Sign Gene

Secret agent Tom Clerc is deaf and comes from a multi-generational deaf family. He is a descendant of Laurent Clerc or 'the Father of the Deaf in America' that brought the sign language to the United States two centuries ago. Tom is a carrier of "SGx29", a powerful Sign Gene mutation. However, he lost a significant portion of his powers during a fierce fight some years back against the main villain Jux Clerc, his own deaf brother and the leader of 1.8.8.0- an evil organization dedicated to exterminating Sign Gene mutants.
