The short version: for whatever reason, someone in the WWF creative department thought that they could get a guy over by dressing him up as a giant bull. It didnt work. The (slightly) longer version? Their rationale must have gone something like this: Hm. Bulls are big, scary animals, so if we dress our guy up as one, hell look big and scary, too. Sadly, the end result looked more like a mentally challenged furry trying to make whoopee with a reject from a cowboy taxidermists workshop. Garishly clad in a costume that looked somewhere between Ross SPUDnik costume in that Friends Halloween episode and a bulls head stolen from a steakhouse wall, Mantaur stands head and shoulders over most other weird and/or stupid gimmicks in wrestling history. The real wonder here is not that the gimmick failed to work, rather that the worlds biggest wrestling company ploughed valuable time and money into developing it in the first place.
