Horace was abandoned by his mother at birth, and was raised by his father. As a child, Horace grew to such a grotesque height and appearance that he was constantly ostracized and spent his childhood as an outcast.
Mr. Mahoney put Horace to work at his junkyard, chopping and crushing up old cars. When Mr. Mahoney died, Horace was left alone and finally went insane. He became a serial killer, picking up hitchhikers and stranded motorists to take back to his junkyard; where he would rip them apart with his bare hands and feed their remains to his dogs. His preferred method of murder are what earned him the nickname, "Breaker".
Horace's seventh to-be victim turned out to be an undercover police officer, who had a SWAT team surround the junkyard, and arrest Horace. However, Horace was able to break free of his cuffs and killed three police officers before he was gunned down by five SWAT officers. They then added one final full volley of shots "just to be sure".
Following his death, Horace's spirit remained bound to earth and haunted the junkyard, brutally killing anyone who entered. This caused the junkyard's ghost population to rise to over forty by 2001.
Cyrus Kriticos and his team, including Dennis, arrive at the junkyard in approximately 2001 to capture Horace's ghost to become The Juggernaut. They use a tape-recorded Latin chant played across a megaphone to successfully draw The Juggernaut into a containment cube, but not before he savagely and brutally kills Cyrus's entire team, save Dennis.
The Juggernaut was then moved to the basement of Basileus's Machine with the other eleven ghosts. He is the twelfth and final ghost to be released, and once he is, he joins The Hammer in the attack on Dennis. Once the two overpower Dennis, The Juggernaut brutally finishes him off by breaking his back on a pole.
Shortly after, the Latin chant causes The Juggernaut, along with the other eleven ghosts, to go to the centre of the machine and power it up. When The Juggernaut and the other ghosts are freed from the trance, they throw Cyrus into a rotating crest of rings. The house then explodes, destroying its walls and freeing The Juggernaut and the other eleven ghosts.
- The whispers which signal The Juggernaut's approach appear to be roaring wind.
