3rd Person POV

The power stone in Thanos' left hand was inserted back into the gauntlet and it lit up, making the mad titan growl as he harnessed the power of all six stones.

Meanwhile, Y/N was staring at Tony. The time was running out. Y/N went to his pocket and took it out,

It was the arc reactor that Tony gave him two years ago.

"You take this and you hide."

Those words replayed in his head, and he shook his head.

Y/N: I've been hiding for too long... not anymore.

He stuck the arc reactor on his chest and tapped it, the nanotech from the mark 50 engulfing only his hand, he then began to creep up towards Thanos.

All that could go through his thoughts was Wanda and Jean, how by leaving them will make them sad. But benefit the rest of the universe, this was his chance to be a hero. So Wanda could look after their daughter in a safe place.

He got to his memories, Wanda finding him, giving him a new purpose, all the way to being the mother of his child. And his daughter, the sun in his life, he was grateful to spend time with his new best friend for two years, rasing her and nurturing her.

Maybe this was the right way to leave.

Y/N then tried to telepathically communicate with Wanda, before he spoke in his head, knowing she could hear this time. All while trying to get Thanos.

"Wanda, it shouldn't be you, but it is. I'm sorry we couldn't have much time together. But at least I know I brought you back... sometimes, God takes away the one thing that you need most in life. But I guess I'm already used to it by now. The key to my heart is just irreplaceable and the only true owner of it is you. Thank you for all the time you have given me... whatever you do, protect Jeannie... our little Phoenix, let her know that she's in my heart aswell... we have reached the end of our journey, but I will never forget you... I love you, Wanda."

It pained him to mention this, it was a final goodbye. He went full foward to Thanos who was just about to snap. Wanda hearing her lover's last words in her head, she began to rush towards him.

Y/N grabbed onto his gauntlet, stopping the snap as Thanos looked into the man who never gives up eyes. He was dumbfounded.

The soldier then attempted to scratch off the stones without Thanos looking, the mad titan eventually had enough and tossed the man away with a whack.

After getting rid off the Avenger, Thanos breathed heavily. Finally getting what he wanted. Balance.

ㅤㅤㅤㅤ

"I am... inevitable."

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ
ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

Nothing.

He turned the gauntlet to see the stones completely vanished, all gone. All empty. Thanos turned foward to see the man he feared, prevailing again.

Y/N felt the surge of all 6 stones, as he stood on his knees, taking in the burning feeling. His healing could not amount to the galactic power he was harnessing.

Everyone saw what was happening. Even Wanda, and she looked at him in an understandable expression. Her body went stiff as her heart tore into a million pieces.

ㅤㅤㅤㅤ

ㅤㅤㅤㅤ

"And I... am...."
ㅤㅤㅤㅤ
ㅤㅤㅤㅤ
ㅤㅤㅤㅤ
"The Wolverine."

-----------------------

After the flash, everything changed.

Armies, beasts and all sorts of alien enemies were being dusted away. All the heroes were in awe by what was happening.

And Thanos. He watched, shocked and regretful, knowing he shouldn't have interfered. Y/N had killed him once and now, he knew this would be his second time. His children looked down as they accepted their fate.

He took his last seat, taking the defeat. He failed. Because good will always prevail.

Slowly, the nightmare being the mad titan, was finally dusted.

Meanwhile, a weak Y/N collapsed to the ground, leaning his back against some rubble as he took a deep and difficult breath. The snap caused half his body to be burned, his powers of no use to save him.

He was dying any second now.

Tony landed infront of him, seeing the man who ended his anxiety. The brave weapon that was created by his father become something more, he gave a light smile, imagining how now because of his sacrifice, Morgan can live in a safe environment. He slowly rested his hand against Y/N's cheek, they both shared a mutual smile.

Tony: Friday.

Friday: Life functions critical.

He pulled away painfully, before Steve came in and told him it was okay and he did the right thing before giving space for Wanda. Who needed him the most.

Wanda slowly came close, in disbelief and shock. She only came back just for her lover to make the ultimate sacrifice, it was not fair on her. She took a knee down to him, holding her tears to be strong, seeing Y/N like this was pulling her apart.

Wanda: Y/N...

She began to slowly reminisce whilst looking at her soulmate.

Y/N: Wanda...

He murmured, looking up at his love, his life, the only woman he ever needed. He placed his hand in hers, as Wanda fought the urge to not break into tears. He gave a little smile, making Wanda force one too, she already had lost so much and for what? All because he needed to save the universe, one sacrifice in turn for billions.

Wanda: Y/N...

She softly said, making his eye contact direct to hers, she took in his E/C coloured eyes the ones she fell in love with for the final time. Her other hand went to his cheek, stroking it softly.

Wanda: We're going to be okay, I'll take care of Jeannie... I promise.

She lied, but only because she needed to reassure him. She wasn't angry, but she wasn't going to cope well. Only for her, it seemed that yesterday they were happily in Wakanda, living a happy life. It all went too fast for her.

Wanda: I love you too.

She replied to his telepathic message from earlier, she continued smiling until Y/N's body stopped turning, his breathing went silent.

He was gone.

Wanda continued smiling until that broke down into tears, her lip trembled at the sigh of him physically dead. Her head slowly went foward and she cried into his neck. He did this for everyone.

He was a hero.

Meanwhile, soft sobs from Steve, Natasha and Tony could be heard. Even the Hulk. They all lost someone they loved and cared about, someone they saw as family.

Starting with Natasha, they all took a knee. All the Avengers, Guardians and soldiers. Some may have not known this man, but he made a huge sacrifice.

Gods, aliens, royalty, galaxy travellers and all types of people were paying their respects to a small boy from Westview.

Wolverine saved the universe.
