Peter got overwhelmed momentarily and Toothless saved him, demonstrated something other than distrust for the first time. Peter also met Dagur. The enemy numbers are falling steadily thanks to the Avengers.

You might hate me for this lmfao

Now:

It happens in the middle of the battle.

My spider sense goes off and I duck just in time, avoiding an alien jumping at me. I shoot a web and drag it to me, punching it as hard as I can and moving out of the way when its body drops to the ground. I then drop onto my back and kick both legs into the underside of a robot trying to attack me, launching it over me so that it collides with another robot.

I didn't see it coming.

Not stopping to breathe I roll onto my feet and web an alien in the face and pick up a discarded stop sign, slamming it into the alien quickly to end it, before shooting a web at an alien flying above and dragging it to crash on the ground. I avoid the bullets it fires at me as two other robots join it, and use taser webs to take them all down.

Nobody did.

Mr Stark fires his repulsors down onto the battlefield about a hundred feet away, destroying a handful of aliens that had been scrambling over cars. I web down an alien and punch another until it stops moving. I turn around to pick a new target, just to stop.

It happened so fast.

The aliens and robots in the immediate area all stop, standing still as a flurry of round, colourful lights form in front of me to be vague misshapen spheres floating at eye level.

"What the?" I barely even get the words out of my mouth before the colours converge into one big, blinding ball and launches at me before I can move.

"UNDEROOS!"

The last thing I remember is it hitting me.

Tony's POV

"Boss there is strange activity happening by Peter." FRIDAY informs me after I take care of a bunch of robots. I stop in place and look down for the kid, just to see dangerous looking energy or fireballs heading right for him.
Shit.

"UNDEROOS!" I shout, diving down for him. But the light strikes him, sending him flying through the air until he crashes into a car and falls to the ground. "Shit!" I curse, heading for him. Shit shit shit.

I land in front of him and reach for him, he lays facedown on the ground in front of the car, which has a huge dent in it. I turn him over, my heart in my throat. I'm going to throw up. Please don't be dead please don't be dead.

"Spider-Man is hit!" Cap says over the coms. I ignore all the chatter that follows.

"Scanning." Friday informs me. I shake Pete's shoulder, trying to wake him up.
"No time to be sleeping, kid!" I say, trying to keep the shake out of my voice. I let Friday auto pilot some of the projectiles in the suit to protect us, too focussed on the kid to be laying attention to anything else. No response. "C'mon kid." I hiss, beginning to pull off his mask. If I need to slap him to bring him round, I will.

"Scan complete." Friday informs me as I pull off his mask. He's definitely unconscious, and he's taken a few hits, but nothing looks too bad on the outside. "Boss his heart is beating irregularly, dangerously so."
SHIT.

"What even hit him?!" I shout, frustrated. "What was it?!"

"I do not know boss."

"Well FIND OUT!"

"Boss his heart has stopped, we need to shock it." Friday informs me and the colour drains out of my face. I am NOT losing this kid today. I press my repulsor to his chest and command Friday to run the protocol.

"3 2 1, Clear!"

Peter's body jerks from the voltage and I pull away. "Friday?"

"No pulse. Go again, boss."

I do so, and she counts down again. "3 2 1 clear!" I pull away again, but she tells me there's still no heartbeat. I press my glove down again. Movement catches my eye and I glance up as Friday counts down, just to see a spray of bullets heading our way. Peter's body jerks from the voltage.

I launch myself to cover Pete, but no bullets hit. I look up to see Cap holding his shield over us. He nods down at me. "We'll cover you! Keep going!"

"Friday, charge!" I exclaim, returning my glove to Peter. Come on kid.

"3 2 1, clear." Friday says, sending another shock to his heart. Mine feels like it could stop any moment.

"What's the matter? Lost, without your ward?"

If I were in a different place right now I could swear a distant voice would be sneering this, but like everything else around me I let it fade into the background.

Peter's POV

"Wake up!"

I jolt upright, trying to get a sense of where I am and what happened. The last thing I remember is seeing the light.

As my surroundings start to come together I notice where I am. The battlefield. But it's... hazy. Muffled. Everyone and everything is blurry. Except for one person. Someone stands in front of me in a long black cloak with a hood covering their face.

"Who— who are you?" I stand up. "What's going on?"

"I am no one to you. You are everyone to me. The very fabrics of your being are the bane of my existence. And yet... you are the driving force."

"I've never met you in my life!" I yell at the cloaked figure. "Or, I would know for sure if you'd show yourself."

The person chuckles. "The truth is, you are my enemy and I am yours."

"My crippling fear of abandonment?"

"Always the jokes, with you." I can hear the scowl in their face. "But I am not your enemy. Not this you. However every one of you is my enemy."

Dude's making no sense and I'm terrified.

Finally, FINALLY, he reaches up and lifts off his hood, pushing it back. My eyes widen once I recognise the person.

"Dr... Dr strange?"

"3...2." I look around for the sound, but don't find it. I return my sight to the figure. To... Dr Strange.

He stares at me, his face stone cold. Chills run up my spine. "I don't understand."

"Oh, but I DO!" he exclaims with a bitter laugh. "I DO."

"3..."

"What's..." he cuts me off.

"My world was perfect. I had the perfect life out of ALL THE OTHER ME'S! ALL OF THEM!" He jerks his finger around as if accusing me of something horrible. "I HAD... I HAD CHRISTINE. I HAD MY JOB. I HAD MY FRIENDS!"

"O...okay?" I don't know what I am supposed to say to that?

"BUT...YOU?! YOU FUCKED IT UP!"

"3...2..."

His voice drops to a shaky, angry whisper. "It was ok. We won the battle. But then you had to go and die. That action threw over the WHOLE timeline. It was NOT meant to be you. And because it was?" He trails off, shaking his head. "Everyone suffered because of your desperation to be the hero. You snapped. You weren't meant to. But because you did? Tony went... he was unstoppable."

"3...2..1.."

"Relentless. He HAD to get you back. No matter the cost. THAT is why my world is in ruins, my girlfriend dead, my friends corrupted, my life GONE. He tore apart the world looking for answers in places he never should have. The timeline diverged. THEY came. Destroyed everything. What was once my home is now a big pile of ruin."

"Why are you doing all of this?" I ask. "Tony did snap. Here. And everything is ok. He is not your Tony. I am not your Peter."

"Don't you get it?!" He shouts, despair lacing his words. "It SPREADS. if I don't kill you, no one... no one will. I have to stop the infection."

"That's..." I stare at him. A few seconds pass, then I burst into laughter. "Ridiculous! That's just... I mean, come on, dude. You can hate me all you want, but it sounds like I did the heroic thing! And you're too angry that you didn't stop your Mr Stark from lashing out in time, so you're taking it out on me. The multiverse is real. I know that now. If there are infinite possibilities then why don't you just go to a universe where I didn't snap? Or...why didn't you go back in time?"

"3...2...1..."

I stagger to my knees, a pain shooting through my body.

"YOU DON'T GET IT!" He shouts. He's right in front of me now. "THEY FOLLOW ME EVERYWHERE. I CAN NEVER BE HAPPY. MY WORLD IS A BURNING HOT MESS OF RUBBLE. SO I... so I do the only thing I can do."

"3...2...1...clear..." the pain shoots through me again and I gasp for breath after it gets knocked from me.

"And what is that?" I ask him, voice rasp from the pain. "What is it that you can do? Necromancy is a bad idea; in case that's your idea, you know."

"I will hunt. Hunt every last one of you down and end you myself. The sooner you're gone from the universe, the sooner the sacristy can be restored. With no you ever there would be no risk. And they'll get me..." he gives a twisted, wicked smile and shakes his head. "But they'll get to me when the last one of you is on your knees at my feet, your head rolling on the blade."

"CLEAR."

My eyes shoot open and I jolt upright, gasping for breath as pain runs through my body.

"Oh thank fuck."

I clutch onto whoever is in front of me, bracing myself as I try to centre myself through the pain. They hold me tight against them, and I recognise the smoothness of metal. Tears of pain, confusion and despair after what I just saw run down my cheeks as I try to come to terms with everything. It feels like a fever dream. But it was so real.

My sight begins to come back to me and I find myself pressed against red and gold metal.
Is what he said true? Is he really going to... kill me? All the Mes?

My hearing comes fully back too, and I pick up on all the slings of the battlefield again. Including the coms.

"Spider-man is up!"
"Is Spider-man hurt? What's his status?"
"What even happened?"

But isn't the multiverse...infinite. Wouldn't that mean there are infinite me's?

"Kid. Can you hear me?"

At his words I pull back, recognising fully that it's Mr Stark I'd been clinging to like a koala bear. "I...yeah, Mr Stark. Oh my god."

"Kid I had to shock you about fifteen times. I didn't... don't do that again." He exclaims. He seems really freaked out.

"Yeah...yeah... I'm..."

"Spider-man?" I hear. It's cap. I go to turn towards the voice, but Mr Stark presses my mask into my hands and nods at the thankful look I shoot him. I didn't even realise it was off.

I pull it on then turn to Captain America as he walks up to us and away from an alien he'd been fighting off.

"What happened to you?" He asks, surprisingly concerned. I look between him and Mr Stark, debating what to say. Do I tell them what I saw? Who I talked to? Will they pass it off as delirium? WAS it delirium? I should tell them, right? Just in case it really WAS real.  

"I think... I think I just met who was behind this."

Ok so that was a wild ride. Fun as hell to write though (this is coming from 3 am me, I'm not sure future me will agree).

As it is 3 am as I write this, I do hope there are no mistakes. And if there are, I do hope they're funny.

I apologise that this is a few days late.

See you next chapter, with Hiccup.
