Eobard Thawne (Earth-Prime)/Time Remnant

"You wanna be like Flash, be a superhero? I wanna be bigger than a superhero, I wanna... I wanna recharge power grids, I wanna reverse tornadoes before they destroy cities and towns, I wanna end famine, end war. I want to save the world. But it wasn't meant to be."

- Meena Dhawan and Eobard Thawne

Eobard Thawne was a time remnant of the original Eobard Thawne, which separated after The Flash's actions during Flashpoint.

Creation
When The Flash caused the Flashpoint timeline by running back in time to save his mother's life, he pulled Eobard Thawne from that point in time, thus creating a time remnant. When Flashpoint began to show negative impacts on Allen's life, Thawne was asked to restore the timeline by murdering Nora Allen once more, which he gladly accepted. Despite Flashpoint being undone after Nora's assassination, Thawne was preserved to ensure the timeline integrity and was allowed to escape. His status as an anomaly soon led to the Time Wraiths and Black Flash's pursuit.

Search for the Spear of Destiny
In order to save his own life, Thawne sought out the Spear of Destiny, a Biblical relic capable of rewriting reality. To accomplish this, Thawne formed the Legion of Doom alongside Damien Darhk and Malcolm Merlyn. Despite the Legends of Tomorrow's attempts to prevent this, they were ultimately unsuccessful, and the group created the Doomworld alternate reality, in which Thawne killed a version of Ray Palmer. However, this new reality was eventually undone and Thawne was captured and vaporized by the Black Flash.

Guardian of the Fixed Point
Thawne was soon resurrected by the Time Wraiths, stripped of his powers, and re-educated into believing that the timeline should not be changed. He was then placed in Sarajevo on June 28, 1914, and assigned to ensure the assassination of Archduke Franz Ferdinand so that World War I would occur. To ensure this took place, Thawne was given a time manipulator which kept him in a time loop and allowed him to freeze time when necessary.

Every morning, Thawne ate oatmeal, stretched, and meditated before going to work protecting the fixed point from time travelers attempting to change the timeline. The routine went on for years, eventually, he encountered Sara Lance, who was attempting to change the timeline to attract the Robot Legends, after she stopped time to deal with whoever was preventing her mission. They briefly fought before Thawne suggested explaining the situation over a drink, and afterwards, the two resolved to work together. Thawne agreed to allow the assassination to be delayed by forty minutes while the Legends attempted to take back the Waverider, though he stated that he would kill the Legends if it became necessary.

Thawne successfully delayed the assassination, but the Legends' plan began to fail when the other time travelers from the Fixed Point Bar began to attack the Robot Legends, who made short work of them. They then began to search for Thawne, who was ultimately stabbed by the robot version of Lance after ensuring that the final assassin succeeded in killing Ferdinand. Lance found Thawne moments later, though she was too late to save him. He told her to protect the fixed point before he died, and the time manipulator detached from his wrist. Thawne was succeeded as the protector of the fixed point by the robot version of Nate Heywood after he was tricked into doing so by the real version of Heywood.

Resurrection
Once again, Thawne was resurrected and with his memories erased. Thawne, now reformed and powerless, was placed in Central City 2021. During his time as a scientist, Thawne was hired by Meena Dhawan as the chief of engineering at Fast Track Labs, where he was able to solve Dhawan's speed equation with ease.

Thawne and Dhawan soon fell in love with each other when they constructed the BLOC (Biometric Lightning Oscillation Chamber), an invention created by Thawne two centuries in the future, before he became the Reverse-Flash. Albeit his original intentions to use the chamber for himself, in hopes of being a hero greater than The Flash, his love for Dhawan changed his mind as she fell into cardiac arrest. With any signs of doubt, Thawne placed her in the chamber and activated the machine, giving her temporary superhuman speed and allowing her to heal from her heart disease.

Someone Better
In 2023, Barry Allen visited Fast Track Labs and expressed his interest in ensuring the safety of the BLOC. Dhawan introduced Thawne to Allen, surprising the latter due to their long-time feud and the recent imprisonment of Thawne's original self. With no memory of their previous encounters, Thawne was confused when Allen accused him of deceiving Dhawan.

After questioning Thawne's original self, Allen returned as The Flash to prevent Dhawan from activating the BLOC once more due to its hidden connection to the Negative Speed Force. Unfortunately, Allen's accusation against Thawne inflicted negative emotions in Dhawan, who was then controlled by the Negative Speed Force. Thawne and Allen were knocked unconscious by Dhawan's lightning. Minutes later, they woke up and argued with each other, with Allen once more accusing Thawne of planning the incident. With no intention of causing such incident, nor having any memories of the Negative Speed Force, Thawne revealed that he was in love with Dhawan, which caused the incident. Allen realized he had made a mistake, and that Thawne was truly who he claimed to be. Allen apologized for treating Thawne like his villainous counterpart, asking for his help to find Dhawan.

Working with Team Flash, Thawne located Dhawan at the Keystone Cleveland Dam and approached her. Thawne expressed his love and successfully restored her mind, and got the approval from Allen that they could continue to use the BLOC with Dhawan's love for Thawne being the "lightning rod" to guide her away from losing her mind.

Negative
With the permission of The Flash, Thawne and Dhawan continued to access the Negative Speed Force, with the later now donning a protective suit as Fast Track.

Later, the Negative Still Force, Negative Strength Force and the Negative Sage Force attempted to erase all Thawnes from existence. The Flash arrived and escaped the Negative Still Force's time manipulation, saving Thawne from his demise and starting a conflict with the forces.

The Negative Forces eventually returned and attacked Fast Track Labs, though was held back by the "B team" consisting of Allegra Garcia, Cecile Horton and Chester P. Runk. Meanwhile, The Flash taught Dhawan to share her speed with Thawne, temporarily giving him superhuman speed to help repel the threat. Thawne then gained a connection to the Negative Speed Force, and donned the Reverse-Flash Suit.

During the battle, Thawne and Dhawan, both inexperienced, were controlled by the Negative Still Force as The Flash battled the other forces. The Flash instructed them to run in circles to distract the forces, while he built up an enhanced lightning bolt charge from his body. Unfortunately, Iris West-Allen appeared out of nowhere in front of the lightning bolt, with The Flash unintentionally killing his wife. Thawne and Dhawan watched in shock, though was even horrified by the former's sudden pain. Thawne clenched his head in pain, as his original self ripped through the flesh and taking his place.

Powers

 * Negative Speed Force Connection: As a time remnant of the original Reverse-Flash, Thawne possessed his original counterpart's superhuman powers from a connection to the Negative Speed Force.

Using the BLOC, Thawne was able to briefly connect to the Negative Speed Force once more, though was killed mere hours by his original self.

Abilities

 * Hand-to-Hand Combat: Thawne was a skilled hand-to-hand combatant, being able to competently fight Sara Lance without his powers.
 * Genius-level Intellect: Despite having no memories of his past as a villainous speedster, Thawne retained his intellect from the 22nd century and subconsciously solved equations as well as built machines that he had previously worked on.
 * Engineering: Using relatively primitive technology compared to those of his home period, Thawne was still able to build an advanced Biometric Lightning Oscillation Chamber that supposedly harness lightning from the Earth's upper atmosphere into artificial lightning, though actually accessed the power from the Negative Speed Force.
