Warning: The following feature contains SPOILERS for The Flash, season 6, episode 10, "Marathon."
The first episode of Arrowverse has more trouble than ever; luckily, Cisco Ramon has a binder full of villains charting it all. With several Earths having merged together post-Crisis, Earth-Prime is facing a sudden surge in its supervillain population and information on all of the bad guys is in short supply.
This would be bad enough, but as far as Cisco Ramon can tell, none of the heroic doppelgangers of Earth-1's heroes survived to be reborn on Earth-Prime to face off against their old arch-enemies. Worse yet, some of Earth-1's supervillains have reportedly come back from the dead with new or altered powers, and others have seemingly disappeared off the face of the Earth. Faced with a staggering amount of changes to the world he knows, and his powers no longer working (due to there no longer being a multiverse to breach across) Cisco has made it his mission to start gathering intelligence on every potential threat to Earth-Prime
While a binder full of self-designed supervillain trading cards might seem like a ridiculously low-tech way of tracking such important information, it is true to Cisco's geeky roots. It's also a sneaky tribute to DC Comics' Who's Who In The DC Universe; a comic book encyclopedia series which ran throughout the 1980s and into the 1990s, revealing the new history of the post-Crisis DC Comics universe. The following list is a rundown of every villain profiled in Cisco's Who's Who Binder and all the other villains and evil organizations he singled-out by name while discussing the new threats to Earth-Prime.
Abra Kadabra
A time-traveler from the 64th century of Earth-19, Citizen Abra violated his Earth's rules against breaching to other dimensions and many other laws besides. An unrepentant murderer and thief, Abra armed himself with advanced nanotechnology implants which allowed him to perform a variety of feats that appeared to be magic by the standards of 21st century Earth-1 science. He claimed to be one of The Flash's greatest enemies in the future, when Barry Allen faced him for the first time in the The Flash season 3, episode 18, "Abra Kadabra." The episode ended with Abra being taken back to Earth-19 to face execution for his crimes, but apparently the Crisis allowed him to cheat death... just like magic.
Amunet Black
Once a flight attendant named Leslie Jocoy, Amunet Black gained the power to magnetically manipulate certain iron alloys following the explosion of STAR Labs' particle accelerator. She adopted the alias Amunet Black and set herself up as a crime boss in Central City's underworld, specializing in metahuman trafficking and advanced technology. Ever the business woman, she agreed to help Team Flash in their battle against The Thinker, providing them with a weapon capable of disabling the satellites powering his Enlightenment. She disappeared from Central City after that, but the previews for The Flash, season 6, episode 11, "Love Is A Battlefield," indicate she's about to make a comeback.
Block
A weapons dealer for the East Street Skulls gang, Vanessa Jansen gained the power to create super-dense boxes of compacted air molecules after STAR Labs' particle accelerator exploded. Given the codename Block by Cisco Ramon, Jansen was wounded by the metahuman serial killer Cicada after Team Flash had subdued and arrested her in The Flash, season 5, episode 2, "Blocked." Despite Team Flash's best efforts, Block died before they could get her to the hospital in the Pre-Crisis timeline.
Bug-Eyed Bandit
A brilliant mechanic engineer employed by Mercury Labs, Brie Larvan created a mechanical bee capable of pollinating plants for agricultural purposes. Unfortunately, Larvan was of a more mercenary mindset than her bosses, and was fired after she began exploring unauthorized military applications for her work. As the Bug-Eyed Bandit, Larvan sought revenge on the co-workers who turned her in for misappropriating company resources and tried to steal an experimental bio-chip from Palmer Technologies. After facing defeat at the hands of both Team Flash and Team Arrow, Larvan ed up with the Young Rogues to rob McCulloch Technologies, but didn't prove to be any better as part of a criminal gang than she was as a solo act.
The Dominators
The Dominators are a telepathic alien race known for their love of conquest and experimentation on the inhabitants of other planets. The Dominators lay siege to Earth-1 during the Invasion! crossover event and demanded the execution of all metahumans, whom they saw as an obstacle to their expansion across the galaxy. The Dominators were also a major threat in the reality of Earth-38, where they helped facilitate the intergalactic slave trade and worked with the villain Roulette to abduct Earthlings who would not be missed.
Girder
A steel-factory worker with a history of violence and petty criminal activity, Tony Woodward was also Barry Allen's childhood bully. The particle accelerator explosion at STAR Labs just happened to occur as Woodward fell into a vat of molten steel while attacking the supervisor who informed him that he had been laid off. This left Woodward (who was later dubbed Girder by Cisco Ramon) with the power to transform any part of his body into solid steel. He was later killed by the villain Blackout, whom he was tricked into fighting by the Reverse Flash, in the Pre-Crisis reality.
Grodd
Grodd was once an ordinary gorilla and test subject at STAR Labs. His mind was enhanced by the particle accelerator explosion, giving him enhanced intelligence and incalculable psychic powers. Grodd went on to menace Central City on multiple occasions and ed forces with sorcerer Damian Darhk to fight the Legends of Tomorrow. Grodd's current whereabouts are unknown, but his psionic abilities were said to be growing stronger when he was last taken into ARGUS custody following a battle with King Shark.
The Hotness
Jaco Birch was an ordinary Central City citizen who just happened to be on the scene of a battle between pyrokinetic bank robber Eric Fyre and EMT Matthew Kim, who thought he had developed the power to take away the metahuman abilities of other people. In truth, Kim had the ability to transfer metahuman powers from one person to another, rewriting their DNA with a touch of his hand. Kim accidentally gave Fyre's power to generate flames at will to Jaco Birch, prompting Birch to go on a short-lived crime spree as The Hotness. He was quickly brought to justice by Iris West-Allen, who briefly assumed the duties of The Flash after Kim accidentally gave her Barry Allen's super-speed.
King Shark
Originally a marine biologist on Earth-2, Dr. Shay Lamden underwent a horrific transformation following the destruction of STAR Labs' particle accelerator, taking on the characteristics of a shark. Left in a savage state and dubbed King Shark, Dr. Lamden was a perfect minion for the villain Zoom and his war on Earth-1. He later acted as a test subject for Cisco Ramon's metagene cure during The Flash season 5, but ultimately sacrificed his humanity to save Central City from Gorilla Grodd.
Magenta
Frankie Bridge was an orphan who had been bounced from foster home to foster home. A lifetime of abuse caused Frankie to develop a dissociative personality disorder and a second persona called Magenta, which was given the power to magnetically manipulate metal by the villain Alchemy. Magenta attempted to kill Frankie's abusive foster father, but was thwarted by Team Flash. Frankie was later moved to a different foster home, with STAR Labs offering to help her if her Magenta personality ever emerged again.
