I'm totally using the shit out this dynamic. If you know this song, it's from Dangerkids, also known from sonic forces I believe.

Leo's POV.

"THIS IS ALL YOUR FAULT!"

"I didn't mean to—."

Smack, straight in the face.

"Yeah, you are clearly no good."

"Yo, don't say that," Kenny says.

The group throws him away, continuing the violence.

"What is it? Can't fight, daddy's little boy."

I bite his fist before it collides.

"No, I can fight. I do it to survive. Want a piece?"

He hits me again, I push him off.

"LEOPOLD, INTO THE OFFICE!"

"He start—."

"Don't try it."

"No, I will try it. It's unfair."

The guy kicks me towards the teacher, getting nothing out of it.

~Time skip.~

"Chaos, give him back," Mysterion says.

"No! He's done too terrible things for me to let him go!"

"Is this really the way?"

"You wouldn't understand, would you?"

"No.... I don't."

"I'm the tallest of mountains, I am the roughest of waves. I'm the toughest of terrors. I am the darkest of days. If that's what it takes to get away from this, I mean. If that's what it means to get away from a daily abuse."

"Chaos, this is not—."

"I'm the last one that's standing, don't try to stand in my way."

I push him further, causing him to hit the wall.

"Cause I've been up against better,
just take a look at my face."

I used to have one scar, now that's seventy. You don't survive a pacifist!

"Cause if you're messing with me, I am a dangerous weapon, I am the sharpest of blades... I'll cut you down in a second."

"Butterfly..."

"SHUT! WHY SHOULD I LISTEN TO YOU? THERE IS NO OTHER WAY."

"You should listen Cause I was born in this pain, it only hurts if you let it."

"Haha, that's hilarious. I was born into this pain as well. So if you think you can take me with you to your 'good side' Then you should go and forget it."

I laugh a little, hearing the people that would kick me on the daily mock me.

"And after all this time you're back for more."

They look terrified.

"I won't stop until they know my name and what you did to IT!"

I try to calm down, looking through my minions.

"So I'll take what's mine and start this war."

"Butterfly, please, this isn't you."

"I'm coming at you like a tidal wave. I have an army, I've defeated all you've had."

"Yeah but please reconsider, this is not the way to go!"

"So look around you and tell me what you really see I'm never ending that's the difference in you and me."

"I think the never ending one is me.
Cause when your time is up and everything is falling down, I'm still here!"

I laugh and look at the bodies my army has punched out.

"It's only me and you, who is gonna save you now?"

I attack him, he falls back, I never have.

"You can't hurt something forever, Kenny. It breaks and when it breaks, it takes the ones that hurt it with it! So take a look around you and tell me what you really see."

"We can fix it, they'll be sorry."

"You live a lie and that's the difference in you and me."

I hit him so badly he falls back, this time not due to shock.

"I have the power, lemme show you what it's all about."

I continue to hit him, hearing his cries of pain. Something about is moving but not enough.

"It's only me and you, who is gonna save you now?"

His eyes open.

"Who is gonna save you now?"

He finally starts attacking back.

"I am the tallest of mountains and
don't you ever forget it."

He's properly hitting.

"If you step in the ring then you're gonna regret it."

I laugh and shield.

"Yeah, 'cause if you're messing with me then you should know that it's over," I say.

I continue to shield before kicking him in the lower stomach

"I don't crumble for nothing!" I yell.

"I got the world on my shoulders," he mutters, as if to find a reason to continue to fight.

"And after all this time you're back for more," I say as he gets up again.

I won't stop until they know my name and what I'm here to protect! I won't stop until you know that i'm here to protect you, amongst others. It doesn't need to go to this, Butterfly, I love you. I know you're not like this!"

"So I'll take what's mine and start this war," I say, trying to keep myself in the fight

"I'm coming at you like a tidal wave," I say, finally mind back in the fight.

I catch him by the neck.

"When everything you know has come and gone, I'll be here. I know it's hard, Butterfly, please... we can fix this," he says.

"You are at your lowest, I am rising higher," I say.

I throw him yet again, this time he screams.

"Only scars remain of who I was," I say.

"What I find in the ashes, you lose in the fire," he says.

"When there's no one left to carry on," I say, trying to hold the tears.

"Butterfly, please, this is an illusion, this hatred, open up your eyes and—."

"This pain persists, I can't resist," I say.

I push him into the wall yet again, looking him in the eye.

"But that's what it takes to be infinite."

He shakes his head.

"Yeah," I say.

He laughs and points towards the people taken down.

"So look around you and tell me what you really see. You are no better than the people you're against! You know what? I'm never ending that's the difference in you and me. Cause when your time is up and everything is falling down I'm still here. That's what's being infinite! It's not good. It's only me and you, who is gonna save you now? Who's gonna save you from YOURSELF?"

He pushes me off.

"So look around you and tell me what you really see."

I feel the tears roll down.

"You live a lie and that's the difference in you and me, not everything is pain! You can't take it all out on the people that didn't cause it! You don't even need to take it out on people like your friends! I have the power, lemme show you what it's all about, it's about being able to take self defence and selfishness with their differences. So yeah, It's only me and you but the truth is who is gonna save you now? Can anyone save you from yourself? Can I save you? Can you save yourself?"

I hug him, crying. He kisses me, careful.

"Truth is............ you need help. Who's gonna save you now? Who can do it?"

I sigh.

"I don't know."
