"Why are you being so mean? You're making him cry Kacchan! If you keep on hurting him... I'll uh- I'll stop you myself!"

"Heh, you wanna pretend to be a Hero? You don't stand a chance without a quirk, Deku."

Those words, those simple words moulded my life for the longest time. When I was just four years old, I was told the hurtful truth that I would never have any powers in a world filled with people wielding powers beyond imagining. My name was Izuku Midoriya, though once my classmates found out that I was 'quirkless', I was 'Deku'. The name was made up by someone I thought was my friend, Katsuki Bakugo. By taking the last part of kanji in my name, he read out the word he took as 'Useless'. Thus, I was so dubbed.

I never let it bother it too much, so I've told everyone. However, each time it was uttered by my ex-friend when we were just little kids, it felt a stab in the heart. He had promised that, before he got his quirk, we'd form our own Hero team and be the best that ever was! Better even than the No.1 Hero himself, All Might.

Just a year later, after he had his quirk and I was deemed quirkless, he told me straight to my face that I would never be a Hero. He even said I wouldn't even be a 'footnote in his back-story' once he made it to the top. Being without a power was one thing, losing the respect I had for someone was another.

I also had a thing for promises. My father said he was going overseas to work, to bring us money to support us, yet he never sent a single Yen. He told us he'd send a text message or email every day, promised me specifically that he'd be back for my next birthday.

5 birthdays have followed so far and we haven't even heard from him since he left.

Was it because I was quirkless? Was I just a 'Deku' to him like Kacchan says I am?

...Was Kacchan right?

Nine year old Izuku Midoriya sighed as he sat on his own, holding right arm as it stung from a recent explosive punch. Far away from him were the rest of his class, enjoying their recess. Among them was Bakugo, whom was showing off his acrobatic skills to his followers. They weren't allowed to use quirks during school time, though none of the teachers ever stopped the child prodigy.

Izuku shook his head to clear his thoughts of him before returning to his lunch, a lovingly packed sandwich by his mother; "Thanks Mom." He muttered to himself, a small smile gracing his features. Before he could dig into it however, he felt a small tap to his shoulder. Flinching, Izuku glanced over his shoulder to see two students above his age, looking 11 or 12. Maybe next year, they'd be in Middle-School.

One of them looked like he had curled bright blue hair, which wasn't that odd in this society since his own was green, though the defining thing from him was the cat-like whiskers seemingly printed on his cheeks. Next to him was another boy, though his own blond hair was long and falling, draping over half his face and blocking his right eye from view. This was the first time he had seen the pair, though Izuku wasn't much for socializing, so they may have been here all this time.

Before he could speak a word, the blue haired boy gave a warm smile; "You're Midoriya, right? We've been looking for you. My name is Ibacha Anima. This here is my friend, Kaiza Machiho. We're partners in trying our own business venture, though we need to run a few tests. Namely, we need help from you. You're quirkless, right?" He asked, his voice soft and wavy, as if he was speaking with the soft waves of the ocean.

Kaiza didn't speak much, though he gave a tiny nod whilst hiding in his hair a little from apparent shyness.

Blinking a few times, Izuku nodded slowly; "Y-Yes. I'm Izuku Midoriya. Why do you need me?" He asked, nervousness creeping through his voice, creating a stutter.

Smirking, Ibacha stuck out his hand, catching Izuku off guard and shaking his hand quickly; "A pleasure to meet you. Though for your question let's get to business. As you might have guessed, we're off to High school soon. As such, we thought to put the final plans of our career into full swing. You see, my partner and I have two very special quirks that we think could revolutionise the Hero industry." He praised, his chin stuck out far whilst he raised his head to the heavens in pride.

"Ok... So, what do your quirks do? And what does it have to do with me?" Izuku asked once again, brow rising in slight confusion from Ibacha's actions.

Looking back down to him, Ibacha coughed gently; "Uh, yes. Anyway. My quirk is simple, I can unlock the hidden potential within someone, bringing them to even greater heights. It's tried and tested, though I can only do it once a month. You know the Buster Hero? Airjet? He no longer needs that gaudy backpack to fly. Now he can fly with just the rockets on his back and feet." He explained, crossing his arms; "And my partner has a cool upgrade quirk too."

Seeing his chance to speak, the shy blond spoke up with a voice as squeaky as a mouse; "I-I can unlock someone's spirit animal. It depends on the person on what it is, though it's only temporary, it goes after a week. The spirit animal gives them special powers sometimes." Kaiza spoke, in barely above a whisper.

Always one to pay attention, Izuku soaked up every word, his eyes sparkling at the thought of such diverse quirks; "That's amazing! With powers like that, you could make Heroes much more powerful and be able to defeat powerful villains. I still don't get it, why do you need me?" Izuku asked, pointing to himself in confusion. Then, all of a sudden, it clicked.

"Wait, you mean..." He started, hope crawling into his voice.

Laughing, Ibacha nodded; "You got it Midoriya! We know what happens when it's used on someone with a quirk, as it unlocks their potential for said quirk. Though what if both 'Spirit Animal' and 'Unleashed Potential' are used at the same time on someone who's Quirkless? Even the Quirkless could gain the ability to become great heroes! Granted it may be temporary, though it would be a perfect test." Ibacha explained with a shrug.

-~~~Izuku Midoriya~~~-

"Midoriya, do you want to be a Hero?"

Before, the words Kacchan had said to me had rung through to me, yet Ibacha seemed to speak words much more powerful. Someone was offering me a chance. Someone was offering a chance to fulfil my dream.

Ever since I could remember, I have been inspired by All Might and other Heroes, wishing to be just like them. I took expansive notes on every hero, hoping and praying that one day, I could save people with a smile just like my idol. However, without a quirk, it seemed like a pipe dream. Now, two total strangers appeared in my life, willing to change that, even for a little while. Granted, they were using me as a lab rat, though I didn't care.

Tears flowing freely from my eyes, I chocked on my own emotions, nodding with barely any motor control to spare; "Y-Yes! It's all I've ever wanted!" I state with joy clear in my voice, jumping to my feet and letting my mother's sandwich hit the ground.

"Perfect! Now, this may sting, so don't move. Ready partner?" Ibacha asked, a wide grin stuck to his face. Reaching out and touching Izuku's right shoulder, Ibacha looked to Kaiza as he took hold of Izuku's left. Once set, the pair nodded in sync; "Ready? On 3. 1... 2... 3!"

That's when 'Izuku Midoriya' died.

It came like a switch was flicked, pain surging through my entire body and seizing it all together as if my body had turned to stone. I could feel the hands on my shoulders, the only sensation bar the pain searing into my nerves. I couldn't even scream! What was happening to me?!

Ibacha and Kaiza looked like they had seen a ghost, their arms yanking away from me, though their hands remained glued to my shoulders, as if they were permanently fixed. Wait, what's that?

My eyes shrank when they went cross-eyed, seeing my nose flatten slightly and pull away from my face, the tip turning a light shade of pink. Tearing my eyes from the change I could see, I could feel my body seemingly pull in on itself as it shrank slowly. Was I shorter? I thought this was supposed to make me stronger?!

The pain had reached its zenith and I couldn't take any more. Vision fading from my sight, I could only pray that I'd wake up to apologize to my mother for ruining the lunch she made for me.

The principal was livid, a stern gaze fired upon the two elder boys before him "And what were you boys thinking? Actually, I don't even want to know. Your parents have been called and this has been reported to quirk councillors. This is a grievous misuse of your abilities and you should be ashamed, using Midoriyas dream of heroics to your advantage. You've both been suspended and I don't want to hear of this again." He stated bluntly, shaking his head as he raised a hand, shooing them from the office.

The two boys looked to each other before they in silence. Yes, he'd never hear of it... At school at least.

With a sigh escaping his lips, the rattled principal took a single glance to the third and sleeping child that was now the only one left in the room. A once green haired young man once attended this school, though now he was replaced. The mixing of those two quirks at once had unforseen effects, creating a mutation rather than a temporary boost.

In Midoriyas place was a young girl, wearing clothes way too big for her now smaller frame. Her once pure green hair now was only half of the hairstyle, the roots of the hair a pitch black that only ended in a rich green hue. The front bangs of the young girl were entirely black, making the green hair look more like a dye job.

However, even if the gender change and the hair colour shift was tame, the fact the girl now sported an admittedly cute cat nose, a pair of dark green cat ears and a rather long feline tail seemed to take the cake. The boys that caused it could only assume that it occurred because the potential unlocking had interfered with the spirit awakening. It was just too bad that Midoriya seemed to have a female black cat as his spirit animal, as that had been what Machiho had told the principal. According to him, he felt that said female cat wasn't an overly pleasant one.

Once having been checked over by the nurse, they were informed the change was permanent due to the stable nature of her new body. They were lucky she wasn't completely malformed or even worse; on deaths door due to having organs of a feline in a body that rejected them.

In any case, Inco Midoriya had been called and she was to come and collect Izuku, perhaps have her checked over by a professional.

-~~~Inko Midoriya~~~-

Today just wasn't her day. I had left the house as soon as I got the call from Izuku's principal. He told me that an incident had occurred with Izuku and I was to collect him as soon as possible. Oddly, he seemed to mention my sons name a lot. Rather than say 'You need to collect him', it was 'you need to collect Izuku'. In any case, I figured it was another case of bullying. Perhaps they finally did something instead of having Bakugo Katsuki walk all over them.

Though, that wasn't on my mind right now. I had more pressing concerns.

A small crowed was around me as I tried to walk to the train station to get to my sons school, yet I couldn't pass through. Something was going on just ahead of me and the crowed was trying to shove passed. Barely keeping ground, I soon saw why when the crowed passed by me. Heading for the group was a large muscular man, his right side covered in purple scales that seemed to glisten in the suns light.

"You there! Stay where you are!" He bellowed at me, charging right for me in apparent desperation. I was not as fit as I used to be, so he easily caught up to me before I could even turn around. Crying out in panic didn't help, as I was soon lifted into his right arm, his lower arm gripping me around the neck.

It was like something had punctured my neck then and there, though I tried to break free, worried he was going to snap my neck. However, the man quickly turned instead, facing another large man, though slightly smaller than the other. He also seemed to be in pain somewhat.

However, it didn't take much to recognise him. Bright blond hair, barely visible eyes and a large white smile. All Might was here! He'd be able to save me!

"Stay back All Might, or the civilian gets it, yak hear?!" the large man yelled out in fear, seemingly bo0lstered when All Might seemed to fumble, one hand clutching right left abdomen. Was he hurt?
Such thoughts barely came to my mind, my thoughts growing heavy steadily, limbs falling weak.

What was going on? Why was I... The scales. They were leaking a purple liquid. Was that poison?!
"Foul villain, Grand Theft Auto wasn't enough for you? Now you have a hostage. Is there nothing you'll stoop to?" He asked in a loud and brave voice, taking a step forward.

Backing up, the scaled man tried to look fierce; "Stay back I said!" He bellowed, All Might stopping where he was; "No, just let me g-Arch! You Bi-!"

I broke free from his grip by doing something stupid. Not focusing on me, I had reached down and bit his arm as hard as I could. The moment I was free, All Might had swung in, calling out some American state followed by the word: 'Smash'.

Why was biting him stupid? The poison got in my mouth. It was already fast acting on contact, though once it went down my throat by pure reflex; I felt most of my strength leave me. All Might actually seemed to lose his smile as he bent down to me, trying his hardest to show his signature winning grin; "Fear not Citizen, I have... No, are you unharmed?" He asked, visibly shaken as he sees my body violently tremble, my senses growing weaker by the second.

"My baby... Izuku. I need to get to... Aldera." I coughed out, looking up to All Might in a pleading fashion. I could feel the last of my strength fading, my own sad smile coming over my face in the light of the situation; "Aldera... Find my baby." I managed, falling into his grip then and there, not a single breath leaving my lungs from then on.
