After Samu and Fatu joined the World Wrestling Federation, they were renamed The Headshrinkers, but their savage gimmick remained. Kokina Maximus also joined the WWF, but was repackaged as Japanese sumo wrestler Yokozuna, and his relation to The Headshrinkers was not acknowledged. The Headshrinker's first notable angle came when they interfered to help Money Inc. beat The Natural Disasters for the WWF World Tag Team Championship. Soon after, The Headshrinkers feuded with The Natural Disasters and the recently formed High Energy.
