Rival Clashing with the Enraging Past!

Sayo is doing a health inspection with one man on the hospital bed and just inform him that he is now full recovered, and he will be able to leave tomorrow morning.

"Thank you for helping me, Nurse Sayo. I thought I was gonna be here for a while longer." The old man with a pink bread thanked the nurse.

"Well, the results have been checked in and everything is all green! Now, you just have to make sure to be careful with what you eat from now on even though your Quirk allows you to eat almost anything." Sayo advised.

"Right, guess mixing metal and brick with some pasta and hot sauce wasn't a good idea to test out my Quirk a little." The pink-breaded chuckled with his cheeks blushing of embarrassment.

Sayo leaves the room to go turn in the paperwork on the patient but then stop at one window looking out in the direction of the UA High School, thinking about her precious little brother who is doing Hero Training with All Might right now to learn about what it means to be a Pro Hero.

"I bet Izuku is doing great in class right now!" Sayo smiled.

"No doubt he is blowing everyone away, and probably making Katsuki super jealous." Sayo chuckled.

"That exploding kid is probably screaming at Izuku angry by now, I wouldn't be surprise if they were doing combat training right now and fought against each other." Sayo said before walking in the hallway again.

(Izuku vs Katsuki)

"TAKE THIS?!" Katsuki charged in throwing a downward explosive punch.

Izuku was able to react fast by ducking under the punch while getting to his rival's backside that is the blind spot of all men, he reels in his right leg and throws a kick to the back hoping to send him down.

However, Katsuki was able to see that coming and counter with a thrust kick of his own that collied with Deku's and they push each other away.

"Don't think you can get me that easily, Deku!" Katsuki glared.

"I know, but that doesn't mean I won't stop trying!" Izuku said as he got into his fighting stance.

"Then I'll make you stop by breaking your damn brain!" Katsuki threatened.

Katsuki use his explosions to run on the wall fast then jump off for a kick to the head that Izuku was able to block with his arm, he can feel the strength behind that kick and was able to push it off with some force and jumps after him for a punch to the face only for Katsuki to block it with his gauntlet.

Katsuki growls as he pushes his gauntlet blocking the punch over to the nerd's face to finally land an explosive punch to the face knocking Izuku down on the floor.

"Now Die!" Katsuki shouted as he blasted himself down with his right leg to smash on his head.

Izuku quickly rolls out of the way and flip himself backward to get back on his feet though Katsuki still kept on the attack as he charges forward to throw some explosive strikes, Izuku holds up his arms to block the strikes and stepping back a few feet.

"(Kacchan is still going aggressive, but that's what makes him focus on the mind too which makes him fiercer.)" Izuku thought gritted his teeth.

He saw that the exploding boy is about to throw another strong hit only for that arm to be thrown off when Deku threw his arms open, this gave him the opening to throw a punch on Katsuki's face sending him flying back over twenty feet away.

"You ready to surrender now, Kacchan?" Izuku asked.

"Not on your damn nerdy life!" Katsuki shouted in rage as he got back up.

"Then… Bye!" Izuku dashed away from the scene and into one of the path of the floor.

"Hey! You're running from me, you damn nerd fucker!" Katsuki shouted in both shock and rage at the same time.

"Just because you were lucky enough to finally get a damn strong-looking Quirk that you're better than me now? Think you're the more special one to outshine me?!" Katsuki shouted in anger and frustration of seeing how strong that damn Deku has gotten now.

While hiding in one of the hallways, Izuku heard what his exploding childhood friend and rival was shout about that causes the green boy to clutch his fists and feel a little bit angry.

"Let' see how it compares to mine! Quirk or no, you'll never beat me, Deku!" Katsuki proclaimed with explosions in his hands.

(Monitoring Room)

"That guy has some real anger issues, kind of scary…" Denki commented.

"Yeah, it's almost like he's a rampaging beast than a villain. I hope Tsu and Deku will be okay." Ochaco concerned for those two.

"I wouldn't worry about it, the boy maybe extreme, but I doubt he'll go far to get himself kick out of UA." Kyoka stated twirling her Earphone Jack on her finger.

"Still wish he tones down the exploding attitude." Mikoto said.

"I don't know, I think the exploding mood is one of his best features since I'm also an exploding Quirk type." Oriha said.

"(The Midoriya family told me that Young Bakugo thinks very highly of himself and Yuuko is the one who puts him in his place if he goes a little too high. Still, this level of pride is something else.)" All Might thought recalled a talk during the ten months of training.

"(Yuuko also warned me that his pride may end up being his demise if Young Bakugo isn't careful.)" All Might thought as well.

(Back with Izuku)

Izuku is panting a big while looking over to see that Katsuki hasn't found him yet though he can tell from the big sounds of explosions that he is still looking for him.

"(Good, he's completely forgotten about my partner. Just like I thought.)" Izuku thought glad that his plan is working.

"(If they wanted to send someone out to stop us here, they should've send Iida. He's way faster, after all.)" Izuku thought stated of Tenya's speed being difficult to avoid.

"(That probably means Kacchan's gone rogue. The two of them aren't working together as a team.)" Izuku thought realized as he knows Kacchan well that he doesn't work well with others.

"(If we had to take those two on head-to-head our chances of winning would be probably be close to 50%, but that would still be a low chance since they got such strong Quirks.)" Izuku thought stated.

Izuku does some thinking about this situation and the plan the hero team came up with together before the start of the match.

"(I can't go after the weapon right now or Kacchan will follow me.)" Izuku thought knew that even facing both Tenya and Katsuki at the same time would be difficult, and there is also the fact that Tenya's speed would catch Tsuyu as well.

"(And if both take him on, we'd probably only have little time left to find the bomb though Iida would try to be prepare for us to make the time run-out on us.)" Izuku thought of the second scenario.

"(So, we stay split up for now. I have to trust Tsuyu, she'll find the weapon and Iida, and then I'll join her for a two-on-one fight after I beat Kacchan down here. That's the only way to win.)" Izuku thought believed of this plan.

"(I can do it. As long as I'm can avoid his explosions and land some good hits, we'll win!)" Izuku thought determined.

"Come out and face me, you coward!" Katsuki called out angry.

"(By the way, Kacchan, about what I said that I wasn't competing against you… I take it back.)" Izuku thought readied himself.

Katsuki is still walking in the hallway with an expression of rage because of how strong that damn Deku has gotten over the months since middle school, and to think it was even possible for him to get his Quirk at that age making him the latest late bloomer according his Pro Hero mom which she knew more since she's also a doctor.

"(To think that little bug would get this far.)" Katsuki thought.

"Wow, you're so awesome!"

(Over 11 Years Ago)

"Whatever, this is nothing." 5-year-old Katsuki grinned while bouncing a ball showing this to 5-year-old Izuku.

Little Izuku tries to bounce the ball on his head but couldn't and got an owie.

"You really can't do anything right, can you?" Katsuki chuckled.

"Maybe not, but that won't stop Izuku from having fun." 11-year-old Sayo stated smiling and starts bouncing the ball using only her head.

"Wow!" Izuku and Katsuki impressed.

Next scene shows Katsuki holding a bucket with Izuku's name and pointing at one kanji.

"Look! You can read the last part of Izuku's name as "Deku"." Katsuki tapped on the kanji, impressing the other kids that he can read it.

"Deku, that must be what you call a helpless loser who's completely useless." Katsuki mocked.

"Why are you being so mean, Kacchan?" Izuku asked a little sad.

"That's only half right, Katsuki." Yuuko walked up to the kids much to little Izuku's joy.

"You see, the word "Deku" is one that can mean in both ways like the useless one you mentioned can be a pun word for "Dekunobou" but the other word for Deku can also for "Dekiru", someone who can do anything." Yuuko explained while writing this down with a pink chalk.

"So, even when you start calling Izuku "Useless", you're also calling him someone who can do anything at the same time." Yuuko stated with a smile.

"Whoa!" The kids are impressed as Katsuki is surprise to hear that one word could mean two different things at once.

"Really? I can do anything?" Izuku asked.

"Yes, as long as you have a strong heart then nothing will keep you down." Yuuko nodded.

"I actually believe you when your mom said that, about you can actually do something." Little Katsuki thought.

Little Katsuki and Izuku continue playing together with some other kids only for the former to show off his own talents like stone skipping and other games, then the day came when Katsuki got his Explosion Quirk that everyone started praising him and giving Katsuki the thought of no one being as great as him.

But when the day came when Izuku turned four, he didn't get his Quirk at all leaving him Quirkless that got the other kids to mock him including Katsuki thinking of him as a failure.

"You're a failure, Deku."

"That's it, you're getting it now, Izuku!" Sayo clapped her hands seeing her little brother bouncing the ball on his head though only for a little while.

"The heck are you doing, Deku. Don't you know how stupid you are by trying?" Katsuki mocked with the boys.

"And what's wrong with that? Izuku has been getting better at it, saying him being a useless Deku can also mean he is useful like our mom said." Sayo stated.

"Yeah." Katsuki rolled his eyes not believing anything this girl says, but Sayo just punch him right on the face.

"You better start being nicer to Izuku or else you'll be schooled in bed for a long time." Sayo cracked her knuckles.

"Sayo, no! Don't hurt him!" Izuku stood between Sayo and the downed Katsuki.

"Yet despite that, you defended me like I was weak."

Next scene shows Izuku and Katsuki playing together, but it's more of a one-sided play with Katsuki taking the toys and playing them for himself.

"Come on, it's my turn!" Izuku begged.

"Yeah, you can play after you get a Quirk which is never." Katsuki laughed only for the little boy to get hit on the head by high heel.

"You know that toy wasn't even yours. At least start learning to share better." Yuuko scolded.

"Mom, it's okay. He just likes to play hard." Izuku defended Katsuki again which made him feel frustrated.

"You always do that just to make me feel weak like you."

Now there Katsuki leading the group of friends over a large wooden log with popping tiny explosions from his hand, but then he slip falling into the narrow river though he was just okay besides from being wet.

"I was just fine on my own, Deku."

"Hurry and get back up here." One boy called out.

"Sure, just gimme one second." Little Katsuki responded with a smile.

"I didn't need your stupid help."

"Are you alright? Are you hurt?" Little Izuku asked concern for his friend as he came down the slope to check on him.

"I was worried you might've hit your head or something. We'll have my mom check on you once we get back." Izuku said as he offers his head.

"It was bad enough that you were "worried" like I was weak like you, but you also had to drag your Hero Mom into it."

Little Katsuki started to change his face with looking at Izuku with anger.

(Present)

Katsuki continues walking a little more as he also starts to remember the words Deku said when that damn sludge villain got him.

"Kacchan, I couldn't just stand there and watch you die!"

"(Just you wait, Deku. You may have proven yourself to be strong now, but I'm still the top dog around here while you're below me!)" Katsuki thought determined with rage.

(With Tsuyu)

After searching through the floor since coming up here for a while, Tsuyu was finally able to find the weapon and Iida as well.

"(Okay, I found both the weapon and Iida on the fifth floor meaning we should be above Izuku and Bakugo.)" Tsuyu thought figured as she remembers the floor plans.

"(Iida doesn't appear to be doing anything at the moment which is good, I can call Deku about the location and wait for him to show as she can take him on together.)" Tsuyu thought reminded herself of the plan.

"Ribbit, this should be a piece of cake." Tsuyu whispered to herself softly.

But then she notices Tenya appears to be talking to himself at the moment.

"Bakugo definitely has a villainous side and that's exactly what we need to succeed in this mission." Tenya said to himself.

"I need to temporarily devote myself to criminal intent. Yes, I won't fail this trail and risk bringing shame down on the Iida family name." Tenya made up his mind on what he must do.

"That means… I must now embrace evil to become a hero!" Tenya declared.

"(I'm getting a weird vibe from this.)" Tsuyu thought wondered what Iida is gonna do.

"Behold! I am the personification of villainy!" Tenya started channeling into his inner villainy, and he sounds absolutely ridiculous right now.

"(…Wow, I didn't think Iida would be so serious of making himself look so bad.)" Tsuyu thought shocked with her face being blank and silence.

(With Izuku)

"Italy Smash!" Izuku threw a powerful kick that hit on Katsuki's side and send him away.

But Katsuki use his explosion to stop himself in midair and launches back at the damn nerd to grab is leg and send him spinning away, Izuku slide on the floor until he gets back up and ran into another path.

"Enough with the hit-and-run and fight me!" Katsuki shouted in rage.

Izuku is now hiding at the edge of a corner steading his breathing while looking over to see that Katsuki hadn't caught up to him yet.

"Deku, are you there?" Tsuyu contacted Izuku with the comm.

"I'm here, what's up?" Izuku responded.

"I found the bomb and Iida is with it, near the middle of the fifth floor that is right above you." Tsuyu answered.

"Good job." Izuku smiled.

"Iida is trying to act like a villain right now which is going horrible like monologuing." Tsuyu informed.

"(Okay, we still seem to have a little left time for us. About eight or seven minutes left at best meaning we have to finish this fast and hard, or they win.)" Izuku thought clutched his fists.

Izuku comes out of his hiding and ran around to find Katsuki who saw him as well, they both charge at each other clashing their arms and then Katsuki's right gauntlet glows red for a second with a ding sound.

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