeeeah... But she didn't exactly agree with the things her Dad was doing, so I think she'll be okay! If I'm gonna talk to her, I gotta leave right now, I don't wanna be a kid longer than I have to be."

"Well hang on there, junior! Why don't you take one of us with you?"

"I would Kami, but I'm kinda small now, so none of you can really come with me."

"I can fly now, remember?" Izuku mentioned.

Katsuki rolled his eyes and sighed, "I still don't understand why so many of you can fucking do that..."

"Well, if you're ready for an adventure, then let's go! I guess I could use the company." Alyx smiled.

The two boys got ready to go and set off towards the States. Izuku noticed how Alyx's hero suit actually fit around his now smaller body.

"Hey, so that hero suit of yours, how does it still fit you?" He wondered.

"Oh, simple! It's not made by natural means, the scientists at I-Island developed a sort of 'symbiotic' technology that allows hero costumes, among other things, to be developed to suit the user's body."

"I see, I guess Melissa's the one behind all of that?"

"Yep!"

Midoriya kept looking at Alyx as they continued their journey to America, questioning even more how he was able to use Gear Six with his body. Alyx looked back at him after reading his thoughts.

"I am literally like an atom bomb."

"Wait, what?"

"I'm just kidding! My body is well used to my Quirk by now! It just takes a bit to get the juices flowing."

[Two Hours Later...]

Izuku and Alyx landed down in front of a small home in Boulder City, Nevada. He knocked on a door and waited for someone to answer it.

"Are you sure this is the place?" Midoriya asked.

"Yeah, I used to hang out here with her and my friend Joshua all the time."

The door slowly opened on it's own, the boys walked in to the barely lit home, in the room adjacent to them was Amanda. She was in the middle of some sort of seance, candles were lit around her.

"State your business. I don't recall any clients today." She spoke.

"I didn't think I had to call, Amanda!"

The lights turned on and the candles extinguished as she opened her eyes. Amanda looked back to see a small Leonidus standing in front of her.

"Alyx? What did you get yourself into?"

"Would you be upset if it was Reality Warping stuff?"

Amanda sighed and facepalmed, "Of course, why would it be something simple? I'm assuming it has to do with the Reality Crystal of yours?"

"How'd you know that?" Izuku questioned.

"I tell her everything! She's like my backup guru!"

"If you weren't a child I'd deck you in the face right now. I've been trying to track the source down as well. I guess I could say all four of us have been."

"All four? Who's the other one?"

A door slid open as Amanda looked over at it, another Amanda stepped out of the room, she waved at the two.

"Huh, an alien Amanda? Cool!" Alyx beamed.

"Indeed! It's a pleasure to meet you. If you're wondering, we've almost pinpointed the approximate area of the Reality Crystal. We were going to pursue it ourselves, but being you're also looking for it, we can share details with you once we get them."

Leonidus stuck his hand out, "Awesome! We'll be in touch then!"

Alien Amanda patted his head instead of shaking his hand. With a new friend made, Leonidus was simultaneously building an army to combat Onryo and the Reality Crystal. But little did he know, Onyro wasn't working alone, he too had made allies with a familiar foe!
