Third Person POV 

Odogaron: So why are we up here? 
She asked as she looked at Nargacuga, sitting down on top of a roof. 

Nargacuga: Did you not hear him? 
She asked as she glared at her. 

Odogaron: Yeah. I heard him. 

Nargacuga: Then why are you asking. 
She said as she looked away, scanning the streets of the city. 

Odogaron: Why are you so uptight about him? 
She asked as she continued to look at her. 

Nargacuga: What do you think. 
She growled as she continued to look at the city streets. 

Odogaron: Hmm.. Fine. Be like that. 
She scoffs before laying on her back, laying her head on her hands. 

Nargacuga: Let him kill the boy and we can finally get away from him. 
She thought to herself before turning the side, her eyes glaring down another street. 

Nargacuga: Odogaron. Let's go. He's nearby. Tell him we've found his scent. 

Somewhere Else 

All Might: Ryuko, I'm glad you were able to come in. 
He said as he looked at her. 

Ryuko: I-Is this about my son? 
She asked nervously. 

All Might: Yes. 
He said as Ryuko looked down. 

All Might: We're not here to condemn or anything. 
He said as she looked at him. 

Ryuko: We? 

All Might: We've...found out what happened to him at USJ. 

Ryuko: I thought you told me that...the Nomu was the one who put him in there. 
She said as she continued to look at him. 

All Might: We're here to talk about the other him. 
He said before pressing a button as the room slowly went dark, a projector lighting up the room as it showed Y/N standing in front of Deku and a group of students. Ice spiking out of the ground as Shigraki looked at him. 

Ryuko: I-Is this what happened at USJ? 
She asked as she looked at him. 

All Might: This was what we got from the cameras around USJ. And here's another. 
He said before showing another photo. Showing Y/N gripping Alex by the throat as his slit eyes glared into Alex. Alex grasping onto his hand as he attempted to pry them off. 

Ryuko: N-No. 
She said before looking away as All Might looked at her. 

All Might: Ryuko, what can you tell me of him? 
He asked as Ryuko continued to look away. 

All Might: Can you tell me of Alatreon? What is he? 

To Y/N 

Momo: What happened to you at USJ? 
She asked as she looked at him, the two students walking down the street. 

Y/N: I was put into the hospital Momo. 
He said as he looked at her. 

Alatreon: And killed a few guys. 

Momo: The doctor said you should be in the hospital for a week but you're up and walking around. 

Y/N: How long was I in the hospital? 
He asked as he looked at her. 

Momo: You were only in the hospital for 2 days. 

Y/N: Oh... 

Momo: Yeah. 
She said before walking up to a diner. 

Momo: Want to have lunch here? 
She asked as she looked at him with a small smile. 

Y/N: Yeah. 
He said before following her inside while Odogaron and Nargacuga watched from afar. 

Odogaron: Look at those two lovebirds. 
She said with a small giggle as Nargacuga pulled out a phone. 

Nargacuga: Found him. 
She muttered into the phone, hearing a dark chuckle on the other end. 

???: Good. Keep an eye on him until I get there. 

To Y/N 

Y/N: Didn't think you would want to come to this one. 
He said as he looked at Momo. 

Momo: Why do you think that? 
She asked as she laid her head on her hand. 

Y/N: Thought you'd want something...cleaner. 
He answered as Momo giggled softly. 

Momo: We're just grabbing lunch Y/N. Doesn't need to be expensive. 
She said as she continued to look at him with a smile. 

Alatreon: Way to go you idiot. 

Momo: Remember when we found out about our quirks? 
She asked as Y/N slowly nodded. 

Y/N: Yeah... 

Flashback 

Young Momo: Hey Y/N! I just found out what my quirk can do! 
yelled with a smile as Y/N turned to her. 

Young Y/N: Really? 
He asked as she nodded excitingly. 

Young Y/N: What can you do? 
He asked as Momo quickly turned around, a small glow forming around her. 

Young Y/N: Momo? 
He asked as she turned around, holding a small toy in front of him. 

Young Momo: Tada! 
She yelled excitingly as Y/N chuckles. 

Young Y/N: How did you do that? 
He asked as he looked at the small toy. 

Young Momo: I used my quirk to make it. Do you like it? 
She asked as she hugged it tightly. 

A/N: Imagine it as Momo. 

Young Y/N: Yeah. 
He said as she smiled brightly. 

Young Momo: So, what can you do? 
She asked as she continued to hug her toy. 

Young Y/N: Well... 

Young Momo: What is this? 
She asked as she looked at him with confusion. 

Young Y/N: I can only do this. 
He said as he held his hand out, forming a ball of ice, looking away from her. 

Young Momo: That's so cool! 
She yelled at him as Y/N looked at her with confusion. 

Young Momo: You can use ice! That's better than mine! Is there anything you can do? 
She asked as she looked at him excitingly. 

Young Y/N: T-That's all I can do. 

Flashback Ends 

Momo: Remember? 
She asked as she continued to look at him. 

Y/N: Yeah. I remember. 
He said as a waiter approached them with a tray in her arms. 

Alatreon: Someone's here. 

Y/N: What? 
He asked as the waiter placed the food on the table. 

Alatreon: Get out. 

Y/N: What are you talking about. 

Alatreon: Something's coming. 

Y/N: What's coming? 

Waiter: Enjoy you two.
He said before walking away as Y/N stared blankly at the food. 

Momo: Y/N? 
She asked as Y/N remained silent. 

Momo: Y/N. 
She called out his name as Y/N looked at her. 

Momo: Are you okay? 

Y/N: Yeah. Yeah. I'm okay. 
He said before grabbing his plate. 

Alatreon: Get out. 
He growled loudly. 

Y/N: Why. 

???: Oh my god. 
A voice gasped as Momo turned around to see a purple mist slowly flooding the room. 

Momo: W-What is that? 
She asked with fear as people suddenly collapsed onto the floors. 

Momo: W-What is happening!? 
She yelled as the two stood up, Y/N looked at the windows as Momo tugged onto his arm. 

Y/N: Window. 
He said before groaning loudly, seeing a purple aura slowly forming around his arm. 

Momo: Y/N! Watch out! 
She yelled as a man covered in purple aura ran at them. 

Y/N quickly pushed Momo out of the way before being rammed into the wall. 

Momo: Y/N! 
She yelled as Y/N grabbed the man by the throat before throwing him towards the window, shattering it. 

Y/N: Get. Out. 
He growls as Momo quickly climbed out before following her through. A purple hue slowly surrounding Y/N before stepping out onto the street. 

Momo: Y/N, are you okay? 
She asked as she looked at him, her hands on his shoulders. 

Y/N: Yeah. I'm fine. I'm completely fine. 
He said as a purple hue continued to surround him. 

Momo: You look like you need to get check-WATCHOUT! 
She yelled before seeing Y/N fly into the diner's wall, a man in purple standing in front of her. 

???: Didn't think a human of all things would made Fatalis crumble with fear. 
The man spat as Momo watched him with widen eyes. Seeing his eyes glare at Y/N as purple scales ran along his body. 

???: Look at you. 
The man said as he looked at her, her eyes widening as she stumbled back. 

Y/N: W-Who the hell are you. 
He groans before coughing up blood. 

???: Still alive huh. Don't worry, you'll survive. 
He said as he slowly raised his hand towards Momo. 

Y/N: R-Run Momo. 
He coughs as he looked at the stranger. 

???: With you, you shall spread this virus amongst those here. 
He said as purple mist flooded the surround area, coating it in purple as Momo starts to cough. 

???: Good. 
The man grins wildly as Momo fell to her knees, coughing loudly .

???: Feel it's effects. 
He said before approaching Y/N, looking at the weaken boy. 

???: Now to claim my reward. 
He said before reaching for Y/N. 

THUD 

???: What the? 
The man gasped with confusion as Momo continued to cough loudly, seeing Y/N gripping his hand as a purple hue surrounded him. 

???: H-How is he
He groans louder as Y/N threw him into the diner, sending him through the wall and into the floor. 

???: W-W-W-What was that? 
He gasped with confusion before standing up to see Y/N charging at him. His slit eyes glaring at him as the purple hue covered him. 

???: W-What the? T-This is no regular boy! 
He yelled to himself as Y/N reeled his arm towards him. 

THUD 

???: Gah! 
He yelled before crashing into another wall as Y/N continued charging at him. 

???: T-T-This is no regular boy! 
He groans loudly before being kicked out of the diner, sending him into the ground near an unconscious Momo. 

???: W-W-What the hell. H-He should be unconscious. 
He groans in confusion as Y/N walked out of the diner, showing his slit eyes as lightning flickered around his body. Fire and ice slowly running around his arms. 

???: W-Wait...L-L-Lord Alatreon?
