Team Arrow
Moira Queen/Green Arrow
- Action Mom: She's the mother of Oliver and Thea Queen, and is also the vigilante known as the Green Arrow.
- Adaptational Badass: While she's a completely ordinary woman in the main Arrowverse, she's a Badass Normal in peak condition for her age here.
- Mama Bear: If you want to stay alive, DO. NOT. Threaten Oliver or Thea.
- Parental Substitute: Overlaps with her role as Team Mom, but she serves as one in particular for the orphaned Helena, comforting her in times of trouble and offering advice.
- Team Mom: Justified, as one of her teammates, Thea Queen/Red Arrow, is her daughter.
Thea Queen/Red Arrow
Nyssa Al Ghul
- Adaptational Heroism: In the comics, she's an extremist villain. Arrow made her more sympathetic, but she still started off as a villain. Here, Nyssa genuinely believes the League is evil and is trying to disband it- but has a genuinely good relationship with Talia, has a strict moral code, and is unambiguously good-aligned (though she falls under Good Is Not Nice and Good Is Not Soft). Interestingly enough, despite having been fully trained as an assassin, she only kills in self-defense or to protect others.
- Adaptational Sexuality: She's a lesbian in the main Arrowverse, but here, she's bisexual.
- Thou Shalt Not Kill: Though she's trained as an assassin, she refuses to kill her enemies unless it's the only way to protect herself or others.
Helena Bertinelli/Huntress
- Adaptational Heroism: A circular example. She's a hero in the comics, but Arrow portrayed her as a villain, albeit a sympathetic one. Here, she's once again a heroic character.
- Good Is Not Nice: Unlike some of her teammates, she has no qualms about using lethal force.
Cindy/"Sin"
- Batter Up!: Her weapon of choice is a baseball bat wrapped with an old bicycle chain, which she calls "Lucille".
- Boyish Short Hair: She keeps her hair in a short pixie cut.
- I Call It "Vera": She has named her baseball bat "Lucille".
- Only One Name: She grew up without parents, so her first name, Cindy, is the only name she has.
- Pop-Cultured Badass: Implied; she's a fan of The Walking Dead, made obvious by her weapon of choice.
- Tagalong Kid: She's the only teenager on the team.
Laurel Lance/Black Canary
- Masculine Girl, Feminine Boy: She and Oliver are a downplayed example; he's particular about his appearance and frequently ends up as a Distressed Dude, while she's rather pugnacious and tends to keep her emotions bottled up.
- Parental Substitute: To Sin, who views her as a mother figure. Eventually, Laurel officially adopts her.
The Shadowhunters
More or less counterparts for Justice Leauge Dark and similar teams. These people deal with all sorts of supernatural disturbances.
John Constantine
- Battle Couple: With Siobhan.
- Beast and Beauty: He and Siobhan are a gender-inverted example of this. She's very protective of him, and he's able to bring out her softer side despite her scary appearance.
- Deadpan Snarker: He has a sarcastic comeback for virtually everything.
Siobhan Smythe/Silver Banshee
- Adaptational Backstory Change: In the comics, Silver Banshee's powers and appearance are the end result of a Deal with the Devil (or in this case, a supernatural entity called the Crone). Here, they're the result of a hereditary curse, which afflicts women in her family line every three generations. (Her great-grandmother, Ciaran, was the last one affected by it.)
- Adaptational Heroism: She's a villain in the comics and in Supergirl (2015). Here, though she's not overly nice, she's a hero.
- Bad Powers, Good People: She has a sonic cry that can cause instant death if she knows the target's name. She's also a heroic character here.
- Battle Couple: With John Constantine.
- Horrifying Hero: She has permanent facial markings that make her face look like a skull, tangled white hair, and a deadly sonic scream. There are times when she speaks with the Voice of the Legion. She's still on the side of good, though she's not easy to get along with.
- Psychic Powers: In addition to her scream, she also has telekinetic abilities. Additionally, in an allusion how mythological banshees wail in anticipation of a person's death, she has mild precognitive abilities, though she can't control them and can only see a few minutes into the future.
- Violently Protective Girlfriend: If you value your life, don't threaten John Constantine around her.
Tatsu Yamashiro/Katana
- Crusading Widow: As usual, she's inspired to start her crusade after the death of her husband and son.
- Sophisticated as Hell: Frequently mixes formal speech with modern slang. Siobhan thinks it's hilarious.
S.T.A.R. Labs Crew
A group of three heroes with no official name as of now. Cisco's working on coming up with something. The two founders, Caitlin Snow and Cisco Ramon, are a married couple who originally met in a support group for autistic adults.
Caitlin Snow/Frost
- Battle Couple: With Cisco Ramon.
- Beware the Nice Ones: She's an extremely kindhearted person with a fondness for cute things and a strong desire to help others. Do not underestimate her.
- Closet Geek: Cisco is one of the only people who knows that she still plays Pokemon.
- Elemental Hair Colors: After her lab accident gives her ice powers, her hair turns white.
- Happily Married: To Cisco.
- Horror Hunger: Has an insatiable craving for body heat. It led to the people who captured her being frozen to death.
- Hospital Hottie: She's a very attractive scientist with a doctorate, and can perform medical procedures.
- An Ice Person: She gains these abilities after a lab "accident" turns her into a heat vampire.
- Pair the Smart Ones: She and Cisco are both regarded as rather intelligent.
Cisco Ramon/Vibe
- Adorkable: He can be rather awkward at times...which, particularly in Caitlin's opinion, only makes him more endearing.
- Battle Couple: With Caitlin, of course!
- Nerd Action Hero: He's both very intelligent (and admittedly a bit awkward) and a total badass.
- Pop-Cultured Badass: He'll even sometimes borrow Bond One-Liner-type lines when fighting.
- Understanding Boyfriend: He's accepting of Caitlin even after her condition emerges, and even huddles with her for warmth to prevent her sickness from getting too intense.
