Putting Out the Sapphire Fire of Instantly

Izuku and Katsuki are glaring at the sudden arrival of the new guy who shockingly also has powers of his own, creating blue fires from his hands and right now using that power to burn some trees in the jungle.

"Don't think I'm gonna hold back just because you two are a couple of kids who are in way over their heads." Dabi mocked.

"Oh yeah, then let see how you like it when I'm over your head!" Katsuki blasted himself at the enemy.

"Kacchan, wait!" Izuku tried to call back his friend but is left ignored.

Katsuki soars up and dives down when he's right above the blue firecracker bastard for a fast axe-kick for the head, but Dabi wasn't having any of that as he bends down and crosses his arms with his hands facing Katsuki and unleash a big burst of his blue fire attack.

"Shit!" Katsuki instantly moved his body out of the way with only one of his gauntlets getting a slight burn from that fire attack.

But Katsuki wasn't done as he zooms around and goes for another attack with one hand thrown at his ugly face only for Dabi to react in time to block that exploding attack with his own fiery defense causing an explosion between the two.

Katsuki flies around the smoke cloud trying to attack the guy again, but a big stream of blue fire came out forcing him to dodge.

"Didn't you mommy teach you not to go near fire?" Dabi asked sarcastically with a laugh.

"That old hag never shuts up about that!" Katsuki yelled back.

"That maybe the case…" Izuku charged at Dabi.

Dabi saw him coming and conjure a literal fire wall to block his path though Izuku isn't scared, maybe a bit, but not enough to stop him as he claps his hands together to blow open a path for him and he leaps for a flying kick at the villain though Dabi dodges that one.

"(He's fast to be able to dodge my speed.)" Izuku thought noticed this.

Izuku landed on one burning tree and leaps back at the guy to punch him down to the ground though Dabi dodges that too and blasted a big fire at the kid to burn him alive, but Izuku was able to dodge that at the last second though the glove of left hand got burned.

"Shit, shit, shit, shit, shit, shit! SHIT!" Izuku quickly took off the glove, toss it to the ground, and repeatedly stomp it to put out the fire.

"Aw, I'm sorry, was that important to you? Send me the bill." Dabi mocked and swing his arm to unleash another fire attack.

Izuku quickly runs to dodge it and then goes in to attack the fiery bastard while he's distracted fighting the damn nerd, but Dabi hasn't forgotten that he is fighting two and blast another fire attack at the exploding boy making him dodge.

"(Fuck! He's not leaving himself any openings!)" Katsuki thought cursed.

"I have to say, you two are doing a lot better than the other fuckers who were unfortunate enough to cross me and got burned in seconds." Dabi commented.

"You might even be more fun to cook!" Dabi said with a smile starting to look insane.

"The only thing that is going to be cooking is your ass!" Katsuki shouted landed to Dabi's right to throw his right hand to attack.

Dabi narrowly dodges the blast, only getting grazes on his cheek which only seems to excite him some more, then he counterattacks with his flaming hands trying to burn him, but Katsuki dodges each strike and tries blowing him to bites though the enemy also dodges.

"(This is unlike anything we have seen before. This guy is not a regular human besides the fact he can use fire power, it could even put down that Nomu monster we fought by himself.)" Izuku thought felt this guy is more dangerous.

"(But even so, he comes to this island and threaten to destroy it just to get someone.)" Izuku thought wondered before he charges into the fray.

Dabi managed to grab Katsuki's arm forcing the exploding down the bend down and smirks as he uses his free hand to throw down a flaming punch.

"Texas Spin Mash!" Izuku zoomed in to intercept Dabi with a punch while spinning his whole body through and the spin would also land another punch on the chest.

"Now I got you!" Katsuki palm strike Dabi on the chest that had the powerful explosion sending him flying back.

"Nice job, Kacchan." Izuku said with a thumbs up.

"Shut up! I totally had him until you butted in and ruin my moment to land a hit on him!" Katsuki shouted in rage, not wanting to thank the guy even though he is a little grateful.

"Come on, we can't let him out of our sight!" Izuku charged in the direction Dabi was sent flying.

"Don't tell me what to do!" Katsuki yelled as he goes with Izuku to find that blue fire bastard.

Dabi just recovered from that explosive attack and only have a small burn on his shirt.

"This is starting to get really fun." Dabi chuckled.

(With Mirko and Melissa)

Mirko taps her bunny foot fast upon waiting for her beloved Deku and that exploding boy to come back from the race training, but for some reason, they're taking much longer to get back than it should.

"Shit, what the hell is taking those two so long?" Mirko asked.

"Hey, Melissa!" Mirko asked, scaring the girl a little.

"Huh, yes?" Melissa asked, trying to calm herself down from that sudden yell.

"Are you sure the boys made it to the statue of Goddess Nana?" Mirko asked.

"Yes, according to the camera feed at the statue. Izuku was the first one to made it with Katsuki being right behind him." Melissa answered, showing the Amazon Queen a picture of the boys finishing the race training from her tablet.

"Then why aren't they back yet? This is so unlike them." Mirko started to feel worried.

"Maybe we can play what they're doing right now." Melissa typed onto her tablet to what happened next.

"It looks like they're about to head back, but wait… What are they doing?" Melissa was confused on what the boys were doing at the time.

Mirko watch this feed as well, saw the boys looking at something then Izuku jumps high into the air for a moment then came back down with a worried look on his face.

"I don't like this." Mirko said.

"What do you think happen to the boys?" Toru asked.

"I'm sure it's nothing serious, they probably gone too far past the statue and got lost." Kyoka said, telling herself that.

"I don't know. I'm getting a bad feeling about this." La Brava hoped this feeling is wrong.

"Your majesty! This is terrible!" Midnight shouted, running toward the queen and Melissa.

"What is it, Midnight?" Mirko asked.

"It's Izuku and Katsuki! We just got word that there is a fire in the jungle and believe it was cause by an intruder!" Midnight alerted, shocking the queen.

"An intruder on the island? Just fucking great, that's just what we need right now!" Mirko growled.

"(But it's weird, if there were any intruders on the island then the security surveillance system should've picked this up by now and alerted us.)" Mirko thought wondered why the alarm isn't going off.

"Well, at least we know what the boys are doing." Mirko sighed.

"But that's not all, apparently the fire that is destroying the area where they are is very different than the normal ones." Midnight informed.

"Huh, what do you mean by that?" Mirko asked.

"According to what Izuku said in the message, the fire is blue." Midnight answered.

"Blue… fire…" Melissa started to feel something off upon hearing that.

"Blue fire? Are you fucking me with jokes right now, Midnight? Why would Izuku ever say that the jungle is being attacked by blue flame?" Mirko asked in confusion.

"I wish it was a joke, but this came straight from Izuku, and this might be connected to the intruder." Midnight said.

"Blue fire…" Melissa started to feel a slight headache as a memory she has forgotten started to come back.

(Flashback)

The scene shows of a boat with a storm looming over them, and a burst of blue fire explosion erupting from the boat.

Melissa is running on the side of the deck trying to get away from the man causing the blue fire destruction, she even tried throwing some stuff she could get her hands on at the man only for them to get burned and turn into ashes.

"I thought you'd be smarter to know that none of those things can stop me." Dabi mocked as he steps out of the blue fire.

Melissa is really, really panicking right now from all the danger that is happening when she was working on her invention and suddenly this man showed up for the purpose of kidnapping her for some unknown reason.

"If you're gonna keep on running then go on ahead. I do love the chase." Dabi smirked.

The inventing woman knows that this guy is WAY too dangerous to face head on and already so many people got killed because of this guy.

Which is why Melissa had to lead him away from all the people and hopefully think of a plan to stop this guy before he does any more damage to the ship.

"Your fire maybe hot, but you haven't even burned me!" Melissa taunted and immediately turned around to run again.

"Yet." Dabi said before walking for the chase.

Melissa quickly made her way to the deck of the ship trying to look for something that could help her, then her eyes widen spotting a blender with crushed ice.

"Yes, that could work!" Melissa ran toward the blender and ice because she has an idea.

Melissa reached into her pocket to pull out a metal ball, the invention that she has been working on during this entire boat trip, believing this could be the key to helping her deal with that blue pyro man.

"Just one elemental ball should do the trick." Melissa dropped the metal ball into the blender then pour as much ice as she could into the blender.

Then a blue flame attack went past her on purpose by Dabi just to scare her, it worked a little though she's more focused on what she's doing as the inside of the blender and under all that ice is glowing white and blue.

"Yes! It's working!" Melissa smiled.

"Making yourself one last smoothie before being taken away? Bet you really don't like my fire." Dabi said.

"My boss gave me a very specific order to not kill you, saying that your big brain is more important alive." Dabi mentioned.

"So, I'll just burn your legs, so you won't be able to get away where you're going." Dabi aimed his hand at Melissa's legs.

"Sorry, but I'm afraid this is the part where I give you the cold shoulder." Melissa said with a confidence smile but still scared on the inside as she hopes this works.

"Please, there isn't anything cold that I can't melt away." Dabi said.

"Then try melting this!" Melissa rolled the blender with the ice and metal ball toward Dabi.

"Really? A fucking blender!" Dabi laughed.

"Alright, now you're done for!" Dabi unleashed his blue flame at her legs while also consuming the stupid blender.

But what he doesn't know is that he just fell right into Melissa's trap as the elemental ball glows brighter and suddenly exploded into a big ice wind that is colder below zero, and that wind blew Melissa right off the boat.

"You bitch!" Dabi screamed and tried to go after her, but for some strange reason he couldn't move forward.

He looks down to see that his feet are suddenly frozen in ice and the ice is spreading up to the leg that will keep spreading throughout his entire body.

"Damn it!" Dabi quickly unleashed his fire all over his body to fight the ice.

Meanwhile, Melissa fell into the water and her mind went blank from the ordeal as she drifts away from the boat by the ocean current and the storm.

(Flashback End)

"I remember now! I know who he is!" Melissa realized fully now.

"Uh, what was that?" Mirko asked, hearing that the outside girl just said something.

"Queen Mirko, I need you to take me to my room right now!" Melissa requested.

"Whoa, whoa, what's this about now? You're making it sound like you suddenly know who this intruder is." Mirko was surprised by the sudden approach from Melissa.

"Because I do! I promise I'll explain on the way, just get me to my room!" Melissa said.

(Izuku and Katsuki vs Dabi)

Katsuki screams with another explosion at Dabi who throws down his fist to clash against him causing another clash of explosions, and then Izuku blitzes through to attack Dabi with a punch though he was able to dodge it with only a tiny cut from the fast punch.

But Izuku wasn't done as he turns his body to throw a backward swing kick to push him back which Katsuki didn't waste any time to attack again.

"AP Machine-Gun!" Katsuki fired large rapid-fire explosions at Dabi.

Dabi quickly brought up a tall fire wall to protect himself from that firing attack.

"This is fun!" Dabi chuckled and push his hands forward to make the fire wall move towards the young heroes.

"Delaware Shatter Smash!" Izuku unleashed a powerful small wind attack from his fingers after channeling 25% of his Quirk for that instant moment and did it a few times too.

Those wind blasts were able to pierce through the fire wall causing it to be blown away and hit Dabi square on knocking him down.

"Got you!" Katsuki zoomed down at Dabi from above and slams his foot right in the stomach making him gasp in pain.

Dabi was having fun with this, but now he is getting really annoying and tries to grab Katsuki's leg to burn it off only for Katsuki to jump away.

"You fuckers are really making me waste time when I should be out searching for that girl." Dabi glared at the two.

"(He mentioned he came to this island looking for someone, that would mean this girl would have to be from the outside world from how he describes this girl to have escape from him. And I think I know who that is.)" Izuku thought figured out it's Melissa Shield.

"Whatever you want with Melissa Shield, you will never get past us!" Izuku was determined to protect Melissa from this madman.

Dabi started laughing crazy having hear that this kid just figured him out, but it didn't matter to him since he and that exploding brat friend of his are going to die soon enough.

"Nice job on solving the case! Now let see how you'll solve the case of being burn alive!" Dabi unleashed two streams of fire at each boy.

(Music: Inferno, Promare OST)

"If you're looking for me then here I am!" Melissa called out.

The boys and Dabi turn to see Melissa, riding on Mirko's back, is coming at them full speed.

"Melissa, what are you doing? You need to get out of here!" Izuku worried.

"(Looks like it wasn't trouble finding that bitch.)" Dabi thought smirked, believing that he is going to complete his mission.

"Don't worry, I have just the thing to help deal with this guy." Melissa held out a metal ball.

"(Why am I suddenly getting a cold feeling from this?)" Dabi thought felt a memory of the ice from the boat coming back to him.

"Mirko!" Melissa tossed the metal ball in front.

"You got it!" Mirko nodded and flip over to kick the ball straight for Dabi.

"No you doubt!" Dabi unleased his fire at the ball, but it explodes freezing the very fire into ice and reaching all the way to his arm and shoulder.

"What the fuck! This feels colder than before!" Dabi gasped.

"Now you're mine!" Katsuki launched himself into the air and start spinning faster and faster with his explosions going down at Dabi.

"Howitzer Impact!" Katsuki landed the powerful explosive attack on Dabi right in the face and sending him crashing through some trees and further away.

"Guess that's the second time I've given him the cold shoulder." Melissa smiled.


KO a new chapter is done and hope you all enjoy it!

Dabi was a tougher opponent to deal with even with the combined might of Izuku and Katsuki as they were having a hard time getting past his fire, but Melissa saved the day using her genius inventing to put a freeze on Dabi as a little payback for trying to harm her before.
