Deku's Exploding-Smash Victory!

In the room on the fifth floor, Tenya is standing next to the weapon guarding it though not sure if there's even a plan to guard it in case someone comes here to take it and heard an explosion sound from downstairs.

"Bakugo, come in! Give me a statue report. Where are you?" Tenya asked through the communication earpiece.

"Just shut up and defend the weapon. I got more important things to worry about." Katsuki responded harshly.

"Are you forgetting what our mission is?" Tenya reminded his partner, then heard a click gasp Katsuki had just hung up on him.

"This isn't the time for radio silence! We're suppose to be partners!" Tenya said angry.

(Monitoring Room)

"Hey, who's Bakugo talking to? I'm not hearing anything; can we get a sound on this video?" Eijiro asked.

"He's got a radio in his ear so he can talk to his partner. I gave to him before the match started along with the map of the building." All Might answered and picked up a rolled-up capture tap.

"Wrapping this around your opponent means you've been apprehended them, and they're out for the rest of the game." All Might explained.

"So, there's a fifteen-minute time limit, and the good guys have no idea what floor the nuclear weapon is hidden on, right?" Mina asked.

"It may sound like the hero team is at a disadvantage, but Pro heroes like father and others have to find a way to outwit the villains on a daily basis." Medaka explained.

"Oh, guess I haven't thought about that much." Mogana surprised to hear that.

"That's right, even when things aren't in our favor, we still fight." All Might nodded as the students understand this.

"All together now… Let's hear a PLUS ULTRA!" All Might said the family motto together.

"Monsieur. He's on the move." Yuga informed as everyone turn their attention back to the monitors.

(Training Building, with Izuku and Katsuki)

Katsuki is getting ready to launch himself toward Deku with his explosion as the latter was able to see that quickly as he warns Ochaco to run which she did just time as Katsuki exploding-dash at Deku and swing kick to the head though he blocks it with his arm.

"Ballsy move, think you can take me on alone?" Katsuki asked, then he gasp upon seeing Izuku not only block his kick, but he is also using the capture tap wrapping on his leg.

"(Hero notebook number 10, page 18! Luckily, I got to see Eraser Head's move in action.)" Izuku thought recalled seeing Aizawa using his capture scarf on Katsuki yesterday.

"(What will Kacchan do now? Knowing him, he'll be impatient and try another big punch!)" Izuku anticipated as he dodges Katsuki's explosion punch with his right hand and grabs it.

"Time to try out a move I've been working on with Medaka's help." Izuku said and jump, bending both legs and aiming his feet at Katsuki channeling 5% of One for All into them.

"Kangaroo Smash" Izuku kicked Katsuki away crashing into a wall on the right and on the floor.

Thanks to the years to studying different heroes with quirks and figuring out different strategies, plus all the training he did with All Might and Medaka paid off as he was able to land the first hit on his former childhood friend.

"(He kicked first, that means he's trying to be unpredictable so I can't figure out his next moves.)" Izuku thought figured what Katsuki is trying to do.

Katsuki gets up with his usual angry expression as he is about to attack Deku again.

"10% Delaware Smash" Izuku fired an air blast knocking his opponent off his feet and back slam into a wall. Glad he got the idea of using a higher percent of power for an instant during his training with Medaka.

Izuku quickly starts running into a different hallway to lose Katsuki in confusion making the hallways of this floor into his own maze.

"Don't you dare run from me!" Katsuki shouted chasing after him.

But Katsuki could not find no matter which way he went as he got angrier and angrier by the second.

"DAMN IT! You were tricking me for years by acting weak. Bet you and that blue-bimbo bithc of yours have been laughing behind my back, huh?" Katsuki shouted assuming he is being mocked.

(Monitoring Room)

"Bimbo?" Medaka repeated as the cowlick stand up straight in respond to her angry.

"Just because I have big breasts doesn't mean I'm dumb, I'm plenty smart, thank you very much." Medaka pouted and cross her arms under her breasts.

"Uh, how do you even know what he's saying when we can't hear the video?" Momo asked.

"I read his lips, I learned how to do that from a book." Medaka answered honestly.

"There's a book on how to read lips?" Sato surprised.

"Whoa, that Bakugo guy sure is angry. Kinda scary…" Denki pointed out seeing Katsuki in rage and small explosions erupts from his hand.

"(Midoriya tells me that Young Bakugo thinks very highly of himself, but this level of pride is something else. It may end up being his demise.)" All Might thought seeing Katsuki enters an empty room trying to find Izuku.

(With Izuku)

Izuku laying low for a while trying to think of a plan to beat Kacchan to capture him as he knew he would come after him instead of Tenya who is faster and could've captured us, he can also tell that Katsuki and Tenya aren't working together which can work in their favor. Knowing if both he and Ochcao try to take on Katsuki together than they would run out of time, and both going for the weapon would make Katsuki come after them. Meaning he'll have to trust her to find the weapon and Tenya and hopefully catch up to her quickly as he can, but that's easier said than done as the exploding boy isn't going to be easy to take down even with using 5% of his Quirk.

Meanwhile, Katsuki is thinking back to how Deku suddenly gotten so confident in himself and thinking back when they were little kids that he accidently slips on a log and fell into a little river that was shallow. He was find, no serious injuries or anything, but he also remembered when Izuku came down offering his handing hand to him and said the words that ticked him off.

"Are you all right? Are you hurt? I was worried you might've hit your head or something."

"(I was fine, I didn't need anyone's help. But you looked at me like I was some kinda weakling.)" Katsuki thought recalled and member what Deku also said during the sludge incident.

"Kacchan. I couldn't just stand here and watch you die!"

"(Like you, but I'm not! I'm so much better than you are!)" Katsuki thought proclaimed and will prove to him once again who's number one around here.

(With Ochaco)

Ochaco managed to find the weapon and Tenya guarding it as expected, now all she has to do it inform Deku and stay hidden until he gets up here, but before she could call him, she hears Tenya saying something.

"Bakugo definitely has a villainous side and that's exactly what we need to succeed in this mission. I need to temporarily devote myself to criminal intent." Tenya said to himself, even though he doesn't like doing it, but he won't bring shame to the Iida family name.

"Behold! I am the personification of villainy!" Tenya started acting like a villain with a creepy tone and a laugh.

(Monitoring Room)

"HAHAHAHAHAHA?! That is the most funniest thing I have ever seen!" Medaka laughed as she drops to the ground.

"I have to admit, he does seem kinda weird to be acting like a villain." Minoru pointed out as Koji and Kyoka try to hold in their laugh.

"It would seem that Uraraka have out herself be spotted, now she'll have to fight Tenya." Momo stated seeing Ochaco and Tenya now facing each other and notice the time is six minutes and thirty seconds.

"Oh look, Bakugo found Midoriya!" Mina pointed at the monitor screen showing Izuku and Katsuki facing each other.

Medaka notices one of Katsuki's gauntlets lit up red for a second.

"That doesn't look good." Medaka worried.

(With Izuku and Katsuki)

"I'm all loaded up." Katsuki said.

"What does that mean?" Izuku asked, being caution.

"That fancy Quirk of yours is pretty strong, but it looks like you don't have complete control over it and that means you're screw if you go overboard." Katsuki smirked.

"(Damn, he figured me out.)" Izuku thought shocked.

"(But even so, I have to face him head on!)" Izuku thought said standing his ground as he ready the capture tap.

"Kacchan, I'm not scared of you anymore." Izuku determined.

Katsuki growls a little but then he smiles.

"Since you're such a stalker, by now you probably know how my Quirk, Explosion, works. I secrete nitroglycerin-like sweat from my hands and make it blow up. Imagine what I could do if I had a lot of it." Katsuki explained as Izuku gasp figuring out what those gauntlets are for.

"That's right, these gauntlets aren't just for show. They've been storing up my sweet inside for one monster blast." Katsuki explained as he put his finger in the pin.

"Young Bakugo! Don't do it! You'll kill him!" All Might warned in the earpiece.

"He'll be fine as long as he dodges!" Katsuki smiled crazy and pulled the pin unleashing the large explosion blast at Izuku.

Izuku quickly channels One for All into his legs again to dash fast to the door at the end of the hallway and quickly open into a large room letting the explosion blast past, but he still got blown away by the shockwave.

"(Is that even allowed!)" Izuku thought gasped as the blast cause a hole in the building.

(Monitoring Room)

"Whoa, this is nuts!" Eijiro said as the shockwave have reach this room.

"Izuku, please be okay." Medaka prayed.

"I'm sure he'll be fine, Medaka. You did told how tough he can be." A voice said causing Medaka to gasp.

"Ah, you must be our two missing students. Welcome." All Might welcomed them.

"Ah! Zenkichi and Shiranui, you're here!" Medaka smiled, seeing her old friends again.

Zenkichi is of average height and build for a fifteen-year-old, with strawberry-blond hair and blue eyes. His hero costume is a hybrid of modern, futuristic and old features. He wears a white sleeved jacket with two long thin tails hanging from the back. Under it is a black shirt with three red belts and also several belts covering his right arm. He wears a pair of black gloves with a blue shell on the backs of the hands. He wears a black hakama and steel-toed red boots.

Shinranui is has blue eyes and blue hair, with a curled ahoge on top of her head. Despite starting in high school, Shiranui has a very childish appearance. Hero costume is a ninja style clothing in pink clothing and on her back is a katana with the sheath, and her ninja mask is hanging on the back as she hasn't put it on yet.

"Hey Medaka, sorry we couldn't make it yesterday, but I heard our homeroom teacher is very strict." Zenkichi greeted.

"Yes, but he does care for others in his own unique way." Medaka nodded.

"I'll be the judge of that, but I'm pretty surprise that the explosion didn't destroy the entire building." Shiranui pointed out.

"Oh, that's right!" All Might remembered the fight.

"Bakugo, use that stored-up power again and I'll stop this fight. Your team will lose." All Might warned making Katsuki question this.

"To employ such a strong attack indoors is inviting the destruction of the stronghold you should be protecting. That's a poor strategy, whether you're a hero or a villain. The penalty would be massive loss of points." All Might explained.

"Your dad seems to be doing well on his first day of teaching." Zenkichi commented.

"He is though he had some help getting ready." Medaka said.

"But shouldn't he stop the fight since it gone out of hand?" Zenkichi asked.

"I'm sure father wants to how these boys will do on their first hero training." Medaka stated.

"(But I also believe he wants to see how his successor will do in a fight like this.)" Medaka thought as either her two old friends knows about All Might's secret since she has promise to never tell anyone, not even her closest friends.

"Looks like they're gonna fight hand-to-hand." Shiranui informed as she licks a lollipop she pulled out from her sleeve.

(With Izuku and Katsuki)

While Katsuki gets angry that he could use his new blast with the gauntlets, Izuku tells Ochaco the plan hoping that it would work and get ready for the fight.

"We'll fight hand-to-hand!" Katsuki roared as he launches himself at Izuku.

Seeing he's coming at him fast, Izuku clutches his right hand channeling his power and throws the punch at Katsuki, but he made a small explosion at the fist to jump over Izuku in midair going behind him and blast him in the back. However, at the same time Izuku manages to swing his leg to back swing kick Katuski on his stomach, the attack didn't hurt much but the force still pushes him to hit his back against a window.

"Damn nerd! Here comes the famous right hook you were wincing about!" Katsuki shouted, blasting him at Izuku faster than he could react and smack his left arm.

Katsuki grabs Izuku and use the explosion to move around him.

"Don't you ever forget who you are: you're a weakling!" Katsuki shouted and shoulder throw him hard on the ground causing Izuku to gasp.

Izuku quickly move his left hand in front and blast a Delaware Smash sliding him between Katsuki's legs and stop close to one of the windows.

"You really piss me off, Deku. You've been hiding your true power for years, you probably told that girly Might bitch that I was an idiot, thinking you're better than me this entire time!" Katsuki angered.

"That's what you think." Izuku muttered, thinking back on their childhood everything they did despite the broken bond they have. "You idiot."

"You've always been stronger, Kacchan. I know you're better than me." Izuku confessed as Katsuki grunts.

"Can't you see? That's why I want to beat you because you're amazing!" Izuku shouted.

"You're even more of an idiot than I realized. Come at me!" Katsuki taunted and the two charge at each other

Seeing no other way, Izuku charges up his right arm with One for All at 100% while Katsuki ready his strongest explosion.

"Detriot…" Izuku ready to unleash his attack.

(Monitoring Room)

"They're going to kill each other! Sir!" Eijiro begged All Might to stop the match as he wants to end it too.

"Don't even think about it, father." Medaka said, shocking the students.

"Are you crazy, don't you want your boyfriend to come out alive?" Rikido gasped.

"Of course, I do. Which is why he's going to win!" Medaka determined.

(Training Building)

"Uraraka, now!" Izuku shouted, Ochaco got the single and held tight on a pillar for the plan.

"(I can't beat you, not in a one-on-one fight like this. But I can win.)" Izuku thought moved his arm into an uppercut position.

"Smash" He launched the uppercut creating a powerful wind pressure going through each other and through the roof.

"What's happening?" Iida shocked seeing everything floating by the air pressure.

"This is it! Sorry, Iida!" Ochaco picked up a broken pillar using her Gravity Quirk.

"Improvised special move: The Comet Home Run" Ochaco swing the pillar hitting some of the debris flying at Iida.

"In the name of villainly, I demand that you stop this"! Iida said as he braces himself.

However, he failed to realize that the attack was just a diversion as she made herself float over him and latch onto the fake weapon.

"I got it." Ochaco sighed in relief.

"No! The weapon!" Iida gasped.

"This was your big plan, wasn't it? …From the very beginning. You were playing me this entire time, you bastard." Katsuki shocked.

"I… I can't control my Quirk. Just as you said, my body can't handle the backlash of my power yet. Mr. Aizawa said that I'd be useless… but this was the only chance I had at winning." Izuku said as his left arm is burned from blocking Katsuki's blast.

Katsuki gasp of realizing that he has been beaten.

"The Hero Team Win!" All Might announced.

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

Man, that battle was intense that Izuku barely got out of there without a scratch and some burn marks, but he managed to win the training exercise and beat Katsuki shattering his pride. Hope you like Zenkichi and Shiranui appearing in the story as two of the mission students and the next battle will be them vs Medaka and Mogana as they will show their might as well.
