Characters: Legion of Super-Heroes aka: The Legion Of Super Heroes
Useful Notes on Legion Continuity:The Legion of Super-Heroes has been ongoing in one form or another since 1958, encompassing three completely distinct continuities and several more "branch" continuities. That being the case, there are many alternate versions and a lot of Character Development involved, and what tropes apply to what characters varies from version to version. Here's a thumbnail reference for what refers to what part of continuity:
Preboot—The original continuity, prior to the 1994 Zero Hour continuity reboot. These stories take place on Earth-1 (Pre-Crisis) or Earth-0 (current continuity).
V4 / 5YL / TMK—"Five Years Later", the fourth volume of the Preboot title, a Darker and Edgier continuation following (as the title suggests) a five-year Time Skip. The 5YL stories were mostly written by Tom and Mary Bierbaum and drawn by Keith Giffen, usually abbreviated to "TMK".
Softboot / Glorithverse—The state of Legion continuity after a Cosmic Retcon unleashed during V4 to write the Pocket Universe Superboy out of continuity. Glorith was a time-controlling villainess who took advantage of the retcon.
Batch SW6—One of the most significant ongoing storylines from 5YL, involving a group of time-paradox duplicates of the early Legion (who went on to star in the Spin-OffLegionnaires until Zero Hour). The term comes from the cryptic labels of the People Jars the duplicates were found in. note Well, that was the reason in-story. It actually came from half of a fan's postal code.
Retroboot / Deboot / Johnsboot—The version of the original continuity Legion that appeared starting in 2007's "The Lightning Saga", branching off from the Preboot continuity just before 5YL, except that Superboy didn't die.note Superboy had to die because changes to Superman's history post-Crisis erased Superboy from history. A "Pocket Universe" Superboy was introduced and killed to patch the plot holes. Superman's history was (partly) changed back, so this is no longer necessary. So named because its tone was set by writer Geoff Johns.
Postboot—The continuity following the 1994 Zero Hour reboot, up until it was rebooted again in 2004. These stories take place on Earth-247.
Archie Legion—The relatively lighter initial portion of the Postboot.
DnA—The Darker and Edgier "Legion of the Damned" and "Legion Lost" stories by Dan Abnett and Andy Lanning.
Threeboot—The continuity following the 2004 reboot, re-envisioning the Legion as a rebellious youth movement in a stagnant society. These stories take place on Earth-Prime.
L3W—Legion of Three Worlds, a Final Crisis limited series bringing together the Retroboot, Postboot, and Threeboot Legions.
The version of the Legion currently appearing in comics is the "Retroboot" based on the original "Preboot" continuity, described above.Characters below are listed in the era in which they were introduced, not when they joined the Legion. For instance, Night Girl was introduced in the 1960s but didn't become a full member until 2007, while Kid Quantum was introduced in 1990 but Retconned into being a member during the Silver Age era.The Animated Adaptation has its own main page and character sheet.
open/close all folders
AKA: Rokk Krinn
Abilities: Magnetism manipulation
In most incarnations, the leader of the Legion. Cosmic Boy's serious demeanor and respect for authority lends him to the role of leadership, but places him at odds with Lightning Lad. Preboot, his brother was Pol Krinn, aka Magnetism Lad. His personality, like his power, is magnetic—he draws people to his cause with his charisma.In the FYL continuity, Cosmic Boy was De Powered during a war between Braal and Imsk. He married Night Girl and had a son named Pol after his late brother. Shortly before his reality was destroyed by Zero Hour, he regained his powers thanks to a pair of power gauntlets and took the name Polestar.Postboot, Cosmic Boy was a sports star whose talent helped him as a superhero. When half the team was stranded in the present day, Cos led them through Final Night and Genesis and was instrumental in getting them home. When the Postboot Legion's Earth was destroyed in Infinite Crisis, he continued to lead them, and in their current exile as the Wanderers, he is leading them in their search for a new home.In Threeboot, though Cosmic Boy founded the Legion, he was widely disliked because he was forced to accept supervision from the United Planets. He struggled with command, and after the Dominator War, ceded leadership to Supergirl. He was approached by a group of superheroes from the 41st century whose legacy he inspired and joined them in the future.
Stripperific: His costumes in the Grell era. Admittedly, so were most of the other characters' costumes at the time, but Cosmic Boy's Rocky Horror-esque corset and Saturn Girl's bikini (see below) are the best-remembered.
A telepath from one of Saturn's moons, Saturn Girl is the glue that holds the Legion together, keeping a balance between the cool-headed Cosmic Boy and Hot-Blooded Lightning Lad. When Cos isn't the Legion's leader, it's usually her. In all incarnations of the Legion, the love of her life is Lightning Lad.In Threeboot, Saturn Girl's people were so reliant on telepathy that their vocal cords were useless. She was distant and reserved. Her mother was a member of the United Planets council, which put her at odds with the more iconoclastic Legionnaires.
I Let Gwen Stacy Die: An odd precursor subversion. Silver Age Imra refused to stop looking for a way to bring Lightning Lad back from the dead after he performed his Heroic Sacrifice because he died saving her, even though she had been trying to perform said sacrifice so her teammates wouldn't have to.
Mama Bear: Preboot/Retroboot. This woman went up against Darkseid to restore one of her sons to normal. Unless you want to end up as a mindless heap on the floor, do not mess with her kids.
Mind Over Manners: Generally observed, although Postboot!Saturn Girl has had a few memorable, if accidental lapses. Like telepathically animating a comatose Cosmic Boy to help keep the Legionnaires trapped in the past together—and turning him into her Relationship Stu. Then in Legion Lost, Imra used her psychic powers to make Ultra Boy think that his wife, Apparition, was with them in their deep-space exile, and when he found out, he was pissed.
Official Couple: With Lightning Lad. Various attempts at shaking it up have proven futile and/or unpopular.
Pink Girl, Blue Boy: The pink girl to Lightning Lad's blue boy. However, she's also been known to wear red instead of pink.
Well-Intentioned Extremist: Preboot, during a Silver Age story where she rigged an election for leader, secretly stole her teammates abilities, and then had them suspended for arbitrary reasons. It turned out she did all that in order to spare her teammates from fighting in an upcoming battle with an alien overlord, where a member would've surely been killed. Her plan failed when Lightning Lad discovered what she was planning, and sacrificed himself in battle.
Your Cheating Heart: Cheats on Lightning Lad with Ultra Boy in the Threeboot continuity because she feels "neglected". It ends badly for everybody involved.
Lightning Lad/Live Wire
AKA: Garth Ranzz
Abilities: Electrical generation and direction
Artificial Limbs: Loses an arm in most continuities, though what it's from varies wildly.
The Chosen One: Preboot Garth was secretly revealed to be an individual whose life has been keeping a balance between science and magic, and that the actual Luck Lords of Ventura had been planning to manipulate his death during a cosmic convergence so as to bring about the return of magic and luck with science's death. None of the Legionnaires or Garth himself ever found this out.
House Husband: The Preboot version, while his wife went back to being a Legionnaire, Garth was the one willing to stay at home and look after their twin sons, Graym and Garridan.
Informed Flaw: His so-called legendary bad luck. However, a spotlight issue revealed that Garth's luck is exceedingly good, and has been preventing the Luck Lords from bringing about the death of science in the universe. He received lightning powers, came back from the dead, got a robot arm and later had his flesh arm regrown, married the love of his life and had her children, and they are all happy and healthy. Does that sound like the unluckiest Legionnaire?
Hidden Heart of Gold: The SW6 version is arguably the meanest of all the alternate Lightning Lads, at one point punching Cosmic Boy in the face because he thought he was coming on to Saturn Girl. A Lotus-Eater Machine experience revealed, however, when he was young he accidentally killed his pet and felt insanely guilty about it. His parents saying they could easily replace it and tossed it away didn't make him feel better. Live Wire's ruder tendencies seemed to have been amped up whenever he was around Inferno, who was an even bigger jerkass in comparison.
The Lancer to Cosmic Boy's Hero, when Saturn Girl isn't filling the role instead.
Made of Iron: The Preboot version of Garth was once subjected to Mind Rape by the Time Trapper in an effort to learn the Legion's secrets, believing Garth to be the weakest of the Legion founders and easily susceptible to insanity. None of the Trapper's attempts at shattering Garth's will worked and the Trapper eventually ceded defeat.
Took a Level in Jerkass: His Johnsboot counterpart, which is supposed to be technically the original Lightning Lad, would often get angry as easily as some of his counterparts and sometimes had a tendency to throw temper tantrums when Saturn Girl wouldn't take his side. Fans were put off by this considering the original Lightning Lad actually subverted the Fiery Redhead trope most of the time and only really got mad on certain occasions. However, when taking into consideration that this version of Garth has been forced to go into hiding, has been separated from his children and his sister, and has basically watched everything he and his friends built and stood for destroyed overnight while simultaneously getting branded as terrorists, this becomes a more Justified Trope. Also of note, since Paul Levitz returned as Legion author, the Johnsboot Garth has calmed down considerably.
Big Beautiful Man: Artists have drawn him with a fair amount of muscle over the years, making him appear beefy instead of simply fat. And even without that, fans find him attractive and utterly adorable.
Big Eater: Subverted. Chuck is implied to have a big appetite but it's never really seen on panel, save for the incident where he drank the experimental formula that gave him his power. He didn't bother to look down at what bottle he was reaching for.
Demoted to Extra / Ascended Extra: Like Matter-Eater Lad, Chuck was deemed too silly for the Postboot Legion, so he was recast as a non-powered mechanic contracted to the Legion. However, he proved popular, so during the DnA era he was promoted to "Chief Engineer" and joined the main cast... with his rather unique spaceship, the Bouncing Boy.
Fun Personified: Pretty much his job for most of his career with the Legion. During the Preboot era, he was the Legion's self-appointed morale officer.
Happily Married: To Luornu, preboot and retroboot. They were the first Legionnaires to get married.
Heart Is an Awesome Power: Yeah, he seems silly, but think about it: he's pretty much physically invulnerable, can accelerate to outrageous speeds when he bounces, and then he slams into you in a massive attack from above. A 200 pound mass moving at 80 miles per hour generates an awful lot of kinetic force...
Lethal Joke Character: As pointed out elsewhere on the wiki, a 200+ pound weight that can fling itself around the room at remarkable speed is pretty dangerous.
Mr. Fixit: Postboot was too serious for Bouncing Boy, so it had Chuck Taine as the Legion's resident mechanic/engineer.
Brainiac 5/Brainiac 5.1
AKA: Querl Dox
Abilities: 12th level super intelligence; force-field projection (Postboot only)
Badass Bookworm: He's the Legion's brains, but he can also throw down when he has to, and is rarely a hindrance when things get physical. Given who some of his teammates and enemies are, this makes him a certified badass.
Barrier Warrior: Wears a belt that projects an impenetrable forcefield around himself; can sometimes extend the field to do more creative things with it.
Insufferable Genius: More often than not, depending on the writer. In the postboot continuity, he's so fed up with the other Legionnaires pestering him for help that when the Emerald Eye grants his heart's desire, he becomes invisible and inaudible to everyone but himself and simply goes about his own projects without interference.
This is most apparent in Legion of Three Worlds, where Retroboot, Postboot, and Threeboot Brainy all have to work together and just can't stop arguing.
May-December Romance: His Retroboot counterpart during New Krypton is still in love with Supergirl, even though, at that point in time in the 21st Century, she's still a teenager and he's an adult. Of course, Querl doesn't admit this to Kara because she had yet to actually join the Retroboot Legion.
Science-Related Memetic Disorder: Goes crazy with remarkable frequency. The apparently decorative wires on his face are, in postboot continuity, part of a mental limiter that keeps him from becoming so intelligent that he becomes hopelessly focused on matters of cosmic knowledge, useless and/or insane.
Wonderful Life: He's subjected hilariously to a Wonderful Life plot in a side story in one of the Postboot issues. When it appears that everyone else really would be better off without him, he decides he would rather go on existing just to make them miserable.
Year Inside, Hour Outside: His Glorithverse counterpart. During an Annual which acted as a recap of events in Legion history altered to fit the new continuity, Glorith kissed Brainiac 5 for a few seconds after he discovered that she'd been manipulating the Legion the whole time. Due to her time manipulating abilities she made the kiss last an eternity, effectively driving him insane in order to make him forget this revelation.
Magic Pants: In Threeboot, after his teammates get new uniforms, Cham decided to alter his costume's design. That's when it dawns on Star Boy that Cham's costume is a part of his body, meaning he's been walking around naked the entire time.
Older and Wiser: In the Five Years Later continuity, Cham becomes the mentor to the younger "Batch SW6" Legionnaires.
Which inspired one Elseworlds, "Superboy's Legion", to feature him doing just that - dying in the fledgling Legion's first encounter with the Fatal Five.
My Greatest Failure: In the Postboot, he was appointed the Legion's leader for one mission that ended in the death of Kid Quantum; he immediately abdicated in favor of Cosmic Boy and never forgave himself. (See Martyr Without a Cause, above.)
Fainting Seer: Postboot, she literally only gets visions in her dreams, but visions can strike at any time, resulting in narcolepsy- until she gets over it via Training from Hell which results in her no longer sleeping. Ever.
Took a Level in Badass: Postboot; see above. In original continuity and Threeboot she can use her shorter-range precognition to predict opponents' moves in battle, and even uses this to take out two Naltorian cops who've been trained in the same skill.
Martial Pacifist: Some continuities have him as a deeply religious man who only uses his transmutation powers in nonviolent ways- and it's easy to see why, once Leviathan suggests that he just "turn the Fatal Five into Cheez Whiz".
Odd Friendship: His Postboot version with Monstress. He was often seen complimenting her on her appearance and wardrobe without appearing to be hitting on her, but from the way they interacted with one another there appeared to be potential for a romantic relationship.
Continuity Nod: The Preboot Ferro Lad is best known for sacrificing his life to stop a Sun-Eater. The Postboot Ferro first appears during the Final Night crossover, featuring another Sun-Eater, and offers to give his life to stop it, but is quickly told, "That's OK, son, but you've got too much to live for," and Hal Jordan stops it instead.
Facial Horror: Why he always wears a mask. We never get to see it, but Postboot he looks for medical treatment and is told that notonly is his skull structure sprocked up beyond repair, but his muscle and skin tissue are mixed in with it at random. The only help possible would come from a metallurgist and require him to remain metal for the rest of his life, sacrificing most of his senses of smell, taste, and touch. He still considers it for a while before deciding to keep his fleshy form. Later, he was just starting to accept his appearance when he was wounded and Mode Locked into metal form- with the mask on.
Heroic Sacrifice: Preboot. Postboot, he had a twin brother who died protecting him and some of the timelost Legionnaires under unrelated circumstances.
What Could Have Been: Jim Shooter wanted to make Ferro Lad African-American, but the editors were worried that they'd lose distribution in the South. So Shooter decided to have him heroically sacrifice himself.
Sacrificial Lion: A variation where the character himself has been around for a long time, but his new role as a Legion member came just before his death—he was first revealed to be a member in Legion of Three Worlds, where he was killed. Previously he was only an honorary member, and he had only had the ring for a brief time.
Invisible Kid I
AKA: Lyle Norg
Amazon Chaser: Invisible Kid develops a crush on Gazelle after seeing her in action.
Gadgeteer Genius: In the Postboot continuity, Brainy was more the pure scientist, doing things like creating antigravitic material as a side effect of an experiment, and Lyle was more the engineer, doing things like taking said metal and producing flight rings from it.
Invisibility: Threeboot amps up the power by making him undetectable even by the most advanced tech.
Naïve Newcomer: Threeboot's first arc is told almost entirely through his perspective and is about how alien everything is to him.
Super Serum: The source of his powers. In the Threeboot, he gives the serum to the Science Police in exchange for them leaving the Legion alone- but not before somehow encoding it with a virus that gives the Legion a backdoor into SP computers after it's analyzed.
Teen Genius: Threeboot Brainy goes so far as to say that Lyle's plan involving the virus mentioned above was the cleverest thing a human had done since the discovery of fire.
Teen Superspy: Postboot, this was his pre-Legion job, and he goes on to found the Legion Espionage Squad with Triad, Apparition, Shrinking Violet, and Chameleon. He also leads the Squad in most continuities where it exists.
The Everyman: Threeboot has him as an obvious audience identification character.
Badass Normal: No version of Karate Kid has ever had an actual superpower. No version of Karate Kid except the one from the animated series has ever had any trouble with the Legion's traditional requirement that all members have an intrinsic superpower. The first version of the character accomplished this by proving he could stand up to no less than Superboy himself.
Charles Atlas Super Power: Karate Kid's martial arts skills have progressed to the point where they are a legitimate superpower, allowing him to split steel beams and destroy spaceships with his hands, even going so far as to give Superboy a tussle during his entrance exam. In fact, Karate Kid's skills are so advanced that when the United Planets outlaws the use of superpowers in one Preboot story, he is no longer allowed to use his karate or judo because they qualify as a superpower.
Fad Super: An unusual case because he is a preexisting character who became one for a while long after he was introduced. In the 1970's, he was suddenly modelled after Bruce Lee (and drawn Asian), given a robe instead of a superhero costume, and spun off into his own series which was sold as a martial arts series until the martial arts fad died out. Also, note that the movie The Karate Kid came out decades after his premiere - the credits actually mention that DC Comics owns the rights to the name. (Unfortunately, in-universe he debuted a thousand years later, which leads to silly jokes being made every time he meets someone from the 21st century.)
Race Lift: Started out Caucasian and has been Race Lifted back and forth to and from Asian a couple times.
Writer on Board: Keith Giffen really does not like Karate Kid, and has said up-front that any time he ends up writing the Legion he will kill off the character, as he did in 1984. (To Giffen's credit, he gave the the character an appropriately badass exit saving his wife's planet from the Legion of Super-Villains in a story arc that's remembered fondly by many fans.)
Lightning Lass/Light Lass/Gossamer/Spark
AKA: Ayla Ranzz
Abilities: Electrical generation and direction (as Lightning Lass/Spark); gravity manipulation (as Light Lass/Gossamer)
Bi the Way: Her Preboot and FYL counterparts were both heavily implied to be in relationships with Shrinking Violet. Following the Retroboot, it appeared that she had gotten back together with Timber Wolf, but her relationship with Violet appears to have been brought back in the recent Legion annual.
Adam Westing: A fictional version. By the time of the FYL Legion, Tenzil had gained a rock star persona and reveled in the ridiculousness of his power. He's a senator on Bismoll and a star of multiple TV shows, which he used to his advantage to get Polar Boy out of jail by having his trial televised and utterly owning the Dominator-controlled Earthgov.
Demoted to Extra: As with Bouncing Boy, Postboot was too down to earth for a guy with powers like his, so he became the Legion's cafeteria chef. Threeboot, he's a lawyer who searches for Cosmic Boy alongside the Legion- seeking to arrest him for war crimes.
Put on a Bus: After he ate a cosmic "Miracle Machine", M-E Lad went insane and was returned to his home planet. This was because the writers thought he was too silly and wanted to get rid of him without killing him.
Temporary Bulk Change: In a Preboot Silver Age issue involving the Legionnaires trapped in a prison camp for superheroes, M-E Lad was hit by a ray that slowed down his Bismollian metabolism to that of a normal human, thereby making it impossible for him to eat anything anymore. He had previously eaten about a ton of dirt in order to form an escape tunnel, so when his metabolism slowed down he swelled to the size of a balloon.
Abilities: Super-strength, speed, senses, flight, and invulnerability
Secret Identity: Postboot, Valor is a religious figure due to having seeded intelligent life on most of the worlds the Legion hails from, and when they manage to release him from the Phantom Zone, there's very nearly all sorts of riots over different races' beliefs regarding the legendary hero. They manage to get him out in secret, though, and eventually he takes the name M'onel as his new identity.
AKA: Lydda Jath
Abilities: Superhuman strength, activated in darkness
Ascended Fangirl: She was a member of the Legion of Substitute Heroes and idolized Cosmic Boy to the point of being a stalker. As the Superdickery of the Silver Age was quietly downplayed, she became Cosmic Boy's long-time girlfriend. She only became a Legion member recently after a long stint as a supporting character.
Rebellious Princess: In Postboot, she's the daughter of her planet's ambassador and earns her way into the Legion virtually as soon as they're announced to the world for helping to defeat a terrorist attack on the United Planets. Her mother's not pleased with either this or her romance with Ultra Boy.
Expy: Personality-wise in Postboot, She's basically Andromeda 2.0.
Proud Warrior Race Girl: Tasmia's origin lies somewhere between "native powers" and "unique powers", in that she is the "Shadow Champion" of Talok VIII. In some continuities, this means that all Talokians have these powers and she's officially the best at using them in combat; in others (Postboot particularly), she's officially the best in combat among Talokians, and that earns her the right to her powers. The latter scenario turns out disadvantageous in Postboot when she's missing and presumed dead by her people and they appoint a new champion.
Royals Who Actually Do Something: In some continuities, "Shadow Champion" is a hereditary position, making her akin to a princess or queen who is officially required to kick ass.
Ship Tease / What Could Have Been: Upon her introduction in Postboot, her narration briefly mentioned an attraction to M'Onel. They had been a long-standing couple in Preboot, but nothing came of it.
What Does She See in Him?: Her Retroboot counterpart has broken up with Mon-El and entered into a relationship with Token Evil Teammate Earth-Man. Tasmia tries to justify this in that he is a warrior befitting of her race, but her teammates aren't exactly buying it.
Shrinking Violet/Virus/Veye/LeViathan/Atom Girl
AKA: Salu Digby
Abilities: Able to shrink to microscopic size; giant growth (Postboot only)
Alternate Me Scares Me: Batch SW6 Salu is intimidated by her tougher, more bitter 5YL counterpart, at least until she gets to know her better.
Foregone Conclusion: Invoked but averted. Postboot Star Boy learns that the Starman that succeeded Jack Knight in the 21st century is him in his future, but Jack tells him that the future can always change. Lo and behold, the future Starman later turns out to be Retroboot Star Boy instead.
Gravity Master: Most versions of the character could only make things heavier. The Retroboot version can also make things lighter.
Legacy Character: Retroactively. Though not originally conceived as such, later continuity connected him to the Starman mythos.
This was also true in preboot/current continuity. Star Boy's first appearance showed him having many powers, while his later appearances showed the gravity powers. This was explained away with a story explaining that he had had the gravity powers from birth and the others were temporary.
Weaksauce Weakness/Bizarre Alien Biology: In threeboot, he's more or less diabetic because people from Xanthu can't break down sugars properly. Unlike most Weaksauce Weaknesses, this is only mentioned in a throwaway scene and never actually used against him.
Sun Boy/Inferno I
AKA: Dirk Morgna
Abilities: Solar energy generation and manipulation
The Chew Toy: His deaths throughout the various verions of the Legion. His FYL counterpart was rendered a perpetually burning corpse before he was shot in the head, the Threeboot Dirk had his head completed destroyed by Superboy-Prime, and now his post-Flashpoint counterpart dies from a crushed skull and then has his body cooked and devoured by the natives of the planet his team crashed on. At least he was able to go out like a hero.
Demoted to Extra: Postboot, though he still gains his solar powers (albeit for only a short time, and less controllable- while he has them, he glows so brightly that he needs a tinted transuit to keep from blinding or burning people).
Face-Heel Turn: In 5YL, Sun Boy becomes a willing pawn of the Dominators.
Freudian Excuse: The FYL Dirk had a really crappy childhood due to an absent mother and a jerkass lecherous father who taught Dirk that all women want a man who is a jerk and that if you don't win you're nothing, which instilled in Dirk the sense that being amorous and boastful would help him get women and that he had to be better than everyone else.
Gender Flip: Subverted. A female Inferno appears on the WorkForce in the Post-Zero Hour continuity, but she turns out to be a different person than Dirk Morgna.
Heroic BSOD: Retroboot, after he's imprisoned and tortured by Earth-Man. He gets better after seeing his Threeboot counterpart get murdered by Superboy-Prime.
Ignored Epiphany: SW6 Inferno swore he would become a better person and avoid the same fate as his older counterpart... only not.
Jerkass: Inferno was an insufferable, lecherous pig.
Manchild: During Dirk's dreams of his failed tenure as leader following the Black Dawn incident, his inner thoughts revealed that he believed his teammates were leaving because they were all jealous of him for being so awesome.
Parental Neglect: FYL and SW6 Dirk. Averted in regards to Threeboot Dirk, whose parents were very understanding and openminded towards the Legion's goals. Though, this ticked Dirk off somewhat, and he left the Legion because he felt he was only a member because of his parents and not because he wanted to be with the team for himself.
Really Gets Around: Has had a lot of girlfriends, though this stops at Postboot and Threeboot Dirk.
Redemption Equals Death: His Five Years Later counterpart decided to finally do some good, only to have the people of Earth reject him for being a sell-out. He's then caught in a nuclear blast and his powers are warped to the point that he's rendered a perpetually burning corpse until his lover Circe puts a bullet in his skull. His body then gets hijacked by Wildfire.
Parental Substitute: Apparition's baby boy Cub Nah began to see Brin as more of a father than his actual father, which is understandable because Brin was the only father figure in his life when he was first born.
Took A Level In Jerk Ass: His Threeboot counterpart after he received a power upgrade. He became stronger and faster, but he also became more aggressive and threatening to his teammates. Slightly Justified by the reveal that Saturn Girl had been exerting a bit of control over his emotions to keep him in check for a while.
Jerk with a Heart of Gold: One of his outbursts is caused when he's thanking, in his own way, future teammate Giselle for helping in a battle, and learning that the reason why she wasn't with the rest of the citizens in the safety zone was because the city manager locked her out on purpose. He then attempted to tear said manager's throat out before Saturn Girl intervened. Some of his other outbursts after that could be contributed to his overprotective nature with Princess Projectra.
Duality Motif: She can split into two people, and in some versions has two eyes of different colors. This is strange since 1) she had the ability to split into three before one body was killed, but didn't have three eyes, 2) it's a planetary power and other people from the planet don't have this, and 3) when she splits, each body has two of the same color eyes, making it impossible for her to pretend to not be split when she is.
Last Of Her Kind: Threeboot Triplicate Girl started out as an amnesiac in the ruins of a world called Cargg, and eventually duplicated enough to repopulate it. She/they sent one of her as an ambassador to the United Planets, who became a Legionnaire... but can't go home again. See Stranger in a Familiar Land, below.
Literal Split Personality: Postboot, each duplicate embodies a different personality aspect. Preboot and Retroboot are more Single Minded Triplets (see below). Threeboot is a whole other story originally, but works out similarly to the Single Minded versions.
Me's A Crowd: Probably one of the more interesting variations.
Power Perversion Potential: A mild example; early in her relationship with Chuck Taine, she split into two people and each of her selves kissed Chuck on both cheeks at the same time, which he seemed to enjoy.
Wicked Witch: Her Postboot incarnation invoked this trope in her appearance, though she was more amoral than evil. Then she got de-aged into an attractive twenty-something and became a lot more pleasant.
The Mole/A Wolf in Sheep's Clothing: Impersonated Shrinking Violet when Violet was kidnapped. Yera was not told of their plans and didn't believe she was assisting in any crime. She ended up marrying Colossal Boy while in disguise, although the marriage did not end when she was revealed.
Easily Forgiven: Justified, as she not only had started to question her superior's orders, but had done none of what she did out of malice. However, it's been a plot point that Shrinking Violet is not fond of her at all, to the point of flat out warning Yera to never use her form again no matter what. In the Five Years Later Legion Vi and Yera reconciled their differences, but in the Johnsboot Legion Myg (the second Karate Kid) pointed out the tension between Vi and Yera as an example of how the Legion is a joke.
Abilites: Superfast Flight (including though the vacuum of space), Stun "Comet" Gas release
Ascended Fangirl: Wanted to be a legionarre, to the point she went though a dangerous comet trail just in the hopes of giving herself powers,which ended up paying off. Decades later realworld time, after stints as both a legion cadet and a substitutie legionarre, she finally became a full fledged legionarre post reboot.
Redeeming Replacement: Of Legion villain Computo, the sentient computer who posessed her in an earlier story (giving her powers in the process). She's also the younger sister of the second Invisible Kid.
Technopath: She can "speak" to and control computers.
Stuffed into the Fridge: Her Five Years Later counterpart. There was a supporting character with the same skin tone as Dawnstar who called herself "Bounty", and she was an Anti-Hero bounty hunter with a vague backstory. It turned out that she was really Dawnstar, being possessed by a demon called Bounty that amputated her wings. Unlike Lightning Lad and Shrinking Violet, who both had their limbs grown back, Dawny's wings were never restored. And then Zero Hour happened, and that was the last fans saw of her until The Lightning Saga.
During Legion of 3 Worlds, artist George Perez drew the wingless Dawnstar deliberately behind where Cosmic Boy's word bubble would be placed.
Teleporters and Transporters: Thanks to his DNA being different from Lyle Norg's, he developed this as a secondary power from the serum. However, it was activated by adrenaline and he couldn't control where he ended up, which meant that every time he was startled, or angry, or fighting, he might get sent who-knows-where. Thus, after he accidentally teleported himself and Wharlik, a Khund he was fighting, into space, he had it removed.
Characterization Marches On: Paul Levitz, despite ignoring him in the 1980s, has devoted enough effort in the current Legion volume to move Tyroc beyond his previous "angry black man" personality and make him likable. For the most part, its worked.
Executive Meddling: How he was created. The writers and artists were all equally disgusted that the editors forced them to include a black character who was both a stereotypical angry black man and a racial separatist, in a time when racism should've been eliminated. Paul Levitz ignored him completely during the 1980s.
Green Lantern Ring: His superpowered screams can do basically whatever the writer likes. (Though after a while most writers just treated them as destructive blasts.)
Writer Revolt: No one liked the idea behind this character, especially given that the writers had previously tried to introduce black characters. Mike Grell intentionally made his outfit stupid, comparing it to a cross between Elvis and a football player.
AKA: Drake Burroughs
Abilities: Composed of anti-energy, energy blasts and manipulation
Fusion Dance: Postboot, Wildfire was created by the fusion of the powers and souls of two dead heroes, Randall "Atom'X" Burroughs and Jahr-Drake "Blast-Off" Ningle.
The Heart: Postboot, but not in the main series itself. Two Flash Forward series—Legends of the Dead Earth and DC One Million—show Wildfire as the only surviving member of the original Legion in both the 57th and 853rd centuries, respectively, having kept the Legion name alive all that time.
Abilities: Super-strength, speed, senses, flight, and invulnerability
The Atoner: After the Daxamite attack on the Postboot United Planets, she joins a convent to atone for her sins.
Defector from Decadence: In the Postboot continuity, she was raised in a racist cult, but turned over a new leaf (a while) after she joined the Legion.
Defrosting Ice Queen: Before turning over her new leaf, Postboot Andromeda was a hugely racist bitch, only agreeing to join an interspecies, pro-integration organization like the Legion because being a superhero surrounded by "lesser races" still beat being an ordinary teenager going to school back home, where she didn't have any powers.
Expy: Of Supergirl, when that character was removed from the Preboot timeline. Her Postboot name was taken from Laurel Kent, Superman's descendant and Legion Academy student from the original continuity.
The Mole: In the Postboot, Laurel was secretly a member of the White Triangle, and gave the Daxamite-led group the formula to the serum that protected her from lead.
Weaksauce Weakness: Like all Daxamites she has a fatal allergy to even trace amounts of lead. In all continuities where she exists, Brainiac 5 developed a serum which soon rid her of the problem, but early on in the Postboot she had to wear a transuit at all times to avoid exposure (and actual physical contact with the "lesser races").
AKA: April Dumaka
Abilities: Super-human strength and speed, enhanced senses, and claws
Touched by Vorlons: She got her powers from gene-altering experiments performed on her by the Dominators.
AKA: Xao Jin
Homeworld: New Shanghai Colony
Ambition Is Evil: His desire to get his powers back Postboot led him to inadvertently release the Elements of Disaster, who almost destroyed the United Planets.
Canon Immigrant: He first appeared in 5YL as a new member to join the SW6 Legionnaires; he later reappeared in Postboot, albeit not as a Legionnaire. He briefly turns up as one of Mordru's undead warriors (in the Preboot universe) in Legion of Three Worlds.
Abilities: Super-strength, speed, durability, and healing abilities
Captain Ersatz: He was blatantly created as a stand-in for Superman, though not a direct stand-in as Mon-El was made to replace Kal-El's role as the Legion's inspiration, and Kent was seemingly created for the sake of having another Superman-esque Legionnaire.
Plot-Relevant Age-Up: Inverted, as Glorith turned him into a kid with all his memories intact the last time the Legion fought her before Zero Hour.
Remember the New Guy: He shows up in issue 12 with almost no introductory build-up. Though this is not as blatant as most examples, given that during the Five Year Gap it was likely that there would've been new Legionnaires who joined in that time.
Ret Here: A living example, as he was created as a result of Glorith rewriting the timeline.
Sacrificial Lamb: Postboot actually showed his induction into and first mission with the Legion—during which, of course, he died, becoming Leviathan's Greatest Failure in the process.
Time Stands Still: He augmented his ability with a "stasis belt", which failed at the worst possible time.
Alias: Sussa Paka
Abilities: Web-like hair
All There in the Manual: Her "Who's Who" entry states that, while she is from Earth, she was chosen by the matriarchal society of the planet Taltar as an agent to stage a coup on Earth and thus gave her her powers.
Animal Motifs: Her "web-like hair" which became more web-like after she died it grey.
First Girl Wins: Inverted with her Reboot counterpart, who had been dating Ultra Boy while he was with the Workforce only to lose him to Apparition.
Mythology Gag: This is a reference to the fact that she lost Ultra Boy to Phantom Girl in the continuity that preceded the Reboot Legion.
Heel-Face Revolving Door: Depending on the continuity. Her Pre-Crisis counterpart was evil, FYL counterpart went from lovable thief to legitimate hero, while her Reboot counterpart was kind of self-serving neutral but not evil, and her Johnsboot counterpart was once again evil.
Really Gets Around: Her list of boyfriends across continuities include Earth-Man, Radiation Roy and his Reboot counterpart Radion, FYL and Reboot Ultra Boy, and she once made goo-goo eyes to Lightning Lord.
Screw This, I'm Outta Here!: During the Silver Age when the Legion broke up Tarik the Mute's supervillain school, Sussa fled during the battle with the Legion.
You Gotta Have Blue Hair: She dyed her hair to a shade of blue after she changed her codename to Wave. Her Johnsboot counterpart dyed her hair to a shade of grey to play up the spider aspect of her name by giving it a literal web-like appearance.
The Call Knows Where You Live: Unlike almost every other Legionnaire, he was not a volunteer. His planet drafted him so they'd have a representative on the team.
Canon Immigrant: Postboot is the only Legion continuity with a Gates. In Legion of Three Worlds, he notices and calls speciesism on the parallel universes. He joins the Retroboot Legion to even things out a bit.
Portal Cut: Ra's al Ghul loses most of an arm being cut off by the edge of one of Gates's portals being used to rescue someone from the villain's grasp, taking the arm with him. This is the first indication that the portals which he's been using for years have sharp edges, which is kind of terrifying when you consider that he can create and move them about at will...
Soapbox Sadie: Most of his dialogue consists of complaining about the "capitalist police state" he's been drafted into.
Strawman Political: He's a revolutionary communist, and most of his appearances make fun of him for his extreme views. This doesn't stop him being an interesting and well-developed character, though.
However, his beliefs turned into a Chekhov's Gun when the Legion was being controlled by the Emerald Eye of Ekron, as his political viewpoints and philosophical outlook were so strong his willpower managed to shake off the Eye's control and regain a brief sense of self before he was turned into an egg.
Important Haircut: She sported a curly hairstyle for a long time before getting her hair cut shorter around the time of the Legion volume just before the Threeboot Legion.
Jerk with a Heart of Gold: Originally. She hated the Legion because she blamed them for her brother's death, but was still heroic in her right. After some time, she decided to leave the Uncanny Amazers and joined the Legion, eventually being elected their leader.
And I Must Scream: After she was killed by Superboy-Prime, Mordru absorbed her essence into himself, which the White Witch explained meant he absorbed all her magic, her spells, pretty much her soul, into his being. Mysa promptly did the same thing to Mordru and absorbed his body and power into herself, turning her into the Black Witch. It's unknown if Zoe is still alive in some way inside Mordru, inside Mysa.
Demoted to Extra: He spent all of ten issues as a member of the Legion before getting summarily depowered, was given just enough development to be interesting, and then mostly got relegated to the background before the Legion Worlds miniseries finally managed to abandon the character in a way that gave him no resolution but also left him in a position from which it would be hard to bring him back into play. And then the Legion's continuity was rebooted entirely a few years later anyhow.
Depower: Dyrk loses his powers in the fight against Mordru, and ends up as part of the Legion's support staff when the team won't give up on him.
Expy: Of Preboot Pol "Magnetic Kid" Krinn, arguably. Pol, Cosmic Boy's little brother, also appears in Postboot, but never joins the Legion; instead, Magno is the one who struggles with being overshadowed by Cos.
Middle Child Syndrome: Averted. He's the second of four children, but the truth is his older brother Omar is the one who constantly feels the need to assert his superiority. His parents are shown to be loving and supportive towards Dyrk, if somewhat blind to Omar's cruelty; his little sister Trin openly idolizes him to the point that she was devastated that Dyrk had to leave the Legion because she felt it wasn't fair to him. All the while Omar grumbles about not getting enough respect when Dyrk ignores his needling and insults.
Replacement Scrappy: In-universe, several characters - most notably Live Wire - treated him this way after he joined the Legion in Cosmic Boy's absence. Some fans see him this way as well, even though his character was never actually presented as a replacement for Cos, who was still a series regular (just stranded in the past).
Ship Tease: While XS is depicted as crushing on a number of different guys, Dyrk was the first one to show interest in her... which she didn't notice until after she'd accidentally brushed him off. And then the timeline ended.
What Happened to the Mouse?: In Legion Worlds #3, Cosmic Boy promises to let Dyrk, now a Sci-Cop, in on what the Legion is up to (the construction of Legion World and their return to active duty) as soon as he has a chance. The Legion ran for a year or two after that, but even when Cosmic Boy is shown returning the planet where Dyrk is still presumably serving as a police officer, Dyrk is never mentioned again and has yet to appear in any subsequent versions, not even L3W.
AKA: Candi Pyponte-Le Parc III
Apron Matron: A young version, as she's always calling her teammates "dear" and watching out for their emotional well being without being overbearing.
My Species Doth Protest Too Much: Sort of. In the peaceful, community-minded culture of her species, Shikari's wanderlust and more warlike tendencies make her something of a throwback.
The Nicknamer: Of sorts; some quirk of culture or language leads her to call her teammates names along the pattern of "X Legion" - Brainiac 5 became "Smart Legion" or "Green Legion," Umbra is "Dark Legion," etc. Possible explanation is that she is from a such different part of the universe that even the translated interlac sounds too weird to her.
Canon Immigrant: In the Legion annual that wiped Postboot from continuity and established Threeboot, Shikari was accidentally trapped in the Threeboot world. This clearly earth-shaking development was never followed up on, and she simply reappeared with the Postboot Legion in Legion of Three Worlds saying "Oh, there you guys are."
Scarily Competent Tracker: This is a racial ability, which eventually leads to Kwai navigators being implemented as a means of using "thresholds" for personal interplanetary teleportation throughout the United Planets, because the Kwai can navigate in the other-space that threshold technology moves mass through.
Abilities: Super-strength, speed, senses, flight, invulnerability, and tactile telekinesis
Fish out of Temporal Water: He was stuck in the Legion's time period for a while, but simultaneously appeared in Teen Titans... eventually, Teen Titans had a crossover with the Legion in which he disappeared from the 21st century, then came back moments later, having traveled to the point in the Legion's timeframe where he first appeared, then spent several months there before being sent back to get the Titans and bring them to the future for a time-traveling team-up.
Older Alter Ego: Like Captain Marvel. She's around 10 or 12, but her super-powered form appears around 16.
Put on a Bus / Brother Chuck: It was established early on that only Thunder had been sent to the Legion's time period; when she changed back to Cece, she appeared in her home time, and when she transformed again, Thunder was back with the Legion. After "Legion of the Damned", which destroyed the stargate system and made interplanetary travel take months or years again, the Legionnaires are devastated by the sudden distance separating them from friends and family, and Thunder, realizing she's lucky enough to be able to visit her parents without a ship, says the magic word and returns home. She says she'll be back, but the timeline ends before she's seen again.
Shout-Out: Her name and home planet are in-jokes on Captain Marvel creators C.C. Beck and Otto Binder.
Retcon: Geoff Johns wrote that Jenni is originally from the main DC Earth, along with Bart and their parents, and that the families migrated to Earth-247 to hide from Professor Zoom and his soldiers.
Strapped to an Operating Table: Her origin story has her growing up without superspeed, despite being the granddaughter of the Flash and the daughter of one of the Tornado Twins- until, in an attempt to understand and duplicate her bloodline's powers, the Dominators abducted her, and the trauma of their experimentation triggered the emergence of her powers.
Cassandra Truth: Nobody listens to him because they're bitter about his status as (more or less) an affirmative action hire. The fact that he's a precog like the original Cassandra makes this even more appropriate.
Replacement Scrappy: In-universe, almost no one liked him or wanted him on the team for a number of reasons pertaining to the fact that he was drafted by Naltor's government and was not recruited by the Legion himself.
Misunderstood Loner with a Heart of Gold: She's considered a freak by her own society because of her powers and appearance, and even her parents seem to slightly think she's a lost cause. She also got off to a rocky start with the Legion, considering them "sell-outs", but she does help a squad of Legionnaires by telling a group of Science Policemen they went the other way.
Weaksauce Weakness: She needs a steady power source to fuel her energy projection powers. This also makes her fairly redundant.
Abilities: Bonded to clairvoyant symbiont
Chuck Cunningham Syndrome: Following Mark Waid's departure, Theena appeared for only one panel the next issue and then completely disappeared from the series.
Mauve Shirt: She's one of the hordes of teens camped outside Legion headquarters.
My Significance Sense Is Tingling: The strange "screens" on her psychic symbiont's appendages allow for remote viewing of almost any location in the universe. She usually uses them to help the Legion's allies keep tabs on them.
AKA: Bogdan Tarka
Nigh Invulnerable: His only power is that he's ridiculously hard to harm (though it is possible). This was deemed cool, but his lack of offensive capabilities sent him to the Legion Reserve.
Petting Zoo People: Doopans are all very turtle-like, but evidently Turtle is especially durable.
Difficult but Awesome: His powers, which took quite a bit of study just to get to the point he could join the academy, and even as a Legionarre he's still learning to control them, but their potent enough to take down a full grown daxamite and clinch the legion's difficult against him.
What Kind of Lame Power Is Heart, Anyway?: Averted. While he's still hasn't fully mastered his power, he has doubts more due to a lack of experince and control of his powers than any doubts about what they can do. Luckily his teammates are fully aware of this.
AKA Mayra Pai
Abilites: Fire Breath, Acid Breath and Acid Absorbtion
Badass: Is able to take on a gang of powerful thugs until backup arrives for starters.
Canon Immigrant: Sort of. First appeared in the reboot era, and came to the present as part of a story where several Legionnaires were stuck in the present day. When they returned to the future, she stayed in the present. Since she was not Put on a Bus with the rest of the reboot, she could in theory show up at any time. A green-skinned version also appeared in the Threeboot.
Abilities: Manipulates plant growth; claims he can talk to them, which he cannot
Green Thumb: Essentially taken to its logical conclusion - he can accelerate the growth of plants, and that's his only power. The inability to actually control plants is the largest reason for him never being accepted
Heroic Build: Originally played straight when he was first introduced in the Silver Age, up until the 1980s when the Subs were rewrote as a group of incompetent fanboys, and he was made rather obese. Following the return of the "original" Legion, he was slimmed back down.
Heart Is an Awesome Power: When it can turn Green Kryptonite into harmless Blue Kryptonite, when you can use it to turn the air black (remember, Night Girl is his teammate), and when you need an effective disguise or you want to disorient your foes.
Abilities: Breathes fire with moderate control at best
Unskilled, but Strong: The reason his membership has been repeatedly denied. His fire breath is incredibly potent, but he lacks the ability to control it in any meaningful way. The original incarnation even had terrible allergies that would often activate his powers. Preboot, he would eventually achieve a level of control that was frankly ridiculous, capable of making ice sculptures with his fire breath, but this would be ignored in Retroboot.
AKA: Drura Sepht
Abilities: Spontaneous generation of infectious diseases
Put on a Bus: In Retroboot, she was banished to Limbo by Earth-Man (where she joined up with Doctor Thirteen and a Nazi gorilla).
Unskilled, but Strong: Like many of her teamates, her inability to control her powers is her downfall. In her second attempt to apply for Legion membership, she boasts that she's much more powerful than before and can even cause epidemics... but her control hasn't improved remotely.
What Kind of Lame Power Is Heart, Anyway?: Initially, she could only give people aches and sniffles. Afterwards, she averted this by becoming much more powerful; it's just that she lacks meaningful control over her diseases.
Heart Is an Awesome Power: In the last postboot story, Drura is introduced as a Legion cadet, airlifted in as part of emergency backup during a riot in Metropolis, and demonstrating much greater control of powers than the previous version, reduces two dedicated terrorists to vomiting bags of sick who eagerly give up the location of their ringleader.
Infectious Lass: Hi, fellas. You're now officially walking hot zones.
Arrow: I'm... I'm willing to die for my cause.
Chameleon: Oh, you'll die. We'll all die someday. The issue is, do you want to die in your bed surrounded by loved ones... or bent over in this alley with a woefully inadequate supply of tissues?
Unskilled, but Strong: His quills are extremely harmful.. to friend and foe alike, since he can only shoot them all at once and in all directions surrounding him.
AKA: Dori Aandraison
Abilities: Wields the powers of the mysterious emotional spectrum, resulting in unpredictable mood swings
Mood-Swinger: She doesn't have full control over her power to tap into the emotional spectrum, which leads to her going from raging mad to hopeful to cocky and willful in the space of a few panels.
AKA: Dag Wentim
Abilities: Able to transform his body to stone, but forced to remain inanimate
Heart Is an Awesome Power: He even won a contest held by the Legion proper with membership as the prize, which he rejected because he couldn't bear to abandon his friends.
The Stoic: Often characterized as being an extremely taciturn and serious individual
Stone Wall: Essentially invulnerable in stone form, but incapable of movement.
Taken for Granite: What his power amounts to, turning into an immobile statue. Eventually, Preboot Stone Boy learned how to turn just his fists to stone, but this is usually ignored by other incarnations.
Being Tortured Makes You Evil: Falyce was implicitly stated to have been used a plaything for an Orandian duke who blinded her right eye so badly it was just one giant scab. This is what made her so susceptible to the Eye's power.
Legacy Character: Several women have posessed the Eye — or been turned to the dark side by it when they caught its fancy.
More Than Mind Control: The Eye exerts some control its user. Cera Kesh made a psychic plea to Saturn Girl to free her before its implied the Eye fully took over, and Sarya begged Sensor Girl to free her from the Eye's grasp.
The Dark Chick: More so than the Empress even (who's often The Big Bad). He's definitely weird, and has been known to clash with the other members, especially in later versions of the story. Played up in the cartoon; in the comics he might be closer to The Evil Genius.
The Faceless: His entire species resemble shadows, and as such, have no faces.
Poisonous Person: His touch causes the bonds between atoms to break down, resulting in disintegration.
Power Creep, Power Seep: An extreme example: while his Preboot origin story features him using his disintegrating touch to destroy his entire homeworld and everyone on it, he was never even remotely that powerful in any of his actual appearances, where plenty of characters can survive zaps from his hand.
Red Right Hand: Yellow actually. It really stands out on his shadowy black body.
Two-Faced: His left side is completely robotic, while his right side is flesh.
We Can Rebuild Him: He was once a common thief, but his left side was vaporized when he was apprehended. The authorities rebuilt him, turning him into a hyper-intelligent cyborg in the process. Nice one!
The Berserker: Sometimes slips into Unstoppable Rage mode. It's the reason he's to be executed in the original comics, despite not being an actual villain: he's simply too dangerous to leave alive.
Cool Helmet: Sometimes pictured in a space suit and helmet.
Demoted to Extra: He's one of the founding members of the Legion of Super Villains, but he doesn't get nearly the screen time of Saturn Queen, Lightning Lord, or even Sixth Rangers like Nemesis Kid.
Extra Ore Dinary: Has displayed magnetic powers on occasion, despite it not being his main ability.
Evil Counterpart: To Cosmic Boy, though their powers are vastly different. In fact, his powers make him more like Element Lad or Chemical King. As the leader of the original Terrible Trio however, he is very much the Evil Counterpart to Cos.
The Exile: Kicked off of Venus for practising transmutation.
Eye Beams: His transmutation rays usually come out of his eyes.
Antihero: Threeboot only, where he leads a black ops superhero team.
Arch-Enemy: To his brother and sister in the Preboot, Postboot, and Retroboot continuities.
Artistic Age/Younger Than They Look: He looked about sixty in his original appearances. Later versions have been better about this, but the combination of his ravaged face and white hair still make him look a lot older than his younger brother.
Badass Moustache: In the original comics, though this was dropped even by the end of the Preboot.
Cain and Abel: With Lightning Lad and Light Lass, his two younger siblings. In the Preboot continuity he was still rather protective of them despite this, while in the Postboot continuity he hated them both.
Corrupt the Cutie: Preboot he would repeatedly try to get Light Lass to come over to his side.
Death Seeker: In the Threeboot, where he's an unbalanced antihero looking to die.
Evil Old Folks: Has this look in the early years of the Preboot. Since the initial Legion of Super Villains are from even farther into the future than the Legion of Super Heroes it may not even be Artistic Age.
With Great Power Comes Great Insanity: Invoked in-universe during the Reboot. Live Wire believed that the lightning abilities which the three of them gained would wind up corrupting them, which is why Mekt became a criminal. When Garth finally confronted his brother with this theory, Mekt rebuffed it, and Ayla finally managed to convince Garth that Mekt was always rotten... after Mekt had destroyed Garth's right arm.
Word of Gay: His Preboot version was gay, but the most we ever see of this is in one issue where a man named Holt introduces himself as Mekt's "friend". Bierbaum stated this didn't come up simply because, by this time, Mekt had faded into the background.
Card-Carrying Villain: In the original comics, there was no crime on Saturn due to certain minerals in the rings (hey, it was the Silver Age). Upon coming to Earth, and getting out of range of the rings, she just decided, "hey I think I'll turn evil for the Hell of it."
Evil Matriarch: In "Absolute Power" and the Kandor arc of the new Supergirl series. She seems to have developed an obsession with having a child to serve as her Dragon. In both cases, she's gotten to watch said child die.
Oh, Crap: Delivers a fine one when he realizes that Projectra is going to destroy him.
The Mole / Sixth Ranger Traitor: He joined the Legion to spy on them for the Khunds. Later, he became a member of the Legion of Super-Villains.
Smug Snake: Thinks his abilities make him better than the Legionnaires.
Sixth Ranger: Joins the Legion of Supervillains long after its foundation, yet becomes the leader.
Turncoat: A legion member who sold them out to the Khunds.
Weaksauce Weakness: Adapts one power to defeat one opponent, which uncontrollably changes if he encounters another. Strength enough to beat Superboy would be nice to take into battle against a group, but as soon as he ran into, say, Phantom Girl it would turn into the ability to affect intangible people instead. And it turns out the ability to see through illusions isn't all great against the widow of the greatest martial artist in the universe. KRRACK!
Abilities: Copies the powers of those around him; shapeshifitng
Dark Is Evil: His now black hair and cloak evoke this, as well the storm clouds he can generate.
Heel-Face Turn: His Five Year Later counterpart actually got over his rejection and went on to work with weather-generating machinery, before joining the Legion when they were desperate for members during the Five Year Gap.
Motive Decay: His original reason for joining the Legion was a stunt for a fraternity. In the Johnsboot continuity he claims that he very badly wanted to join the Legion and considers them amoral bullies for not understanding what that kind of rejection does to someone.
Kryptonite Factor: Mordru suffers from a crippling phobia of being buried alive. A Shout-Out to its origin appears many years later: "We all make our own weaknesses, his from a nightmare happenstance long in his past." In his first appearance, at the climax of the story, after trying the Legion for "acts of anti-crime" and sentencing them to death, Mordru "gathers the power to annihilate worlds, to shatter suns, preparing to hurl it at the helpless heroes." But the cavern they're in can't endure the stress of the leaking energy. The end result is Mordru and his "devil's jury" are buried, the Legionnaires survive due to Mordru having trapped them in a powerful force field, and Mordru, who cannot die by any known means, but can't remain conscious without air, is sealed inside solid rock.
Fiction 500: Those who can remember his name know he's one of the richest and most influential men in the galaxy. Not that there's many who do.
Freudian Excuse: Built in. He had to stay in his parents' line of sight, so they'd remember to feed him. And then there was that bit where the government tried to capture him to learn how his powers worked.
Invisible to Normals: He has the unique ability to alter information with his mind—including recorded data and people's memories—making him effectively invisible.
Knight of Cerebus: If the Trapper is involved in a story it will inevitably feature mind rape and torture involving alternate lives.
Multiple-Choice Past: Probably the only character for whom this is an actual power—he has the ability to change his own past, down to his very identity. The Time Trapper has been, among others, Cosmic Boy, Lori Morning, and Superboy-Prime.
Or S/He could be all of those people, only from different futures.
Shoo Out the Clowns: At the end of the more lighthearted Peyer/McGraw/Stern era, in the issue before the Darker and Edgier DnA era began, Koko leaves the series to settle down with a female space monkey on a remote jungle planet.
