Could you write an imagine where Loki turns Y/N's Boyfriend, T'Challa into an actual Black Panther. Y/N doesn't know so when she sees the black panther staring at her and walking closer to her she freaks out and maybe runs away from it thinking that it will attack her. But then Avengers explain what happened.
“Ms. Y/N, Sir has requested your presence in the lab”
You glance up at the ceiling, a habit you picked up from Steve and Bucky, “Any reason why?”
“I am not at liberty to disclose; however, it involves King T’Challa”
“Shit. Tell them I’m on my way”
The door to the lab is open by the time you get down there, and you practically sprint inside.
“Tony, what’s wrong?” You glance around the lab, “Where’s T’Challa?”
Tony chuckles, scratching the back of his head, “That’s actually the problem …”
There’s a soft sound behind you. You whip around, coming face to face with the largest black panther you’ve ever seen. Letting out a high-pitched shriek you scramble backwards, slamming straight into Tony’s work bench. “WHY … WHAT … HOW … TONY!!”
Tony groans, “I told you to stay hidden until I told her what happened! Now look what you did!”
The big cat hisses at Tony, but when it, he, turns back to you he lets out a soft, sad sound. “Tony, you have 10 seconds to explain why there is a panther in your lab, why you called me down, and where the hell my boyfriend is, before I completely lose my shit”
“Y/N, I really do have an explanation, I promise. The panther is … T’Challa”
Your eyes zero in on the panther, who lets out a soft chuffing sound, before walking closer. Slowly you slide off the table, and T’Challa hesitantly approaches you, “Babe? Is that you in there?”
Suddenly you have a lap full of purring cat, rubbing his face against yours. You look up at Tony, eyes wide. “Loki did it. We were out, responding to a call when Loki showed up. He seemed to take a particular interest in T’Challa, and decided to turn him into his namesake.”
You gently rub behind T’Challa’s ears, “How long will the spell last?”
“We don’t know for sure, but Thor said that Loki’s transfiguration spells usually last about a week”
“You’re gonna be a panther for a week” T’Challa snorts and lays his head in your lap, “Has anyone called Shuri? She needs to know about this”
“I was hoping you’d call her?”
T’Challa lets out a huff, nuzzling into your neck, “Fine. I’ll call Shuri, it’ll have to be a video-chat, or she probably won’t believe me”
JARVIS pulls up a holographic screen, already calling Shuri. She answers at the second ring, “Y/N. It is a pleasure to hear from you. I had intended to call you tonight, I have not heard from my brother in 24 hours. Do you know where he is?”
You chuckle, “That’s actually what I was calling you about. T’Challa was … turned into a panther, and will probably be this way for about a week” you rush. T’Challa sits beside you, in full view of Shuri.
“Brother?” He lets out a soft chuffing sound, “What happened to you?”
“Loki hit him with a spell at their last battle, tuning into his animal name sake.”
Shuri puts her head in her hands, “Damnit, brother, only you would get yourself turned into a panther”
“Thor said that the spell should wear off on a week, but until then he won’t be able to make any decisions regarding Wakanda.”
“Of course. You will keep me updated on any progress with the spell?”
You nod, “Definitely, we’ll call let you know if anything changes”
Shuri gives you a small smile, “Thank you, Y/N. However, I must go now, I need to inform the council what happened to their king”
T’Challa hums, low in his throat, “Goodbye, Shuri”
Having your boyfriend turned into a large, protective cat has its ups and downs. For one thing, you get all the cuddles you could possibly want, on the downside, he refuses to let anyone else near you.
“Y/N! Come spar with me”
You groan, burying your face deeper into T’Challa’s fur, “Do I have to?”
“Yes, you’ve skipped out on training because of T’Challa’s … problem. I can’t have you getting rusty”
Gently nudging T’Challa off of you, you and Steve head down to the gym. “I’m thinking we can spar, and then go for a run”
You and Steve quickly stretch and take your positions on the sparing match, T’Challa resting on the side.
Steve lunges forward, trying to use his size to overwhelm you. Fortunately, you had training with the Dora Milaje, and knew how to take down a man over three times your size. The sparing goes on for a while, everything is fine, until Steve actually lands a hit.
“Shit!” The punch lands right in your ribs, and suddenly Steve isn’t anywhere near you.
Steve’s pinned under T’Challa’s bulk, his teeth bared and poised over Steve’s throat, “T’Challa! No!”
You lunge forward, grabbing onto your boyfriend’s scruff before he rips the Captain’s throat out. Thankfully, T’Challa does get off of Steve, but he makes sure to keep you behind him. Steve sits up cautiously, “He’s heavier than he looks”
“Yeah he is. I, um, I think it would be best if we called it a day, Captain” T’Challa lets out another rumble, and uses his head to nudge you toward the elevator, “Alright! Alright! I’m going, babe. Calm down. I get it, no sparring when you’re not human.”
Eventually, the two of you end up in your apartment, T’Challa laying gently on top of you, making it so you can’t move.
“Did it bother you that I was sparring, or that I was hit?”
He gently nudges your side, where you can feel a burse already forming.
“I’m sorry I worried you” T’Challa huffs, nuzzling against you. “Let’s take a nap, kitty cat. I’m tired”
T’Challa settles on you more firmly, making sure that you are warm and comfortable. You can’t help but feel safe whenever your boyfriend is around, no matter which form he’s in.
You wake up decidedly more comfortable than when you fell asleep. Curling up on your side, you sniggle deeper into your blanket.
Shooting up, you look around your bedroom frantically, because you distinctly remember falling asleep on the couch with T’Challa. “T’Challa? Babe?”
The bathroom door opens and out steps your, now very human, boyfriend, “Hello, darling”
Eyes wide, you scramble out of bed and fling yourself into T’Challa’s arms. “I missed you”
His arms wrap tightly around you, “I was always with you”
You sniffle, tears blurring your vision, “I know you were, but you couldn’t hold me when you were a panther.”
“Do not cry, beloved, I am here now. Come, lay with me, I have missed having you in my arms”
“We need to call, Shuri”
T’Challa chuckles, “I will call my sister later. For now, all I want to do is lay in bed with you”
“Of course, I’d never say no to you”
You can T’Challa end up lying in bed for the rest of the afternoon. Curled up together, and comfortable, finally happy to be back in each other’s arms.
