Author's note: I'm so sorry that I haven't updated this story in a long time! I couldn't think of anything ~

Loki glared at Thanos before turning to Sif. She had heard Thanos and nodded, seeing the panic in Loki's eyes. He turned back to Thanos, "What do you want?" he asked.

"For you to suffer..physically and emotionally. But...I'm going to toy with your emotions first." Thanos smirked.

Fear grabbed at Loki's heart, but he shoved it down. He masked his fear and anger, his face and eyes looking completely calm. Even though the rate his heart was going, he was freaked out. Thanos knew this and smiled coldly.

He heard Sif scream out his name, he gave one last glance at Thanos before running. When he found her, she was trying to fight off elves. As an out cold Thor lied on the ground. Sif glanced at him, "Get Thor out of here!" she said.

Loki nodded as he sighed. Not caring of the amount of strength he had, he flung Thor over his thin shoulder. Without even thinking, he grabs Thor's hammer and picked it up. He lifted it with ease as he walked away from the chaos. Sif was shocked. "So...he's finally worthy?" she whispered, before turning her attention back to the fight.

Loki got Thor to the Shield building. He lied his brother down and put his hammer next to him. He used his magic to fully heal the demi god and wake him up. Thor's eyes fluttered open to show two bright blue orbs. He looked at Loki and then slowly sat up.

"Did..you...who got me here?" he asked.

"Me." Loki replied calmly.

Thor glanced at his hammer. "Did you carry...?" he asked.

"Yes...I have no idea...how I did." Loki said.

Thor smiled, "Brother! You're finally worthy for it! Father will be proud." he beamed.

Loki grinned, "I guess so. Right now though, we need to focus on beating Thanos. I have an idea though."

"Yes?"

"You promise you won't stop me?" Loki asked.

Thor raised an eyebrow. "You aren't betraying me are you?"

"What? No! No...it's something else. But do not stop me...please?"

"Alright, I give you my word."

Loki nodded before getting up and running back towards Thanos. Thor stood up and grabbed his hammer. Watching his younger brother. "What are you going to do, Loki?" he asked into the air.

Loki stopped behind Thanos. He took a deep breath and focused. He could feel his magic surge through him, the static making his heart rate speed up. Thanos turned around to the hum of magic. He was shocked to see Loki. He was glowing green, with green bolts of electricity surrounding him, along with green flames and light. Loki opened his eyes, they were glowing emerald green, the power lighting them up.

He grinned at Thanos. "Good bye, Thanos." he snarled.

Thanos stared at him in confusion, then his eyes went wide with shock. He knew what he was going to do. Before he could stop him though, Loki let his power go.

Green and white light, illuminated the whole street. Bolts and flames surrounding it and crackling on the buildings. The surge of power was felt through everyone and everything. Loki winced as sharp burning swam through his thin frame. His Asgardian form melting away to reveal his jotun form. His burning red eyes reflected his pain and discomfort.

After ten minutes, the light dissapeared. Leaving stunned people and fighters in it's wake. Thanos was gone, in a pile of ashes in the middle of the street. Agents and fighters groaned and coughed as they stood up. Sif rubbed her head before scanning her surroundings.

Thor watched everyone get up, complete shock written on his face. Sif walked over to him. "What just happened?" she asked.

"I don't know...Loki said he would do something, and he told me not to stop him." Thor replied.

"Well, Thanos is a pile of ashes right now...so whatever that was...was probably Loki."

"He used up all his power." a man's voice said.

They both turned to see Odin, staring at them. He wise eyes filled with sorrow. "Father, don't tell me that Loki is..." Thor whispered.

Odin sighed and frowned. "I'm afraid so. He's still alive, but barely. Thanos is not dead, he'll be reincarnated in a hundred years. I need you to bring Loki back to Asgard." Odin said.

Thor watched as his father walked over to the thin body of Loki. Sif and Thor rushed offer, their faces unsettled. When they got to him, he was gasping for air. His eyes were wide with fear, shock, and pain, his skin a ghostly white, sweat soaking the edges of his raven black hair, his lips almost white, his body was shaking. Thor knelt down and gently picked his brother up.

"Father, please, we need to help him." Thor said, his voice cracking.

Tears pricked Odin's eyes as he watched his adopted son die. "I'm afraid we can't Thor, I can't put more power into his body. It will only kill him slower, it will cause an immense amount of agony. I don't want that for him."

"He has to have more power than what he just let go of! He picked up Thor and Mjolnir!" Sif said.

Odin nodded, "I know and I'm proud of him for that. But he let that power go too, it was very strong. He had to in order to destroy Thanos." Odin explained.

Tears was threatening to leak from Thor's eyes as he felt his brother shiver. He cuddled Loki close to his chest. "Then..let's go." he whispered.

The warriors three joined them, Thor told Fury that they'll be back to help clean up the damage. Fury nodded, "Take all the time you need...you look like you'll need it." he said.

Odin transported them to Asgard, where they were met by Heimdall. He glanced at Loki with a sad look, guilt washing over him as he remembered how much hatred he had thrown at the man. As they walked down the rainbow bridge, Thor kept feeling Loki shake in his arms. He looked down at his brother, Loki looked at him.

"I'm scared." he whispered.

Thor frowned, "I know brother, I know." he replied soothingly.

When they got to the city, everybody surrounded them. Begging for Odin to figure out something to help their youngest prince. Odin sighed as he fought back his tears. When they reached the castle, Odin lead them to the funeral room.

Thor saw his mother, Frigga, lying peacefully in her golden casket. Odin walked over to a man dressed in black. He whispered a few words before another golden casket appeared.

Odin told Thor to lie Loki in his bed until he passes and to be there for him. Odin walked out to get ready to explain to his kingdom that he can not help Loki. Sif and Thor walked towards Loki's room.

Sif looked at him, his eyes were starting to close as weakness took over his body. When they reached his room, Thor lied him gently down onto the bed. Loki coughed a little before tears fell from his eyes.

Sif stroked his cheek as he looked at them. "I-I don't want to...die." he said.

"I know brother, but why? Why did you sacrifice yourself?" Thor asked.

Loki swallowed, "T-to..save Asgard and...Midgard. I-I owed them...a-and you guys...th-that much." he replied weakly.

Tears raced down Thor's face, along with Sif's. "You could have asked me for help. We could have destroyed him together."

"We did...th-though. W-we did." Loki said before coughing.

After he was done coughing, he took a shuttering breath. "I-I'm s-sorry...I b-betrayed you...before." he whispered.

Both the warriors smiled softly, "I think you earned our forgiveness...a long time ago." Sif replied.

"I forgave you long ago, brother." Thor said.

Loki smiled before closing his eyes. They heard his last breath of air leave his body. They waited a few minutes before stepping back. "I'm going to get my father." Thor said.

"Go on." Sif whispered.

~3 days later~

"He died a hero, as so did my wife. Your queen and prince were very strong, wise, and brave Asgardians. Loki sacrificed all his power and his life, so that Thanos would not be able to reach us. Frigga, sacrificed her life to help protect Asgard. We owe them our lives, but also our love, care, and adoration. We will always remember them as our heroes, our family." Odin spoke.

Everyone had tears flow down their faces, in the crowd stood Steve, Natalia, Clint, Fury, Bruce, and Tony. Tears pricked all their eyes. The warriors three, Sif, and Thor watched with silent tears. They all cried as they said goodbye to their friend.

After everyone was done saying their last goodbyes, they closed both caskets and carried them to their graves. Both has golden stones, with their names, date of brith, and a little poem on them. After they were done being buried, they all went to the castle. To join the feast and celebrate Frigga and Loki's lives. Thor smiled as they made jokes, but he would never forget his loving mother and his intelligent, funny, and slick brother.

Sif walked out onto the balcony, and looked up at the sky. Two new and very bright stars shone brightly in the night sky. She smiled, "Looks like we have two new stars tonight. Rest easy...Frigga and Loki, my love." she whispered lovingly.
