#1 The Berserker

What is it with WWE and Vikings?
Back in the early 1990s, they planned to debut John Nord as "The Viking" which would have made sense as a moniker, however at the last minute they changed his name to the ludicrous, "Berserker" moniker.

In actuality, the name is historically accurate as an old Norse warrior, in the Viking age. But as most people know, it's most common association is with the word "berserk", meaning hysterical or insane. Hey, whoever came up with this moniker must have been berserk themselves.
To make matters worse, when The Berserker came to the ring he would repeatedly shout the word "Huss" over and over.
Unsurprisingly, Nord's Berserker character did not get over with the WWE audience, who admittedly were well used to gimmicks of this kind, demonstrating it's absurdity.
The Berserker was one step to far even for early 1990s WWE fans. The character barely lasted two years and was mercilessly scrapped in February of 1993.
The Berserker; the worst wrestling moniker of all time.
