Recruited with friend Fred Dukes into Team X, John was one of the only people on the team who actually got along with the Wolverine. As such, when the Wolverine quit due to morals, so did John and Fred. Retiring to being a boxing manager, John tried to get Fred back in shape. When asked for help by the Wolverine to find Gambit, John accepted. However, not long after he was killed by Victor Creed.
Being a teleproter, John possessed the ability to move himself anywhere he wanted to go. However, he had never honed his abilities and thus never went too far off a certain radius.
