AN: As much as I would enjoy a large scale Class A vs Class B, it's really difficult to write action scenes which incorporate many people at once. So I cut it down to only a few. That's not to say that those not involved aren't important.
"And why would they pick a fight with us? It's Bakugou who's always shit talking!" Kaminari twiddled his fingers.
"Because Class B is weak as shit! Now they've suddenly powered up and think they can beat me?!" Bakugou only helped enforced Kaminari's words.
"Hey, Kendoooo." Iida attempted to call out to his fellow class president of the opposing class, who always styled her orange hair in a ponytail. Iida frantically waved his hands to get her attention.
She turned to her head, taking notice of Iida. She stood there awkwardly, with a twitchy snarling expression which was very uncharacteristic of her.
"Please, help me. Help all of us." Kendo's thoughts were nothing like the expression she was portraying to the Class A members that were present.
"Yeah she's not talking. None of them are, weird." Kaminari observed, "But if they won't tell us what's going on then I'll make them!"
"No wait! We should think of a plan!" Midoriya called out to Kaminari who charged forth on his own.
"I still can't control my powers so everyone take cover! I'll take them out in one go."
Kaminari charged solo into the fray, electricity surged through his body until it shrouded his body.
"1,000,000 Volt discharge!"
Shiozaki, the girl with vines for hair, simply used her vine quirk to block and nullify the attack. Kaminari's electricity stopped and all Class A could see was a giggling idiot with his thumbs up.
"Whrrrry."
"Pft. What an idiot. He just repeated what happened during the sports festival." Jirou held back her laughter. Kaminari's expression after exceeding his wattage limit always made her laugh no matter the situation.
"But I don't think he's okay!" Uraraka pointed out as Shiozaki then swung her thorny vines to wrap Kaminari up.
"Full Cowl!"
"Blast Rush Turbo!"
Midoriya and Bakugou used their respective quirks to save Kaminari as quickly as possible before the vines got a hold of him. But coming from two different directions, the two collided as they grabbed a hold of him. Now Kaminari, Midoriya and Bakugou were surrounded by the mob of Class B students.
"You fucking idiot! I had it!"
"S-s-sorry!"
"Ah, forget it. Get this giggling dumbass outta here."
"Huh? That's it?" Midoriya was shocked, usually Bakugou would ramble on and on about everything he did wrong.
"Do you need me to write out instructions? Because it's really not a good time."
Bakugou focused his attacked into successfully blasting Shiozaki's vines away.
"No. I'll leave this to you. Just make sure to lead them away from the dorm so it doesn't get destroyed."
"Yeah."
"And Shiozaki's vines are weak to your explosion. Tetsutetsu's quirk also doesn't fair well against heat. Monoma copies quirks. Kendo's fists get larger. Other quirks from Class B are weld, solid air, size-"
"Shut up Deku I don't need your advice and don't act like we're partners. Just hurry up!" Bakugou let out an explosive discharge as a smokescreen for Midoriya to escape with Kaminari using Full Cowl.
"Young Midoriya, young Bakugou. If you recognize each other's strengths and weaknesses, you two can become heroes who both win and rescue."
"Tch. Bullshit." Bakugou recalled the words that All Might spoke of the night he learned about One for All.
Todoroki summarized his meeting with All Might to Shinsou who had met up with Todoroki so that they could discuss their next actions as vigilantes. Shinsou looked in the distance at a figure resting underneath a tree. The student had been staring them down for a while now.
"Todoroki, isn't that person Juzo Honenuki from Class B? Did you do something to him?"
"What? I've never even talked to the guy. All I know about him is that he got into Yuuei through recommendations like I did."
"Then why does he keep staring? Wait…what if he's the spy…then he knows we've been snooping around looking for a spy?"
"Haha, no way. That would be too easy…"
After Todoroki's unsettling chuckle, the two simmered down. They had both unintentionally entered a staring contest with Honezuki and carefully approached him. What if, just what if Shinsou's suspicions were true? What if Honezuki was the traitor. His face fit the part, he had a skull-like appearance after all. They kept walking until they were close enough to initiate conversation with him.
"Hey, Honezuki. What's up man?" Shinsou broke the silence.
"Grhhhh." Honezuki only grunted. It wasn't a proper response that could be affected by Shinsou's brainwashing.
Honezuki, like the majority of Class B had been forced to take Trigger against their will by the real traitor.
"I don't like the look in his eyes." Shinsou commented as he backed away slowly.
Honezuki stomped one foot which turned the ground around them into a quicksand texture thanks to his Softness quirk. Todoroki jumped and placed ice below him so he wouldn't be trapped in the quicksand.
"Me neither, that's the look of someone who has taken a dose of Trigger."
"This is bad."
"I know. If he got in through recommendations, then he's going to be formidable opponent."
"No I mean, this is bad. That means his quicksand is stronger." Shinsou couldn't avoid Honezuki's previous attack and was struggling to get out. "So, a little help here?"
"Sure, if I'm on Yuuei grounds, I can freely use my quirk without punishment. I'll finish this up as fast as possible."
Todoroki sent a surging wave of ice at Honezuki, hoping to finish it quickly by instantly freezing him. Honezuki's softness originality can only activate when he touches anything. But with the Trigger enhancing his quirk, softness could now be materialized as energy and emitted to anything it touches. Honezuki used his quirk against Todoroki's ice, making it as soft as water which Honezuki easily sliced through with his arm.
"Seriously? He just turned your ice into water!"
Todoroki kept throwing ice at Honezuki from all angles but he'd just soften the ice and end Todoroki's barrage of attacks.
"He keeps defending and Shinsou's running out of time." Todoroki had to back away from fighting. He clapped his hands and then slammed his palm to the ground.
Todoroki tried to freeze the quicksand it was formed solely from Honezuki's quirk interacting with the grassy terrain beneath them. When Todoroki's ice came into contact with the quicksand, it just turned into softened, watery ice like all of Todoroki's previous attacks.
"T-th-that just made things w-w-w-worse!" Shinsou shivered as he was caught up in a freezing, wet quicksand texture. "J-j-just use your o-other s-side! I-it's getting worse. H-he can't soften fire."
Todoroki prepared himself to use his left side but he couldn't even surround his arm with flames. He had slowly become comfortable using his fire quirk again but all that changed when he fought Yoarashi, used Blazing Tokyo Smash, setting a building on fire and worse, accidentally setting an innocent person on fire in the process. Sure, Todoroki used his fire side as Yukihira but only to melt his ice. He had always been afraid to use it again after the incident which caused his suspension. Todoroki learned how harmful boiling water could be as a child. And so, from the incident could only imagine the pain from being set on fire. Todoroki lowered his left arm and continued sending larger waves of ice towards Honezuki, hoping he'd tire out.
"What are you doing?! Ice won't work against him you- no way…he's afraid to use his left side again? I thought the only reason he became an ice quirk vigilante was to hide his identity." For Shinsou, the quicksand had sunk him down to his chin. It was only a matter of time before Shinsou would drown in the quicksand.
"It's no longer matter of my father's legacy over me. But, what if I severely burn Shinsou in the blast? Or Honezuki?" Todoroki's couldn't stop his left arm from shaking uncontrollably. "Hey Shinsou, this seems unnatural. With Hideo's sight speed, for the most part, he had control of his consciousness. But with Honezuki, it's like he's been injected with an earlier phase of Trigger like the one used on Yoarashi. It's favors the traitor if the students use an unstable version of Trigger. So this could be a ploy by the traitor…which would make Honezuki innocent. What do you think, Shinsou?"
Todoroki glanced over at the quicksand as he finished verbalizing his theory and there was no longer any sign of Shinsou.
"Shin…sou?" Todoroki hoped that he'd receive his typical snappy comebacks. But there was no response to his question.
Todoroki's left arm rapidly shook until it came to a sudden halt.
"If I didn't stop Yoarashi, there may have been a chance that he'd harm other people. There may be precautions to ensure there isn't significant damage. But in the heat of the moment, heroes can't always perform their duty flawlessly. And if I had to choose between burning one person who'd live through the pain or a chance of Yoarashi targeting other civilians, sorry, but I'd have that person burning every time. If I had to choose between saving someone's life or having them die, I'd save them every time."
Todoroki covered his entire left side in flames and his entire right side with ice.
"There's no telling if he'd be able to stop my flames or not. So I send both at him. I'll live with the consequences. If I want to win, if I want to save Shinsou then I'll go beyond.
Todoroki fired out waves of ice on one side and hungry, roaring flames on the other Honezuki. The attack was powerful enough to cause cracks on the ground that they stood. And covered enough ground that Honezuki had no choice but to defend against Todoroki to the best of his ability.
"Plus Ultra!"
Honezuki's softness was helpless before Todoroki's fire and ice quirk. On one half of his body was the pain of being burned by fire and on the other, being frozen by ice, a feeling that Todoroki's body was familiar with. After Todoroki's attack had cleared, Honezuki had become burned on one side and frozen on the other. The blast caused Honezuki to lose consciousness and collapse on the ground. The quicksand had stopped and the ground turned back to normal.
"Hup!" Todoroki destroyed the land beneath and freed Shinsou who immediately gasped for air and started coughing uncontrollably.
"Shit shit shit! That was a close one! Thank you VERY much." Shinsou still gasped for air. He was on the verge of death after all.
Todoroki smiled with relief on his face, he gave thumbs up to Shinsou, "Heh. You're welcome." Todoroki legs went limp from exhaustion.
"H-huh?" Shinsou had managed to calm down a bit and tried to pick up Todoroki, but was too heavy for him to lift up, especially after tiring himself out from struggling in the quicksand. Instead, he put a resting Todoroki against a tree filled with lots of shade. "Hold on, I'll head to the dorm and get someone to tend to you."
"Deku can rescue all he wants! I'll be the one that wins! Hahahahaha!"
"Geez, doesn't Bakugou ever tire out?" Jirou movements looked sluggish compared to Bakugou's but she was trying her best to fend off some of Class B.
Midoriya took his time to analyze the situation and odds of winning against Class B, "Kirishima and Kaminari are unable to fight. Everyone else is busy with their internship or something else. So right now we have me, Uraraka, Bakugou, Iida, Jirou, and Yaoyorozu. Half of us here have a utility based quirk. The other half is more suited for combat. We're up against Class B, who seems to be abnormally stronger than they should be."
Bakugou had failed to lure them completely away from Heights Alliance. Though still in sight, the battle would be at least quite a distance from the dorms and on open grassy plains. Yaoyorozu had volunteered to stay in the backlines as the last line of defense, creating barricades and defensive cannons to keep out any intruders. However, it didn't seem that Class B would reach Yaoyorozu. Most of them had already been taken out. The only ones remaining were Shiozaki [Vine], Tetsutetsu [Steel], Tsuburaba [Solid Air], Monoma [Copy] and the class rep Kendo [Large Fists].
"Leave the poor man's Kirishima! He's mine!" Bakugou was eager to avenge Kirishima, who had been knocked unconscious by Tetsutetsu.
"Kacchan, I think we should work together to take them down. It's been working out so far. There's no need to split off into 1 on 1s just because we can." Midoriya did his best to be rational with his childhood friend, but already knew how he'd respond.
"Fuck off! Like hell I'd work together with you!"
Bakugou continued on to isolate Tetsutetsu but Monoma who was previously fighting with Iida and bore a grudge against Bakugou, left Iida alone and followed suit. With Bakugou at a numbers disadvantage the rest of the class tried to jump in but were blocked off Tsuburara's large wall of solid air and Shiozaki's thicket of vines.
"This is bad…" Despite knowing how capable Bakugou was, he still worried for him in this situation.
"What's wrong, Deku? It's Bakugou we're talking about!" Uraraka tried to lessen his worry.
"Yeah, but…if we're talking about the current threats, Monoma might just be the biggest one here."
Bakugou was trapped in close quarters combat with Tetsutetsu, who reinforced his hands but turning one hand into a thick jousting lance and another into a shield. Bakugou parried the attacks and countered with an explosion but no matter how hard he tried, Tetsutetsu wouldn't allow Bakugou any distance.
"Get away!" Bakugou turbo boosted himself into the air and kept his explosions going to keep himself from landing.
Monoma, copying Bakugou's power, turbo boosted himself towards Bakugou, tackling him to the ground. Tetsutetsu aimed to stab Bakugou with his jousting lance.
"Argh, you're both so annoying! Just because you've gotten a little stronger, doesn't mean I've become any weaker."
Bakugou kicked Monoma off and dodged Tetsutetsu's attacked.
"A little stronger? I think I've become much stronger." Monoma had uttered the first words from anyone in Class B. The entire time, they had stayed quiet but Monoma broke the silence. "Before I could copy two but only use one at a time." "But thanks to that person injecting me with that drug."
Monoma, having previously been fighting Iida, copied his quirk and revved the engines on his legs and combined them with Bakugou's Blast Rush Turbo to run incredibly fast. It was too fast for Bakugou to react accordingly. Monoma dashed from where he stood, to Bakugou and landed a clean punch to the gut.
"Yeah, Bakugou's in trouble." Jirou clapped her forearms together, injected her earphone jack into them and created a powerful sound wave that broke through the wall of solid air and vines.
"I'll save him!"
With a clear path, Iida rushed over to Bakugou's side to even the odds, Iida ran fast enough that Shiozaki, Tsuburaba, Kendo, couldn't stop him.
"Haha, wow you're slow. Aren't you the original?" Monoma looked at Iida with contempt.
Thanks to the addition of Bakugou's quirk, Monoma's engines allowed him to move at a higher speed than Iida.
Using Tetsutetsu's power, Monoma turned his hand into the tip of a blade and charged over to stab Iida.
"Iida watch out!" Uraraka cried, hoping he'd dodge it in time. "Why did Iida run off on his own? I know he wanted to aid Bakugou but…now…now…" But it seemed like Monoma had the advantage over Iida.
"Can I make it in time with Full Cowl? Even if I use 100% it still might not be enough. But if I had to choose between trying and not trying, obviously I'd try my hardest!"
"You idiot Iida, I didn't clear a way just so it could end up like this." Jirou's fired another sound wave, hoping it'd reached Monoma before he could stab Iida.
Monoma stabbing Iida seemed like a sure thing to happen and the members of Class A felt helpless as they all rushed over to stop Monoma. Meanwhile, someone had requested Yaoyorozu to create a megaphone which she gladly complied to.
"You sure do talk a lot, for someone using Trigger."
"Hah?" Monoma shouted back to the voice that he heard over the megaphone but the second he did, he froze up, unable to move, unable to stab Iida. Iida took this opportunity to get some distance between him and Monoma and to run over by Bakugou's side.
"Who?" Midoriya, Uraraka and Jirou all stopped in their tracks and responded to the voice.
"You know, I was surprised to see that it wasn't just Honezuki, but all of Class B who had been injected by Trigger. More so, that someone could talk after they've been injected. But it's a good thing you can talk or my quirk would just be useless."
Midoriya looked at the person who Yaoyorozu had created a megaphone for, Hitoshi Shinsou, the student with the brainwashing quirk stood before them all. His voice was faster than anything else on the battlefield, enough to stop Monoma from harming Iida. The megaphone had amplified the reach of his brainwashing but made it more unstable. In doing so, it left Midoriya and Uraraka in a dazed state but strangely, Shinsou's brainwashing was incapable of affecting Jirou who still had continue of her body.
Shinsou continued to raise his voice over the megaphone, "Neito Monoma was it? Consider this an order. You are to remain still until we kick your ass."
