Maya Resik, mother of Sebastian Blood, has a name based on two characters from the comics: Anna Resik, mother of Brother Blood VIII, and May Bennett, mother of Brother Blood IX.
In Season 3, Ra's al Ghul chooses Ollie to be his successor, making this another TV Green Arrow with Batman elements. Ra's also wants Nyssa to be Ollie's bride, which kind of makes her Talia to his Bruce, although she's a lot more reluctant than Talia was. Also her status as a lesbian daughter of an immortal villain who wants her to give him an heir makes her similar to Scandal Savage. Talia did eventually appear, but in a more antagonistic role, akin to Nyssa's original role, as Prometheus' mentor in order to avenge her father, and was revealed to have trained Oliver in Russia in the past, whereas Scandal, renamed Cassandra, also showed up on Legends of Tomorrow.
Ray Palmer is still a scientist who eventually gains the power shrink, but he's also a cheerful billionaire who runs his own company, like Ted Kord. According to Word of God, this is because Ray originally was going to be Ted when Arrow Season 3 was being planned.
Deathstroke's shared experiences on the island with Oliver, his burn injuries, and his vendetta against the Green Arrownote Though he did actually have a slight grudge on Green Arrow in the original comics following Identity Crisis (2004), even attempting to crash his wedding with Black Canary are all taken from the New 52 version of Tommy Merlyn (though after Slade's Heel–Face Turn in the season 5 finale, evil doppelgangers of Tommy based on his New 52 self (neither of whom have the burns and presumably the island experience) appeared during Crisis on Earth-X and Arrow season 8, the former as Earth-X's Prometheus rather than Adrian Chase (this one didn't have a vendetta with his world's Oliver, them both members of the New Reichsman), the latter as Earth-2's Dark Archer rather than his father Malcolm (it was revealed Oliver had died on Earth-2 instead of his father Robert, who was implied to have become Green Arrow's initial vigilante identity The Hood instead, and was ultimately replaced in the mantle by Adrian Chase, whom was a heroic doppelganger of the villainous Prometheus identity he had on Earth-1, by the time Oliver went to Earth-2 himself)).
The series combines Isabel Rochev/The Queen with Rose Wilson/Ravager III, to create a version of Rochev who becomes Slade Wilson's apprentice in a version of his costume (Rose) because she wants revenge on the Queen family following a relationship with Robert Queen (Rochev).
Felicity Smoak is eventually revealed to be the daughter of the Calculator, much like Wendy Harris from the comics.
In season 4, Damien Darhk's role as leader of H.I.V.E. comes from his comics' namesake (as, possibly, does his immortality, although with comicbook Damien that was only hinted at). His role as a former senior member of the League of Assassins seems to be based on the similarly named Ebenezer Darrk.
In season 5, Prometheus is revealed to be the alter ego of Adrian Chase, a separate character in the comics. Vigilante still appeared, but Black Canary II's believed deceased boyfriend and police partner Vincent Sobel turned out to be him, having survived death by becoming a metahuman who survives fatal injuries.
Artemis is a young archer hero like in Young Justice (2010), but her real name of Evelyn Crawford Sharp (as well as her status as a Mole within the team who is secretly working for a villain) comes from Ev Crawford, a.k.a. Starling, a character from the New 52Birds of Prey relaunch.
In season 6, Slade's son Joe became a ruthless killer because he wanted to be like Slade, much like the comicbook Grant Wilson/Ravager II. He's also the leader of a terrorist organisation called the Jackals, which is a reference to William Walsh/Ravager I/The Jackal. And then it turns out he has a brother named Grant who their mother kept away from Slade to avoid him ending up the same way. It remains to be seen how much he's like the comics' Joey Wilson/Jericho, though he does prove to be an effective substitute once Slade's appearances in Justice League (2017) and Titans (2018) made him Screwed by the Lawyers for the Arrowverse, and Joe winds up a Deathstroke equivalent for a revamped Suicide Squad in Arrow season 7.note Grant Wilson himself had actually already appeared in the Arrowverse by then, in an alternate future to Star City witnessed during Legends of Tomorrow, here, he took the mantle of his father and lead a Deathstroke gang in control of the city. This future was later replaced in Arrow season 7 with a separate future where JJ Diggle lead the gang, though Grant eventually returned in season 8 as a former leader of said gang.
Mary Hamilton, based on the comic character of Mary Elizabeth "Bette" Kane / Flamebird, turns into the second Poison Ivy due to a plant from the first Poison Ivy.
The Monitor combines his original character with that of Krona from Oa in the original comic book series, who ended up creating the Multiverse by performing the forbidden act of using science to peer into the beginning of time and space.
The villain Gravedigger uses the general backstory (and cross-shaped scar) of Ulysses Hazard, the first (heroic) Gravedigger; the name and power of Tyson Sykes, the Checkmate operative Gravedigger who gave himself telepathic abilities by injection; and combined with elements of Marvel Character Isaiah Bradley (enhanced physical abilities in an experiment in which most unwillingly subjects died to duplicate Captain America's Super-Soldier Serum).
The villain is Dr. John Deegan, better known as Dr. Destiny in the comics, but his wish to make the world the way he wants, his pretentiousness, his psychopathic childishness, and using the Book of Destiny to turn himself into an Evil Twin of Superman makes him more in line with Superboy-Prime.
The Reverse Flash seems to largely be based off the original Silver Age version, but he also has the red eyes of Hunter Zolomon and gains his wheelchair gimmick after impersonating Harrison Wells.
The titular hero himself is Barry Allen; however, with his Adorkable ways and younger age than most incarnations, Barry resembles Wally West often at times. Then in "Crazy For You", Linda Park, the most famous Wally West Love Interest, is introduced for Barry's interest.
There is no single comic counterpart for Eddie Thawne. He's a present-day ancestor of Eobard Thawne like Malcolm / Cobalt Blue, and he's given his descendant's romantic feelings for Iris West. He's visually similar to Barry's comic self, and he's also a Friend on the Force for the Flash like pre-Face–Heel Turn Hunter Zolomon.
The female Doctor Light appears in Season 2, and while she's still Asian, she's the Earth-2 version of Linda Park instead of the mainline universe's Kimiyo Hoshi. She's also a villain, like the white, male Dr. Light, though with far different motives (wanting to Kill and Replace her Earth-1 self, versus the rapist nature of Arthur Light). After Crisis on Infinite Earths (2019), the actual Kimiyo Hoshi appears in season 6 as a member of Black Hole.
Hawkgirl is named Kendra Saunders, like the version of the character introduced in the late 90s, but her backstory comes from the Golden Age Hawkgirl, Shiera Sanders Hall, being a reincarnation of Chay-Ara, rather than a walk-in spirit, especially due to being paired off with Carter Hall, the Golden Age Hawkman.
Wally West is Iris' younger brother rather than her nephew, making him the show's equivalent of the New 52's Daniel West.
Earth-2 Harrison Wells is the father of Jesse Quick instead of Johnny Quick. He also created a drug called "Velocity 6" - in the comics Velocity 9 was created by Vandal Savage.
Earth-2's Hunter Zolomon/Zoom is perhaps the most dramatic example for this on the show. He has the name and childhood trauma of the second Reverse Flash, but his dark suit is similar to that of the Black Flash, the Psychopomp of speedsters that he was forcibly drafted into becoming at the end of Season 2. He takes his father's place as a serial killer (though his father is still a murderer, just of his mother, making him a Foil to Barry, who too lost his mother, but his father was innocent, leading to a scene where Zoom murders Barry's father Henry in the same manner as Barry's mother's death), and the blue lightning he produces while running is similar to that of an evil Barry Allen in an alternate timeline. His use of a drug to maintain his speed is reminiscent of the second Crime Syndicate Johnny Quick and his "speed juice". Said drug being Velocity 9 may also be taken from the sociopathic teenage speedster Inertia. Finally, he takes the place of Edward Clariss/The Rival by serving as Jay Garrick's archenemy, wearing a dark copy of his suit, though it was later revealed that Jay Garrick had been captured all along and would be met after the heroes defeated Zoom, the Jay they actually met at first was a Fake Ultimate Hero time remnant conceived by Zoom so he could have an enemy to inspire hope that he would crush later. The Rival later appears in season 3 as a separate character with a different costume than the one he usually wears.
The Big Bad of Season 3, Savitar, claims to be a "god", leader of a cult and imprisonment in the Speed Force are all elements taken from the comic book villain of the same name. However, he also poses as Julian Albert's alter-ego Doctor Alchemy (taking the place of Julian's split-personality "Alvin"), and, in the future, is apparently the one to kill Iris West (a crime that should have been committed by Professor Zoom/Reverse-Flash).note The way in which the murder is averted, however is different, Iris in the comics survived because her mind escaped to the future, where Barry could reunite with her later. Here, H.R. Wells switches places with Iris and disguises as her to die instead. And finally, Savitar's true identity as Barry's deranged future self makes him a counterpart to the Future Flash, albeit instead as a time remnant of said future self, the actual future Barry encountered later is a morose character who isn't evil.
The Arrowverse version of Hazard emits a special probability field that constantly brings her good luck while causing everyone near her to experience bad luck. That's not how Hazard's powers work in the comics (where she has psionic abilities and a special pair of dice, which, when used in tandem, allow her to manipulate probability), and instead calls to mind the abilities of the Justice League villain Amos Fortune.
The show's version of Ralph Dibny a.k.a. Elongated Man has a personality and history that makes him more similar to Plastic Man.
Nora West-Allen is Barry's Kid from the Future like the comics' Dawn Allen (one half of the Tornado Twins) and Nora Allen (the heroine Cruise), but her superhero codename is XS, the name used by Barry's granddaughter in the comics. And in the comics, the role of "Barry's future descendant who comes back to meet him but doesn't always think things through" is taken by his grandson (XS's cousin) Impulse.
Bart Allen / Impulse would eventually make his appearance as well, going back to the past along with Nora, but he is now Barry's son, much like his own father Don Allen, Barry's otherKid from the Future and the other Tornado Twin.
Jocelyn "Joss" Jackam, the young adult daughter of Weather Wizard who goes by Weather Witch, is a composite of the comic Weather Witch, who had no connection to Mardon except getting hold of his weather control wand, and comicbook Weather Wizard's infant son Josh Jackam.
The villain Rupture is the Earth-2 counterpart to Cisco's brother Dante. In the comics, Rupture is Cisco's other brother Armando, who was Adapted Out of the series.
In the comics, Jay Garrick is entirely unconnected to Henry Allen. In the show, they're alternate universe counterparts of each other. This is continued in season 7 when their respective wives, Nora Allen and Joan Garrick, also are counterparts of each other.
In Dark Nights: Metal, the Red Death was an alternate universe version of Bruce Wayne who had stolen the powers of his world's Flash. Red Death shows up in the final season of the series, where she is instead an alternate universe version of Ryan Wilder.
Sara Lance is a complicated example. She was originally a Decomposite Character of Black Canary (she replaced her mother, albeit under the name The Canary, while her mother was never a vigilante), but was given the code name of White Canary, a villain from the comics, to differentiate her from her sister Laurel, who had taken up the Black Canary identity during the period where Sara was dead.
Jefferson "Jax" Jackson is a cocky former high school football star like the comic version of Ronnie Raymond, the original Firestorm, but is visually very similar to Jason Rusch, the second Firestorm (who appeared in The Flash (2014) as a scientist involved with creating the F.I.R.E.S.T.O.R.M. Matrix). And his name comes from Ronnie's best friend in the original comics.
The Time Masters are a Time Police organisation similar to the comics' Linear Men, whereas the comicbook Time Masters were just Rip Hunter's four person exploration team.
Chronos is Mick Rory/Heat Wave, after getting picked up by the Time Masters.
Nate Heywood/Steel is a combination of the comics' Nathan Heywood/Citizen Steel and Hank Heywood III/Steel. Both were grandsons of Hank Heywood Sr./Commander Steel, but Nate is the son of Hank Heywood Jr., like Hank III but unlike comic book Nathan. He has Hank III's codename ("Steel" with no title) but Nathan's powers (steel skin rather than being a cyborg).
In the Trapped in TV Land episode, the Friends parody has Nate as Joey (dumb actor) and Behrad as Ross (Zari's brother), but they both have Chandler's mannerisms. The villainous aliens in the Star Trek parody are called "Gromulans", but look like Klingons.
The Ray of the series is the Post-Crisis Ray, Ray Terrill, with a costume based on one Ray used in the comics, but he also has a lot of elements of various incarnations of Langford "Happy" Terrill, the original Golden Age Ray and his father in the comics. Happy was a reporter, his post-Crisis origin involved a government conspiracy studying the uses of light, and his Earth-10 counterpart is gay.
The four-way crossover Crisis On Earth X has the Dark Flash, who has a costume and role similar to those of the Nazi Flash from the comicbook Earth-10. His true identity is revealed to be Earth-1's Eobard Thawne, still not erased from existence for some reason. An actual Dark Flash, the Earth-X Barry, had appeared in Freedom Fighters: The Ray, but was killed off in that show.
Hank Henshaw, who in the comics is the original human identity of Cyborg Superman, turns out to be an alias used by Martian Manhunter. A downplayed case, since Hank Henshaw did exist in the series until Martian Manhunter started impersonating him, and is later revealed to still be alive. As the head of the DEO, J'onn and, by extension due to his Race Lift, Henshaw were also combined with the canonical head of the DEO, Mister Bones, as Henshaw was Race Lifted into an African-American (though some shows, such as Young Justice (2010) and Smallville, had previously shown the John Jones identity to be African-American as well), as while all bodily tissues but his bones are invisible, Bones is noted to be a black man. His initial distrust of other aliens and contentious relationship with Superman come from Batman. Also, like his own DC Animated Universe counterpart, this version of J'onn has two daughters instead of just one.
The show also combines the two different versions of Silver Banshee giving us a character with the same name as the heroic New 52 Siobhan Smythe but a personality much more like the evil Siobhan McDougal from the older comics.
In Season 2, James Olsen becomes the Guardian, a separate vigilante character in the comics, despite Jim Harper, the first Guardian, also appearing. James' Race Lift into an African-American is likely a way to make him the show's version of Malcolm "Mal" Duncan, the second Guardian.
Myxzptlk is based on the Superman villain of the same name. His obsession with the show's protagonist makes him similar to Bat-Mite.
In the series Rama Khan from the Justice League of America storyline "Golden Perfect" is Leviathan. In the comics, Leviathan is Mark Shaw, the original Manhunter, although since these reveals happened in the same week, the series didn't exactly have the option of following the comics more closelynote The original Leviathan group notably was led by Talia al Ghul in the pages of Batman Incorporated.. Later episodes suggest the whole Leviathan organisation has been combined with the League of Ancients, a group Khan and (current Leviathan leader) Gamemnae were a member of in "The Obsidian Age".
Near the end of Season 1, Morgan Edge, reinterpreted as Superman's evilstepbrother Tal-Rho, becomes the Eradicator after merging with its technology.
Bizarro appears in Season 2, but his introduction, which involves being clad in some sort of containment suit and violently punching his way to the surface after having been trapped underground, is taken directly from Doomsday's debut in The Death of Superman. The season 3 finale then sees Bizarro be given Doomsday's backstory of repeatedly being killed over and over to become stronger, eventually transforming into Doomsday as a result.
This series' interpretation of Lex Luthor, by repeatedly killing Bizarro over and over to turn him into Doomsday, fills a similar role to Bertron, who created Doomsday in the comics.
