Reverse-Flash is a name applied to multiple supervillain characters who serve as recurring antagonists to the various heroes called the Flash. The identity is most commonly associated with speed-themed enemies whose costumes and abilities are designed as an inverse or mirror of the Flash. These characters appear in American comic books and related media published by DC Comics and are often central to storylines about time travel, identity, and the nature of the Speed Force.

Main incarnations and notable versions
Several different people have taken the Reverse-Flash mantle across the decades. A few of the better known include:
- Edward Clariss — originally called the Rival (sometimes Rival Flash), a Golden Age scientist who first appeared in 1949 and was presented as a deliberate foil to the Golden Age Flash.
- Eobard Thawne — often called Professor Zoom, a future-era foe associated with Barry Allen’s rogues gallery; he is portrayed as a dark reflection of the Flash, with motivations that mix obsession, hatred and time-manipulation.
- Other later variants — comic-book continuity has introduced additional characters who used Reverse-Flash-like identities or similar powers; some differ in origin, methods and the metaphysical source of their speed.
Appearance and powers
Visually the Reverse-Flash costume is deliberately the inverse of the Flash’s: typically yellow or gold with red lightning accents where the Flash’s suit is red with yellow lightning. Functionally, most Reverse-Flash characters possess speed-related abilities—high-velocity movement, accelerated perception, and access to time-travel or temporal disruption—but the exact scope varies by incarnation. Some use devices or scientific means, others tap into the Speed Force or rival concepts that oppose it.
Origins, themes and development
Introduced as counterpoints to the Flash, Reverse-Flash figures often explore themes of mirrored identity, obsession with a hero, and the consequences of altering time. Writers have used them to challenge the moral and psychological limits of the Flash protagonists: by being versions of the hero turned violent, they dramatize how small changes in choice or circumstance can produce opposite outcomes.
Appearances and cultural impact
Reverse-Flash characters have recurred across comic-book eras and have been adapted into animated series, video games and live-action productions. These adaptations help cement the character’s role as a signature Flash adversary and examine ideas such as legacy, destiny and the ethics of time travel.

Distinctions and common confusions
Not every speed-based enemy of the Flash is strictly a "Reverse-Flash." Some villains who resemble or oppose the Flash go by names such as Zoom or other aliases and may draw power from different sources or motivations. When discussing these characters it helps to distinguish the particular individual, their origin story, and which Flash they oppose—Jay Garrick, Barry Allen, Wally West or others—because the relationships and continuity differ across eras and reboots.
