Before Hell in a Cell became another gimmick to strengthen one of WWE's second tier pay-per-views, the cell was the arena of choice to end the most intense feuds in WWE history.
Iconic moments, such as Mankind being thrown off the cell, Brock Lesnar leaving the Undertaker broken and bloodied, and Kane's inaugural appearance, have together crystallized the horror of the match. These memories helped create a special aura around Hell in a Cell matches, which further emphasized the importance of any match that was arranged for the structure.
Yet there are rivalries out there through WWE history that deserved a Hell in a Cell match—under its original menacing concept—but never happened. These five legendary feuds would not have been made better by the cell, as that is not the structure's purpose, but it would have created one last abiding memory.
