The Golden Age Flash enemies were all villains of the first Flash, Jay Garrick, later portrayed as living on Earth-Two after the introduction of the Silver Age Flash.
In chronological order (with issue and date of first appearance):
| Villain | First appearance | Description |

| Rag Doll | Flash Comics #36 (December 1942) | Peter Merkel was born "triple-jointed", which enabled him to flex farther than any other human being. He hid in a rag doll costume and robbed stores. Has recently died, but has had several children, a few of whom are also Ragdolls, including a daughter who is also a villain, a son that is a member of the Secret Six, and another yet to be revealed son mentioned by his brother. His death in JLA Classified #7 was later undone by the events of Flashpoint, and he has since been a member of the Legion of Zoom to fight against the Flash after the Reverse-Flash took him from the past, before he died in Suicide Squad Annual #1 by ghosts. |
| Eel | Comic Cavalcade #3 (June 1943) | “Eel” Madden was a criminal who had a grease gun, which made it almost impossible for anyone to catch him. |
| Thinker | All-Flash #12 (September 1943) | Clifford DeVoe, a former DA, was a villain who used a specially designed "thinking cap" as an aid in conjuring up and performing various crimes, and a founding member of the Injustice Society of the World, in which position he captured the Flash. He later became friends with the Flash before dying from cancer; however, his Thinking Cap technology had become a computer program that made itself into a villain that battled Wally West and the rest of the JSA. The Thinker AI joined Johnny Sorrow's more modern Injustice Society and Checkmate before the events of Flashpoint. After Flashpoint the Thinker AI was taken out of the past to join the Legion of Zoom. He returned to his own time after the team was overpowered by the Flash Family. |
| Turtle | All-Flash #21 (January/February 1946) | A villain who used slowness-related weapons against the Flash, was inactive for a long time, then reappeared and now has the power to take away speed from people. After disappearing for a long time after fighting Jay Garrick in the 1940s, the Turtle wanted to set up an empire in Keystone City. He worked with Turtle Man, one of Barry Allen's villains, and his henchmen (Mr. Sloe, Mr. Steddy and Mr. Sprynt) in an attempt to establish his empire, but Wally West defeated the Turtle's henchmen. The Turtle trapped Wally when he released an ultrasound trap in a warehouse, but when Wally's friends rescued him Turtle detonated the building. Wally and his friends escaped the building in time, but the Turtle was left in the building. Whether he survived or died is unknown. Turtle has since been shown after the events of Flashpoint. In the new timeline, he had a high intellect and graduated from school. Later in his life, he got married and had two children, and spent a lot of time with his family. This led to his scientific advancements being slowed and Turtle growing jealous of more successful scientists. He rushed experiments in an effort to show his intellect again, but was caught in an explosion with the Still Force and had his age accelerated, making him an old man. He later discovered that he could nullify any form of motion, including the progression of life. While he continued to experiment with the Still Force, he became disappointed with life as he knew he would outlive everyone he loved. This caused him to murder his family with his powers, as he saw them as distractions from his scientific work. |

In the early 1940s, Razar ran a small mob that was taken over by gangster Topper Hull. Hull framed Razar and had sent him to prison. In the summer of 1947, Razar hatched a plan to escape by sabotaging the prison power generator. His plan had an unforeseen side effect, charging Razar with enormous amounts of electricity and giving him the ability to change into different animals. Razar used his new powers to escape and set out in pursuit of Hull. Disguised as a bird, Razar learns that Hull has planned a bank job by intercepting an armored car delivery. Razar decided to torture Hull by thwarting his crimes and intercepted the car first. By this point, the police had consulted with scientist Jay Garrick who was among those who witnessed Razar, as a large bull elephant, intercept and dismantle the armored car. Quickly changing to the Flash, Garrick engaged the shape-shifting criminal, but was quickly dispatched into a large water reservoir. Razar, now named the Changeling by the local papers, decided to foil Hull's hijack of a sunken ship recovery operation and then kill him. The Flash also became aware of Hull's plans by eavesdropping in his invisible super-speeding form and determined to intercept them both. Razar dove into the water as Hull's boat left the pier and transformed himself into a large shark. The Flash dived in behind the Changeling, but the criminal irritated a large clam which seized the Flash's leg and threatened to drown him. After extricating himself, he came upon the Changeling-shark threatening the divers in the recovery operation and assaulted him. Deciding that he would need to kill the villain to stop him, the Flash battered the shark's gills until it could not breathe and then knocked it unconscious as the Changeling tried to change forms. As the unconscious and unmoving shark drifted to the bottom, the Flash left to capture Hull. (Flash Comics #84) Whether or not the Changeling survived has never been determined. |

While in high school Rose developed another personality called Thorn and blackmailed a paedophile for information on her father's death. |
| Fiddler | All Flash Comics #32 (January 1948) | Isaac Bowin was a villain who used a violin to perform crimes, usually by using the violin to hypnotize people or cause vibrations which could shatter objects after learning skills from a fakir he was in prison with, before murdering him. He first tried to frame his brother, but was defeated and pretended to commit suicide. Later he resurfaced. Recently, he joined the Secret Six, but when he failed a mission, he was killed by Deadshot on the orders of their leader, Mockingbird.

He is now pure energy from the Speed Force. He joined Johnny Sorrow's Injustice Society and committed numerous murders which spelt out his name, but he was defeated by the Flash before he could murder Joan. |

## Silver Age

The Silver Age Flash enemies all lived on Earth-One and started out as enemies of the second Flash, Barry Allen, as well as the third Flash, Wally West, and the fourth, Bart Allen, after the death of Barry Allen. The Silver Age is when some enemies started to use the name "Rogues". Originally, the Rogues were just a few of the Flash's enemies teaming together, but since then they have formed a lasting team, and usually a Rogue will not commit a crime by himself. The original eight Rogues were Captain Cold, the Mirror Master, Heat Wave, the Weather Wizard, the Trickster, the Pied Piper, the Top, and Captain Boomerang. The current incarnation of the Rogues includes Captain Cold, the Weather Wizard, Heat Wave, the third Mirror Master, and the second Trickster.
In chronological order (with issue and date of first appearance):
| Villain | First appearance | Description |
| Mazdan | Showcase #4 (October 1956) | A criminal from the 38th century, who the authorities decide to exile to the 50th century when Earth is desolate. He is accidentally sent to the 20th century and tries to steal equipment needed to repair his time capsule, such as gold to coat it, and get back to the future to exact revenge, using advanced heat-based weapons. The Flash discovers this and captures Mazdan, who escapes using a contact lens that fires lasers and a "magnetic rod" that focuses heat; the Flash discovers that if Mazdan escapes using his time capsule, it will destroy everything within a radius of at least 10 miles, killing thousands. He uses his super-speed to break through the time barrier with Mazdan, who, oddly enough, does not die from the friction and returns to the 38th century. The authorities say they will make sure next time the time capsule reaches the 50th century and the Flash returns to his own time. Mazdan later escapes to the 20th century again and uses a mind-affecting hallucinatory weapon to cause trouble for the Flash, but is beaten again and returned to prison in the 38th century. |
| Captain Cold | Showcase #8 (June 1957) | Leonard "Len" Snart was a criminal who wanted a chance to get rid of the Flash. Seeing an article about a weapon that might disrupt the Flash's speed, Snart made a gun and exposed it to radiations. However, due to the fact Snart was not experienced in the use of the device and activated it incorrectly, instead of slowing the Flash down, the gun could freeze anything to absolute zero, which he discovered when he accidentally used it on a watchman. Calling himself Captain Cold, Snart started out on a criminal career. He is the leader of the Rogues. Known for being a sympathetic villain, Cold has a sense of honor. Cold has strict rules on how the Rogues should act, such as no drugs and not to kill unless they have to. He also has a sense of loyalty to his team and watches out for them. |
| Doctor Alchemy | Showcase #14 (June 1958) | Albert Desmond suffered from a split personality, one a good person and the other evil. Originally calling himself Mr. Element and using element-themed devices before being captured by the Flash, he changed it to Dr. Alchemy when he found the Philosopher's Stone, which could transmute elements after hearing of it from a cellmate, and was able to transmute elements, although the effects only lasted for about 20 minutes.

| Top | The Flash #122 (August 1961) | Roscoe Dillon used many top-themed weapons to commit crimes, eventually learning how to spin himself at great speeds, increasing his intelligence and allowing him to deflect bullets. Although he died, Dillon's mind was so powerful that it took over the minds of many people to keep on living, including Henry Allen and a senator, whose body was reformed by Dillon to look like his original body. He was later killed again by Captain Cold when Dillon tried to take over the Rogues during the Rogue War.

Once just a simple villain, he became more well-known when he killed Barry Allen's wife Iris Allen (although her consciousness was transported to the 30th century at the last possible instant). This action made him Barry Allen's arch-nemesis. Later, when Barry was about to marry Fiona Webb, Thawne tried to kill her but, in a fit of rage, Barry killed him by breaking his neck, thus putting the Flash on trial for murder, where he was found guilty. He was returned to life and was the one behind Flashpoint. |

Unfortunately, Borman had brought his wife and son to work to show them around the plant. Contact with his new body killed them, and in the same way he inadvertently killed several people. Genuinely remorseful, he was imprisoned in Iron Heights Penitentiary, where he was used to power the prison with his new abilities.

Hunter got very mad at the Flash, and decided to try to do it himself. However, the Cosmic Treadmill exploded during the process, and Hunter gained superspeed not coming from the Speed Force, but from time itself, making him even faster than the Flash. Zolomon set out to make the Flash a better hero by letting him deal with loss, and killed his unborn twins. This event has since been rectified due to time travel.

Initially, the duplicates worked with Manuel in his "one-man" crusade against Basilisk. When they began to die for no reason in the same order in which they were "born", their new mission became to find a doctor who can find a cure so they could continue to live. Members of Mob Rule all identify each other by numbers based on the order in which they were "born". After encountering Mob Rule trying to steal a human genome re-coder, Barry Allen identifies his old friend Manuel Lago as one of the thieves. Later the next night, Manuel breaks into Barry's apartment being chased by Mob Rule, so Barry follows his friend. When Barry catches up with Manuel, he finds his old friend surrounded by copies of himself. The duplicates have kidnapped Iris West and will only let her go if the Flash allows them to take Manuel, to which the Flash reluctantly agrees. Mob Rule had kidnapped Dr. Guerrero, the original doctor who gave Manuel his regenerative powers, and were forcing him to find out why they were dying. Even with Manuel as their hostage, the doctor could not find out why their lifetime was limited to just a few months. They killed Dr. Guerrero and replenished their ranks by cutting off Manuel's fingers and hands again.

Danny, now the Reverse Flash, kills a bunch of speedsters and steals their speed so he can go back in time to kill his dad and give himself a happy life, but he is stopped by the Flash. |
