Limits Revealed

This was it. The day he had been waiting for. The day he started UA High School to train to become a hero. Goku awoke early and went about his day as usual: a 20-minute jog, a hefty breakfast, cleaning up, changing, brushing teeth and finally walking out the front door for school. Today was different though as he was instead walking out the house with his brand-new UA school uniform. Goku tugged at the collar of his shirt with unease. He had never really liked school uniform and much preferred training attire but with his future as a hero on the line he had decided to suck it up and not complain. Besides he wanted to impress his teachers and peers.

Arriving at UA was the easy part for Goku. The hard part was finding his homeroom which was part of the Hero Course designation Class 1-A. After much searching and getting lost, one of the reasons he intended to arrive earlier than other students, he eventually spotted a familiar figure walk down one of the hallways and stand at a door. Using his quirk to sense their energy a goofy smile appeared on his face as he ran down the hall towards them.

"Jiro! It's me Goku! Man am I glad to see you made it into UA as well!" he shouted with clear joy in his voice. Jiro looked to her left and was greeted by a pair of arms wrapping around her in embrace and lifting her into the air before being spun around once and plopped back down to the ground. Jiro look bewildered and a little flustered before pushing her violet hair back off her face and smiling at her enthusiastic assailant.

"Hey Goku. Nice to see you here too. No surprise though after what I saw at the exam" she said while silently laughing at how naïve and innocent Goku appeared. Goku didn't appear to notice and continued smiling.

"Yeah I know right! It's crazy. All that work and I got in! Though I can't seem to find my homeroom heh" he chuckled awkwardly and Jiro smirked before turning back to the door and directing Goku's attention to what it read. When Goku saw it, his eyes went wide with shock, embarrassment and excitement as right in front of him in bright red was the insignia 1-A. He turned back to Jiro who nodded and proceeded to open the door.

What they saw was a handful of people, each with their own appearance and personalities established just by Goku looking at them. He always saw himself as a good judge of character and he could tell that he would get along with everyone in his class. His only concern was a blonde-haired boy with his feet on his desk. His eyes were red and he had a villainous aura surrounding him. This would have been easy to ignore had he decided to not have an arrogant and evil smirk on his face as he was being reprimanded by a tall, blue haired boy with glasses. The tall boy was shaking his hand up and down incredibly fast and Goku mentally admitted that not even he had a chance of telling how fast it was being done. Goku saw that Jiro had already claimed a desk as her own so he decided to as well. He noticed a seat at the front that hadn't been taken and decided he would perch there. As he placed his bag on the ground and sat down in his chair, he sensed two pure hearted energies at the door and looked over to see a boy with green curly hair and freckles blushing and talking to a girl of similar height with shoulder-length bobbed and slightly curled auburn coloured hair. The girl herself had a perpetual blush on her cheeks.

Before Goku even had time to introduce himself, a voice spoke up from behind the two latecomers.

"If you're going to just stand there then you may as well leave" came the solemn voice. Both the green haired boy and cheery girl turned around and looked down before screaming out in shock. Goku wanted to move to see what it was but after the previous comment decided it was best if he just waited. The rest of the conversation was blocked out by Goku as he started to daydream about being a hero.

"Alright class listen up. My name is Shota Aizawa but you'll just call me Mr Aizawa. I'm your homeroom teacher and I won't take any annoyances lightly. With that said get your gym clothes on and meet me outside in five minutes" the voice from before, now standing at the front of the class, bluntly stated. Goku snapped out of his daydreaming at the word 'gym' and as Aizawa finished speaking Goku jumped out of his chair and bolted for the changing room. The rest of his class looked shocked and confused but quickly followed after him. By the time they had arrived at the changing rooms, Goku was already leaving clad in his brand-new UA gym tracksuit.

"Aah. That's way better. Time for some training! This is gonna be fun! Woohoo!" Goku triumphantly yelled causing all classmates save for the blonde-haired boy and a boy with both white and red hair to look dumbfounded. Eventually everyone in 1-A arrived outside and were greeted by Goku and Aizawa who were waiting for them. Aizawa seemed slightly disturbed by Goku's enthusiastic attitude but what did he really care. The sooner this was over the sooner he could go back to sleep.

"Alright then. Apart from that one you took too long. Imagine if someone was in danger. You would have been too late to help. Regardless it's time you knew why you are out here. I don't care about the introductory talk. I'm holding a number of exercises. You can use your quirks in them. The goal is to get the best result in each of them. There will be a leaderboard at the end and we will see where you are placed so you can know your limits and how much you have to improve" he stated with a lack of enthusiasm. The class, besides Goku, looked relieved until a sinister smile appeared on their homeroom teacher's face.

"Did I forget to mention? Whoever scores last will be instantly expelled. Don't be that person" he evilly chuckled. The majority of the class went into panic mode with each of them arguing how that was unfair. The response was that life was unfair.

"Psst. Goku. Why aren't you nervous about all this?" Jiro whispered. Goku turned and gave a small grin.

"I've trained my whole life. Plus, if we can use our quirks then I can show all of you plus Mr Aizawa what I'm capable of. I'm sure we'll both do great!" he replied while holding his hand out for Jiro to high five. She rolled her eyes, smiled and high fived his hand. With that the exercises began.

The first couple of exercises were basic. Long jump, sit ups, press up etc. were all relatively simple for Goku who was expecting more exciting events. Eventually when he had to do 100m he felt his blood begin to flow faster. He readied up at the start line next to the green haired boy from before.

"Hey I just want to say go all out ok!" Goku cheerily said to his competitor who looked nervous and just simply nodded. As Aizawa prepared to yell 'Start' Goku decided to power his body up.

"KAIOKEN!" was yelled before he was enveloped in an aura of red.

"Start" came the holophrastic sentence from Aizawa. In a flash Goku pushed off the start line and was at the finish line almost instantly. He depowered and was really excited until he saw his competition just normally running. Aizawa read him his time but Goku was so busy thinking of why the green haired boy hasn't used his quirk that he failed to notice. Eventually the time came for the final exercise. A ball throwing challenge.

"Your goal is to throw the ball as far as you can. Bakugo. In junior high, what was your best result for the softball throw?" Aizawa asked the blonde-haired boy now identified as Bakugo. Bakugo gave zero effort and responded bluntly.

"Sixty-seven metres"

"Then, try doing it with your quirk" Aizawa suggested. Bakugo took the softball from Aizawa, walked up to his serving position and prepared himself. He pulled his right arm across his body and readied his throwing arm before launching the ball forward into the air with an explosion. The gust of wind caused Goku's hair to flow in the wind but he simply had a goofy smile plastered on his face. Bakugo arrogantly turned to Aizawa who held out the distance measuring tool to show 705.2m. The class was in shock.

One by one they took their go at throwing. Some did way better than others. The cheery girl from earlier got infinity as her quirk appeared to have some control over gravity. Eventually it was Goku's turn. Taking the ball Goku couldn't help but get giddy at the prosper of finally showing off his full power.

"Body don't give out now. I've only got to do this once" he quietly told himself. He looked at the softball in his hand before getting into a throwing stance. When he was ready, he closed his eyes and prepared himself for the next part.

"KAIOKEN TIMES FOUR!" he yelled at the top of his lungs before the red aura from before appeared albeit this time it was more ferocious and rose higher into the air. Using all his power, Goku launched the ball into the air with a force so great many of Class 1-A fell either onto the floor or stepped back to cover the faces. As the dust cleared, they could see the red aura fade and Goku standing there with a visible look of pain on his face. Aizawa was in shock however. He held the distance measuring tool up to Goku and the entire class and their eyes, except Bakugo's whose narrowed in anger, opened wide in disbelief. The reading for Goku's throw was an incredible 897.5m. The highest result under the gravity girl's. What shocked them even more was Goku's goofy laugh and smile that followed.

The final thrower was the green haired boy. He looked nervous but finally threw the ball only for it to go…46 metres. He looked confused as did 1-A until they noticed Aizawa's hair had risen into the air and his scarf was levitating around his upper body. His eyes glowed a piercing red.

"I erased your quirk. From what I can tell, you can't control your quirk, can you? Do you intend to become incapacitated again so that you can be saved?" Aizawa menacingly berated.

"That's not my intention!" yelled the green haired boy before the scarf wrapped him up and drew him into Aizawa. There was clear fear in his eyes and Goku's brow furrowed as he realised what was going on.

"That's Eraserhead. Got to be" he said loud enough for those in the imminent vicinity to hear.

"What? No way. The underground hero who can erase quirks just by looking at someone?" gulped a blonde-haired boy with a black lightning bolt in his hair. Goku nodded and the class slowly turned to face Aizawa with fear in their hearts.

"Though in fairness from what he's saying it makes sense that that guy didn't go all out. His quirk must break his body. Which means he must be crazy strong!" Goku excitedly said. Jiro just facepalmed.

"Goku. Never change" she chuckled. The class, minus two, nervously chuckled as well. They all looked back to see the green haired boy take back up his position at the pitching post before launching the softball into the air. The distance measuring tool pinged up and Goku managed a peak. It read 705.3m. Goku, along with his classmates, was in awe. Goku was actually more excited to spar with this guy. One person on the other hand wasn't too please.

"DAMN DEKU! YOU'VE BEEN HOLDING OUT ON ME! MAKE A FOOL OUT OF ME, I'LL KILL YOuurrrk" yelled Bakugo. Aizawa was holding him back with his scarf and was erasing his quirk.

"Bakugo. It would be wise not to make me angry. Get back to the rest of the class. Now" Aizawa threatened as he pulled his scarf back and Bakugo tumbled backwards onto the ground. He stood up, growled and walked off but not before glaring at the green haired boy now known to Goku as Deku.

The leaderboard lit up with the results and Goku found himself in the top three. Nothing new for him really. It was last place that concerned him. It didn't take him long to figure out who it was. Deku was visibly shaking and appeared on the verge of tears. His dream had been crushed.

"By the way I was lying about the expulsion" Aizawa piped up. The class' faces looked surprised yet slightly horrified at the same time. Well everyone but Goku, Bakugo, the half n half boy and a rather attractive girl with dark hair and a questionable chest size that was.

"It was a rational deception to draw out the upper limits of your quirks" Aizawa bluntly said.

"WHAT?!" yelled the majority of the class in response.

"Of course, it was a lie. It should've been obvious if you just thought it through" the dark-haired attractive girl said. The class looked at her with an expression of 'Wasn't that easy to tell'.

"That's today finished. Have the rest of the day off. I expect to see you tomorrow on time please" Aizawa said while shooting a glance at Deku and gravity girl. With that he walked off and the school day for 1-A came to close. Even though it hadn't really begun yet.

Goku walked with Jiro to the gate as they discussed their first day at UA. Goku made clear his desire to improve his Kaioken technique while Jiro wished to develop her abilities as well.

"Yo Jiro! Kakarot! Wait up!" came a voice from behind them. Jiro turned around to greet the boy with the lightning streak in his hair from earlier as well as the attractive dark-haired girl as well. Goku however turned around with a glare before picking the boy up by his collar and threatening him.

"What did you call me?!" he growled. The boy had gone into panic mode and was sputtering over his words.

"Um Kakarot. Why are you threatening Kaminari?" questioned the dark-haired girl. Goku's sights immediately set on her and he dropped the boy known as Kaminari. He walked over to the girl before slamming her against the wall by the gate of UA.

"Where'd you hear that name?!" he violently asked as the girl stayed defiant but showed visible trembling.

"On the leader board it said Son Goku slash Kakarot. We thought Kakarot was just a nickname of sorts. Like carrot due to how spiky your hair is" she explained. Goku started to calm down and backed away from the wall allowing her to go free. She moved to Jiro's side as she helped Kaminari onto his feet.

"Sorry about that Yaomomo. He's never been like this before" Jiro explained.

"Let me guess. 'Yaomomo' is a nickname formed out of your first name and your surname. Isn't it Momo?" Goku growled with the trio in front of him looking more nervous by the second. Goku breathed in heavily once and then out again before looking up with a sad expression.

"I'm sorry for how I reacted just then. Please call me Goku. The name 'Kakarot' is reserved for only two people. People who are long gone now" he sadly said. Momo and Kaminari felt guilty. Momo placed her hand on Goku's right arm and Kaminari placed his hand on Goku's left shoulder.

"No, we're sorry. We should've asked first if we could call you that. We won't now" came Momo's response.

"Yeah sorry bro. Won't happen again. I promise. You okay Goku?" Kaminari asked. Goku looked at both with grateful eyes and lifted his head to show his signature grin.

"Yeah! Apology accepted! Now let's train to be heroes and fight strong opponents" he happily shouted with Momo and Kaminari agreeing. Jiro just smiled and closed her eyes.

"Seriously Goku. Never change who you are"
