This page is for listing tropes related to members of the organization known as the Justice League in the animated series Young Justice.
    open/close all folders 

  • Adults Are Useless: The incident with Red Tornado stands out as an example of where they should be far more competent, but otherwise they are pretty on the ball.
  • Back for the Finale: The six that were in Rimbor, Hawkman, Icon and the Green Lantern members that joined them.
  • Badass Crew: Actually subverted. Individually each League member is incredibly powerful, but they aren't a cohesive force like The Team is so their capabilities when working in groups tend to be somewhat underwhelming.
    • Which is Fridge Brilliance. The Team consider each other family, while the League are more like adults at work. Several of them are friends, but not in the same way.
  • Badass Teacher: Many of them are mentors towards The Team.
  • Big Good: The League itself, which the characters frequently mention as possible support when it looks like the situation is something they can not handle themselves. The League also has a rotating chairman who embodies the trope more then others.
  • Brainwashed and Crazy: At the end of Season 1, the entire League is taken over by Vandal Savage and Klarion.
  • Clear My Name: A variation. The "sixteen hours" (Superman, Batman, Wonder Woman, Martian Manhunter, John Stewart, and Hawkwoman) Leaguers leave Earth (with Hawkman, Hal Jordan, and Icon in tow) to do face charges in "Alienated". Although they actually did do it, they were actually Brainwashed and Crazy at the time.
  • Demoted to Extra: The entire team, since the series focuses their sidekicks. Cartoon Network even touted the show this way in early promos, counting on the audiences familiar with the Justice League cartoon to cause shock when the protagonists were revealed to be the children.
  • Elaborate Underground Base: Formerly operated out of Mount Justice.
  • Final Boss: The season 1 finale has the Team fight the entire league... and win. See The Worf Effect.
  • Hero with Bad Publicity: As of the second season, the entire League are wanted criminals in Rann space. This is because the Light sent a team of brainwashed Leaguers to their area of space and had them go on a rampage while broadcasting their identity.
    • Closer to home, G. Gordon Godfrey is running a smear campaign on the Justice League, particularly the alien members. It seems to be working.
  • Living Prop: Some members haven't received lines yet.
  • Loads and Loads of Characters: At least twenty-six members by the end.
  • Order Versus Chaos: Order to The Light's chaos.
  • Put on a Bus: The six Leaguers who were brainwashed into attacking Rimbor have now left to stand trial and prove their innocence. Accompanying them are Hawkman (who refuses to leave Hawkwoman) and Icon, who's acting as advocate.
  • Reasonable Authority Figure: Most of the League members who regularly interact with the Team are this.
  • Space Base: The Watchtower
  • Spiritual Successor: To the Justice Society of America, as usual.
  • Story-Breaker Power: Probably the reason why most of the League's strongest members get Put on a Bus to space early in season 2. Freely admitted by Greg Weisman when it comes to the League's two (in season two, three) Green Lanterns: they are frequently off world because they're so powerful that they should be able to neutralize just about anything, but also justified because they're responsible for protecting more than just Earth.
  • Two Girls to a Team: Although there are three female members on the team, which technically means it doesn't count, the full roster is sixteen members so the essential truth of this trope is still in play. Interestingly, Wonder Woman seems to be actively working against this, as one of her stated criteria for an ideal new member to the League is that they be a woman to help shift the gender ratio.
  • The Worf Effect: As stated above, the entire League is beaten by the Team in the season 1 finale. Justified by the fact that Klarion had to control all of them at once (therefore making it harder to make them each effective in battle), while the Team could take on one to a few at a time. Kid Flash comments on this to Artemis.

Superman (Kal-El/Clark Kent)

Species: Kryptonian
Voiced by Nolan North

The Big Blue Boyscout- though, perhaps a little less so than most interpretations. Though still the symbol for Truth, Justice and American Way, Superman was more than a little freaked out about the discovery of his clone, Superboy. He spent most of the first season avoiding any responsibility for him, despite the efforts of the rest of his colleagues to make him reconsider. He eventually accepts Conner as a little brother rather than a son come season 2.

One of the most powerful characters, with flight, super-strength, heat-vision and much, much more.

Note: Some of the tropes listed for Superman here are from the tie in comic, NOT the animated series itself, so don't be surprised if a few come off as Informed Attribute or All There in the Manual.
  • Adaptational Jerkass: Downplayed. Superman is still the All-Loving Hero Nice Guy but he acts quite aloof and distant to Superboy.
  • Adorkable: As Clark Kent, trying to get to know Conner. As soon as he's out of earshot, Conner calls him pushy.
  • All-Loving Hero: In theory at least, though not always in action.
  • Aloof Big Brother: Averted. When Superman chooses to consider Superboy as a younger brother, rather than being his father like everyone else wanted or refusing to interact as he wanted, he warms up to him quite considerably, even giving him a Kryptonian name and essentially adopting him.
  • Badass Cape: As per custom for every version of Superman.
  • Big Brother Instinct: He does not respond well to people trash talking him or attacking him.
    • In the tie in comics where Superman fried Brainiac with his heat vision for insulting Superboy.
    • He took a missile in the chest for Superboy in the season 2 episode Alienated.
  • Big Brother Mentor: To Superboy in Season 2.
  • Black and White Morality: Lex Luthor claims he has this.
  • Brought to You by the Letter "S": As with Badass Cape, it's Superman. You can't not have this trope.
  • Chronic Hero Syndrome: His refusal to leave the Kroloteans behind plants him in the middle of an explosion that can be seen from orbit. He survives, but Superboy knows that failing to save them means he still won't be okay.
  • Clark Kenting: Spectacularly done in the tie-in comics, where Clark tags along on Superboy and Miss Martian's mission. Miss Martian instantly recognizes him because she recognizes Conner's face despite his glasses and hat, and tells him so, explaining that Superboy doesn't because he doesn't keep mirrors and rarely sees his own reflection. Clark sheepishly explains that he wants the chance to get to know Superboy as Clark, not Superman.
  • Eye Beams: Superman's laser vision makes a return.
  • Flying Brick: As ever.
  • Heroic Build: Has an impressive muscular build and is obviously a hero.
  • Human Aliens: Kryptonians are superficially identical to humans.
  • Last of His Kind: He's apparently on the lookout for people who share his powers.
    Superman: I nominate Icon for League membership.
    Green Arrow: Why? Because you suspect Icon might be Kryptonian like you did with Captain Marvel?
    • He also Facepalms when the Collector of Worlds leaves before he can ask if he collected anything from Krypton.
  • Parental Substitute: Even though he rejected his "child" in the beginning, he counts as this to Superboy.
  • Primary-Color Champion: As per tradition, Superman still wears a blue uniform with his famous red-and-yellow "S" shield on his chest, red trunks, a yellow belt, red boots and a red cape.
  • Super Senses: Enhanced vision and hearing. Probably the other three as well, but the two main ones are those.
  • Super Speed: Although Weisman prefers "enhanced speed" - he's slower than Kid Flash who is slower than the other three speedsters.
  • Super Strength: Again, Superman. He can lift a bus into the air, which Superboy was struggling to lift (mainly because of poor leverage)
  • Red Is Heroic: Per usual for every version of Superman to wear a red cape.
  • Tall, Dark, and Handsome: Either as Superman or Clark Kent, he qualifies.
  • That Thing Is Not My Child!: Deconstructed. There's nothing particularly anti-clone about it and he doesn't actually dislike Superboy, but he's not happy when Batman calls him Superboy's "father". His rationalization is that Conner will do better with role models who don't have all their baggage. By season 2, he's comfortably referring to Conner as a little brother. Doubles as a Mythology Gag to the comics, where both the Silver Age and Clone Superboys were involved in a "Cool Big Brother" dynamic. Clark with Mon-El, Conner with Clark.
  • Took a Level in Kindness: In season 2, in which he accepts Superboy. Not that he was horrifically unkind before so much as too distant for his own good.
  • You Have Got to Be Kidding Me!: His reaction when he learns Lex Luthor took the credit for stopping the Reach and is now the favorite for "new secretary-general of the United Nations". It's actually quite funny.

Batman (Bruce Wayne)

Species: Human
Voiced by Bruce Greenwood

The Dark Knight of Gotham city. Like always, he's brooding and suspicious, but his caring nature is much closer to the surface than in most interpretations. He has a close relationship with the first Robin, Dick, and eventually takes the entire Team under his wing.
  • Adaptational Nice Guy: Compared to other incarnations where he's The Stoic, he's much more expressive here.
  • Animal Motifs: A bat, as usual.
  • Arson, Murder, and Lifesaving:
    • Pulls this one on the team in "Drop Zone".
    • And again in "Usual Suspects".
  • Badass Baritone: Has a deep voice and is Batman.
  • Badass Cape: He's Batman after all.
  • Badass Normal: To the point where he has the respect from, and authority over, beings with various superpowers even though he has none of his own.
  • Big Good: He’s the League Chairman in Season One. He may seem (and sometimes is) hard and strict on the team, but he ultimately praises them and encourages them to work together.
  • Brainy Brunette: Dark and and the Goddamn Batman.
  • Broken Pedestal: In "Disordered," Dick tells Black Canary that he'd always wanted and expected to be Batman when he grew up, but his stint as leader in "Failsafe" made him realize that he just can't be the obsessive, at-all-costs kind of person that Bruce is. "Agendas" shows that Bruce himself would be nothing but relieved by this.
  • Crazy-Prepared: He's Batman after all.
  • Dark Is Not Evil: Again, Batman.
  • Dating Catwoman: Talia al Ghul declares her love for Batman in issue #11 of the tie-in comic, while Batman is noticeably bothered by the fact that she's going to hate him because her father, Ra's, temporarily died during the fight.
  • Deadpan Snarker: Not in front of the team, but when it's just he and Robin on a mission:
    Ra's al Ghul: Why are our encounters always so... adversarial?
    Batman: Something to do with your disdain with human life.
  • Determinator: According to Robin, who's figured out it's not all it's cracked up to be.
  • Doting Parent: "Hmm, do I try to prevent my friend, the President of Qurac's assassination or do I go to my kid's birthday party? Well, Superboy and Miss Martian can handle the first one, right?"
  • Drill Sergeant Nasty: Subverted in "Drop Zone" where at first he appears to be furious that they made so many mistakes in their first mission, only to tell them that they did a good job.
    • It's particularly notable coming from Batman, who in several other media is very obsessive about his plans not going the way he originally wanted. Here, he first scolds them for not listening to his orders before praising them for reacting well once the situation changed. He even outright states that plans almost never survive first contact with the enemy. But even so, they are not to repeat the same mistakes if they can help it.
  • Dynamic Entry: Done this twice already, once in the pilot episode and then in "Downtime".
  • Expressive Mask: One can know if he's angry.
  • Good Parents: When noticing that Robin was jealous of the attention he was giving to Kaldur, Batman simply invites Robin for some basketball with him to assure him that no one would replace him.
  • Heroic Build: Muscular? Check. Hero? Double check.
  • Not So Stoic: In "Disordered," he makes a squirmy face when J'onn scolds him for overestimating the Team's ability to recover from the trauma of "Failsafe," and he sighs in disappointment when Superboy runs off without his radio. There's also "Agendas," where his voice becomes heavier and his shoulders slump when he admits that he didn't want Robin to turn out like him.
  • Parental Substitute: He is very much this to Dick Grayson. Dick actually gets jealous in one episode when Bruce privately lectures Aqualad after a disastrous mission. Bruce then alleviates Dick's concerns by playing basketball with him (claiming that it's "training").
  • Reasonable Authority Figure: He consistently appears hard and authoritarian, but fair and judicial.
  • Role Reprisal: From Batman: Under the Red Hood.
  • Secret Keeper: Knew Captain Marvel was a ten-year-old kid and that Artemis was the daughter of Huntress and Sportsmaster.
  • Stealth Hi/Bye: Is able to pull this of in the middle of a fight!
  • Uncle Pennybags: Besides being Dick's and Tim's legal guardian, he also provides for Superboy's expenses and gives Artemis an expensive scholarship to a private school.

    Wonder Woman 
Wonder Woman (Princess Diana of Themyscira)

Species: Amazon

When all is said and done, the question must be - whom do we trust?
Voiced by Maggie Q

Wonder Woman seems to stand as the moral center of the League. She takes a backseat in the story for the majority of the time, but is quick to call Superman and Batman out on their mistakes, and takes on Wonder Girl as her protege between seasons 1 and 2.
  • Everything's Better with Princesses: Wonder Woman is an Amazonian princess and a superheroine.
  • Flying Brick: Has superhuman strength and can fly.
  • Friend to All Children: Implied. She didn't agree with Batman's choice of letting Robin I enter the world of crimefighting at the age of nine; earlier, Wonder Woman didn't like the idea of Captain Marvel being in the League when he is only ten and was quite upset he (along with Batman) withheld the information.
  • The Heart: Acts as the moral center of the League.
  • Older Than She Looks: Her official stats say she's ninety-years-old (of course, she is partially immortal; physically she's roughly in her 30s).
  • Primary-Color Champion: As per tradition, she still wears a strapless red bustier held up by a brace of gold resembling two W's, a large golden belt, blue briefs with five white stars on them, red boots with a white stripe on the front side, silver bracelets around her wrists, red star earrings, and a golden diadem with a red star on her forehead.
  • Rapunzel Hair: Reaches down her waist.
  • Raven Hair, Ivory Skin: Long, raven hair and has a pale complexion.
  • Super Strength: Enough to rival Superman.
  • Warrior Princess: She's the daughter of Hippolyta, Queen of the Amazons, and she kicks ass. Drawing from her Amazonian training, Wonder Woman is quite adept in close-range battle. Using her bracelets, she is able to skillfully deflect incoming projectiles.

    The Flash 
The Flash (Barry Allen)

Species: Metahuman
Voiced by George Eads (Season 1, "Bloodlines"), James Arnold Taylor ("Endgame")

Mentor to Kid Flash, the Flash has taken up his mantel from its previous owner, Garrick. He's a dedicated uncle and mentor, and one of the more friendly League members, though still serious when needed.
  • Ascended Fanboy: In the tie-in comics, Wally explains that Barry was a big fan of The Flash and spent a lot of time talking to Jay Garrick before duplicating the Freak Lab Accident that gave him his powers.
  • Big Eater: Pretty much a given because he has to eat to regain his super speed.
  • Catch-Phrase: "Back in a flash!" Lampshaded by the Flash Family.
    Impulse: "Does he say that often?"
    Rest of the Family: *sigh* "Too often."
  • Cool Uncle: He's a little dorky, but Wally thinks he's cool.
  • Hair of Gold, Heart of Gold: A Nice Guy who's also a super hero.
  • Happily Married: To Wally West's aunt Iris.
  • Heroes Want Redheads: Married to Iris, who has the same red hair color as Wally.
  • Hot Scientist: When The Flash becomes Barry Allen, he's a CSI for the police; Barry has a degree in forensic science.
  • In-Series Nickname: "Bartholomew" is his full name, but he's nicknamed "Barry".
  • Interspecies Romance: Him (a metahuman) and Iris (a human).
  • Legacy Character: As seen in "Downtime", the Flash family has had several generations of speedsters.
  • Longing Look: To Iris in "Failsafe," but subtle since they're on air at the time and aliens are killing everyone.
  • Mundane Utility: In "Downtime", he uses his super speed to clear the dinner table inside of ten seconds.
  • Nice Guy: Which Mary West has been heard to hope will rub off on Wally.
  • Not His Sled: In the finale he recreates his famous death scene with his two proteges. Except in a twist he doesn't die — Wally does. It even looked like he was going to give his life to save Wally's, but when Barry got to him, Wally was already beyond saving.
  • Oh, Crap!: A much more tragic and heartbreaking one, but the look on his face when it's clear that he can't save Wally in Endgame is all over this
  • Red Is Heroic: Like always The Flash is a hero and sports his signature red suit.
  • Science Hero: He gained his powers by carefully recreating Jay Garrick's accident in a controlled experiment, and is a police scientist in his day job.
    Kid Flash: "Are you having a CSI moment?"
    Flash: "Kid, I was CSI before anybody knew what CSI was."
  • Super Senses: Flash can also speak, hear, and see faster than any normal being.
  • Super Speed: He's the Flash. Fastest man alive and all that.

    Green Lantern (Hal Jordan) 
Green Lantern (Hal Jordan)

Species: Human

Voiced by Dee Bradley Baker ("Agendas")

Aquaman (King Orin of Atlantis/Arthur Curry)

Species: Atlantean
Voiced by Phil LaMarr

King of Atlantis, mentor to Aqualad, and later Lagoon Boy.
  • Action Dad: He will be in nine months.
  • Badass Beard: Much like another Aquaman, he maintains his classic look whilst having the beard the character was first seen with during the 90's.
  • Chew Toy: He thinks Aqualad has betrayed him, Aquagirl is dead, and Lagoon Boy has been captured by Aqualad and Black Manta.
    • Is faring a bit better after "Before the Dawn" now that Lagoon Boy has been rescued but now Aqualad is catatonic as a result.
  • Does Not Like Shoes: Seems to be an Atlantean thing; webbed feet do make swimming easier, though.
  • The Good King: Of Atlantis.
  • Hair of Gold, Heart of Gold: A wise and reasonable adult, who happens to be a hero.
  • Happily Married: He has a close and loving relationship with Queen Mera.
  • Heroes Want Redheads: Is married to Mera, and expecting their first child.

    Martian Manhunter 
Martian Manhunter (J'onn J'onzz/John Jones)

Species: Martian

Trauma tends to linger - as I know you know, my friend.

The uncle of Miss Martian, this green skinned alien is a serious and reserved figure, though still a kind one. He clearly cares deeply for his niece, and it a formidable super-hero.
  • Last of His Kind: Surprisingly averted, given the character's other modern incarnations. His family alone includes hundreds of nieces and nephews. note 

    Green Arrow 
Green Arrow (Oliver Queen)

Species: Human
Voiced by Alan Tudyk

The supposed "Uncle" of Artemis, Green Arrow is a friendly face, politician and capable fighter. He suffered a falling-out with his first side-kick, Speedy (who took on the mantel Red Arrow) though he still cares deeply for him and tried to bring him back to the straight and narrow. Took Artemis on as his new protege to teach her his skills and give her an outlet for her super-heroing, per Batman's request. In a relationship with Black Canary.
  • Actually Pretty Funny: When Batman and Martian Manhunter show him and Black Canary a recording of Canary and Superboy kissing after a sparring match he is initially angry, until they see the rest and it turns out it was Miss Martian, who shapeshifted into Black Canary. Then he immediately starts laughing at the whole thing, much to Canary’s anger.
  • Badass Beard: Much like many incarnations, he's sporting the beard the character had after Neal Adams gave him one.
  • Badass Normal: He's got no powers, he's just a really good shot with a bow.
  • Blatant Lies: Claiming Artemis is his niece, which Red Arrow knew immediately was a lie.
  • Butt-Monkey: He has it worse than Aquaman. He thinks Artemis is dead, Red Arrow Rage Quit, and the original Speedy (Now Arsenal) was pissed off that he stopped looking and went to try and assassinate Luthor.
  • Cool Uncle: To Artemis though it's an obvious lie. After Roy marries Cheshire, Green Arrow technically becomes this to Artemis.
  • Doom Magnet: Starts to see himself as this in "Satisfaction".

    Hawkman & Hawkwoman 
Hawkman (Katar Hol) & Hawkwoman (Shayera Thal)

Species: Thanagarian

Zatara (Giovanni Zatara)

Species: Human

She's grounded for life!
Voiced by Nolan North

Zatara appears to be one of the older Leaguers— while Martian Manhunter and Wonder Woman have the years, they age differently. Zatara took a turn as the team's Den Mother after Captain Marvel and later brought his daughter, Zatanna, to meet them.

    Captain Atom 
Captain Atom (Nathaniel Adams)

Species: Metahuman

Voiced by Michael T. Weiss

A time-displaced veteran of the Vietnam War, Captain Atom was brought in to teach the team espionage and covert ops techniques. By season two, he's taken over as the Justice League's current leader.

  • All There in the Manual: If you thought his cameo in Homefront was out of left field, the tie-in comics explain that he was the team's instructor in covert ops. For practical experience, they cleared his name after he was accused of war crimes during the Vietnam War, which allowed him to reestablish contact with his estranged wife and adult children, so he knows the team, is grateful to them, and would be just as concerned as their other mentors when they realized something was wrong at Mount Justice. The tie-in comics also establish that Captain Atom was one of the first superheroes Jaime met, probably suggested him for recruitment, and Jaime respected him enough that he wanted to consult him before joining the team.
  • Adaptational Name Change: In the original comics, his name is Nathaniel Adam, with no 's' on the end, to drive home his Punny Name that much more. Weisman (who, as noted below, helped relaunch the character in the '80s) commented that it sounded unnatural to him even then and took the opportunity to adjust it.
  • Big Good: He's League Chairman in Season 2. He's a lot more hands-off than Batman, mostly because the Team has more than proven themselves by this point.
  • Clear My Name: In the tie-in comic he sends the Team to do that. He doesn't tell them whose name they're clearing, though.
  • Creator's Pet: Conscious effort to avert this: Co-Producer Greg Weisman co-wrote Captain Atom for DC Comics in the 1980s, including the story line that issues 10-11 of the tie-in comic are based on. He gave the original comics to YJ staff writer Kevin Hopps and asked him what should be cut, as he was too close to it to judge. Weisman also notes that it wasn't his idea for Captain Atom to be the League Chairman in season 2. He suggested Black Canary (who is his favorite character), but Co-Producer Brandon Vietti thought Captain Atom's military vibe would work well for the season.
  • Energy Absorption: One of his powers— he's seen absorbing the energy of a power plant about to go nuclear in Revelations.
  • Military Superhero: More apparent in the tie-in comic, but also informs his leadership style in season two.
  • The Leader: As League Chairman.
  • Older Than He Looks: He's actually 70 years old but, other than the white hair, doesn't look a day over 40.
  • Screw This, I'm Outta Here!: Upon G. Gordon Godrey's speculation that Lex Luthor would be the next Secretary General of the United Nations, Cap formally resigned his Chairmanship of the League.

    Black Canary 
Black Canary (Dinah Lance)

Species: Metahuman

A powerful hand-to-hand fighter aided with her "sonic scream", Black Canary is one of the main mentors to the team. Although her role was initially to train them in fighting and make sure they didn't get into trouble, she stepped into a more emotionally supportive role, even offering them therapy sessions when necessary. In a relationship with Green Arrow.
  • Hair of Gold, Heart of Gold: Despite her demeanor, she's an easy person to talk to.
  • Hot Teacher: She has Wally drooling over her, and though Superboy isn't exactly the most emotive of the cast, he clearly has a crush on her.
  • Interspecies Romance: Her (a metahuman) and Green Arrow (a human).
  • Legacy Character: Is the daughter of the original Black Canary according to Word of God.
  • Make Me Wanna Shout: When she actually uses her powers, which is rare.
  • Meaningful Name: "Dinah" is Hebrew for "judged", like how she judged (not harshly), but truly the psyches of the members of the Team. See Warrior Therapist.
  • Official Couple: With Green Arrow.
  • Resigned to the Call: Her reaction to becoming League Chairman.
  • Sexy Mentor: To Superboy, leading to M'Gann taking her form in a little shapeshifter makeout game with him. Dinah herself is not pleased.
  • Stern Teacher: To the Team, but gives praise when it is deserved.
  • Taught by Experience: Firmly believes that injuries and setbacks in missions is "part of the heroes job" and helps mature the hero.
  • Warrior Therapist: As shown in "Disordered". Not only does she train them, she helps them deal with trauma.
  • You Are Not Alone: Invoked. Black Canary tries to tell Clone!Roy that even though he feels lost, that doesn't means he's alone. Sadly, it doesn't sink in to him.

    Green Lantern (John Stewart) 
Green Lantern (John Stewart)

Species: Human

  • Badass Baritone: Courtesy of being a superhero that's voiced by Mr. Kevin Michael Richardson.
  • Dark Is Not Evil: His costume is mostly black, except for green parts on his wrists and on his shoulders and upper chest.
  • Heroic Build: John has quite a huge, slender build.
  • Imagination-Based Superpower Being a Green Lantern, his ring can create anything he can think of.
  • Space Police: The entire point of Green Lanterns to begin with.

    Captain Marvel 
Captain Marvel (Billy Batson)

Species: Human
Captain Marvel voiced by Rob Lowe ("Alpha Male" & "Humanity"), Chad Lowe ("Secrets" and after)
Billy Batson voiced by Robert Ochoa (Season 1), Chad Lowe (Season 2)

Though on the surface just a brave and chivalrous super-hero, Captain Marvel is actually just a good-hearted young boy in a powered adult's body. A little boy who just really, really wants the Team and Justice League to like him. Don't let his puppy-dog demeanor fool you, though. His good nature earned his powerful abilities, and when he's not fooling around, he's pretty wise, too.
  • Adorkable: He tries so hard to fit in.
  • Attention Deficit... Ooh, Shiny!: Being a young boy on the inside, Billy can be easily distracted by something cool. Like tigers.
  • Ascended Fanboy: Billy idolizes all heroes and is a hero himself who works with said heroes he looks up to.
  • The Baby of the Bunch: Deconstructed. After his real age was found out, a few of the Leaguers wondered if Captain Marvel should be on the team because of it. And that while he may have the Wisdom of Solomon, that doesn't mean he's mature.
  • Brainy Brunette: He has black hair and the Wisdom of Solomon.
  • Butt-Monkey: He constantly tries to get close to the team, who are essentially his peers. The team tends to assume that he's as authoritarian and hard-nosed as the other members of the League, so they (often unintentionally) undermine, take advantage of, or otherwise reject him in the process of saving the day. It's probably not the case after Billy revealed who he really was to them in "Misplaced".
  • Calling Your Attacks: He would sometimes announce or reference which of his powers he was using at a time, whether it was using the Power of Zeus and Speed of Mercury to drill into the ground, or cite the Wisdom of Solomon as the source of his good advice.
  • Flying Brick: His comic counterpart was one of the first flying bricks in comics, so it carries over here.
  • Henshin Hero: Transforms from the powerless Billy to superpowered Captain Marvel.
  • Heroic Build: He has a big build and besides being a hero, he's one of the nicest.
  • Honorary True Companion: Honorary because he won't join the Team; he's part of the Justice League. During Invasion, the League usually paired with former team members Rocket and Zatanna, and he was with Zatanna helping the group who lived at Mount Justice move.
  • Innocent Blue Eyes
  • I'm Standing Right Here: After his secret's revealed to the League at large, they have to debate whether he can stay.
    Red Tornado: He does possess an adult body and the wisdom of Solomon.
    Aquaman: Wisdom does not equal maturity.
    Marvel: Hey, I'm sitting right here!
  • Just a Kid: He gets this treatment from some of the League in "Agendas" after real age was revealed.
  • Manchild: As with the comic example, Captain Marvel is really a kid. However, none of the teens know his real form, so he definitely comes off as being this trope.
  • Nephewism: In this version, Billy is being properly cared for by his Uncle Dudley.
  • Nice Guy: The nicest.
  • One of the Kids: Captain Marvel is known for retaining his innocence, but this incarnation is especially childish.
  • Papa Wolf: In order to protect the team from Despero. Considering his true age, maybe its more of a Big Brother Instinct.
  • Primary-Color Champion: His costume is mostly red with gold accents like his thunder bolt logo, sash, and boots. He also wears a white cape.
  • Secret Keeper: Billy has to keep the identity of Captain Marvel a secret due to the fact that he's really a ten-year-old kid. As of "Misplaced", the Team knows about his true identity. It's also clear that Batman knows but other Leaguers like Zatara don't, though they find out after this.
  • Shock and Awe: An unorthodox version: he gets struck by lightning every time he transforms from Billy to Captain Marvel or vice versa, and he's not above weaponizing it when the situation calls for it.
  • Sixth Ranger: How he views himself in regards to the team. Unfortunately for him, the team didn't know that he's a kid until he revealed himself in "Misplaced", so they did what they can to keep him out of the loop.
  • Something Only They Would Say: Billy goes back to the world of kids in Misplaced and asks Miss Martian to read his mind to prove that he's really Captain Marvel. Kid Flash doesn't buy it. Then, Billy goes:
    Billy: Gee Wally, do I really have to bring you nachos and pineapple juice to get on your good side?
  • Super Strength: He's as strong as Superman.
  • Tagalong Kid: Despite never being a kid at the time.
  • What the Hell, Hero?: In "Agendas", he's the first Leaguer to call out Nabu for the events of "Misplaced". He doesn't know why they're even keeping him in the League.
    • Shortly after, however, the rest of the League, particularly Wonder Woman, call him out for concealing his age.
  • Wise Beyond Their Years: Lampshaded by Captain Marvel himself (the "wise" part anyway), when Aqualad thanks him for a pep talk.
    Marvel: Hey, wisdom of Solomon.
    • Seems to be in an "Only when I feel like it" way, since whenever nothing serious is going down, he's just a big kid.
    • As pointed out by Aquaman when the League finds out about his alter-ego, "wisdom" doesn't necessarily mean "mature".
  • You Didn't Ask: The reason why he hid his age from the Justice League.
  • Younger Than They Look: As Captain Marvel. Billy looks his young age.

    Red Tornado 
Red Tornado (John Smith)

Species: Robot

Human customs still elude me.
Voiced by Jeff Bennett

A robot with wind powers, Red Tornado doesn't quite get human emotions. That doesn't stop him for caring deeply for the Team he's been assigned to protect, (in his own way).
  • Blow You Away: He has the power to generate wind.
  • Color Character: Red Tornado.
  • Demoted to Extra: He's conspicuously absent in the second season (likely because Nightwing and the others have replaced him in the mentor role), and has only had one non-speaking appearance in "War".
  • Face–Heel Turn: Subverted. It seems as if he defects in "Homefront", but in reality, he leaves to protect the Team and to find his creator, T.O. Morrow.
  • Helping Would Be Killstealing: Every time the team ask for help he tells them they have to do it on their own.
  • Heroic Sacrifice: Was trying to make one with his siblings when he nearly melted to take down his evil brother. Superboy saved him at the last minute.
  • Took a Level in Kindness: He became the Den Mother in order to become more human. It has had an effect, as he's come to care for the Team... and later on, his "father."

    Doctor Fate 

Species: Lord of Order
Fate has intervened.

An ancient being tasked with protecting the world from the powers of chaos, Dr. Fate must take on a mortal body as his host- and he doesn't much care what said host has to say about it. While he can be a major asset to the forces of good, the price paid might sometimes be too high.
  • And I Must Scream: Fate's host is trapped inside their own head, able to observe how Nabu controls them but are unable to do anything about it. Nabu himself is trapped in the helmet and part of his lack of concern over possessing his host is because he's sick of being nothing more than an ornament.
  • Attack Reflector: In "War", he is able to absorb the beam from the WarWorld's Wave Motion Gun and send it right back, utterly wrecking the gun.
  • Badass Baritone: A deep voice courtesy of Mr. Richardson.
  • Badass Boast: In Revelation, he gives a nice one as he disperses the Joker Venom.
    Fear not! Fate has intervened!
  • Badass Cape: Whoever wears the Helmet of Fate get a badass golden one.
  • Body Snatcher: How many regard him, especially Captain Marvel.
  • Brutal Honesty: He tends not to bother with beating around the bush, most of the time.
  • Clingy Costume: Once someone puts on the Helmet of Fate, it cannot be removed unless Nabu wants it to.
  • Combat Stilettos: When possessing Zatanna.
  • Converse with the Unconscious: Regularly converses with whoever is serving as his host, even though he's fully inhabiting their body.
  • Cool Helmet: Essentially IS the helmet.
  • Deadpan Snarker: Very occasionally.
  • Forbidden Chekhov's Gun: The helmet is mentioned during a crisis and the League considers if they're desperate enough to use it - mainly because Nabu doesn't particularly like the idea of relinquishing his host. Every time someone puts the helmet on it's because the situation has crossed the Godzilla Threshold.
  • Good Is Not Nice: He's never claimed to be nice. Or even specifically good, for that matter.
  • The Hat Makes the Man: Possesses the body of whoever puts on the Helmet.
  • Haunted Fetter: The Helmet is possessed by Nabu, who in turn possesses whoever puts it on.
  • Killed Off for Real: Kent Nelson. His spirit did reside in the Helmet of Fate for a while, but Fate eventually got tired of his nagging every time someone used the helmet and sent him off to the afterlife.
  • Large Ham: He's not too emotive, but nearly everything Nabu says has a tremendous amount of gravitas.
    Fate: Wotan! You are mine!
  • Legacy Character: Several people have wore the Helmet of Fate, but most of them temporarily.
  • Light Is Not Good: A borderline example. Calling him good is generous, all things considered, yet, his golden light powers and ankh symbol definitely render him light aligned.
  • Mask of Power: The Helmet of Fate turns the wearer into a host for an extremely powerful Lord of Order, who's got some crazy powerful magic abilities.
  • Morally Ambiguous Doctorate: He's called Doctor Fate, but whether he is a doctor is unspecified. He's also not particularly nice.
  • Not So Stoic: Sometimes, since it's indicated that his personality is at least somewhat influenced by whoever is serving as host at the time.
    • When being hosted by Zatara and Zatanna is considered for League membership, he breaks his usual emotionless attitude.
  • Order Versus Chaos: Represents order, and not necessarily in a very nice (or classically good) way.
  • Pet the Dog: He listens to Kent Nelson, who's just about the only person who can persuade him to do anything until Nabu eventually gets bored of his nagging and releases him to the afterlife.
    • He also accepts Zatara's promise to become the new host of Fate and willingly releases Zatanna, even though he'd have no control over whether or not Zatara actually followed through.
  • Power Makes Your Voice Deep: Wearing the Helmet of Fate will make the wearer speak with Nabu's deep voice overlaying their voice.
  • Powers That Be: Is a personification of order given form on the physical plane.
  • Powers via Possession: How Fate works - though it is indicated that it helps if the host is already magically gifted.
  • Suspiciously Specific Denial: When discussing whether or not to release Wally as his host, Nabu first mentions how lonely and depressing his existence as a helmet on shelf is before loudly asserting that he just wants to stop the forces of Chaos. Seeing as Kent agrees to hang around and keep Nabu company, it wasn't a very convincing claim.
  • Token Evil Teammate: While more morally ambiguous than outright evil, compared to the rest of the League, he's very dark.
  • Took a Level in Jerkass: Implied by the fact that Kent, his original host, had a full life outside of being Doctor Fate, suggesting that Nabu used to be more relaxed about being put on and taken off. Several decades on a shelf seem to have somewhat soured his disposition and made him very disinclined to release his host.
  • Took a Level in Kindness: ... but his disposition improves somewhat after getting a permanent host.
  • Unscrupulous Hero: His actions are motivated purely by a desire to maintain order rather than any moral compulsion and he has few qualms about suppressing the identity of (and effectively killing) anyone he possesses, even if they're children - though he was convinced to release both Kid Flash and Aqualad without anyone else sacrificing themselves, and he is at least aware that putting on the helmet is a sacrifice. For example, when he possesses Zatanna:
    "Fate decrees her sacrifice will not be in vain!"
  • Voice of the Legion: A (largely) heroic example. Whoever wears the Helmet of Fate will speak with Nabu's deep voice overlying their voice.
  • Well-Intentioned Extremist: He is absolutely convinced that the world needs him (and not without reason), and if that means whatever mortal happens to be wearing the helmet never gets to take it off, so be it. It's reached the point that Captain Marvel doesn't understand why they're letting him stay in the League, and is justifiably sceptical when Nabu claims that Zatara wants him to remain part of the League. Nabu then explains that Zatara wants him there so they can keep an eye on him.
  • Willing Channeler: Someone has to choose to put him on, though they might come to regret it.

    The Atom 
The Atom (Ray Palmer)

Species: Human
Voiced by Jason Marsden

Mentor to young heroine and his lab assistant, Bumblebee.

    Plastic Man 

Species: Metahuman
Voiced by: N/A

Plastic Man is a superhero and member of the Justice League.
  • Fun Personified: He's nearly always smiling, and according to Captain Marvel, stages practical jokes every April Fool's Day. At one point, the mere mention of his name sends Cap into uncontrollable laughter.
  • Perpetual Smiler: Every appearance he's seen in, he's always smiling.
  • Rubber Man: Plastic Man has the ability to stretch his body, and assume the shape of other objects.

Icon (Augustus Freeman)

Species: Unspecified alien
We both seem to have found teams that suit us.
Voiced by Tony Todd

Icon is a superhero of extraterrestrial origin, partner and mentor to Rocket, and a member of the Justice League.

    Red Arrow 

    Blue Beetle II 
Blue Beetle II (Ted Kord)

Species: Human

The second Blue Beetle. His death in a lab explosion indirectly led to Jaime finding the Scarab and becoming his successor.
  • Badass Bookworm: Kord was a brilliant inventor.
  • Badass Normal: He never used the Scarab himself, just based his hero persona on it.
  • Blue Is Heroic: True to his name, Blue Beetle wore blue. His pants and shirt were of a light blue color, with darker blue trunks. The top section of his shirt was adorned with a dark blue cutout that resembled bug's legs. He wore dark blue gloves and boots, and a belt with a golden buckle. To hide his face, he wore a dark blue cowl with yellow goggles.
  • Color Character: Blue Beetle.
  • Dying Moment of Awesome: Going head to head against both Deathstroke and Sportsmaster at the same time in order to keep the Light from getting the Scarab forever cements him as an incredible badass. Taking into account the fact that Jaime ended up getting it, this also means that the explosion which claimed his life probably wasn't deliberate on the part of the villains.
  • Gadgeteer Genius: Batgirl's dialogue in "Intervention" and everyone's initial belief that the Scarab was something he created implies that he was this.
  • Legacy Character: The second Blue Beetle.
  • Nice Guy: He was considered a good man.
  • Posthumous Character: He died during the Time Skip between seasons 1 and 2, making him this in relation to season 2 (he would have been alive during season 1, but he never appeared).
  • Sonic Stunner: Apparently his weapon of choice, no doubt inspired by the Scarab armor's version.

    Black Lightning 

    Green Lantern (Guy Gardner) 
Green Lantern (Guy Gardner)

Species: Human

Earth's third Green Lantern. When the League considers an expansion in "Agendas", the Flash puts his name forward - something Hal and John are both very opposed to.
  • Alliterative Name: Guy Gardner.
  • Big Damn Heroes: Saves a falling bus of children when Green Arrow, Red Arrow, and Black Canary all fail to stop it from falling.
  • Fingerless Gloves: He wears black fingerless gloves.
  • Imagination-Based Superpower: Being a Green Lantern, his ring can create anything he can think of.
  • Jerk with a Heart of Gold: Implied. Judging by Hal’s and John’s "No. Just... No" Reaction at the idea of letting Guy join the League and Cassie’s own exclamation that he doesn’t like anyone one could reasonably say that he’s a bit difficult in terms of personality. However, Guy is a hero first, as seen when he saves a bus full of innocents. Nightwing also says that Guy is actually fond of Jaime Reyes in his own way (Which is quite possibly a Shout-Out to the fact Guy was rather fond of Jaime in the comics as well), which is a telling thing for Cassie.
  • "No. Just... No" Reaction: How Hal and John react to the proposal of adding Guy to the League, though they eventually add him to the League anyway.
  • Significant Green-Eyed Redhead: Guy has short red hair and green eyes.
  • Sleeves Are for Wimps: He wears black pants and a black sleeveless shirt with a green front.
