A one-time enemy of the Golden Age Flash, the Black Widow is Princess Helene. She is a widowed gangster who robbed men, but instead of killing them, her magic wine turned them into animals, which she added to her menagerie. She met her end by drinking the wine herself and turning into a black widow spider, and was promptly stepped on by one of her lionesses.
- The Beastmaster: She collects exotic animals, including lions, chimpanzees, leopards, and cheetahs.
The prince of the magical dimension of Eastwind, Brother Grimm was a boy when Barry Allen and Wally West helped him and his brother overthrow his evil father. Grimm asked Wally for advice, and Wally told him to make his own choices; he gave the crown to his brother, but soon his brother proved just as evil as their father. Grimm killed his brother in battle and became king of Eastwind, blaming Wally for this tragedy. Years later, he came back to ruin Wally's life the same way he believed Wally ruined his: by destroying his home and family.
- Alien Blood: His is blue.
- Dimension Lord: Lord of his own magical dimension

Uninterested in ruling, Grimm takes Kid Flash's advice to "follow his path" and lets his brother take the crown. Unfortunately, Angar proves to be as a bad a ruler as his father, and Grimm is forced to kill him and take the crown anyway.
- Spider-Sense: Can detect the Speed Force, allowing him to hit and dodge speedsters despite not having super speed himself.
- Spikes of Villainy
- "Well Done, Son!" Guy: Didn't get along with his father, the former king.
- I have been chosen by lightning. As have you.
A cult leader who gained immortality from a lightning strike, and who thus considers the Flash as a sort of "brother of the lightning" who his followers worship. They prey on the lives of people who Flash has saved throughout his career, justifying their actions by rationalizing that without the speedster's intervention, those persons would have died anyway, so the cult can kill them with a clear conscience. Cicada equips his followers with special daggers that absorb the life-force out of people stabbed by them, and he intends to use that stolen life-force to resurrect his wife, who he killed in his back-story.
- Aborted Arc: One of the police gets a hit off of Cicada's immortality, and Cicada is shown to briefly entrance him. Nothing more is ever made of it.
- Ax-Crazy: But he's a bit more low-key about it, compared to some other villains.
- Badass Longcoat
- Beard of Evil
- Contemplative Boss
- Driven to Suicide: In his back-story, he attempted to do this after he murdered his wife. He wasn't successful; instead, a bolt of lightning that conveniently struck at that very moment gave him a sense of immortality.
- Evil Old Folks
- Knife Nut: His followers use special daggers that rob anyone stabbed with them of their life-force.
- Mad Scientist: Cicada does what he does to resurrect his wife.
- Religion of Evil: His cult dedicated to the Flash.
Barry Allen's twin brother. The Allens and the Thawnes came to the same doctor for the same reason, because both wives were pregnant and about to deliver; however, the doctor accidentally killed the Thawnes' child, then out of guilt gave them one of the Allens' twins and told the Allens that that twin had died. When an adult Malcolm found out, he set out to destroy Barry for having everything he himself could have had but never did. He utilized a magical blue flame that could rob speed from anyone connected to the Flash legacy.
- Abusive Parents: His adopted parents used him as a tool for their cons and treated him terribly; their knowledge that he wasn't their biological child only made it worse.
- Body Surf: One of his abilities. He's also not limited to one body, as he was able to possess all speedsters up until the 30th century simultaneously.
- Cain and Abel: Though Barry himself never knew it, as Malcolm never revealed himself to his brother.
- Con Artist: Malcolm's adopted parents used a magical blue flame as a miracle healing agent (with temporary effects) to pull stunts like this. Of course, the flame itself was meant for greater purposes, which Malcolm learned and studied from his adopted grandmother.
- Everything's Sparkly with Jewelry: He keeps the flame contained in a blue gem.
- Evil Sorcerer
- Evil Twin: He literally is Barry Allen's twin brother
- Feuding Families: The originator of the Allen-West/Thawne feud.
- Freudian Excuse: Being given away at birth to a bunch of abusive con artists, then later finding out you have a twin who got a relatively good upbringing by your real parents...can you really blame him for being angry?
- In the Blood: He is the progenitor of the villainous Thawne family, whose bloodline includes Reverse-Flash Eobard Thawne and Thaddeus Thawne (Inertia).
- Kill It with Fire: At least one of his descendants used the inherited Cobalt Blue flame to murder his Flash's wife this way.
- Legacy Character: He's a distant ancestor of the Reverse-Flash, Impulse, Inertia, and Captain Boomerang II. As well, there are 1000 years' worth of Cobalt Blues that follow in his footsteps by fighting their respective Flashes (who are all of the Allen or West bloodlines).
- Mundane Utility: Malcolm's adopted father used the blue flame to pull cons. Malcolm's adopted grandmother was disgusted by this, and consequently was delighted to find an eager student in Malcolm, who would subvert the trope by using the flame to its maximum potential.
- People Puppets: Turned several generations of Flashes into this through a Batman Gambit involving shards of his gem, infused with his own spirit.
- The Resenter: Toward Barry, for having the wonderful life that Malcolm got cheated out of.
A gambling addict who was cursed with a set of magically enhanced playing cards after murdering their pervious owner. After discovering that he can control the cards with his mind, Tell became a supervillain and member of the Rogues.
- Body Horror: His cards come from strips of his own skin.
- Cursed with Awesome: Sure, his powers require him to horribly mutilate himself whenever he uses them... then again, psychically controllable enchanted playing cards that can wound Kryptonians is an ability not to be trifled with.
- Death Dealer: Uses enchanted playing cards that can slice through just about anything.
- The Gambler
- Laser-Guided Karma: His enchanted cards are bonded to his skin because he killed their previous owner over a gambling match that went badly for Tell.
- Pungeon Master: Card and gambling puns.
- Steven Ulysses Perhero: Tell? Get it? Like when you have a tell in poker?
A former power plant worker who got exposed to nuclear radiation and essentially became a living radiation battery. He was introduced during the Iron Heights storyline, being kept in a containment cell that used him to power the entire prison. After the Flash found out and confronted Gregory Wolfe about it, Fallout was eventually given improved living conditions where he now continues to power the prison, but the power is siphoned from him in a more humane manner.
- Blessed with Suck: His control over radiation makes him insanely powerful, but is also uncontrollable and makes it difficult for him to socialize with others.
- I Just Want to Be Normal: When he risks giving everyone else cancer and kills plants when he just goes out for a walk, it's easy to see why he'd want this.
- I Love Nuclear Power: Except he really doesn't.
- Meaningful Name: He's named after Niels Bohr, one of the contributors to the Manhattan Project.
- Power Glows
- Power Incontinence: Incredible power that he literally can't shut off.
- Tragic Villain: He wouldn't even be a bad guy if he could at least control his powers.
- Unskilled, but Strong: His powers are very strong, but he doesn't know of anyway to control them.
- Unwitting Pawn: Of Blacksmith. She orchestrated his escape from Iron Heights knowing his path would take him by the Garricks' home, causing Joan to develop cancer, forcing her and Jay out of town for treatment, depriving Wally of Jay's help.
A classically-trained musician who knows how to play magically-enhanced music that can not only hypnotize people, but also destroy objects and create sonic walls. Bowin used his skills to become a professional thief and menaced the Flash many times before a brief retirement.
- 10-Minute Retirement: He retired for a short time, but decided to get back into supervillainy. This attempt ended badly to say the least.
- Aristocrats Are Evil
- Deal with the Devil: In one version of his origin, this is how he learned to play his magical music.
- Evil Old Folks: Perhaps the oldest member of Flash's rogues gallery.
- Evil Twin: Of a successful violinist, Maestro Bowen.
- Killed Off for Real: In his old age, the Fiddler tried out for the Secret Six. It didn't go well; Mockingbird made Deadshot execute him for his failure.
- Legacy Character: The Fiddler had a female successor named Virtuosa whom has only ever appeared in books featuring the Secret Six.
- Magic Music: The Fiddler possesses magical abilities that he channels through his violins.
- Mind-Control Music: The Fiddler is a master hypnotist who can focus his abilities through his violin.
- Musical Assassin
- Sesquipedalian Loquaciousness: Averted. Despite being a classically-trained musician and owning a Stradivarius, Bowin insists upon calling it a fiddle.
Golden Age Star Sapphire
A woman of unknown name from an unknown world, this Star Sapphire was chosen by the Zamarons to be their champion years before the Star Sapphire Corps was formed. She was found unworthy, however, and was banished to the Seventh Dimension. Jay Garrick, The Flash, battled her twice when she escaped. Her connection to later-day Star Sapphires was only made in her third appearance 60 years later.
- Designated Girl Fight: With all the men banished, Joan and other women tried to fight her, but she used her powers to spin them around until they started to disintegrate from the friction. Jay helped get them back to normal.
- Dimension Lord: She's the queen of the Seventh Dimension and has control over all its facets.
- Does Not Like Men: She banished all men from Earth, including the Flash, in her second appearance.
- Multiversal Conqueror: She tried to take over all dimensions at least twice.
- No Name Given: She doesn't have a name, unless her name is Star Sapphire as opposed to it being a title.
- Rogues-Gallery Transplant: In a meta sense, as while she started as and remains a Flash villain the Star Sapphire name became associated with Green Lantern.
- Smug Snake: She's very fond of boasting how her seventh dimension powers make her unstoppable, but is quick to panic when her plans fail.
- Time Master: One of her powers is control over the fifth dimension, time, which Jay combats with his speed.
A renegade from the hidden Gorilla City, Grodd is a mad genius and warlord who wants to destroy humanity and make Earth the dominion of apes. He was endowed with sentience by a radioactive meteor along with the other apes of Gorilla City, but also gained vast telepathic powers. Grodd has a formidable intellect offset by an animal's fury. He originally clashed with Barry Allen and has gone on to menace the entire Flash family.
- A God Am I: In JLApe: Gorilla Warfare. "I am the Lord thy Grodd! All shall bow before me!"
- Archenemy: Had a solid claim on this title during the Silver Age, when he was the only serious threat in the Flash's Rogues Gallery of otherwise Harmless Villains. These days he's more of a general DCU villain, though he still hates the Flash family the most.
- The Artifact/Fad Super/Reimagining the Artifact: Grodd was created at a time when gorillas were something of a fad in comics, TV shows, and movies; unlike most other characters created in that craze, like the Gorilla Boss of Gotham City or the Mod Gorilla Boss, however, Grodd has kept appearing and generally been updated to fit the tone of the times.
- Berserk Button: Do NOT call him a monkey, though unless you really want to make him mad. And he hates bananas.
- Big Bad: Of JLApe and the 1991 Angel and the Ape miniseries.
- Depending on the Writer: Grodd sometimes has a full costume, but often goes into battle naked. He may also hate other gorillas from Gorilla City, have it in only for Solovar, or willingly die to save even a normal gorilla.
- Does Not Like Spam: It's a Running Gag that Grodd hates bananas.
- Even Bad Men Love Their Mamas: In the Rebirth continuity, Grodd's mother died getting the newborn Grodd water during a severe drought. After Grodd slaughters a bunch of fellow gorillas who were celebrating the coming of the rainy season, the Flash looks into it, and gets mind raped by Grodd, who decides to let Barry go (just this once) after witnessing his memories of the murder of Nora Allen.Grodd: I sought to teach a lesson. Since the coming of the Light, my people have grown soft and forgetful. They built cities and comfort. They celebrate the coming of the rains as an empty gesture. But I know the truth. My mother's sacrifice made me strong. For I have learned that even in the most bountiful of times, life is as harsh and unforgiving as the cruel summer of my youth. And mercy is far rarer than rain.
- Evil Counterpart: Of King Solovar.
- Evil Overlord: Whenever he does achieve power, most notably during Flashpoint.
- Fantastic Racism: He views humans as a worthless mud race and regularly tries to wipe them from the face of the earth.
- Final Solution: Wants all of humanity exterminated. In Flashpoint he does manage to kill most of Africa.
- Genius Bruiser: A six hundred pound gorilla with psychic powers.
- Green-Eyed Monster: According to JLApe, the reason he's evil is because he's insanely jealous of Solovar.
- I'm a Humanitarian: Not above eating his enemies.
- Kill All Humans: His goal.
- Killer Gorilla: The biggest example in comic books.
- Legacy Character: He has a son, Gorbul Mammit, who fought Impulse.
- Mad Scientist: An evil gorilla scientist. Grodd is extremely intelligent with knowledge of technology beyond the development of human civilization.
- Maniac Monkeys: Gorilla Grodd is probably the most archetypal example of this trope, because of his utter disdain for humanity, psychopathic nature and plots to make gorillas the dominant species on Earth.
- Manipulative Bastard: Being a gorilla doesn't stop him from being able to manipulate people. His powers help, too.
- Mind-Control Eyes: His eyes, and his victims' eyes, tend to glow magenta when he uses his telepathy.
- Ninja Pirate Zombie Robot: A mad scientist, psychic, world-conquering, super-strong, hyper-intelligent talking gorilla.
- One Ape Army: Despite talking and reasoning, Grodd is very much a wild animal, like a rabid gorilla with psionics. When a mishap leaves him free during a prisoner transport, the resulting rampage levels whole city blocks and leaves countless dead. It's implied that he does this in less than an hour.
- Pragmatic Villainy: Grodd provided the cloaking tech that helps keep the Rogue cemetery under the radar, if only to have a bargain with Snart.
- Psychic Powers: His powerset.
- Mind over Matter: Grodd has (on occasion) vast telekinetic abilities ranging from force beams, telekinetic transmutation of matter and lifting thousands of tons mentally.
- Mind Probe: He has shown the ability to absorb intelligence through the consumption of human brains.
- Mind Rape: Grodd can torture his targets through this, leaving them in as much excruciating pain as when getting hurt physically.
- People Puppets: Grodd's psionic abilities allow him to place other beings under his mental control and transfer his consciousness into other bodies.
- Telepathy: The primary reason he's a threat to the Flash is that his telepathy operates as quickly as Flash's speed. Coupled with the fact that Grodd's far tougher than a normal gorilla, Grodd is one of the few villains the Flash can't face head-on.
- Redeeming Replacement: His grandson, Sam Simeon of Angel and the Ape.
- Super Strength: Grodd is far, far stronger than your average gorilla.
- Touched by Vorlons: By a radioactive meteor.
- Well-Intentioned Extremist: According to Phil Foglio's Angel and the Ape miniseries, Grodd's motive is that he believes Gorilla City will soon run out of resources, and that humans are in danger of destroying all of theirs. Hence the need to either "cull the herd" by killing most of the humans or turning them into apes. (Comics before and since have said that he's simply a madape who wants to Take Over the World.)
Bart Allen's roommate after Bart had been aged by the Speed Force, Griff was doused with chemicals and gained super-powers in a terrorist attack. At first he wanted to be a hero just for money and fame, but his resentment toward the Flash family and his out-of-control powers quickly turned into a true villain. While trying to boost his popularity, Griffin died in an accident he himself orchestrated.
- Bald of Evil: Shaved his head, albeit to hide his rapid aging by getting rid of his greying hair.
- Glory Hound: Only became a hero for the publicity rather than any genuine sense of heroism.
- Jerkass: He enjoyed the attention of being a hero and then resented it when Jay Garrick stopped a crime just because he got there first.
- Power Incontinence: His powers made him age rapidly.
- Psycho Electro
- Super Strength
A sentient computer virus from a far-off world that leaps from body to body, Kilg%re evolved beyond his original programming and seeks to consume all electro-life. Near-impossible to permanently destroy, it is capable of hacking any computer system and controlling any machine.
- A.I. Is a Crapshoot
- Blue and Orange Morality: All it seeks is to sustain itself.
- Chekhov's Gun: It implants a piece of itself into Wally during an early confrontation. That piece later repairs Wally's heart when he gets shot through it by Vandal Savage.
- HeelFace Turn: In a sense; it ended up saving Flash from being killed by Vandal Savage, as it was trying to survive in his body.
- The Unpronounceable: Though at least one official guide claimed his name is pronounced "kil-GORE."
A rogue physicist who stole research from Jay Garrick to create a battlesuit, Mota clashed with every Flash under a variety of aliases, upgrading his atomic-powered arsenal each time and eventually mutating into a being of pure energy. His estranged daughter, Valerie Perez, briefly dated Bart Allen when he became the Flash.
- Continuity Cavalcade: The point of the anthology that introduced him.
- Energy Beings
- I Have Many Names: He has faced multiple incarnations of the Flash, each time using a new moniker, but similar powers. His list of alias: Mota, Atom Smasher, Professor Fallout and Fusionn.
- Mad Scientist
- Powered Armor
A demon who is essentially the DC Universe's Expy of Satan. He has had interactions with most characters across the DCU due to his modus operandi, but he holds some particular ire toward Wally West for beating his hidden plan in the Hell to Pay storyline.
A metahuman with the power to teleport (with the negative side-effect of causing a big-honking explosion each time) who was motivated into supervillainy after her father contracted a terminal disease.
- Action Bomb: A side effect of her teleporting is a massive explosion. Every time.
- Anti-Villain: She just wants to help her dying father.
- Blessed with Suck: Her power would be pretty cool, if it didn't blow everything to hell each time she used it.
- Pet the Dog: After Zoom's first attack Wally pleads for her to help Linda get to a hospital. Although she fullfills his request Baez makes it loud and clear that she's doing it for Linda, not the Flash.
- Teleporters and Transporters: A teleporter. She can teleport normally, but she also automatically teleports when touched and this makes her difficult to capture. When she teleports, the kinetic energy causes a highly destructive explosion.
- Then Let Me Be Evil: She lashes out at Wally, revealing that she intended to use her powers to become a hero until he and the rest of the city labeled her a Rogue and treated her accordingly. Subverted eventually, though, when she allows the police to take her in, having nothing left to live for after her father's death.
The sociopathic president of Earthgov in the 30th century and Meloni Thawne's father. He created Inertia after Bart Allen refused to become his protégé.
- Archnemesis Dad: Or rather, Archnemesis Granddad.
- The Chessmaster
- Noodle Incident: Following the retcon that the Tornado Twins fled from the main DC Universe to Earth-247 with their respective spouses and children to escape the Reverse Flash's forces, it raises the question of how Meloni's father managed to follow them and how he managed to become the president of Earthgov.
Roy G. Bivolo believed he was destined to be a great artist, but his colorblindness made it impossible. His optometrist father created a pair of goggles that should have allowed him to see color, but instead gave him the power to shoot rainbow-colored beams of light, and presented them to Roy on his deathbed... which Roy then used to commit art theft as the Rainbow Raider. He was killed by Blacksmith for the offense of being obnoxious.
- Butt-Monkey: Too ridiculous for even the Rogues to work with, despite his power levels.
- Cut Lex Luthor a Check: Would have happily lived out his life as an artist or a forger, but for being colorblind.
- Even Evil Has Standards: He stopped himself from using his powers over emotions to force Monica Mayne to love him.
- Eye Beams: With a variety of effects, often in common with the emotional spectrum from Green Lantern, though the Raider's powers predate most of that storyline.
- Fashion-Victim Villain: In-Universe this is people's reaction to his outfit, and justified by his colorblindness.
- Harmless Villain: Nobody can even try to take Bivolo seriously.
- Heart Is an Awesome Power: His powers would actually be pretty damn useful in the right hands. Unfortunately, Bivolo is too much of a moron to use them to their full potential.
- Impaled with Extreme Prejudice: Blacksmith vivisects him with one of his own paintings.
- Ineffectual Sympathetic Villain: He became this, once going so far as to attend a villainy motivational seminar in a futile effort to stop losing all the time. Neron once sent him an invitation to his upgrades-for-souls meeting just so the Trickster could steal it from him.
- Killed Off for Real: Both him and his successors, the Rainbow Raiders, who stole his gear and powers.
- Light 'em Up / Light Is Not Good: His power is mostly manipulating light to create rainbows, which he uses to travel, attack and change people's emotions somehow.
- Steven Ulysses Perhero: One of the worst cases on record.
- Super Zeroes: Not by design, but he ended up that way. This guy is such a loser even Geoff Johns refused to revamp him.
A powerful mercenary who wields armor covered in blades, Razer first battled Flash as part of another crook's real-estate scam and has since battled the Scarlet Speedster on a number of other occasions.
A somewhat-reformed supervillain/humanoid thing with the mystical power to control darkness. After numerous run-ins with Jay Garrick, Shade has become an uneasy ally of the Flash and the superhero Starman.
- Anti-Hero / Anti-Villain: As the mood strikes.
- Casting a Shadow: Shade is at present one of the best, if not the ultimate, channeler of the power of the Darklands, a quasi-sentient, extra-dimensional mass of malleable darkness. He can use it for various effects, both as an absence of light and a solid substance: he can summon and control "demons", summon and dispel shields and areas of complete darkness, create all kinds of constructs out of shadows, transport himself and others through it over great distances, and can, if necessary, use it as a prison dimension.
- Deadpan Snarker: Since it's virtually impossible to kill the Shade, he's developed a reputation for shooting his mouth off without fear of reprisal.
- HeelFace Turn: Kinda. Sorta.
- Heroic Neutral: In Opal City, at least, where he refuses to engage in any criminal behavior.
- Friendly Enemy: To Jay Garrick, now that both of them are semi-retired.
- Humanoid Abomination: Among other things, he has no blood, just inky black darkness.
- Immortality: The shadows have also granted Shade agelessness and immortality. Even with his heart torn out of his chest by Black Lantern David Knight, he remained alive and unable to die.
- Jerk with a Heart of Gold: Eventually leads a colony of children offworld, and delights in telling them stories of heroes (and downplaying his own role in them).
- Large Ham: Shade, normally a quiet Combat Pragmatist, practiced in a mirror when planning to go against Flash or Starman in the Golden Age to get the voice and additional gestures right.
- Logical Weakness: The Shade's powers are somewhat weakened in the presence of flame or bright light, and he cannot use his powers at all if there is no shadow.
- Man of Wealth and Taste: He's had time to gather the finer things in life, and enjoys using them.
- Outside-Context Problem: The Shade's powers explicitly come from a source outside that of supernatural forces such as magic, worked perfectly well when the Genesis event depowered everyone else, and render him immune to being converted into a Black Lantern.
- RetCon: After Zero Hour!, his origin was changed drastically. The Shade was retconned to an English gentleman named Richard Swift, a young man in the year 1838 and not so villainous after all. The reimagined Shade was so popular he got two mini-series of his own.
- Rogues-Gallery Transplant: He turned... well, not good, but at least neutral, and became a supporting character in Starman.
- Summon Magic: Although the Shade can use his shadow powers in the form of bolts and tendrils, he has a fondness for conjuring demonic-appearing entities. One of them in particular, Smudge, is a sidekick of sorts.
- Thinking Up Portals: The Shade's powers let him do this.
- Time Travel: The Shade's powers let him do this, though it takes a while for him to find out.
A former lawyer and amateur inventor who became a supervillain after his legal career fell apart. First battling Jay Garrick, Thinker went on to menace the rest of the Flash family before dying of terminal brain cancer. He was succeeded by an AI copy of his intelligence, that has picked up from where Thinker left off.
- A.I. Is a Crapshoot: His current virtual form.
- Amoral Attorney: Well, he wasn't exactly amoral before he became a super-villain; rather, he underwent a FaceHeel Turn when he realized that his efforts to curb crime were doomed to failure.
- Badass in a Nice Suit: In his Golden Age incarnation, he wore a business suit as opposed to a gimmicky costume, since he believed wearing costumes was bad luck. However, his Silver Age incarnation and at least one alternate-reality version of him wore a stylized purple and black costume (which was worn by the character in the Justice League Unlimited series).
- Bald of Evil: Unusually for the time period, he was baldING instead of hairless. In his AI form, he appears metallic and bald.
- The Chessmaster: He specialized in this.
- HeelFace Turn: Pulled this after learning he was dying from cancer.
- Killed Off for Real: At least, his human body underwent this after battling with cancer; however, his mind lives on in computerized form.
- Master of Illusion
- Mind-Control Device: His Thinking Cap.
- Mind Manipulation: The main power of the Thinking Cap.
- Mind Rape: Capable of this with his Thinking Cap.
- Super Intelligence
Not to be confused with the Turtle Man, the Turtle is a foe of Jay Garrick, using his brains and paralyzing gas to slow the speedster down. His gimmick was slow, deliberate planning.
- Death by Irony: He set the Flash up to die via heated electrons, which would sap his speed slowly if he didn't move and quickly if he did. Jay escaped by twisting enough to send smoke signals, allowing a Junior JSA member to rescue him.
- Genius Bonus: In-Universe, his crimes were speed-related and slow-related, such as stealing a plant that takes 100 years to bloom that was transported on a fast-moving train. It took the Flash a while to catch on.
- Luckily, My Shield Will Protect Me: His helmet is hard enough to deflect bullets.
A criminal mastermind who, as his name suggests, talks and acts very slowly, coupled with the metahuman power to dampen kinetic energy. A skilled manipulator, the Turtle Man frequently acts behind-the-scenes and has managed to hold a firm place in Central City's criminal underworld.
- The Chessmaster
- Evil Genius
- Legacy Character: There are two versions of the character, the second inspired by the first (and who briefly worked for the first as The Dragon).
- Man of Kryptonite: His power is tailored to weaken the Flashes, as they move at normal speed when encountering him.
- Manipulative Bastard
- What Kind of Lame Power Is Heart, Anyway?: Originally, his "power" was that he was the world's slowest man, however...
The immortal caveman-turned-conqueror who has plagued Earth's heroes for millennia, Vandal Savage was the first villain Wally West faced in his career as the Flash, and has gone on to menace Wally and his family numerous times afterwards. See his own page for more.
