Damien: I dimension hop remember?

Soph: Seagull.

Damien: Language.

Soph: Whatever. It's Marvel Avengers vs. DC Flash, why not Comic Wars?

Damien: I dunno. It sounds like Star Wars.

Soph: So?

Damien: People now know you're a Star Wars fangirl...

Soph: ._. Screw you.

Prologue: Telephones & Plans

It was a beautiful summer evening in Central City. Everyone was outside, enjoying the nice, warm weather and no one thought of staying indoors... except for Dr. Harrison Wells, who was on the phone.

"Hey, I thought of this cool idea. Kinda impossible, but, you know, that's my thing." said Tony Stark over the phone.

"And what is this impossible idea?" asked Dr. Wells.

"Please don't laugh when I say this, but... it's a time machine." He paused, expecting a laugh or some sort of incredulous response but Harrison kept quiet. Tony half-laughed, "Crazy, right? Yeah, I know. I almost didn't believe it myself until I looked into it and realized it was actually possible."

"No, no. I believe you, Tony. Only, have you figured out how?"

"Erm... No, not really. I was thinking of having Pym's, Vision's and Banner's help. Whaddya think?"

"Well... I am interested and very willing to help you."

Tony hesitated, "Sure... I suppose, I mean, you can help but I don't want the machine exploding."

This again, thought Wells, "Don't worry. I am not prone to making the same mistake twice."

"If you're so sure..." He paused and quickly added, "See you soon."

The call ended.

"Yes... See you soon, see you very soon." Wells thought aloud while looking at his Reverse-Flash suit. He was inside his secret time vault.

He turned and powered Gideon on, "Gideon, book me a flight for tomorrow. Destination: Manhattan."

Part 1: Friends & Betrayal

Dr. Wells didn't catch his plane. Being stuck in a wheelchair is bad, but having to pretend to be paralyzed is worse. One con about his slow wheelchair, it had made him lose his plane. Another thing he regretted: telling off one of the airport employees who offered to help guide him through the airport and find his gate.

Now, how am I supposed to make it to Manhattan? thought Wells. If I don't use my speed, I won't make it. No, no. I can't risk losing my speed, I might need it.

Wells looked at his watch and reluctantly came to a decision. He wheeled over to a deserted hallway and stood up from his chair. Luckily, Cisco had just modified it to be foldable, and Wells didn't pack any baggage except for his Reverse-Flash suit that was in a secret compartment inside the wheelchair along with a metal, pointed cable. He grabbed the chair, folded it up, and zoomed off, leaving his trail of red lightning. Next stop: Manhattan.

The Next Day

"Hey Caitlin, do you know where Dr. Wells is?" asked Barry.

"Oh, he said he was going to a lecture somewhere near the East Coast and wouldn't be back for a while." replied Caitlin.

"Seems like we have the whole lab to ourselves then." smiled Cisco.

Barry and Caitlin looked at Cisco with worried expressions. "What? I'm not going to make the lab explode." said Cisco.

Barry and Caitlin continued to stare at Cisco, "And I'm not going to make any weapons that a meta-human might steal."

"That's assuring." said Barry. There was a sudden PING that startled the team and Cisco went over to his computer to check what it was.

"Uh, Barry, seems like there's been a bank robbery near the police station." said Cisco.

"Already on my way." said Barry. He ran off, using his super speed to change into his Flash costume, and headed off to the location of the robbery.

Meanwhile

"This time machine of yours... How did you realize it was possible?" asked Wells.

Tony and Wells were taking a stroll along the docks. It was just past dawn and the sea breeze was refreshing.

"Well, I heard of this guy called the Flash. Apparently he has super speed, which I thought was a classic until I figured that if he could use super speed to turn back the clock, to be faster than time, I thought that if I could model the time machine after him, making speed its 'power core,' then if has a high chance of working. I ran a virtual test and the probability was that it had a 78% chance of working. Unfortunately, the remaining 22% meant the machine could explode." explained Tony.

"Seventy-eight percent chance... Now, Tony, I can assure you that that chance of working could become an 100% if you use the correct material because the structure itself would not be able to stand alone with the corresponding material, which in turn the machine would then have a very high chance of failing and could then open a singularity over the city." corrected Wells.

Tony suddenly stopped. Dr. Wells noticed and stopped as well only to turn his wheelchair around to face Tony.

"How do you know that, Harrison?" asked Tony.

"Seems like you've finally found your rival, Stark." replied Harrison bluntly.

"Seems like you're right." chuckled Tony. He walked over to an edge and sat down, legs dangling off the edge. Wells wheeled over to him but he still stayed a little behind.

It's time to act now. I do believe I won't get any other opportunity, besides, he is completely off-guard and vulnerable, thought Harrison. While Tony was distracted, staring off into the horizon, most likely meditating on his calculations, Harrison quietly opened a compartment in his wheelchair and took out a metal cable that had two pointed cylinders are either end. He stood up from his chair and untangled the cable.

"Tony." said Wells. Tony turned around only to be surprised at the sight of his paralyzed friend standing from his wheelchair holding a pointy cable.

In a split second, Wells thrust the cable at Tony, aiming for his chest, before his friend could react. Tony expected pain, horrible pain, but instead felt nothing. Instead he heard something break and looking down at his chest he saw his arc reactor had cracked and was losing its energy. Whatever Wells was doing hadn't worked but it was killing Tony.

Tony instantly threw a punch at his "friend" but Wells was fast, really fast. Tony's punch was in slow motion for Harrison so he easily dodged and was able to activate his lighting-shaped ring, transforming into Reverse-Flash. Time returned to normal and Tony found that he only punched air and that Harrison was a few meters away, wearing some kind of black and yellow suit.

"How...?" started Tony before he felt something hit him. Wells had used his super speed to hit Tony with such force that it threw him back. At this point, Tony was dying from his cracked arc reactor and was weak. He then landed unconscious and seemed to stop breathing.

After a few minutes, Wells knew Tony should be dead at that point so he unmasked himself, "That could have gone better." He was disappointed he had killed him, he needed him alive for his plans, but he saw no point in trying to make his DNA Transfer work on a dead person. He quickly gathered his items, left Tony there, and zoomed off. His plane to Central City wouldn't leave until the next day.

Later

"Tony!"

Stark jolted up and gasped for air. Around him stood Captain America, Thor, Hulk, Wasp, Hawkeye, and Black Widow. Ant-Man stood at some computers, most likely monitoring Tony's health. Stark was bewildered as to why the Avengers were around him.

"Thank God you're alive, Tony. You gave us quite the shock." said Cap with relief.

Like a blast to the face, all the memories of events that happened came to Tony. He realized that he virtually died in his battle with Wells.

"I'm gonna kill that guy." he mumbled under his breath.

Quickly, he recovered and explained what happened to his fellow Avengers. He went into some details but didn't mention that Wells was ever so fast, only that he was paralyzed but still managed to stand from his wheelchair.

"Hulk smash Wheelchair!" exclaimed Hulk.

"Yes, my beast friend. Wells will pay for his betrayal." Thor agreed with Hulk.

"Wait, so you befriended a man who lives on the other side of the country, is way too interested in time travel and yet that didn't seem suspicious at all?" asked Hawkeye.

"He was only interested in time travel yesterday afternoon when I mentioned it. Other than that, he seemed reasonable and he knew more science and engineering than me. And by science, I mean all kinds of science, from medical to quantum physics." replied Tony.

"What I don't understand is how Wells is paralyzed but he was able to use his legs perfectly. I mean, if it was fake paralysis then the doctors that treated him would have been able to tell. Unless he was like Deadpool and had incredible regeneration but I hardly can believe Wells would be a mutant." analyzed Hank.

Tony got up from his hospital bed, "JARVIS, prepare the Quinjet for departure." He winced from a small pain in his chest, "We leave tonight."

A/N: Wow... Welp, that was crazy. Also, I included the Prologue with the first chapter cuz its pretty short.

Damien: You could've just made two separate chapters and uploaded them both at once.

Soph: ._. *deep breath* The door's right there.

Damien: Fine *walks out* But I'll be back!

Soph: JUST LEAVE!
