During his first stint with the promotion, Hankinson also appeared briefly as an imposter of the wrestler Kane during 2006 and then returned as Festus, a seemingly mentally handicapped character who teamed with Jesse (Ray Gordy), but the team achieved little success.  After disappearing from television, Hankinson later became the enforcer and "disciple" of CM Punk, sporting a cleaner, militant look, with the Festus character's "real identity" revealed as Luke Gallows.
