Aloha! This chapter is a crossover with the flash! Uhm don't ask about the timeline because I honestly have no freaking clue about when this takes place so which ever season seems fitting for y'all. Also probably no spoilers on the flash especially not the last 2 or 3 seasons since I don't remember what happened in them. Enjoy!

Third Person POV

New York was being attacked. Again. So of course the avengers had to save the city. Again.

"Rogers! Got any eyes on the main weapon?" Tony yelled, flying around looking for said weapon.

"Not at the moment, no!" Steve yelled back over the coms, running around trying to find it.

"Uh- guys! I think I found it!" Peter shouted, swinging over Captain's head followed by a flying robot holding the cannon shaped weapon.

"Kid!" Tony gasped as Peter narrowly missed the cannon blast.

Flying as fast as he could, Tony desperately tried to get to his- the kid. As he got close enough to be able to grab him, the robot shot the cannon again, Tony being a second too late to grab him and Peter being a second too late to dodge the blast.

Instead of hearing Peter cry in agony, he- disappeared?

"Wha- Kid?!" Tony yelled, searching the ground he should've landed on.

"Stark! What's wrong?" He heard Scott ask from the ear piece.

"The- the kid.. he's gone?" Tony said, landing on the ground.

"What? As in gone gone? Or-" Scott got cut off.

"He disappeared. The cannon- he got hit by the blast and then just- disappeared." He explained.

"We'll find him, Tony. Let's just finish off this and then we'll search for him." Steve said, making Tony nod and fly back off.

\\Meanwhile//

"AAAHHHH" Screamed Peter as he seemingly fell from the sky and smacked face first onto the concrete.

Groaning, Peter slowly stood up, rubbing his nose. "Ouch." Is all he could say, looking around.

"Where am I?" He looked to his left where a large building sat with the word 'STAR' on it.

After retracting his suit back into his watch he walked up to the door. Once he realized it wasn't locked, he cautiously walked in, looking for someone to help him.

"Hello?" He called out as he walked down the corridor that led to a big room with a crap ton of computers and monitors along with a mannequin leaning on a stand with a red suit on it. It looked pretty cool.

Once he got over the shock, he looked over and saw a man with long wavy black hair looking at him weirdly.

"Hi?" He waved awkwardly.

"Who are you?" The man said, pointing at the teen.

"Uhm- Peter Parker." He answered. "I was wondering if you could tell me where I was?" He added.

"Uh- STAR labs? You know. The place that kind of blew up the city?" The man responded.

"Yea- no. I have no idea what you're talking abou- what city is this exactly?" Peter asked.

"Central City. Hey- do you need me to call someone for you? Maybe your mom?"

"My mom's dead." Peter shook his head. "What's your name?" He asked again, stopping the man from sympathizing him.

"Oh! Cisco!" He nodded his head upward as he grabbed a lollipop and offered one to Peter to which he gladly accepted.

"Nice to meet you, Cisco. So, uhm. What state is Central City in?" Peter asked again. Instead of his confusion dying down, it only grew by the second.

"Missouri. Are you sure you're alright? Where did you even come from?" Cisco asked the teen, growing more concerned with each question he answered.

"Missouri? How the hell did I get all the way to Missouri?" The spiderling spoke to himself, taking his phone out of his pocket.

As Peter checked his phone, Cisco called Caitlyn for back up. This kid obviously wasn't alright so a checkup wouldn't hurt.

"My phone isn't working. I don't think it's on the right frequency for whatever reason. Maybe the blast did it?" Peter said, the last sentence being under his breath.

"Frequency? Oh." Cisco said, realization spreading across his face.

"What? Do you know what's going on?" Parker questioned, returning his back into his pocket.

"Yea. I think. Let me make a phone call real quick." Cisco left the room, leaving Peter to look at all the tech in the room.

Then, out of nowhere. A man appeared. Seriously where did he come from?

"Uh-" Peter started, looking around questioningly, trying to figure out how he just seemingly appeared out of thin air.

"Hey! Peter, right?" The man asked.

"Yea..? How did you.." He trailed off.

"Oh. I'll explain later. My name's Barry." The man introduced himself, reaching his hand out to shake. To which Peter did.

"Alright. Well- uhm.. can you help me find my way back home?" Peter asked, looking around the large room again.

Before Barry could answer, a lady with soft brown wavy hair walked into the room, followed by Cisco.

"Okay. Peter this is Dr. Caitlyn Snow. She's going to give you a quick checkup while i ask you a few questions about where you came from. Is that okay?" Cisco asked.

Peter nodded, "Yea. I could do that." He followed Caitlyn, Cisco, and Barry into a different room with a bunch of doctor tech. He recognized quite a few of the tools from his countless visits to the med bay in the tower back in New York.

"Have a seat in the bed and I'm going to give you a normal checkup just to make sure you're alright." Caitlyn informs the teenager.

Peter nods and sits onto the bed as Cisco and Barry stands a bit away from the two with a notebook and pen in hand.

As Caitlyn starts a normal routine checkup, Cisco asks his first question.

"What was the last thing you remember before getting here?"

Peter thinks for a bit, wondering if he should tell these strangers that he was blasted by a canon and teleported across the map.

Before he makes his decision, Caitlyn speaks again, "Peter. Were you aware of your two broken ribs?" She asks, worried for the kid.

"Oh- uh.. no?" He grimaces. He had been too caught up in the fact that he was in a completely different part of the US to realize that it was kind of hard for him to breathe.

"Why do you have broken ribs, kid?" Barry asked, concern lacing his voice.

Peter sighed before deciding to tell a least a bit of the truth. It would be easier this way anyways, and his instinct told him that these people were trustworthy.

"Okay so do you know the Avengers?" The spiderling asked.

"The who?" Cisco asked in confusion.

"The Avengers? The heroes that have saved the world dozens of times? You know like Ironman? Captain America? The Black Widow? Those guys?" Peter tried clarifying. To which Barry shook his head.

"Okay, kid. I know the problem. Do you believe in the multiverse?" Cisco asks.

"You mean like there being billions of billions of earths in the universe? I've thought about it and theorized with my mentor about it a couple of times." The adolescent answers.

Cisco nods, "Well, it's definitely real. And you're definitely not from this earth." He explains.

Peter's jaw drops.

"Seriously? That's so cool! Mr. Stark is not gonna believe this! Nor is Ned. Oh my gosh Ned will freak! Wait. How do I get home then?" Peter quickly calms down from his excitement once he realizes that he has no freaking idea how he'll get back to his earth.

"Don't worry, Peter. Once we get more information on your home, we'll be able to send you back. Now, can you tell me more about the Avengers?"

\\Time Skip//

Once Cisco is done questioning Peter, he goes to do research to find which earth he was from.

"So, you wanna tell me why you have those broken ribs now?" Barry asks, after Caitlyn has bandaged the kid up and told him to lay down.

Peter sighs, "Uh well you know how I told you guys about the Avengers? Well I guess I'm sort of an honorary member of them. I show up whenever they need help or want to train and practice their skills with me. We were in the middle of a fight with these robots who had a crap ton of weapons, but one in particular was extremely dangerous, so we were trying to keep an eye out for it. I finally found the weapon but a robot had it, so it started chasing me with it. Then it started shooting at me and when it finally hit me, I ended up here." Peter explains to the speedster.

Barry nods, "So, you have powers?" He asks after a few seconds.

"Yea. I got bit by a radioactive spider at a field trip at the end of 9th grade, so I basically have spider powers. I can climb walls, I have enhanced senses, I can run faster and longer, I have super strength, enhanced healing, I have a sixth sense for when something bad's about to happen. I also built webs for me to swing on even though i produce my own from my wrists. My natural ones are really thin though so it's easy to break." He explains, Barry looks shocked at all of the things the teenager can do just from a spider bite. Radioactive or not, that's still a lot of abilities.

"That's awesome. I have powers too, if you couldn't tell from earlier. I'm basically really fast. I can run fast, read fast, heal fast, I can even vibrate so fast I can phase through solid surface. Also, because I got my powers from being struck by lightning, I'm able to throw it." Barry told.

"Woah. That's really cool. I have a friend that can run really fast. He can't throw lightning or anything like that but he leaves this bluish grey trail when he runs." Peter gushes.

Barry smiles at the teen's excitement.

"Alright. I've narrowed it down to five earths that have the Avengers in it who've just had a fight with robots within the last 24 hours." Cisco comes in, typing on his tablet with a lollipop hanging from his mouth.

"Here. You can check and see which one is the most familiar to you." He hands Peter the tablet and lets hit look through the five different earths.

Right away, he knows the first one isn't right. Hawkeye is a woman in that one, so unless Clint needed to tell Peter something, he could cross that one out.

Next, in the second one, the hulk is a bright orange color instead of green. It makes Peter snicker a bit, but he eventually moves to the next one.

That one wasn't right either. Loki and Thor's roles were switched in the first battle with the original six avengers. Even though Loki is semi-good now, he definitely wasn't back then.

The fourth one looks pretty good, so he moves to the fifth one just in case. But, the fifth one Steve Rogers was Ironman and Tony Stark was Captain America.

Giving the tablet back, Peter spoke, "The fourth one is the best choice."

Cisco nodded and raised his fist up, a portal opened in front of the trio and Peter stood up in astonishment.

"Woah.." He spoke, eyes wide.

"Alright. Let's get you back home, kid."

\\Universe swap//

"What do you mean you can't find him?!" Tony yells, face red from all of the emotions swarming his mind.

"We've looked everywhere, Tony. We don't know where he went." Scott replied, voice way calmer than Tony's, whose put his face in his hands, holding back tears. He's already cried four times since Peter's been gone and it's only been 2 hours.

Before anyone could speak again, a portal opened in front of the tv, startling everyone in the room.

Then, out stepped Barry Allen, Cisco Ramon, and.. Peter Parker.

"Kid.." Tony whispered as Peter walked over to him.

The teen opened his mouth to speak, but was cut off by the billionaire pulling him into a bone crushing hug.

"Don't ever do that again. Matter of fact, if you disappear  like that again, you're grounded for the rest if your life. You understand me, mister?" Tony half joked.

Peter laughed and nodded his head, letting a few tears fall from his eyes as he was being held by his mentor.

And if Tony was crying too, nobody dare mentioned it.
