Sorry it took so long; I just kind of forgot I was writing this. ^^;

I wasn't sure how to write Bakugo for this section as well. I wanted him to come off as a young child with delusions of grandeur, hero fantasy and a drive to make Izuku/Izuka feel like dirt. Also, Mama Kat is protective of her 'kitten'. :P

It took a few days for Izuku to properly move out of her bed, though she struggled through the pain to get to her feet. After all, she had something to work towards.

The shock that All Might of all people would be acting as her foster parent had been shocking, yet she had received the best news shortly after that surprise had been given. She was only going to be with All Might was temporary due to her mother not 'actually' being dead like most had assumed.

The villain that had taken her hostage had an odd quirk, though one no one expected. The villains scales secreted a vicious purple poison that didn't kill but instead slowed down whomever or whatever it touched. Not just slowed in movement either but slowed in a temporal sense. So far, the doctors were hoping it would wear off and Inko Midoriya would just wake up well and fine. However, that didn't seem to be happening so far as it had been three days since she last closed her eyes. After all, that poison wasn't meant to be injected and it had been absorbed into her already slowed body. She would wake someday yet that 'day' could be years from now.

Even if she wouldn't get an answer or be able to see her smile, Izuku was willing to struggle through her body pains and see her anyway. All Might, or as she came to know him as Yagi Toshinori, promised that he'd take her to her mother when she could walk down the corridor without aid.

They didn't anticipate Kat however.

The spirit following her in her dreams and waking world was a constant help. Whilst being usually snarky, condescending and quick to anger, she had shown concern for her 'kitten'. Using as much physicality she had as a ghost, she lent an aid to Izuku as she walked, giving soft words of encouragement along the way. She was also a big help getting her tail and ears under control, as they liked to move without her wishing too and often smacking random things off her dresser.

Most of this aid came to her after she had a certain incident two days ago, when she was permitted to have visitors. Inko Midoriya was good friends with a woman by the name of Mitsuki Bakugo, whom had come to visit her. However, that meant that a certain explosive boy had come along. It didn't take much for Katsuki Bakugo to find Izuku's room, the boy hoping to lay into 'Deku' and hammer the final nail in the hypothetical coffin for Izuku's dream of heroics.

It didn't work out the way he wanted, Kat made sure of that.

-~~~TWO DAYS AGO~~~-

Izuku was sitting upright on the side of her bed, reading through one of her many hero notebooks when she heard the voice, her ears perking up whilst her eyes shrunk in fear.

"Hey Deku! What kind of crap did you pull?!" Katsuki explained, his bright blond hair spiking with his explosive temper; "You get out for school and get some sort of bullc*** power up? You even screwed up so much you turned into a girl, huh?" He asked, strolling into the room with hands in his pockets.

Shaking her head, Izuku turned to face him, though scooted a little away from him; "Y-Yes, I'm a g-girl. Those boys even gave me a quirk. At least I think, as I'm a ca-"She started, only to be cut off by a rapid series of explosions from the boys' hands, having been taken from his pants.

"Cut the crap, Deku! You've always been powerless and useless, now you think having this quirk, you're suddenly better? You've just proven you're just as pathetic as you've always been. I heard about that power boost you got, it's supposed to make normal people like Heroes; but you got even worse!" He cackled, moving closer to the bed and laying a hand upon the quivering girl's shoulder, smoke rising from her gown.

Kat floated right beside her 'Kitten', growling furiously, attempting to take a swing at Katsuki. However, her hand just kept phasing right through him; "Come on, stand up to him! Call for help! Do 'something'!" She demanded, almost pleading with Izuku as the boy leaned in close.

Right near her ear, Katsuki whispered harshly to Izuku, loving how she didn't fight back; "You'll never be a Hero. You're just as much of a 'Deku' as always, if not more. I don't need you messing up my origin story so just give in and play with some dolls." He cackled.

It was too much, Kat seeing Izuku slump with tears forming in her eyes, her body nearly giving out from those words. Izuku had looked up to Katsuki Bakugo, though it seemed the boy didn't share the same feelings of respect.

Fur flaring in anger, Kat moved on instinct, trying to free Izuku from Katsukis grasp. The moment that she pushed against him and towards Izuku however, she felt something different.

Izuku's mental presence was always there, she could feel it. However at this moment, it was subdued. She was in shock, denial and depression. Her 'presence' for a lack of better word had taken the backseat of her mind, letting her fear and shame run wild. That was however, until Kat found herself staring through Izuku's now bright gold eyes.

Katsuki could immediately feel something different with 'Deku', though he the eye trick to look like a cat's eye was admittedly pretty cool. That was the only thought process he got before sharp pain rocketed across his face.

Howling like a cornered feral, Kat flung Izuku's hand across Katsuki's face, sharp nails racking across his right eye. Katsuki screamed in pain as he let go of Kat for just a moment, enough for Kat to leap from the bed and slam into his midsection and cleave two clawed hands across Katsuki's palms in quick secession, much to his surprise and pain.

Squeezing his hands, Katsuki prepared to get up and fight. However he winced when he tried to open his palms, much to Kat's delight; "You sweat something explosive right? What would happen if there was an open cut where it sweats? Your skin is safe, but everything underneath is fair game." Kat stated, yellow eyes glaring with a feral look.

Katsuki could only stare from the ground at the young girl standing over him, looking threatening even in a hospital gown; "What the hell Deku?! What did you d-" Katsuki started, only to be cut off by a rapid kick to his chin, the blond boy hitting his head against the wall.

"Now, you listen to me, TNT. I'm not this 'Deku' you know. That quirk that brought out the spirit animal? That's me. While Kitten prefers not to fight you, I don't mind making you bleed until the point gets across. Attack my kitten again and we'll have problems." She muttered, bending down to be face to face with him.

Growling himself, Katsuki pressed his faced against hers, both of them unblinking; "And what will you tell them when they come asking me why I have cuts on me, 'Kat'?" He asked bluntly.

With a smirk growing, Kat pulled back, only to leap back and climb onto the bed. Promptly getting back in, she turned towards the confused blond; "I'd be more worried what you'd tell the nurse when she sees a bedbound distressed girl having defended herself against a bigger boy that burnt her shirt." She offered, pointing to the blackened shirt patch on her shoulder.

That was when she slammed her hand on the 'Call Nurse' button.

-~~~PRESENT~~~-

With a small groan, Izuku slowly peeled out her legs from the bedspread. Thinking back to all the things she did with Kat's help, she knew she'd need to have a conversation of it. Looking to her right, she could see Kat watching her, a curious expression on her face; "Is there something bothering you Kitten?"

Nodding, Izuku lifted a leg back to the bed to face Kat properly; "Yeah. I've gotten better at moving now. I even cat use my tail right. It is only thanks to you though, so thank you," She offered sincerely.

"You are welcome, but there is more you want to say. Something about that Katsuki kid I'd wager." Kat started, sitting next to Izuku; "I'm still not sure how I took over your body, though at least I got him off your back. Why didn't you fight back anyway?"

Flinching at the question, Izuku glanced to her feet, as well as the tiny claws at the end of her fingers; "Kacchan is usually right, I don't have a quirk and the others didn't stick up for me. Though with you, I feel... Stronger? Maybe a little braver. Still, Kacchan was one of my best friends. I always looked up to him even before he got his quirk." She said softly, looking upwards towards the ceiling.

"Maybe one day, we can look each other in the eyes and see each other as equals." Izuku started before bringing her gaze back to Kat; "But for now, I have to work on being stronger. Let's use our new powers to be the best Hero!" She declared.

Her thoughts were derailed however when the door came sliding open, All Might strolling in with the bang of the door; "Izuku Midoriya, I AM HERE!" he declared, only to be met with an empty room, devoid of the child under his custody; "Midoriya?"

"U-Up here..." Came a voice from the ceiling, Izuku clinging to the plaster of the ceiling, her arms and legs spread across the white surface. All Might could only stare at the sight, a little unsure on how to react to such a thing.

However, he soon boomed with laughter, closing the door and moving underneath the girl; "You can come down Midoriya. I am sorry that I scared you my girl." He offered, sticking his hands out to catch her.

It took some doing, though Izuku soon got her claws to detach from the ceiling. As she fell however, she felt her body twist in what felt natural, though didn't look it. Twisting like a rubber band, Izuku was able to land her hands on one arm, whilst the other arm held her legs. Bent in an acute angle, Izuku landed in All Might's hands on all fours, much to her confusion.

Barking in laughter, All Might gently let Izuku back onto the bedspread, allowing her to get comfortable once more; "It's good to learn of your new abilities and body. However, I have business with you Midoriya. You're being discharged into my care. Your mother isn't well enough to care for you at the current moment and I took it upon myself to aid you in this trying time. I'm also sorry you had to deal with that boy earlier, I promise he won't come near you if I can help it." He offered, a small smile to his face; "However, there is one thing I must tell you. If you are living with me, there is something I cannot hide, though I trust you not to share it on the internet." He offered.

Confused, Izuku tilted her head to the side in a rather adorable way; "A secret? You can trust me, All Might." She offered, a small smile gracing her face once she finally let it sink in that she was in the same room as her idol.

Smiling, All Might took a seat next to Izuku, his gaze sinking to the floor; "As you'll be living with me, this secret can't be ignored. However, it is imperative that you don't say this to anyone or even talk about it online." He urged.

However, upon looking back to Izuku, he was baffled by the sheer confusion on the girls face. Cutely putting a clawed finger to her chin, she had tilted her head to the side and folded her ears back in clear confusion; "I'm... Imper-tive?" She tried, looking like she was struggling for a moment.

Chuckling lightly, All Might had to remind himself that although Izuku seemed to be a smart kid, she was still rather young; "Imperative, meaning it's very important." He explained simply, giving her a warm but approaching smile.

Ears flicking up, Izuku promptly nodded, her face cracking back into a smile; "Okay! I promise to never speak or say anything about it All Might!" She squeaked merrily.

"Nailed it. This parenting thing is easier than I thought!" All Might thought to himself, though continued on; "You see Midoriya, I recently come into a fight with a very nasty villain. I only barely healed, parts of me are very badly damaged." He started, feeling guilty as he saw the light within Izuku's eyes slowly start to fade with every word he spoke; "And unfortunately, they won't heal properly. I will get to be home a lot more to help you with anything you need as I have to get better as much as possible. If villains find out I'm weaker right now, they might try to be even more villainous than before. Can you keep it a secret?" He asked with a finger to his lips.

Ears perking once more, Izuku remembered the fact she was going to be keeping this promise. Even if she was sad to hear her idol was hurt, she was proud for the 'mission' he gave her; "Yes Sir!" She offered with the most pure of smiles, raising a hand to give a childish salute. All Might had to pause to implant that image into his mind forever.

Laughing softly, All Might nodded; "Thank you young Midoriya. However, you can't just call me All Might all the time. Please, all me Toshinori. If you have trouble with that, call me Toshi."

Kat looked down to Izuku whilst she processed that, smiling herself when Izuku raised her head with a proud smile. She had talked this over with Kat earlier and it made sense to her at the time; "Okay... Toshi. Then you can call me by my name too." She started, raising her head in pride.

"My name is Izuka Midoriya, though you can call me Izuka."

-~~~PRESENT~~~-

Elsewhere, a certain blond and explosive young boy was growling and snarling at himself as he let loose explosion after explosion in his room. Katsuki Bakugo had been in a rather bad mood ever since he was ejected from the hospital with his mother earlier that week. He had been framed and toyed with by Deku of all people and made to look like a cheap villain.

No, he decided. Not Deku.

"Deku doesn't have the guts to do that... It was that 'Kat'. She's the one who caught me off guard." He muttered to himself, looking down to the thin scratch marks left on his palms; "That wasn't Deku. Heck, Deku can't stand up to me." He stated bluntly.

Immediately after speaking, his head shot up in realization, eyes widening; "No one has stood up to me. Except Mom. Everyone knows I'll be great! But, she beat me, she won." He reeled off, eyes dilating a little.

Moments after, a wicked smirk crossed his face, his explosions lighting up the room with brilliant sparks; "Kat. I don't know who you are, though you've got yourself a rival. All the best heroes have a rival to beat, she'll do for now." He cackled to himself.

"GOT TO BED BRAT! IT'S ELEVEN PM!"

"FINE!" Katsuki shouted, growling as he slipped back under the covers, dreaming of fighting and winning his rematch against his 'fated rival'.

Sorry it wasn't much. I'll post a larger one next time now that Izuka is going to be moving in with All Might and isn't bedridden.
