Black Widow

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 Fiddler

Alter Ego: Isaac Bowin

First Appearance: All-Flash #32 (January, 1948)

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:
• Bald of Evil: Is bald as an egg, but wears a long white wig.
• 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.
• Green and Mean: His costume is green and he's a criminal.
• Instrument of Murder: Although primarily a Musical Assassin, Bowin would occasionally use gimmicked violins containing blades or guns.
• 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.
• Meaningful Name: Bowin, as in 'bowing'; i.e. playing a violin with a bow.
• Mind-Control Music: The Fiddler is a master hypnotist who can focus his abilities through his violin.
• Musical Assassin: His means of killing is with a special violin.
• Sesquipedalian Loquaciousness: Averted. Despite being a classically-trained musician and owning a Stradivarius, Bowin insists upon calling it a fiddle. Deadshot mocked him for this, asking specifically why, despite owning such a rare and expensive instrument and being an exceptional musician, he insisted in calling himself "Fiddler" like a common rube.

Golden Age Star Sapphire

First Appearance: All-Flash #32 (January, 1948)

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.

Midget Joe

Alter Ego: Joe

First Appearance: Flash Comics #45 (September, 1943)

Midget Joe is a gangster the size of a child who tries to use his size to pass as a baby or small child to fool the Flash on a few occasions.

• Mister Big: Midget Joe is a vicious gangster the size of a small child.

Rag Doll

Alter Ego: Peter Merkel

First Appearance: Flash Comics #36 (December, 1942)

A supervillain born with a rare ability, triple-jointedness, which enabled him to bend his arms and legs in astonishing ways.

• Abusive Parents: He has multiple children. He treated his son, Peter Jr., horribly because he wasn't born with the same triple-jointed capabilities and had extensive surgery to replicate it, while his daughter, Alex, he raped and sexually abused multiple times, leading to her committing self-mutilation and becoming the monster known as Junior.
• And Your Little Dog, Too!: Issue 11 of James Robinson's Starman comic showed that when he was confronted by Jay Garrick, Alan Scott, Ted Knight, Hourman, and Dr. Mid-Nite during his cult leader days, he threatened that his incarceration won't prevent him and his cult from endangering the lives of Jay Garrick's wife, Joan, Alan Scott's employees at the Gotham Broadcasting Company and Ted Knight's two sons, David and Jack.
• Contortionist: Rag Doll is naturally triple-jointed, which allows him extreme flexibility, as well as durability and some elasticity.
• Cult: At one point, the increasingly senile Rag Doll, in extreme pain due to the deterioration of his body, begins ranting and wandering the streets. He soon finds himself the leader of a cult of the disenfranchised.
• Deal with the Devil: The aging Merkel sold his soul to Neron in exchange for having his youth and physical prowess restored.
• Dodge the Bullet: In his prime, Merkel was fast and flexible enough to dodge bullets.
• Fountain of Youth: Had his youth restored by the demon Neron.
• From Nobody to Nightmare: He started off as a fairly goofy yet standard villain. Then, as he got older and grew senile, he amassed followers listening to his rants until he formed a cult that terrorized America. Then, he sold his soul to Neron to regain his lost youth. And during all of that he'd been abusing his children in every sense possible, especially his daughter, Alex, who "was his favorite."
• Monster Clown: Depending on the Artist some modern artists draw Merkel's costume to look more like a clown than a rag doll.
• Parental Favoritism: Twisted in regards to his children. His son,Peter Jr., was The Un-Favorite because he didn't naturally inherit his dad's triple-jointed capabilities. His daughter, Alex, was his favorite, which he demonstrated by sexually abusing her until it drove her insane.
• Parental Incest: Was fond of raping his daughter, Alex, over and over again to the point her mind completely shattered.

The Shade

Alter Ego: Richard Swift

First Appearance: Flash Comics #33 (September, 1942)

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.

The Turtle

Alter Ego: Unknown

First Appearance: All-Flash #21 (December, 1945)

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.

• Bad Future: Year Zero has him create one where he takes over Central City, sapping speed from people or forcing them to serve him as mooks. Barry manages to prevent it from happening.
• Composite Character: His Rebirth incarnation is a mix of him and the Turtle Man, having the Turtle's looks and outfit mixed with Turtle Man's M.O. and powers.
• 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.
• Even Evil Has Loved Ones: Subverted. His family tried to support him after his Still Force related accident, and stuck around. Then he killed them, believing love was holding him back.
• Evil Counterpart: Year Zero makes him another villainous foil to Barry. Where Barry unintentionally drives away his loved ones via poor decision making, the Turtle just killed his for the sake of power. And their powers directly contrast one another, with the Turtle using the power of the Still Force to slow things down.
• 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.
• Master of Motion: The Rebirth era reinvents the Turtle as a conduit of the Still Force, a cosmic force based around entropy and inertia. As the name implies, this force is the opposite of the Speed Force and those who channel its power can negate any and all forms of motion.
• Only Known by Their Nickname: Despite being one of the oldest known villains of the Flash, his true name has never been revealed.
• Starter Villain: In the Rebirth continuity, he's Barry's first villain.
• Verbal Tic: Talks...very...slowly...unless he's got enough of someone else's speed energy fuelling him.

The Thinker

Alter Ego: Clifford DeVoe

First Appearance: All-Flash #12 (September, 1943)

A lawyer who decided to turn to crime after his career flopped, using his intellect and legal expertise to become the brains behind other criminals, many of them former clients. He was the creator of the Thinking Cap, a high-tech helmet that allowed him to focus his mental energies into physical force, which would unfortunately become his downfall.

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 Face–Heel 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 series).
• Bald of Evil: Unusually for the time period, he was balding instead of hairless. In his AI form, he appears metallic and bald.
• Big Bad Ensemble: He opposes Blacksmith and the Network while he enacts his own plans during Crossfire.
• Brain Uploading: Mr. Terrific accidentally did this when he used The Thinkers Thinking Cap to create an AI for the JSA's new computer system, which quickly gained sentience as the Cap contained the original Thinkers brain patterns. This AI Thinker went on to join Johnny Sorrow's Injustice Society.
• The Chessmaster: He specialized in this.
• Friendly Enemy: Apparently became this sometime after the Golden Age passed, where he and Jay Garrick became friends, to the point Jay stood by him to help him through his cancer treatment, and went to extreme lengths to try and help him live.
• Heel–Face Turn: Pulled this after learning he was dying from cancer.
  • Face–Heel Turn: After his code-form was imprisoned by Checkmate, he decided to help them.
• Hoist by His Own Petard: The Thinking Cap had the rather severe drawback of causing cancer after decades of use, resulting in his death.
• Killed Off for Real: At least, his human body underwent this after battling with cancer; however, his mind lives on in computerized form.
• Legacy Character: There have been two other Thinkers, Clifford Carmichael and Desmond Carter, but neither appear to have been related to the original other than In Name Only.
• The Man Behind the Man: Styled himself as this trope, rather than being the actual leader of the gangs he made plans for, he was more of a consultant.
• Master of Illusion: He can pull this off thanks to the Thinking Cap.
• 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: Once again, thanks to the Thinking Cap.
• Sympathy for the Devil: Spends his final mortal moments accompanied by a distraught Jay.
• Terrible Trio: With Fiddler and The Shade during the Flash Of Two Worlds storyarc that introduced the DC multiverse and reintroduced Jay Garrick.

• Back from the Dead: Although killed off in the pages of Suicide Squad, Big Sir has reappeared post-Flashpoint.
• Dumb Muscle: Was chosen by the Rogues precisely because of his combination of strength and lack of intelligence.
• Enhanced Archaic Weapon: Uses an energy mace that also allows him to fly.

• Nigh-Invulnerability: Ramsey claims he is invulnerable, as it is very difficult to hurt him.

Brother Grimm

Alter Ego: Grimm

First Appearance: The Flash Vol 2 #166 (November, 2000)

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.

• The Evil Prince: He actually started out as the good prince, but a chain of events led him down a dark path and he blames Wally for his troubles.
• Evil Sorcerer: Wields powerful magic to help him counter the Speed Force and is definitely a villain.

• Mage in Manhattan: Can conjure up dragons, trolls, giant beanstalks, and other fairy tale monsters and props.

• Pointy Ears: He has pale green skin and pointy elven ears in his later appearances.
• Refugee from TV Land: The king of the fairy tale land of Eastwind.
• Remember the New Guy?: In Grimm’s debut story, Wally explains that he first met Grimm in an unseen adventure a long time ago, back when he was still Kid Flash instead of the Flash. So, Wally’s already familiar with Grimm, even though the readers won’t be.
• Revenge: Accuses Wally West of ruining his relationship with his father and brother and causing their deaths.
• Sensor Character: Can detect other-dimensional energies such as the Speed Force, allowing him to hit and dodge speedsters despite not having superspeed himself.

• Sibling Murder: With his father, Nightingale, deposed, the people ask Grimm to be their king. Uninterested in ruling, Grimm takes Kid Flash's advice to "follow his path" and lets his brother take the crown.

Alter Ego: Serina Grant

First Appearance: The Flash Vol 2 #36 (March, 1990

• Bitch in Sheep's Clothing: Advertises herself as a humble, enlightened good Samaritan who wants to teach others a better way of life. When the camera's off, she's a smug, materialistic con artist who doesn't believe any of what she preaches and only cares about her clients' money.
• Church of Happyology: The Center Celia runs advocates long meditations, special diets, and contacting dead spirits, along with using celebrity spokesmen like the Flash. It's pretty blatantly a riff on Scientology.
• Fake Ultimate Hero: She summons Llar-Twnakc to vanquish an attacking terrorist group, leaving Wally insecure about his hero status. Of course the terrorists were Celia's goons and the event was staged to plant insecurity in Flash's mind, drawing him into the Center's fold.
• Manipulative Bitch: She successfully dupes the Flash into joining the Center and serving as it's spokesman for a while. Then again, Wally is easily led astray by appealing to his need for guidance.
• Mundanger: Outside of the theatrical way she sets out her scam, this woman is neither a flamboyantly-dressed high-tech thief, a psychic gorilla warlord, or an evil Speedster. She's just a scummy con-artist who preys on the easily swayed, something that definitely happens outside comic books.
• Phony Psychic: Her ability to channel spirits is a load of hooey, as Linda pieces together quite quickly.
• "Scooby-Doo" Hoax: The spirit of Llar-Twnakc, actually a lifelike holographic projection. She also pulls this with calling forth Wally's late father during a Seance... who, for his part, is secretly alive and working with Mc Grath in her con.
• Willing Channeler: Is seemingly one for a powerful Atlantean spirit. Of course it's all special effects.
• Villain of the Week: Was the main antagonist of one four-issue storyline, got busted, and hasn't been seen or heard from since.

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.

• Evil Old Folks: An older man with a white beard and definitely a villain.

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.

• Misplaced Retribution: Malcolm wants revenge on Barry for getting a much better life for him, even though Barry had nothing to do with the doctor who delivered them stealing Malcolm and giving him to the Thawnes.
• 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.

First Appearance: The Flash: Iron Heights (October, 2001)

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.
• Living Battery: His powers are used to keep Iron Heights running.
• Meaningful Name: He's named after Niels Bohr, one of the contributors to the Manhattan Project.
• Power Glows: His body glows green with radioactivity.
• 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.

Folded Man

Alter Ego: Edwin Gauss

First Appearance: The Flash Vol 2 #153 (October, 1999)

Edwin Gauss was a physics student at M.I.T. looking to definitively prove Albert Einstein's Unified field theory. After feverish effort, which included the theft of software from electronics billionaire Norman Bridges, Gauss invents a method of interdimensional travel. He developed an exoskeleton which allows his physical form to move across at least four dimensions seamlessly. Bridges, who considers the exoskeleton Gauss developed (using Bridges own software) to be his own property, pursues Gauss to claim the technology for himself. Gauss reinvents himself as a costumed criminal named "the Folded Man".

• Affirmative-Action Legacy: For a time the Folded Man was succeeded by an African man named Xolani, who was part of the Acolytes of Zoom, although eventually Edwin Gauss returned.
• Paper People: In his 2-D form he is totally flat, isn't solid (hence, can't be hit) and is invisible when seen from sides.
• Teleportation: Gauss within his exoskeleton was capable of teleporting anywhere within the 3rd dimension by shifting to the 4th, allowing him to seemingly disappear from reality altogether when in actuality he was merely crossing from one dimension to the other.
• Thinking Up Portals: Can open portals at will, attacking enemies without early warning.

Gemini

Alter Ego: Santiago and Belladonna

First Appearance: The Flash Vol 5 #58 (January, 2019)

The pair known as Gemini are two lovers named Santiago and Belladonna who are obsessed with absorbing power and making it their own.

• Energy Absorption: Gemini absorb energy from others and make it their own.
• One-Steve Limit: Share their alias with a Batgirl villain.
• Outlaw Couple: A supervillain duo who are also lovers.

Gorilla Grodd

Alter Ego: Grodd

First Appearance: The Flash #106 (May, 1959)

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 (or deliberately by an alien, Pre-Crisis) along with the other apes of Gorilla City, but also gained vast telepathic and telekinetic powers; there are only a single-digit number psionicists on DC Earth more powerful than Grodd, and he's more skilled than they are at leveraging his powers. He even eclipses the Martian Manhunter in psychic power. Grodd is also a genius scientist and an absolutely enormous silverback gorilla who's not at all afraid to wade into a fight. His biggest weakness is that occasionally his animal rage eclipses his intellect. He originally clashed with Barry Allen and has gone on to menace the entire Flash family.

While he's a Flash foe at heart, Grodd is considered a Justice League-tier global threat all on his own due to his triple-threat combination of brains, brawn, and psychic power, and he's proved it's a correct assessment many, many times. When DC's biggest bads unite into an iteration of the Legion of Doom, he's the most common representative of the Flash's rogues, and he's the second most likely villain to be leading the team after Lex Luthor. Even when Lex is in charge, Grodd is invariably part of the Legion's inner circle (they're often rivals for just this reason. Lex dismisses Grodd as a brute beast with pretensions of intellect, and to Grodd Lex is a smart human, but he's still a human).

• Adaptational Nice Guy: Works such as Justice League and LEGO DC Super-Villains depict him as being perfectly amiable towards other villains and even sincerely thanks them for help. Comic Grodd is too self-serving and Ax-Crazy to even fake that.
• Adaptational Sympathy: More recent iterations of the character portray Grodd as a ruthless, yet at times noble beast who genuinely does care for his kind. In the "Black Hole" arc, even Barry tries to help him when he's dying, even as Grodd is pillaging the Speed Force to save himself. Even his defeat is played pitifully, as when Barry does take his power back, Grodd despairs and prepares to die before he's taken into custody by Gorilla City authorities.
• Ambition Is Evil: Grodd's motivations are borne from a mix of rabid hatred for the humans he sees as dominating the planet, envy of Solovar, and lust to become more than just another gorilla.
• Animal Is the New Man: One of Grodd's most consistent goals is to replace humanity with gorillas as the Earth's dominant species. In JLApe he orchestrates a plan to transform people into apes, and actually succeeds in transforming the Justice League themselves.
• Arch-Enemy:
  • To Barry Allen during the Silver Age, when Grodd 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, and Eobard Thawne has largely taken his place as the worst of Barry's opponents, but he still hates the Flash family with a burning passion.
  • Even other seriously antagonistic Flash rogues like Blacksmith can't hold a candle to Grodd. Even Abra Kadabra, who considers Grodd a friend, will beat it when Grodd is well and truly angry.
  • He and King Solovar are almost always at each other's throats, even in continuities like the Injustice-verse that reduce Solovar's sympathetic qualities. It seems to be a universal constant.
• 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 had licence to keep appearing by being frequently updated to fit the tone of the times.
• Ascended to Carnivorism: Has been known to eat humans. Real Gorillas are almost entirely herbivorous, at most eating the occasional stick-full of termites to help with diarrhea.
• Ax-Crazy: Don't let his intellect fool you, Grodd is still a savage, bloodthirsty animal.
• Berserk Button: Do NOT call him a monkey unless you really want to make him mad. Don't make jokes about bananas, either.
• Big Bad: Of JLApe and the 1991 Angel and the Ape miniseries. In the Justice League animated series, he was a member of the Big Bad Ensemble.
• Brain Food: In his more modern incarnations, he developed a gruesome taste for his enemies' brains. The New 52 version even ate the brain of his own father.
• Call an Ape a "Monkey": He is a gorilla, and he will try to maim anyone who calls him a "monkey".
• Cannibalism Superpower: Eating brains can allow him to absorb their knowledge, and sometimes powers like the Speed Force.
• The Chessmaster: Grodd can absolutely play the long game when it suits him. His DCAU incarnation is especially skilled at manipulating friend and foe alike, at one point bringing the Justice League to breaking point by using his Psychic Powers to enhance their feelings of discord and distrust against each other.
• Depending on the Writer:
  • Grodd sometimes has a full costume; other times he goes into battle with only his fur.
  • He may also hate other gorillas from Gorilla City, have it in only for Solovar, or willingly die to save even a normal gorilla.
  • Different media also focus on which powers and abilities that makes him a threat. Sometimes he's most dangerous for his brute strength, other times it's his Psychic Powers, other times it's his cunning intellect and/or skill for manipulation.
• Does Not Like Spam: It's a Running Gag that Grodd hates bananas.
• The Dreaded: Is almost in the same rank as any of the Reverse-Flashes in sending fear to speedsters (and in the rest of the superhero community in general).
• Even Bad Men Love Their Mamas: In the Rebirth continuity^note DC's Beach Blanket Bad Guys Special #1, 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.
• Even Evil Has Standards: Believe it or not, at times Grodd does seem to care for his home of Gorilla City. During Judd Winick's Outsiders, he went along with the Joker's plan to kill Lex Luthor to get a cure for the plague threatening his people. When the Outsiders almost drowned a bunch of his troops, Grodd was horrified and begged them not to cause any more death.
• 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.
• Fork Fencing: To supplement his brain eating, he carries around a giant spoon to scoop brains out with.
• Freudian Excuse: The Rebirth continuity actually does explore this. As a baby gorilla, Grodd was small and sickly. He was treated as the runt of the troop, and eventually his mother died protecting him during a drought. Naturally that baby grew up and decided to become a force who would never be weak again.
• From Nobody to Nightmare: Big time. Grodd was originally one of several nameless gorillas who happened to stumble upon a bizarre otherworldly artifact that drastically increased their intelligence. Grodd developed telepathy, as well as a dangerously ambitious streak, and went on to become one of the DCU's most prominent threats.
• Genius Bruiser: A six-hundred pound gorilla with a high-level intellect and the verbiage to match it.
• A God Am I: In JLApe: Gorilla Warfare. "I am the Lord thy Grodd! All shall bow before me!"
• Green-Eyed Monster: According to JLApe, one of the reasons he's evil is because he's insanely jealous of Solovar.
• A Hero to His Hometown: Downplayed. Grodd is still regarded as a criminal in Gorilla City but he also has plenty of fellow apes who support his vision and aid in his plans for conquest. At times he's called upon as a military strategist, and even Solovar notes Grodd would be useful in the event of a war with humanity.
• I Just Want to Be Loved: In JLApe, Martian Manhunter deduces that Grodd's real motivation is to be adored by his people the same way Solovar was. In Williamson's Flash run, he admits to Barry that he would kill for the kind of family the Flash has.
• Innocence Lost: The first time Wally saw an innocent person die as Kid Flash, it was at Grodd's hands. Now whenever Wally has to fight Grodd alone, he's fighting his fear of Grodd along with the big ape himself.
  • Paradoxically, Wally's son, Jai, was able to stop Grodd from attacking him just by asking him a question. The question? Why does Grodd do all the terrible things he does? The question surprised Grodd so much he snapped out of a full on rage and gave Jai an honest answer, because no one had ever bothered to ask him what his motives were before.
  Jai: Uh. Hi. Uh. I've always wondered. Why do you do what you do?
  Grodd: Hm. All the costumed ideologies. All the bloodshed. Nobody's ever asked. I am Mwenye! I am the father-possessor! I am silverback! Difficult for you sapiens to understand what that means. My troop— my family. They are my breath— but I am not their lord. I am their slave. Sometimes I cannot bear the burden of their hopes for prosperity. But I must. Because nothing I do... not the wounds I suffer nor the bargains I strike... none of it is too great a price— to build a world of choices for my children. Such should be the priority of any responsible father.
• It's Personal:
  • Not as personal as say, Barry's feud with Eobard Thawne, but things between him and Grodd are still pretty personal.
  • Wally West also has a large bone to pick with Grodd after he maimed Hunter Zolomon. It was one of the few occasions where Wally actually has a killing intent.
  • Not that Grodd has any love for Barry, but he hates Wally. Even when he had no memory of Wally whatsover, just seeing him was like an infuriating itch in the back of his mind.
• Kill All Humans: One of his main goals is to enslave and/or wipe out all of mankind.
• Killer Gorilla: Despite talking and reasoning, Grodd is very much a wild animal, like a rabid gorilla with psionics.
• 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.
• My Species Doth Protest Too Much: The apes of Gorilla City are generally peaceful isolationists who prefer to live away from humankind. Unfortunately, Grodd, the most famous of them, is a brutal megalomaniac who's not satisfied with a peaceful existence.
• Ninja Pirate Zombie Robot: A psychic, world-conquering, super-strong, hyper-intelligent talking Mad Scientist Killer Gorilla.
• One-Man Army: Oftentimes, Grodd is capable of doing massive amounts of damage all on his own. 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.
• Pet the Dog: Grodd actually attended the funeral of Captain Boomerang, and didn’t cause any trouble.
• 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.
• Psychopathic Manchild: Grodd has an incredibly short temper and tends to fixate on his childish rivalry with Solovar and the Flash. In short, he is what happens when you give an already maladjusted animal higher brain functions and unchecked power.
• Redeeming Replacement: His grandson, Sam Simeon, of Angel and the Ape.
• Super-Strength: Grodd is far, far stronger than your average gorilla.
• To Serve Man: Not above eating his enemies.
• Touched by Vorlons: Pre-Crisis, he and the rest of Gorilla City were granted sentience and the ability to talk by an alien. He and Solovar also got their Psychic Powers. Post-Crisis, it was the result of a radioactive meteor.
• Ungrateful Bastard: In his pre-Crisis origin, Grodd was granted his vast mental powers by an alien explorer. He thanked his "creator" by arranging his murder to convince Gorilla City that humans were barbaric. And he only got worse from there.
• Unwitting Instigator of Doom: His crippling of Hunter Zolomon was the last straw that would lead him to become Zoom, meaning that he has a part of responsability for the man's own crimes.
• Uplifted Animal: Grodd and the other inhabitants of Gorilla City were evolved from simple apes into super-simians.
• Victory Is Boring: In Flashpoint, Grodd has conquered all of Africa, and is actually disappointed that there was no one to stop him, and even wants to dip into the Amazon-Atlantis war just to alleviate his boredom.
• 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).

Alter Ego: Griffin Grey

First Appearance: The Flash: The Fastest Man Alive (2006) #1 (August, 2006)

Bart Allen's roommate after Bart had been aged by the Speed Force, Griffin was doused with chemicals and gained superpowers in a terrorist attack. At first he wanted to be a hero just for the money and fame, but his resentment toward the Flash family and his out-of-control powers (which caused him to become aggressive and paranoid) quickly turned him into a villain. While trying to boost his popularity, Griffin died trying to stop an accident he himself orchestrated.

• Psycho Electro: He gets the power to shoot teal-colored lighting bolts out of his hands.

A criminal in Central City with the ability to control wood, which he usually uses in conjunction with razor-sharp paper.

• Alliterative Name: Benedict Booker
• Meaningful Name: A man with the ability to control paper named Booker.
• Paper Master: Can manipulate wood, though he has a harder time manipulating actual wood than paper and other derivative products. His skill with said ability is such that he can even manipulate other plant based elements besides, such as the cotton & linen in dollar bills, using them as projectiles against the Flash.
• Psychic Nosebleed: If he uses his powers on actual wood, he gets a nosebleed.

Paradox

Alter Ego: Chris

First Appearance: The Flash Vol 5 #50 (September, 2018)

Once an ordinary family man in Central City, Paradox was a scientist who believed in the constant shifting nature of the multiverse, a theory proven right on the day Barry Allen was struck by lightning. A fight between the Flash and the Turtle caused him to get sucked into another dimension, where he found mysterious tech, which he used to observe the Flash across history... and came to the conclusion that the Flash needs to die.

• Blessed with Suck: Paradox is sensitive to every change the multiverse goes through, and it hurts him. A lot.
• Evil Makes You Ugly: The energies he was exposed to turned him from an ordinary looking guy into a large, hulking monstrosity.
• Evil Versus Evil: The Reverse-Flash thought this guy was a threat and sealed him away in Iron Heights. Yep, compared to this guy, Eobard Thawne managed to be the hero.
• From Nobody to Nightmare: Once, he was a regular guy. Now he's one of the most dangerous beings in the multiverse, capable of erasing people from existence with a thought.
• Godhood Seeker: His ultimate end goal is to absorb the energy released by the various Crises and become a god.
• He Who Must Not Be Seen: He first appears at the end of "Flash War", in The Flash #50, as a silhouette, then a partial shot in Flash annual no. 2. It's not until The Flash #88 that we see him in full, though that issue reveals he'd shown up several times through "Year One" in his civilian form.
• Leaning on the Fourth Wall: A lot of his rant while he's beating up Barry sound a lot like what some fans have said of Barry since his resurrection in Final Crisis.
• Motive Decay: His initial motivation was just to get back to his family. When that proved impossible, he decided to conquer the 25th century. After that, and a long stay in Iron Heights, he decided instead to kill all Flashes.
• Never My Fault: He tricks three people who got sucked into that other dimension with him into getting themselves killed, then immediately blames the Flash for it.
• Ret-Gone: He's seemingly defeated for good when Eobard travels back in time and prevents Chris from falling into the dimensional portal, stopping him from ever becoming Paradox.
• Timey-Wimey Ball: He draws power from invoking time paradoxes, the more paradoxical the better. He gets moderate energy killing Flash multiple times, but gets a huge boost killing his own past self.
• With Great Power Comes Great Insanity: Chris didn't seem to be entirely stable to begin with, having an obsessive need to investigate other realities, but he was a nice guy and loving family man. Getting zapped into another dimension caused him to start going completely insane.

Peek-a-Boo

Alter Ego: Lashawn Baez

First Appearance: The Flash Vol 2 #180 (January, 2002)

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.
• Flashy Teleportation: When she teleports, the kinetic energy causes a highly destructive explosion. She can teleport normally, but she also automatically teleports when touched and this makes her difficult to capture.
• Pet the Dog: Wally pleads for her to help Linda get to a hospital after an explosion of her own doing. Although she fulfills his request, Baez makes it loud and clear that she's doing it for Linda, not the Flash.
• 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.

Alter Ego: Thaddeus Thawne

First Appearance: Impulse #25 (May, 1997)

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.

• Alliterative Name: Thaddeus Thawne.
• Archnemesis Dad: Or rather, Archnemesis Grandfather.
• Continuity Snarl: He was supposed to be the president of Earthgov in the 30th Century despite the fact that over in the Legion of Super-Heroes titles published at the same time, Earthgov's president at that time was Jean Chu (later replaced by R.J. Brande). Making things even more confusing was the knowledge Thawne wasn't native to Earth-247, making it difficult to figure out how and when he was president.
  • It was alluded to that Chu was one of President Thawne's direct subordinates at the time of his administration. She directly succeeded him. Given the kind of people they both were, she likely betrayed him and used his downfall to attain the Presidency.
• 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.

He has a different origin and motivation, however, and is treated as a much smaller threat than Savitar was.
