(You have magical hugs that heal, but that person's injury appears on you.)
(VERY SAD)
You were a trained warrior from 來世 (AfterLife), a safe hold where people with powers could live in peace. You weren't sure why you were trained to fight because no one knew where you guys where, not even the residents. That was, until 2015 when a great fight between inhumans, humans, and SHIELD broke out.
After Life was destroyed, so you moved on and joined the Avengers. That was where you had met Valkyrie. There was an unspoken thing between the two of you. You would flirt all the time, but your relationship never went forward.
They never allowed you to use your powers. They didn't want to take a chance in loosing you; especially Valkyrie.
Now, you had to make a choice. The Avengers were fighting Doctor Doom, but things didn't go to plan. He had teamed up with Galactus and Carnage. Now, the Avengers where lying on the floor, close to death.
There was only one thing you could do, and you knew you could never survive. You walk over to Sam, and give him a hug. You smile, watching the gash in his stomach disappear, watching him revive. Until that happy feeling was replaced by pain. You screamed out, before falling to the ground.
"y/n! What are you doing?" Sam asks, cradling you.
"Being a hero," you whimpered, "Now I need you to fly me to everyone."
"I can't. You will never survive!" he said.
"I have to," you said, forcing a smile, "Please, I'll die a hero."
"No."
"Either way, I won't survive! With this injury, and the fact Doom is going to destroy this planet if you don't do something."
He got up, holding you bridal style before expanding his wings, and flying to everyone. Being smart, he went to the people with the smallest injuries first, and worst last.
Lastly, he flew you over to Valkyrie. You had blood dripping from every part of your body. Limbs were lost, bones were broken, and you couldn't speak.
Sam gently laid you on top of her, "We're gonna miss you, y/n/n."
You smiled at him, before hugging Valkyrie. When she regained conscious, she saw your almost lifeless body laying atop of her.
"y/n! y/n! What did you do?" she yelled, tears forming in her eyes as she carefully rolled you over to see your face.
"Save..." was all you could sputter out.
"No, no, no, no. You shouldn't have done that. We need you," she cried, stroking your hair that was matted with blood.
"I love you," you said, as your vision turned black and you started to loose control of your body.
"Stay with me! Don't leave! Please," she sobbed. She clutched to you tightly as if she could hold onto your life, as if her hug would take away the pain.
Your body went limp in her lap, and she picked your face up and kissed you. Her hot tears streamed down her face, landing on your cheeks. Her armor covered in your blood.
She kissed you again, smashing her pink lips into your pale ones. She didn't know what she was expecting. Maybe you still had life in you and your soft lips would kiss her back. Hell, maybe this was a Disney movie and the power of love would bring you back.
But they were cold, and you were motionless.
She wrapped her arms around you, letting her head fall as she sobbed; "Please... please..."
After a moment of sitting there, she stood up, and drew her sword.
She screamed. She screamed as loud as she could. The sound ripped through her throat causing it to start to feel raw. But she didn't care. The pain was numb. She couldn't feel anything except anger.
She ran towards Carnage, thrashing her sword around, cutting him into many pieces.
Though this didn't do anything to him, it felt good to hit something. Good to release the anger building.
Thor flew over and trapped Carnage inside a machine Stark had built.
He walked over to Valkyrie and put his hand on her shoulder.
"Go, we can handle this."
Valkyrie burst into tears as she cried, "I didn't get to tell her I loved her."
Thor wiped the tears off her cheeks and brought her into a hug; "She knows. I promise," he said, stroking her hair before a large chunk of concrete flew towards them, "Now go!"
She nodded, tears still dripping down her face as she ran back to where she left you. She picked you up, and ran off the battle field. It broke her heart as your lifeless body was limp in her arms.
Last time she was holding you, you were at the lake. You didn't want to go in, so she picked you up bridal style, and ran through the field, and dropped you in the lake. She jumped in right after, the both of you laughing and splashing around.
She was still hoping you'd wake up, try to shove her off you. Both of you toppling through the field, landing on top of each other and laughing. Hoping your eyelids would flutter open showing the beautiful colors and the love. Hoping your mouth would open to make fun of her for being so emotional.
But you just laid in her arms, lifeless.
