Fury of a Fighter! Unbridled Power Unleashed!

"Let the final match begin!" announced Midnight at the top of her lungs. Goku and Bakugo immediately used their quirks to launch themselves at each other. The impact from where their arms connected blew a massive gust of wind throughout the arena. Both combatants had looks of determination on their faces with Bakugo's being the usual aggressive one. Yet for those who knew Goku they could tell something was off. His face while showing determination also showed an inner struggle. It was almost as if he was struggling to keep his anger from boiling over. Someone was more concerned than others.

"Uh guys I'm worried about Goku" muttered Jiro loud enough for the members of her class that were present to hear.

"Yeah come to think of it he was fine up until Kacchan's fight with Uraraka. His personality shifted a whole three hundred and sixty degrees after that" replied Midoriya who was analysing the quirks of both combatants and his friend's attitude. Goku's eyes showed pure anger where they once showed kindness and understanding.

"Something's up. Think he holds a grudge against Bakugo for almost killing you Midoriya?" asked Kirishima.

"Maybe. Kacchan's most likely made a bad impression" came the response from the green-haired boy. All eyes were on the fight and it wasn't looking like the match would be one of comradeship.

"KAIOKEN!" screamed Goku before launching towards Bakugo at an even faster speed than before. He pulled his fist back to connect it with Bakugo's head. He threw it and hit…nothing? Bakugo had vanished.

"What the?" said Goku as an explosion went off in his face and he went flying. He backflipped, landed on his feet and looked up to see Bakugo with his hands smouldering and his face wearing a villainous grin.

"That won't work on me. So get on with it. Get stronger. I'm gonna beat you at the top of your game" goaded the explosion loving teen. He placed his arms behind him with his palms open before setting of explosions, launching him forwards.

"DIE!" was all that was yelled as he closed the distance between him and Goku who simply looked him dead in the eyes. The aura around him grew more ferocious before expanding into the air.

"KAIOKEN TIMES FOUR!" yelled Goku before moving to the side to dodge Bakugo and throwing a kick which connected this time. The impact threw Bakugo away but he wasn't done yet and launched himself forward again with his explosions. This time as Goku dodged to the side Bakugo tilted his body the same way, catching his opponent off-guard with an explosion powered punch from his left hand which he had thrown forward. Goku's face took the full brunt of the attack and he went spinning in the air before being caught in a barrage of explosions.

"AAAAAAGGGGGGHHHHHH!" screamed Goku in pain as he was battered with burst explosions and the spectators could only watch as he howled in pain. His class started to sweat and looked worried. Eventually Bakugo ended his assault and watched with a grin as Goku plummeted to the ground. The impact created a small crater.

Goku barely managed to stand up before Bakugo came at him again. This time however Goku raised his right forearm to block the attack before returning in kind with a punch from his left hand to the gut of Bakugo. Bakugo winced and buckled in pain while Goku charged a massive ki blast in his left hand. He blasted Bakugo with it and while the teen was flying backwards Goku sped past him and kicked him in the back before speeding past him again and interlocked his fingers and raising his arms into the air. He then brought them down in a sledgehammer action, hitting Bakugo and slamming him to the ground. Goku then used his new flight ability to launch himself downwards with his right fist pulled back. He threw the punch only for Bakugo to block it and then swing his right leg up, catching Goku in the chin sending him spinning.

"Cute trick. Won't happen again though" admitted Bakugo as Goku stood up with the competitive fire in his eyes still very much burning.

"How the hell are you keeping up?" asked Goku as his body continued to strain under the pressure of Kaioken x4.

"Because I'm better than you!" gloated Bakugo. Goku's body tensed and he squatted into a familiar position. He started to growl and Jiro immediately realised what was happening.

"No! Goku don't do it! You promised you wouldn't! It'll kill you!" she screamed in despair. Her cries fell on deaf ears as Bakugo prepared to fight once more with him grinning at the circumstances.

"It's about time" he said under his breath. Goku launched his upper body backwards with his fore arms raised and his fists clenched.

"KAIOKEN TIMES TWENTY!" he screamed before the red aura burst into the air and momentarily blinded all present. The ground then cracked and Goku flew forwards with his fist connecting with Bakugo's chest who went wide-eyed due to the impact. Goku kept up his assault and pummelled Bakugo with everything he had. He quickly hopped back before uppercutting Bakugo into the air. Goku then disappeared from view before appearing above Bakugo and began to machine punch Bakugo straight into the ground. After his opponent was laying on the ground Goku stepped backwards and prepared himself for more fighting. Suddenly his face went wide in pain and he clenched his chest. Falling to one knee, Goku depowered back to his base state and began to breathe heavily. He looked up to see Bakugo slowly making his way back to his feet before turning to face him.

"Alright. Now I'm pissed!" yelled Bakugo and Goku could do little to stop Bakugo from striding over to him and grabbing his hair before lifting him to eye contact. Goku winced in pain while Bakugo just gave an evil grin.

"You'll never beat me. Not even Deku could beat me in a one-on-one fight. So what chance did you think you had?" he goaded before setting off explosions in the hand that held Goku's hair.

"DAAAGGHH!" screamed his victim in pain and the audience looked on in horror, unable to do anything. Using all his strength, Bakugo slammed Goku's head into the ground face first. After that was done he lifted him back up and saw that Goku's face was bloody but he was still conscious. Bakugo repeated the same attack but this time with even more force and when he lifted Goku back up he let go of his hair and threw an uppercut to Goku's chest before letting of an explosion which launched the exhausted teen into the air.

"HAHAHA! Time to end this!" announced Bakugo before raising his hands into the air with explosions sparking in his palms.

"DIE!" screamed Bakugo as a massive explosion ripped through the air towards Goku who could do nothing but take the blast head on. He had no time to even scream in pain as the blast enveloped him entirely. An enormous plume of smoke covered the entire arena and for the viewers at home all they could see was darkness. Bakugo smiled evilly and turned around triumphant.

"HAHA! TOLD YOU I WAS GOING TO WIN! NO ONE CAN STOP ME!" he yelled arrogantly with the audience not even sure whether to cheer or boo. Suddenly there was a loud crash and Bakugo turned around to see Goku on the ground. Still in bounds and most importantly still conscious. To say Bakugo was angry was an understatement. Bakugo was absolutely 100% livid. So livid that his eyes narrowed in anger, went pure red and he gave off a villainous toothy grin. His right eye twitched slightly and he gave off an extremely villainous aura around him. For all onlookers it was if they were in the presence of the literal devil.

"Not enough huh? Fine. You're gonna regret not passing out!" he growled as he slowly stomped over to Goku who was slowly starting to make his way to his feet. Bakugo's hands twitched with anticipation. Goku's tracksuit was singed and his entire gym shirt had been vaporised. He looked not only exhausted but also extremely in pain.

"Enough? Hah you've got to be kidding me. I took on Nomu and survived. If I can't take on an explosion that large then I'm not much of a fighter" said Goku calmly with a confident smirk. That just seemed to piss Bakugo off even more. He launched himself at Goku who dodged and prepared to power up to Kaioken. However, Bakugo didn't give him the chance and attacked him again and again. Goku's face twisted into one of frustration and anger. Speaking of anger, the anger from before was still very much present.

"He's getting angrier?" said Momo quietly.

"Which one?" laughed Kaminari before Jiro smacked him on the head.

"Goku obviously you idiot! I just hope Bakugo doesn't say anything that will make Goku snap" she prayed. Unfortunately considering the current situation this outcome looked unlikely. Goku had just dodged another attack from Bakugo and turned 180 degrees clockwise to dodge an explosion. He was about to move again before he noticed that Bakugo had stopped attacking.

"You're too weak to stand against me now. No point in attacking you is there? Kakarot" said Bakugo. That one word. That one name caused Goku to freeze in place. He stared down Bakugo in shock and anger.

"What did you say?" he said trembling with anger.

"Didn't you hear me the first time? What's the matter Kakarot? You deaf or something? What a joke" scoffed Bakugo without realising how dire the situation was. Goku's glare deepened and his rage boiled to new heights.

"WHERE DID YOU HEAR THAT NAME?!" he questioned with rage in his voice. Bakugo just grinned.

"Oh you know. Heard those extras that you call your friends say it. Figured it was a good prodding point" he admitted with evil intent.

"Why you little…" was all Goku could say before Bakugo held his finger to his mouth in a 'be quiet' action. The evil grin still remained.

"Now if I'm not mistaken I'm right in assuming that Kakarot is your given name correct?" he questioned. Goku remained still.

"What's it to you?" came Goku's question.

"It's just that if your mummy gave you that name then she must have been some stupid, weak, pathetic person. She may as well have died during birth than see the disappointment and weakling that you've become. I bet she's turning in her grave at that right now" was Bakugo's cruel reply.

"Considering how your entire family is dead I can say but one thing. If I was their son they wouldn't have died! They'd still be alive today. And they wouldn't have had to die knowing their son did nothing to help them. I bet they'd rather die than live knowing you're weak" continued Bakugo. That was it. The final straw. Goku's calm state literally snapped in half. His fists clenched and his head was lowered. His eyes had narrowed in anger. Bakugo stood still in confusion and also pride not realizing what was about to happen.

"I can't believe Bakugo just said that!" cried Jiro in anger. Her entire class was furious and ashamed of their classmate.

"Kacchan. How could you?" muttered Deku as he tried to rack his brain around what had just been said.

"What's the matter? Did I hurt your feelings?" mocked Bakugo. Goku grew angrier with each word.

"How dare you? You consider yourself a hero?!" snarled the furious teen. Tremors had begun to be felt by not just Bakugo, but everyone in the vicinity of the match. Present Mic, who had been silent a long time, was freaking out in the commentator's booth while Aizawa looked on in concern.

"Yeah I do. I'll be number one! I'm better than all you pathetic extras!" exclaimed Bakugo who couldn't sound more arrogant if he tried.

"Damn you. You heartless, ruthless, arrogant self-serving bastard!" growled Goku as the anger in his voice skyrocketed. His head lifted up, he snarled and then his head dropped back down again. He did this twice in a row. Yet what was more peculiar was what was happening to his hair. His messy yet spiky black hair was standing up by itself and turning an iconic golden. Class 1-A recognised this or kind of recognised it.

"That's familiar. It looks almost like what happened to him when we were at the battle simulation. That golden aura is even flashing on and off again" announced Kirishima quietly for only his class to hear. They all looked at him in shock and worry. They turned back to the match and saw the ground start to fracture. Suddenly there was an almighty boom as there were multiple lightning strikes around the city. The damage caused was great but not unmanageable to deal with while the match was going on.

"RRRRR. RRRRRRAAAAAAAGGGGGGGGHHHHHH!" screamed Goku as his pupils disappeared and he pulled his head back, his hair spiked up and the golden aura completely enveloped his body. The golden light that emanated from him blinded the entire stadium and went on to envelop the surrounding area around the stadium. When it began to die down all present saw it recede around where Goku was standing, completely enveloped in the gold aura with only his eyes truly visible. The aura receded into him and his body became clearer to see. His tracksuit bottoms were still ripped but besides the golden hue around him what caught the eyes of everyone present was Goku's now greenish-blue eyes and spiky golden-blond hair which was standing up. His body had slightly changed as well with his muscles now being more defined. Bakugo looked shocked and slightly terrified at the figure before him. The audience felt fear as well but also awe. They had just been witness to Goku achieve a powerful new form. Goku moved slightly to glare at Bakugo who stepped back in fear before clenching his fists and placing his right foot forward.

"You think changing your hair colour will save you?! You're wrong!" he screamed. Goku didn't react and just continued glaring at Bakugo who had placed his arms behind his back with his palms open.

"Time to die!" yelled Bakugo as he launched himself forwards and then into the air using his explosions. Using the force from his explosions he launched himself further into the air and forwards before using them to launch himself into a spin which turned into a giant corkscrew attack of explosions. The attack was heading straight for Goku who still hadn't moved an inch. Bakugo uncurled from his spin and threw his right arm forward at Goku with his hand open and a massive explosion brewing.

"HOWITZER IMPACT!" he screamed as the attack connected with Goku. The explosion ripped through the air and Jiro looked concerned for her friend. The smoke and dust that had been thrown into the air dissipated to reveal Bakugo in the air with his arm still out. He held a smug look on his face which turned into one of fear. His attack hadn't connected with Goku like everyone originally thought in the way everyone thought. Instead, everyone could see that Goku had his right hand out and had caught Bakugo's hand with the teen in question so caught up in beating Goku that he hadn't noticed. Goku was unscathed from the attack. Clenching down on his opponent's hand, Bakugo cried out in pain as his hand was being crushed from barely any effort from Goku. Goku then let go before performing a roundhouse kick to Bakugo's stomach sending him flying. Goku flew past Bakugo and grabbed the back of his head in a firm grasp. He began to squeeze again and uppercutted Bakugo slightly into the air before appearing above him, placing his right hand on Bakugo's face and slamming him into the ground. This formed a massive crater. Goku stood up straight and brought Bakugo up to eye level like the latter had done before. Bakugo looked on the verge of passing out but still showed fear and frustration in his face.

"Say my name" said Goku with little emotion besides a hint of anger. Bakugo struggled to form words and instead spat blood in Goku's face who remained unfazed.

"Go to hell" responded Bakugo. Goku's glare deepened.

"You first" he declared silently as he fired a massive ki blast from the hand holding Bakugo's head. The boy went flying out of bounds and into the wall of the stadium. He was unconscious and Goku had won the match.

"The winner is Son Goku!" announced Midnight but Goku wasn't done yet.

"RRAAAGGGHHH!" he growled loudly before locking his eyes onto Bakugo. He lost control of his temper and his pupils completely disappeared. No not disappeared. Literally shattered. He began to launch multiple powerful ki blasts at Bakugo and each one hit with the unconscious teen slamming into the ground and then bouncing back up again. The audience grew scared and Midnight ripped off part of her clothing as a pink mist circled around Goku's face. His onslaught continued much to the shock of Midnight.

"My quirk isn't working. How?" asked a shocked Midnight. A slab on concrete appeared in front of Goku and the boy stopped his offensive attack on Bakugo. He turned his attention to the UA staff attempting to stop him and launched himself at them. He knocked the hero Cementoss away with a simple backhand before performing a roundhouse kick on Midnight who had little time to react and was as a result sent flying. The audience had begun to panic.

"RRRAAAAAGGGGHHHH!" growled Goku in rage before he heard a crash behind him. He turned to see All Might in his muscular form crouched down.

"Stand down young Goku. The match is over. Don't make me hurt you" boomed the pro hero before launching himself at Goku who slightly dodged and threw a punch which connected with All Might's weak spot. The hero coughed up blood before clutching his only weakness. Deku's eyes opened in shock and fear.

"Ho..how? Aaack" sputtered All Might before barely blocking another punch from Goku. As the fight went on it became clear who had the high ground. Goku was pummelling All Might in pure rage. All he saw was red. What he didn't realise due to his blind rage was that All Might had been analysing his attacks. The pro hero uppercutted Goku, connecting his fist with his chest at such a force that Goku immediately depowered and was knocked unconscious.

"I'll admit young Goku you are very powerful in that form. However, to fully access that form's true power you must first get your emotions under control. In your rage your fighting style and cool-headedness behaviour vanished. That slip up gave me the opportunity to take you down" revealed All Might before turning to the audience.

"AS A RESULT OF WHAT HAS JUST TRANSPIRED THE SPORTS FESTIVAL HAS BEEN CANCELLED. WE APOLOGISE FOR ANY CONCERNS FOR SAFETY. PLEASE LEAVE QUICKLY AND EFFICIENTLY. THANK YOU FOR YOUR TIME!" boomed the number one hero as the entire stadium began to empty with all civilians leaving as fast as they could. Class 1-A were the last of the spectators to leave. As they did Jiro heard multiple people whispering amongst themselves.

"Did you see that?" asked a bystander to another.

"Yeah. That guy was a monster" was the answer.

"No not a monster. More like a devil" was the reply. Jiro was in the frame of mind that walking up to them and punching them seemed like a reasonable thing to do. As she made her move she felt a hand fall on her shoulder. She turned to see Kaminari shaking his head with a look of understanding plastered on his face.

"Can you tell me Goku's quirk again Jiro?" came the voice of Aizawa from behind the violet-haired girl. She turned around quickly and went to bow in respect before Aizawa shook his head. She proceeded to instead face her homeroom teacher.

"It's ki manipulation sir. Goku can use a type of energy called ki to fire energy blasts, power himself up and now fly. His main form of ki empowerment is Kaioken although that may change now due to him finding a new means of using his ki to grow stronger" she explained. Aizawa remained motionless and expressionless. This unnerved Goku's three main friends. Momo broke the silence.

"Why do you ask Mr Aizawa?' she asked with curiosity. Aizawa looked at the three before sighing.

"Because Yaoyorozu that form wasn't a part of his quirk" he admitted. The three tilted their heads in confusion. Noticing this Aizawa sighed once more.

"That form wasn't created at will. I doubt he even realises that he powered up. It only manifested once his rage exploded which means something else caused it" he explained.

"You mean Goku has another quirk?!" asked Kaminari in shock.

"Perhaps. Or I could be wrong and it could just be that his quirk evolved in a certain way. Who knows? I doubt he'll let anyone run any tests on him. Although we may have to show him the footage so he knows what he can work towards now" he responded calmly.

"People think he's a freak and a monster. Bakugo's the reason that Goku reacted that way! They should be calling Bakugo the monster!" cried Jiro in anguish. Although they hated to admit it Kaminari and Momo had to nod in agreement. Had Bakugo not made those comments about Goku's family the whole situation wouldn't have happened.

"People can form their own opinions about whoever they want and honestly I don't care. That kid's come too far and dealt with too much pain and loss to let a few comments get to him" said Aizawa with genuine compassion, shocking the three students standing before him.

"Although you three could do me a huge favour" he muttered.

"Anything" responded Jiro quickly. Momo and Kaminari agreed.

"Keep an eye on him. Make him feel wanted. Help him relax. Be his friends" commanded Aizawa with sincerity.

"Oh and most importantly don't let him anywhere near Bakugo. You got all that?" he asked.

"Yes sir!" cried all three students in unison. Aizawa smirked.

"Good. Now get home. I'll see you tomorrow in class. I've got an important announcement to make" he commanded and with that the three students went their separate ways. Aizawa suddenly got a buzzing in his pocket and using his free hand he took out his phone. His eyes widened at who was calling.

"What's up?" he asked. His face morphed into one of surprise.

"No way. You want to train him? You want to help him harness his power? Yes I know he's strong and prone to make rash decisions. The kid lacks common sense okay? Alright. Either two things will happen now. Either you'll be his only offer or he'll get others. Either way the choice is his. Okay I'll take this into consideration. Thank you. Oh and one last thing. When you take him under your wing do me a favour. Call him Goku and not Kakarot. That will raise flags that not even you can deal with. Got it? Good. Anything else I can help you with? Okay thanks for calling. Be in touch soon" was the conversation from Aizawa's side. Aizawa ended the call and placed his phone back in his pocket. He looked up to the sky and sighed.

"Son Goku. The kid who keeps pushing his limits just got an offer from one of the best martial arts teachers around. If he says yes to the offer then he gets a whole week to start the training to hone his new form. Why do I see this not ending well at all?"

Author's Note

That was a doozy huh? Yes i tried to find a way for the Super form to be accessed due to a particular person's actions and who better to be the cause than good ol' Katsuki Bakugo! So Goku can now turn Super. Now i know some of you may start trying to argue that Super Saiyan wouldn't necessarily be a part of Goku's quirk which is Ki Manipulation and I know this. I've thought it over and it will be revealed how this works. Won't say when it will be revealed though so you best stay tuned.

If you get the references congrats and if you can guess Goku's new teacher then also congrats!

Once again I hope you enjoy and are looking forward to the next couple of chapters! Don't forget to leave a review. Much appreciated.

So long!
