The Flash is owned by The CW. Just a warning: Future Barry is going to be very dark in this fic. In Barry's future, he was betrayed by Julian, Caitlin, HR, and Iris. He also comes from a war ridden future. Also, Future Barry has lost his mind. With that in mind, enjoy the fic!
Central City was in shambles. There was no right, nor wrong, just chaos. What used to be a city was just ruins now. Buildings were in pieces, and what was standing had long since gone out of business.
Doors were bashed in, windows were shattered, buildings were empty, lights were absent. He continued walking until he spotted a newspaper in the long-abandoned town once known as Central City.
"Central City closes its doors after the uprising." It reads. The uprising was an event that happened in 2030, when Barry's blood was stolen. The blood was fashioned into a street drug called The Speedster's Paradise, which could turn anyone into a speedster once injected. The new speedsters went mad with power, and that's when the uprising happened. Metahumans and humans were at war with each other, which eventually leads to the destruction of Central City.
Star Labs was in shambles, rubble covering the outside. The right of the building didn't have walls anymore, so anyone could walk in. Barry could hear the pop of electricity as the building ran on emergency power. Barry had kept the building running as much as he could with what was left of the building. Barry hadn't seen the team since the uprising three years ago.
Julian had snapped the day of the uprising, joining Killer Frost as Alchemy. The two had joined the Metahuman war, and that was the last time that Barry saw them. Cisco had moved to Earth-2, and Barry hasn't seen him since. HR had joined the humans in the war, and Wally had moved to Star City after the relocation project, leaving Barry completely alone. Fuck, how long has he been in Central City?
Barry had lost count long ago. Barry's reflection was looking back at him on the monitors. Barry's skin was a lot paler now that he couldn't eat as much. Barry was living off rations now, as he was the only person still left in Central City. Most of the food he eats now is in a can, and what he can't find in a can, he grows. When was the last time he wasn't eating expired food? Barry couldn't remember.
Barry hadn't shaved in months. Why would he, when there was no one to look presentable for? Iris had joined the humans in the war, and had tried to kill him. Like his friends, she had betrayed him. Barry's hair was past his shoulders now, but it wasn't healthy. Barry didn't bathe anymore either, as food and water was his main concern. Slowly, Barry opens the cans, deciding to eat two whole cans this time. When Barry ate the two cans, he slowly feels his energy return. Lightning appears in Barry's eyes, as he had eaten enough that he could use his powers, at least for now.
Barry's forty-fourth birthday was yesterday, but thanks to the decelerating aging that comes with the speed force, his physical appearance matches that of someone in their twenties. Suddenly, a thought occurred to Barry. Now that he had enough energy to use his speed, he could go back to 2017 and prevent The Speedster's Paradise from ever being created in the first place.
With that, Barry starts running, and soon enough he finds himself in the speed force. Eventually he gets to 2017, and that's when he exits the speed force. When Barry finally got out of the speed force, the sight of Central City in pristine condition from before the uprising made him want to cry. Barry couldn't let himself cry though, he had to get to Star Labs first. Without a second thought, he starts running, arriving at Star Labs a minute later.
"What the?" Cisco asks, staring at Barry. This Barry was older, paler, and if Cisco didn't know better, he'd say that he was sick.
"Allen?" Julian asks with confusion.
"I'm so glad I made…" Barry passed out after that, as he hadn't been able to find enough food in what was left of his version of Central City.
"Shit! Allen!" Julian shrieks, catching Older Barry before his head hit the ground. It was then that Past Barry raced in.
"How? What?" He stammered, staring at his future self.
"Your guess is as good as mine." Julian comments.
"What's wrong with him?" Barry asks.
"I don't know, let's hook him up to the monitors." Caitlin suggests, hooking older Barry to the monitors.
"Caitlin, look at the glucose levels." HR sighs.
"Jesus, he's barely eaten anything! Why?" Barry shrieks. It was then that Caitlin hooked him up to IVS and a feeding tube.
"He's obviously from the future. Question is: how far in the future is he from?" Julian asks. It was about three hours later when Older Barry slowly opened his eyes.
"Welcome back! What should we call you?" HR smiles. Older Barry blinks in confusion for a second. Oh, right, he had gone back in time to 2017.
"Call me Bar." He answers. As Bar stares at the Team, he can't help but see them as the people that had betrayed him.
"Bar? Are you alright?" Cisco asks with concern.
"I'm fine." Bar snaps, still feeling anger at his friends.
"We did something in the future, didn't we?" HR asks.
"I don't want to talk about it." Bar sighs. He knows he shouldn't be mad at them, they aren't the ones that betrayed him, but Bar can't help it. He still remembers the betrayal, and it had been them.
It was then that he races down to the time vault, locking it from the inside.
"Gideon, show me the timeline from the year 2030." He demands.
"Certainly." Gideon greets, showing Barry the future. Barry sighs when he realizes that the future hasn't changed. The uprising still happens.
"Thank you, Gideon. Please go back to the 2024 article." Barry orders.
"Certainly Mr. Allen." Gideon greats, changing it back to the article from when Barry had supposedly vanished. After that, he unlocks the time vault as he walks back to the medical bay of Star Labs.
"Bar, I know you don't want to talk about it, but I can tell that we hurt you. Please, tell us what we did so we can make it up to you!" Julian pleads.
"Nothing you can do will ever make it up to me." Bar growls.
