Night Girl is Lydda Jath. Born on the sunless planet Kathoon, her scientist father gave her the power of super-strength. Unfortunately, this ability only works when she's not in sunlight. The Legion originally rejected her, and she became a founding member of the Legion of Substitute Heroes. Her romantic partner and later husband is Cosmic Boy. In Reboot Legion continuity, Night Girl is only seen as a member of the substitutes. In Prime Legion continuity, Night Girl is a member of the Legion Reserves.
- 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 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.
- The Big Guy: Played with. Night Girl is the literal chick, but her powers make her the team's powerhouse.
- Nigh-Invulnerable: When using this power, she is impervious to harm by extreme forces. If propelled at sufficient force, by either her flight ring or a super-toss, can use her dense body like a human missile, but only in darkness or deep shadow.
- Only Sane Man: She was pretty much the most grounded out of the Substitute Heroes, but she wasn't obnoxious about it or desperate for respect like Polar Boy was. As it stands she was largely exempt from the more comedic stories about the Subs because she wasn't as incompetent (except for the Brave And The Bold issue where the Subs teamed up with the Inferior 5 and accidentally destroyed Earth).
- Required Secondary Powers: She has the secondary ability to see in the dark. Necessary if you fight in the dark or come from a sunless planet.
- Super-Strength: Night Girl has the powers of super-strength, equivalent to that of Superboy or Mon-El lift far in excess of 100 tons, but only in darkness or deep shadow.
- Weaksauce Weakness: Her powers fade immediately in the presence of direct sunlight. Her powers can be negated by the presence of ultra-violet energy.
The wife of Gim Allon aka Colossal Boy. Being a native of Durla, Chameleon Girl has the power of shape-shifting. She is also an accomplished actress and once posed as Legionnaire Shrinking Violet for an extended period of time.
- Action Girl: Disguising herself as a Legionnaire meant going on Legion missions, and she pitched in as well as the real Violet.
- Distaff Counterpart: To Chameleon Boy, natch.
- Fantastic Racism: As a Durlan she's on the receiving end of this. She fights it by proving how talented an actress she can be.
- "Fantastic Voyage" Plot: Yera-as-Violet shrinks to get into the "Lydea Mallor" clone's body and expands enough to give the Servant of Darkness a fatal stroke.
- Green-Skinned Space Babe: Orange skinned.
- Happily Married: To Colossal Boy. The pair fell in love and secretly married while Yera was pretending to be Violet. There have been a couple of rough patches—like when he insisted on staying an active Legionnaire after being crippled.
- Interspecies Romance: As mentioned above, she's married to the (altered) human Gim Allon/Colossal Boy.
- Kryptonite Factor: Like all Durlans, being hit by a chemical called "cancelite" neutralizes her powers until its cleaned off.
- 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.
- My God, What Have I Done?: She was hired under the premise that Shrinking Violet was ill and wanted to take a leave of absence in secret. When she learned the truth, she was horrified, and immediately ratted on her erstwhile employers.
- Out-of-Character Alert: Suddenly after years of turning him down, Violet became romantically interested and flirtatious with Colossal Boy. Gim may have been too happy to notice how odd this sudden change was, but it was one of a number of mistakes that eventually led his teammates to uncover Yera's imposture.
- Parental Marriage Veto: Averted. Gim's parents were surprised he married a Durlan, but they were fine with it. They do want any kids to be raised Jewish, though.
- Power Perversion Potential: Implied during her first night with Colossal Boy after the truth came out.
- Sizeshifter: Part of her shapeshifting abilities. She couldn't get as small as the real Violet could, but she could get small enough that no one could tell the difference.
- Super-Senses: Yera, like all Durlans, scans the molecular structure of any object or person she encounters via the invisible emanations emitted from her antennae.
- Voluntary Shapeshifting: Like all Durlans, Yera possesses the ability to transform her body's size, shape and color to mimic any person, creature or object in the universe. Naturally she cannot duplicate super-powers unless they're inherent abilities of whatever form she's taken.

Comet Queen was a member of the Legion Academy. She "Graduated" to the Legion of Substitute Heroes. Post 52 reboot the Subs membership may have been retconned. She was recently inducted into the Legion.
- Ascended Fangirl: Wanted to be a Legionnare, 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 real-world time, after stints as both a legion cadet and a Substitute Legionnaire, she finally became a full fledged Legionnaire post reboot.
- Flaming Hair: Constantly emitting a fiery-looking gas of some sort from her head. Fortunately for everyone around her it's not poisonous or flammable unless she wants it to be.

- Future Slang: Peppers her speech with it.
- Genki Girl: Thoroughly jazzed about the Legion.
- Green-Skinned Space Babe: Orange skinned. Maybe a bit odder-looking than some.

- Savvy Guy, Energetic Girl: Teased with Polar Boy.
- Separated by a Common Language: Her constant use of slang makes it hard for people to understand what she's saying sometimes.
- Super-Speed: She is able to fly at super-speeds while trailing a stream of stellar energy, much like a comet does.
- Super-Toughness: Her altered body can stand up to the stresses of high-speed flight.
- Valley Girl: She's basically a futuristic version of one. She speaks her own brand of slang, much to the annoyance of nearly everyone she's around because half the time they have no idea what she's talking about.
- Verbal Tic: Makes quite a few cosmos, particularly star, related statements in her speech. It's unknown if this is a normal thing on Extal or if it's just her.
- Violation of Common Sense: "I wanna be in the Legion! I know! Star Boy got super-powers from the flaming tail of a comet once, so I'll go into space, strip naked and jump into the first comet I see!" She apparently forgot, didn't realize, or didn't care that Star Boy had been in a spaceship at the time.
- Audience Surrogate: To a degree
- 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 Legionnaire he's still learning to control them, but their potent enough to take down a full grown daxamite.
- Fakeout Makeout: With Dragonwing, to his displeasure and her delight
- Legacy Character: To Chemical King, albeit with a different name
- Ship Tease: With Dragonwing
- 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.
- Braids of Action: Her hair seems to be in braids and she's a legionnaire.
- Breath Weapon: In both acidic and firey flavors.
- Cain and Abel: The Abel of her sister Bao Pai's Cain.
- Dark and Troubled Past: The portion of earth she grew up on was rather seedy and is populated with gangs, one of which her sister joined
- Draconic Humanoid: Not in the conventional sense, but she has dragon-like eyes, breaths fire and spits poison.

- Technicolor Fire: Her fire breath is green.
- Cute Witch: She's quite cute for a sorceress.
