Spark

Ayla Ranzz, originally Lightning Lass also known as "Spark" is a super heroine in a future DC Comics universe. She is a member of the Legion of Super-Heroes. There have been three versions of Ayla since her original debut; these versions are separated by the events of both the Zero Hour and Infinite Crisis limited series. Ayla Ranzz (of the planet Winath, where twinning is normal) first appeared in Adventure Comics #308, (May 1963). She is the twin sister of fellow Legionnaire Garth (Lightning Lad) and the younger sister of the villainous Mekt (Lightning Lord). All three gained their lightning powers after being attacked by creatures called lightning beasts on the "lightning world" of Korbal.
