#3 Isaac Yankem DDS
The Big Red Monster is one of the most legitimately intimidating gimmicks in WWE history.
Everything about him, from the pyrotechnics in his entrance, the tragic backstory between him and the Undertaker, the fact that he didn’t speak for the longest time and, ultimately, his dramatic unmasking, were all contributing factors towards that.

But before he painted the WWE red, Kane’s gimmick as a deranged dentist, Isaac Yankem DDS, armed with a dental drill and a ridiculously disarranged set of teeth, was how he made his WWE bow.
Yankem was initially booked to accompany Jerry Lawler and was supposed to scare the living daylights out of children (who, traditionally, detest trips to the dentist, right?). Only, it didn’t quite work out like that.
Poor booking led to his gimmick falling flat and Vince was forced to reckon with the fact that Isaac Yankem needed a massive character overhaul. And the rest, as they say, is history.
