Horace Mahoney is known as "The Juggernaut" in the film Thirteen Ghosts.
The Juggernaut is the ghost of a serial killer named Horace "Breaker" Mahoney. Standing 7 feet tall, he was of such grotesque height and appearance that everyone ostracized him as a child. His mother abandoned him at birth, so his father raised him, putting him to work in the junkyard crushing old cars.
After his father died, Horace was left on his own, and soon went mad. He would pick up female hitchhikers on the road and drive them back to his junkyard, then tear them apart with his bare hands and feed them to his dogs.
One day, he picked up an undercover female police officer, who called for backup, bringing a SWAT team to surround the junkyard. The police arrested the giant. However, Horace broke free and three officers lost their lives. Quickly, five SWAT officers took out their guns and brought Horace down in a hail of bullets. When he finally went down, they shot an extra round of ammunition into him "just to be safe." His ghost still shows bullet holes all over his clothing.
