Darryl Sheppard was only a young child when the U.S. Air Force transport plane she
was on crashed down on a small island to the north of Japan, leaving her the sole
survivor. The locals took the youth in, and raised her as a member of their community,
complete with their devotion to the martial arts. Then her adoptive home island was
invaded by a corporation with US military ties who proceeeded to perform hideous
experiments on the islanders they did not immediately execute for fighting back.
Eventually she was found and adopted by a U.S. Air Force Captain, Gideon Pierce.
She grew up to be a strong willed woman with a desire to do right, and when the
terrorists took control of New York's Museum of Natural History, she teamed up
with the Revengers (Megalith, Armor, SilverStreak) to stop them.
