Eobard Thawne (Earth-1: Pre-Crisis)

"My fate was to become your greatest enemy. I was never going to be The Flash. So I became the reverse of everything that you were. The more people you saved, the more you were loved, the more I had to take from you."

- Eobard Thawne to Barry Allen

Professor Eobard Thawne is a Metahuman time criminal from the twenty-second century who operates under the alias of the Reverse-Flash.

After the assassination of Nora Allen, Thawne was stranded in the twenty-first century with no means of returning to his home era. Thawne then took the identity of Dr. Harrison Wells and created S.T.A.R. Labs in order to move The Flash's creation earlier. Unfortunately, his identity as a villain was revealed when Cisco Ramon had a vision. Thawne then fought against Team Flash and was eventually erased out of existence when Eddie Thawne committed suicide.

Despite the effort Team Flash had done to erase Thawne from existence, the Flashpoint, where Barry Allen went back in time and saved his mother from being killed, caused Thawne's survival in the timeline. He then operated as a Time Remnant and restored the timeline. He later searched for the Spear of Destiny, a mystical artifact capable of rewriting reality, protecting Thawne from Black Flash's wraith. Unfortunately, Thawne's plan was ruined by the Legends of Tomorrow, who attracted Black Flash and killed Thawne, preventing any possible damages he might do to the timeline.

Due to Thawne's connection to the Negative Speed Force, his erasure from existence and death did not prevent his return from the dead. The third iteration of Thawne travelled to Earth-X and joined the New Reichsmen. He assisted the creation of inter-dimensional travelling technology for the New Reich. Now using the alias as Dark Flash, Thawne led the invasion of Earth-1, fighting his former enemies once more. Eventually, Thawne was allowed by Barry Allen to leave and was arrested. He was then imprisoned in Iron Heights Penitentiary and manipulated Nora West-Allen. Unbeknownst to her, Thawne was scheming his escape when he realized his powers were inhibited by Cicada's dagger, which he was informed of years prior when Barry and Nora went back in time and asked for his help. After Thawne's ultimate escape, he was preserved in the Negative Speed Force when the Crisis struck. He was later relocated on Earth-Prime as a series of Negative Tachyons, soon to replace his post-crisis counterpart.

Early Life
Eobard Thawne was born around 2151 into an affluent family of influential politicians, scientists and captains of industry, with him eventually becoming one off the most distinguished members as the forename, Eobard, would apparently suggest. When he was young, Eobard attended a grade school where he was taught astro-navigation.

Eobard later began to investigate his family history where he eventually found out about Eddie Thawne despite history having almost no record of his existence and he considered his ancestor to be a failure because of this.

In his adulthood, Eobard became a scientist and professor, who began to study the Speed Force in an attempt to unlock it's secrets. He also designed an Anti-Speedster Rifle at some point.

"I was obsessed with you. For so long, I wanted to be The Flash. I spent years figuring out how you came to be. Duplicated the reaction...and it worked. I became like you."

- Thawne to The Flash

He spent years pursuing the secrets of the Speed Force before eventually learning of The Flash who he began to idolise to the point where he was obsessed and wanted to be The Flash himself. After many more years of research, Eobard learned how The Flash gained his superpowers and built a machine to recreate the accident that gave him said powers which resulted in him becoming a speedster just like his idol.

The moment of his change in motives began when The Flash arrived in the future in pursuit of a case just as Thawne was about to present himself to the world. The Flash dazzled a crowd and saved them from danger, a role that Thawne would have taken if not for The Flash's sudden arrival. Thawne felt humiliated and began to lose his sanity, trying to become faster than the Scarlet Speedster.

He then learned how to use his powers to travel through time which he used to go back to an unknown point in the 21st century where he eventually learned that he was destined to become The Flash's arch-enemy under the alias of the "Reverse-Flash". He also either created or obtained the Reverse-Flash Suit which had the opposite colours to The Flash Suit.

This made him despise his former idol and he decided to make it his life's work to prove that he is the superior speedster, which only succeeded in fulfilling his destiny while he descended further into insanity. He also vowed that he would kill more people than The Flash had saved and that he would take more people from The Flash than those who he was loved by.

Eobard later created the Negative Speed Force in an attempt to be the exact opposite of The Flash in every way and also so he could time travel undetected. He also at some point obtained an artificial intelligence program called Gideon which was created by The Flash. He then began searching the timeline for eras when The Flash was active, eventually travelling back to the year of The Flash's origin which started their war across time.

Powers

 * Speed Force/Negative Speed Force Connection: Idolizing The Flash, Eobard Thawne recreated the accident that made him a speedster. Thawne then gained a connection to the Speed Force and unlocked powers that were deemed impossible. However, Thawne discovered that he was destined to be The Flash's archenemy. He then used his negative emotions and created the Negative Speed Force, where he retained his powers as a speedster without limitations.
 * Superhuman Speed: Thawne is able to run at superhuman speed and able to exceed the speed of light. The superhuman speed grants him multiple additional powers.
 * Speed Mirage: By running back and forth between two places, Thawne was able to create a mirage that there are two or more of him standing still, which he used in order to trick Team Flash and the CCPD.
 * Time Travel: By running faster than the speed of light, Thawne is able to break the space-time barrier and open a portal to the Speed Force/Negative Speed Force.
 * Time Remnants Construct: Thawne is able to create a "clone" of himself that retains his memories and personalities with their own minds.
 * Bodily Vibration: By vibrating at superhuman speed, Thawne is able to create visual and audio illusions, which he used to disguise his face and voice.
 * Intangibility: Thawne is able to "phase" through solid objects when he vibrates at the frequency of air.
 * Electrokinesis: Thawne produces red lightning trails behind him when he runs at superhuman speed.
 * Speed Force Aura: Thawne is protected by an aura of invisible energy, protecting him from burning due to extreme friction and from gravitational forces.
 * Accelerated Healing Factor: Thawne is able to heal from extreme injuries in a short period of time due to his superhuman metabolism.
 * Accelerated Perception: Thawne is able to perceive actions and words that appeared for a brief moment in time.
 * Superhuman Senses: Thawne is 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: Thawne is able to generate and withstand extreme kinetic energy. He is also able to stop completely even running at the speed of light.
 * Superhuman Strength: While running at superhuman speed, Thawne is able to break hard objects easily.
 * Superhuman Durability: Thawne is able to withstand extreme forces and attacks with little to no injuries. However, he is still vulnerable to bullets and swords, which are able to pierce his skins and even kill him.
 * Superhuman Agility: Thawne is able to balance off unstable constructs while running at superhuman speed, allowing him to easily maneuver at obstacles.
 * Superhuman Reflexes: Thawne is able to respond to attacks quickly, including a speeding bullet and physical contacts.

Abilities

 * Genius-level Intellect: As a scientist from the 22nd century, Thawne was taught and learnt advanced science. He was also a researcher on the Speed Force, which he was able to gain a connection to and create an alternate replica.
 * Master Physicist: Thawne is an expert in physics and was able to calculate the required information to assist The Flash and himself while operating in superhuman speed.
 * Master Engineer: Thawne is a skilled engineer and created multiple inventions to assist The Flash in battle.
 * Master Hand-to-Hand Combatant: Thawne was shown to be a skilled fighter, capable of fighting Barry Allen and multiple trained individuals easily.

Former Weaknesses

 * Anti-Speedster Rifles: Developed and designed by Thawne himself, the Speedster Weapon is a rifle that is capable of temporarily severing the connection of speedsters to the Speed Force/Negative Speed Force.
 * Irregular Gravity: Thawne is unable to use his powers of superhuman speed in locations with a relatively lower gravitational force than Earth. This was proven when he was unable to run or vibrate his body molecules on the Moon.
 * Cold Temperature: Like other speedsters, when exposed to cold temperature, Thawne's speed decreases drastically, leaving him vulnerable to attacks in the period of time.
 * Nanites: When shot with nanites created by Ray Palmer, Thawne temporarily loses his connection to the Speed Force/Negative Speed Force.
 * Positive Tachyons: Thawne's connection to the Negative Speed Force leaves traces of Negative Tachyons. As a result, their opposite counterparts, Positive Tachyons, are able to counteract Thawne's negative connection and gradually reduce his speed.
 * Cicada's Dagger: Cicada's dagger has the ability to dampen any Metahuman's powers. In 2049, Thawne was imprisoned with the dagger attached to his chest, negating his connection to the Negative Speed Force.

Former Equipment

 * Reverse-Flash Suit: As the Reverse-Flash, Thawne wore a yellow and red protective suit that was designed based on The Flash Suit.
 * Reverse-Flash Ring: The suit is stored in a golden-yellow ring for convenience.
 * Gideon: Gideon is an advanced A.I. that assisted Thawne for years before installing it in the Time Vault. Gideon soon turned to join her creator, Barry Allen, after Team Flash discovered Thawne's true identity as a speedster.
 * Appearance-Stealing Cord: After being trapped in 2020, Thawne monitored Harrison Wells and created a car accident that severely injured him and killed his wife. Later, Thawne used the cord to alter his appearance into that of Wells, disguising himself until he could find a way to return to his home period.
 * Tachyon Prototype/Tachyon Enhancer: Thawne attempted to steal the Tachyon Prototype from Mercury Labs prior to murdering Nora Allen. He was thwarted by The Flash he soon travelled further back in time, creating a Tachyon Enhancer of his own and stored it in the Time Vault. The Tachyon Enhancer was later converted for Firestorm to split the merging.
 * Wheelchair: While disguising himself as Harrison Wells, Thawne pretended to be injured by the Particle Accelerator Explosion and posed as a paralysed individual in front of his colleagues. However, it was soon revealed that the wheelchair not only allows Thawne to maintain his illusion but also charge his speed, enough for him to maintain his connection with the Negative Speed Force but not enough to charge him to return to the future. Like the Tachyon Enhancer, the wheelchair was converted for Firestorm into the Power Cane for Martin Stein's unstable status.
 * Time Sphere: Thawne possessed a futuristic time machine initially allowing him to return to his home period.
