When Ayla refused to join them, her brother tried to kill her, though she survived and discovered that her original lightning powers had been restored.

[4] Ayla, known as Spark, originally joined the Legion as a replacement for her twin brother Live Wire, as their planet Winath decided to choose her rather than Garth, who had been classified as a runaway.

Her team helped the modern superheroes during the Final Night crisis, where Earth's sun was slowly being devoured.

Following another reboot of Legion continuity, Ayla Ranzz is again called Light Lass, and has gravity nullifying powers.

Brainiac 5 commented that he finds it aggravating that the ability to negate one of the fundamental forces is in the hands of someone who treats things so flippantly.

Ayla took a serious and active role in assisting her brother Garth when he became Legion Leader following Supergirl's return to her time.

Ayla also assisted Brainiac 5 and Star Boy in stabilizing gravity after an intruder planet appeared in the Sol system.

In the Lightning Saga, it was initially implied that she was presumed dead by Timber Wolf, who said "I'm coming, Ayla" as he was about to sacrifice his life.

Ayla was later seen in issue #6 of Paul Levitz's new Legion of Superheroes series, where she was shown preparing to go on a holiday vacation with Shrinking Violet.

In The New Golden Age, Lightning Lass is among the Legion of Super-Heroes members that arrive in the present and confront the Justice Society of America over their decision to recruit Legionnaire, a young, heroic incarnation of Mordru.

Ayla Ranzz as Lightning Lass appears as a character summon in Scribblenauts Unmasked: A DC Comics Adventure.
