A/N: I apologise in advance for the feels but I swear I'll make it up to you! I'm leaving out Scott because there are kids involved and also Peter Parker because they basically are kids.

Clint Barton/ Hawkeye

Clint was meant to be home from his mission yesterday but he got delayed. As he walked up to the door, he was so excited to see you. When Lucky didn't come to greet him, he already knew something was wrong. Clint began searching the house when he found Lucky lying halfway in the bedroom doorway. The poor dog had given his life to protect you but sadly it wasn't enough. When Clint found your body in the bedroom, he completely broke down. Why didn't he come home sooner? He could've protected you. As Clint held your cold body in his arms, he swore vengeance on whoever did this to you.

...

Tony Stark/ Iron Man

You watched from the sidelines as Iron Man faced off against a bad guy. You laughed at your boyfriend's many witty remarks. The baddie saw his opportunity and took you as his hostage. This immediately made Tony shut up. He managed to reason with him and he let you go. As you were running towards Tony, you were shot in the back of the head. Tony saw red and charged at the guy and he savagely beat him to death. When it was over, Tony removed the suit and held you in his arms sobbing.

...

Pietro Maximoff/ Quick Silver

It was one Pietro's worst nightmares come true, but for once, it wasn't you that was the reckless one. When you were driving, you were usually very careful. On your way to work, you were t-boned by another driver and the impact had crushed your legs. You knew if they tried to move you that you would bleed out so you called Pietro and told him what had happened. He sped out to the scene of the accident. Pietro wanted them to free you but it was no use. You both said your goodbyes and when you felt like you were ready, they moved the car. He could only hold your hand and helplessly watch as you faded away before him.

"We were supposed to get married..." he sobbed.

...

Thor Odinson

Ever since Odin had given you his blessing, you had been spending more and more time in Asgard. Thor had even taken you to a couple battles. You were in the middle of one such battle with some creatures that were threatening Asgard. You had taken a few of them out when you noticed their leader advancing towards Lady Sif. She had her back turned to it so she didn't see it coming. You knew better than to take on the leader but there was no time.

"Lady Sif, watch out!" you screamed. You ran towards her and shielded her as the creature swung its mace. The force of the impact cracked your armour and with it weakened, the creature drove its sharp claws into the soft point. Thor had seen too late to stop it but he shot lightning at it and swung Mjolnir, killing it instantly. With their leader gone, the creatures fled. Thor swept you up in his arms and called for Heimdall to open the portal. He raced you to the healers but it was too late; you were gone. Lady Sif watched as Thor fell apart. If only she had been paying attention. It should have been her in your place.

...

Sam Wilson/ Falcon

A friend had called you up in tears, saying that they couldn't take it anymore. You went to them and managed to talk them out of jumping from the ledge they were standing on. Unfortunately as you were climbing back in, you slipped and fell. When Sam got the call, he was absolutely distraught. Your friend blamed themself for your death, and Sam blamed them too. If it hadn't been for them, you would still be alive.

...

Natasha Romanoff/ Black Widow

You and Natasha were on a tough mission to disable an enemy base. Your team had successfully completed the mission and as the two of you headed back to the rendezvous point, neither of you saw the sniper. Just as you had got there, you felt a sharp pain in your back. Nat looked around for the danger and you fell to your knees. Fortunately Clint had spotted him and took him out. Nat knelt by your side and held you in her arms. The bullet had punctured your lung and your body went into shock.

"Come on Y/N, you're gonna pull through this. You're my tough girl." Tears filled her eyes as she saw how pale you had become.

"Not... this time Nat... I'm sorry," you wheezed. Clint carried you into the jet to get you to help but it wasn't enough. Although she wouldn't allow herself to show it, your death shook her to her very core.

...

Bucky Barnes/ The Winter Soldier

There was a fight in the middle of the bar. You jumped over the counter and broke it up but one of the participants was not happy. When your back was turned, they swung a punch and it landed at the base of your neck. As you fell, your head hit the hard floor. When Bucky got the phone call that you were hospitalised, he rushed to be with you. The doctors did what they could, but you were declared brain-dead. Even if your head hadn't hit the ground, you would've been paralysed for the rest of your life. Your family had made the decision to turn off life support. Bucky's light in the dark was snuffed out. He knew one thing was certain; he was going to find the guy that did this to you and get his revenge.

...

T'Challa/ Black Panther

You were giving birth to your child. Your husband T'Challa nervously paced the waiting room as he waited for the news. As the doctors cut the umbilical cord, you felt as though something was wrong.

"She's starting to haemorrhage!" You tried to hold on, but you felt yourself slipping away. At least you had safely brought your child into the world. Despite their best efforts, the doctors were unable to stop the bleeding. T'Challa smiled when the doctor came out but it faded when he saw the look on her face.

"I'm really sorry Your Majesty, but your wife had passed away." He was in absolutely shocked. "Fortunately, your baby is well and healthy." T'Challa was relieved to hear that but he still couldn't believe you were gone.

"Can I see Y/N?" The doctor nodded and led him into the room. Your eyes were closed and you looked so peaceful that you could've been sleeping. T'Challa leant forward and kissed your forehead.

"I promise you that our child will not forget about you my love."

...

Steve Rogers/ Captain America

Today you were testifying in court. It was the final day of the trial and you were proving through evidence that the accused was guilty. Steve was watching you in the audience and impressed with the way you worked. The judge gave his verdict and the man was going to jail. Furious, he broke away from the officers, grabbed one of their guns and shot you in the chest. Steve rushed to your side and scooped you up in his arms, rushing you to the nearest hospital. Sadly, you had lost too much blood and all the doctors could do was declare you dead on arrival. Steve completely broke down. Why was everyone he loved taken away from him?

...

Loki Laufeyson

You were attending a banquet in Asgard. As you were eating, something didn't feel right. You felt pain shoot through your system and it was becoming increasingly difficult to breathe. Loki noticed you were struggling and called for attention.

"She's been poisoned!" There was nothing Loki could do as the poison spread through your body. He could only hold you in his arms and press his forehead against yours.

"When I find who did this to you my dear, I will put an end to them," he swore.

...

Wanda Maximoff/ Scarlet Witch

It was a freak accident. There was a gas leak and when there was a spark, the entire block was taken out, including the store that you were working at. Wanda was patently waiting for you to come home from your shift when Pietro approached her with tears in his eyes.

"Wanda... I think you should see this." He turned on the news and when she saw the charred remains of the shop, she completely fell apart. She let out a scream and her powers went haywire. Wanda clutched at the ring you gave her, feeling completely broken hearted.

...

Bruce Banner/ Hulk

You had contracted a horrible disease. Bruce had been watching you suffer for the last month, wishing there was something he could do. He wished he could hold your hand skin to skin but he had to wear a hazmat suit to avoid contamination. Your breaths were becoming slower with each one you took and your heartbeats were becoming further apart. Finally, the monitor let out one continuous beep. All Bruce could do was cry until he was out of tears.
