Lightning Lad

Voiced by: Andy Milder

  • Artificial Arm: From "Chained Lightning" onwards.
  • Badass Beard: In season two.
  • Butt Monkey: He really hates Legion try-outs, usually because he winds up on the receiving end of someone's demonstration.
    • In the spin-off comic of the cartoon, during Infectious Lass's try-out, he wound up with a form of lava acne and got stuck with Bouncing Boy's power (and physique). What sucked worse is that, the virus that switched his power with BB's lasts longer on people with greater mass.
  • Cain and Abel: The Abel to Mekt's Cain.
  • Cynicism Catalyst: The death of his sister Ayla during the attack that granted him and his older brother Mekt their powers pushes them into their guilt-ridden Cain and Abel complex, along with Garth's cynical attitude and Mekt's path into villainy. Subverted in that she didn't die at all and was eventually restored to a physical form.
  • Fiery Redhead
  • Good Parents: He was seen embracing them after the storm that devastated Winath, happily embracing their children in the photo before he and his siblings got their abilities and him bringing Ayla home to see their parents.
  • Good Scars, Evil Scars: Lightning Lad's under eye mark.
  • He's All Grown Up: Has a shirtless scene in Chained Lightning to demonstrate this. Much to the joy of Legion fangirls everywhere.
  • Jerk with a Heart of Gold: While still this in season two, he'd softened a little. Not majorly, but considerably.
  • The Lancer
  • Locked into Strangeness: His scar and eyes are a result of the Lightning Beasts shocking him and his siblings that granted them their abilities.
  • Major Injury Under Reaction: "Sweet".
  • Real Men Wear Pink: Has surprisingly good bedside manner, as demonstrated by him trying to get Matter-Eater Lad to eat so he would recover quickly in the hospital. And then of course there's the fact that he loves his little, formerly twin sister dearly.
  • Shock and Awe
  • Teeth-Clenched Teamwork: With Dream Girl in season two. His reason for doing so is that she used to be a con artist fortune teller called Madame Mysterious, but the real reason behind his dislike is she told his parents that they would find his sister Ayla on another planet and it never happened, which devastated the two. Though their relationship has softened by the end of Nura's spotlight episode.

Voiced by: Michael Cornacchia

Phantom Girl

Timber Wolf

Voiced by: Shawn Harrison

Triplicate Girl/Duo Damsel

Voiced by: Kari Wahlgren

  • Bare Your Midriff: She wears this for the first series then only partially for the second series.
  • Despair Event Horizon: When one of the duplicates is seemingly killed.
  • Genki Girl: The most peppy and excitable of the female Legion members.
  • Literal Split Personality: Each of the three duplicates she splits into are semi-individuals with slight differences in personality to the point that they're both one person and yet also like very close sisters.
  • Me's a Crowd: When under the influence of magic her duplication power spirals out of control creating dozen of copies that continue to endlessly fill the Legion's spacecraft.

Chameleon Boy

Voiced by: Alexander Polinsky

  • Hero-Worshipper: In 'Who Am I' it was shown he's idolised Superman for years before he even joined the Legion.
  • Memory Gambit: Was a part of this for Brainiac 5's plan of infiltrating Imperiex's forces by impersonating Persuader.

Superman X/Kell-El

Voiced by: Yuri Lowenthal

  • Anti-Hero Substitute
    • Adorkable: His upbringing changed a lot but he retains a lot of Superman's personality traits and has just as awkward as a time fitting in with society.
  • Composite Character: Kon-El and Superman from the 853rd century.
  • Genetic Engineering Is the New Nuke: Created specifically to turn the tide against Imperiex in the 41st Century, he's the result of Superman's DNA being mixed with Kryptonite and as such is immune to the green rocks effects. It also has the added side effect of granting him different powers.

Cosmic Boy

Voiced by: Wil Wheaton

  • Unresolved Sexual Tension: With Saturn Girl. In "Chain of Command", he tried to protect her from harm's way, but she told him he can take care of herself and leaves before he can apologize. In the episode "In the Beginning", he's upset with Saturn Girl for always taking Lightning Lad's side.
  • What the Hell, Hero?: Lightning Lad calls him out for not even having the time to visit Saturn Girl while she's in a temporary coma.

Shrinking Violet

Voiced by: Kari Wahlgren

  • Ship Tease: She seems to spend a lot of time with Braniac 5.
  • Shrinking Violet: Averted, visually she gets smaller and wears dark purple but she does not have this personality at all.

The Fatal Five

Lightning Speed Vanguard/Legion of Supervillains

  • Fun with Acronyms: although doesn't spell out a word, the initials are the same in the old and later name of the team: LSV.
  • Heel-Face Turn: Although they weren't seen after their "turns", Lightning Lord and Ron-Karr.
  • Jerk Jock: Mekt "Lightning Lord" Ranzz in "Champions", before joining the LSV.
  • Jumping Off the Slippery Slope: The Light Speed Vanguard at first seem Cooler And More Effective Heroes, then Kinda Selfish Mercenary Heroes, then Ruthless Protection Racket.
  • Locked into Strangeness: Like his brother the Lightning Beasts shocked him and his eyes and hair changed.
  • Morality Pet: for Mekt in "Chained Lightning". Many years ago, dead little sister. Then, Not Quite Dead (which puts Even Evil Has Loved Ones back into play), followed by Unexplained Recovery. As he directly contributes to Ayla's restoration, he surrenders to prison without a fight.
  • Psycho Rangers: Each member is a counterpart for a Legionnaire.
    • Esper - Saturn Girl
    • Hunter - Timber Wolf
    • Lightning Lord - Lightning Lad
    • Ron-Karr and Wave - Bouncing Boy and Triplicate Girl (as the team's ship crew)
    • Tyr - Superman

Dr. Londo

Voiced by: Harry Lennix (Season 1), Dorian Harewood (Season 2)

  • Abusive Dad
  • Archnemesis Dad: To Timber Wolf, if he's got an episode to himself expect Dr. Londo to be the main villain
  • Evilutionary Biologist
  • Evil Counterpart: To President Winema Wazzo believe it or not:
    • Both have titles in front of their names, related to their professions and are referred to as such (President Wazzo and Dr. Londo)
    • They are single parents to their children (who're the same gender as their respective parents)
    • Their children are in the Legion of Superheroes and are close friends.
    • Their children resemble them in some way (for example, take away the werewolfism and his son has his facial features and hair. In a few glimpses of his son's human form he does look like a younger version of his father)
    • They both meddle in their children's lives. The key difference is Winema is well-meaning and ultimately wants what's best for her daughter while Londo only is interested with what he wants and doesn't care what happens to his son, he just wants his weapon/general.
  • From Nobody to Nightmare: In the original comic series he was only used for the purpose of flashbacks with little if any character development but when the animated series came along he may be as bad of a parent as Ozai
  • Guinea Pig Family
  • Jumping Off the Slippery Slope: At first appears as a lone, grieving scientist who's lost everything to the creature in the forest. As it turns out his son isn't dead but is the creature Londo told the Legion about he attempts to kill/capture the Legion and take his son back by force using his animal test subjects.
  • Karma Houdini: One of the very few villains of the series not to be either imprisoned on Takron Galtos, sent to the Phantom Zone or killed
  • Manipulative Bastard: Uses the Legion to capture his son, and during Timber Wolf's calling the old man out routine in S2 he points out that his father uses everyone this way
  • Meaningful Name: Dr. Mar Londo
  • Morally Ambiguous Doctorate
  • Never My Fault: Thinks Timber Wolf should be thanking him for changing him into a werewolf-monster.
  • Professor Guinea Pig cloned himself at least three times in his second appearance
  • Reverse Arm-Fold
  • Skunk Stripe: Like father, like son
  • Slasher Smile: Shows this during his Villainous Breakdown when he frees his mutated animals to attack the Legion and his son. Needless to say it doesn't turn out so well, for him
  • We Can Rule Together: Does this in 'Cry Wolf' with his son except it involved having to use a mind controlling device and giant golems to pummel him. Great parenting.

Brainiac 1.0

Voiced by: Corey Burton

  • Bald of Evil: As is traditional, he has no hair. When Brainiac 5 takes damage while he's stealing his body, Brainiac 5's base body loses its hair as it undergoes repairs.
  • Big Bad: Outright murders Imperiex and then takes control of his operations.
  • Enemy Within: Being Brainiac 5's predecessor, he is inevitably in his programming, but was left dormant. When Kandor was invaded by Imperiex, Brainy decided to ask for his assistance, which means Brainiac 1.0 got a foothold in his mind, which is exactly what Imperiex wanted.
  • Knight of Cerebus: Perhaps even moreso than Imperiex. Namely, his first appearance in Brainiac 5's head was followed by a number of Breather Episodes, and after those were done, he then became the central antagonist in the ending two-parter.
  • Not Quite Dead: After all is said and done in Season 2, it cuts back to Brainiac 1.0 putting himself back together in a new body, completely separate from Brainiac 5.
  • Villainous Breakdown: He starts attacking far more aggressively when Brainiac 5 gains control again, and then screams after being impaled.
  • Walking Spoiler
