3. The Great Khali
Good Lord where do I even begin with this? Despite being rubbish in the ring, there was a time before the whole "Punjabi Playboy" gimmick when the Great Khali was genuinely terrifying. In 2006 he made his debut by beating down the Undertaker. Yes, the Undertaker went out of his way to sell for the Great Khali! It was only when he actually wrestled (you know, that thing that wrestlers are sometimes required to do) that fans realized he was worthless. Yet that didn't stop WWE from booking him to win a battle royal to lift the vacant World Heavyweight Championship! Khali lost the title in his first defense to Batista. He has never held it since, though he has been booked in title matches, usually when star power is at an all time low. With his terrifying giant monster gimmick (really the only positive he had going for him) traded for the comedic dancing buffoonery, not to mention knees that can barely support his own weight, the WWE Universe can sleep soundly knowing that the Great Khali will never again hold any singles championship. Ever!
