Lian Yu Survivors
A group of people who all somehow arrived on Lian Yu, an island in the North China Sea, at relatively the same time. They banded together after being targeted for death by a group of mercenaries that were also on the island for an undisclosed mission. After the mercenaries were defeated, they continued to stick together in order to increase their chances of survival, becoming a makeshift family.
- Adaptational Badass: Getting trained by the League of Assassins will do that to you. Even Oliver, no slouch in his canon incarnation, is far more competent here.
- Adaptational Personality Change: Landing on Lian Yu at young ages has drastically changed the personalities of all three leads, and they are markedly different from their canon counterparts.
- Oliver is far less of a jerk than he is in canon (in fact he's a borderline Nice Guy), and, most noticeably, not a playboy; this is largely because he washed up on Lian Yu at a younger age, before he really took on the 'party boy' persona. In fact, the trauma of everything he went through during those ten years had stunted his emotional growth to the point that he can't differentiate between romantic and platonic feelings, be they his or someone else's.
- By contrast, Barry is far more abrasive and confident (though still, ultimately, a Nice Guy). He's also far more accepting of tragedy and the overall 'darker' side of life, thanks to the events of Lian Yu and his time in the League.
- Kara is the one most similar to her canon counterpart, but even she has changed; she's noticeably less silly and more maternal, thanks to being Kal-El's primary caretaker and the balancing force between Oliver and Barry. She is also far more bloodthirsty than canon!Kara when in battle.
- Arbitrarily Large Bank Account: They all have one thanks to their work with the League. It doesn't have much impact on the plot beyond funding their vigilante activities; Oliver was already rich to begin with, and Barry already had a home and all its necessities with the Wests. Only Kara used hers (disguising it as money inherited from her non-existent parents), and that was to buy a nice condo for her and Kal, and pay for his Balliol tuition fees. Subverted in that they finally decide to invest the money for new streams of income: Oliver and Kara plan to open an affordable shopping center to help rehabilitate the Glades, while Barry plans to reopen S.T.A.R. Labs.
- Base-Breaking Character: In-universe, the Hood and the Streak are extremely polarizing since they're slitting throats and using criminal as pincushions to clean their towns. The Girl in Blue is spared from this since she's mainly seen saving people.
- Big Eater: Courtesy of an enhanced metabolism, Kara, Barry and Kal are able to down unholy amounts of food on their own. Oliver's horrified resignation while he looks at the scene is almost a Running Gag.
- Dark and Troubled Past: Very much so.
- Family of Choice: They still refer to each other family even after being rescued from Lian Yu and returning to modern civilization. This aspect of their bond is so strong that when someone suggests the possibility of a romantic relationship between any of them (barring Slade and Shado), it visibly sickens them.
- Five-Man Band:
- Lian Yu
- Post-Lian Yu
- Freudian Trio: Oliver, Barry, and Kara. Barry, despite his personality, is the Superego, Kara is the Id, and Oliver the Ego.
- Pop-Cultural Osmosis Failure: They are all completely lost when it comes to popular culture for the last ten years. Kara and Kal were born on another planet entirely, so nearly every reference goes over their heads. While Oliver and Barry have some passing familiarity with works prior to their disappearance such as Harry Potter and Marvel Comics (with Barry in particular taking delight in the advent of the Marvel Cinematic Universe), franchises like High School Musical and Twilight are completely foreign to them.
- Pragmatic Hero: While they have fundamentally good intentions and largely avoid killing unless absolutely necessary, they also aren't afraid to blackmail or torture to get what they want.
- Properly Paranoid: They have a number of safeguards for specific situations that seem Crazy-Prepared at first glance but in the end turn out to be this. This is nominally due to previous experience from their time in the League of Assassins.
- Submissive Badass: For all their power and skill, they are ultimately under the heel of two organizations: The League of Assassins and A.R.G.U.S.
- The League not only trained them, but is also privy to almost all of their secrets, including their identities, pasts, and weaknesses. On top of that, their influence is far-reaching, spanning all across the globe. While they are content to let the three leads act on their own accord as long as they hold up League principles, they have made it clear that they will directly interfere if they act against League laws. Notably, Barry and Kara refused to let an emotionally-compromised Oliver go after Malcolm until after they had Ra's al Ghul's approval. Considering that they have superpowers, and two of the most powerful beings on the planet in general, that says a lot about how much they respect and fear Ra's.
- A.R.G.U.S., like the League, knows a lot of their secrets and weaknesses. However, the real danger in them is that they have the backing of the entire United States Government. Amanda essentially got them to work for her by threatening to put Slade at the top of the Most Wanted list.
- Stealth Hi/Bye: All of them enjoy pulling this to one extent or another, either for tactical advantage or to tease their friends.
- True Companions: After ten years of hell together, suffering torture, backbreaking training, and baby raising, their bond is unbreakable.
- Two Guys and a Girl: Oliver, Barry, and Kara, given that they're the only teens.
Oliver Queen / Al Sah-him / "The Hood" / Green Arrow
The oldest of the younger generation and one of the three main characters. Born in Starling City as the firstborn son of the wealthy Queen family, Oliver was enjoying a vacation to China when the yacht he was sailing on capsized during a Category 2 Storm in the North China Sea. Landing on Lian Yu, he finds his destiny — along with three others whose fates are intertwined with his.
- Adaptational Nice Guy: Since he hadn't adopted his playboy personality yet when he first washed up on Lian Yu, this Oliver doesn't feel the need to put up an act and push people away.
- Big Brother Instinct: For the rest of the younger generation, which is partially why he became The Leader when Shado died and they were separated from Slade.
- Determinator: It's noted that Oliver always pushed himself to be the very best during his time in the League, and Kara describes him as their rock when the group were on the island.
- The Gift: It's noted that Oliver is one of the most talented recruits in the history of the League of Assassins. It only took him a few years to reach the same level as Ra's al Ghul, who has centuries of experience over him. What makes it even more impressive is that he's managed as a young adult.
- Happily Adopted: Robert immediately acknowledged a newborn Oliver as his son in spite of knowing the baby had been conceived by his wife's extramarital affair.
- Heroic Bastard: He was conceived when Moira and Malcolm cheated on their respective spouses with each other.
- The Leader: While ostensibly the three main characters are equals, Barry and Kara usually default to Oliver's leadership.
- Living Emotional Crutch: Oliver is the one who kept the group going even when they were at the absolute lowest. According to Kara, without him, there's no way they would've lasted those ten years, or that they would even want to.
- The Load: The League of Assassins thought he would be this compared to Barry and Kara. He proved them wrong.
- Locked Out of the Loop: No idea whatsoever of his Heroic Bastard status, and the Queens intend to keep it this way.
- Oblivious Adoption: He genuinely believes Robert Queen is his birth father and the Queens never gave him a reason to think otherwise.
- Oblivious to Love: Completely oblivious to Laurel's not-so-subtle crush on him.
- Straight Man: To Barry's Wise Guy.
- What Is This Thing You Call "Love"?: Downplayed. While Oliver understands love on an intellectual level and is by no means aromantic or even asexual, he has a hard time differentiating between familial/platonic love and romantic love. For example, it's only after Tommy accuses him of "putting the moves" on Laurel does he realize that he might have feelings for her, and it's only by comparing how he feels about Laurel to how he feels about Nyssa does he realize he also might have feelings for Nyssa as well.
- World's Best Warrior: According to the narrative, Oliver was the best combatant in the League next Ra's al Ghul himself, and there were rumors that he had actually managed to surpass Ra's.
Barry Allen / Al Sa'iqa / "The Streak" / The Flash
The middle child of the younger generation. Born in Central City as the only child of a middle-class family, Barry found his life irreversibly changed one night when a man in a yellow suit appeared in a storm of lightning and murdered his mother. His father was arrested and convicted for the crime, despite Barry's claims for his innocence, and Barry was forced to live in the home of his childhood best friend, Iris West. After three years of constant ridicule, a late-night argument with his foster father pushes him over the edge, and he traveled abroad to study in China, forever altering his fate.
- Adaptational Intelligence: While canon!Barry was far from stupid (though he did have a tendency to grab the Idiot Ball), this Barry is a confirmed genius whose intellect is easily on the same level as Eobard Thawne's.
- Beware the Silly Ones: Barry enjoys playing The Gadfly, is an Insufferable Genius and a total nerd...who's also an Empowered Badass Normal skilled in hand-to-hand combat, knife-fighting, and his speed, who can and will cut the throats of people he believes are too deadly to keep alive. Oh, and he's an expert hacker.
- Childhood Friend Romance: With Iris, though Barry is ignoring his feelings for now while Iris is just oblivious to the situation.
- Double Reverse Quadruple Agent: His Arc III storyline has him going undercover and joining Snart's crew for a major heist, while at the same time reporting his activities to Ralph and Iris. Unbeknownst to both sides, however, is that Barry is the Flash, with his real allegiance being to the Justice League and their allied organizations, including A.R.G.U.S. and the League of Assassins.
- Empowered Badass Normal: Goes from expert, League-trained combatant to an expert, League-trained combatant who is also a speedster. This actually becomes a plot point during his first fight with Thawne — Barry doesn't fight like a traditional speedster, having been an assassin with years of training before he gained his powers. He relies on those abilities first and uses his speed to augment them when necessary.
- The Gadfly:
- Hot Scientist: Barry is very attractive.
- Hollywood Nerd: Lampshaded by Eddie when they finally meet in person.
- I Want My Beloved to Be Happy: His current stance in regards to Iris, which is why he encourages her relationship with Eddie.
- Insecure Love Interest: One of the reasons why Barry refuses to pursue Iris is because some part of him honestly believes he isn't good enough for her.
- Insufferable Genius: Another facet of Barry's personality the causes friction is that he has absolutely no issue showing off his intellect, especially his deductive ability.Cisco: Has anyone told you how annoying it is when you do that?
Barry: Yes. Usually I just ignore them.
Caitlin: That explains a lot.
- Knife Nut: Barry's Weapon of Choice.
- Living Emotional Crutch:
- Oliver briefly thought of throwing the towel when stuck on Lian Yu, but instead soldiered on for Barry's sake since the other boy was more vulnerable.
- His need to prove his father's innocence gave Barry the strength to survive and grow beyond his limits. It also was reciprocal, since hearing his son was likely deceased drove Henry over the Despair Event Horizon and made him attempt suicide.
- Loves Secrecy: It was necessary and inconvenient, but regardless, Barry really enjoyed stringing along Caitlin and Cisco (and, to a lesser extent, Thawne) for the first two arcs.
- Mad Scientist: Implied to have been one when he was still a member of the League.
- Omnidisciplinary Scientist: Barry was the League of Assassins' most brilliant mind, and they stretched him to the absolute limit when it came to piling knowledge in his head. Becoming a speedster just made it easier to compartmentalize all that knowledge and use it.
- Teen Genius: He correctly theorized the source of Kara's powers when he was just fifteen.
- Troll: Again, much to the chagrin of everyone who knows him.
- We All Die Someday: A crucial difference between this Barry and canon!Barry is that this Barry, after having lost other loved ones and joining an organization that explicitly teaches its members how to kill, has long since accepted death as another facet of life. This is ultimately the reason why he refuses Eobard's offer to prevent his mother's death.
Kara Zor-El | Kara Danvers / Saraab / "The Girl in Blue" / Supergirl
The only female of the younger generation. Born on the planet Krypton, Kara's path was decided for her when her family learned their planet was doomed. She and her younger cousin, Kal-El, were forced into a single ship and shot out into the sky as their home planet exploded around them. Eventually, their journey ended, and they found themselves in a new world, with new lives to live.
- Big Brother Mentor: She plays a gender-swapped version of this role to Kal-El.
- Boxing Lessons for Superman: Almost literally, as the League doesn't want her relying just on her powers. She ends up thankful when she has to go up against her aunt and other Kryptonians and beings of similar abilities.
- Celibate Heroine: Kara has no interest in romance, at least currently. She's more concerned with raising Kal-El to the best of her abilities. A Justified Trope since she spent her adolescence raising a baby brother and learning from the League.
- Cool Big Sis: To Kal-El.
- Cool Sword: Her Weapon of Choice, with the blade made out of kryptonite for good measure.
- Drama-Preserving Handicap: Why Kara developed her powers gradually instead of getting all of them at once in the prologue.
- The Dreaded: Out of all the vigilantes, Kara is by far the most feared due to her Combo Platter Powers.
- From Nobody to Nightmare: Starling City's perception of her — she was only an orphan castaway who had the good luck to end up on the same island as the Queen heir, and their friendship allows her to enter the inner circle of Starling's elite.
- The Heart: While Oliver and Barry are by no means amoral and still have empathy, Kara is the one most connected to her emotions and does the same for them. It's also deconstructed, as that means Kara is the one who is the most conflicted over the moral ambiguity over the trio's vigilante activities.
- I Did What I Had to Do: Tells this to Astra, when the latter asks what happened to her.
- I Owe You My Life: The source of her loyalty to Oliver and Barry; the two had just been tortured by Fyers and Wintergreen and had no reason to help out a hysteric alien girl and a crying baby that had just arrived on the planet. But they still made the effort to calm her down, learn her name, comfort her, and ultimately save her from Fyers and his men.
- Only Sane Man: She's the one that usually has to break up Oliver and Barry's arguments.
- Parental Substitute: She's the closest Kal-El has to a mother, which is why Kal goes to live with her when they finally move out of the Queen Mansion.
- Promoted to Parent: She, along with the others, was responsible for raising her baby cousin.
- The Reliable One: Thanks to the versatility of her powers, Kara is usually the one that deals with enemies that Oliver or Barry can't immediately defeat. It also applies to normal life; thanks to her lack of a job and a social life beyond raising Kal-El, she's open to helping her friends whenever necessary.
- Social Climber: A very accidental one — making friends with Oliver on Lian Yu means the Queens pratically consider her a second daughter, and Starling's elite tailors their treatment of her accordingly.
- Token Good Teammate: Her standing in the public opinion is much more positive than Barry's and Oliver's. She focuses on saving people and preventing disasters instead of killing criminals, so she's not a Base-Breaking Character like the boys.
- World's Best Warrior: Due to a combination of her Combo Platter Powers and League training, she's almost unbeatable. It takes fellow Kryptonian and expert warrior Astra to even give her serious trouble.
- Worthy Opponent: Sees her aunt as this after Astra gives the best fight she's had since first gaining her powers.
Kal-El | Clark Calvin Kent
The youngest of the group, Kal-El was just a baby when his world was destroyed and he was put under the care of his twelve-year old cousin. As a baby raised in hell, Kal-El's early childhood was very much unconventional, but with no less love than the one he would have received on Krypton. Despite all that, the effects of a very turbulent childhood still show, and will probably continue to affect him for the rest of his life.
- Alliterative Name: Clark Calvin Kent.
- The Baby of the Bunch: Quite literally. He was a baby when he and Kara landed on Lian Yu.
- Big Brother Worship: A gender-swapped version. Barry quite accurately calls him Supergirl's biggest fan.
- Cheerful Child: Generally pretty upbeat and cheerful.
- Future Badass: In an alternate timeline, he was Superman, the greatest superhero in the world. It's implied that he will still become Superman someday in the future.
- Living MacGuffin: Some shades of this.
- Astra muses about using him to control Kara. It didn't go this far, fortunately.
- Waller eyes him as a potential asset due to his burgeoning Combo Platter Powers. Kara immediately vetoes the option.
- Out of Focus: Due to his age, he doesn't take part in much of the action.
- Shrinking Violet: Around new people, though he slowly grows out of it the more he get familiar with them.
- Sugar-and-Ice Personality: He tends to hide behind Kara when around people he doesn't trust or knows very well, courtesy of the League beating emotional control in him since his early childhood. When he's amongst family and friends, he's a very normal, happy kid.
- Troubling Unchildlike Behavior: While Kal-El is a good kid, it's clear that his less-than-ideal childhood has had some odd effects on him. He was handling a knife when Kara came to give him documents about their human identities, and he knows how to spot a listening bug when he sees one.
Slade Wilson / Deathstroke "The Terminator"
An ASIS agent that was sent to Lian Yu alongside his partner Billy Wintergreen to rescue a rogue Chinese operative, Yao Fei Gulong. Upon arrival, they were captured by a group of mercenaries also hunting down Yao Fei; Wintergreen sided with the mercenaries, betraying Slade. Slade found himself on his own, his sense of trust thoroughly broken — until a couple of kids and a baby showed up at his hideout.
- Empowered Badass Normal: Didn't have, or need, superpowers at the beginning of the story. The Mirakuru made him even more dangerous, and after A.R.G.U.S. derived the cure for the side effects, he also manages to keep his head while using it.
- Everyone Has Standards: Very much rattled when Kara decides to bring Kal on a dangerous mission, he insists that the kid will stay away from possible fights.
- Hero of Another Story: Went through Oliver's canon journey, except that he didn't immediately go home because Amanda Waller saw him as too valuable and press-ganged him into joining Task Force X.
- Official Couple: With Shado in the prologue. It doesn't last, unfortunately.
- Papa Wolf: You do not touch Slade's kids.
- Parental Substitute: To the younger generation of the Lian Yu survivors.
The daughter of former Chinese general Yao Fei Gulong, Shado traveled to Lian Yu in search of her father, only to be captured by mercenaries and held hostage. Shado eventually escaped thanks to an ASIS operative and a group of kids, and joined up with them in return.
- Death by Origin Story: She dies in the prologue, and her death is what eventually leads to the leads joining the League of Assassins.
- In Spite of a Nail: Despite all the changes to the timeline, Shado still dies from a gunshot wound.
- The Lost Lenore: To Slade.
- Official Couple: With Slade.
- Team Mom: Strongly implied to be this for the young castaways, to the point that Kal-El referred to Shado as 'Mama' before her death.
- The Medic: She was a med student and functioned as this for the group, even passing the knowledge down to Barry before her death.
Family & Friends
The Queen Family
The Patriarch of the Queen family and father of Oliver Queen, Robert has been stuck in his own personal hell after the presumed death of his son. Blackmailed by his former best friend Malcolm Merlyn to aid in a most heinous plot, Robert has done everything in his power to protect his remaining family, and finds things only looking up when his son returns from the dead.
- Good Parents: Nothing but loving and supportive towards his children everytime they're onscreen together. He doesn't even care about one of them not being biologically related to him.
- Happily Married: With Moira.
- Nice Guy: Forgave Moira for cheating on him with his best friend and deeply loves Oliver in spite of not being his blood father.
- Papa Wolf: Robert is fiercely protective of his children, regardless of whether or not they're of his blood.
- Secret Secret-Keeper: When his wife presented the infant Oliver to him, Robert immediately realized the baby wasn't his son, yet accepted him as such. When the truth comes to light, he reassures Moira her having an affair never mattered to him, and he loves both of them.
- Spared by the Adaptation: Thanks to a timely business issue, Robert never got on the Queen's Gambit, which ultimately saved his life.
- "The Reason You Suck" Speech: Delivers a truly savage one to Malcolm after Tommy was shot, in which he bluntly tells his former friend he lost any right to love Oliver as a son after sinking the Gambit.
- We Used to Be Friends:
- With Malcolm. While they still maintain their friendship in public, in private Robert has made it clear that whatever was left of that friendship died with Oliver.
- With Frank Chen, after learning that it was Frank that planted the bomb on the Gambit and stranded Oliver on Lian Yu.
- Wicked Stepfather: Averted as hell! He had a ready-made Freudian Excuse to despise Oliver for being his wife's adulterous offspring, yet he embraced the kid as his own and mourned him for ten years before showing nothing but happiness when he came back alive and well.
- Your Cheating Heart: Had a weakness for women. After Oliver's death, however, he's made an effort to curb this fault of his and has mostly succeeded.
The matriarch of the Queen family and mother of Oliver Queen, Moira has been stuck in the same hell as Robert, blackmailed into joining Tempest alongside him and aiding Malcolm Merlyn with his plot to destroy the Glades. Her life now a moral crisis, Moira finds hope when her son is found alive, and finds herself forming an odd maternal bond with one of the friends that came with him.
- Composite Character: According to the author's notes, she's one with Cat Grant, fulfilling the "mother figure" role that Cat did to Kara in the series.
- Happily Married: With Robert.
- Mama Bear: Is not afraid to threaten Malcolm to protect Oliver from his influence, and when she found out it was Frank who planted the bomb on the yacht, she brutally slapped him and called him out for his actions.
- Parental Substitute: To Kara, fulfilling the maternal role model she'd been lacking since the deaths of her biological mother and Shado. Which is partly why Astra resents her so much.
- Rags to Riches: Worked her way up from the Glades to Starling City's wealthy elite.
- Shipper on Deck:
- For Oliver/Laurel, which is a strong possibility.
- For Carter/Kara, which will never be happening, with Kara's disinterest in romance being only one reason.
- Your Cheating Heart: She slept with Malcolm as a way to punish Robert for his own philandering ways. It resulted in Oliver's conception and birth.
The daughter of the Queen family and sister of Oliver Queen, Thea lost her brother at a young age, and sheltered thanks to her parents' over-protectiveness. With her brother's return, however, her parents begin to lighten up, and her life no longer so stifling.
- Big Brother Worship: Downplayed. While Thea couldn't help but resent her parents for being so overprotective, she never held it against Oliver.
- Demoted to Extra: Thea isn't a major character, mainly because she's mostly sheltered instead of spoiled and wild. She doesn't need a lot of Character Development.
- Related in the Adaptation: Since her and Oliver were swapped parentage-wise, she's Robert's legitimate child.
Dinah Laurel Lance / Black Canary
The eldest child of the Lance family, and childhood friend of Oliver Queen. Laurel was devastated over the death of her close friend, and its effects still linger a decade later, when Oliver returns. A lawyer for CNRI and absolutely devoted to the rule of law and the pursuit of justice, Laurel finds herself off-balance by the return of not only her friend, but by the appearance of a mysterious hooded vigilante that goes outside the law to achieve the results she seeks.
- Adaptational Badass: Becomes Black Canary far earlier than she did in canon.
- Amoral Attorney: Averted; she's definitely one of the good guys.
- Badass Normal: Not to the same extent as Oliver (though that's not saying much), but she fights crime with just Good Old Fisticuffs.
- Everyone Can See It: It's not a secret she has feelings for Oliver.
- Guilty Pleasures: High School Musical was this for her in college. She watched all three movies, much to Sara's disbelief and later amusement.
- I Don't Want to Ruin Our Friendship: Why she refused to go on a date with Tommy; she didn't return his feelings, and felt it wouldn't be fair to start a relationship with him when it was his best friend she really wanted.
- Interclass Friendship: With Oliver and Tommy. This led to the Lances in general becoming members of Starling's Elite, despite not having the networth normally found in this class.
- Unresolved Sexual Tension: With Oliver.
- Two Guys and a Girl: With Oliver and Tommy.
Detective Quentin Lance
The Patriarch of the Lance family, and father of Laurel Lance and Sara Lance, Quentin is a detective for the SCPD. Similarly justice-driven like his daughter, Quentin is also off-put by the appearance of the hooded vigilante, and finds his worldview gradually changing.
- Birds of a Feather: Befriends Joe West, another honest and hardworking cop, at the Thanksgiving party.
- Happily Married: To Dinah Lance.
- Like a Son to Me: In a deep contrast to canon, Quentin is fond of both Oliver and Tommy, to the point of seeing them as surrogate sons. Since Oliver never dated Laurel and/or broke her heart by cheating on her with Sara, Quentin has no reason to hold grudge against him. It's to the point that he holds nothing against Tommy for Malcolm's actions.
- Papa Wolf: To his daughters Laurel and Sara. When the Undertaking was revealed to the public, he didn't hesitate to go charging into the Glades to protect Laurel, despite knowing the place could be destroyed any second.
Dinah Drake Lance
The matriarch of the Lance family and mother of Laurel Lance and Sara Lance, Dinah is a professor at Balliol College, and a close friend of the Queens.
- Bit Character: She doesn't have much of a presence in the story.
The youngest child of the Lance family and younger sister of Laurel Lance, Sara was also greatly hurt by the death of their childhood friend Oliver Queen. She was on a dark path until the intervention of her father set her straight, and becomes a traveling humanitarian after graduating from college.
Officer Iris West
The oldest child of the West family, sister of Wally West, and the childhood best friend of Barry Allen. Barry's assumed death crushed Iris, and continues to influence her life to the present day. Just when it seems she's finally got it all under control, however, Barry comes back into her life, and suddenly everything, including Iris herself, begins to change.
- Adaptational Badass: Journalist in canon, cop here. As the author lampshades, though she won't be leading Team Flash anytime soon, she's actually more capable of it than she is in canon.
- Adaptational Personality Change: Tougher and (at first) somewhat harsher than her canon self, due to her losses.
- All of the Other Reindeer: During high school, thanks to a combination of emulating Barry and becoming an Ice Queen.
- Calling Parents by Their Name: Addressed Joe either by his first name or by "Detective West" after she joined CCPD's 1st Precinct. It takes a while for her to start calling him "Dad" again.
- Composite Character: Shes basically a mix of her Earth-1 and Earth-2 counterparts, particularly by being a cop like the latter.
- Dark and Troubled Past: Her best friend went missing and was presumed dead for ten years; while he was gone, she despaired over his death so much that she started acting like him, which got her ridiculed by all her peers just like he was. Plus, she learned her father had been lying to her all her life about her mother, and then learned that she had a little brother. One can't really blame Iris for being so cold and bitter as an adult.
- Defrosting Ice Queen: After Barry returns from Lian Yu.
- Dude Magnet: Even during her high school days; in fact, according to Tony Woodward, her Ice Queen status only made her even more desirable to the boys at school.
- Fair Cop: Every unattached, hot-blooded male in the precinct has a thing for Iris, even after she got together with Eddie.
- I Have No Father: Iris effectively disowned Joe after high school — when they started working together at the precinct, she only addressed him as "Detective West". Barry's reappearance is what finally pushes them to mend their relationship.
- Straight Man: Barry's when Oliver and Kara are around. She's the only one besides them that can keep his gadfly tendencies under control.
- Unresolved Sexual Tension: Even though she's in a relationship with Eddie, her and Barry have this going on; Iris is just oblivious to the dynamic (much like in canon), while Barry is aware to an extent but refuses to pursue it out of respect for her happiness.
- Used to Be a Sweet Kid: Iris was much warmer as a child, but after Barry's death, she was just never the same. She begins to return to her old personality when Barry returns.
- Wrong Guy First: Her relationship with Eddie, as outright stated by the author in the first chapter. The cracks are already beginning to show in Arc II.
Detective Joseph "Joe" West
The Patriarch of the West family, father of Iris and Wally West, and the foster father of Barry Allen. Joe has carried the guilt of his foster son's death for ten years, only amplified by his estrangement with his daughter and learning of his biological son's existence. Barry's return proves to be the light of at the end of the tunnel, and Joe finally finds it in himself to mend all those broken bridges, one at a time.
- Guilt Complex:
- Joe has been continuously hard on himself ever since his Parting Words Regret led to Barry washing up on Lian Yu, a situation only exacerbated by Iris' cold treatment of him. Barry is constantly exasperated by it, as, having significantly matured during his time away from home, he doesn't blame Joe for any of it. He doesn't even blame Joe for his father's incarceration anymore, a fact he reiterates when Henry is finally released from Iron Heights.
- It rears its head again at Henry's party, as he had unintentionally imprisoned an innocent man, which was only compounded by what happened to Barry. Henry is the one to help him get over it this time, making it clear that he only blames Wells for what happened and that he's grateful to Joe for taking Barry in.
- Parting Words Regret: He and Barry got into an argument one night about his father's innocence, resulting in Joe calling Barry "crazy" in the heat of the moment. He immediately regretted it and tried to take it back, but it was too late — it's what convinced Barry to go to China, leading to his ten-year disappearance.
- Reasonable Authority Figure: He's a just police officer and tries his best to be a good father.
Thomas "Tommy" Meryln
The son of Malcolm Merlyn, and the best friend of Oliver Queen. Tommy's life took a sharp downturn after Oliver's disappearance, and after a few years of being Starling City's premier party boy, his father cut him off from the family fortune until he cleaned up his act. Now a top executive at Merlyn Global, Tommy is initially overjoyed to see his best friend alive, only for that to gradually change when Oliver begins to overshadow him.
- Butt-Monkey: Life hasn't been really kind to Tommy. The woman he's crushing on is in love with his best friend, everyone he knows seems to be shipping them together, his own father seems to like said best friend more than he does him, and he gets shot twice in one arc.
- Dogged Nice Guy: To his friend Laurel.
- Heterosexual Life-Partners: With Oliver, though their relationship gradually strains as the story goes on.
- Green-Eyed Monster: Towards Oliver after his return, when Oliver catches the attention of both his crush Laurel and his father Malcolm.
- Heroic BSoD: After his father's evil deeds are exposed to the public.
- Took a Level in Jerkass: Other than the occasional Green-Eyed Monster moment, Tommy is a genuinely Nice Guy. At the start of Arc III, however, he gradually becomes more inconsiderate of the people close to him and less polite to others. It's implied that whatever Malcolm used to save his life at the end of Arc II was responsible.
- "Well Done, Son!" Guy: And his mended relationship with his father has only made it worse.
The biological father of Barry Allen. Henry was incarcerated after being framed for the murder of his wife, Nora Allen. Three years later, he attempted suicide after his son's disappearance, only to be foiled and put on suicide watch. Henry slowly regained the will to live thanks to the efforts of Iris West, which is eventually rewarded when Barry is found alive ten years later.
- Happily Failed Suicide: Barry was his Living Emotional Crutch, so when he disappeared and was presumed dead, Henry tried to commit suicide; he was stopped, and ten years later it becomes this when Barry returns to Central City.
- Living Emotional Crutch:
- To his son, and vice versa. When they finally meet each other again after ten years, Barry admits that one of the things that kept him going was his father, and how he had to get Henry out of prison. Knowing that, Henry can't find it in himself to protest Barry's attempts to get him released.
- He and Iris shared a similar relationship during the ten years Barry was gone. Henry served as a surrogate father figure to her after her relationship with Joe fell apart, while Iris actively visited him to help him regain the will to live, knowing Barry wouldn't have wanted him to die before he got out.
- Nice Guy: Every one of his appearances paints him as a genuinely kind man, one who holds no blame against Joe despite being unfairly imprisoned. It's implied that when he finally gets out of jail, even the guards are happy for him.
- Throw the Dog a Bone: When he's finally reunited with Barry after ten years spent believing his child dead, the prison staff decides to bend the visitation rules to let them embrace each other.
Samantha "Sam" Arias
A successful businesswoman residing in Starling City, and the mother of Ruby Arias. On a seemingly normal day of school, Sam finds her daughter talking with a new friend, and finds herself befriending the guardian of that friend: Kara.
- Adult Fear: She's violently shaken when Malcolm Merlyn is publicly unmasked as the mastermind of the Undertaking, since she had invited him to her daughter's birthday party.
- Foregone Conclusion: She is destined to one day become the supervillain Reign. While it's never outright stated, the author's notes alludes to it several times, and is ultimately why the author put a kibosh to a potential Sam/Kara pairing.
- Heterosexual Life-Partners: Quickly develops this dynamic with Kara, echoing the friendship between their respective charges.
- Sitcom Arch-Nemesis: Has one in Isabel Rochev, who is a former classmate of hers.
The daughter of Samantha Arias and a student at Balliol Prep. Ruby is intrigued when a new student enrolls into her class. Noticing how shy and withdrawn he is, she takes the initiative to speak with him, unwittingly befriending a boy whose secrets are far beyond her wildest imagination.
- Cheerful Child: Overall pretty upbeat and happy.
- Satellite Character: Mainly defined by her interactions with her mom and Kal.
- Ship Tease: Thea suggests the possibility of something going on between her and Kal when they first meet. Kara immediately shoots it down, pointing out that they're only twelve.
J'onn J'onzz | John Jones
The Last Son of Mars, whom the heroes free from imprisonment.
- Big Eater: Like Kara, he enjoys his cookies.
- Dark and Troubled Past: Lost his entire species to the Dominators, then was imprisoned on Earth for a decade.
- Doomed Hometown: There's a reason he's called the last son of Mars.
- Psychic Powers: A skilled telepath, at least.
- Socially-Awkward Hero: Has trouble fitting in on Earth, at least at first, thanks to being from another planet.
- Trademark Favorite Food: Oreos, what else? Kara even worries about him not having a healthy diet.
- Voluntary Shapeshifting: Can easily shift between human and Martian form, and most likely others as well.
League of Assassins
Nyssa al Ghul
A member of the League of Assassins, daughter of Ra's al Ghul, and Heir to the Demon. On a mission for her father, Nyssa saves four souls from drowning, forever tying her life to theirs.
- Badass Normal: Duh.
- Everyone Can See It: It was wildly speculated amongst League members that there was a relationship between her and Oliver, because of how close they were. However, most were smart enough not to ask Oliver about it.
- Honorary True Companion: To the Lian Yu survivors.
- Out of Focus: In Arcs I and II, as the League is primarily a background presence during those events. She's slated to return in Arc III.
- Unresolved Sexual Tension: With Oliver.
Ra's al Ghul
Leader of the League of Assassins, and the father of Nyssa al Ghul. A warrior that has hid himself among shadows for several centuries, when his daughter returns from Lian Yu, she brings along a child and three potential recruits, whose abilities test the limits of even his wide worldview.
- Badass Normal: With the possible exception of Oliver, he is the Badass Normal and the World's Best Warrior.
- The Dreaded: Even with Kara's abilities, none of the leads have any desire to anger him or make enemies with the League. In fact, they had initially planned to leave the League five years later than they did in the story, as by then, Nyssa (hopefully) would've succeeded him as the Demon's Head. Barry gaining his speedster abilities and whispers about the Undertaking forced them to move up their timetable.
- Evil Mentor: Well, it's more like "Extremely Morally Ambiguous and Mysterious Mentor", but "Evil" works just as well in the grand scope of things. He served as this to all three leads, and had a direct hand in shaping their morality as a result. It's only after they finally manage to separate themselves from his control do they start to realize and recover from the mental damage he's done to them.
- Noble Demon: While the Lian Yu survivors respect him to an immense degree and don't doubt his honor, they are not blind to what kind of man he is.
- Reasonable Authority Figure: When his most powerful warriors ask to take their leave, he gracefully accepts their resignation, only assigning them a last mission as compensation.
- World's Best Warrior: He's tied with Oliver for best "normal" combatant in the story.
The Director of Advanced Research Group United Support, better known as A.R.G.U.S. A woman who clawed her way up from the gutters of Chicago, Amanda Waller is utterly ruthless in eliminating threats against American interests, and it isn't afraid to use immoral and illegal means to get what she wants.
- How she forced Slade to join Task Force X during the ten-year Time Skip.
- It's also how she forces the main trio into a tentative alliance as her personal public Super Team; if Amanda dies by their hands, Slade automatically goes to the top of America's Most Wanted List.
- She forces Malcolm to absolve the Queens of any involvement in the Undertaking by implying she won't hesitate to dish a nasty fate for Tommy and Oliver.
- Can't Kill You, Still Need You: Part of why the leads have yet to kill her is because the resources she has at her disposal are too useful to their operations.
- The Chessmaster: While the three leads are cunning in their own rights, their focuses and goals are considerably small in scope. Amanda is the one who sees the big picture and plays everyone accordingly to a major aim. The Justice League, for example, is just her pet team of vigilantes whose purpose is to soak up the spotlight, providing proficient distraction so her black ops teams, specifically Task Force X, can operate undetected.
- I Gave My Word: She's very big on favors and their repayment. When Wade Eiling's manipulations ruined her chance to settle her debt to Nathaniel Adam, she was so pissed she decided to help his fiancee to screw him up.
- Jerkass: A horrible woman who makes zero apologies for it.
- Manipulative Bitch: And damn proud of it.
- Nerves of Steel: Even when confronting a metahuman able and willing to snap her neck in a millisecond, lady just won't twitch. Mainly because she always makes sure to hold the cards she needs to come out on the top.
- Noodle Incident: She owed a favour to Nathaniel Adam, but never was able to pay it before his untimely death. Man, was she irate about it.
- Red Baron: "The Wall".
- Slasher Smile: When she's grinning, people feels their hairs stand on their neck and compare her to the Devil.
- Start of Darkness: Her introductory chapter in Chapter 18, which reveals her past in Chicago and how it shaped her into the woman she is today.
A senior agent of A.R.G.U.S. and field commander of Task Force X. Maseo, his wife Tatsu, and their son Akio ran afoul of the Yakuza in Japan and fell under the employ of Amanda Waller for protection, eventually crossing paths with a man who would change their lives, for better and for worse.
- Adaptational Heroism: Since Akio never died, Maseo never left Tatsu to join the League of Assassins, and is a staunch ally of Slade, and by extension, the leads, in the present day.
- I Owe You My Life: Or more specifically, my son's life, which is why he is so loyal to Slade.
- This Is Gonna Suck: His reaction when China White joined Task Force X. Apparently she hadn't forgotten him at all, nor all the trouble he caused her in Hong Kong.
- Token Good Teammate: To Task Force X, alongside Slade and later Bette Sans Souci.
Francisco "Cisco" Ramon
A brilliant mechanical engineer for S.T.A.R. Labs, Cisco had a bright future ahead of him — only to lose it all when the Particle Accelerator exploded. One year later, Cisco still works for S.T.A.R. Labs out of loyalty to Dr. Harrison Wells, the man who gave him his big break.
- Be Careful What You Wish For: Played for Laughs when he gets a stern teacher in the form of Barry, who puts him through harsh lessons in hand-to-hand combat (though unknown to Cisco, this is still much nicer than the Training from Hell Barry received).
- Boxing Lessons for Superman: Barry gives him some when his powers start coming through and he expresses the desire to become a vigilante.
- Demoted to Extra: He and Caitlin are both Out of Focus due to Barry not being reliant on them like he was in canon.
- Pop-Cultured Badass: Very knowledgeable about pop culture, and getting there on the badass.
- Serious Business: Pop culture awareness. He was horrified to learn that Barry had lost out on ten years of pop culture references.
- Vitriolic Best Buds: Slowly becoming this with Barry, though it's taking a while due to Barry having a huge amount of secrets.
A bioengineer working at S.T.A.R. Labs, Caitlin's life fell apart thanks to the Particle Accelerator Explosion, which took the life of her fiance, Ronnie Raymond. Listless since then, the monotony of her life is broken when her boss unexpectedly hires a new face.
- Defrosting Ice Queen: Even icier to Barry than in canon thanks to the latter being morally ambiguous and extremely secretive. She begins to soften on him when he helps her reunite with Ronnie.
- Demoted to Extra: She and Cisco are both Out of Focus due to Barry not being reliant on them like he was in canon.
- Only Sane Man: Often the mediator between Cisco and Barry.
Ronald "Ronnie" Raymond / Firestorm A
A former structural engineer for S.T.A.R. Labs, Ronnie was presumed dead after the Particle Accelerator Explosion, his body disintegrated in the resulting blast. (Un)fortunately, the truth is far more complicated.
- Spared by the Adaptation: Does not die at the end of the story's equivalent to The Flash Season One.
Martin Stein / Firestorm B
A professor at Hudson University and a leading expert in thermodynamic physics, Martin visited S.T.A.R. Labs the night of the Particle Accelerator Explosion to acquire backing for his research, along with a certain briefcase to validate his line of study. Martin would disappear that night, along with his briefcase, and the truth of his vanishing will come back to haunt those he left behind.
- Demoted to Extra: Since the Legends will never form in this timeline, Stein is demoted to recurring character instead of being a lead like he was in canon.
Mari Jiwe McCabe / Vixen II
An aspiring fashion student from Detroit. All her life, Mari has searched for where she came from, and found her answers upon her return to Detroit. Now a vigilante empowered by the Anansi Totem, Mari finds that her family holds even more secrets than she initially thought.
- Legacy Character: To her grandmother, the first Vixen, Amaya Jiwe.
- Out of Focus: Of the four members of the Justice League, she is by far the least focused on. Somewhat justified in that she has her own area of responsibility up in Detroit, and doesn't work too much with the others unless it's something major.
- Race Lift: Slightly. In canon, Mari and Kuasa are of pure African descent. Here, they are one-fourth Caucasian due to their grandfather being the Caucasian Rex Tyler.
- Related in the Adaptation: In canon, her and Kuasa's grandfather is an unidentified man from Zambezi. Here, it's Rex Tyler, leader of the Justice Society of America.
Other Supporting Characters
Detective Edward "Eddie" Thawne
A police detective, recently transferred from KCPD to CCPD and the partner of Detective Joe West. Son of the influential Thawne Family, Eddie transferred to the CCPD to escape his family's shadow and make his own mark. Of course, working with the gorgeous Iris West helped softened the blow. One year later, Eddie has got it all; a life away from his stuffy family, a rewarding job, and a beautiful girlfriend — only for all that to be threatened when a vigilante that embodies the impossible starts appearing in Central City, and Iris' childhood friend returns from the dead.
- Ascended Extra: While Eddie was by no means a minor character in canon, in this story he's designated to become a major character, and the author has continuously stated that they have plans for him.
- Adaptational Personality Change: Eddie is much more antagonistic than his canon counterpart, both to Barry and the Flash. The former because of Barry's own Adaptational Personality Change, which causes Eddie to perceive him as more of a threat to his relationship with girlfriend Iris, and the latter because he is darker and more brutal than the canon!Flash.
- Adaptational Jerkass: See above. Justified, again, by Barry's own personality change and the circumstances surrounding his disappearance, which have impacted Iris' personality and overall life far more than his canon coma did.
- Black Sheep: Implied to be this to the Thawne family.
- Green-Eyed Monster: To Barry, mainly because Iris is much more open around him than she was with anybody else, including Eddie.
- Humiliation Conga: First, he continually fails to catch the Flash. Then, Iris leaves him over his single-minded focus on the Flash. Then he gets beaten up by the Flash even with his anti-speedster weapon, the police shut down the anti-Flash investigation, and he gets demoted from leading the task force. And even when Iris does agree to renew their relationship, she leaves his apartment because she feels she needs space.
- Inspector Javert: To the Streak/Flash, with Barry even name-dropping the Trope Namer. He's absolutely furious when the hunt for the vigilante is called off in the aftermath of the Undertaking.
- Spared By Adaptation: Like Ronnie, survives the story's equivalent to The Flash Season One.
- Stalker Without a Crush: To the Streak/Flash.
- Sympathetic Inspector Antagonist: Initially, as while the Streak/Flash has good intentions, it doesn't change the fact that he's subverting the law and murdering people. The sympathy decreases as his obsession with the Streak/Flash grows, however, and it begins to affect his personal life.
- Workaholic: After he starts chasing after the Streak/Flash. It gets so bad that he and Iris even briefly break up over it.
Detective Ralph Dibny
A police detective for the CCPD and coworker of Eddie, Joe, and Iris. Ralph is a competent investigator, but it's mitigated by his obnoxious and perverted personality.
- Ascended Extra: Of a sort; he appears far earlier than he does in canon, because Barry never busted him for tampering with evidence. That being said, thus far he's remained a background character.
- Bunny-Ears Lawyer: Iris walks in on him making paper airplanes with their collective paperwork, and he's a definite Casanova Wannabe. However, in the true spirit of the trope, he's tolerated because he's also one of the best detectives that they have.
- Casanova Wannabe: Eddie and Iris note that not a week goes by without some woman entering the precinct to slap Ralph.
- Hopeless Suitor: To Iris; even if she wasn't dating Eddie, she wouldn't give Ralph the time of the day.
- The Friend Nobody Likes: The entire precinct. It's all but stated that nobody likes Ralph, and only put up with him because, despite his many, many flaws, he's a damn good detective.
A neurosurgeon and a member of Starling City's wealthy elite. Carter is rich, brilliant, and incredibly arrogant, which does not endear him to many, including his old classmates and their friends.
- Abhorrent Admirer: Unfortunately for Kara, he doesn't get the hint she's not looking for a relationship.
- Hopeless Suitor: To Kara. Her disinterest in romance is one reason, but it's hardly the only one.
- Nouveau Riche: His family is implied to be new money.
- Small Name, Big Ego: Downplayed. While Carter is a member of Starling City's elite and he has a number of significant accomplishments to his name, his family's pedigree is still nowhere near comparable to the Queens or the Merlyns. The narrative notes that the Bowens have to pull a lot of strings to get their progeny into Balliol; compare that to the Queens and Merlyns, who get theirs in on name and legacy alone.
- Social Climber: Implied, as an extension of Small Name, Big Ego above; it's insinuated that the reason Carter is so interested in Kara is because of her close association with the Queen family, particularly Oliver and Moira.
The daughter of mob boss Frank Bertinelli, Helena waged a one-woman war on her father's criminal enterprise, heedless of the collateral damage. (Un)fortunately for her, others weren't, and she was offered a deal she couldn't refuse.
- Adaptational Badass: Joins the League of Assassins.
- An Offer You Can't Refuse: Either give up her vendetta and take a chance with Ra's al Ghul in hopes of joining the League of Assassins, or go to jail alongside her father (who will be taken down no matter what choice she makes). It doesn't take a genius to figure out what Helena chose.
- Sympathetic Villain: Tried to kill her father, but that was because he murdered her fiance.
- Put on a Bus: So far, hasn't been seen since she joined the League.
Malcolm Merlyn / Al Sa-Her / The Dark Archer
The father of Tommy Merlyn, CEO and Chairman of Merlyn Global, former member of the League of Assassins, and leader of the criminal cabal known as Tempest. Twenty years prior to the present storyline, Malcolm lost his wife in a mugging in the Glades, and has never managed to move past it, eventually crafting together a terrible plot to destroy the Glades in retaliation for her death. For the sake of this plan, Malcolm has committed a number of crimes and destroyed more than one friendship to keep things on track — however, his mettle will be put to the test when a hooded vigilante starts looking into his alter-ego.
- Adult Fear: A bit of this when he subtly tries to discourage Oliver to work on renewing the Glades. Doing this took his wife's life, and now it threatens his son's.
- Arch-Enemy: To the Hood / Green Arrow. His relationship with Oliver is far more complicated.
- Archnemesis Dad: Neither he nor Oliver is aware of this little fact. Oliver only knows his godfather is a criminal who ruined his life, while Malcolm couldn't manage to unmask the Hood and as such only knows Oliver as his illegitimate son.
- Badass Normal: Gives Oliver a serious fight, though definitely not at his level.
- Cannot Spit It Out: Non-romantic version. He wants to tell Oliver that he is his father, but can't due to Robert and Moira forbidding it. That being said, Malcolm has been close to telling Oliver several times already but just can't seem to say it.
- Control Freak: He's really unhappy when his plans go awry and pratically throws tantrums when the Queens oppose him. Downplayed with his attempt to steer Oliver's business project away from the Glades — he's obviously distressed by Oliver's persistence but doesn't press.
- Even Evil Has Loved Ones:
- For all his faults, Malcolm genuinely loves Tommy.
- He also deeply regretted causing the "death" of his godson Oliver, and was relieved when Oliver turned up alive. That fondness turns into love when he learns that Oliver is his biological son.
- Laser-Guided Karma: He destroyed Oliver's life by making him a castaway for ten years, and Oliver repays the favor by thwarting the Undertaking. Even before, almost killing Oliver had a component of this, due to their blood relation. And after, it means a scheme to avenge his beloved wife is ruined by the son he favours.
- Luke, I Am Your Father: To Oliver.
- My God, What Have I Done?: He never intended for Oliver to be lost at sea for ten years. The feeling comes back with a vengeance when he learns Oliver is actually his illegitimate son.
- Never My Fault: Blames the Hood for Tommy being shot, even though it was Malcolm's fault that Tommy was put in that situation to begin with.
- Oh, Crap!: When he realizes that the Hood not only recognizes him as a member of the League of Assassins, but is himself a member as well.
- Parental Favoritism:
- He's much more supportive and encouraging towards his godson Oliver than his own son Tommy. Guilt is implied to be a huge factor in his behaviour. Then he learns his blood relation to Oliver...
- Notably, Malcolm never acknowledges his failures as Tommy's father. With Oliver, however, he never tries to excuse his past behavior and actions, and does everything short of giving up the Undertaking to make it all up to him.
- Villain Forgot to Level Grind: Lampshaded in the author's notes. While Malcolm is a genuinely dangerous individual, his combat level is significantly below the three leads (even without their powers), especially Oliver's, due to being older and only having two years of training. While Malcolm trains enough to maintain his current level, he has no one to push him to be even stronger like Oliver does with Barry and Kara and vice versa.
- "Well Done, Dad!" Guy: To his illegitimate son, Oliver. Originally it was subconscious and manifested as Parental Favoritism over Tommy, stemming from his guilt over essentially ruining Oliver's life. These impulses then became conscious and more pronounced after learning of their blood relation, and Malcolm takes more proactive attempts in steering Oliver's life to keep him safe.
Eobard Thawne | False Harrison Wells / "The Man in the Yellow Suit" / The Reverse-Flash
An time traveler from the future and the arch-nemesis of the superhero known as the Flash, Eobard was stranded in the twenty-first century after he murdered Nora Allen to prevent her son from growing up to become his greatest enemy. Desperate to return to his time, he killed the original Harrison Wells, taking on his appearance and identity to accelerate the creation of the Particle Accelerator, and thus, the birth of the Flash.
- Arch-Enemy: To Barry Allen.
- Faux Affably Evil: Loses his polite demeanor when things don't go his way.
- Foil: To Astra and Malcom. Of the three main villains of Arcs I and II, Thawne is the only one who has no genuine fondness/love for his adversary — the closest he gets is grudging respect for Barry's intellect. He knows far more about what's going on with the three vigilantes than arguably the vigilantes themselves do; contrast that with Astra, who only ever found out about Kara working with the Streak/Flash, and Malcolm, who was completely blindsided by Oliver working with other vigilantes, figuring that he was just an agent of the League of Assassins. Finally, he's the only villain to never be completely defeated by his enemy — the three vigilantes and Firestorm all ganged up on him to capture him.
- Even Evil Has Standards: Even he has a poor opinion of Twilight.
- I Know You Know I Know: Was posed to have this situation with Barry, who knew that Eobard knew that Barry was the Flash. Barry then decided that would be a waste of time and revealed his identity to Eobard, Caitlin, and Cisco straight off the bat instead.
- Manipulative Bastard: The man manages to use the location of his hideout as a psychological weapon. Manipulative doesn't even begin to cover it.
- The Worf Effect: In their first fight, Barry manages to hold his own against him, but it became increasingly clear that he was outmatched; if it hadn't been for Eobard's speed shorting out, Barry would've assuredly lost.
- Worf Had the Flu: In one comment, the author explicitly calls him the most dangerous of the three main antagonists of Arc II, and rightfully so. He only tied with Barry in their first fight because his speed shorted out, and lost his second fight after being essentially ganged up on by the World's Best Warrior, two of the strongest metas on the planet, and a fully-trained Kryptonian, and even then it was a close thing. He didn't even lose the third fight. A portal literally appeared out of nowhere and sucked him in before there could be any real resolution to the conflict.
General Astra In-Ze
Imprisoned in Fort Rozz by her twin sister, Astra survived the destruction of her planet alongside her husband and a number of their subordinates. Landing on Earth, she found another planet that was in desperate need of saving, and continued what she could not on Krypton in the memory of the family she had lost — especially her niece, Kara. Ten years later, she finds her determination shaken when a disguised woman bearing the crest of the House of El starts appearing on the news.
- Adult Fear: Astra spends years mourning her niece's supposed death, alongside their people. Years later, she finds said niece alive...as a ruthless killer. One can't really blame Astra for being so distressed when she learns and finally accepts the truth.
- Arch-Enemy: To her niece, Kara Zor-El.
- Broken Pedestal: A two-way example. Kara is disgusted when she learns about Astra's plans (and the fact that she had initially planned to do the same to Krypton before Alura imprisoned her), while Astra is horrified to learn about what kind of person Kara has become.
- Even Evil Has Loved Ones: Despite being on opposing sides, Astra still loves Kara, and spends most of Arc II planning to sway her niece to her side.
- Green-Eyed Monster: She really doesn't like Moira assuming a motherly role towards her niece.
- Pet the Dog: She may despise the House of El for their foolishness and goody-two-shoes idealism, but she prays for their souls after realizing they managed to save her beloved niece from Krypton's destruction. Also, she's willing to leave Kal-El alone, on the grounds that Kara loves him and he's only a child.
- Selective Obliviousness: Even after being explicitly told by her most trusted men, Astra almost outright refused to believe that her beloved Kara was a killer. She only accepts it after Kara kills Non.
- Spared by the Adaptation: She remains the Big Bad of Supergirl's storyline in Arcs I and II, and is spared by Kara at the end of said storyline out of sentiment.
- Stalker Without a Crush: She's very interested by any reports concerning Kara and outright spied on her twice — after believing her niece dead for so long, she treasures information about her and seeing her alive and well.
- Villainous BSoD: Gets one after Non is killed by Kara.
- We Can Rule Together: Kara correctly deduces that this is how she managed to get all the Fort Rozz prisoners to follow her. It's also brutally deconstructed by Kara, as she points that their idea of ruling differs from Astra's, and once they realized that, there would be no way they'd stand idly by.
- Well-Intentioned Extremist: Wants to save the Earth from using up their resources like Krypton did, but plans on using Mind Control to do it.
Husband of Astra and her second-in-command. Non, while not always faithful to his wife, is eternally devoted to her and her ideals. So devoted, in fact, that he does not hesitate to try and keep her own her chosen path when a girl thought dead pierces through her facade.
- Co-Dragons: To Astra, with Indigo.
- Demoted to Extra: Non was the Big Bad of Supergirl Season One after Astra was killed. Here, he remains her Dragon.
- Killed Off for Real: His fate in Supergirl was left ambiguous due to the show's change in network. Here, he was explicitly killed by Kara.
- Obviously Evil: At least according to Kara. Even as a child, Kara could sense the darkness within him, which is why she had no regrets in killing him as an adult.
- Unholy Matrimony: With Astra. He philandered on the side, but he genuinely admires her.
- Underestimating Badassery: He dismisses Kara as a threat constantly. This changes somewhat after Kara kills some of his subordinates, but it's only after fighting Kara himself does he realize what kind of threat she really poses, and is killed soon after.
Braniac 8 / Indigo
The most dangerous prisoner in Fort Rozz. A Coluan born of the Braniac Clan, Indigo is normally not one to take orders, especially when its the wife of a former flame. When involves ruling an entire planet, however, she's willing to play along — on her own terms, of course.
- Co-Dragons: To Astra, with Non.
- Logical Weakness: Indigo can travel to different locations via the Internet. Cutting the power of whatever room she's in effectively strands her unless someone has a smartphone handy.
- Working with the Ex: Her relationship with Non. It's not entirely clear if Astra was aware of their affair, however.
A former test subject for S.T.A.R. Labs and General Wade Eiling, Grodd disappeared the night of the Particle Accelerator Explosion like many others.
Originally a small-time fence for Central City's criminal underground, the Particle Acceleration Explosion granted her the ability to manipulate magnetism, particularly over the alnico alloy. Amunet used this ability to become the top arms dealer of Central City, and is now looking to expand her horizons elsewhere — without attracting the attention of the Flash.
- Masquerade: Amunet deliberately keeps her status as a meta on the downlow so she won't attract the attention of the Flash, who specifically targets metahuman criminals. Most of the Central's criminal community abides by her wishes, as they don't want to risk the Flash finding her and crippling crime even more than he already has by taking her out.
- Villainous Friendship: With the Snarts, being their original fence for stolen goods before she struck out on her own.
The premier thief of Central City, Snart's life hasn't changed all that much since the Flash came along — until a run of bad luck changes that.
- Adaptational Personality Change: Unlike canon!Snart, this Snart actively avoids the Flash, due to the latter being far more brutal and far more willing to kill. Since the Flash only bothers to kill dangerous metas however, Snart is technically in the clear, but that doesn't mean he's willing to push his luck as far as that is concerned.
- Properly Paranoid: After bad luck causes him to be captured by the Flash during one of his searches for the Reverse-Flash, Snart commissions the Cold Gun from Amunet in Arc III so that way he has some insurance in case he runs into him again.
- Villainous Friendship: With Amunet Black.
The former lover of Robert Queen and a successful businesswoman in her own right. Isabel has never forgiven Robert for breaking up with her and firing her from Queen Consolidated, and has been plotting her revenge ever since. A month after the Undertaking, she returns to Starling City to aid in the restructuring of Merlyn Global, and serves as an ominous sign for the future.
- Bitch Alert: Her first appearance in the story has her completely ignoring The Palm's chauffeur, shoving him away when handing over an arbitrarily large tip.
- One Degree of Separation: She is an ex-classmate and rival of Sam's. In fact, Sam was the one she beat out for the internship at Queen Consolidated.
- The Resenter: Isabel has never gotten over the fact that Sam managed to start and head her own successful company before she could, and it's colored their dealings with each other over the years.
- Sitcom Arch-Nemesis: To Sam.
- Woman Scorned: Which is why Robert and Moira are unsettled at her reappearance. They know she isn't just here for Tommy's sake.
Tony Woodward / Girder
The childhood bully of Barry Allen and Iris West, who gained the ability to turn into steel after falling into a vat of melted steel the night of the Particle Accelerator Explosion.
