With a new villain arising in Central City, can he fight the darkness long enough to save the day or will his newfound bloodlust destroy everything he loves? Takes place season 3. Cisco's mad at Barry, and hasn't forgiven him. Invasion never happened. Caitlin is not Killer Frost.

Due to him losing his speed, Barry has been obsessive with looking for other alternatives to get his speed back. The one thing he never thought of was the negative speedforce. Even though he hates Eobard Thawne, he turns to him, wanting to know how to get his speed back with the negative speedforce. But it will come at a heavy price. A price that Barry is willing to pay. But, what he didn't account for and what he doesn't realise is that the effects of the negative speedforce changes a person.
