Second name that
Ayla Ranzz,
Lightning Lass, used as a member of the
Legion of Super-Heroes.
After having a vision that seven members of the Legion would die in an explosion, Dream Girl, a new recruit to the Legion, attempted to change the outcome of the vision by stealing the powers of Lightning Lass by drawing them into a large dynamo. Instead of stealing Lightning Lass's powers, the dynamo transformed them into the ability to make things "super-light," effectively negating gravity's effect on the object. Changing her name to Light Lass, Ayla Ranzz continued as a member of the the Legion.
