The Flash: The Fastest Man Alive (Male Reader Insert)

9.3 Flash of Three Worlds

Barry: You're Barry Allen from another Earth?

Barry-90: Earth-90, to be exact. 

Cisco: So, wait, is Jay your doppelganger or is Barry?

Jay: Both. 

Jay walked over to his counterpart. The red devil-suited Flash was panting and nodding his head.

Jay: What's the word on the stability of other worlds?

Barry-90: Earth-2 was the first to perish in the test fire of a new weapon. It was followed suit by Earth-X, 19, 789, 66, and 38.

Jay: Shit. Any word on the Pillars?

Barry-90 nodded his head.

Barry-90: I was able to contact three of them. They're in waiting for us. I was personally able to meet with one from Earth-1992. 

Jay: Good to here. Hopefully with all of them together, we can restabilize the multiverse before more Earths collapse. We just had our own run in with the Anti-Monitor. He was using some type of bomb. Thankfully, our quick Pillar here was quite skilled and took charge during the debacle.

The two turned to face Y/N. The young man stepped forward towards the two men. He looked between them in curiosity, still taking in the fact that yet another Flash was in the room with them. Barry-90 looked at the Flash of Earth-62612. A light grin appeared on his face, almost like a look of relief.

Barry-90: It's a pleasure to see you again, Y/N, especially a version that seems equal to me. 

Y/N: Uh... thanks.

Y/N was still taking in the strange man. His mind was accepting it, but also refusing to see it as right. It was a Flash who looked like Henry Allen but bore the name of Barry Allen. It was trippy for him to take in. Y/N shook himself out of it and went back to what the Flash had said about seeing him "again".

Y/N: I'm sorry. Have we met before?

Barry-90: No, we have not. But I have met some of your other selves and am well acquainted with my version of you.

Y/N looked at him curiously. He had a doppelganger on Earth-90?

Barry-90: On my Earth, you were a powerful sorcerer. A true warrior and hero, fitting of the name. We fought alongside one another, sometimes even acting as partners. You were a great team player... and a good friend.

Barry-90's face dropped as he said the last part. His mind went back to how it all had changed. His entire life, transformed in an instant. Barry-90 looked back up at Y/N. A small portion of his grin returned as he gazed upon a face that belonged to a different man, but one all too familiar to him.

Barry-90: We had a name for you on my world. Doctor Fate. You came to me one day talking about how you'd found a way to visit other Earths and had encounters with some of your own doppelgangers. Seeing the varying differences in your own counterparts compared to others', you theorized the existence of Cognate Pillars, beings who embody the very soul of the multiverse itself. Your theory was further confirmed by an encounter you had with a being known as the Spectre. That ended up being one of our last conversations we had with one another. You fought till the last breath, determined to see everything set right again.

Earth-90

Barry-90: (narrating) We became one of many worlds tested by the Monitor to search for his champions. He unleashed the Book of Destiny on our Earth, altering its history and causing untold destruction. In the end, we sacrificed everything to stop him and he still won.
