Iron Kid

A long-lost mechanical fist fastens itself to Marty's arm, giving an ordinary boy extraordinary fighting power. His discovery also makes him a target, drawing him into a struggle that began with the legendary warrior Eon.

As enemies pursue him and new companions come to his aid, Marty uncovers the connection between his family and the fist's original owner. Inheriting a weapon is one thing; learning to wield it is another. To protect those beside him, he must train to become the heir his enemies already fear.
