Never Mess with a Stark, Especially Tony

Summary: ** INFINITY WAR SPOILERS… duh ** When Peter disappeared something in Tony broke. Nebula and he return to earth in Quill's ship where Tony see Thanos, and traps him just before he disappears. No one was ready for what happened next. **NOT 100% CANON**

** 100% feels **

** Probably some percent crack **

Author's Note: As the summary stated this contents spoilers for Avengers: Infinity War. Major spoilage. This will, hopefully, have as much feels as the ending. This will not be 100% canon nor will it be completely to the script. I'll do my best to keep everyone as close to character, but except to see a bit of OOC. This is largely Tony Centric. Two-shot only.

DISCLAIMER: I own nothing of Avengers or other Marvel characters Stan Lee holds ownership to their existences. Anything else regarding Avengers are not mine either… and other disclaiming stuff, yada yada.

Enjoy!

Chapter One: His Heart

The battle was gruesome, and probably the most hectic that any of the warriors present had ever fought. They battled against creatures they have never fought never mind dreampt of ever seeing, but they battled on until finally it seemed the end was near. Then Thor appeared turning the tide in their favor. It wasn't enough. Those on Earth weren't aware of the battle happening on Titan. They weren't aware of the choice that one Doctor Strange made that would decide the outcome of this war. They weren't aware that Thanos had gotten to the Time Stone, and thus the sacrifice that Vision and Wanda had made was in vain.

He appeared before a weeping witch, and sympathized with the pain of killing a cherished one for he too had to rip away his own heart. Yet, in order to fulfill his life's mission he brought Vision back once again, and robbed him of his very soul. Wanda couldn't believe her eyes as she processed the grey form of her love. She missed seeing a zooming ax impale into Thanos. She missed seeing Thor push said axe farther into the purple man's chest. Thanos chuckled in pain as Thor loomed over him.

"I told you, you would pay for that." the thunder god said with barely disguised glee.

"You should've gone for the head." Thanos replied, and before anyone could move, he snapped his gauntlet covered fingers.

In result there was a gust of powerful energy as the stones carried out the unspoken demand. When Thanos awake from his vision it was to see that there was no longer an axe in his chest, and that his wish had already begun as he and those in the forest witnessed the once scarlet duo vanish into dust. Many more were becoming dust in the wind even those on Titan. Rocket wouldn't find out until much later that it was not just Groot that he lost. And Thanos wouldn't know what he had unleashed as one Tony Stark held one Peter Parker: AKA, Spiderman; AKA, Kid.

:: ON TITAN AFTER THE SNAP ::

After Thanos had disappeared from his home planet Tony sealed his wound, and breathed in relief as the pain dulled to a manageable ache. The billionaire turned to stare at Strange.

"Why would you do that?" Tony asked with confusion and anger, as he clearly remembered that Strange had said he would choose the stone over him or the kid.

Strange stared at Tony, stared into his confused hazel eyes, before saying, "We're in the end game now."

Before Tony could question the once neurosurgeon his was silenced as the sorcerer vanished into dust. Tony and the others stared in shock until one after the other the Guardians of the Galaxy on Titan began to disappear starting with Mantis. Peter Quill was the last of his present team to vanish.

"Sir…" a quivering voice called out, and Tony felt the bottom of his stomach fall.

Peter.

"Sir, I don't fell too good." the teen said as he collapsed against his idol, and Tony held onto the boy.

"Kid?" he whispered, as they fell to the ground.

"I don't wanna go, please sir… I don't wanna go…" Peter begged, whimpering as his body trembling as he clutched onto Tony.

Tony started at the kid, "You're not going anywhere, kid… you're right here."

"I-I'm sorry, sir-" and before Peter could finish, dust replaced him and the wind gently swept it away.

Tony started unbelievingly at the dust upon his hands of where Peter was just seconds ago. The only ones left on Titan was Tony and the blue girl that had appeared from nowhere during their struggle with Thanos.

"He's done it." she stated, her almost synthetic voice dripping in despair.

"No." Tony said, his fist clenched tightly, "No. There's still time."

"Terran. Thanos is gone, we have no idea where and he is too powerful." she said.

"Bullshit. His one man, alien thing, whatever!" Tony said, almost snarled, "His a purple alien ape with a powerful glove, yeah… but he's only one."

The blue girl watched as Tony began to stand before she replied, "And what is your plan? You're just one terran."

"I know for sure where Thanos will be going next. Earth. So take me there. Now." Tony stated bluntly, as he stood in front of her, his eyes burning into her black ones.

"It's suicide." she replied.

"I've cheated death before. What's one more?" he said.

The girl didn't bother to reply with words but just a firm nod. Together she and Tony ran to Quill's ship, and boarded. Assuming the driver's seat, she turned the ship on and dialed the destination to Terra.

:: ON TERRA SECONDS AFTER SNAP ::

The sudden blast caused everyone to lose their footing and fall to the ground. Okoye had been one of the few that went into the forest area where Thanos and the Avengers had gone into. She and her king. She laid upon the forest soil dazed until T'Challa came to stand before her.

"Get up, Okoye, this is no place to die." he ordered softly, as he helped her to her feet.

Once she was standing, T'Challa turned to dust in the wind right before her very eyes. Just one second ago her king was standing before her and in just a blink of an eye, if even that, he was gone. Okoye stared in disbelief before she heard the sound of others calling out for those who had disappeared.

Back with the Avengers, Thanos was smiling as he watched one after the other disappearing. Rocket called out to Groot as the teen sat slumped against a fallen trunk, and the raccoon yelled out as his best friend's son disappeared before his eyes. Before Steve's and the other's their teammates turned to dust. Steven had Bucky's dust clenched in his hands as he fell to his knees in defeat and disbelief. Wanda and Vision's body disappeared soon after.

"What did you do?" Thor asked, as he picked himself up.

"I saved this world." Thanos replied as he too stood, "And now, my job is done."

Just as they realized what he planned to do the Avengers began to run towards Thanos in hopes to stop him. They weren't expecting to fall again as the result to an earthquake, but it wasn't a magma induced quake. It was a ship landing on earth with hyperspeed. And from that ship came a disgruntled Tony and Nebula; which the genius later discovered was his blue companion's name. Thanos started in surprised that the Terran was left to live, but no matter his work was done and he made to leave if only he could stop falling on the blasted Terran forest. Thanos lifted himself up once more, but came face to glowing blaster glove with Tony right in front of him. Their faces close.

"Terran." he said simply.

"Purple ape." Tony replied with a snarl.

Thanos quirked his mouth up in an amused grin, "Came for one final hit?"

"No. I came for the Kid." Tony said.

"I'm afraid there's nothing you can do now," Thanos said as he raised his hand to activate a stone, "and it's time for me to go."

"I don't think so, bub." the genius said, and slammed his other gloved hand against the gauntlet.

Before anyone knew it, there was crimson red and gold claws dug firmly into the infinity gauntlet. Thanos was going nowhere.

"Release me, Terran." Thanos demanded.

"No." he replied, and punches Thanos as hard as he could.

The alien man's head snapped to the side with the unexpected force. Thanos turned to stare at the man before him in surprise, but all he got was more blasts and more punches. Once he even got a hard slap followed by a strong blast. The Avengers and Wakandains were rooted to the spot as they all watched a small man keep, perhaps, the strongest being alive rooted to the ground unable use the gauntlet. However, Thanos finally cleared his head from the shock and used his other arm to throw a punch at Stark expecting the Terran to fly back and release him. It did not happen. Tony Stark had rooted himself to the Earth. His legs were covered with his nanotech armor similar crimson and golden claws keeping him firmly down. Pain shot through him, yes, but the adrenaline and anger carried him on. Before his eyes, Thanos saw the Terran's armored hand had turn to sharpened claws. Tony grinned sadistically and stabbed his hand right down to the shoulder blade of the alien before him.

"Tony…" Steve and Rhodey called together in concern.

By the time Tony was done, Thanos had blood dripping down from his mouth and one eye was swollen shut. Finally, Tony let the purple man drop. His gauntlet still unusable with the claws wrapping themselves even firmer onto said glove.

"Hey guys, long time no see." Tony greeted as if he hadn't just beat up Thanos, "How've you been?"
