I was thinking about doing a Boku no Hero Academia crossover with A Certain Scientific Railgun and decided to make this story. Hope you enjoy it!

Izuku kicked his legs as green electricity sparked around his whole body. He and his mother were currently with the scientist that will tell him about what his Quirk is. Unlike Kacchan who got his at the age of 4 like everybody else Izuku's had awakened at the age of 5, a year after Quirks manifest in children. He was teased at school mercilessly for not having a Quirk and was called Quirkless by the other kids, including his former best friend Kacchan but that all changed on his 5th birthday. He woke up and saw the stuff in his room was moved closer to him and his fingers sparked with green electricity, also the papers in his room moved around too but he didn't know why. He busted out of his room and showed his mom who immediately took him back to the Quirk Scientist and proceeded to yell at him for lying about him not having a Quirk. The poor man was shaking and decided to test Izuku again, so here they are now, just waiting for the results.

"Incredible..." the man breathed out.

Izuku stopped kicking his legs when the scientist said that. What was his Quirk that made the scientist say "Incredible?" It must be good, hopefully.

"What's wrong?" Inko asked.

He turned to them with a cough, "Forgive me, but instead of your son having a Quirk...it's something else."

"What do you mean? Is it dangerous?" She asked franctically.

"No, I assure you that what your son has is not dangerous, in fact its incredible." He promised her.

"What is it?"

"Are you familiar with the term, "Esper?" Midoriya-san?" He asked.

"Esper? Are you saying that my son is-!"

"Indeed I am," he confirmed, "Your son is the very first Esper user to walk amongst Quirk users."

Inko covered her mouth with both hands. Her son was an Esper! Just like...

"I'm sorry to ask this, but you does your family have a history of Esper users?" He asked suddenly.

"Y-Yes, my grandmother was Esper and my mother is one, too," Inko confirmed, "I remember a long time ago my mother told me that the Midoriya's come from a long line of Esper users, but my generation was skipped."

"I see," he wrote that information down, "And does it have a history of manifesting late or early?"

She thought about it, "The Midoriya family line has always been girls and their powers came at the age of 4, the same time as Quirks do. Izuku is the very first boy of our line."

Izuku didn't understand what his mom was talking about but it had to be important because they got so serious all of a sudden.

The science man did that thinking pose like the people on the detective show would do sometimes.

"Here's my theory on that, since he's the first born male of the Midoriya line that means his Esper abilities are far stronger." He theorized.

"You really think that?" Inko questioned.

He turned went over to the board and wrote something down, "I do actually. See, Esper has a different meaning than Quirk. Esper translates to "Ability User," while Quirk translates to "Individuality." Since Espers are believed to be a myth people will believe that your son's Quirks are a form of Mutation since he doesn't have a combination of you and your husband's Quirks."

She breathed a sigh of relief, "That's good."

"I agree, in my professional opinion its best that people believe your son has a Dual Quirk instead of being an Esper." The man told her seriously.

"Dual Quirks are a combination of two separate ones, right?" She asked just to be sure.

"Correct, now as for what your son's Esper abilities are, which I will classify as Dual Quirks for his own protection are called, "Electrokenesis and Vector Manioulation." He wrote down.

"Electrokenesis and Vector Manioulation?"

He put his notepad down and brought a piece of paper closer to Izuku and watched as it stuck to him, making him giggle.

"Your son has the power to generate and manipulate electricity," he explained, "Not only that, but your son might also be able to sense all phenomenon related to his power. He also has his own electric and magnetic field, as well as processing electromagnetic information either subconsciously or unconsciously."

Inko gave him a confused look so elaborated, "In other words he's a powerful lightning user."

She nodded, "And the other one?"

"Ah, now the other one took me by surprise," he admitted, "Now onto Vector Manipulation. This ability has similar properties to Particle accelerators that use electromagnetic fields to propel charged particles to nearly light speed. In my opinion its more similar to Synchrotron, which allows the manipulation of acceleration quantum particles. I believe that your son having this ability might allow scientists to get close in understanding the truth of the universe and the laws that govern it."

Inko unconsciously held her son, "Are you saying they might try to experiment on my son?"

"That's a definite possibility, which is why its best no one knows about the true extent of it." He said honestly.

"Thank you." She thanked the man.

"You're welcome," he said, "Now his Vector Manipulation ability is based on Vector Transformation, that allows him to control vectors of magnitude and direction. This also allows him to influence objects that have vectors such as, bullets, heat, and electricity. He can also use it offensively and defensively."

While Inko was proud that her son turned out to be an Esper, she was worried he might not be able to control his two abilities properly. To prove her point, her son was still letting out little sparks of electricity but it didn't appear to bothering him all that much.

"Can I..." Izuku hesitated a little as he spoke, "Can I still be a hero?"

Her heart clenched at his hesitation and frowned at herself for giving up on her son so quickly, instead of supporting him.

The scientist smiled at the boy with hopeful eyes, "Yes, you can become a hero."

Izuku beamed at him before turning to his mom, "Did you hear that, mom?! I can be a hero!"

She smiled, "I heard sweetie. Since you're on holiday why don't we go and visit grandma? She's been asking to see you."

"Really?! We can go see grandma?!" He exclaimed with excitement.

"Yes, we can!"

"Yay!" He jumped off the stool, going over to the door.

Inko stood up and bowed to the man, "Thank you for telling me everything I needed to know and for keeping it a secret."

"You're very welcome, Midoriya-san." He smiled at the woman.

The two members of the Midoriya family left with smiles on their faces. One, knowing that he can become a hero after all, and the other knowing her mother would be able to help Izuku in controlling his Esper abilities.

Izuku was very happy. He now had a Quirk, and not just one, but two Quirks. He could finally become what he always wanted, a hero! Now he was going to tell his grandmother the good news! He couldn't wait to see the look on her face when he tells her.

"We're here, Izuku." He heard his mother say.

Looking out the window he smiled widely when he recognized the long road that would take them to his grandmother's house. Unable to contain his excitement he grabbed his mothers hand and practically dragged her off the bus station.

"We're here, mom! We're really here!" Izuku letting out tiny sparks of electricity.

Inko smiled, noticing the brightness her son always expressed was back and wanted it to stay. The reason it was lost in the first place was because her son was being bullied at school for not having a Quirk, well in a sense he doesn't but that's no excuse to bully someone just because they're different. She knew enough about how those who don't have Quirks are treated poorly, and some even resort to suicide because they're unable to handle such prejudice. There was no way in hell she was going to let her son go through that, not anymore. Things will be different this time, this time she'll be supportive like she should have from the very beginning.

Location-Midoriya Family House

Inko wasn't surprised her mother was already outside waiting for them with a smile. Her mother's Esper ability was Precognition, the ability of Future Sight, so even if Inko called to let her know she still would've guessed they were coming.

"Baa-chan!" Izuku ran towards the woman, embracing her with a happy smile which she returned.

"Its so good to see you, Izu-chan. How are you doing?" She asked, giving him a warm smile.

He gave her and excited grin, "Guess what, baa-chan? I went to the doctor today and he said I can be a hero!"

"I see, that's wonderful news." She said, rubbing his head gently making him giggle.

Inko then approached, "Mother..."

"I know. How long is he off school for?" She asked.

"Two weeks," Inko told her, "The school decided to give the students a two week holiday, and I'm glad they did."

Inko's mother's eyes grew cold, "Ah, as am I."

Izuku tilted his head slightly at his grandmother's sudden angry expression but didn't get the chance to ask about it as the door behind them slid opened revealing an elderly man with strong features.

"Ah, I thought I heard the voice of my favorite grandson." He said.

Inko sighed, "Father, he's your only grandson."

"That's why he's my favorite." He stated.

"Jii-chan!" Izuku hugged the stern man who huffed in amusement and hugged him back.

"Izuku, why don't we go in the backyard and let these two talk for a bit?" He suggested.

"Okay!" Izuku nodded as the two of them walked inside the house, leaving the two women alone to talk.

Inko adressed her mother while her son and father did whatever they wanted, "He's not a Quirk user."

"But he is an Esper." Her mother stated. Inko's mother, Midoriya Sara was an Esper user along with the other women of their family line. Sara's Esper ability Precognition was highly sought after back in the day when Heroes were just starting to be recognized and depended on. She worked with both the Police Force and Heroes to help predict events that would soon happen, and every time she was right. When she got married however she decided that was the time to retire, so without a word to those of the Police Force and Heroes she worked along side with, she disappeared allowed her whereabouts to remain unknown. Those with with Quirks that could see into the future where highly sought after, just like those with Healing Quirks. She will not let her ability be used by anyone and her husband agreed with her. Her husband, Midoriya Hideshi's Quirk ability is known as "Aero" a Quirk that allows him to manipulate wind and its very powerful. The two of them were made for each other.

"Yes, I can't give him the training she needs, that's why I brought him here." Inko told her.

Sara gave her daughter an understanding smile, "I'll train my grandson to control his powerful abilities, and Inko?"

"Yes?" A soft hand touched her cheek and a kind motherly smile was given.

"You are a great mother," Sara emphasized, "Stop doubting yourself. I didn't raise you to have doubts about your abilities as a parent."

Inko sniffled before hugging her mother, crying on her shoulder and made a promise to never give up on her son, ever again.

Izuku was sitting lotus style just as his grandfather asked him too. His eyes were closed and he was trying to visualize the electricity flowing inside and outside of his body. Hence what he was doing now, his grandfather told him that this is very important and that he cannot be impatient. He was starting to feel something course throughout his whole body and slowly but surely felt a spark build up in his hands, curious he opened his eyes and gushed seeing small green electric balls in the palm of his hands. In his excitement he turned to his grandfather, "Jii-chan, look! I did it!"

Hideshi smiled, "That you have. Keep concentrating on it, though."

"Mm!" Izuku closed his eyes again and concentrated.

Hideshi smiled as he heard footsteps, "All done with your talk?"

"As a matter of fact we are," Sara said, sitting down next to him in the meditation room while Inko sat down on his other side, "How's our grandson doing?"

"I'm happy to report he'd doing well so far," he reported, "What was his other ability?"

"Um, the man said it was called "Vector." Inko said.

"Vector Manipulation, a very powerful ability if used properly. But since this is our grandson I'm talking about I have no doubt he will be able to control it." Hideshi said confidently.

"Funny, I was going to say the same thing." Sara smiled.

"Is it that dangerous?" Inko questioned.

"In the wrong hands, or if the individual is unable to control it properly." Sara explained, "I was told that the ability existed but wasn't quite sure if I'd get the chance to see it."

Inko sighed, "Its a good thing I brought him here after all."

"I have fond memories of when you were his age," Hideshi smiled nostalgically, "Always moving things around with your Quirk, it was very cute of you."

"Father!" Inko blushed.

Sara giggled at their antics, "Baa-chan, baa-chan!" She looked over and saw Izuku approach her with his hands generating green electric balls, "I made them bigger!"

"So I see, are you ready to train alot while you're here Izuku?" Sara asked.

"Mm! I'll train real hard and become a strong her like Baa-chan!" Izuku smiled.

Sara gave him a smile that was all knowing, "I know you will."

Two Weeks Later

Izuku spent the whole time at his grandmother's place training. He'd shown vast improvement so quickly, proving he was indeed of Midoriya blood. Their family line held not only strong abilities, but intelligence as well, which will serve Izuku well with his Vector ability. The boy was very smart in fact proving their point that even at 5 years old Izuku was special. However, as special he may be Sara made sure to drill it in him that no matter how powerful and special a person might be there always be someone better. She also told him bluntly that she didn't want him hanging around Bakugo Katsuki anymore, either. After Izuku told her that he was bullied for being Quirkless and who the instigator was she told him that he was no longer a 'friend,' but a bully. Izuku was about to protest before he stopped as his grandmother was always right, that and both his mother and grandfather agreed with her. Izuku was sad that he was losing his friend but his grandmother told him that he was about to make a new one very soon. Izuku was excited and asked her when he would meet his new friend.

Sure enough on that Friday, Izuku would meet his 'new friend' and create a stronger bond.

Izuku was happy to spend the last day at his grandmother's to go somewhere with them. They were currently in Mie Prefecture, which is part of the Kansai region on Honshu Island. He had never been here before and was bouncing on his feet as he walked around with his mother and grandparents, eyeing the many buildings and people.

"Enjoying yourself?" Sara asked, smiling down at her grandson.

"Yes!" Izuku grinned.

Sara chuckled, "Are you hungry? There's a mochi shop right over there."

Inko smiled, "Its been so long since I had mochi."

"That it has," Hideshi agreed, "You would eat the stuff whenever you could."

"Father!"

Sara and Izuku walked inside the mochi shop, as the father and daughter continued to tease each other. Izuku saw the mountain of mochi that were on display with wide eyes of astonishment.

'So many...' he stared into the glass window, his hands touching the glass. Another set of hands came up next to his making him turn to his left. Right next to him was a girl who looked to be about his age with fair skin, big round brown eyes, and shoulder-length brown hair which sports two long locks beside her face and a short bob at the back. She also has micro-bangs which sweep to her left. She was wearing a green shirt with long sleeves, a pink skirt, and brown shoes. Both children stared at each other before smiling with small blushes on their cheeks.

"Hi!" She greeted.

"Hello!" Izuku greeted back.

"I'm Ochako Uraraka, nice to meet you!" Ochako introduced.

"I'm Midoriya Izuku, and I like your shirt!" Izuku complimented.

"Thanks, I like yours, too!" Ochako smiled.

"Thank you!"

"Do you like mochi, Izuku-kun?" Ochako asked.

Izuku blushed, "I-Izuku-kun?"

Ochako panicked a little, "I'm sorry, was that bad?"

"N-No!" He shook his head, "Its just that...no ones ever called me by my first name before. You're the first."

"O-Oh, um, can I still call you Izuku-kun...?" Ochako asked, fidgeting in place.

"S-Sure! And can I call you O-Ochako?" He asked.

"Yeah!"

Izuku's smiled brightened up even more. Maybe this was the person his grandmother was talking about. The person who will become his new friend!

Speaking of said grandmother, she along with Inko, Hideshi, and Ochako's parents were watching Izuku and Ochako's interaction with a smile. Sara's prediction was correct when she said Izuku will have a new friend soon, and this girl was who she was talking about.

"Looks like they hit it off, just as I predicted." She muttered with a smile.

"Eh?" Ochako's mother said.

"Oh nothing dear, just an old woman having one of her private thoughts." Sara giggled mischievously.

Hideshi, who heard what his wife said rolled his eyes. His wife may give prediction but she was just as predictable herself.

The five adults talked while Izuku and Ochako talked to each other about many things they liked, from heroes, to food, and anything else.

"My Quirk is Zero Gravity." Ochako smiled.

"Zero Gravity?"

Ochako decided to demonstrate by touching a chair, allowing it to float, "The small pads on the tip of my fingers let anything I touch float just like this. I can lift heavy things too and it doesn't even bother me because it doesn't have any gravity."

"Wow! That's amazing Ochako!" He complimented, "I bet you can save a lot of people with your Quirk!"

She blushed, "Thanks, oh, by the way what's you're Quirk?"

He showed her two fingers, "I have two."

"Two?" She didn't understand at first but then got it, "You have two Quirks?!"

"Yep. Electrokenesis and Vector Ma-Ma-"

"Vector Manipulation, honey." Inko helped him.

"Right, Manipulation! Vector Manipulation!" Izuku grinned.

"Wow...you have two Quirks..." Ochako looked at him in awe.

He gave her an embarrassed smile, "Thank you, but I'm still practicing with them," pointing his finger at her nose he gave it a light shock that made her nose twitch, "See? I can send out small shocks like this, but Jii-chan says I still have to practice with it."

"Oh, what about the Vector one?" She asked.

Izuku thought about it before answering, "It lets me control Vector's. That's what Baa-chan told me."

"That's amazing, Izuku-kun! You'll be the strongest hero ever!" Ochako praised.

"So will you!" He told her.

"Me?"

"Yeah! I like my Quirks, but yours still sounds cool!" He told her honestly.

Ochako did something he wasn't expecting. She gave him a hug that made him freeze in place but he soon hugged her back, still confused by the sudden move.

"Thank you for saying that to me." He heard her mumble near his ear.

He smiled, "You're welcome."

She broke the hug and held his hands, "Let's be friends! That is...if you want to..."

He squeezed her hands with eagerness, "I want to! I want to be Ochako's friend!"

She grinned happily before sticking her pinky finger out, "Then let's make a promise to each other! That we'll be heroes!"

He grinned back, "Mm! But, we should be hero partners!"

"Yeah!"

The promise was sealed with a pinky promise. A bond has forged between two children who will soon carve a path together.

When it was time to go, both children were understandably upset but knew this wouldn't be the last time they see each other. Inko and Ochako's parents exchanged numbers so their children could talk to each other much to their liking.

Izuku was holding Sara's hand as she walked them to the bust stop. The smile on his face was so big that he couldn't help himself. He made a new friend and she was really pretty, too.

"Baa-chan?"

"Hm?"

Izuku looked down as he spoke, "Ochako...I thought she looked really pretty."

Sara giggled, "Is that so? Make sure you tell her that next time. And who knows? She might think you look pretty handsome."

"Is handsome a good thing?" Izuku asked, tilting his head slightly.

"Trust me, its very good," Sara assured him, "You two have become tied together, and the bond between you two will continue to grow," she stopped suddenly, crouching down before her grandson, "Listen to me, Izuku. You must continue to train in order to control your abilities. That means you must not hesitate, no matter what anyone tells you, no matter how hard they try to tear you down, no matter what cruel things are said to you. You...can overcome any obstacle, do you understand?"

Izuku was taken by his grandmother's serious eyes and understood what she was trying to say to him. His once friend Kacchan who he will now start to call Bakugo called him Deku and Quirkless all the time, making Izuku hesitate to speak up to him or fight back.

But no more.

"Then let's make a promise to each other! That we'll be heroes together!"

He made a promise with Ochako, and promised her they would become partners. Partners look out for each other and always have each other's back no matter what!

Giving his grandmother a determined look he answered, "I understand, baa-chan! I'll...I'll become strong! I'll become a strong hero just like you!"

Sara smiled as she hugged her grandson, "I know you will. I thought so from the moment you were born, that you will become a great hero."

With those parting words she saw them off, her smile never leaving her face, "The new generation will finish what we started. May you children forever keep your hopes and dreams alive in this new era."

For this nightmare finally ends...with all of you.

School was back and the children were currently playing outside as it was now recess time. Izuku was outside with the other children, but he didn't play with them as the other kids didn't want to play with someone who was "Quirkless." Normally that would bother him, but after spending time and talking with his grandparents he refused to let their taunts bother him anymore. Last night he looked up ways to have a personality opposite from his own. He looked up in the dictionary what word describes what he's looking for and eventually found it.

Apathy

According to the words that were under the word Apathy, it means to have a not caring attitude and without interest. He sat down on his bed in a lotus position, thinking about all of the abuse Bakugo and his friend put him through, along with his classmates who ignored him like he didn't exist. It really hurt. Then he thought about Ochako and her smiling face that washed away all of those negative feelings. He'd already decided. Just like his baa-chan said, no matter what they say he couldn't hesitate anymore, so he won't.

He heard what sounded like a 'meow' coming from on top of the tree he was leaning against. Getting up from the tree he looked up and did indeed see a small kitten that was crouched down on one of the tree branches, trembling in fright.

'Oh, no!' He felt sorry for the poor thing and tried to figure out how to get it down. His Electrokinesis? No, that would only hurt it. Vector Manipulation, maybe? Well, he still doesn't know how it works and now would be the right time to use it as a form of practice.

"Hey, Bakugo, what's Deku doing over there?" One of the kids asked Bakugo who currently had the ball in his hand. They were currently playing dodgeball and Bakugo's team was winning of course because they had Bakugo on their team. The explosive user turned to see what his lackey was talking about and saw Deku staring up at a tree like an idiot.

"Oi Deku, why are you out here with us that have 'Quirks?' Get lost!" Bakugo yelled.

Bakugo along with everyone else were expecting a reaction but Izuku wasn't paying them any mind as he was still worried about the cat.

"He's ignoring you."

"Is he crazy?"

Bakugo didn't appreciate being ignored by some Quirkless loser, "Don't ignore me, loser!" He threw the dodgeball he was holding at Izuku, expecting it to hit him only for it to explode caused by green electricity.

It was silent on the playground. None of the other kids were expecting 'Deku' to have a Quirk since he was Quirkless. Or he was supposed to be at least, but then what was that?

Izuku himself still hadn't notice, trying to decided whether to use his Electrokenesis or Vector Manipulation.

"What...?"

"I thought he was Quirkless!"

Bakugo stared in disbelief as he saw what remained of the dodgeball, which was nothing but ash. Deku had a Quirk? This whole time he had a Quirk?! So he lied about not having one this whole time?! Was he making fun of him?! He was seething as his hands glowed, "DEKU!" He charged at the boy who still had his back to him and everyone else. As Bakugo's fist made contact with Izuku's back, he was sent flying backwards by some invisible shield. He landed on the ground on his back, propping himself up on his elbows as he tried to process what just happened. The other children were confused too, Izuku just used lightning, so what was that?

"Wait, what was that?"

"Was that...another Quirk?"

"No way!"

"But we just saw it! He has to have two Quirks!"

"I don't believe it!"

Izuku, who was still oblivious to his surroundings decided to use his Vector ability to help get the kitten down. Taking a deep breath, he concentrated the air around him as he created two high powered tornadoes behind him that allowed him to levitate and reach the tree branch. Sitting on the branch, he reached his hand out towards the frightened kitten, "Its okay." He said gently, waiting patiently for the kitten to come over to him. The little guy went over to him slowly before sniffing Izuku's fingers and licking it, proving he trusted the child. With a smile Izuku grabbed the kitten gently before using his Vector ability to get him back down from the tree branch, landing safely on the ground.

"You got separated from your mama, right? Let's go look for her together!" Izuku said with a smile, giggling when the kitten licked his nose. As he walked away from the playground, he was still unaware of the faces of the other children who'd seen what he'd just did, including Bakugo.

Looks like Izuku wasn't so Quirkless after all.

As for Izuku himself, he couldn't wait to tell Ochako the good news about him getting a kitten down from a tree. He couldn't wait to tell her.

As soon as school let out, Izuku wasted no time in packing his things and running out the door. He spotted his mom, running up to her with a beaming smile, "Mom, guess what!"

"What?" Inko questioned, amused by her son's excited tone.

Izuku looked around before gesturing for his mom to bend down so he could tell her something. She humored him and crouched down to his eyes level, "I used my Vector Quirk to get kitten down from a tree." He whispered.

Inko wanted to scold him, but didn't since her son used it to save a helpless little kitten. The smile on his face was just too pure and honest to scold. Hand in hand, the two members of the Midoriya family walked home and Inko noticed the children were pointing at her son and whispering things but she didn't want to hear what they were saying about her son.

She no longer cared.

When they got home, Izuku immediately went towards the phone and dialed the number Ochako's parents gave to his mother and spoke to his friend. He told her how he saved a helpless kitten from a tree and felt warm when his friend called him a 'hero' for it. After talking on the phone for what felt like an hour the two children hung up and got ready for dinner.

As Izuku lay in his bed with a small smile on his face, he did wonder why his classmates and Kacchan were staring at him the way they did. Oh, well, it probably wasn't all that important anyway.

Except...his classmates made it important.
