Henry Hawley was the manager of the "Defend America League" which was actually a front for the "Destroy America League," a fifth column organization. As The Black Thorn, Hawley managed to steal the Mummy Ray rifle from its mad inventor, Phineas Cox. The Mummy Ray could instanty dehydrate a man, essentially mummifying him. Black Thorn used the ray to kill a number of American soldiers and to successfully blow up a munitions plant. He even managed to defeat Mr. Scarlet in combat, though he was taken into custody after being knocked out from behind by Phineas Cox.
