Bond Forger is the pet of the Forger Family. Formerly known as Subject 8, Bond has been used for experiments that resulted in him gaining precognition abilities.
Bond is shown to be a very kind dog, as he uses his precognition abilities to rescue a child from being hit by a falling board. He also helps Anya Forger to retrieve her favorite pair of gloves from a fierce dog by intimidating him.
