Editing Shadow Lass (section)

==Fictional character biography==
Tasmia Mallor originates from the planet Talok VIII, and possesses darkness-manipulating abilities, which she and her cousin Grev (Shadow Kid) receive from their ancestors' spirits. As her ancestors before her from the past thousand years, Tasmia is the hereditary shadow champion of Talok VIII. Her 20th-century ancestors, Lydea and Lyrissa Mallor, are also shadow champions and members of the interstellar police force [[L.E.G.I.O.N.]]

Her cousin Grev, who also wields the shadow power thanks to his bloodline, joins [[the Legion Academy]] as Shadow Kid, but knows that he cannot join the Legion due to a rule preventing members from having the same powers.

Shadow Lass joins the Legion after her homeworld is invaded by the [[Fatal Five]]. She helps the Legion to defeat them.<ref>''Adventure Comics'' #365-366</ref> After joining, she became romantically involved with [[Lar Gand]] and eventually marries him. Their marriage is rocky for years despite their strong feelings for each other, and Tasmia goes into mourning when Gand dies. He is possessed by the [[Time Trapper]]'s essence and temporarily resurrected before a cataclysmic battle erases the Trapper from existence.<ref>http://www.mykey3000.com/cosmicteams/legion/legion1/whoswho4.htm{{dead link|date=December 2017|bot=InternetArchiveBot|fix-attempted=yes}}</ref>

===1994 reboot===
{{Main|Legion of Super-Heroes (1994 team)}}In post-''[[Zero Hour: Crisis in Time!|Zero Hour]]'' continuity, Shadow Lass is raised by priests and separated from her mother to ensure their safety. After her mother is killed in battle, Tasmia gains her ancestors' shadow powers and joins the Legion as '''Umbra''' following a battle with [[United Planets]] diplomats.

Umbra is later among the Legionnaires who are lost in a space rift and transported to another galaxy. [[Saturn Girl]] attempts to telepathically calm her, but a telepathic matrix interferes with her powers, creating a shadow creature fueled by their pain before [[Brainiac 5]] heals them.

Umbra later returns to Talok VIII and discovers that her cousin Grev has cloaked the planet in darkness and had it withdraw from the United Planets. However, he is killed by the Shadow's power, and Umbra removes the cloak before leaving.

===Post-Infinite Crisis: Retroboot Legion===

The events of ''[[Infinite Crisis]]'' restore an analogue of the pre-''[[Crisis on Infinite Earths|Crisis]]'' Legion to continuity. Shadow Lass is included in their number, and is among the group of Legionnaires who help [[Superman]] defeat the [[Justice League of Earth]].

During the League's xenophobic reign, Shadow Lass works with [[Night Girl]], [[Timber Wolf (character)|Timber Wolf]], and [[Ayla Ranzz|Lightning Lass]] to help thousands of aliens escape Earth.

Shadow Lass is shown prominently in the teaser image for the ''[[Final Crisis: Legion of 3 Worlds]]'' mini-series, using her powers to keep [[Mordru]] and Saturn Queen in the dark.<ref>[http://forum.newsarama.com/showthread.php?t=152225 GEOFF JOHNS: LEGION OF 3 WORLDS, I - NEWSARAMA<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20081216122348/http://forum.newsarama.com/showthread.php?t=152225 |date=2008-12-16 }}</ref> In the story, she, [[Phantom Girl]], and Lightning Lass rescue [[Mon-El]] from the [[Phantom Zone]], where [[Kirt Niedrigh|Earth-Man]] had imprisoned him.
