Sparring partner to Iron Fist, Bob is a former member of the Sons of Tiger martial arts team. During his time with the Sons of Tiger, he and some other highly trained martial artists used their skills in hope of bettering their world. During one of their adventures, he met Iron Fist and the two soon became friends. To such a degree that, when Danny Rand and Luke Cage first started "Heroes for Hire", Bob went on a couple of missions for them. He also dated Colleen Wing off and on for a while.
Bob is now a Hollywood Oscar winning actor and stunt-man. He remains good friends with Luge Cage and Iron Fist.
He more recently encountered the X-Man Wolverine, while he was on a mission in the China Town section of San Fransisco.
