You Will Pay

A/N: oof, this one's sad

Thanos.

Thanos fucking snapped and killed off half the universe, including half the Avengers, and especially Peter Parker, the innocent fifteen year old kid who had so much to live for. The boy who fought next to his mentor, Tony Stark, and ended up dying in his arms.

Tony wouldn't, couldn't, forgive himself until he made Thanos pay for what he did. But at the moment, his anger was masked by grief and sadness as he and Nebula rode the spaceship back to Wakanda.

When Tony stumbled out of the ship, his abdomen covered in the medical spray he had used to fill the stab wound, his hands covered in blood and his kid, the Avengers were shocked he was even alive.

"Tony!" Bruce exclaimed, rushing to his teammate. "Where's the Spider kid?"

Tony choked on a sob, holding his shaking fists out. Bruce's heart broke seeing his friend so traumatized, immediately pulling the man in for a hug. "H-He..." he whispered, clinging to Bruce tighter, (if that was even possible.)

Bruce led Tony back to the other Avengers, helping him sit down on the grass. Everyone was quiet for a long time when suddenly a loud boom was heard, shaking the ground. The Avengers' heads whipped around to come face to face with the purple grape himself.

"Avengers," his voice rang out. "Now the world is perfectly balanced, like it should be."

Without warning, Tony stood up from his seated position, stomping towards Thanos, no one trying to stop him.

"You will pay for what you did!" Tony yelled, pointing at Thanos. The giant alien chuckled.

"And how will you do that, Stark?" he asked. Tony frowned.

"He was a kid." he stated, making the purple grape fall silent. "He was my kid. His name was Peter, and he was FIFTEEN, you monster! He had so much to live for, I tried sending him home but he was so, so stubborn- he wanted nothing more that to fight beside me, and he did."

Thanos and the rest of the Avengers were speechless as Tony continued to ramble on. "He died in my arms, crying because of the pain you caused him. He was the only one who felt it because he knew it was coming, and you put him through so much pain. His last words was that he was sorry for letting me down! Do you know how that feels?" Tony screamed. Tears dripped down his blood and dust stained cheeks.

"You will pay, for that. I will kill you myself, you fucking monster." And with that, Tony stormed off. Thanos stood for a moment, silent as can be until he used the space stone to vanish.

"Tony..." Steve began. "Who's Peter? And why was a kid with you?" Tony wiped at his eyes with his wrists.

"You've met him before, y'know..." Tony said, a dry chuckle escaping his lips. "He... he stole you're shield."

Steve's eyes bugged from his head. "Spider-Man is a teenager, Tony?!" he exclaimed. Tony nodded with a sniff.

"He was amazing. Intelligent, funny... he called me dad and I called him my son..." another choked up sob.

Natasha rested a hand on his shoulder. "We'll get him back. I swear."

Four years had passed when the Avengers had finally killed Thanos and reversed the snap. Civilians around the world began to pop up in their homes or on the streets, creating parades of joy. Tony and the Avengers were waiting on the streets, every single one of the back besides Peter. Then, a realization dawned on him.

"Oh my god. He'll be on Titan!" the billionaire exclaimed, pulling at his hair. "H-He's going to be so lost and-"

Tony was cut off by the roar of a spaceship above them, the craft landing twenty feet away. A small bridge popped out and the doors opened, revealing Strange and the Guardians. Quill was holding Peter in his arms. The younger's legs wrapped around the older's waist.

"Peter!" Tony shouted, breaking away from his group. The young hero's head immediacy shot up and he looked around frantically for the voice, a grin growing on his face when he saw his mentor.

"M-Mister Stark!" the kid screamed, wriggling out of Quill's grasp. He sprinted at Tony, catapulting himself into the billionaire's arms. "I-I missed you... i-it hurt so much," Peter mumbled into Tony's shoulder.

"I know, kid. But you're okay now."Tony rubbed the kid's back lovingly, ruffling his hair. He carried Peter back over to the Avengers, the Guardian's and Strange following close behind.

"Avengers, this is Peter, or Spider-Man." Tony said, setting the teen down.

"H-Hi!" he squeaked out. The Avengers chuckled before introducing themselves properly.

Now, the universe was truly balanced.
