Chapter 16: Thunder Striking Twice

Izuku saw things slowing down in front of him. The only thing he can hear is the sound of his heart rate speeding up. He felt a jolt and heard the sound of striking thunder. Suddenly he found himself crouching by the girl who's leg is trapped under the debris. He looks up at the approaching giant and back at the girl thinking of what to do.

'Even if I get her free we'd be in the way of the giant bot still.'

Izuku thought to himself. He looks at the girl as she looks back at him with fear in her eyes. He takes a breath and places his hands on the concrete that's holding her down. Starting to lift up the slab he can hear the zero pointer get closer to them. He can also hear Jirou shouting at him to run. There isn't enough time to lift up the concrete and avoid the bot.

'Think Izuku, think!'

He lowers the concrete back down and the girl looks at him in shock. Izuku stands up straight looking at the villain bot for weak spots. He makes a fist and sticks out his pointer and middle fingers with both hands while getting into a balanced position. Moving his hands in circular motions he remembers what Iroh taught him long ago. Green and blue lightening started to form around his body with loud zaps. With a loud battle cry Izuku thrusts his fist forward with his fingers aiming at the giant's head.

There is a bright flash of lightning and another crack of thunder. The other teens who heard it are very confused while the ones who saw what Izuku did are flabbergasted. Smoke is coming from Izuku's fingers and he falls to his knees. The zero pointer stands still for a moment with a hole going through its head. Suddenly it starts to fall back and as it crashes to the ground a huge cloud of dust picks up. Suddenly an alarm goes off signaling the end of the exam.

"ALL RIGHT LISTENERS THE EXAM IS OVER! PLEASE MAKE YOUR WAY TOWARDS THE EXIT AND HELP THOSE WHO CAN'T MOVE ON THEIR OWN!"

Present Mic says as the dust starts to settle. Izuku looks back at the girl and lets out a sigh of relief. Now that he can get a better look at her he notices her big eyes. Her cheeks seem to have a permanent blush on them making her look shy. He takes a breath and starts to lift the concrete again. She manages to crawl out from the debri and checks on her leg.

"Thank you so much for helping me! I thou-"

Before she could finish her sentence Izuku falls to the ground unconscious. She lets out a surprised scream as other teens are gathering around them.

"Out of the way you youngins! Let an old lady do her job, sheesh!"

Pushing past the teens is a small elderly women dressed like a nurse. Some of them recognized her as Recovery Girl, the hero that can help heal injuries with a single kiss. She knelt down beside Izuku and took his pulse.

"He'll be fine. He has slight quirk exhaustion but he'll be good to go in a couple hours."

Medical bots came and carried Izuku and other injured students to the recovery room while she handed out gummy bears that helped with exhaustion. The girl who Izuku helped watched as he was carried away with a worried expression. Jirou seeing that Izuku is being carried away follows after.

-In The Watch Room-

Nezu sat in his chair with an impressed look on his face. The other teachers had looks of shock at how a new student took down the zero pointer. Even All Might is caught off guard by the display of power. Aizawa is the first person to come back to his senses.

"I can already tell that he's going go be a headache to deal with."

The man said, clearly annoyed. Nezu let out a chuckle as he continued to watch the screens. All Might kept his eyes on the screen that showed the med bots carrying Izuku away. His thoughts are clouded by the kid who risked his life to save another person for the sake of doing good other than making sure he has a good score. Aizawa lets out an annoyed sigh as he picks up the katana that has been put against the wall. Nezu and All Might watch as he leaves the room, confused as to why he has a katana in the first place.

-Back With Izuku-

Izuku stood in the void once again with a panicked expression. It felt as if his body was hit by lightning. He can feel the electricity running all throughout his body. He clenched his teeth not in pain, but in anticipation. He let out a breath with what seemed like steam coming out of his clenched mouth. Suddenly the void filled up with striking thunder as green and blue electricity sparked around his body.

While the lightning danced around his body Izuku noticed two people standing before him. The sparks died down and he fell fo his knees. Izuku looks up at the people standing in front of if him and notices their appearance. There is an elderly man and another man who appears to be in his prime years. Both of them wore similar uniforms with a haori that have triangles on it.

"This is the transparent world again isn't it?"

Izuku asked the two. The blonde man took a step forward and knelt down to meet the height of him. Izuku looks up to him with a confused look. Before he can say anything the man makes a fist and brings it down on Izuku's head.

"Hey, show some respect to gramps would you?!"

He shouted as the older man sighed with a sweat drop. The older man brings down his fist on the blonde man's head the same way but with enough forced to floor him. Izuku watches in slight fear and amusement.

"I'm sorry about this idiot. I'm guessing you met another one of us if you already know about the transparent world."

The older man said. Izuku nods and looks at the man on the ground. He slowly gets up while mumbling about the pain. The older man offers his hand and helps Izuku back to his feet.

"Why do I come here so often? How are you and the other slayers here?"

Before Izuku could ask more the man holds up his hand to silence him. He then looks at the younger man and nods at him. The blonde man nods back and from his back he picks up a sheathed Katana. The sheathe is white with the guard and handle being the same with bits of yellow. Izuku notices that his own katana is strapped to his hip.

"My name is Jigoro Kuwajima and this man here is Zenitsu Agatsuma. We are the users of the breathe of thunder."

-With Kyoka-

Kyoka followed the medical bots as they carried Izuku away. What she witnessed was pretty crazy for a school entrance exam. What made things crazier is that the boy that saved her seems to have two quirks. She saw him using fire to melt and destroy the villain bots at the beginning of the exam but when he shot lightning out of his fingers, it confused her. Before she could follow the bots into the building Recovery Girl stopped her.

"Sorry, but you'll have to join the others. Only the injured are going to the infirmary so I can help heal them."

The purple haired girl wanted to retort but saw Izuku shake a bit with green electricity sparking around him. She only nodded and watched the older woman examine Izuku. She said something to one of the med bots and they left her to her own thoughts. She felt a tap on her shoulder and turned around to see the brown haired girl that Izuku saved.

"Um, hi there. I was uh, wondering if you knew that green haired guy."

-Back In The Transparent World-

Izuku held the handle of his blade with both hands. His eyes are darting all around trying to find the man zooming around. There's something bothering him as he looks around for the blonde. He can clearly hear the sound of thunder striking every time Zenitsu changes direction but there is so sign of lightning anywhere. The only thing that Izuku sees is the blur of the yellow haori.

'What is this speed? Not even Rengoku is this fast! It feels like the air is buzzing around me.'

Suddenly the blonde man appeared in front of him with his blade held to his throat. Jigoro grinned proudly as he watched Zenitsu perform the technique flawlessly. Izuku couldn't believe that the man is that fast while being quirkless. All his life he has seen everyone over glorify people who have quirks and treat thoughs who are quirkless or who have weaker quirks awfully. He smiles brightly having a new respect for the "powerless" that are still skilled.

'Wow, even people who don't have quirks can get this strong?'

Izuku falls to his knees and bows his head. Both Jigoro and Zenitsu smile at him in respect. Jigoro kneels down in front of the boy and pats his head. Izuku knows that at his current level he wouldn't be strong enough to take down any big enemies. Even sparring with Rengoku still gets difficult when he stops holding back. He looks up at them with pleading eyes.

"Please teach me."

-Back In The Actual World-

Izuku's eyes snapped open as he sat up quickly. He looks around the unfamiliar room and notices Recovery Girl sitting at her desk looking over some papers. She notices him sit up and smiles warmly at him. He notices that he's in the infirmary and lets out an exhausted sigh. Then he realizes who's been watching over him.

"No way! You're Recovery Girl! I've read so many articles about how you've saved thousands of people!"

The elderly woman smiles in slight shock at hearing his praise. Not many people knew about her and only cared whether or not she can heal them. She walks over to him to check his condition.

"Thank you sonny, that means a lot. Now stay still while I examine you over. You fell unconscious after over using your quirk and straining yourself."

Izuku nods his head while listening. He looks to the side of the bed and notices his katana leaning against the bed. After Recovery Girl finishes the exam he picks up the blade. She notices and goes back to her desk. After a minute of filling out some paper work she looks back at him.

"I have some questions for you young man."

Izuku looks back at her with another nod. She looks over some papers with a look of interest. The looks makes Izuku nervous so he fidgets a bit.

"Your file here says that you were a late bloomer correct?"

He nods yes at the question wondering why that is important.

"Yes, my quirk manifested a year later than most kids."

She hums in thought while reading more of the file in her hands. Then it suddenly dawns on him what she's getting at.

"Your file also says that your quirk is a fire type correct?"

He nods again but tries to explain his situation. Recovery Girl just listens in interest and takes notes here and there during his explanation.

"When I was younger my mother and I thought that fire was all that I can produce. It was around middle school that I've noticed the electricity appearing. I later joined a dojo to learn how to control my fire but luckily the teacher who is there also taught me how to hone my electricity."

While he told his story Recovery Girl admitted that she is impressed by his show of skill. While his use of fire is acceptable, his lightning does need more work in control. The only noticable injury that Izuku had was his finger tips were slightly burnt.

"Now that's an interesting quirk. It's rare to see someone who has more than one ability. Duel quirks are also more dangerous and difficult to master so I hope you train hard sonny."

Izuku smiles at her and stands up with his katana in hand. The smile is bright and has the look of 'I can do it'. She smiles in return. He bows in front of her on respect.

"I will work my hardest to become a great hero like you. Thank you for treating me."

She bows her head slightly in return. She hands him a small bag of gummy bears and pats his head.

"I hope you do young man. I hear that everyone who saw you take down the zero pointed said you made thunder strike twice."

"huh?"

-Later At The Midoriya Apartment-

Izuku stood in his room looking at the long mirror on his door. He looked at himself with an impressed look. The exreme training really showing on his body. He has the build and muscle of a runner but is still able to pack a powerful blow. He looks at his hands and arms and sees the scars from his hard work. A knock on the door brings him back to reality and he jumps surprised.

"Izuku, how did the exams go?"

He heard his mother ask from the other side of the door. After quickly opening the door and letting Inko step into the room he sat on the bed. She did the same, her focus directed to her one and only son. This made Izuku smile brightly at his mother. He knew that she had some conflictions about him becoming a hero, but nevertheless still supported him.

"They were amazing! The tests were a bit harder than I thought but still manageable. The physical portion was insane though!"

Inko smiled proudly as she listened to her son explain what happened in the exam. She is so happy at how far her baby boy has come since he was younger. Back when he was a toddler she felt like she had failed him because of his quirklessness. She did everything in her power to make up for not being able to help him achieve his dreams. But listening to him talk with such enthusiasm now fills her heart with so much joy.

"-Then there was a giant villain bot that was as big as the buildings. I helped save another student by shooting lightning through its head! I passed out after that and woke up in the infirmary due to slight quirk exhaustion too. It was worth it too because I was able to meet recovery girl!"

His smile soon turns into panic as he realizes he didn't ask her for an autograph. His mother sees his face and knows exactly what he's thinking as she tries to hide an amused smile.

"AHHHH, I DIDN'T ASK HER FOR AN AUTOGRAPH!!!"

-Elsewhere-

Inside a dark warehouse stood three figures. One of them being a tall man in a suit with a horribly scarred face. The other two are Dr. Tsubasa and Tenko. The boy's body is noticably different from when they first abducted him. His build is muscular but also slim and agile looking, similar to Izuku's. Dr. Tsubasa stood next to Tenko with a crazy grin.

"I believe he is ready for the quirk master."

Tenko has a nervous look on his face as he tries to avoid looking at the taller man. He knows that this monster has the ability to take and give quirks through physical touch. During his training the crazy doctor always rambled about giving Tenko the perfect quirk suited for taking on heroes in battle. He did have to admit that he is curious to what quirk the overpowered man will give him. The tall man steps forward so that a flickering light above shines on his face showing the horrible scars and lack of eyes.

Tenko held in a gag as he looks at the man's face. The doctor always seemed excited to see the disfigured face which disgusted the light blue haired boy.

"Remeber what I told you doctor. This isn't a quirk. It's something more than that. Something that has been around longer than even you."

Tsubasa looks at the scarred face in disbelief. The doctor has been around for a long time and with the help if his quirk Life Force it allowed him to age far slower than others.

"What do you mean by that sir?"

All for One reached out with his left hand for both the doctor and Tenko to see. At first notning happened, but a moment later the skin on his hand began to move and shift around. The nails on his fingers turned black and grow to a point. Without a work he leans forward and stabs Tenko in the chest with his pointer finger. The doctor watches with wide eyes without a word. Tenko's blood curdling screams drown the warehouse as the boy's body began to change.

-Midoriya Apartment-

Izuku can be seen standing on the apartment roof again. This time he doesn't have his blades but instead is going through different fire bending forms while controlling his breathing. He thinks about the exams and how he was able to save that girl from being crushed by the zero pointer. With each kata being done, Izuku inhales and exhales in rhythm of each movement. No flames are being produced, just the motion of different forms.

The greenet noticed that controlling lightning through fire bending and using his natural electricity feels completely different from each other. Iroh taught him to seperate the positive and negative energy in his chi to create the cold blooded fire but he doesn't have to do that when making his own electricity. That doesn't mean both are easy to control once created. The energy that passes through his body feels like being struck by lightning but since he has a slight immunity to both fire and and electricity it just feels like being filled with some kind of energy.

Finishing the last form he places his hands together and lets out a breath with some smoke coming out of his mouth. For a moment he stands still. Lifting up his hand a small flame ignites just above his palm. He watches the flame dance. Closing his eyes he takes in a deep breath while the fire slowly turns blue and green.

I've been busy with stuffs so I apologize for taking month to update. It took me forever to finish this chapter but I enjoyed it. I hope that everyone is liking the fic so far. I also plan on adding other things from various anime and shows to make things more interesting. Hope that you are all doing well.
