A member of the Legion of Substitute Heroes
Ral Benem is the real name of Chlorophyll Kid. As an child,
Ral fell into a vat of plant-growing solution. This contact
gave him the ability to grow any seed or plant superfast and to
an enormous size. Ral traveled to Earth from his home planet of
Mardru to try out for the Legion of Super-Heroes. The Legion
determined that Ral, who called himself Chlorophyll Kid, had a power
which would not be useful on their missions.
Chlorophyll Kid and the other candidates who were rejected that day
formed a group called the Legion of Substitute Heroes. The Subs, as
they were called, helped the Legion out on a number of ocassions.
