Eobard Thawne/Earth-1666

Professor **Eobard Thawne** (born 2151; as **Orias**) is the son of Michael Demiurgos and unnamed woman. He is also known as the **Reverse-Flash**, was a meta-human speedster from the twenty-second century, a descendant of the late Eddie Thawne, a time criminal, and the archenemy/cousin of Barry Allen/The Flash/God, Obsessed with the twenty-first century's Flash, Eobard recreated the accident that was behind the Flash's powers, becoming a speedster himself. However, after his very first trip back in time, Eobard learned that he was destined to become the Flash's archenemy and grew to despise the hero, attempting to prove his superiority as the Reverse-Flash and becoming the opposite of his former idol. This included creating his own negative version of the Speed Force using negative energy and emotions, which he used to travel through time without the Flash being able to detect him. Since then, the two speedsters battled each other for many years, but neither of them was strong or fast enough to defeat the other.

* **Speed Force-Negative Speed Force connection/Meta-human physiology:** Replicating the circumstances behind the Flash's powers, Eobard gained access to the Speed Force. But sometime later, he created a machine that tapped into the Negative Speed Force and became connected to it and became its avatar; thus, his physiology has been greatly augmented to beyond peak human performance, letting him handle extreme physical exertion and performance. His connection to both the Speed Force and Negative Speed Force grant him the power to not only sense the Flash and other speedsters connected to the Speed Force, but he can also remain undetected; such as why the Flash could never anticipate his nemesis' arrival and time manipulations. However, after Eobard's death in the crisis, he turned into negative tachyons and could only tap into the Negative Speed Force if he had a willing host body. As the Speed Force made him whole once again, his connection to his Negative Speed Force remains intact and he doesn't need a host anymore. As a speedster, Eobard is one of the most powerful beings in the entire multiverse. But after Barry severed Eobard's connection to the Negative Speed Force; he no longer possesses any powers as he is now just a normal human. Another version of Thawne lost his speed as well after being stripped of his powers by the Time Wraiths, leaving him with no speed whatsoever, however, he still had enough of a connection where the Time Wraiths could seemingly resurrect him once more. After tearing through his good counterpart, Eobard regained his speed. After gaining a connection to the other Negative Forces as well, Eobard became one of two of the most powerful speedsters alive, the other being Barry after absorbing the powers of the Positive Forces. At that point Eobard had become so dangerous that Barry was willing to finally let him die as he knew the world would never be safe with Thawne still alive.
	+ **Accelerated healing factor:** The Speed Force in someone's blood gives it regenerative properties. Eobard's body heals much faster and more efficiently than normal humans. His wounds from being attacked were completely gone without a trace afterwards, which he covered up by isolating himself to avoid speculation of any kind. After being viciously pummeled by the Flash of 2016 twice, he is able to recover as if he had never been hurt.
		- **Superhuman longevity:** Due to Eobard's accelerating healing factor; he ages much slower than normal humans. Despite having spent nearly 30 years in the past, his appearance and performance remains the same as ever (albeit the alterations from stealing Harrison Wells' form may have contributed to it) while Eobard was stuck in Iron Heights Prison in the future, his hair started to turn gray over a period of 15 years; as a result of him aging naturally. However, when Cicada's dagger was destroyed in the past and Eobard regained his powers, his hair turned back to it's original black color.
	+ **Bodily vibration:** Eobard has the ability to vibrate any part of his body at different frequencies on command, with varying effects. When done, this is seen as a haze that normal people can't perceive clearly. It can also garble his voice into a deep growl to disguise. By vibrating rapidly, Eobard was able to Reverse his modified appearance-stealing cord's effects, which the device could also do for him with a push of a button.
		- **Intangibility:** Eobard can seamlessly phase his arm through an individual, killing them instantly without outwardly damaging them. By vibrating the cells in his body, Eobard can pass through other individuals or objects unharmed. As Cisco Ramon remembered his own death at Eobard's hands, Cisco described Eobard as having crushed the heart with his fist, performing this same technique on Mason Bridge in 2015 and Rex Tyler in 1942. This power appears to have damaging effects on electrical equipment; as it shorted out Mason's computer.
	+ **Electrokinesis:** Eobard can produce powerful red electricity from his body. The intensity of his lightning is so great that the moment he arrived at the stadium for Barry's first fight with him, the electrical lights and video screens around it started glitching and flashing. Eobard is also capable of making his eyes glow bright red, which most likely is another effect of his electrokinesis. From a stationary position, Eobard can generate a continuous stream of lightning to launch at a target. He can also generate various constructs to be used in battle, such as swords, as well as throw lightning. Upon increasing his speedster powers with the Negative Forces' aid, Eobard's lightning has grown so powerful that he is now capable of generating a gigantic wave of electricity capable of wiping out entire cities.
		- **Flight:** After augmenting his connection to the Negative Speed Force through his newfound connection to the other Negative Forces, Eobard can now generate powerful streams of electricity underneath him to take flight into the air.
	+ **Superhuman durability:** Eobard's durability is well-above that of normal humans, as he is able to endure attacks and exertions much quicker than normal and survive impacts that would be fatal or at least permanently disabling to normal humans. In 2015, he was able to both withstand and quickly recover from pyrokinetic blasts from Firestorm on multiple occasions, being shot with multiple arrows, and being pummeled by the Flash's enhanced strength and momentum. During his fight with the Flash, Firestorm and the Arrow, he also hardly fazed after falling from a building to land from several stories up unfazed by moving at super speed at the same time. After being smacked by the Kryptonian Supergirl, Eobard was able to stand up without struggle seconds later. He is also able to withstand the brutal, frequently occurring punishments he receives in his Iron Heights cell.
	+ **Superhuman mental process:** Eobard's powers also make his system and thought processing able to take in and retain information just as fast and efficiently. Even while using his raw speed, he can clearly think, react to events, and perform actions long before normal humans can perceive them.
		- **Accelerated perception:** Eobard's speed also extends to his senses and mental capacities. He can take in information and process it at much faster rates than a normal human, as well as see and hear clearly when moving at super-speed. This ability allows Eobard to see the world as if it is in slow motion, which, combined with his physical speed, lets him perform thoughts and actions long before a normal human around him could even perceive them. When Barry was running at Mach 2, Eobard was able to follow these movements with ease, and does this again when Barry travels to the past under his guidance.
	+ **Superhuman speed:** Eobard is able to move at levels of speed well above Mach 2.2, easily outpacing Barry Allen's limit during 2014-2015. Using this speed, he can easily move on vertical structures and ceilings. Barry said that he is so fast that he could kill everyone in the police precinct in seconds, describing him as "*somebody that even I can't keep up with.*" His tremendous speed was later revealed to be greatly influenced by tachyon particles in his body. As revealed by Caitlin Snow, this allows Eobard to with each stride his feet spend less time on the ground, thus; propelling him forward much faster, similar to Hunter Zolomon with the Velocity serums. Later, after somehow returning from erasure, his speed also somehow increased considerably, able to keep up with the Flash of 2017 who was described as the fastest speedster ever. However, Eobard also stated that his speed was equal to the Flash of 2024's speed, so it's also possible that he simply realized that Barry had reached that potential and ran using the full extent of his speed. Eobard has stated that he is even faster than Superman. Although Eobard was still exceptionally fast after the Speed Force made him whole once again, his speed proved to be inferior to that of Barry, who had finally surpassed his former mentor in terms of physical speed.
		- **Aerokinesis:** Using his speed, Eobard can generate air flow as vacuums on various levels. He can create fierce waves and vacuums of air by shaking a body part very fast. His speed vacuum is very powerful, as he was able to blow Firestorm blocks away by rotating just one hand in 2015.
		- **Interdimensional travel:** Eobard can apparently use his speed to break down barriers between parallel universes, enabling him to travel to them. Doing this, he was able to travel to Earth-X, where he was able to use his knowledge of different universes to earn der Führer Oliver's trust.
		- **Speed mirage:** By using his speed to bounce back and forth so quickly, Eobard can create after-images with his speed, making it appear like he's in two places at once, no matter how far they are apart. This image is so realistic, that a human mind can't perceive the difference. Eobard can also create mirror speed projections while retaining his peak speed, as demonstrated when he took on both Barry and Nora. For experts of this ability, these mirages temporarily make a speedster in two places at once as seen when Eobard first beat himself up to steal the tachyon device and when fighting Nora and Barry before rejoining into one person again.
		- **Superhuman agility:** Eobard possesses inhuman bodily coordination, balance, equilibrium and dexterity. He is able to change direction immediately, thus allows him to make sharp turns on city streets without sliding or losing his balance.
		- **Superhuman momentum:** Eobard can generate an inhuman amount of physical force from any part of his body, especially while using super speed. This allowed him to exert inhuman physical strength with almost absolute ease, commonly to restrain opponent at super speed and pinning them down with little effort, as well as to kill his opponents through high-speed collision. By channeling this force to his strikes, even the Flash was quickly pummeled and rendered unable to fight back despite healing powers. When he faced the Black Flash in 2025, Eobard punched with enough force to send the creature flying through several rooms before slamming against the far wall. He could also punch clean through people, as he did do impale Bridge on his arm in 2015 and even to punch through his chest-piece of the A.T.O.M. Exosuit to tear out Ray's heart in 1916. Alternately, when Eobard removed Ray's heart, he may've phased his hand through Dr. Palmer's chest, much like he did when he crushed Cisco's heart in an erased timeline.
		- **Superhuman reflexes:** Eobard's increased speed also augments his reaction time; allowing him to react to danger and events far faster than normal humans.
		- **Time travel:** Using the Negative Speed Force, speedsters such as Reverse-Flash are able to conduct chronokinesis or temporal manipulation, which allows him to travel throughout time. Unlike users of the Speed Force, Eobard's ability to travel through and manipulate time is more refined compared to other speedsters as he is easily able to drastically alter history and completely erase people from existence (other speedsters cannot change the past without dramatic consequences). This ability has also allowed Eobard to continue existing despite being erased from existence in the current timeline. However, when using the Speed Force Eobard does have side effects such as watching for Time Wraiths and has his Speed Force time remnants able to be erased by the Black Flash.
			* **Time remnant construct:** By shifting momentarily back in time, Eobard is able to "create" a time remnant. As each one is as real as the other, it allows Eobard to overwhelm his enemies with multiple versions of himself. It also protected him from any alterations to the timeline and secures his existence when he shouldn't exist by becoming a time remnant himself. As a time remnant, he was also able to create his own time remnants.
			* **Temporal immunity:** Due to Eobard's connection to the Negative Speed Force; he exists outside of the time; for example, when his ancestor, Eddie Thawne had committed suicide that erased all future members of the Thawne bloodline from the timeline, Eobard still remains in existence. Even if Eobard is not responsible for altered the timeline; he is still completely unaffected by it, as he still maintains his memories from original timeline of the original multiverse.
			* **Retrocognition:** When existing as a time remnant, Eobard retained memories of his former life masquerading as Wells, as seen when his time remnant self reminisced about working with Cisco and Caitlin. When Barry visited a version of Eobard as Wells, Eobard was quite familiar with Savitar even though Savitar was not part of the original timeline. Eobard apparently remembered events from both the pre- and post-Flashpoint timelines, as his post-Flashpoint self was aware of Ralph Dibny's death, an event from the pre-Flashpoint timeline, but he also remembered Barry and Nora's visit to 2015, an event from the post-Flashpoint timeline.
	+ **Superhuman stamina:** Eobard's body can handle the stresses of superhuman racing without noticeable distress. His body's enhanced stamina allows him to function much longer than a normal human without getting tired or weak. Therefore, he is also adapted to the extreme amounts of force exerted on him while he is moving at super speed, as well as the extreme temperatures and lessened amount of breathable air.
	+ **Superhuman strength:** Due to the tremendous amounts of Speed Force energy in his body, Eobard displays a degree of superhuman strength, exerting inhuman amounts of force without using his speed. He was also seen punching Mason which made Bridge go all the way up to the roof and as the man came falling down he once again punched his victim, making Mason go all the way across the room. From a stationary position, he was able to throw the Flash several yards away with one arm. As means of intimidation or restraining, he has repeatedly been shown able to easily hold down, or even pick up, a full-grown adult with a single hand, usually by their necks. He was also was able to effortlessly break a man's neck. Eobard's method of intimidation/restraining has been done on Rex in 1947 and Malcolm Merlyn in the Vanishing Point, and method of breaking a man's neck has been done on Mercury Labs' various staff and the CCPD in 2014-2016, and government agents while protecting Damien Darhk in 1987.
* **Negative Still Force connection:** At some point, after being humiliated by Barry's superior speed, Eobard tapped into the Negative Still Force in order to manipulate time and events more easily and more subtly, and used this advantage to frame Barry for working with Joseph Carver, killing Joe West, and other actions conductive to the ruin of Barry's life; even making it seem that Barry was the Reverse-Flash while Eobard himself was in fact the Flash instead of Barry. After becoming the avatar of the Negative Still Force, Eobard can now control time with a snap of his fingers.
	+ **Temporal displacement:** With a snap of his fingers Eobard can displace other people and objects in time. He did this to XS, Impulse and Fasttrack sending them back a billion years in time, and again with summoning an old school plane from out of nowhere when fighting the Flash.
	+ **Time stopping:** Eobard can stop others in their tracks by freezing them in time with a snap of his fingers.
* **Negative Sage Force connection:** After becoming the avatar of the Negative Sage Force, Eobard can now augment his mind to access a vast array of psionic powers.
	+ **Illusion inducement:** Eobard can use his psychic powers to create realistic illusions. He made Flash, XS and Fasttrack think they threw lightning at him, when in reality they threw it at Impulse.
	+ **Teleportation:** Eobard can use the Negative Sage Force to teleport around from one place to another.
	+ **Mental detection:** Eobard was able to sense the Flash's approach and react before Flash could do anything about it.
	+ **Psionic tendril generation:** Using his connection to the Negative Sage Force, Eobard can generate powerful tendrils of pure Negative Sage Force energy for offensive attacks.
* **Negative Strength Force connection:** After becoming the avatar of the Negative Strength Force, Eobard can access the full extend of this Force to augment his physical strength. However he rarely used the powers he got from the Negative Strength Force as he preferred using the powers of the other Forces to defeat his opponents instead.

#### Former powers

* **Possession:** After Eobard's death in the Crisis, his essence was reduced to a manifestation of negative tachyons as his physical form was no longer preserved. As negative tachyons, he has the power to possess humans. However, he could not take over the body and connect to the Negative Speed Force until the host was fully overwhelmed by him. However, since the Speed Force gave him back his body, he doesn't need to find a host again.

### Abilities

"*Man, Thawne's plans got plans.*"
—Ralph Dibny
* **Genius-level intellect/Great business acumen/Master tactician/Leader:** Eobard is considered a genius even in the more advanced era of the late 22nd century, having learned astro-navigation in grade school, potentially making him more intelligent than all individuals of the early 21st century (besides Clifford DeVoe) he has displayed in-depth knowledge and understanding of time-traveling like the Time Masters. With this, he was able to effectively evade any encounters with a Time Wraith and confidently travel back over 150 years to change the past with no fear of affecting his own future, as well as to give the Legends trouble balancing the timeline. Eobard is a great tactician, businessman, and leader, having personally founded S.T.A.R. Labs and ran it very successfully for 14 years and was able to effectively lead Team Flash and swiftly come up with plans to help Barry Allen defeat the meta-humans while simultaneously carrying several misdeeds to fulfill his own agenda and preventing them from figuring out that he is Reverse-Flash for nearly a year. In addition, his mastery of contingency plans was also seen by how he had set in place the necessary tools to force everyone to go back into the pipeline, therefore; forcing Team Flash to still help him return to his time even after he had been defeated by Barry, Oliver and Firestorm. After rewriting reality with the Spear of Destiny, Eobard once again proved able to efficiently run S.T.A.R. Labs, becoming a prominent figure in the world of business. Eobard is proven to have great intelligence about the Speed Force and its usage. He has many times helped and guided Barry to use it better. He knew it has powers to create vacuums, move seamlessly pass through any solid target and was able to direct Barry on how-to use the Speed Force to time travel. Eobard also has knowledge relating to mystical artifacts. He knew that the Askaran Amulet was a Judeo-Christian artifact which acted like a compass for the Spear of Destiny as well as knew the object's divine capabilities. He even related some knowledge of the Fasces Axe which Damien Darhk was purchasing. He also revealed he knows about time remnants, when he went up against the Legends. His knowledge and understanding about the Speed Force seems to be among the greatest (if not the greatest) among the speedsters due to him being from the future. Eobard is among the most intelligent individuals in the multiverse and the most intelligent individual on Earth-1.
* **Medical knowledge**: Although never explicitly stated to excel in the medical field, Eobard was still a good enough of a medic to perform complex surgeries, as he was put in charge of transplanting Supergirl's healthy heart into Overgirl.
* **Computer specialist/Skilled computer hacker:** Eobard is a skilled computer hacker, being able to hack into the radio signals of multiple cars in order to destroy Hartley Rathaway's weapons.
* **Master scientist:** Having learned astro-navigation in grade school and dedicated his life to learning the secrets of the Speed Force, Eobard is a vastly knowledgeable, resourceful and ingenious scientist, specializing in various fields of science. Throughout his life, Eobard has been a genius professor, especially a physicist, from the advanced 22nd century, and when stuck in the 21st century as Harrison Wells, while running S.T.A.R Labs, he was able to effectively act as one of the greatest scientific leaders of that time and make great advancement to multiple scientific fields. He has a superb knowledge of meta-human biochemistry and molecular structure, creating a biomolecular enhancer. When given the formula of Velocity 9, Eobard was able to quickly identify a way to disable the artificial speed. This may all be because he's from the 22nd century. His greatest feat of science was his successful replication of the Flash's accident to replicate his former idol/future archenemies' powers for him self and he even created his own method of being a speedster and time travel by tapping into the Negative Speed Force, a force leeching power from the Speed Force and fueled by negative emotions and negative tachyons, in order to be a speedster yet be undetectable by the Flash, as well as a means to be protected from his existence being erased from his ancestor's death.
* **Master of deception/Manipulator:** Eobard is highly accomplished at deceiving people, as he was able to work closely with Team Flash for months as Harrison Wells without them knowing who he really was and even deceive those close who had known the real Harrison Wells, all but Tina McGee. He is also an excellent manipulator, as he managed to effortlessly manipulate Tony Woodward and Hannibal Bates respectively into helping him. He even manipulated Nora West-Allen into trusting him, telling her to help punch DeVoe's satellite in order to manipulate the timeline and create a Cicada that Team Flash could defeat in order to destroy Cicada's dagger which was dampening his powers in the future, thus freeing him.
* **Master engineer:** Eobard is highly proficient in the art of engineering due to his consummate knowledge of futuristic technology from 22nd century, as he successfully created and modified the particle accelerator with only the resources of the 21st century, recreated the tachyon device into a quantum splicer with Cisco's help and was able to create the ring that contains his suit, the Time Vault, anti-speedster guns, and the appearance-stealing cord, which he managed to modify to be nonlethal to the person whose appearance is being mimicked, allowing him to keep Martin Stein alive. Eobard, while serving as a SS General on Earth-X, even designed and constructed the *Wellenreiter* mostly on his own.
* **Multilingual:** Eobard is capable of fluently speaking English and Latin. He can also read and write in the time language.

"*Newsflash, Raymond: I don't need super-speed to kick your ass.*"
—Eobard Thawne to the Atom
* **Expert hand-to-hand combatant/Martial artist:** Though suffering a beating at the hands of the Flash from 2016 in his first encounter, Eobard eventually became a seasoned expert of hand-to-hand combat, being able to fight on par with the Flash of 2024 and easily defeated the younger Flash from 2014-2015 in multiple fights, along with later on winning two fights with the 2017 Flash, who's speed equalled his, before being defeated in their final fight. Whereas the novice Flash from 2014-2015 relied primarily on speed to overwhelm slower opponents with random striking, the older Eobard proved to be a very methodical combatant, using his speed to seamlessly and quickly strike at precise spots to systemically wear down his opponent. Even without his speed, Eobard's fighting skills on their own right proved formidable, capable of trouncing Ray Palmer in his A.T.O.M. Exosuit when they were in a no gravity area, which effectively stripped him of his speed, with solely superior fighting skills, quickly turning the tides after Ray briefly overwhelmed him to swiftly beat and kick him away, with Ray only overpowering him using his suit's blasts and even managed to roughly hold his own against the extremely skilled Oliver Queen, who had already been trained by Ra's al Ghul at this point long enough to regain his speed, able to dodge and block quite a few of Oliver's blows before eventually being overpowered. When in Nash's body and not having his powers, Eobard was still able to outfight Cisco, easily knocking him down and restraining him and breaking out of his grip after being hit and tackling him to a table and ultimately subduing him after easily blocking his attack upon being kicked away. Like his rival Barry Allen, Eobard is also quick to adapt in battle, as shown when they used their newly created lightning swords against the temporarily much faster Godspeed, with their combined efforts proving to be a match for him. When Eobard became the guardian of the fixed point, he proved himself capable of fighting on par with Sara Lance for a short period of time (even without his super speed).
	+ **Skilled knife-fighter:** When fighting Ray, Eobard was able to use a knife to slash him twice before getting disarmed.
	+ **Expert stick-fighter:** When fighting Oliver, Eobard was able to wield a metal pole against the bow-wielding vigilante, hold his own for a time and even land a hit on him though he clearly caught Oliver off guard.
* **Intimidation:** As Reverse-Flash, Eobard possesses an intimidating presence that would force other individuals to give up information or stop an investigation on him. Damien Darhk notably wasn't afraid of him, only his super speed.

### Weaknesses

* **Mental instability:** Eobard is unbelievably arrogant, erratic, cruel, unstable and delusional; for example, after traveling back in time, he discovered that he was destined to become his idol’s greatest enemies, as he could never become like him, he developed an hatred towards Barry Allen. This hatred was further intensified when Eobard was prepared to reveal his existence as a speedster to a crowd in the 22nd century after he had gained enough tremendous speed; which was the first time that Barry and Eobard met each other in real time, however, the scarlet speedster beat him, saving the crowd from an unknown disaster and thus; stealing his moment of glory; albeit that Barry had no intention or desire to upstage him. Since that moment - he became obsessed with trying to destroy Barry's life - spurred on by the grandiose belief that he is superior to the latter. In truth, Eobard lacks any form of morals or honor, all traits that his arch-nemesis stands for. Eobard has a habit of underestimating his opponents - despite years of battling against Barry, he still underestimates the scarlet speedster - which has led to several of his downfalls at the latter's hands. Eobard's obsession with trying to destroy Barry's life almost costs him his own life. After Eobard created the Reverse-Flashpoint timeline not only so that he could usurp Barry's role as the Flash, but also to hurt him, but after Barry used the particle eradication distributor to prevent the Reverse-Flashpoint timeline ever happening again, he was being erased from existence by the timeline itself; even his connection to the Negative Speed Force was not able to prevent this from happening; fortunately, Eobard still remains in existence; due to Barry severing his connection to the Negative Speed Force.
* **Anti-speedster weapons:** The Legends have an arsenal of anti-speedster guns, invented by Eobard himself, which would allow the user to momentarily slow Eobard down. However, Eobard showed himself resistant to the weapons, restoring his powers after mere moments.
* **Particle eradication distributor:** After Barry Allen used the particle eradication distributor to prevent the Reverse-Flashpoint timeline from ever happening, he was being erased from existence by the timeline itself, as it had somehow bypassed his connection to the Negative Speed Force. In order for Eobard to remain in existence, Barry had to sever Eobard's connection to the Negative Speed Force.
* **Positive tachyons:** Since the Negative Speed Force is the opposite of the regular Speed Force, positive tachyons are theorized to weaken Eobard's powers as he produces negative tachyons. However, negative tachyons can also leech off positive tachyons to draw power. This suggests that too much positive tachyons can actually offset negative tachyons.
* **Cold temperatures:** Much like other speedsters, Eobard seems to be weakened or at least momentarily stunned when exposed to an extremely cold environment. This was proven when Leonard Snart's Cold gun knocks Eobard unconscious for a short period of time.
* **Irregular gravity:** Eobard is unable to access his speed while in space or on the moon. While Ray suggests this is because of the lack of gravity, Eobard is still unable to phase or vibrate himself while tied up on the moon, which does possess a gravitational force. However, this may simply be because of the differing gravitational forces of Earth and the moon, meaning that Eobard would be able to phase in that particular level of gravity. Also, he needed to manually restore his normal appearance with the appearance-stealing cord instead of vibrating on his own power. He can however still access his speed and phasing abilities to their fullest effect when Earth-level gravity is artificially replicated (e.g. on the *Waverider*).
* **Nanites:** When Eobard was shot with a nanite arrow, he lost his powers for a short amount of time even though Oliver said it'd take away his speed for "quite awhile", and he could somewhat vibrate; allowing him to phase the nanites out of his body, instantly restoring his powers.
* **Time alterations:** While willing to make huge leaps through time and likewise meddle with events, Eobard has a great fear of time manipulation done recklessly by others. This is due to the existence of the Time Wraiths who act as guardians to the Speed Force's energy. While existing as a time remnant as his past self was erased from existence, Eobard was forced to constantly run, even through the timeline itself, to avoid getting killed by the relentless hunting of the Black Flash, of which Eobard was utterly terrified of facing. After his return from some unknown place, Eobard seemed to have solved his problem with the Black Flash, as he appeared nonchalant when confronted about his previous erasure. He claimed to discover that "the timeline is malleable" and was able to predict the timeline with ease. However, because of the time stone's ability to nullify any time variables, he began to slowly fade away from existence when the stone was used.
* **Electricity:** Since Eobard is like a human battery, if he tries to absorb too much electricity he will blow his fuse and lose his speed as shown when Barry saved him.
* **Power limitation:** After absorbing the powers of all four Negative Forces and becoming a living god, Eobard's body could only handle so much power. This lead to his death, as he overdosed when the Negative Forces gave him even more power and his body disintegrated because of it.

#### Former weaknesses

* **Cicada's dagger:** Cicida's dagger has the power to disable and negate the superhuman abilities of meta-humans who gained powers due to exposure to dark matter, including Eobard. In 2049 it is used to dampen Eobard's powers while he's in prison on death row. However, since Team Flash sent the dagger to the Mirrorverse in 2019, this caused it to vanish in 2049, thereby allowing Thawne to regain access to his powers.
* **Speed Force connection flux:** According to Gideon; Eobard severely damaged his connection to the Speed Force from having traveled back in time and killed Barry's mother, Nora Allen. Even when Eobard's ancestor Eddie committed suicide to wipe Eobard out of existence, the Negative Speed Force continued to exist despite Eobard being the creator, so this implies the Negative Speed Force truly is immune to timeline changes as Thawne said. While later regaining his super-speed and most of its related powers due to setting the timeline back on course through the particle accelerator explosion leading to Barry becoming the Flash, he still lacked a stable connection to the Speed Force; thereby rendering him unable to travel through time, and thus, stranded in the distant past. At the same time, his recovered speed was unstable, randomly working, and also appeared to affect his ability to walk. To compensate somewhat, Eobard relied on the tachyon prototype to stabilize his powers for a longer duration. However, the version that had existed after undoing the Flashpoint timeline never experienced these damaging events and is able to use his powers to their fullest with ease. Later, the original version who wore Harrison Wells's appearance somehow managed stabilize his connection.
* **Lack of physical form:** As negative tachyons, Eobard does not have a stable form and has to possess a person to remain stable as well as the connection to the Negative Speed Force. In addition, when he possesses someone, he has to make them fully give in to their negative emotions (such as Nash Wells's despair and guilt over losing Maya) in order to completely take over their body. Until he's fully taken over his host, he cannot access the Negative Speed Force. However, since the Speed Force gave him back his body, he doesn't need to find a host again.

## Equipment

### Original multiverse

* **Reverse-Flash ring:** Eobard owns a ring with a Reverse-Flash lightning-bolt symbol on it that can open up a wall in the Time Vault that contains a mannequin which he uses to store his Reverse-Flash suit. Eobard is able to hold his entire costume in his ring, and shoot it out of the top, allowing him to change into it at super speed and always have it ready for wear.
* **Reverse-Flash suit:** Eobard wears a protective suit while acting as the Reverse-Flash, to hide his identity from his victims and withstand extreme force. It is similar to the Flash's future suit, but only reversing the colors (red to yellow, white to black).
	+ **Earpieces:** On his suit's cowl, there are two lightning-bolt shaped earpieces, also similar to those on Barry Allen's Flash suit. The suit has wireless communication capabilities through its built in earpieces, though it is unclear what Eobard uses them for, as he is not shown to have any other allies other than Gideon and Grodd. It's possible in his current post-Flashpoint iteration that he uses it to communicate with his teammates Malcolm Merlyn and Damien Darhk, although Eobard prefers to wear a black leather jacket instead of his suit, and as such tends to use wireless earpieces to communicate with them.
	+ **Holographic interface:** The suit has a computer-like connection to Gideon, giving the user portable access to the A.I. It has a holographic projection of Gideon in the center of the suit's palm.
	+ **Retractable half-face mask:** Eobard, as of re-appearing on Earth-X, wears a nanotech mask that only covers the large mouth hole on his Reverse-Flash suit, leaving the glowing-red eyes exposed. For reasons unknown, he has not used it since.
* **Various future technologies:** Eobard has several devices and gadgets from his time at his disposal. Some have been displayed and their functions have been shown, though there are those that are still unknown.
	+ **Appearance-stealing cord:** This device has two cords that are connected to two organisms, corroding one while transferring that one's genetics (especially phenotypes) to the other, allowing the survivor to physically resemble the other in every way. Eobard used this to physically become Harrison Wells. After Flashpoint, Eobard modified this device (or an identical one) to be used without killing the person he uses it on, only causing the victim pain, and allowing him to revert to his normal appearance when he wishes so he is not trapped with any one appearance. Eobard used the modified device on Martin Stein and others during his quest for the Spear of Destiny. Eobard implies having used this to get Harrison Wells's appearance once again upon his return to Earth-One.
	+ **Biomolecular enhancer:** Eobard gave this to the Nazis in 1942 as a bargaining chip in a trade with Adolf Hitler. It was used to mutate Baron Krieger into der Übermensch. Ray Palmer modified Eobard's enhancer into a drug to cure Nate Heywood's hemophilia. As a result, Nate also received meta-human powers of identical to Tony Woodward's.
	+ **Pager:** Eobard has a futuristic watch-like pager which can indicate whenever Black Flash is near.

#### Former equipment

* **Gideon:** Eobard uses Gideon, an advanced artificial intelligence created by Barry Allen; to aid him during his travels through time and when monitoring the timeline.
* **Tachyon device:** After Eobard's connection to the Speed Force began fluctuating, he stole this device from Mercury Labs, using it with the intentions to get faster and stabilize his fluctuating Speed Force connection for longer durations. But once the effects of this device could no longer help him, he converted it into a Quantum splicer for Firestorm.
* **Wheelchair:** After the particle accelerator exploded, Eobard pretended that he became paralyzed in his legs to hide his identity from the team. In addition, a device was stored on the underside of the wheelchair that was charging his super speed which Cisco Ramon eventually discovers. After his identity was revealed to Team Flash, Eobard abandoned this wheelchair which is currently in S.T.A.R. Labs, although he temporarily used it again in S.T.A.R. Labs, possibly for sentimental reasons after re-appearing on Earth-X.
* **Spear of Destiny:** Eobard previously owned the Spear of Destiny, an ancient Biblical relic which was tainted by the blood of Jesus Christ, thus gaining tremendous reality warping divinely supernatural power. Sara Lance used the object's power to depower itself, thus; rendering the holy item useless.

### New multiverse

* **Reverse-Flash ring :** Eobard owns a ring with a Reverse-Flash lightning-bolt symbol, which may has the same utility and the same features as it had in the original multiverse.
* **Reverse-Flash suits:** Eobard wears a protective suit while acting as the Reverse-Flash in order to hide his identity from his victims and to withstand extreme force. The first is version is yellow with red highlights and fades to black on the arms and legs, while the second is more entirely yellow with red boots.
* **Appearance-stealing cord:** Eobard used this device to become Harrison Wells as he did in the original multiverse. It can also be assumed that this device is what allowed Eobard to wear Barry's face when he framed the Flash in 2021.

#### Former equipment

* **Time manipulator:** After being revived and stripped of his powers by the Time Wraiths, Eobard was given a watch-like device that both trapped him in a perpetual loop of the same day and allowed him to freeze time in order to protect the fixed point of Archduke Franz Ferdinand's assassination.

##### Alternate timeline equipment

* **Flash suit:** When Eobard acted as the Flash in the Reverse-Flashpoint timeline, he wore Barry's red Flash suit.
