Speed Force

"The Speed...Nora here...is omnipotent, omnipresent, and omniscient."

- Chester on the Speed Force

The Speed Force was a source of energy that provided speedsters with their powers.

Creation
The Speed Force itself was created at the beginning of time and will never die as it is an infinite amount of energy. During the history of the Multiverse, Speed Force has given countless Meta-Humans with its energy and turned them into Speedsters under different circumstances.

"Death"
During the Crisis. The Spectre gave Barry Allen a boost to enter the Speed Force in order to travel to the Dawn of Time. After the Multiverse got restored, Wally West felt something wrong and returned to Central City to talk to Barry, only to know that he suffered from a few "hiccups" while accessing his speed. Later, they entered the Speed Force to talk to them and realize that the Spectre energy unbalanced the nature of the Speed Force and caused its "death". After the death, Barry and the other speedsters started to lose their speed which caused Barry to begin to build an artificial Speed Force.

"Resurrection"
Despite Barry's creation of the Artificial Speed Force, it inhibited his emotions and hurt Iris. This caused Barry to regain his emotions and destroyed the ASF with a lightning bolt. However, Barry required his speed to fight Mirror Monarch and was able to restart the Speed Force with the energy residue in Iris' body after years of contact with Barry's super speed. Unbeknownst to Team Flash, the reactivation created the Strength, Sage and Still Force.

Asking for Help
After being allegedly attacked by the other Forces, the Speed Force was severely injured and teleported to S.T.A.R. Labs as Nora Allen, seeking Barry's protection. The team then brought her to the medical lab and treated her injuries. However, the Speed Force being weak caused Barry to have a slower speed and forced him to enter the Cryo Pod.

Under protection of Barry, "Nora" worked with him as a crime scene investigator and attempted to help him with random bursts of energy. This enraged Barry and he told her to leave. Iris then approached "Nora" and talked to her about how Barry felt uncomfortable with the Speed Force as his mother. The Speed Force later reconciled with Barry and agreed to work together to protect her.

Going Rogue
"I need your powers to defeat her, and you promised. And now you're breaking that promise. And I know why. You may be his lightning rod...but I'm the lightning."

- "Nora" attacks Iris

After frightening Alexa Rivera, "Nora" attempted to kill Iris in order to gain Barry's support. Barry leaped in front of the lightning and counteracted it with his own bolt. "Nora" stopped the lightning bolt midair and absorbed into her own, eventually blasting Alexa with double lightning bolts and killing her.

Yellow and Orange
Yellow lightning is seen on Speedsters who recently gained a connection to the Speed Force and their power has not yet manifested. However, Speedsters wearing a reflective armors will emit white lightning. As the speedsters gain more power and a stronger connection to the Speed Force, their lightning will be manifested into orange. The following are the speedsters who emit yellow and orange lightning:

Red

 * For further information, see Negative Speed Force.

Red lightning is seen on Speedsters with a connection to the Negative Speed Force. It is also seen on Hunter Zolomon who became Black Flash after being taken by Time Wraiths. Edward Clariss also had red lightning due to an unknown reason. The following are the speedsters who emit red lightning:
 * Eobard Thawne

Blue
Blue lightning is seen on speedsters who gained an artificial connection to the Speed Force, mostly the use of Velocity Serums. After mixing with Tachyons, the blue lightning will turn into white and will occasionally emit blue lightning. The following are the speedsters who emit blue lightning:

White
White lightning was seen on speedsters who used Velocity Serums and Tachyons to increase their speed. White lightning is also seen on speedsters who uses reflective armors. However, white lightning was never recorded in history books and in the database of Flash Museum. Later, it was shown that those who took the Velocity Serums will retain their white lightning when they were given organic speed. The following are the speedsters who emit white lightning:
 * Godspeed Clones
 * August Heart
 * Godspeed Clones
 * August Heart
 * August Heart

Purple
Purple lightning was seen on Accelerated Man and briefly Iris West-Allen after Matthew Kim transferred Barry's powers to her. There are currently no explanation for why purple lightning was created while running. The following are the speedsters who emit purple lightning:
 * Nora West-Allen
 * Nora West-Allen
 * Nora West-Allen
 * Nora West-Allen

Yellow and Purple
Yellow and purple lightning was only seen on Nora West-Allen. It is presumed that the mixed color lightning is caused by genetics as her mother (powers briefly transferred to her) and father emit purple and yellow lightning respectively.

Red and Purple

 * For further information, see Negative Speed Force.

Red and purple lightning was seen when Nora gained a connection to the Negative Speed Force.

White and Yellow
White and yellow lightning was seen in the Speed Force when a physical form of Speed Force tried to regain Barry's body and save him.

Black
Black lightning was seen when a speedster got infected by Ramsey Rosso's blood.

Green
Green lightning was seen after Speed Force was unbalanced by Spectre energy.

Eye
Having connection to the Speed Force allows the speedsters to have lightning flicker or glow in their eyes. The color of the eye is nearly identical as their lightning color with an exception of Hunter Zolomon as he has black glowing eyes and blue lightning.

Physical Powers

 * Electrokinesis: When the Speed Force appears in its physical form, it is able to produce lightning bolts of different colors.
 * Electricity Absorption: The Speed Force was able to absorb the lightning bolt thrown by Barry Allen and redirect it at Alexa Rivera.
 * Accelerated Perception: As a presence living in the past, present and the future, the Speed Force is able to perceive mortal activities easily and respond to them faster than the speed of light.
 * Superhuman Reflexes: The Speed Force was able to react to Barry Allen's attacks and redirect them.
 * Superhuman Durability: The Speed Force cannot be killed by mortal attacks, with its physical body being strong enough to withstand them.
 * Superhuman Stamina: Without the need to eat or drink, the Speed Force is able to run and move for a long period of time without showing the signs of exhaustion.
 * Superhuman Speed: As the energy source of countless speedsters, the Speed Force itself has the ability to run at superhuman speed.
 * Time Travel: The Speed Force is able to teleport to different time periods and meet those with connection to it across time.
 * Inter-Dimensional Travel: The Speed Force is able to teleport to different universes in the Multiverse.
 * Energy Manipulation: As the energy source of speedsters, the Speed Force is able to reabsorb the superhuman speed of certain individuals, leaving them harmless.
 * Memory Manipulation: The Speed Force is able to remove the memories of speedsters.

Speedsters Powers

 * Accelerated Healing Factor: Speedsters are able to heal from extreme injuries in a short period of time due to their superhuman metabolism.
 * Aerokinesis: Speedsters are able to move their bodies at superhuman speed and create vortexes, cyclones, tornadoes and vacuums of air. This allow them to propel their opponents away.
 * Bodily Vibration: By vibrating at superhuman speed, speedsters are able to create visual and audio illusions, such as voice modulation, invisibility and masking their faces. Additionally, by vibrating at the same frequency of air, speedsters are able to "phase" through solid objects.
 * Speed Force Siphoning: Speedsters are able to create sonic booms simply vibrating at a high speed, allowing them to siphon speed off other speedsters and absorb their energy.
 * Electrokinesis: Speedsters produces small lightning trails behind them when they run at superhuman speed. The color of the lightning trails varies and can be briefly altered when they gain a connection to the Negative Speed Force or inject themselves with Velocity Serums.
 * Speed Force Aura: Speedsters are protected by an aura of invisible energy, protecting them from burning due to extreme friction and from gravitational forces. The aura can also be expanded and withstand the gravitational pull of a black hole, while protecting its users from being injured or destroyed. The aura was also shown to be able to protect those being carried by speedsters, protecting them from the extreme friction produced from superhuman speed.
 * Speed Force Sharing: Speedsters are able to share their superhuman speed through physical contact and allow them to be stabilized from certain conditions. Experienced speedsters can also bring non-speedsters into a phenomenon known as Flashtime, with a limited time as non-speedsters are unable to survive long at that speed.
 * Electricity Absorption: Speedsters are able to charge themselves with exterior energy sources, supercharging their bodies and giving a boost in speed.
 * Electrical Constructs: Experienced speedsters are able to channel the lightning produced from their bodies and shape it into different objects, with the example of tulip flowers, lassos and shurikens.
 * Accelerated Perception: Speedsters are able to perceive actions and words that appeared for a brief moment in time. In order for them to communicate with humans, they are able to shift the perception level according to their will.
 * Superhuman Senses: Speedsters are able to have enhanced senses and able to hear sounds even after exceeding the speed of sound, which no sounds can be heard normally.
 * Superhuman Momentum: Speedsters are able to generate and withstand extreme kinetic energy. They are also able to stop completely even running at the speed of light.
 * Seismokinesis: By running back and forth on a particular object or construction, speedsters are able to create a small earthquake, capable of destroying a bridge.
 * Superhuman Strength: While running at superhuman speed, speedsters are able to carry heavy objects and even drag an individual around easily.
 * Superhuman Durability: Speedsters are able to withstand extreme forces and attacks with little to no injuries. However, they are still vulnerable to bullets and swords, which are able to pierce their skins and even kill them if they do not respond to attacks quickly.
 * Superhuman Agility: Speedsters are able to balance off unstable constructs while running at superhuman speed, allowing them to easily maneuver at obstacles.
 * Superhuman Reflexes: Speedsters are able to respond to attacks quickly, including a speeding bullet and physical contacts.
 * Superhuman Stamina: Speedsters are able to run for an extended period of time with no signs of exhaustion.
 * Superhuman Speed: Speedsters are able to run at superhuman speed and easily exceed the speed of light through months of training. The superhuman speed grants them multiple additional powers.
 * Speed Mirage: By running back and forth between two places, speedsters are able to create a mirage that there are two or more individuals standing still. However, they look less realistic when there are more mirages being created.
 * Time Travel: By running faster than the speed of light, speedsters are able to break the space-time barrier and open a portal to the Speed Force, allowing them to run across time with flashes of images passing through them in the vortex.
 * Temporal Regression: Speedsters are able reverse a short period of time without affecting themselves and retain the memories in the process,
 * Time Remnants Construct: Skilled users are able to create a "clone" of themselves that retains their memories and personalities with their own minds. However, their personalities slowly diverge from the "prime" version through time. Time Remnants also retains all abilities a speedster does and even become stronger than their "prime" version. Despite their convenience in battles, Time Remnants are required to be killed in order to preserve the timeline integrity.
 * Time Travel Awareness: Speedsters are able to sense other speedsters travelling across time through the Speed Force.
 * Clones Creation: Certain speedsters are able to create a series of clones without the ability to talk in human languages. The clones can be reabsorbed to their creators in order to generate a boost in their speed.

Weaknesses

 * Antimatter: The Speed Force is unable to let speedsters run past a point in time that was destroyed by Antimatter.
 * Cold Temperatures: Speedsters' superhuman speed are hindered when they are exposed to cold environment.
 * Gravity: Without gravity, speedsters are unable to use their superhuman speed.
 * Hyper-Metabolism: Speedsters have high rate of metabolism, requiring them to eat a large amount of food in order to maintain their peak physical performance. Their hyper-metabolism is also against any painkillers, drugs and alcohol except for those created specifically for speedsters.
 * Nanites: Speedsters' abilities are temporarily negated by nanites. However, it was shown that vibrating at the frequency of air allows the nanites to exit their bodies, regaining their powers immediately.
 * Negative Tachyons: As opposed to Positive Tachyons, speedsters being injected with Negative Tachyons reduces their speed and prevents them from entering the Speed Force.
 * Speedster Weapon: A series of weapons were created in order to fight speedsters, the weapons are able to stop speedsters from running and injure them for a short period of time.
 * Vibers Ergokinesis: The multiversal energy channeled by Vibers are capable of stopping speedsters from running further.
 * Entropy Trap: The Entropy Trap is able to stop all motion in time and stop speedsters from moving when they enter the bubble.
 * Kinetic Energy Absorption: When facing opponents with the ability to absorb kinetic energy, speedsters are unable to run at all or even move due to the lack of kinetic energy.
 * Imbalance in Energy: When Barry Allen was given a boost from the Spectre, the Speed Force was flooded with "Spectre Energy" and slowly became weaker, causing small "hiccups" in speedsters. The Speed Force later died due to the imbalance of energy and reborn when Iris West-Allen sparkled the residue Speed Force energy back to the Speed Force itself.
 * Forces of Nature: As a Force of Nature itself, the Speed Force is vulnerable to other forces and can be injured by them.
 * Nuclear Explosion: Despite speedsters' ability to outrun a nuclear explosion, an explosion happening in the Speed Force could annhialte the entire force itself, causing speedsters across space and time to lose their powers instantly.
