Alright, let's do this one last time.
My name is Izuku Midoriya.
I live in a world where eighty percent of the population are born with superpowers, called Quirks.
Unfortunately, I was one of the lucky twenty percent born Quirkless.
I always wanted nothing more than to become a hero, which is something many people with incredible abilities choose to be. Even when I found out I would never develop a Quirk of my own.
It never stopped me from studying heroes and their abilities. And no other hero was as amazing to me as All Might. He had incredible strength and speed, and always saved everyone.
Well, one day I got to meet him! He saved my life from a criminal's ambush and I got to talk to him. At first, he didn't think I was worth it, but then I proved him wrong when I risked my life to save my bully from the same criminal (long story).
That evening, as the sun was setting, he spoke to me and told me that not only am I worthy to be a hero, but to inherit his power! Whatever that meant...
Months later, after intensive training with All Might, and completely clearing an entire beach of heavy trash, I was ready to apply to the school of heroes, UA High!
But first, All Might stood in front of me at the beach I just finished cleaning.
He smiled and pulled open his coat, revealing he was wearing his tight costume on underneath.
I looked at him puzzled then looked down as he pulled something right off of the suit and held it out.
"Here! Let this touch your skin. The only way you'll receive my power is if it bonds with your body!" He explained.
I stammered and hesitantly grabbed the strand. It felt gooey and almost felt like it was wiggling in my fingers. I shuddered. "Wh-What is this thing?..."
"The torch I pass on to you! It'll form into a suit for you that grants you abilities like mine!" He said. "Now do it! The entrance exam to UA starts in a few hours!"
"AHH right!" I shouted and slammed the goopy strand on my arm.
It felt very strange on my skin. And in no time, it sank into my arm like a heavy lotion and I could feel it move around...then it disappeared.
"Th-That's weird..." I gulped. "There won't be any side effects, will there?"
"Well let's see... If you're not the right kind of host, it might not bond well and...might try to eat you inside out." All Might said quickly.
"WHAT?!" I yelped.
"NO TIME TO EXPLAIN! GO!" He boomed and shoved me off.
~~~~~~~
Ok, I have no idea how to control this Quirk, or what it may do to me... What kind of Quirk gets inserted into my arm like some sludge?!
The other examinees were stretching and prepping their Quirks for the test ahead.
I looked around to get some advice. There was that girl from earlier, a brunette who helped me from tripping on my own feet.
Maybe she could help me. I began to walk up to her when I was stopped by a taller boy with a stern look on his face.
"She looks like she's trying to focus on the task at hand." He looked from her down to me.
"What are you going to do? Distract her from doing her best?"
I gulped. "No no no! It-It's not like that at all!" I said shaking my hands back and forth on my wrists.
"Leave her alone to focus. You should be focusing on what's to come yourself." The boy suggested rather militantly.
"R-Right." I said.
Not long later, the buzzer rang out and the large doors opened. Everyone burst forward and began to attack enemy robots for points...
But I was frozen to the ground!
My legs suddenly shot forward and I ran to find a robot to fight, but everywhere I looked the robots were already being taken down by the other examinees, all with impressive Quirks.
I gulped and started to panic.
"Look up!"
"Huh?! Who said that?!" I looked around to find no one around me. But I did notice a giant robot towering over the mock city trying to crush people below. Then it spotted me.
"Run."
"Who is that?!" Too late to care, I quickly turned around opposite of the robot reaching out to me and ran.
Then I forced myself to stop again once I heard a girl's voice cry out in pain.
I turned around to find the same brunette girl now with her leg trapped under a heavy piece of debris from the broken buildings, thanks to the robot closing in.
"Oh no! I have to help her! But how?!" I asked myself aloud.
"Clench your buttcheeks, kid. I got this."
"Huh?"
Just then, my legs moved without my doing. And everything got dark as something covered my head.
I could see...flashes... But I couldn't do anything as my own body leapt up as high as the robot itself, and landed a powerful punch in its face, crushing it inward and toppling the entire thing backwards.
Then I regained control of myself again, and could see clearly!
See clearly that I was now falling to my death.
The girl had looked up, along with who knows how many other people, in complete speechless shock.
I did one thing amazing, and I needed to reawaken whatever power that was that made me do that, and fast!
"You just need to ask nicely, y'know!"
Is this voice in my head?! Am I crazy?!
"Not yet. But you are going to die."
Gee, that's comforting!
"You have a lot to learn. Here."
My body felt itself covered by something again and my vision was again fuzzy as I landed on my legs.
Despite the fall, my body was unharmed.
And the girl was reaching her hand out almost like she was trying to help me.
Well now she screamed in surprise.
"Wh-What happened to you?!" She asked.
"Nothing! This is my Quirk!" The voice shouted to her.
I walked over, or perhaps the voice controlling me walked over, and picked up the large chunk of rubble off of her like it weighed nothing, flipping it on a side away from her.
"Now there should be enough time for me to-"
"AND THAT'S TIME!" The announcer shouted through the intercom.
I froze in place and felt the mysterious voice go silent as I regained control of my body. People around were staring at me. I chuckled nervously before exiting the mock city.
~~~~~~~
That night, I sat on the same beach and sighed in disappointment.
"I didn't get any points... I'm a failure..." I said to myself.
"I don't think so..." The voice returned.
"Oh great." I sighed. "Whatever power this is in me...it gave me schizophrenia."
Then, a gooey dark cyan mass grew out of the side of my body through my shirt and formed two white eyes, two large growths that resembled All Might's tall bangs, and a large mouth full of...sharp teeth?
"Oh what did All Might give me?! Am I hallucinating?..." I asked out loud.
"...What the hell are you?"
The mass smiled at me silently, then it spoke with the same voice from inside my head.
"I am Deku. And you...are mine." It said.
"H-How did you... Was that you making me jump up and punch the robot?" I asked stammering a bit nervously.
"Indeed it was." It leaned in closer to me. "Listen carefully, Izuku. You were not given me just to overthink everything twice then use me as a last resort. You earned this power to use in tangent with your ability to act BEFORE you think."
I nodded at it. Absolutely terrified.
"I am not a Quirk. Yet I chose long ago to be like one. When you are ready, I'll tell you why I made that choice...over others. For now, I will only heal your body and shield it from the damage that comes with this job...being a hero, so many times before we both succumb to the injuries... And it takes a lot of nutrition to keep me from simply eating you." It said.
I gulped. "S-So you're a..."
"Parasite?! No!... As long as you use me properly. What happened today, all my work, is not using me properly." Deku hissed.
"R-Right. S-Sorry about that..." I apologized.
"Now, keep your chin up. Your hopes of becoming a hero are not over. All Might went through the same thing himself when he first applied to UA." It said with a smile.
"Okay. Yeah... I hope you're right... Deku." I said.
"My first thought was correct... You are a loser, Izuku. Hence why I chose the name 'Deku'."
I frowned. "Great."
"But we can change that." Deku said. "First, where is the closest sushi joint around here? I'm starving!"
"Alright! There's one just a few blocks up the road." I said. "It'll be faster if you just-"
Deku frowned back at me.
"Right, right. I'll just walk us." I said submissively.
"Speedwalk!" He said, very impatiently.
