"Do you know I have the book of all the Demons? I know every type of demon!

Blaze: fellow pyro! Wassup?

???: Huh?

Soojin: *looks up to him and sighs* Hey fire bastard!!!

*turns around* Huh, how did you call me?
*Suddenly fire starts bursting out of the ground under Soojin

*all the fire quickly turns into ice and everything around her*

*he charges towards her with a fire punch so powerful that it could destroy a mountain*

*by the impact of the it dragged her 1 feet away but she looked unharmed*
Soojin: "your good..."

"Lets see if you can handle this"
*he blasts a solar wind made form Hell Fire

Regitur: *saddened and confused* is that you sprinkle?

"what did you just call me?
*He charges towards him, and following him theres a line of fire*

(sprinkle is his ex)

(oh ok)
*Pillars of fire burst out of the ground*
*He stops infront of him*

Daelo: "Hm?"

???: What are you doing here

Daelo: "Existing."

???: *walks through the street, calm, uninterested and undeterred, *

*he hits him, he gets flinged 20 meters in the air*
???: You, you, you killed everyone on my planet!
*He jumos in the air, leaving a crater on the ground*
*He uses Continental Force and the guy with purple flames gets flinged about 100 meters away*

(Wait, who did he hit?)

(your OC)

???: *stops in mid-air, is almost unharmed except for a cut on his cheek that quickly goes away* I think I'd remember causing the extinction of a planet.

???: You sure do!
*Uses Pangea, now you have 5 seconds to run or attack*

???: *thinks* No, I'm pretty sure I don't. It would be quite an achievement, but no, I spent the last few thousand years in a death coma, so no.

*the five seconds pass, he is very injured but not enough to not use the ability*
*A flash of light, is this the end? Are you dead? Or is this all a dream? No, these are the last moment before the disaster*
*Anyone that was in a 70 meter radius was killed, burnt by the light*
*The person looks down at his body, almost fully burnt*
*He falls to the ground, in pain*
*He stays there, is he dead? Is he resting? Or is he crying?*

(Your descriptions are cool man. Thank goodness we're all OP as heck)

??? (purple flame guy): *most him is gone, except his head. But it starts regenerating slowly, but surely* I will not lose to you. I have only lost to gods, and I won't lose to them again.

-meanwhile jhon is dead-
???: Horace, *cough* Horace
*Another person falls from the crack in the sky*
????: You may be strong but im stronger
*Horace starts floating 3 feet in the air*
*He raises his arms and time freezes*
*He runs to the purple flams guy and starts punching him then time starts again and the purple flams guy flys into the air, 1 km away*
Horace: Conan are you ok?
Conan: Yes yes
?????: Hello!
Conan: Anand?!
*Anand has a purple aura around him*
Anand: Good news i killed 15 people
Horace: That explains the purple aura

Purple flame guy: *laughs maniacally* They want to dance? LET'S-
*his eyes become black and normal*
???: Look man, there's really no point in fighting these guys. We never die until we win, and I think that's a pretty long time. I need to finish my homework.

Zach: Hehehe, I have my own tricks too *suddenly the purple fire starts to have a blue tint*
Zach: Hell fire isn't always hot
*The purple flames become Icy Hell Fire*
Zach: The soul of hell isn't hot, its cold as the heart of the Devil
*Suddenly a crack opens in the ground and you can hear a very deep voice*
???: Hello little boy, do you need my help?

*he materializes behind Zach, having been forced out of the flames, a smirk on his face. But then the purple shimmer in his eyes turns to a more normal black as he hears the question.
???: *teenage boy voice* Uh, probably not yet. I would appreciate not being killed though. Being put together cell by cell is not as fun of an experience as you'd think. *nervous chuckle* Uhm, wassup Zach, you seem fun. But we were just passing through, don't mind us, Gyatsu is feeling particularly devil-ly today. We'll get out of your hair.

Zach: What?
???: Naturally I wasn't talking to you
*A red firery hand pops out of the crack*

???: O-oh yeah, I think that makes se- *eyes become purple again*
???: And who's offering this BOY help then?

Zach: The Devil!
*Zach grabs his forehead and slams him on the floor*

???: *dissolves into purple flames again* THE devil? It's always THE devil. It's A devil, boy. You just live enough to forget that there are others. *materializes 10 feet in the air, purple still flames coming out of his eyes and curling into devil horns on his head* Maybe I'll be the reminder.

Jhon: *goes inbetween them* Now stop you two, if you both continue, both will die
*A crack opens in the sky above Jhon*
Zach: Em Jhon what are you doing
Jhon: Im not doing anything
*The crack becomes larger*
Zach: Jhon?
*The crack becomes even larger*
*A person falls from the crack directly on top of Jhon, making him fly into the air*
???: Where am I? Who are you?

???: *frowns* You're interrupting. Why?

???: You, you seem familiar
*He rushed towards the guy with a Continental Punch*

???: Hm?

*he charges towards him again with another fire punch*

???: *lays there, the gurgling now sounding more like ragged breathing*

*he hits him*

???: *dissolves into purple flames*

*looks confused* *a icy portal appears* *a black figure comes out of the portal*
???: Zach! Stop this nonsense!

*the fires on the street flicker, their outlines turning purple. A voice is heard throughout the flames, the same ragged breathing, but getting better, slowly turning into manic laughter*
???: *echoey, dark and malicious voice* I think you should listen Zach.

*zach turns around a blasts a solar wind*

*nothing. The tint of purple on the flames becomes darker, and starts taking over the flames*
???: All this rage. I bet it's not healthy for a young...hmm...demon, such as yourself.

Zach: I am used to it, I come from hell
*Suddenly a colon of hell fire bursts out of the ground beneath the guy with purple*

*??? is still nowhere to be seen, but the column of hell fire that erupted from the ground suddenly becomes purple and stops moving. Completely. Even the flames on it stop swaying. In fact, all of the flames stop swaying*

???: Ahh. Hell. I was like you once, little demon. Rageful. Prideful. Arrogant. Until I felt death.

*All the purple tendrils of flame sway together, matching ???'s flow and rhythm as he continues*

???: As I reincarnated in this...pathetic, human form- *a teenage, annoyed voice is heard saying "HEY!"* -my rage took on a more cold form. I became more efficient. Who wants to be a demon anyway? All that uncontrolled....RAGE.
*the flames shoot into the sky, now as tall and still as skyscrapers*

Conan: Hey you!

*A black goo like substance appears on the ground infront of ???*

*It stretches and flattens*

*Then it grows into a more human form*

Jhon: God, that hurt

*he looks at him, saying with his eyes, get out of here*

???: *completely ignores him, acting like he owns the universe*

*keeps looking at him*

???: *is already a block away from him*

*he charges a fire blast that could tun into steam an entire iceberg* *he shoots it*

???: *stops and raises his head thoughtfully, then shrugs and sidesteps the blast*

*he charges*

???: *turns around and looks at him, and smiles*

*he strikes him with a fire punch, so powerful that i could destroy a mountain*

*his chest crumples in and he flies back, several meters. After a few seconds, you can hear rhythmic gurgling sounds from him*
