Warnings: Blood, Injury, Swearing, Angst
Backstory: Based on the fact that MCU Peter Parker is in fact stronger than not only Bucky, but also Steve and probably almost as strong as Thor. (He definitely can lift more than fifty tons, probably more like 1,800 metric tons if you wanna be realistic with science, force, and shit like that). Peter misses out on a tour of Stark Industries, and turns out to be on patrol the whole time. Post-Homecoming, Post-Ragnarok, if the Asgardians returned to Earth instead of being in space for a long time.
When a class from Midtown that included Ned Leeds, Michelle Jones, Flash Thompson, and others went to Avengers Tower for an exclusive tour, it wasn't a surprise that something went wrong.
Surprisingly, though, it wasn't started by one of the students.
Tony Stark himself had been giving them an in-depth tour of Avengers Tower, showing them his personal lab that he apparently shared with his personal intern who he chose not to name - at first. Flash had been gloating the entire tour about how Parker hadn't even tried to deny his lie, until Stark told the group about how his brilliant, incredible personal intern and protegé, Peter Parker, worked not only on Stark's own inventions, but Avengers tech.
Right as they'd stopped in one of the common rooms that existed every fifteen floors or so, Stark got a phone call.
"Bruce?" He asked, brow furrowed. Something the other person said suddenly made him go sheet-white and he interrupted, saying, "I'll be there immediately." Hanging up, Stark shoved his phone into his pocket and raced for the elevator. "Stay here!" He shouted at the group, and disappeared.
None of them listened of course. They waited to see what floor the elevator had stopped at before calling it down and following Stark up.
The doors slid open into a small hallway with a glass wall that opened into a medical bay. Stark and Bruce Banner were rushing around, getting a whole setup ready.
Moments later, the window opened in time for Thor himself to arrive with a tiny, red and blue body in his arms. "He is bleeding out," Thor gasped, transferring the body to the table.
The students could see Spiderman, limp, suit torn and bloody, unconscious on the table, before the two scientists sprang into action. Thor hung back, eyes filled with worry as Bruce cut away Spiderman's suit.
"Three bullets, two under his right ribcage, one in left bicep, cracked ribs on both sides, deep incisions across his chest and left thigh. Broken left ankle. Someone get Loki down here now!" Bruce ordered, and Thor vanished out the window again.
Blood was everywhere, as was scraps of familiar fabric. Stark eventually hung back, terror in his eyes and his suit covered in dark stains. But he didn't care, neither did Bruce.
A moment later, Thor returned with Loki. Loki hesitated over Spiderman's body. "I cannot put him into slumber without risking him not waking up. I can attempt to heal, but I am not very efficient and he has too much for me to repair alone."
"Heal the cuts on his thigh," Bruce ordered. "Tony, get Steve and Bucky here, too. We need people who can restrain him if he wakes up."
"They are already on the way," the voice of Friday said.
Each of the students watching were frozen. Spiderman was hurt, everyone was panicking, and there was blood everywhere.
Stark ripped Spiderman's mask off and chucked it aside, staring at the hero's face. "Pete, c'mon, kid, you're gonna be okay, we have everyone here helping!"
When they all saw the familiar curls and baby face of Peter Parker, Flash almost threw up.
Peter's eyes slid open and immediately squeezed shut again in pain as he cried out. Quickly, Thor darted forward and took Peter's hand in one of his. "Squeeze if it hurts too much, man of spiders," he said.
Immediately, Peter did so, knuckles going white, and his back arcing off the bed as Bruce tried to keep the bullet wounds open. Thor grunted, face scrunching up and a definite crunch sound filling the air.
Captain America and the Winter Soldier skidded in from an elevator on the opposite side of the room. "Shit," Bucky breathed, seeing Peter. "Okay, uh, what can we do to help?"
Bruce gritted his teeth. "Steve, hold the entry points open so I can get the bullets out before he heals around them. Bucky, let him try your arm so Thor can have his hand back."
Clutching his definitely broken hand, Thor winced as he traded spots with the supersoldier. Bucky slid his vibranium arm into Peter's hand and braced himself.
Peter screamed as Steve helped Bruce. A look of horror came over Stark's face and he paced back and forth near the wall.
"Two out, Loki, focus healing here, Steve, move to his right bicep."
The third bullet came out a minute or two later, Peter screaming his throat raw the whole time. Bucky gasped as his arm was crushed in Peter's grip.
Flash threw up in the nearest trashcan.
Eventually, Peter passed out, and Bucky was able to extract his destroyed arm. No one could move as Bruce and Steve wiped off the blood from Peter's body, propping him up on pillows.
Then Stark turned to see the class watching through the glass.
A/N: More angst with Peter. Also Iron!Dad and protective Avengers. Loki is Peter's friend and is sorta a good guy. Yeah.
