Negative Speed Force

The **Negative Speed Force** is an extra-dimensional energy source that was created by Eobard Thawne when he attempted to become a speedster.

## Overview

The Negative Speed Force allows all speedsters access to their main ability super speed as well as their derived abilities such as time travel.

## History

After getting his powers, Eobard Thawne wanted more power. So, he used his hatred for The Flash to create his own variation of the Speed Force, calling it the "Negative Speed Force". With the Negative Speed Force, Thawne was able to time travel without the Flash knowing his presence in the timeline.

## Physical manifestations

### Lightning coloration

* **Red:** Red lightning is typically the result of a speedster having a connection to the Negative Speed Force, which Eobard Thawne created at some point after recreating the accident that gave the Flash his powers. Red lightning is seen in Thawne himself.
* **Black:** After Thawne was slowly being erased from existence, he emitted black lightning with a white aura.

## Powers and abilities

### Powers

#### Speedster powers

*The only powers listed below are the ones that differ between the Negative Speed Force and the Speed Force. For all of the powers that a speedster can have, see Speedster powers.*
The Negative Speed Force, like the Speed Force, enhances all movement, momentum, and force exerting capabilities of its user, down to a microscopic level, as well as giving the user conscious control over it. This enhances overall acceleration, agility, reflexes, coordination, balance, and reaction time to inhuman levels. In addition, the body becomes conditioned beyond human potential, allowing them to handle extreme physical exertion and performance, which is also enhanced.
* **Time travel:** Users of the Negative Speed Force can travel through time like users of the Speed Force. However, since they use the Negative Speed Force to time travel, users of the Negative Speed Force cannot be detected by users of the Speed Force.
* **Speed Force negation:** Users of the Negative Speed Force can temporarily cancel out another speedster's speed by hitting them with negative lightning.

### Weaknesses

#### Speedster weaknesses

*The only weaknesses listed below are the ones that differ between the Negative Speed Force and the Speed Force. For all of the weaknesses that a speedster can have, see Speedster weaknesses.*
Like with the Speed Force, speedsters may show one or more weaknesses despite their connection to the Negative Speed Force. Whether this hints towards inherent limitations of the Negative Speed Force itself or just to limitations of its users' control over their connection to it, is not known for certain, but the latter seems more likely.
