Fan Casting Tyroc in Return to the DC Universe

Born in the racial separated island of Marzal, which is set in a parallel dimension appearing once every 2 centuries, Troy Stewart discovered his powerful sonic scream when saving friends from a demon from a neighboring dimension. For a time, Troy spent his life as Marzal Island's protector, before he would eventually become an outstanding member of the Legion of Super-Heroes, using his nickname of "Tyroc", which is Marzalian for "Scream of the Devil" as his code-name, bringing his sonic scream to help fight injustice everywhere.
