Quote1 It always bothers me when people call it a "power." Because it is so much more than that. The way The Flash uses the Speed Force to be a hero shows it is a blessing. The Speed Force is more than a power. It is hope made real. But with all blessings in the Multiverse there has to be a cost. A burden to that opposite...a negative...a reverse. Quote2
-- Eobard Thawne src

Eobard Thawne, otherwise known as the Reverse-Flash and Professor Zoom (or simply Zoom), is a scientist and criminal from the 25th Century who was obsessed with The Flash. Having given himself similar powers to the Flash, he travels through time to battle his greatest enemy.[1]

25th Century

In the year 2463, when he was a child, Eobard Thawne saw his father kill his mother. [2] Eobard would eventually become obsessed with The Flash, a speedster hero from the 21st Century.[1]

When he reached adulthood, Thawne became a scientist studying the Speed Force. During his research, he managed to create his own "negative" version of the Flash's power source, turning himself into a unique speedster with additional abilities that the positive Speed Force didn't offer.[1] However, for reasons unknown, he would begin to despise his "best friend" and became the Reverse-Flash, a.k.a. Professor Zoom.[3]

In Thawne's native time period, his costume would be on display in the Flash Museum, front and foremost among the hero's enemies.

Destroying Flash's past

The earliest form of meddling Thawne had in ruining the Flash's life was, when Barry Allen was a child, Thawne broke into his house at night and killed the boy's mother before disappearing back in time. Without any proof that a time-travelling speedster had killed her, Barry's father Henry was falsely accused and sentenced for the crime, leaving the boy who would one day become the Flash without his parents and in the care of police officer Darryl Frye.[1]

For years, the Reverse-Flash and the Flash would battle one and other, with him always being faster than his foe,[3] leaving Barry worried that he'd kill someone else close to him.[1] At one point in Thawne's life, he was killed by Barry snapping his neck.[4] Daniel West, the brother of Iris West, later succeeds Eobard in taking on the mantle of the Reverse-Flash - though Thawne wouldn't consider him one, viewing Daniel as an insult.


Professor Zoom and his acolytes

Looking to further harass his nemesis, Eobard gathered allies throughout time by secretly ruining their lives as well, pretending to be a beacon of light during their dark time. After gaining each ally's trust, Thawne would tell them he needed their help in defeating a "demon" in the future known as the Flash, which they all agreed.[5]

With his metahuman "acolytes" by his side, Thawne then began to put his plans in motion by arriving at a point in time when the Flash was an established hero, several years into his career. Finding ways to torment the Flash, Professor Zoom's first move in this time period was initiating for Henry Allen to break out of jail, while also framing him for killing a guard in the escape. While the Flash was forced to deal with the police manhunt for his father, the Reverse-Flash continued his plot to ruin the Flash's history by framing him for putting a bomb in police headquarters.[6]

Face-to-face with his "old friend",[7] the Reverse-Flash and his team battled the scarlet speedster while Thawne simultaneously attempted to use a power-stealing glove to take away the Flash's speed. However, Thawne's plan began to come undone when his team betrayed him, having discovered their leader's true motives.[8] Running faster than he'd ever run before, Barry learned he had the power to actually speed up time, allowing him to arrest Thawne and have him imprisoned at Iron Heights.[2]

The Button

Reverse-Flash discovers the mysteries of the button

Following Wally West's return from being stuck inside the Speed Force, Thawne, still in his cell in Iron Heights, was mysteriously struck by another bolt of lightning that restored memories of his previous life before Flashpoint. [9]

Fleeing Iron Heights, the Reverse-Flash made his way to the Batcave, where he began beating and taunting Batman, explaining that he now remembered Flashpoint and his death at the hands of that timeline's Batman.[10] After beating Bruce to a pulp, Thawne went to examine the mysterious button that Batman had been investigating and, interacting with the residual power, was teleported into the timestream, where he apparently discovered the button's true owner.

While heading to confront the owner in the timestream, Thawne encountered the Flash and Batman, travelling through time from the near future, pursuing him on the Cosmic Treadmill.[11]

Planning to undo Barry's life once again by turning him into his son and acolyte, Thawne outran the two and eventually made his way to where the button's radiation had led him. He demands the button's true owner to reveal himself, and when he does, Thawne becomes frightened for his life. Thawne then starts to become disintegrated by this being, and is teleported back into the batcave, burning in blue flames and claiming that he had seen "God." The Reverse-Flash then collapsed, seemingly dead.[12]

The Color of Fear

However, Thawne was able to survive his near-death experience via regeneration from his negative energy. He is present at Iris West's house when she arrives with her nephew following Multiplex's attack at Barry's birthday party, shocking and terrifying the pair.[3]


  • Negative Speed Force Generator: Thawne created his own negative version of the Flash's Speed Force, with its own unique energy signature, which he can tap into as normal speedsters do with the positive Speed Force. The Negative Speed Force grants him the ability to move at incredible speeds, among many other superhuman powers.[1]
    • Superhuman Speed: Thawne is capable of moving at vast superhuman speeds.[11] His immense speed allows him to generate superhuman force, which allows him to deal devastating blows to opponents, as well as effortlessly hurl them with great force.[10] He is described as faster than both Barry Allen and Wally West, by the Flash himself.[3]
    • Superhuman Reflexes: Thawne possesses reflexes far greater than a normal human being. This allows him to easily react to danger and events, and perceive the world in slow motion.[10]
    • Superhuman Stamina: Thawne's body can handle the stress of moving at superhuman speeds for long periods of time without getting tired or weak.[10]
    • Superhuman Agility: Thawne's agility, balance, and bodily coordination are enhanced to superhuman levels. This allows him to easily maneuver while moving at superhuman speed.[10]
    • Superhuman Strength: Thawne possesses sufficiently enhanced strength, as he was able to effortlessly lift and dangle the Flash with one hand, high above his head. He is also strong enough to easily carry a full grown man with one arm while running,[13] as well as send a man flying several feet with a backhand.[6]
    • Superhuman Durability: Thawne can resist tremendous kinetic impact forces with ease. He was able to strike Batman with multiple, torturous hits, all while sustaining no injuries nor feeling any pain.[10]
    • Absolute Existence: Thawne is immune to alterations to his personal timeline due to the creation of Flashpoint turning him into a "living paradox." This means no matter what, he can not be erased from existence or altered in any way, making him the sole constant in a sea of potential timelines.
    • Cosmic Awareness: Thawne was able to "feel" the presence of who the power of the button belongs to, "like a wave of static electricity", and is aware of their alterations to time and reality.
    • Dimensional Travel: Thawne is able to travel in and out of the Speed Force. With guidance from "the button", he was also able to travel to another unknown plane of reality.[1]
    • Electrokinesis: As a conduit of the Negative Speed Force, Thawne generates his own unique energy signature. This lightning emanates off of him as red electrical arcs from all around his body, and from his eyes as streaks, especially when he moves at super speed.[10] Thawne's lightning can interfere with, and fry electronics.[1]
      • Fatal Touch: Thawne can use his negative energy to rapidly age a person to death, by creating an electrical field around their head and focusing it with his hands.[3]
    • Enhanced Senses: The Negative Speed Force grants Thawne enhanced senses that allow him to perceive the world at a rate attuned his reaction speed.
    • Molecular Control: Thawne can vibrate his own molecular structure at varying degrees for a number of purposes, by adjusting to different frequencies.
      • Intangibility: By vibrating his molecules on an atomic level, and by doing so at just the right frequency, Thawne can allow himself to become intangible, allowing people or objects to pass right through him.[10]
      • Phasing: By vibrating his molecules on an atomic level, and by doing so at just the right frequency, he can allow himself to become momentarily intangible, and phase through objects.[10]
    • Regeneration: Thawne can regenerate from injury much faster than any normal human, and is able to regrow whole body parts.[3]
      • Immortality: Thawne's regenerative capabilities effectively make him unkillable, granting him a potentially perpetual lifespan.
      • Resurrection: Even after being disintegrated by "God", Thawne's ability to regenerate whole body parts allowed him to be resurrected from death itself.[3]
    • Retrocognition: After being hit by lightning in his holding cell at Iron Heights, Thawne regained memories of his old life and his death at the hands of Thomas Wayne in the alternate timeline, Flashpoint.[9]
    • Shock Wave Projection: Thawne possess the ability to create very powerful sonic booms and shock waves with just the clap of his hands.[10]
    • Time Deceleration (Possibly formerly, see notes): Thawne could slow down the flow of time, making himself appear faster than everyone and anything else.
    • Time Travel: Thawne can use his speed to freely travel throughout time, and does not need assistance from the Cosmic Treadmill, like Barry Allen and Wally West.[1]
      • Reality Alteration: Thawne's ability to travel throughout the timestream allows him to manipulate events at will to satisfy his own needs.[1]


  • Genius Level Intellect/Science: Thawne's brilliant mind and broad science acumen enabled him to create a "negative" version of the speed force in order to fuel his own powers.[1]
  • Deception: Thawne organized each of his acolytes' origin stories, forcing them to trust him as the malevolent speedster came to "save" all of them at just the right time.[5]
  • Hand-to-Hand Combat (Advanced): Utilizing his speed, Thawne created an effective fighting style to combat all types of material opponents.[2]
  • Historiography: Thawne is very knowledgeable on world history and culture, spanning from the Flash's 21st century all the way to Magali's ancient times.[5]
  • Intimidation: Thawne's intimidating presence can be attributed to his immense power and sociopathic mentality.
  • Leadership: Thawne led a team of his own "acolytes", dedicated to taking down the "demon" Flash.[5]
