Warning

Barry Allen was desperate.

Thawne had come out of nowhere when the red skies had appeared. He seemed to have the same yellow suit that haunted Barry's nightmares quite often. His phasing face, his glowing eyes, his red lightning. Everything was the same.

Barry had no time to react before he was punched in the gut and he flew back from the impact, crashing into a barren field. Groaning as his head thundered painfully from the impact, he held his ring out and hurriedly put his suit on.

"Come on Barry. Lets see who is the fastest."

Barry's eyes flashed with orange lightning and he charged at Reverse-flash, the latter smirking and running opposite from Flash. The duo ran across Central City, the CCPD, the Star Labs, The CCPN. Everywhere.

Finally, Reverse flash turned stopped and Barry stopped behind him shortly, wondering what he was planning.

"Why are you back here Thawne?" Barry screamed. His hatred for Thawne had grown significantly when he had realised that Thawne had manipulated his daughter in helping him escape and making the girl fade from existence.

Thawne turned around, taking his cowl off, his face stopping to phase and Barry saw the face of his mentor, Harrison Wells. "I think you know very well why I am here."

"The crisis," Barry muttered to himself. Harrison- Thawne- nodded with a wide smile, "Yes Barry. It is indeed here. Multiple earths have been devoured by the Antimatter and this earth will be next. This earth is the prime earth, being in the middle of the multiverse, and its destruction will lead to destruction of other earths."

"The domino effect," Cisco's voice spoke from Barry's earpiece. Thawne smirked evilly again and said, "What are you going to do now Barry? You know that this earth will fade into nothingness if you don't die, and if you die, I will win. You can't let that happen, can you Barry?"

"Don't listen to him Barry. He is just trying to influence you into making the wrong move," Iris' voice said, soon followed by Cisco's agreement and his promise to solve how to defeat Reverse Flash and save the earth. Barry just glared at his former mentor before a vision came to his mind.

It was the Speed force when he had gone to rescue Wally, You must free yourself. He sighed and whispered in the earpiece, "I am sorry guys but I need to do this alone. I love you guys and you Iris."

He could hear breathing and someone was about to say something, probably to change his mind but he switched it off and threw it to the ground. Thawne laughed out loud and put on his cowl, looking at the sky. A lightning bolt crashed next to Thawne, making the speedster wince before he made a challenging wave towards Barry and sprinted out.

The Flash ran after him, trying to catch up to him and stop him and then to save this earth. He jogged, no pun intended, his brain, trying to get some ideas.

The Speed Force prison? No, if I do that, then Speed Force would know I escaped and I don't want to know what the consequences for that would be.

Before he noticed, Thawne stopped and ran towards Barry. All Barry felt was pain in his face, soon followed by pain erupting in his back. He groaned as he held his broken nose and struggled to stand up. Before he could do that though, red lightning surrounded him, punching and kicking him, not letting him tap into the Speed Force.

Finally, he stopped and Barry crashed to the ground, blood pouring out of his wounds and Thawne grabbed the front of his suit and pulled him close till they were breathing each others breath and said, coldly, "This isn't over. Anti-Monitor is coming, sooner than you expect. Better prepare yourself for it, because the next time we meet in crisis, I will not hold back."

Barry tried to reply but Reverse Flash carried him as he ran and threw him from a building and for good measures, pushed him away from himself and ran away, bright red lightning trailing after him. The Flash tried to tap into Speed Force but with no friction to run on, he couldn't get his speed to work and soon crashed on a roof of a car, making the roof crumble inside.

Barry tried to move but he couldn't and after a few seconds, faded into unconsciousness, words echoing in his mind, Better prepare yourself for it.

A/N: My first Flash fanfic and probably my only one. I am a really big fan of Flash and thought about this idea when I was watching all the episodes of Flash again. This is a three-shot and only featuring Barry Allen and Eobard Thawne (both Thawne and Wells)
