A member of the Legion of Substitute Heroes
Staq Mavlen is the real name of Fire Lad. After inhaling
strange vapors given off by a fiery meteorite, Staq gained
the ability to breathe fire. Calling himself Fire Lad, Staq
traveled from Earth from his native planet Shwar to try out for
the Legion of Super-Heroes. Fire Lad was rejected, because his
power was deemed too dangerous.
Fire Lad and the other candidates rejected for membership that day
created their own group called the Legion of Substitute Heroes. The
Subs as they were called aided the Legion on a number of occasions.
