Todoroki x multi quirk reader

First day

I wake up to my german shepard Sam licking my face. "Aw geez Sam, ok I'm up." I say pushing her face away.  She was basically full grown and was a bit heavy. She pushes her paws on my chest and pushes me up. She was excited to finally see me off on my own. I get out of bed and go over to the bathroom. I get a shower and wash my hair. After that i put on my uniform and bring a bag to put Sam in. She had a quirk that allowed her to shink her size. She shrinks and firts inside the bag. I grab both my book bag and my hand bag and leave the house. I walk down the street and see a young man, about 15-16 with dark green hair running down the sidewalk. I see he has the male uniform for U.A. on and decide to follow him. We both arrive at U.A high and walk in. I find my class, 1A and sit down. Sam pokes her head out and looks around. She looks up at me and makes a little arf. I smile and tap her head as she puts her head back in the bag. Class starts and our teacher walks in and tells us to get dressed in our gym uniforms and to go outside. We all walk to the locker rooms. I bring Sam and set her down. I unbotton my top and begin changing into the gym uniform when i hear a cute aw. I look over and see a few girls looking at Sam who was asleep in my bag. I change completely and get sam out of my bag. She wakes up and happily greets me from her nap.i leave my bag and bring sam outside with me. Aizawa begins talking when he noticies me with Sam. "Y/n why do you have a dog with you?" He asks. "She's my Service dog Sam. Dont worry she's well behaved." I say putting her down. She immediately sits down and waits for my signal to transform. I give her the signal and she grows back to her normal size.
(Picture up top.)
She lays down and looks at the teacher. He moves on and describes the quirk apprehension test.

Large time skip to ball throw

My name gets called and i step up to the plate. I inhale and exhale deeply. Sam lets out a supportive bark and i look back at her. I smile and reel my arm back to throw. I use my air quirk at the last possible second to hurl tje ball 898 meters. Sam runs over to me and wags her tail, happy that I completed the tests. I walk back and watch as the same kid from before goes up. I over hear two kids talking. "No way he's a quirkless bastard." I overhear a spikey haired blonde say. I sigh and watch him throw the ball 705.3 meters. I smile and bend down to Sams level. I see the blonde running at the green haired kid. "Sam go!" I yell pointing at them. Sam runs at the spikey haired kid and blocks him from attacking. She growls at him, bearing her teeth at him. He backs off and goes back to his spot. Sam trots over to the green haired boy, his finger broken and purple. She looks at him, worried. "Classic Sam." I say walking over. I look around for the steongest flower and find a rose. I places the rose on his finger and have sam whine. A tear drips from her eye and his finger instantly heals.
"W-what did you-" i cut him off and walk away, going back to the changing rooms. I change back into my normal uniform and walk to my classroom. Students begin coming into the classroom as the bell rings for lunch. Sam hand me my bento I made and i grab some packaged meat from my bag to give to her. I unwrap my bento and begin eating as i unpackage the meat. I give it to her in little strips while I eat. I the decide fuck it and give her the whole thing, setting thr packageing on the floor for her. She waits until i give her the signal that she can eat. I point to her and she start eating. I smile and continue eating when a certain spike head walks in. Sam looks over at him, keeping an eye on him as she eats. I ignore him and soon he's directly infront of me. 'Well fuck.' I think to myself.
"Control that mutt of your's. We dont want her attacking soneone and getting put down." He says with a smirk, like he was actually gonna get her killed. I stand up, showing im not afraid of him.
"Look kid, i dont know who you think you are, but 1. You will not get my dog killed, and 2. Control your temper, I've only been here for a few hours and i already don't wanna be near you, or even talk to you. Bye." I say sitting back down. He grabs the collar of my shirt as Sam starts growling. He shoves her to the side with his foot.
"Listen here, talk to me like that again and I'll kill you." He says basically choking me. I smirk and use my ice quirk, poking him in chest as ive begins spreading on his body, slowly freezing him.
"Ill have you know, most of my quirks can be lethal, so id watch out." I whisper in his ear. I retract the ice and go over to Sam. "Samantha, are you ok?" I ask her. She gets up and shows she fine. The spiked haired kid walks out of the room and i sit back down with Sam. The green haired boy from before walks over to me.
"That was pretty cool what you just did. No one really stands up to Bakugou like that." He says.
"So that assholes name is Bakugou. Ill make sure to write that on my hitlist to give to my friend." I say jokingly. The boy freaks out.
"Dont kill him!" He says freaking out.
"Dont worry i was just joking." U say laughing lightly. "I'm y/n l/n." I say putting out my hand.
"Izuku Midoriya." He says shaking my hand. I smile at him and look down at Sam. She puts her paw on his leg and looks up at him. Izuku looks confused for a minute.
"She wants you to pet her. Go ahead, shes off duty right now." I say. He pets her head which she absolutly loves. She licks his hand and playfully nips at it. I smile at her and wrap up my bento. I put it in my bag and take out Sam's collar and leash. "Wanna cone with us for a walk?" I ask Izuku. He nods his head as i put the leash on Sam's collar. We walk out the classroom and walk outside. We walk around the school campus for a bit until we hear the bell ring. We realized we were kind of far away from the building and wouldnt make it in time. "Sam transform." She transforms into a large dog, able to carry up to 3 people. I get on and have Izuku hold onto me. He does so and we take off. Sam runs up tk the school and stops at the main door. I get off and have her transform back tk her normal state. I walk in with the two and we arrive a few minutes late.
"Explain why you are both late and covered in hair." Aizawa sensei says to us.
"We went for a walk and realize we wouldnt make it back unless we rode Sam. She canboth shrink and grow at will." I explain. He tells us to sit down an we do so.

Time skip.

I grab my things and grab Sam's leash. We begin to walk out the door when we see that Bakugou kid messing with Izuku. I take off Sams leash and send her after him. "Level 2 and nothing more!" I yell. She runs at him, biting down on Bakugou's arm. It was enough to cause some pain, but not enough to break the skin. I help Izuku up to his feet. "Seriously Bakugou? Why do have the need to bully him?" I ask. He just gets up and leaves.
"Its been going on ever since elementary school. I'm quirkless." He says.
"But what about the exams?" I mutter.
He walks away as I grab Sam's leash and attach it to her collar. We walk home and get comfortable. I decide to scroll through my phone and see some news. "*sigh* another villain attack girl." I say to Sam. She makes a sort of annoyed bark. I laugh lightly and turn over to her. I pat my side and she hops up. I get off the bed and change into my PJ's. I walk back over and cuddle Sam until I fall asleep.

So what did y'all think of the first chapter. Lemme know in the comments.
