Tony
Tony basically flew around in a metal computer. Of course he made sure it was protected against EMPs.
So he's more surprised than anyone when his machine suddenly shuts off in the middle of a battle after the mad scientist does...something and he starts falling to the earth.
Let's rewind. Two hours ago, there'd been a call to assemble. A Dr. Mad (super original, right?) had decided to take over the world with robots, starting with NYC. It was basically the Chitauri invasion all over again: the Avengers against an army that was led by a psychotic ass, only without Hulk punching Thor (such a shame).
Tony had locked in on Dr. Mad's location. He was using his company's building in Manhattan to control the robots, which were nasty cyborgs with automatic weapons and a full encyclopedia of martial art techniques from around the world. Even Natasha was having a hard time with them.
"Thor, can't you use your lightning to take these things out?" Cap asked over the coms.
"I am," Thor replied. "But if I use much more power I fear I'll render the city to dust."
"Don't worry about it, Goldie. I think I see Papa," Tony said, zooming in on Dr. Mad's building. He was on the roof, probably to make sure the radio signal wasn't disrupted by anything.
That's when Dr. Mad pressed a button on his control panel that did a thing, and now Tony was hurtling to the earth, his suit dead.
"Tony!" Clint called, panicked.
"Suit's down!" Tony gritted out.
"Thor, we need you!"
"I am too far!"
"Where's Hulk? We--"
A web latched onto Tony's armor, and he started swinging instead of falling, before being gently lowered to the ground.
Tony pulled the release on his suit and stumbled out of it, panting hard. "Christ."
"Tony?" Cap called.
"I'm good. I'm grounded, but I'm good." Tony poked at the webbing on his suit. "Uh, I don't know..."
"Hey, Mr. Stark! Big fan."
Tony looked up. Spider-Man was on the side of a building, a few stories up, nothing but his sticky fingers and toes keeping him attached to the glass. "How's your neck?"
"My what?"
"Your neck," Spidey repeated. "No broken bones or any of that?"
Tony shook his head. He supposed it was a valid concern. If Spidey had webbed him up any other way, there was a decent chance he would've broken his neck.
"You wanted to get to the crazy doc's control panel, right?"
"Any chance I could get a ride?" Tony asked. He could've sworn Spider-Man grinned under that mask.
Swinging through the city on webs was awesome. Flying was great, but the ups and downs of the swings made the adrenaline in Tony's veins go off the charts. And he was practically naked in his t-shirt and jeans, no protection at all if something went wrong, not like the security blanket that was metal armor. (Granted, his armor hadn't really helped him five minutes ago, but still.)
Spider-Man dropped him on the edge of the building, away from Dr. Mad and the five robot guards he had with him. "I distract, you do computer magic?" Spider-Man offered.
"Sounds good."
"Are we really trusting this guy to do this?" Clint asked over the coms. "He does low-level thugs and muggers. This is a bit above his caliber, don't you think?"
"Hey, doc!" Spidey shouted, on the other side of the roof from Tony. "Where'd you get the tech? Apple or Best Buy?"
Oh, wow. Dr. Mad was doing exactly what Tony would've done if anyone had compared his tech to friggin' Apple and goddamn Best Buy: sent all five guards after him to destroy his ass.
While Spidey danced between the robots' bullets, Tony crept up behind Dr. Mad and knocked him out with an elbow hit Steve had showed him. Dr. Mad went down like a rock.
Forty-three seconds later, all the robots were remotely shut down and Tony had Thor pick up his suit and drop it off at Avenger Tower before SHIELD or some other villain could get their grubby little hands on it.
"Ah, shit."
Tony looked up and winced. A bullet had found its way into Spidey's bicep. Tony took his arm to get a closer look, then frowned. "Are you seriously wearing spandex?"
"Shut up! Not all of us are billionaires," Spidey replied hotly. "It's just a flesh wound. I'll fix it up when I get home."
"You know, you could drop by SHIELD medical," Tony suggested. "They'll patch it up for you."
Spidey paused for a moment, like he was unsure of what to do of the offer of proper medical attention. Then he shook his head. "No offense, Mr. Stark, but after the whole SHIELD-is-actually-Hydra thing, I think I'll pass."
"Wow. First of all, no Mr. Stark bullshit. That was my dad, and he was an asshole. Second, SHIELD was infiltrated by Hydra; it's not actually Hydra," Tony pointed out.
Spidey shrugged. "Tom-ay-to, tom-ah-to. I gotta go." He jumped off the roof, webs flying as he shouted over his shoulder, "This was a lotta fun. We should do it again after you fix up your Best Buy suit!"
Tony saw red. "You DID NOT!"
