The habitat of Parts Unknown has churned out many strange individuals, and The Moondogs were amongst the most bizarre groups to ever crawl out of the mysterious wasteland.
In the latter part of 1980, manager extraordinaire Captain Lou Albano introduced Moondog Rex and Moondog King to the WWE Universe. A pair of gruff, unkempt men that wore shredded jeans and carried chewed up bones to the ring, The Moondogs were unorthodox to say the least. Still, despite his team’s lack of polish, Albano guided them to victory after victory, which positioned Rex & King as the No. 1 contenders to the WWE Tag Team Championships, held at that time by Tony Garea & Rick Martel.
On March 17, 1981, Albano’s charges dethroned the champs to win the World Tag Team Titles. Shortly after their victory, however, King headed back to Parts Unknown. His disappearance signaled the entry of a third Moondog — Spot — who was every bit as vicious and maniacal (if not more) than King was.
