There are plenty of characters that have come into the WWE over a number of years. They range from the comedic to the strange. They can even be terrible.
There is no way of knowing how a gimmick will be received so the only way to find the right formula is to keep trying.
One theme that has been used through the decades is the animal mascot. From trying to incorporate a feeling with a certain wrestler to making a nickname stand out, animals have been used by the WWE to get a certain gimmick over.
Most of the animals on this list are real, but all of them were entertaining.
